Description:
TECHNICAL FIELD OF THE INVENTION 
       [0001]    The invention relates to the field of automated logistics and automated production, in particular to an automated logistics system using a triggering-forwarding device. 
       TECHNICAL BACKGROUND OF THE INVENTION 
       [0002]    In the production and logistics field, the automated management information technology is relatively lagging behind, part of enterprises do not have a information system for production and logistics and even though some enterprises have the logistics information system, service functions and hardware equipment of the information system of the enterprises are all imperfect, the logistics information system is short of necessary system modules on the aspects of production management module, warehouse management, cargo tracking, transportation management and the like and capability of integrating logistics information resources is still not formed, much less automation of production and logistics management. 
         [0003]    Management of the logistics industry has roughly gone through the following four stages: 
         [0004]    the first stage of management of the logistics industry, wherein 
         [0005]    management of the logistics industry is mainly completed by manually identifying information and manually inputting the information into a computer, so that not only is labor wasted, but also accuracy of the information cannot be ensured and more crucially, a great number of paper documents are difficult to perfectly store and difficulty in information search is high; 
         [0006]    the second stage of bar code input automation of the logistics industry, wherein 
         [0007]    related information of products is identified by bar codes; the bar codes are manually scanned into a computer one by one; and the second stage is improved relative to the first stage of inputting the information totally by a keyboard, however, the bar codes still need to be singly input one by one and the second stage is very wasteful for human resources; 
         [0008]    the third stage of radio frequency identification device (RFID) automated logistics of the logistics industry, wherein 
         [0009]    related information of products is automatically identified by RFIDs; an identification result is automatically input into a computer; the computer judges accuracy of input product information and carries out voice prompt; the information is manually stored into software of a logistics system according to a prompt result or storage is canceled; manual operation and manual judgment are still required; and human resources are greatly wasted; 
         [0010]    the fourth stage of RFID full-automated logistics of the logistics industry, wherein 
         [0011]    on the basis of the third stage, infrared sensors, pressure-sensitive sensors, temperature sensors and the like are added, however, the sensors have a certain defects in a certain special application environments; for example, the infrared sensors and the pressure-sensitive sensors cannot be started and stopped according to subjective thinking of people, triggering of information also does not have accurate target, and as long as objects pass through the infrared sensors and the pressure-sensitive sensors, the infrared sensors and the pressure-sensitive sensors can be triggered and can send out uncertain information, so that other automatic equipment in each scene abnormally works; and in addition, all the sensors currently provided in the market do not have an information feedback function. 
         [0012]    Logistics automation in the fourth stage still remains at the level of operating the automatic equipment by specially-assigned people or is complete intelligent automation. Complete intelligent automation brings great difficulty to logical analysis and judgment of the computer and once the information is inaccurate, more errors and manual check work are possibly caused. According to the prior art, to achieve complete intelligent production and logistics automation, corresponding hardware and software equipment is still immature and still needs to be further researched and developed.

         [0036]    (5) after the triggering-forwarding device is used in each scene, feedback information can be timely obtained, which is convenient to timely solve the error problem; other hardware and software are started to work by the device, RFIDs automatically carry out identification, the software system analyzes and judges accuracy that the RFID reader-writer reads the data and a result is directly fed back on a liquid crystal display (LCD) screen (or an LED display screen) of the device, so that users can directly and visually observe the result, find errors at first time and correct the errors, and thus, error probability in the enterprise production and logistics process is reduced and the management level of the enterprise is improved; 
         [0037]    (6) the employment threshold of related operation personnel is reduced and training cost of the enterprise is reduced; and operation is simplified, only simple manual operation needs to be carried out and other automatic equipment in each scene can correspondingly work according to intentions of people by pressing down a certain button on the triggering-forwarding device (people determine to press the buttons according to the requirements of actual businesses in each scene); 
         [0038]    2, benefits brought when the enterprise uses the scenes, wherein 
         [0039]    (1) the enterprise integrates information of various scenes in the production and logistics by the software system, enriches all information in the production process of products, provides effectively and complete data support and can better control product quality; 
         [0040]    (2) when using an automated ex-warehousing scene of empty container and combining material requirement planning (MRP) software, the enterprise can accurately know a current container condition and demand of empty containers (boxes) in the workshop field and can timely carry out distribution and delivery as required; 
         [0041]    (3) when the enterprise uses a finished product warehousing scene and combines MRP stock-sell-storage software, firstly, a current inventory status of a warehouse can be clearly, accurately and rapidly searched and even information, such as current materials in the warehouse, placement positions of the materials, the number of the materials and the like, can be known; secondly, the positions of cargoes in the warehouse can be accurately positioned, labor cost is reduced and production efficiency is improved; and thirdly, a first-in first-out system can be better executed and backlogging of warehouse cargoes is reduced; 
         [0042]    (4) when using an automated recovery scene of empty container and combining empty container recovery software, the enterprise can look up the number of empty containers retained at a client at any time.

The triggering-forwarding device  5  also can receive feedback information of the computer  3  and display the feedback information by the built-in display module  54  of the triggering-forwarding device  5 . 
         [0057]    By matching with corresponding RFID logistics management system software, the system flexibly applies various external automated identification equipment and relay control devices (the RFID reader-writer  2 , the RFID chips  1 , the scanning gun  7 , the labels  6  and the triggering-forwarding device  5 ) and timely inputs information of production, warehousing, ex-warehousing and the like of an enterprise into a database. According to records of the information in the database, powerful data support is provided for cargo handling, ex-warehousing cargo preparation, counting, recovery of empty containers returned by clients, product responsibility tracking and the like of a warehouse, and production and logistics operation is guaranteed to be carried out in order by the rules. 
         [0058]    At the present stage, the system disclosed by the invention is mainly applied to an automated warehousing scene, an automated ex-warehousing scene of empty container and an automated recovery scene of empty container. 
         [0059]    The embodiment 1 shows application of the triggering-forwarding device in the automated warehousing scene: 
         [0060]    the triggering-forwarding device  5  is applied to the automated warehousing scene, and character information of clusters is manually given to the buttons of the triggering-forwarding device according to the actual requirements of businesses; each button  521  respectively represents the number of clusters which need to be warehoused (one cluster means one set, i.e. the same cluster number is given to a plurality of containers which need to be warehoused according to a certain number, namely, the containers with the same cluster number belong to the same cluster); the human brain judges which button on the triggering-forwarding device  5  should be pressed according to the actual condition of warehousing, a judgment result of the human brain is forwarded to the software system, and simultaneously, other automatic equipment is enabled to enter the operating state; and the software system can accurately know which labels shall be read in the current scene according to command information sent out by the triggering-forwarding device  5  without complex logical judgment and feed back a result to the triggering-forwarding device  5  (or display the result on the LED display screen  4 ) after execution is completed. 
         [0061]    Specific operation is as follows: 
         [0062]    warehousing work does not require special personnel to operate the software system and as long as handling personnel completes one simple button pressing action, the triggering-forwarding device  5  can automatically complete work of starting the RFID reader-writer  2 , the LED display screen  4  and the logistics software system and the system can automatically complete warehousing actions of products, such as warehousing billing, display and printing actions. 
         [0063]    In the embodiment, one button  521  on the triggering-forwarding device  5  is pressed down mutually to forward the judgment result of personnel, such as the judgment result of one cluster, to the software system arranged on the computer  3  and the software system receives information, i.e. one cluster needs to be warehoused, which is sent out by the device; the RFID reader-writer  2  only reads data that one cluster is warehoused according to the information sent out by the triggering-forwarding device  5  and transmits corresponding data to the software system, the software system carries out analysis and judgment, a result is directly displayed on the LCD screen of the display module  54  of the triggering-forwarding device  5  (i.e. the triggering-forwarding device  5  receives information fed back by the software system), and certainly, voice prompt can be carried out in the feedback process in certain embodiments; and certainly, the information fed back by the software also can be directly displayed on the LED display screen  4  and suitable arrangement is carried out according to the requirements of each scene. Again for example, when a worker presses down the button  521  which represents the number of 2, the judgment result of two clusters of the worker is forwarded to the software system by the device and the software system receives information, i.e. two clusters need to be warehoused, which is sent out by the device; and the RFID reader-writer  2  only reads data that two clusters are warehoused according to the information sent out by the triggering-forwarding device  5  and transmits corresponding data to the software system, the software system carries out analysis and judgment, a result is directly displayed on the triggering-forwarding device  5  and voice prompt (OK) is carried out. By the analogy, if the RFID reader-writer  2  reads the cluster number of three or one when warehousing personnel presses down the button  521  which represents the number of 2, the triggering-forwarding device  5  can prompt an error of warehousing information (or the error is prompted by the LED display screen  4 ), the RFID reader-writer  2  stops reading, the warehousing personnel views the error information from an automated warehousing error list and corrects the error, and the clusters can be warehoused after the information is accurate. 
         [0064]    The flow of the embodiment 1 is as shown in  FIG. 2 . 
         [0065]    The embodiment 2 shows application of the triggering-forwarding device in the automated ex-warehousing scene of empty container: 
         [0066]    the triggering-forwarding device  5  is applied to the automated ex-warehousing scene of empty container and, character information of reread, cancel, confirmation and the like is manually given to the buttons  521  of the triggering-forwarding device  5  according to the actual requirements of businesses; and the scanning gun  7  is connected by utilizing one USB interface of the triggering-forwarding device  5  to upload the scanned information of one bar code  6  to the software system, the information possibly is certain parameters and a document number which are required by the software system, or logical judgment basis, and the logical judgment basis is compared with actual data read by the RFID reader-writer  2  to obtain accurate logical judgment. 
         [0067]    Specific operation is as follows: 
         [0068]    warehousing personnel utilizes the scanning gun  7  externally connected to the triggering-forwarding device  5  to scan one bar codes  6  on an empty container application document, scanned related information of the application document is uploaded to the software system by the triggering-forwarding device  5 , simultaneously, peripheral equipment is started to work and as long as the warehousing personnel pulls empty containers to pass through an RFID automated identification region, the system can automatically complete checking the type of the containers; and personnel takes the following actions according to check results: (1) when the type is checked as correct and is consistent with a number visually inspected by the personnel, the button  521  which represents confirmation is pressed down to carry out storage; (2) when the type is checked as wrong, the system can send error prompt to the triggering-forwarding device  5  and displays error information on the LED display screen  4 , at the moment, manual judgment needs to be carried out to determine a document error, or label damage and the like, and after error processing is finished, a user can press down the button  521  which represents reread to obtain correct data; and (3) when the type is checked as correct, but the number read by the RFID reader-writer  2  is inconsistent with an actual required number, the user presses down the button  521  which represents cancel to cancel all data which is not filed. All the operation above is the process that the triggering-forwarding device  5  forwards the judgment results of personnel to the software system. 
         [0069]    The flow of the embodiment 2 is as shown in  FIG. 3 . 
         [0070]    The embodiment 3 shows application in the automated recovery scene of empty container in the field of logistics: 
         [0071]    the triggering-forwarding device  5  is applied in the automated recovery scene of empty container and, character information of start, pause, completion and the like is manually given to the buttons  521  of the triggering-forwarding device  5  according to actual requirements of businesses; personnel judges whether to trigger the buttons on the device according to the actual condition of empty container recovery, a command of the personnel is forwarded to the software system, the software system directly starts or stops work of other automatic equipment (card reading of the RFID reader-writer  2  and display of the LED display screen on the related process) without complex logical judgment after receiving the command; and in the scene, the triggering-forwarding device  5  just simply forwards the command of the personnel to the related software system. 
         [0072]    Specification operation is as follows: 
         [0073]    recovery personnel presses down the button  521  which represents start on the triggering-forwarding device  5  to enable empty containers which are returned from clients and need to be recovered to pass through the RFID automated identification region and the system can automatically clear up original information of the containers to enable the containers to be returned to an initial available state; personnel gives a command to the device according to the actual condition of container recovery and presses down the button  521  which represents start, the triggering-forwarding device  5  receives the command sent out by the personnel and starts the RFID reader-writer  2  to carry out card reading, and the LED display screen  4  displays a current reading condition convenient for the software system to judge and store related information; the button  521  which represents pause is pressed down, the device temporarily stops the RFID reader-writer  2  from reading the labels according to the command sent out by the personnel and read label information is added into the system; and the button  521  which represents completion is pressed down and the triggering-forwarding device  5  finishes the empty container recovery work according to the command sent out by the personnel. 
         [0074]    The flow of the embodiment 3 is as shown in  FIG. 4 . 
         [0075]    In the logistics automation process, the invention carries out analysis and comparison on special operation automation and intelligent automation in details, refines each business stage and determines which judgment needs to be completed by human brains and which judgment needs to be automatically completed by the computer to avoid sending out wrong commands to the automatic equipment so as to ensure that the automatic equipment correctly completes related work. 
         [0076]    To integrate logical judgment of personnel into the process of integral logistics automation, the invention adds the triggering-forwarding device in the automated logistics scenes. The triggering-forwarding device generally plays the following functions in each scene of production and logistics: triggering, forwarding and receiving/feedback, wherein triggering aims to enable other equipment in the integral scenes to enter the operating state at proper moment; forwarding means that part of judgment results of personnel or judgment of other equipment is forwarded to the software system by the equipment, so that the software system can easily send out the correct commands to other automatic equipment in the scenes; and receiving/feedback means that a result of data execution in the automation process is directly received and is shown in character and voice prompt forms without additionally adding other equipment to complete the work. Addition of the device brings great convenience to programming of automated logistics software and simplifies complex logical judgment. 
         [0077]    The above is only the preferred embodiments of the invention and not intended to limit the scope of protection of the invention, and any solution for implementing the aim of the invention by basically same means shall belong to the scope of protection of the invention.
