## Background
BACKGROUND OF INVENTION
1. Field of Invention
The present invention relates to a computer-aided warehouse that enables operators to instantly monitor its operation and immediately and correctly take actions to correct errors whenever they occur, thus reducing errors and saving labor.
2. Related Prior Art
Warehouses are used to store various types of stuff. As the stuff becomes more and more in quantity or more and more dangerous, the need for a reliable warehouse gets stronger and stronger. For example, radioactive waste generates free radiation that is hazardous to humans and the natural environment. Therefore, the management of the radioactive waste is extremely important. As different kinds of the radioactive waste are handled in different manners, the intensity of the radiation generated thereby varies, and the locations and periods of time for the storage thereof differ from one another. The task of a warehouse for the radioactive waste is complicated and important. To this end, there have been developed various processes, devices and systems such as disclosed in Taiwanese Patent Publication Nos. 80683, 154931 and 281996.
However, to the best knowledge of the present applicant, there has not been any automatic access control system for the radioactive waste. Therefore, in access control over the radioactive waste ranging from application, examination, processing, conveying and storage, much labor is wasted and many errors are made in the processing of the related information. What is worse, operators might contact radioactive waste for too long. It is hence very likely that the operators could be exposed to radiation that is too much for them to take. The safety of the operators is jeopardized.
In co-pending Taiwanese Patent Application No. 094110294 filed by the present applicant, there is disclosed an automatic access control system that automates a warehousing process ranging from application, conveying and storage, and increases the efficiency, accuracy and security in the warehousing process.
The automatic access control system is focused on a person-less operation. Conventional single-functional monitor systems are however inadequate for monitoring the operation of the automatic access control system. Therefore, there is a need for a monitor system that enables operators to instantly monitor the operation of the automatic access control system and immediately and accurately take actions to correct errors whenever they occur, thus ensuring the security of stuff and the safety of operators.
The present invention is therefore intended to obviate or at least alleviate the problems encountered in prior art.
SUMMARY OF INVENTION
It is the primary objective of the present invention to provide a computer-aided warehouse with an access control system and a monitor system that enables operators to instantly monitor the access control system and immediately and accurately take actions to correct errors whenever they occur, thus ensuring the security of stuff and the safety of operators.
According to the present invention, a monitor system includes a server, a database stage, an operation stage, a monitor stage and a display stage. The database stage is connected to the server for storing various types of data related to access control over stuff. The operation stage includes a plurality of operation units connected to the server for taking actions related to the access control over the stuff. The monitor stage includes a plurality of monitor platforms connected to the server for monitoring scenes of the operation units of the operation stage. The display stage is connected to the server for showing various combinations of the scenes of the operation units.
Other objectives, advantages and features of the present invention will become apparent from the following description referring to the attached drawings.

The monitor system includes a server 10, a monitor stage 20, a display stage 30, a database stage 40 and an operation stage 50. All of the monitor stage 20, the display stage 30, the database stage 40 and the operation stage 50 are connected to the server 10.
The monitor stage 20 includes hosts 21 through 26 connected to the server 10. The host 21 is a monitor platform 21 used to control the operation of environmental radiation monitor devices. The host 22 is a monitor platform used to control the operation of laser-guided vehicles (øLGVø). The host 23 is a monitor platform used to control the routes of the LGV. The host 24 is a monitor platform used to integrate the operation of the monitor platforms 21 through 23. The host 25 is a monitor platform used to process scenes of the operation stage and pictures displayed on the hosts 21 through 26. The host 26 is a monitor platform used to store data.
The display stage 30 is connected to the server 10. The display stage 30 may be a single display with a screen that can be divided into many segments or a combination of displays that are made separately and joined together so that pictures displayed on them can be viewed as parts of a larger picture. For example, the screen of such a display can be divided into 4 or 16 segments. Alternatively, 4 or 16 displays can be connected to one another. The display stage 30 is arranged along an arc so that it can clearly be viewed by operators from different angles. All of the pictures of the monitor platforms 21 through 26 can be transmitted to and shown on the display stage 30.
The database stage 40 includes memories 41, 43, 45 and 47 connected to the server 10. The memory 41 is used to store data related to applications for access to stuff such as radioactive waste.
