The worker terminal may generate answer information on queries related to forklift inspection based on the received query information. According to an example embodiment, the query information may include safety matters to be confirmed by a driver before the operation of the forklift is started. 
     According to an example embodiment, the answer information generated through the worker terminal may be transmitted to the apparatus  100  when any object (for example, a completion button) is selected. 
     According to an example embodiment, the apparatus  100  may transmit approval information indicating whether a worker may start a job based on the received answer information to the worker terminal. 
     According to an example embodiment, when it is determined that a worker may start a job according to the answer information, the approval information indicating that the start of the job to be performed by the worker is approved may be transmitted to the worker terminal. 
     According to an example embodiment, the apparatus  100  may determine that the job is performed by the worker and store the job while transmitting the approval information to approve the start of the job to the worker terminal. According to an example embodiment, when it is determined that a worker may not start a job according to the answer information, the approval information indicating that the start of the job to be performed by the worker is not approved may be transmitted to the worker terminal. The fact that the start of the job is not approved and, if not approved, an instruction (for example, hang a red tag on a lever, park in a designated location, and return a key) for a preset job process may be displayed on the worker terminal that has received the approval information indicating that the start of the job is not approved. According to an example embodiment, additional information to guide starting a job through another asset may be displayed on the worker terminal that has received the approval information indicating that the start of the job is not approved. According to an example embodiment, when the reason why the start of the job is not approved is that there is a problem with the asset, a worker may transmit only job starting information that changes only the asset to another asset to the apparatus  100 , and therefore, when any object (for example, a button to use another forklift) provided on a screen indicating that the start of the job is not approved is selected, the generated job starting information (for example, using another forklift) may be transmitted to the apparatus  100  by performing the process of modifying only the information on the relevant asset through the worker terminal again. 
       FIGS. 6, 7A, and 7B  are diagrams for describing a process of modifying and/or storing query information displayed on a worker terminal according to an example embodiment. 
     According to an example embodiment, the apparatus  100  may determine and store query information corresponding to job starting information received by a worker terminal in advance. According to an example embodiment, the apparatus  100  may set, modify, and/or store at least one step to be performed in performing a job identified according to job starting information received by a worker terminal. According to an example embodiment, the pre-stored query information may be modified and/or stored as query information for each step for each job. According to an example embodiment, when the worker terminal displays query information for each step, the apparatus  100  may additionally display guide information on the corresponding step (for example, a step guide (description)). According to an example embodiment, as one of the steps of starting a forklift driving job, query information on the driving start step may be stored, and a description (for example, safety equipment inspection) related to the driving start step may be additionally displayed. 
     According to an example embodiment, the apparatus  100  may modify and/or store information to be displayed as the query information for each step. According to an example embodiment, there may be at least one of query information related to the step, and at least one of question content, question guide information, or related images for each piece of query information may be modified and/or stored as query information to be displayed on the worker terminal. 
     According to an example embodiment, the query information modified and/or stored by the apparatus  100  may be transmitted to the worker terminal as query information for each step for a job that a worker intends to perform. According to an example embodiment, the apparatus  100  may determine and store a format of the answer information for the query information in advance. According to an example embodiment, the query information may include a format for selecting one of a plurality of pre-selected options, a format including text information created by a worker, and a format for selecting an image as the format of the answer information to be created by the worker terminal and may be a combination of these various formats. 
     Referring to  FIG. 6 , according to an example embodiment, the query information may be query information provided in a safety inspection step that may need to be performed prior to starting to drive a vehicle. According to an example embodiment, the query information may include a question about whether a black box of a vehicle to be driven is normal and may include a question guide for the question. According to an example embodiment, a related image to help a worker understand a question may be stored in advance in relation to the query information. According to an example embodiment, the apparatus  100  may modify and/or store an answer type to query information as having a format such as multiple choice (choose one), multiple choice (choose one or more), and short answer. According to an example embodiment, the apparatus  100  may store information related to an answer in advance. For example, the apparatus  100  may modify and/or store text information (for example, normal/bad), an answer guide (for example, when a power light for a black box is not turned on, it is answered as bad), and an answer guide image (for example, photographing a normal black box or photographing a defective part of the black box), and information on whether to ask an additional question that are related to each of the multiple-choice type answers set to select at least one answer. 
     Referring to  FIG. 7A , according to an example embodiment, the apparatus  100  may display the pre-stored image information as the query information related to each step on a query information display window. For example, when at least one of equipment whose query information is damaged is selected, image information representing each piece of equipment may be displayed along with a question. 
     Referring to  FIG. 7A , according to an example embodiment, an answer guide for an answer that may be selected for query information may include additional information to be provided to a worker in relation to the corresponding answer. For example, what is a normal answer (for example, the correct answer is “no damage”), an instruction to inform a manager when a bumper car is damaged, and information on a request for attachment of an image, video, audio, and the like for the damaged equipment may be provided to a worker who selects an answer that an equipment bumper is damaged through a worker terminal. 
     According to an example embodiment, when the answer information corresponding to the query information is received, the apparatus  100  may determine not to allow the corresponding job to start according to what the corresponding answer is. According to an example embodiment, the apparatus  100  may be set and stored not to allow the start of the corresponding job for each selected answer. Referring to  FIG. 7A , according to an example embodiment, at least one of the answers (for example, damage to a battery connector, damage to a head guard, breakage of an equipment bumper, damage to operating parts such as a handle, a lever, and a button, and the like) that may be selected in response to query information on whether there is damage, such as breakage or a dent, in the equipment may be set in advance to determine that a worker is not allowed to start a job. Therefore, when an answer preset not to allow a job to start is determined as being selected in the answer information from the worker terminal, the apparatus  100  may generate approval information indicating that the start of the job is not allowed and transmit the approval information to the worker terminal. 
     According to an example embodiment, the apparatus  100  may store a preset answer not to allow a job to start according to an answer for each job, for each step for performing a job, or for each piece of query information on a job. That is, the process that does not allow a job to start may be set not to be performed or conversely may be set to be performed, regardless of the job, the step necessary to perform the job, or what the answer for each piece of query information on the job is. 
     Referring to  FIG. 7B , according to an example embodiment, the apparatus  100  may modify and/or store the query information so that the image related to the answer is displayed as an answer guide image for an answer that may be selected for query information. According to an example embodiment, a worker may determine whether the corresponding answer is a correct answer by referring to the displayed answer guide image and select an answer. 
     Referring to  FIG. 7B , according to an example embodiment, the apparatus  100  may set whether to allow a worker to attach an image when the worker makes an answer in relation to an answer that may be selected for query information. According to an example embodiment, when an answer corresponds to damage to any equipment, a request to add the image information or the like as the answer information for the query information may be provided to the worker through the worker terminal. 
       FIG. 8  is a diagram for describing additional query information that may be additionally provided according to answer information of a worker according to an example embodiment. 
     According to an example embodiment, when the answer information for the query information corresponds to the preset answer information to provide the additional query information to the worker, the apparatus  100  may modify and/or store the additional query information to additionally transmit the additional query information corresponding to the answer to the worker terminal. For example, the apparatus  100  may determine to transmit the additional query information for at least one of the answers that may be selected for the query information to the worker terminal and store the determined additional query information, and the additional query information related to each answer may be different for each answer. For example, referring to  FIG. 8 , the worker terminal may generate answer information as “yes” or “no” to a query about whether an instrument panel is operating normally, a remaining charge in a battery is 60% or more, and a pallet latch footrest is operating normally and may transmit the generated answer information to the apparatus  100 . In this case, the apparatus  100  may not transmit additional query information for the answer information of “yes” to the worker terminal or may transmit additional query information different from the addition query information for the answer information of “no” to the worker terminal while transmitting the additional query information for the answer information of “no” to the worker terminal. 
     According to an example embodiment, the worker terminal receiving the additional query information may transmit additional answer information generated through answers in various formats, such as text information, image information, video information, and audio information, to the apparatus  100 . 
     According to an example embodiment, the process of modifying and/or storing additional query information by the apparatus  100  may be the same as or similar to the process of modifying and/or storing the above-described query information, and therefore a detailed description thereof will be omitted. 
     According to an example embodiment, the processor  120  may be further configured to modify at least one of the query information or the predetermined answer information. According to an example embodiment, the query information and/or the predetermined answer information transmitted and received from the transceiver  110  may be modified by the processor  120 , and the modified information may be stored in the memory and thus used as the query information to be transmitted later to the worker terminal and the predetermined answer information for comparison with the received answer information to determine whether a worker performs a job in a predetermined manner.
