[0022] With reference to the accompanying drawings, the specific implementation of the present invention will be further described in detail through the description of the best embodiment.
[0023] Material backups of production enterprises often set up transit warehouses and same-day warehouses. The same-day warehouses are used to realize materials that meet the production requirements of the day, and the transit warehouses are warehouses for storage and transfer. In order to achieve rapid and reliable material distribution request deployment , Realize the data allocation request and related request records of the two warehouses based on the Industrial Internet of Things to improve the efficiency of distribution. The specific principle is as follows:
[0024] Such as figure 1 As shown, a production management and control system based on the Industrial Internet of Things includes a material demand system set in a warehouse of the day and a material distribution system set in a transfer warehouse. The transfer warehouse is a large warehouse and stores more materials, while the same-day warehouse In order to meet at least the internal library of the production plant area produced on the day, it is necessary to call the materials in the transfer library from the transfer library on demand. The material requirement system is used to input material requirement information and the identity information of the requester. It connects to the verification server through the industrial Internet; the verification server verifies the received identity information of the requester and sends the material requirement information and the identity of the requester after the verification is passed. It is sent to the material distribution system, and the relevant request information is stored in the verification server. The material distribution system generates a distribution request from the received material demand information and requester information.
[0025] Such as figure 2 , The material demand system includes a controller for data processing, a demand information entry module, an identity information acquisition module, and a communication module. The input of the controller is connected to the demand information entry module and the identity information acquisition module, and the output of the controller passes through The communication module is connected to the authentication server. The identity information collection module includes one or more of a fingerprint collection module, a voiceprint collection module, an iris information collection module, and a face recognition module. Correspondingly, the fingerprint of the requester who can make material requests is preset in the verification server, Voiceprint, iris, face and other information.
[0026] In the database of the day, the requester with the function of dispatching materials enters the required information such as the quantity, size, type, transportation location, etc. of the required materials through the demand information entry module, and at the same time collects his own identity information through the identity collection module, and then controls The device is uploaded to the verification server through the communication unit. The demand information input module is realized by a touch screen with human-computer interaction. The controller adopts an industrial-grade PLC controller. After obtaining the demand information entered on the touch screen, the PLC controller sends the data to the verification server through the communication chip.
[0027] The verification server has functions such as data forwarding, processing, and storage. After receiving the incoming material requirement information and the identity of the requester, the identity of the requester is first verified. When the identity information of the requester is preset in the verification server, that is, the identity information of the requester and the pre-defined identity information. When the stored identity information matches, the server material requirement information and the identity of the requester are verified for storage, and the data is transferred to the material distribution system through the network, so as to deliver according to the required information through the transit warehouse.
[0028] One or more preset requester identity information is pre-set in the authentication server, and the identity information of the personnel who can allocate materials is set according to actual needs, which is confirmed by the actual management personnel of the production line, and all personnel who can perform material deployment are pre-set The identity information is preset in the verification server (identity information corresponds to the information collected by the identity collection module, including fingerprints, faces, voiceprints, iris, etc.), and the verification server combines the requester information sent by the material requirements system with the preset The identity information of the requester is compared and verified, and the verification is judged to pass when the identity information of the requester sent by the material demand system is consistent with the preset requester information. For example, the uploaded fingerprint information. At this time, the verification server compares the uploaded fingerprint data with the preset fingerprint information of the management personnel who can make material requests to check whether it is one of the management personnel. If the fingerprint comparison finds The fingerprint information of one of the pre-requesters will be verified, and the material requirement information and the relevant information of the corresponding requester will be saved and sent to the material distribution system at the same time.
[0029] Such as image 3 As shown, the material distribution system includes a main control unit, a communication unit, and a display unit. The main control unit receives the identity information of the requestor and the corresponding material demand information after the verification server has passed the verification through the communication unit. The output terminal of the main control unit and the display unit Connection, used to control the display unit to display material requirement information and requester information. The main control unit adopts industrial grade PLC controller or directly adopts industrial grade computer. After acquiring and receiving the data control from the verification server through the communication unit (the established industrial network), the main control unit drives the display to display, display material demand information to facilitate understanding of material distribution requirements, and display requester information to facilitate confirmation of the final Which manager is the requester?
[0030] Further, in order to achieve the function of the bill of lading, not only the display of material requirements is displayed, but also the paper request receipt is automatically printed out, so as to facilitate the transportation part of the transit warehouse to carry out material distribution according to the paper transportation receipt. To this end, the main control unit is connected to the printer, and the main control unit generates a material transportation bill according to the received material demand information and the identity information of the requester, and generates a paper transportation bill by controlling the printer. Paper transportation documents can be held by the transportation personnel in the transit warehouse and material distribution can be carried out based on relevant information.
[0031] Preferably, the main control unit is connected with the voice module, and is used to give a voice reminder after receiving the material demand information and the requester's identity information. In order to promptly and effectively remind the transportation management and other personnel in the transit warehouse to transport in time, when the demand information is received, the main control unit drives the voice module to give a reminder signal to remind them to check in time. The voice module may include a voice chip and a speaker, and the voice chip controls the speaker to emit a preset reminder voice to give a reminder.
[0032] Preferably, in order to enable the material demand system to know the confirmation information of the material distribution system in time, the material distribution system also includes a transportation confirmation module for giving confirmation information; the transportation confirmation module is connected to the main control unit to collect information from the material distribution personnel Confirm the information, and feedback the confirmation signal of the material distribution requirement to the material requirement system through the verification server, and then the touch screen in the material requirement system displays the confirmation information. The transportation confirmation module includes a confirmation button, which is connected to the main control unit, and is used to send a confirmation message to the main control unit through the confirmation button after receiving relevant demand information, and then the main control unit feeds back the confirmation signal through the communication unit and the verification server To the material requirement system. The main purpose of this is to let the demand side know that the transit warehouse has obtained relevant demand information and gave feedback.
[0033] A management and control method for a material management and control system based on the Industrial Internet of Things, including the following steps: Step 1, input material requirement information and corresponding requester identity information through the material requirement system, and upload it to a verification server;
[0034] Step 2: The verification server verifies the identity information of the requester corresponding to the material requirement information, and sends the material requirement information and the corresponding identity information of the requestor to the material distribution system after the verification is passed;
[0035] Step 3: The material distribution system generates a transportation bill from the material demand information and the requester's identity information, and displays or prints it into a paper transportation bill to notify the transportation personnel.
[0036] Step 4. The material requirement system obtains the confirmation information of the material transportation personnel through the transportation determination module and feeds the material transportation information back to the material requirement system for feedback.
[0037] Obviously, the specific implementation of the present invention is not limited by the foregoing manners, as long as various insubstantial improvements made by adopting the method concept and technical solution of the present invention are within the protection scope of the present invention.
