The system adopts centralized management, which can facilitate the use of each employee (which cabinet can be opened when and when) to each controller through the computer communication network.
third chapter.System functions and features
3.1 Design principles
RFID identification technology in the inventory management system must have cutting-edge technology, meet the needs of practical applications, and withstand the test of time. Therefore, the design of the inventory management system should comply with the following principles.
3.1.1 Practicability of the system
The content of the induction card management system of the employee goods cabinet should meet actual needs, and should not be flashy. If one-sided pursuit of the advancement of the system will inevitably result in excessive investment and deviate too far from actual needs. Therefore, the practicability of the system is the first principle that should be followed. The front-end products and system software of the system have good learnability and operability. Especially the operability, so that managers with basic computer operation level can master the operation essentials of the system through simple training, and achieve the ability to complete the duty The operational level of the task.
The induction card management system of the employee goods cabinet was designed with the current domestic practical application level in mind, and it can be fully utilized immediately after the system is completed. Use reasonable investment to get the best results. This is reflected in three aspects:
(1) On the premise of satisfying functionality and reliability, the initial total investment should be as small as possible.
(2) The management and maintenance cost after system operation is low.
(3) The system can be achieved with only a small amount of funds when changing or relocating and upgrading the system in the future.
3.1.2 The real-time nature of the system: if any of the key systems in the system has an error or shutdown, it will directly affect the operation of the entire system. Therefore, the various subsystems of the employee inventory management system should belong to the non-stop (not Shutdown) system to ensure normal operation
3.1.3 System integrity: complete functions, complete equipment, and convenient management are the factors that should be considered in the design of a complete employee inventory management system.
3.1.4 System security: All the equipment and accessories in the staff item cabinet induction card management system should be in safe and reliable operation, while also complying with relevant Chinese or international safety standards, and can work effectively in non-ideal environments. In addition, the security of the system should also be reflected in the aspects of information transmission and use, which are not easy to be robbed and stolen.
3.1.5 System scalability: The technology of the proximity card management system continues to advance, and user needs are also changing. Therefore, the design and implementation of the proximity card management system for the employee storage cabinet should take into account the actual needs of future scalability, namely : It can flexibly increase, decrease or update each subsystem to meet the needs of different periods, maintain a leading position for a long time, and become a model of intelligent management system. When the system is designed, a reasonable configuration is made for the functions that need to be realized, and this configuration can be changed. Even after the completion of the project, the configuration change is possible and convenient. The system software can be based on the developer, according to The needs of the market in different historical periods are upgraded and improved accordingly, and free software upgrades are provided for the corresponding application customers for free.
3.1.6 Easy maintenance of the system: The maintenance of the induction card management system of the staff item cabinet during operation should be as simple and easy as possible. The operation of the system is truly to the extent that it can work when the power is turned on, and it can be operated when it is plugged in. And there is no need to use too many dedicated maintenance tools during the maintenance process. From the configuration of the computer to the configuration of the system, the configuration of the front-end equipment fully considers the system reliability and implements the corresponding certification. While achieving the lowest system failure rate, we also consider that even because of unexpected reasons When a problem occurs, ensure the convenient storage and rapid recovery of data, and ensure that the channel can be opened quickly in an emergency. The maintenance of the entire system is online, and the normal operation of all equipment will not be stopped due to the maintenance of some equipment.
3.1.7 System stability: The products used in this system have experienced market applications for more than 3 years and gradually upgraded to mature products, especially there are many successful cases in China.
All in all, as an enterprise facing the 21st century, the intelligent system must first be advanced to meet the needs of future development. Therefore, the design ideas must be advanced, and the selected system equipment and software must be relatively advanced in the world.
3.1.8 Design basis
The main design basis includes:
1. International integrated wiring standard ISO/IEC11801
2. “Code for Electrical Design of Civil Buildings” JGJ/T 16-92
3. “The People’s Republic of China Security Industry Standard” GA/T74-94
4. “People’s Republic of China Public Safety Industry Standard” GA/T70-94
5. “Engineering Technical Code for Monitoring System” GB/50198-94
3.2 Main functions
Taking a container area as an example, this system has the following functions:
A. The card is sensed on the card reader, and the corresponding item cabinet opens.
B.Real-time display on the computer which container number is opened, as well as time and personnel information
C. It can be achieved that one card corresponds to one item cabinet, one card corresponds to multiple item cabinets, and multiple cards correspond to one item cabinet, etc., multiple ways of operating the item cabinet.
D. The fixed card and the temporary card can be used at the same time, the fixed card can be specifically assigned to someone, and the temporary card can also be used as a special situation.
E. Use centralized management. Through the communication network, the computer can easily download the use authority of each employee to each controller. There is no need to register in the controller one by one.
F. Run offline. When the communication network is interrupted, the administrator can directly register each card on the controller through the menu operation on the controller.

instruction:
(1) Each SK400C network controller can be connected to up to 32 SK400L controllers. Taking into account the safety and cost factors of the system, the system requires a total of 4 network controllers.
(2) Each SK400L controller can control 68 staff cabinets, called a zone. Therefore, 6,000 staff cabinets require 98 controllers.
(3) In addition to a controller, each zone also needs a card reader, 4 SK-16DO modules, and a regulated power supply.
Chapter 5 System Composition
The system is composed of two parts: software and hardware. The software part is mainly responsible for analyzing, storing and processing data, and finally sorting out the records of opening and closing doors of all cabinets. The hardware part is mainly composed of network controller, controller, converter, 16DO module, card reader, etc.
The functions are as follows:
1) Controller: It is the core of the automated management of the entire goods cabinet. It is responsible for receiving the card number from the card reader, and after the controller’s judgment, it determines which item cabinet’s relay action on the DO module corresponds to. Each controller can control 68 staff cabinets.
2) 485 converter: It is responsible for converting the 485 signal from the controller into 232 signal and then enter the computer serial port.
3) DO module: it is the expansion module of the item cabinet control, which is connected with the intelligent control part of the item cabinet. A DO module has 16 relays, and each relay can correspond to the control of an item cabinet. Up to 4 16DO modules can be connected to one controller.
4) Card reader: used to read the card information carried by the cardholder. The sensing distance is 4-12CM. Install one outside the door of the goods cabinet, which is used to open the goods cabinet and swipe the card to confirm the identity.
5) Proximity card: The number depends on the number of cardholders of the user. Employees and managers have one card, and open the goods cabinet according to the authorization set by the system. The future expansion can realize the stored value consumption function of the electronic wallet.
6) Power supply: provide power to the controller, card reader, etc. The input power is taken from a local power supply socket or a centralized power supply central control room UPS.
7) Back-up battery: used to provide power for all parts of the system in the event of a sudden power failure.
