1. Current situation analysis
In recent years, as a new type of retail industry, large supermarket chains have brought about a second revolution in commerce, and they are developing rapidly and vigorously. The distribution center is the distribution center of logistics and distribution. The experience of many large and medium chain supermarkets in the process of operation is that there will be no stable and healthy development of chain supermarkets without distribution centers. Therefore, chain supermarkets must pay attention to the construction of distribution centers. Give extremely high attention. The distribution and transportation from the distribution center to the branch is also one of the most important links in the entire logistics management, and the transportation to each branch is the final guarantee for the entire distribution.
The current situation of the transportation link is that the volume of goods is large, the types are many, the distance is close, the outlets are many and scattered, the number of employees is large, and the management is difficult. There are still a series of problems as follows:
1. It is difficult to guarantee the safety of goods in transit. Even with the use of vans, commodity theft or shoddy goods replacement often occur during the goods journey, and even pose safety hazards, which seriously affect the company’s reputation and cause the company to suffer heavy economic losses. The general precaution is to use lead seals for anti-theft management, because ordinary plastics have low anti-counterfeiting performance, and the same lead seals can be easily purchased for replacement, or they can be easily opened without damage; although traditional padlocks are stronger, they can still be easily copied. , Or was pryed open artificially. Commodities lack safety guarantees in transit.
2. The degree of informatization management of transportation vehicles is low. Although most of the vehicles are provided by third-party logistics companies, the vehicles are equipped with GPS positioning systems, but they are not integrated with the company’s information management. For the driving route of the vehicle, where to go, when to leave, when to arrive at the branch, and when to return, it is still a blind spot for monitoring. Therefore, the transportation efficiency of vehicles cannot be improved, which affects the company’s overall distribution efficiency and causes low performance.
3. It is difficult to confirm the responsibility in the process of commodity handover. As the vehicle arrives at the branch, it is difficult for the management personnel to monitor who opened the door and when the door was opened; who closed the door and when the door was closed. It is difficult for management personnel to monitor, and it is difficult to clarify the responsibility for accidents such as loss of goods, which brings inconvenience to management.
2. System function
1. Use highly protectiveRFIDRadio frequency identification technology, through computer, mobile phone, IC card, handheld machine and other unlocking methods, the unlocking command is transmitted to the electronic lock through GPRS, and the door lock is opened and closed. The closing and closing instructions of the door lock are all controlled by the terminal server, which cannot be cracked, and the anti-theft level is high.
2. Whether the delivery vehicle opens and closes the door after arriving at the branch, the three-dimensional coordinates are determined by the on-board GPS and sent back to the server. The server will determine according to the branch address planned in advance and save it on the server for query. If the vehicle does not enter the designated position, the door cannot be opened.
3. The hand-held terminal and authorized IC card held by the person in charge of receiving the goods in each branch can open the car door by swiping the card, or the computer platform, mobile phone WeChat authorized to open the door, the applicant for the authorized IC card identity and SMS secret key held by the person in charge, and the applicant for the verification picture The identity is confirmed by the system server, verified with the system server, and saved on the server for query. Therefore, the identity of the person responsible for opening the door is clarified, and the related responsibilities are also clarified.
4. The time of opening the door of the delivery vehicle to load and unload the goods, as well as the time of closing the door after loading and unloading the goods, are all returned by the system to the system server for storage for query.

Fourth, the system process
*Real-time vehicle location
*Vehicle driving track
*Real-time status of electronic lock
*Electronic lock switch record
*In-transit alarm information
* A variety of unlocking technologies (mobile phone information, computer platform, mobile phone WeChat, IC card, PDA handheld)
Five, product advantages
The characteristics of logistics intelligent electronic locks:
1. Built-in GPS module (support Beidou module), GPRS module, active UHF electronic tag.
2. Using foreign U-BLOX GPS module chip, it can accurately locate the position of the vehicle with an accuracy of <10 meters.
3. Using high-strength plastic molds, the lock body is not easy to be damaged, and an alarm signal will be provided after passive damage, which can be fall-proof, shock-proof, waterproof and dust-proof.
4. High-capacity battery, up to 6200MHA, up to 120 hours of working time
5. GPRS communication mode The terminal automatically enters GPS positioning mode every time it is powered on, using TCP/IP and UDP protocols, and JP808 protocol.
6. The related parameters of the electronic lock can be set remotely.
7. Positioning information, switch status, instant information of electronic lock, etc.
8. Remote authorization unblocking of monitoring center, IC card unblocking mode, handheld unblocking mode, SMS unblocking mode, etc.
9. The monitoring center can regulate the logistics walking route according to the pre-set location range, vehicle overtime, and route. If there is any violation, it will be reported to the monitoring immediately.
