1. System overview
In recent years, many companies have encountered many problems such as few records, missing records and private vehicles in the transportation of finished products and vehicle management. More and more arrogant people have not only caused a serious loss of corporate assets and income, but also formed work habits that are extremely unfavorable to long-term development due to inadequate management measures, which have seriously affected the management and management of the company. Economic benefits.
For this reason, the release of a complete set of transportation vehicles and truck scale weighing systems with RFID identification technology has become imminent. It should not only make vehicle management information-based, but the most important thing is that it must be able to achieve real leak-proof requirements on the basis of radio frequency identification technology, infrared alignment technology, video surveillance and other technologies.
2. System composition
“Kaitai Unattended Intelligent Weighing System”, including RFID radio frequency card system, barriers, traffic lights, LED large-screen display system, video monitoring system, remote printing system; centralized storage at the back end, and network printers in each weighing room Remote output of weighing orders; RFID radio frequency long-distance card reading and writing system and road access control system automatically collect information and data of each transportation vehicle, conduct anti-cheating inspections, and automatically intercept vehicles if the weighing process is not completed. The system is also equipped with modules such as order purchasing, sales, weighing, quality inspection, settlement, and financial interface.

Fourth, the system process
(1) When the car enters the car weighing channel, the vehicle detection beam installed at the crossing immediately senses that there is a car entering, and transmits the signal to the barriers and traffic lights in front. The barriers are immediately closed and the signal lights turn red. , Prompts the driver to drive slowly, and at the same time requires the weighing instrument and reader to start working.
(2) When the electronic tag on the vehicle enters the reading range of the reader, the information of the vehicle will be transmitted to the host through the antenna-the reader. After verifying the legality of the “vehicle identity”, the control signal light will send out the correct Signal, instruct the electronic scale to start transmitting weight information; at the same time, the camera is used to monitor whether the vehicle is parked at the designated position and to capture the image of the vehicle. If the vehicle is parked normally, the weighing signal can be accepted by the computer.
(3) When the host receives the ID number (corresponding to an identification code) and weight information, it accurately records and backs up the relevant information; then, the system sends an instruction to the controller, and the relay on the controller acts to open the barrier, and at the same time The signal traffic light turns green. The vehicle can drive away from the truck scale channel.
(4) The host computer transmits the vehicle-related information to the data management center, and they finally complete the data processing and statistical tasks, and then send the data to the designated place through the local area network.
Five, system advantages
1. Information collection automation
The weighing data output by the platform scale and the electronic tag card number installed on the vehicle are processed by related equipment and transmitted to the computer. The computer immediately displays the weight of the cargo carried by the car and stores it in the computer’s database. Users can perform operations such as querying, summarizing, and printing according to their needs, thereby realizing information collection automation.
2. Strengthen management to prevent favoritism and fraud
One card for one car, the electronic label is pasted on the windshield of the car, which has the function of tamper-proof. Once the electronic tag is torn off the glass, the chip inside is damaged and cannot be used again. Each time the weighing scale weighs, it strictly corresponds to one card and one car. Cooperate with the camera’s image capture function to ensure that the entire system data is foolproof and accurate.
3. Establish corporate image, improve work efficiency, and reduce operating costs
The system performs computer automated network management on the weighing of all cars in the entire unit, which can easily measure the car weight when the car is empty and full, and understand the actual weight of the goods loaded in the car in real time, thereby greatly improving the work efficiency of the enterprise.
4. Protect the safety of this area and prevent illegal vehicles from entering
This system can be integrated with the parking lot management system, and only vehicles with legal electronic tags can enter the car cargo weighing area, thereby improving the safety of this area. In terms of refueling tank trucks, it is particularly important.
