1. Scheme application and description
(1) The status of the enterprise. In view of the current status of coal land transportation, the transportation volume is large, the transportation distance is long, and theft or shoddy phenomenon occurs during the transportation, which seriously affects the reputation of the transportation enterprise and even causes the enterprise to suffer heavy economic losses. The traditional The management methods are mainly driver contract constraints, road inspections, reward and punishment measures, and persuasive education, with little actual effect. Using high-tech management methods to make it inevitable, the introduction of RFID technology is undoubtedly an advanced management method, and it is also a concrete manifestation of advanced experience at home and abroad.
(2) The basic principle of RFID electronic label technology. It is a non-contact automatic identification technology that automatically recognizes targets and obtains relevant data. It is easy to operate on-site. The tag digital ID is unique, and can intelligently read and write and communicate, realize computer management. The vehicle label realizes the automatic identification management of the vehicle from the origin to the destination; the sealed label realizes the management of the sealing and unsealing of the goods.
(3) Label features Fast reading and writing speed, low price, high data security, and easy to use.
(4) The application of the vehicle label is applied with an electronic seal at the origin, and the vehicle information, quantity, coal grade and other information are written in the seal, and the electronic seal information is read at the destination to confirm whether it is the origin To seal the information. The unique code of the electronic signature corresponds to the number of vehicle information recorded, and is compared through computer software.
(5) When the application of electronic signatures originates, seal the vehicle around the enclosed area and read the data. This is the process of sealing; when arriving at the destination, the data is also read and the tags are removed. This is the process of unsealing. , All data is stored in the handheld reader and uploaded regularly to realize platform software management.
(6) Main hardware components. Vehicle label management is mainly composed of vehicle windshield tags, origin and destination long-distance card reading facilities (instructions omitted); electronic signature management is mainly composed of electronic signatures, card issuers, and handheld machine reading Card device and system software composition.
(7) Introduction to software functions and processes
Schematic diagram of the overall business process:
1. Authority management: It is to control the user authority of the electronic seal, and no one can write information on the electronic seal, which is convenient for controlling the electronic seal. 2. Sealing management: the special person at the origin place seals the trucks loaded with coal, and writes some information into the electronic seal at the same time to ensure that each vehicle is in the sealed state before being put on the road. Take a picture and save it. 3. Unseal management: When the coal transportation vehicle arrives at the destination, the integrity of the electronic seal is first checked, and then the information of each electronic seal is collected, and the photos are kept on file. If there is no problem, you can enter the unloading area. 4. Download information: The handheld computer reads the electronic signature information of the coal truck and insures it, and uploads it to the control center at the same time.
5. Information management: The control center centrally manages the collection information of the origin and destination and keeps a complete information record. 6. Inquiry and comparison: compare the sealing information of the origin and the unsealing information of the destination to ensure There is no error in the electronic signature information of the two places. 7. Commonly used functions: The entire process of transporting vehicle information can be temporarily controlled, including the sealing information of the origin, destination inspection information and comparison results.
2. Product introduction (1), electronic signature:
Used to seal the packaged goods, use steel wire (or plastic tape) to tighten, and it can only be tightened and cannot be pulled out. It needs to be cut with a special tool to unblock it, and it is one-time use, and its reliability is high. The seal has an ID number with a unique password and a non-contact identification chip, which can ensure the uniqueness and non-replicability of the seal number. The seal has a unique code defined by the company independently, which has high security and replaces traditional lead seals. The many drawbacks of.
(Two), handheld card reader (handheld machine):
The handheld is a machine used to record tag information at the origin, and records the entered information in the handheld, and at the same time transmits the entered information to the control center through wired or wireless transmission. The hand-held card reader at the destination is used to read the information in the electronic signature, save it and upload it to the control center, and compare it with the input information of the origin, and has the function of taking pictures, and the information before sealing and unsealing Status photo retention card (data collection terminal is used for business operations such as sealing, patrol inspection, uploading, etc.) detailed technical indicators:
