Coal Yard Vehicle Management Plan
This program provides feasible solutions for the overall planning of the coal yard vehicle management system, and provides references for project initiation, development, and implementation.
Chapter 1 Introduction
I. Overview
A large number of coal transportation vehicles enter and exit the coal yard every day, requiring procedures such as parking, registration, and weighing. The operator manually enters the data into the computer. This is not only time-consuming, but also has a large error rate. In addition, it is easy to cause artificial fraud. Enterprises cause a lot of economic losses.
The coal yard vehicle management system combines RFID technology, electronic truck scale technology, communication technology, automatic control technology, database technology and computer network technology to automatically record the license plate number, weight information, time information, etc. of vehicles equipped with electronic tags and write them The mainframe database can effectively eliminate human error, prevent over-balance blockage, cheating, etc., ensure the accuracy of original data collection, and reduce economic losses.
Two, system goals
This solution implements intelligent management for all vehicles entering the coal yard, and requires each vehicle that enters the coal yard to be assigned a special coal transportation label, which stores the name of the coal vehicle owner, vehicle weight, unit, and time of entry and exit And other information. When the coal truck is weighed by the truck scale, the reader reads the tag on the truck and transmits the information in the tag to the host, and at the same time instructs the electronic scale to transmit the vehicle weight information. The coal yard management system can automatically measure the coal weight through the information when the coal truck enters and exits the yard, and calls the data in the host database at any time to query or form a report, so as to avoid human error and prevent over-balance blockage, cheating, etc. To ensure the accuracy of original data collection and reduce economic losses.

Among them, the automatic weighing system of automobile weighing is mainly composed of weight sensors and weighing display instruments. It mainly completes the functions of weight data collection and communication with the upper computer. The computer monitoring and management part is composed of computers, printers, radio frequency identification systems, controllers, and barriers. , Vehicle detector, camera, video card, mainly complete weighing monitoring, printing scales, identification, generating various summary statistical reports and comprehensive query functions.
System diagram
2.1. Auto weighing system for automobile weighing
The system has all the functions of GM truck scales, and can automatically weigh, record and print the results of coal vehicles entering the truck scale without being on duty; when coal vehicles enter the truck scale for weighing and measurement At the same time, the system can input information such as the number, tag card number, license plate, unit, driver, etc. of coal transportation vehicles, and can generate reports and print at the same time.
2.2. Computer monitoring and management system
The computer monitoring and management part is composed of computers, printers, radio frequency identification systems, controllers, barriers, vehicle detectors, cameras, and video cards. The radio frequency identification system consists of a reader, an antenna and a tag. The tag is attached to the windshield of the car. When the reader reads the tag, the camera takes a photo of the vehicle, and the tag card number, vehicle The picture and the vehicle’s information are transmitted to the host and stored in the host database. The appendix is the radio frequency identification system (optional).
Three, the system process
The coal yard vehicle management process is as follows:
3.1. Admission registration
The coal yard registration office first registers the vehicles entering the coal yard, and allots them a special coal transportation label, and then saves the card number, vehicle license plate number, vehicle owner’s name, entry time and entry location related information in the host database middle.
3.2. Invoicing
Only customers who have been issued special labels for coal transportation can go to the coal yard invoicing office to issue an invoice to purchase coal.
3.3. Empty truck weighing
After the customer issues the ticket, the coal truck can be driven into the truck scale channel for weighing. The vehicle detector installed at the crossing senses the entry of the car, and transmits the signal to the front barrier and signal light. The barrier is immediately closed and the signal light turns red. Prompt the driver to drive slowly, and at the same time ask the weighing instrument and reader to start working. After the tag on the coal truck is read by the reader, the reader antenna transmits the information of the car to the host, and instructs the electronic scale to start transmitting the weight information of the car. At the same time, the camera monitors whether the car is parked at the designated position and captures the image. When the host receives the card number and weight information, it accurately records and backs up the information, and then sends out instructions to open the barriers, and the coal truck drives into the coal yard to load coal.
3.4, coal loading
After the empty coal truck has weighed, it can drive into the coal yard for coal loading.
3.5. Loading coal and weighing
After the coal truck is loaded with coal, it needs to enter the truck scale again for weighing. The vehicle detector installed at the crossing senses the entry of the car and transmits the signal to the barrier and signal light in front. The barrier is immediately closed and the signal light turns red to indicate The driver drove slowly, and at the same time asked the weighing instrument and reader to start working. After the tag on the coal truck is read by the reader, the reader antenna transmits the information of the car to the host, and instructs the electronic scale to start transmitting the weight information of the car. At the same time, the camera monitors whether the car is parked at the designated position and captures the image. When the host receives the card number and weight information, it accurately records and backs up the information, and then issues an instruction to open the barriers, and the coal truck drives into the coal yard to issue tickets.
3.6 Billing
After coal trucks are loaded with coal, they need to go to the ticketing office again to issue an invoice. The ticketing office will check whether the information on the two weighings of the coal truck is consistent. This information includes whether the special coal label card number is consistent, whether the vehicle owner is consistent, whether the brand number is consistent, etc. When all the information is consistent, the billing office will automatically calculate the net weight of the coal transported according to the management system to issue the bill, and collect the special coal transport label.
3.7 Appearance
Finally, the coal truck can drive out of the coal yard with a bill and pass the inspection by the guard.
Four, system characteristics
real time monitoring
All information in the four operation processes of vehicle queue management, sampling, weighing and skinning are fed back to the monitoring center host in real time, and the management personnel can understand the status of each work process in real time through the monitoring software system. For example, there are vehicles that jump in line at the sampling site, the vehicles cannot be positioned during weighing and skinning, and the vehicle number cannot be read, etc., can all be understood in the monitoring center.
In order to ensure the uninterrupted work of the coal yard, the automatic metering system adopts two working modes: automatic mode and manual mode. Under normal circumstances, the automatic method is adopted. When some hardware equipment in the system fails and cannot work in automatic mode, manual operation can be used to ensure the normal production of the coal yard. When the hardware equipment is repaired, switch to Automatic way. The manual method is a backup method.
Compared with the previous coal yard vehicle management, the use of RFID technology for coal yard vehicle management has the following advantages:

The computer displays the weight of the cargo carried by this 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 and eliminate the phenomenon of favoritism: one card for one car, the electronic label is pasted on the windshield of the car, and the weight of the weighbridge each time 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 all truck scales (weighbridges) in the coal yard, which can easily measure the weight of coal trucks when they are empty and full, and understand the transportation in real time. The actual weight of the cargo loaded on the coal car, thereby greatly improving the work efficiency of the enterprise.
4. Protect the safety of this area and prevent illegal vehicles from intruding: This system can be integrated with the parking lot management system. Only vehicles with legally authorized electronic tags can enter the coal yard for coal loading and its weighing area, thereby improving the safety of this area.
5. Avoid human operation loopholes. Due to the method of automatically reading data, all over-balanced vehicles are automatically counted by the computer, eliminating manual intervention, automatically recording data, and automatically verifying and releasing.
