I. Introduction
GPS and wireless communication technologies have gradually developed and improved, and their applications in steel, coal, and other industries are particularly prominent. The monitoring system not only provides a certain degree of protection for people in safe production, but also ensures the safe transportation of high-quality steel.
2. Demand analysis
Take coal transportation as an example. In recent years, coal companies have frequently experienced various accidents. The safe transportation of high-quality coal mines to the destination is an important link to avoid huge property losses to the country and the people. The frequent loss of high-quality coal mines in coal mining companies has led to urgent requirements for the transportation monitoring system. The location update of transportation personnel, the reporting of dynamic data of transportation vehicles, and the real-time notification of management personnel all show the particularity and importance of coal transportation system business. . According to these business requirements, Xiamen Lansi Communication Co., Ltd. has developed a coal mine transportation monitoring system based on GPRS/CDMA network, which can solve the comprehensive application problems of image capture, real-time vehicle positioning and monitoring, remote monitoring, data transmission, voice communication, etc. .
Three, system overview
This system integrates many advanced technologies such as GPS global satellite positioning technology, GIS geographic information technology, GPRS/CDMA mobile communication technology and Internet interconnection technology. The GPS coal transportation monitoring system is developed on the basis of the existing mobile or China Unicom mobile network. .
Through this system, all target vehicles within the coverage of GPRS/CDMA network can be monitored remotely. The GPS real-time positioning information, image capture, various alarm data (speed alarm, stay overtime alarm, etc.) of the monitored target, and driving status information data are uploaded to the monitoring center through the GPRS/CDMA network by the LZ8713A GPS terminal. Under special circumstances, the monitoring center can remotely cut off the oil and power, and turn off the coal mine transportation vehicles. The system has the function of real-time dynamic monitoring of all-weather and all-route vehicles, and is mainly used for positioning monitoring, image capture, data alarm, dispatching and other purposes of coal mine transportation vehicles. The coal mine transportation monitoring system has played an important role in the transportation of high-quality coal mines:
1. Real-time positioning and monitoring of the location of transportation vehicles
2. The alarm function is perfect, and the monitoring center can take emergency measures as soon as possible
3. Image capture to let the monitoring center understand the situation on the spot
4. The network structure is simple, and the installation is quick and easy

2. Alarm
Anti-robbery alarm: for emergency button, when necessary, press the button for more than 3 seconds, the center will receive a special alarm signal, and take the initiative to upload the picture of the car situation at this time to the center for corresponding processing.
Speed alarm
The vehicle speed alarm speed value can be set in the terminal, or the alarm speed value can be remotely configured by the center. When the vehicle speed exceeds or falls below the set value, a speed alarm will be generated and uploaded to the monitoring center actively. For example, if the monitoring center sets the vehicle speed value not to be lower than 20, the alarm will be issued when the vehicle speed is lower than 20 horses and the image will be captured, and the center can automatically pop up the vehicle alarm information.
Monitoring center platform (satellite map + alarm information pops up automatically):
Cross-border alarm: also known as electronic enclosure, the device automatically detects a designated area, and will report location information when entering or leaving the area according to the set area range conditions. This area can be set by the terminal itself or the center.
Offset route alarm: When the vehicle leaves the set driving route, the terminal reminds the driver that it has deviated from the driving route through the dispatch terminal, and at the same time sends the deviation route alarm information to the center at a certain time interval.
Parking alarm: The center issues instructions to set the time value of the parking alarm. When the parking time exceeds the set time value, a parking overtime alarm is generated.
3. Image capture
Support camera capture from different angles. The user can install a camera in the car according to the actual situation. Support remote remote control real-time capture, remote control capture at any time as needed to understand the situation in the car.
4. Call function
Vehicle answering the call: The center sends a “call” command to the designated terminal, and the driver manually answers through the handle or car phone to realize the two-way call function; dial to realize the voice call. (Optional car phone)
5. Remote control
Cut off oil and power: The center can send “close oil circuit” and “restore oil circuit” to control the opening and closing of the vehicle’s oil outlet circuit, so as to control the driving of the vehicle.
