Scheme:
4. 1, real-time monitoring
The monitoring center carries out single-point, fixed-time and fixed-distance monitoring on coal transport vehicles; And support coal vehicles to upload location information according to the active monitoring parameters configured by the monitoring center.
4.2, real-time location query
The monitoring center can query the current vehicle position information in real time.
4.3, electronic fence
The system can divide coal loading area, coal unloading area and special area (such as gas station) into different types of electronic fences.
4.3. 1, electronic fence monitoring management
The system automatically realizes the perfect monitoring and management of vehicles on the coal transportation line. When the vehicle drives out of the electronic fence at the loading point, the whole process of monitoring and dispatching management will be implemented. When the vehicle deviates from the designated driving route or stops overtime, the monitoring center will receive the corresponding alarm prompt, and automatically send SMS and TTS voice to the vehicle terminal to remind the driver (if you please deliver the goods to the designated destination in time). At the same time, the system will automatically capture pictures and upload them to the monitoring center. When the vehicle leaves the unloading point (the destination of the goods), the system cannot monitor and manage the vehicle as mentioned above.
4.4, image capture and automatic upload
1, supports remote capture, and can capture remotely at any time as needed to understand the real-time situation of vehicles.
2. Support users to trigger GPS terminal snapshots according to different event types. For example, when there is an alarm such as illegal parking timeout, it will take the initiative to capture the image and transmit it to the monitoring center. At present, the system can provide three kinds of triggering events, namely, illegal parking overtime, off-lane driving and robbery alarm. And in order to meet the follow-up needs of users, the signal sensing harness is specially reserved to provide other event-triggered snapshots. At the same time, in order to save the communication cost as much as possible, this terminal supports the event-triggered snapshot switch button and the event-triggered snapshot real-time upload picture switch button.
4.5, TTS voice broadcast function
The terminal adopts the most advanced TTS voice technology at present, which can broadcast the text information sent by the center in the form of voice in time. When the driver displays text information on the operation screen, the driver can understand the information sent by TTS voice center, which can greatly reduce the hidden danger of driving safety. Vehicle alarm information (such as speeding alarm) can also remind the driver in the form of TTS voice while operating the buzzer and short message on the screen (for example, when the vehicle is speeding, broadcast "You are speeding, please slow down!" )。
4.6, track playback function
The platform server can record the historical trajectory of the vehicle, and managers can view the trajectory playback at any time in front of the vehicle. Therefore, the monitoring personnel do not need to pay attention to the driving situation of the vehicle in real time, but can check the previous driving trajectory of the vehicle through trajectory playback in their leisure time.
4.7, call function
1. Vehicle answers the phone: the center sends a "call" command to the designated terminal, and the driver manually answers it through the call handle to realize the call function between the two parties; Dial to realize voice call.
2. Vehicle call: the driver dials through the call handle to realize the call between the two parties.
3. Call restriction: The terminal can only answer or dial the preset telephone number.
4.8, SMS function
Multiple short messages (car trouble, traffic jam, large passenger flow, accident, etc.). ) is built into the terminal for the driver to choose and send according to the situation, and provide the operation information to the center in time; The center can inquire the information and location of the vehicles involved through the monitoring system, and release the disposal information to the driver. Users can set and modify the content of short messages at will.
4.9, mileage statistics function
1. The terminal can save the accumulated mileage in meters since the terminal was powered on. Users can check the mileage of vehicles at any time.
2. The terminal can calculate the mileage according to the ACC status of the vehicle and the latitude and longitude of the GPS, that is, when the vehicle is ignited, the mileage is counted according to the GPS and uploaded to the central server.
4. 10, real-time speed display function
The driver's operation screen displays the timely vehicle speed, which reduces the maintenance cost of vehicle sensors and speed meters. Vehicle speed can be collected by GPS vehicle speed and vehicle speed sensor.
4. 1 1, parking overtime alarm
The center gives instructions to set the time value of parking alarm. When the parking time exceeds the time value of the parking alarm, it will generate a long parking alarm and actively upload the captured vehicle status picture to the center.
4. 12, off-course alarm
When the vehicle deviates from the set driving route, the terminal reminds the driver that it has deviated from the driving route through the dispatching terminal, and at the same time sends an alarm message of deviation to the center at regular intervals.
4. 13, robbery alarm
Provide panic button. If necessary, press the button for more than 3 seconds, the center will receive a special alarm signal, and take the initiative to upload the captured car condition pictures to the center for corresponding processing.
4. 14, overspeed alarm
The speed value of overspeed alarm can be set in the vehicle terminal or remotely configured by the center. When the vehicle speed exceeds the set value for a specified time (the overspeed time can be set), an overspeed alarm will be generated.
4. 15, GPS antenna short circuit and open circuit alarm.
The vehicle terminal monitors the GPS reception in real time, but when the GPS antenna is open or short-circuited (such as man-made damage), the terminal will send the GPS antenna status to the center for alarm.
4. 16, user-defined alarm
Six custom alarms are reserved in the vehicle terminal, and images can be uploaded through the custom alarms. Alarms are triggered at high and low levels.
4. 17, system reporting function
The report function of the system is mainly divided into two parts: a, alarm statistics; B, driving records.
Alarm statistics include: emergency alarm statistics, overspeed alarm statistics, parking overtime statistics and off-line statistics. Driving records include: mileage statistics, working hours statistics, vehicle online statistics, etc. The above data are stored in the database of the platform server for a long time, and can be queried and counted at any time.
Chapter V System Advantages
5. 1. Advantages of using GPS in transportation enterprises
1, the safety of transport vehicles and drivers has been guaranteed to a higher degree;
2. Enterprises can know the running status information of transport vehicles and the whole process of coal delivery to the destination in real time and actively;
3. Through reasonable dispatching, enterprises can fully understand vehicle information and improve economic benefits and management level.
