Principle one

The Global Positioning System (GPS) is a satellite navigation and positioning system established by the United States. Through this system, users can achieve all-weather, continuous, real-time three-dimensional navigation positioning and speed measurement on a global scale. In addition, the system uses the system. The user can also perform high-precision time transfer and high-precision precision positioning.

In real life, GPS positioning is mainly used for remote real-time positioning monitoring of moving people, pets, vehicles and equipment. GPS positioning is a positioning technology that combines GPS technology, wireless communication technology (GSM/GPRS/CDMA), image processing technology and GIS technology, and can mainly achieve the following functions:

1. Tracking and positioning

The monitoring center can monitor the real-time location, driving direction, and speed of all controlled vehicles 24 hours a day, so as to know the status of the vehicle in the most timely manner.

2. Track playback

The monitoring center can replay the history of the vehicle's history and track record in the custom period at any time within 60 days. (Depending on the situation, optional track DVD recording service)

3. Alarm (Report)

3.1, Speeding alarm: When the vehicle speed exceeds the preset speed of the monitoring center, it reports to the monitoring center in time.

3.2, Area Alarm (Electronic Fence): The monitoring center sets the area range. If the vehicle exceeds or enters a preset area, it will give a corresponding alarm to the monitoring and dispatching center.

3.3, Parking report: The dispatch center can generate reports on the historical parking records of vehicles in text form, describing the parking location, time and driving time of the vehicles, and printing them.

3.4. Emergency alarm: In case of emergency (such as being robbed), please immediately press the emergency alarm button to alert the supervision center. The supervision center will immediately know that you are in an emergency and your location. After verification, enter the police situation to help you get out of danger. (Note: Once the emergency alarm button is activated, the device will immediately close the call function, but the SMS function is normal)

3.5, undervoltage alarm, when the car battery voltage is too low, the car host will automatically alarm to the monitoring center, the monitoring center attendant to remind users to charge the vehicle in time.

3.6. Trimming alarm. When the main battery of the vehicle is damaged or cannot be powered, the built-in backup battery can keep the product working and send a trimming alarm to the monitoring center.

4. Map making function

According to the viewing needs, customers can add and modify custom map lines to better serve the company's operations

5. Mileage statistics

The system makes use of GPS vehicle terminal's driving record function and GIS geographic system principle to calculate the mileage of vehicles, and can generate reports and print them.

6. Vehicle Information Management

An easy-to-use management platform provides settings for information such as vehicles, drivers, and vehicle pictures to facilitate the dispatch of personnel.

7. SMS notification function

Various alarm or status information of the controlled vehicle will be sent to the manager's mobile phone when necessary so as to grasp the important status information of the vehicle at any time.

8. Vehicle remote control

The monitoring center can remotely cut off the fuel and power off the vehicle and lock the vehicle at any time.

9. Car phone

The car phone can be dialed and called like an ordinary mobile phone. The dispatch center can set the remote permission for this phone, that is, the incoming call restriction, the outgoing call restriction, and only the specified number of phone calls.

10. Fuel consumption testing

Real-time monitoring of changes in fuel consumption of vehicles and production of oil level change reports or oil volume charts for historical periods, and intuitively reflecting normal consumption, abnormal consumption of fuel, and insufficient refueling quantity to achieve a high level of fuel consumption management and prevent adverse events. happened. (Need to match the oil sensor)

11. Vehicle scheduling

The dispatcher determines whether to schedule the vehicle or draw a schedule on the map. The GPS system automatically issues a dispatch command to all vehicles in the vehicle or within the specified range. The dispatched vehicle responds to the dispatch center in time to determine the execution of the dispatch command. The GPS system can also perform monthly statistics on the number of successful dispatches per vehicle.
