Information about GPS

Huayu GPS uses geographic information system (GIS), remote sensing (RS), global positioning (GPS), communication, Internet and multimedia technologies to promote the spatial information data industry. GPRS standard vehicle-mounted machine can be applied to almost all GPS application fields at present, such as security, taxis, car rental companies, logistics, long-distance passenger transport, special transport, supervised transport and so on.

I. Basic functions

1, 1 1 information sensor

Open circuit of GPS antenna, short circuit of GPS antenna, backup battery power supply when the main engine is powered off, battery disassembly, emergency button, engine, ACC, high position sensor (effective above 6V) 1, high position sensor 2, low position sensor (effectively grounded) 1, and low position sensor 2.

2. 12 vehicle status

GPS antenna is open, GPS antenna is short-circuited, main engine is powered by backup battery, battery is taken out, engine, ACC, high sensor 1, high sensor 2, low sensor 1, low sensor 2, power failure, fortification.

The center can inquire about these states at any time, and connect the high and low liquid level sensors with brake lights, taillights and instrument switches. To monitor these signals.

3. 10 alarm type

Police robbery, battery removal alarm, GPS antenna open circuit alarm, GPS antenna short circuit alarm, no entry alarm, no exit alarm, overspeed alarm, low speed alarm, GPRS blocking alarm and GPS receiver fault alarm.

4. Two alarm modes

Sms alarm, GPRS alarm

5.64 electronic fences are equipped with alarms for no entry and no crossing.

6, 4 kinds of sensor custom trigger alarm

Realize the low voltage of switch ACC, engine and battery.

7.32 explosion-proof zones are equipped with explosion-proof functions. When entering the explosion-proof area, GSM will automatically turn off, and when leaving the explosion-proof area, GSM will automatically turn on.

8, GPRS/ SMS (command, data) in parallel at the same time.

GPRS is always online, and SMS is always online (GPRS sends and receives SMS online and processes SMS commands), while ensuring speed/flow (GPRS) and reliability (SMS).

9, GPRS/ call parallel at the same time

GPRS handles incoming and outgoing calls online, suspends GPRS transmission after being connected (TCP connection is maintained continuously), and resumes GPRS transmission after hanging up.

10, supports TCP/UDP protocol, and GPRS 3 channels are simultaneously transmitted in parallel.

CP command channel, TCP data channel, UDP data channel, supporting stable transmission of TCP and UDP data channels, with the fastest speed of 1 second/time.

1 1, GPRS automatically redials when dropped, and is always online.

12. The TCP/IP protocol stack used for mobile communication will not generate redundant traffic.

13, 1.6KB command cache, GPRS dropped, telephone call data entered the cache, and recovered immediately after recovery without data loss.

14, TCP and UDP all support compressed transmission, saving traffic.

15, the same SMS /GPRS command and response format, can be transmitted through SMS /GPRS channel at will.

16, a rich command set, which can turn on/off various functions by command and set various parameters in the air.

17, GPRS short message transmission

18, automatic monitoring function, automatic transmission of vehicle position information and status information at regular or scheduled time.

19. Receive and display short messages, and display ordinary short messages or central dispatching commands.

20. Send a fixed short message to the center.

2 1, GPRS interactive short message

The center sends short messages to the terminal, which is especially suitable for dispatching command transmission.

22. At any time, you can cut off the circuit and oil circuit through the monitoring center to ensure safety.

23. Monitoring function: The center orders the vehicle-mounted machine to dial the designated number for monitoring.

24. Incoming or outgoing calls are not allowed.

25. Conditional incoming and outgoing calls in paragraph16.

26, mileage query

27, battery protection function, battery voltage is too low, battery voltage is too high.

28, overvoltage protection, long-term tolerance 100V voltage will not be damaged.

29. All wiring self-checking functions are installed.

30, built-in spare battery, battery voltage is too low, or automatic alarm when the battery is taken out.

Second, the car status display

1, 6 kinds of GPS information: longitude, latitude, direction, speed, time and date.

2. 10 sensor status: engine, ACC, battery removed, spare battery, GPS antenna open circuit, GPS antenna short circuit, high sensor 1, high sensor 2, low sensor 1, low sensor 2.

3. 17 alarm status: police robbery, battery removal alarm, GPS antenna open circuit alarm, GPS antenna short circuit alarm, no entry alarm, no exit alarm, overspeed alarm, GPRS blocking alarm, GPS receiver fault alarm, 8 kinds of custom alarms,
