Compass intelligent vehicle positioning terminal

1.General Description

Compass intelligent vehicle positioning terminal is a new generation of vehicle positioning terminal completely developed by our company. Equipped with vehicle monitoring platform can be realized on the vehicle and ship moving target tracking, trajectory analysis, scheduling, monitoring, anti-theft alarm processing, information dissemination, operation management application service system, statistical analysis in one of the for the moving target, can meet the needs of various industries management monitoring and positioning.

The system is suitable for electric vehicles, logistics vehicles, taxis, bus, long-distance bus, dangerous goods vehicles, shipping and other industries.

2.Function

Query function

2.1.1 Position query

After receiving the position query instruction, the terminal returns the current position information of the vehicle. Location information mainly includes time, longitude, latitude, velocity, azimuth, location sign, vehicle and terminal state, etc..

2.2.2 Parameter state query

After receiving the parameter state query instruction, the terminal returns the current status information of the vehicle. State information mainly includes location information, vehicle status, terminal state, setting parameters, mileage and so on.

Setting function

2.3.1 Timing setting return setting

Setting the designated vehicle according to the setting timing, send the position information to the center through the UDP mode.

2.3.2 Setting the time interval of the location information of the timing return

The time interval including the time interval of the return position information and the return position information during flameout

Time interval of return position information during ignition, terminal factory default 30 seconds.

Time interval of return position information during flameout, terminal factory default 120 seconds.

* When the time interval of the return position information of the flameout is 0 seconds, the time interval of the return position information is transmitted according to the time interval of the ignition, regardless of the ignition or flameout

* If the time interval of the return position information of the flameout is >0 seconds, the terminal will return the time interval according to the return position information of the ignition and flameout.

Note: the minimum time interval of the return position information during ignition is 3 seconds.

Control function:

2.4.1 Remote restart

After the center sends the remote restart command , the terminal will power off automatically then restart it . This command is used for the situation that the communication is normal but otherelse are abnormal, to let the terminal to cut off power then to restart it . In order to make sure the terminal can work normally , the data of mileage meter will be deleted after restarting.

2.4.2 Remote control the oilway

It mainly devides into two parts: to cut the oilway and to recover the oilway.

When the center sends the cut off oilway command , the terminal will cut off the oilway of the vehicle directly , to make it flameout.

When the center sends the recover the oilway command , the terminal will recover the oilway of the vehicle .

2.4.3 The mileage initialized

Setting the mileage of specified vehicle指定车辆的里程数

Mileage: 3 bytes,HEX , Unit: meter. Range:0x000000~0xFFFFFF For example : 0 shows as 0x000000

Alarm function:

Overspeed alarm

After setting the alarm threshold of overspeed , when the driving speed over 10kM/h ,

Over the alarm threshold and stays more than 10 seconds , then it will alarm . The overspeed alarm flag bit is included in the location information.

Alarm way : when it alarms at the first time , it will send a message immediately . And then uploaded according to the timing return time interval.

The way to cancel the alarm: to send the cancel command and the vehicle speed is less than the speed alarm threshold. To send the cancel command and shut off the overspeed alarm .

 

3.Installation

Wiring diagram

Pass through the default interface for the RS232 interface, can take one of the following peripherals:

Temperature detector, oil rod detector, LED advertising screen, camera, scheduling screen, forward and reverse detection.

Transducer can be reused as CAN bus interface:
