high temperature -20degree to 60degree laser distance meter RS232/485 Connection port measurement accuracy +/-1mm

 

Applications:
1. Road traffic
2. Automotive anti-collision
3. Construction survey and design
4. Levelmaterial level detection
5. Robot arm control
6. Fixed length control of container crane spreader
7. Security monitoring
8. Military applications

Product features

1). Mm level measurement accuracy
2). Continuous detection of a moving object
3). For high temperature/dusty environment
4). Precision-heavy-no need to reflect board
5). With regional test, control system and numeration function

 

 

*Use a target plate to increase the measurement range during daylight or if the target has poor reflection properties.

**In favourable conditions(good target surface properties, room temperature)up to 10m. In unfavourble conditions, such as intense sunshine, poorly reflecting target surface or high temperature variations, the deviation over distances above 10m can increase by ±0.15mm/m.

       2 Operating Steps

 

       2.1 Connect a sensor to the serial port of computer (or other device which have serial ports) and the power port of adapter with special data cable.

 

              2.2 Trigger Measuring

                     2.2.1 Send the command “O” (ASCII) or “0X4F” (HEX) by computer to turn on the sensor. Then the sensor will turn on the laser and prepare for working, and return the data “FF 00 0A 0A 0A 00” to the serial interface.

                     2.2.2 Send the command “O” (ASCII) or “0X4F” (HEX) again to the sensor to start to measure distance. The sensor will return the measured data like “FF XX XX XX XX XX” to the serial interface and turn off the laser when it finished one time measurement.

                     2.2.3 Send the command “U” (ASCII) or “0X55” (HEX) to turn off the sensor.

 

              2.3 Continuous Measuring

                     2.3.1 Send the command “O” (ASCII) or “0X4F” (HEX) by computer to turn on the sensor. Then the sensor will turn on the laser and prepare for working, and return the data “FF 00 0A 0A 0A 00” to the serial interface

                     2.3.2 Send the command “C” (ASCII) or “0X43” (HEX) to the sensor. The sensor will begin to measure continuously after 3 seconds when it got the order, and return the data continuously like “FF XX XX XX XX XX”. If the sensor couldn’t get any available data, it will return “FF 00 0A 0A 0A 00” to the serial interface.

                     2.3.3 Send the command “U” (ASCII) or “0X55” (HEX) to turn off the whole sensor (include both of laser unit and measuring unit).

 

 Input and output

 

       1 Data format for RS232 serial communication

       Baud rate: 9600 bps , Data bits: 8 , Stop bit: 1 , Parity bit: None

 

       2 RS232 input frame format

There is only one byte in every input frame. The user could send different commands to the sensor for different purpose, the functions of command are shown in the following table.

 

HEX	0X4F	0X43	0X55
ASCII(Capital letter)	O	C	U
Functions of command	Power On & Trigger Measuring	Continuous Measuring	Power Off

 

3 RS232 output frame format

There is 6 bytes in every output frame, the frame header is 0XFF, MSB is A, LSB is E. Their orders are shown in this table here.
