测距原理

TOF是Time of Flight的缩写，即飞行时间。具体是指通过周期性的向外发出红外光调制波，当调制波遇到被测目标后反射，然后用传感器接收从被测目标反射回来的调制波。通过测量调制波往返的相位差，可得到飞行时间，从而计算出传感器与物体目标之间的相对距离。示意图如下所示。

Modbus Protocol

  • The single-point TOF laser ranging sensor adopts the industrial standard Modbus protocol. Modbus communication commands are divided into two types: read commands and write commands.
    • Read Command (0x03): Read data from the corresponding register.
    • Write Command (0x06): Write data to the corresponding register.
  • The specific read and write formats are shown in the following tables:
    • Data Frame Sent by the Host Computer

    • Example: Reading Measurement Distance
      • Send Command: 50 03 00 34 00 01 c8 45
      • Received Data: 50 03 02 07 0B 06 7F
      • Data Parsing:
        • Send: 0x50 is the Modbus ID (default), 0x03 is the command number (read command), 0x34 is the register address (measurement data), 0x01 is the read length (one digit), 0xc8 0x45 are the CRC check digits.
        • Receive: 0x50 is the Modbus ID (default), 0x03 is the command number (read command), 0x02 is the data length (two digits), 0x07 0x0B is the measurement data (0x070B corresponds to 1803 in decimal, and the measurement distance is 18036mm), 0x06 0x7F are the CRC check digits.
