- the sensor control circuit 341 outputs the sensor control data to the ADC 342 based on the control data of the sensor 35 via the communication block 31, and the sensor data from the sensor 35 converted into digital data by the ADC 342 to the communication block 31. Output.
- the ADC 342 converts the sensor control data from the sensor control circuit 341 into an analog signal and outputs it to the sensor 35, and converts the analog sensor data from the sensor 35 into digital data and outputs it to the sensor control circuit 341.
- the sensor 35 may incorporate an ADC 342.
- Sensor data is transmitted by the communication block 31 at the same timing (signal transmission period) as the transmission data from the actuator control circuit 321.
- communication using the power line can be realized in a situation where power supply from the DC power supply to the power line is continued.
- the detection block 34 and the sensor 35 generally do not have a factor that causes the power supply Vb to fluctuate like the PWM control of the drive block 32 and the actuator 33. Therefore, the current communication timing by the communication block 31 may be controlled as described in the first embodiment. Therefore, also in this embodiment, the current communication between the actuator 3 and the control station communication block 2 does not cause a communication error by exchanging data within the communication period.
- FIG. 17 is a configuration example in which the first embodiment is applied as an electronic control device in which a plurality of ECUs 1a and 1b are connected to a power source 5 by a bus.
- Each ECU 1a, 1b is connected to a power line communication device.
- the power line communication device connected to the ECU 1a includes an actuator 3a having a communication function and a sensor 3b having a communication function on the power line 4a connected to the communication block 2a.
- the power line communication device connected to the ECU 1b has the same configuration.
- the sensor 3b having a communication function is, for example, the actuator 3 having a communication function excluding the drive block 32 and the actuator 33 in FIG.
- communication using the power line can be realized in a situation where power supply from the DC power supply to the power line is continued.
- the actuators 3a and 3c are controlled in the same manner as in the first embodiment. Therefore, the actuator having the communication function and the sensors 3a to 3d having the communication function and the control station communication block 2a The current communication with 2b does not cause a communication error by exchanging data within the communication period.
- communication using a power line can be realized in a situation where power supply from the DC power supply to the power line is continued.
