In this embodiment, utilize the camera to acquire the control picture of concrete in the churn to send the control picture to on-vehicle control module, on-vehicle control module sends the control picture to remote control module, and remote control module shows the control picture, and the staff finds whether need add the admixture in the concrete through the control picture.

Step S102: and receiving an instruction of the remote control module.

In this embodiment, after the staff finds that the concrete needs to be added with the admixture through the monitoring picture, the staff sends an instruction to the vehicle-mounted control module through the remote control module, and the mode of generating the instruction may be to press a control button on the remote control module.

In addition, the concrete state in the mixing drum can be detected by the detection piece, the detection result is obtained and sent to the vehicle-mounted control module, the vehicle-mounted control module sends the detection result to the remote control module, the remote control module judges whether the concrete needs to be added with the admixture or not according to the detection result, if yes, the alarm module is controlled to give an alarm, and for example, when the temperature of the concrete is lower than a certain value, the remote control module judges that the concrete needs to be added with the admixture. Therefore, the staff can also know whether the concrete needs to be added with the additive through the alarm module.

Step S103: and controlling the first valve and the agent control valve to be opened simultaneously, starting timing, and acquiring a first timing value.

In this embodiment, the on-vehicle control module control first relay and second relay are closed simultaneously to control first valve and accuse agent valve and open simultaneously.

Step S104: and judging whether the first timing value reaches a first threshold value, if so, turning to step S105.

In this embodiment, when the first timing value reaches the first threshold value, it indicates that the addition of the external additive is completed.

Step S105: and controlling the first valve and the agent control valve to be closed simultaneously.

In this embodiment, the on-vehicle control module control first relay and second relay break off simultaneously to control first valve and accuse agent valve and close simultaneously.

Further, after the first valve and the agent control valve are controlled to be closed simultaneously, the vehicle-mounted control module controls the third relay and the fourth relay to be closed simultaneously, so that the second valve and the water control valve are controlled to be opened simultaneously, timing is started, and a second timing value is obtained; and judging whether the second timing value reaches a second threshold value, if so, controlling the third relay and the fourth relay to be simultaneously switched off by the vehicle-mounted control module, and controlling the second valve and the water control valve to be simultaneously switched off to finish washing the agent conveying pipe.

After the second valve and the water control valve are controlled to be closed simultaneously, the vehicle-mounted control module controls the fifth relay to be closed, so that the third valve is controlled to be opened, and meanwhile, timing is started to obtain a third timing value; and judging whether the third timing value reaches a third threshold value, if so, controlling the fifth relay to be disconnected by the vehicle-mounted control module, so that the third valve is controlled to be closed, and the pressure and airflow delivery into the agent delivery pipe is finished, so that the water residue in the agent delivery pipe is reduced.

Various changes and specific examples in the device provided by the above embodiment are also applicable to the remote control additive adding method for the mixer truck of the embodiment, and through the foregoing detailed description of the remote control additive adding device for the mixer truck, a person skilled in the art can clearly know the implementation method of the remote control additive adding method for the mixer truck in the embodiment, and for the sake of brevity of the description, details are not described herein again.

The embodiment of the application also provides a mixer truck, which comprises the remote control additive adding device for the mixer truck.

Various changes and specific examples in the device provided by the above embodiment are also applicable to the mixer truck of the embodiment, and through the foregoing detailed description of the device for adding the remote control additive to the mixer truck, a person skilled in the art can clearly know the implementation method of the mixer truck in the embodiment, and for the sake of brevity of the description, detailed description is not provided herein.
