Abstract

A control device and method for starting and stopping an oxyhydrogen decarbonizing machine belongs to the technical field of oxyhydrogen decarbonizing machine application. The problem that an oxyhydrogen decarbonizing machine control system fails in distinguishing due to the fact that a method of judging an automobile engine operation state by detecting vacuum suction of an automobile air inlet pipe is not general is solved. A digital-to-analog (DA) converting circuit of the device is used for collecting a voltage signal of an automobile storage battery which is the automobile storage battery of an engine to be cleaned. The DA converting circuit transmits a converted simulation voltage signal to a programmable logic controller (PLC), and the PLC compares the collected voltage signal with an inner preset voltage threshold and outputs a control signal to the oxyhydrogen decarbonizing machine to control starting or stopping of the oxyhydrogen decarbonizing machine. The control method includes that the inner voltage threshold of the PLC is first set and then compared with the collected voltage signal, and the operation state of the oxyhydrogen decarbonizing machine is controlled. The control device and method is used for controlling the oxyhydrogen decarbonizing machine.

Example Embodiment

[0024] Specific implementation mode 1: the following combination figure 1 with Figure 4 To explain this embodiment, the start-stop control device of the hydrogen-oxygen decarbonizer described in this embodiment includes a DA conversion circuit 1 and a PLC controller 2.
[0025] The DA conversion circuit 1 is used to collect the voltage signal of the car battery. The car battery is the battery of the car whose engine is to be cleaned. The DA conversion circuit 1 transmits the converted analog voltage signal to the PLC controller 2, and the PLC controller 2 will collect the After the voltage signal is compared with the internal preset voltage threshold, a control signal is output to the hydrogen-oxygen carbon removal machine to control the start or stop of the hydrogen-oxygen carbon removal machine.
[0026] In this embodiment, the PLC controller 2 first performs PID calculations on the collected analog voltage signals, converts them into digital signals and sends them to the designated address for use, and then the PLC controller 2 calls the digital voltage signals and voltages in the designated address. The threshold value is compared, and the hydrogen and oxygen decarbonizer is not allowed to work if the requirements are not met.

Example Embodiment

[0027] Specific implementation manner 2: the following combination figure 1 This embodiment will be described. This embodiment will further explain the first embodiment. This embodiment also includes a buzzer 3, and the alarm signal input end of the buzzer 3 is connected to the sound alarm signal output end of the PLC controller 2.
[0028] When the PLC controller 2 detects that the voltage signal of the car battery is lower than the voltage threshold, it controls the hydrogen-oxygen carbon removal machine to stop and sends an alarm signal to the buzzer 3 at the same time.

Example Embodiment

[0029] Specific implementation manner three: the following combination figure 1 This embodiment will be described. This embodiment will further explain the first or second embodiment. This embodiment also includes an alarm lamp 4, and the alarm signal input end of the alarm lamp 4 is connected to the light alarm signal output end of the PLC controller 2.
[0030] The PLC controller 2 can control the hydrogen and oxygen decarbonizer to stop when detecting that the voltage signal of the car battery is lower than the voltage threshold, and send an alarm signal to the buzzer 3 and the alarm lamp 4 at the same time.
[0031] In this embodiment, if the operation result of the PLC controller 2 is found to deviate from the set value during the operation of the hydrogen-oxygen carbon removal machine, it will immediately shut down and issue an audible and visual alarm signal.
