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.

Description

technical field [0001] The invention relates to a start-stop control device and a control method for a hydrogen-oxygen decarbonizer, and belongs to the application technical field of a hydrogen-oxygen decarbonizer. Background technique [0002] Hydroxygen carbon removal machine is a machine for cleaning carbon deposits in automobile engines. At present, there are some safety hazards in the operation of domestic hydrogen-oxygen decarbonizers used to clean automobile engines. The main reason is that the hydrogen-oxygen decarbonizers cannot automatically stop working after the engine is turned off. For example, when the car is accidentally turned off during the decarbonization process, It will cause the hydrogen and oxygen produced by the hydrogen and oxygen decarbonizer to accumulate in the car intake pipe, and when the car is started again, it will damage the car intake pipe and cause a safety hazard. [0003] The general way to solve this problem in the prior art is to dete...
