The switching of the standby oxyhydrogen generator groups is respectively replaced to the abnormal normal oxyhydrogen generators in sequence, when the main controller monitors that a certain standby oxyhydrogen generator cannot work normally, the main controller continues to monitor the standby oxyhydrogen generators with other numbers in sequence until the normal standby oxyhydrogen generator is monitored, the automatic switching module switches the normal standby oxyhydrogen generator to the abnormal normal oxyhydrogen generator, and the rest standby oxyhydrogen generators are still in a standby state.
The main control system can set parameters and control operation of all the oxyhydrogen generators, can monitor all the operation parameters of all the oxyhydrogen generators in real time, immediately collect and analyze and judge abnormal types when the common oxyhydrogen generators are abnormal, upload abnormal information, and simultaneously automatically control the opening of a valve to switch the normal standby oxyhydrogen generator to the abnormal common oxyhydrogen generator, thereby ensuring normal continuous supply of oxyhydrogen cutting gas and reducing the oxyhydrogen cutting accident rate. Illustrating: if the 1 # common oxyhydrogen generator (A1) is abnormal, the automatic switching of the standby oxyhydrogen generator is determined according to the abnormal type, and then in the process of automatically switching the normal 1 # standby oxyhydrogen generator (B1), the 1 # standby oxyhydrogen generator in the oxyhydrogen gas special control device is switched to the automatic control valve of the 1 # common oxyhydrogen generator to be opened, and at the moment, the oxyhydrogen gas supply pipeline is as follows: the automatic control valve (V11) of the No. 1 standby oxyhydrogen generator is switched to the automatic control valve (V11) of the No. 1 common oxyhydrogen generator in the No. 1 standby oxyhydrogen generator (B1), the input end (D1) of the No. 1 standby oxyhydrogen generator, the automatic control valve of the No. 1 common oxyhydrogen generator in the oxyhydrogen special control device, and the oxyhydrogen gas is output to the No. 1 cutting gun (E1).
