Ventilation device for ship repair

A ventilation device for ship repair comprises a controller, the controller is connected with a temperature sensor and a pressure sensor through an AD converter, the temperature sensor is used for detecting temperature parameters of an application environment, and the pressure sensor is used for detecting pressure parameters of the application environment; the controller is correspondingly connected with the multiple air blowers through the driver and the interlocking assembly so as to input fresh air, the driver is used for transmitting trigger signals to the air blowers so that the air blowers can enter the working state, and the interlocking assembly is used for preventing the disorder phenomenon between the multiple air blowers. The controller is connected with an upper computer through a wireless transceiver so as to achieve remote control of the upper computer to the controller, the controller is further connected with a timer and a radiator, the timer is used for recording the working time of the air b
