Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of automatic control of vacuum pumps, and particularly relates to a vacuum pump switch automatic integrated control method and system, a vacuum pump control terminal in vehicle production, a receiving user input program storage medium, a computer program product stored on a computer readable medium, and an application. BACKGROUND

[0002] The C01 line vacuum pump belongs to a perennial running state and is not closed, and functions to supply vacuum pressure to a mechanical hand. The vacuum pump functions to generate vacuum pressure after being started, and belongs to a running state at all times when the equipment is being established. Unless power is cut off, the vacuum pump can be stopped. Long-time running can reduce the service life of the vacuum pump. Due to the management of energy by the company after daily production ends, the compressed air of the equipment needs to be closed. Under this condition, the prior art cannot stop the vacuum pump at the same time when the compressed air is closed, nor can the vacuum pump be automatically started after the compressed air is opened. The indirect automatic opening condition of the vacuum pump cannot be met.

[0003] Through the above analysis, the problems and defects of the prior art are as follows: (1) the vacuum pump operation switch is relatively hidden, and no one closes it or cuts off power to close it; (2) the vacuum pump is always running, which can affect the service life of the equipment; and (3) the switch automatic integrated function is not realized.

[0004] The significance of solving the above problems and defects is that the present application realizes the automatic integrated function of the switch by transmitting the electrical signal of the PLC controller to automatically stop the vacuum pump from running when the equipment is not in use, and to automatically run the vacuum pump when the equipment is started.
