The figure is as follows: 1. elevator motion module, 2, transmission light curtain module, 3, receipt light curtain module, 4, analog circuit amplification module, 5, signal detection module, 6, MCU signal judgment module.

Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.

The utility model discloses an embodiment relates to an elevator control system with self-checking function, as shown in fig. 1, including elevator motion module 1, transmission light curtain module 2 and receipt light curtain module 3, elevator motion module 1 link to each other with transmission light curtain module 2, transmission light curtain module 2 links to each other with receipt light curtain module 3, receipt light curtain module 3 link to each other with analog circuit amplification module 4, analog circuit amplification module 4 links to each other with signal detection module 5, signal detection module 5 links to each other with MCU signal judgment module 6, MCU signal judgment module 6 links to each other with elevator motion module 1.

Thirty-two signal lamps are arranged in the receiving light curtain module 3, and the thirty-two signal lamps receive signals from top to bottom in sequence and input the signals into the analog circuit amplification module 4.

An analog amplifying circuit is arranged in the analog circuit amplifying module 4, and a waveform detecting module is arranged in the signal detecting module 5.

When the elevator motion module 1 is in operation, the transmitting light curtain module 2 can emit signals, the receiving light curtain module 3 receives the signals and reads light pipe signals of thirty-two signal lamps, then the signals are input into the analog circuit amplification module 4, the analog circuit amplification module 4 amplifies the signals, then the signals pass through the signal detection module 5, so that the signals are converted into a oscillogram, the oscillogram is input into the MCU signal judgment module 6, and the comparison is carried out to determine whether to stop the elevator.
