Description

Mahjong machine fault-tolerant control method

Technical Field

The invention relates to a fault-tolerant control method for a mahjong machine.

Background

The existing mahjong machine mechanism is controlled by a positioning sensor signal to work. For example, the central lifting mechanism controls the lifting motor to stop at an upper position and a lower position (also called initial position) respectively by an upper sensor signal and a lower sensor signal; the square mahjong rising mechanism controls a mahjong rising motor to stop at an initial position according to signals of an initial position sensor; the mechanism with two stop positions is called a double-stop-position mechanism, and the mechanism with only one stop position is called a single-stop-position mechanism. The four-direction mahjong lifting mechanism of the eight-port machine has one more middle position than that of the four-port machine, which is also called a double-stop position mechanism, and a horizontal pushing machine head of the four-port machine only has a machine head opening position and a machine head closing position (also called an initial position), and is also a double-stop position mechanism.

The steps of the central lifting mechanism of the mahjong machine for completing the lifting work are as follows:

after the lifting key is pressed, the lifting motor is started, and after the upper sensor has a signal, the lifting motor stops at the upper position and opens the large-disc card inlet; after the cards are pushed into the large plate, the lifting key is pressed, the lifting motor is started, and after the lower sensor has a signal, the lifting motor stops the lower position, and the card inlet of the large plate is closed.

The mahjong machine four-direction tile lifting mechanism completes the tile lifting work steps as follows:

after the lifting mechanism finishes the card feeding work, the square card lifting motor is started, and after the initial sensors of each card lifting motor have signals, the initial positions of the card lifting motors of each card lifting motor are respectively stopped, so that the card lifting work is finished.

Once the mahjong machine is affected with damp or used for a long time, the fault of poor contact and occasional open circuit of each sensor line is easy to occur, and after each sensor is occasionally opened, the mechanism can continuously search the stop position signal, so that the next step of work cannot be carried out.

The above situation can be seen that the signals of each sensor are important and unique signals of the stop positions of each mechanism of the mahjong machine, and once the signals are lost, the mahjong machine cannot normally complete corresponding work.
