TABLE 1
Remarking: in the table, 0 indicates that the pressure switch of the corresponding column is not operated, and 1 indicates that the pressure switch of the corresponding column is operated.
It is known from experience that the columns a and B of the double column dryer are switched every 2 minutes, so 2 minutes is a cycle. When the single chip microcomputer 1 judges the double-tower pressure signal, whether action exists every 2 minutes is used as a judgment basis.
Interpretation of table 1: because the towers A and B work alternately, one tower is in a working state and the other tower is in a non-working state under the normal operation state. The pressure switch corresponding to 1 in the table is actuated, namely the corresponding tower is in a working state.
If the tower A does not work and the tower B does work in the adjacent previous period, the tower A should work and the tower B should not work after the adjacent next period is alternated, namely the tower A is changed from 01 to 10 and the corresponding double towers normally run; when changing from 01 to 00, it indicates that the A tower has a fault first, and does not change when the 1 state should be changed; on the premise that the tower A does not take over the work, the corresponding tower B can normally continue to work, and at the moment, the tower B also enters a non-working state, so that the fault of the double towers is judged; when the state is changed from 1 to 01, the A tower is in failure, and the A tower is not changed, and the state is changed to 1, and the B tower continues to work, so that the A tower is determined to be in failure, and the B tower is determined to be normal.

Still further, as shown in fig. 1, the present embodiment further includes an indicator light 6, and the single chip microcomputer 1 outputs a display control signal to the indicator light 6 according to the determination result of the double-tower operating state.
The indicator light 6 may include a tower indicator light a and a tower indicator light B, and may be set to indicate that the working state is normal with the green second flashing state respectively, and indicate a certain drying tower fault under the normally-on state.
Still further, as shown in fig. 1, the present embodiment further includes a 4G module 7, and the single chip microcomputer 1 transmits the result of determining the operating state of the double towers to the monitoring terminal through the 4G module 7.
