Grating special controller

The present invention discloses a grating special controller. The controller comprises an on-off input collection module, a nixie tube display module, a four-way button input module, a four-way output control module and a conversion module, and the on-off input collection module, the nixie tube display module, the four-way button input module, the four-way output control module and the conversion module are connected with a main control circuit module, wherein the conversion module is connected with the four-way button input module. There are many control modes to select, such as manual operation, timing, the liquid level difference, the remote control and the like, and the traditional control mode realizes the control modes mentioned above, and is high in cost, complex in circuit, bad in reliability and difficult to maintain, etc. The controller can be realized through connecting the switching and the protection with the program built in a single-chip microcomputer. The controller can realize a linkage function through the liquid level difference meters after and before the grids, when the liquid level difference after and before the grids is larger than a certain value, the liquid level difference meters output signals to the controller, and the controller works when detecting the signals until the signals disappear. The function is difficult to realize through the traditional control mode.
