Fig. 1 is a schematic structural diagram of a controller for an air dryer according to an embodiment of the present disclosure;
FIG. 2 is a timing control diagram of the timing control circuit.
Detailed Description
In the following, the technical solutions in the embodiments will be clearly and completely described with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present application discloses a controller for an air dryer, which comprises a microprocessor system, a sensor, an execution part, a dryer working state display circuit, a drying tower working state display circuit and a heating rod working state display circuit, wherein the sensor, the execution part, the dryer working state display circuit, the drying tower working state display circuit and the heating rod working state display circuit are in signal connection with the microprocessor system, the execution part comprises an electromagnetic valve and a heating rod, the microprocessor system comprises a system reset circuit, a time sequence control circuit, a signal detection circuit and an alarm circuit, and the controller is used for realizing gas quality detection, displaying the dryer working state in real time, accurately displaying the dryer fault position and giving an alarm. The microprocessor system performs cycle time sequence control on the two electromagnetic valves of the execution component, the control time sequence is shown in fig. 2, so that the working state of the dryer and the working state of the execution component are monitored, and the working states of the dryer A, B tower and the heating rod are displayed in real time through the drying tower working state display circuit and the heating rod working state display circuit.
The working state display circuit of the drying tower displays the working state of the drying tower in real time through the working circuit of the monitoring electromagnetic valve and indicates the working state through the LED lamp, so that information is provided for a user to know the working condition of the dryer.
The heating rod working state display circuit displays the working state of the heating rod of the dryer A, B tower in real time through monitoring the heating rod working circuit and indicates the working state through an LED lamp.
The sensor is responsible for sampling the temperature and the relative humidity value of the finished product gas from the air outlet branch pipe of the dryer and transmitting the temperature and the relative humidity value to the microprocessor system;
the alarm circuit is mainly responsible for sending out alarm signal under the condition that air dryer finished product gas is not up to standard or the dryer breaks down, reminds the user in time to maintain.
Be equipped with 7 groups of pilot lamps on this controller and be used for showing desicator operating condition, include:
1. a power supply indicator lamp (green) is normally on after power is supplied by a power supply, and other conditions are off;
2. the tower A work indicator light (green) is turned on when the tower A is subjected to regeneration conversion, and the conversion is finished;
3. a tower B working indicator light (green) is turned on when the tower B is subjected to regeneration conversion, and the conversion is finished;
4. the working indicator light (green) of the tower A heating rod is turned on when the tower A heating rod works and turned off when the tower A heating rod does not work;
5. the working indicator light (green) of the heating rod of the tower B is turned on when the heating rod of the tower B works and turned off when the heating rod of the tower B does not work;
6. and the white LED lamp is normally on when the detected humidity value does not exceed the limit value. Otherwise, the white light is turned off.
7. And the green LED lamp is normally turned off when the detected humidity value does not exceed the limit value. When the humidity is detected to exceed the limit value, delaying for a certain time, if the humidity value is detected to be still greater than the limit value, the green lamp circularly flashes in a regular way of turning on for 1 second and turning off for 1 second, and an alarm is given.
The controller that this application provided still increases the hardware reset function, when the system detects that software is absorbed in the endless loop, keeps some key data in the microprocessor through system reset circuit to reset microprocessor.
Other embodiments of the present application will be apparent to those skilled in the art from consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of the invention following, in general, the principles of the application and including such departures from the present disclosure as come within known or customary practice within the art to which the invention pertains.
