Description
Technical field
The present invention relates to a kind of controller, especially a kind of instrument air dryer is used controller.
Background technology
At present, domestic instrument air dryer controller all is only to be made up of hardware circuit basically, simple sequential control function is only arranged, function singleness.Instrument air dryer equipment does not mostly detect, shows the finished product makings amount of exsiccator; Perhaps only be to use test paper change in color reflection finished product makings amount, this detection mode reflection is slow, and testing result is not obvious, can not accurately reflect the quality index of exsiccator finished product gas, and short the replacing frequently of test paper life-span.
So, need a kind of new technical scheme to address the above problem.
Summary of the invention
The objective of the invention is deficiency, provide a kind of multifunctional air drying device to use controller to the prior art existence.
For realizing the foregoing invention purpose, multifunctional air drying device of the present invention can adopt following technical scheme with controller:
A kind of multifunctional air drying device is used controller; Comprise microprocessor, in order to sequential control circuit, data detection circuit, data-carrier store, alerting signal output circuit, the charactron driving circuit of realizing the sequential control function and the charactron display that connects digital tube drive circuit, said sequential control circuit, data detection circuit, alerting signal output circuit and charactron driving circuit; Wherein said data detection circuit is provided with in order to detect the Temperature Humidity Sensor of finished product temperature degree and dew point value, and said charactron display is in order to show detected finished product temperature degree and dew point value.
Preferably, the microprocessor of setting is in order to gather, to handle the quality index of dry air.
Preferably, the microprocessor of setting, is reported to the police through the alarm lamp when dry air is not up to standard in order to judge the quality index of dry air.
Preferably, also be provided with real time clock circuit, microprocessor and real-time timepiece chip recording storage instrument air dryer accumulative total working time, and by the charactron demonstration accumulative total working time.
Compare external warning function, instrument air dryer accumulative total time book storage Presentation Function when multifunctional air drying device of the present invention can be realized sequential control function, the detection of finished product makings amount, Presentation Function, finished product gas quality dissatisfaction with controller with background technology.
Description of drawings
Fig. 1 is the structural representation of multifunctional air drying device of the present invention with controller.
Fig. 2 is the sequential control figure of sequential control circuit.
Embodiment
Below in conjunction with accompanying drawing and embodiment; Further illustrate the present invention; Should understand these embodiments only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
See also shown in Figure 1; For disclosing a kind of multifunctional air drying device, the present invention uses controller; Comprise power circuit, microprocessor, in order to sequential control circuit, data detection circuit, data-carrier store, alerting signal output circuit, real time clock circuit, the charactron driving circuit of realizing the sequential control function and the charactron display that connects digital tube drive circuit, said sequential control circuit, data detection circuit, alerting signal output circuit and charactron driving circuit.
Wherein power circuit is responsible for supplying power to the entire controller system.Sequential control circuit carries out cycle control to two solenoid valves of instrument air dryer, and control mode is as shown in Figure 2.Data detection circuit is responsible for going out from exsiccator temperature, the dew point value of the finished product gas after the gas branch pipe sampling is handled through drying chamber, and it is sent to microprocessor, and microprocessor is presented at temperature, dew point value on the charactron.Warning circuit mainly is responsible under instrument air dryer finished product gas situation not up to standard, sending alerting signal, reminds user's on-call maintenance.
Power circuit at first is divided into two-way with the direct current 110V power supply of input through after the filtering noise reduction process, and one the tunnel reduces to direct current 5V through an isolated power supply chip with it.Another road is reduced to direct current 12V through corresponding conversion with it, and power circuit also has corresponding precautionary measures to power positive cathode reversal connection situation simultaneously.
Sequential control circuit is made up of two identical circuit of structure.The control of two connecting and disconnecting of the circuit electricity conditions is realized by hardware circuit fully.The control output end will adopt measures such as certain afterflow, filtering with the influence to internal circuit of the surge voltage that prevents solenoid valve and moment cause in outage.The power tube that is used to simultaneously drive will have higher withstand voltage properties.
Data detection circuit is gathered out temperature, the dew point value at gas branch pipe place by a Temperature Humidity Sensor.The data that collect are delivered to the single-chip processor i/o mouth with voltage form through shielding line.Such design can guarantee that the data of sensor can normal transmission when receiving outside electromagnetic interference.
Display circuit is made up of two 4 charactrons and chip for driving.The temperature, the dew point value that show finished product gas.And can show the instrument air dryer accumulative total working time through showing conversion keys.These 4 charactron displaying contents have: first, and sign bit ("-": the expression value is less than 0); Three of backs, temperature, dew point value; The accumulative total working time shows, presses the demonstration switching button, and first 4 charactrons show the instrument air dryers fate of accumulative total working times, and second 4 charactron shows hour.
This controller is provided with 3 groups of LED lights, comprising:
Power light (green), power supply power supply back Chang Liang, other situation are gone out;
Green LED lamp, when detected humidity value does not surpass limit value, green light Chang Liang.Otherwise green light extinguishes.
Yellow LED lamp, when detected humidity value did not surpass limit value, amber light often went out.When detecting humidity above limit value, the time-delay regular hour, if detect humidity value still greater than limit value, amber light is with bright rule circulation flicker of going out in 1 second in 1 second, alarm.
Real time clock circuit is through clock chip and microcontroller record instrument air dryer accumulative total working time.
This controller also increases the hardware reset function, when system detects software and is absorbed in endless loop, preserves some critical datas in the microprocessor through hardware reset circuit, and microprocessor is resetted.
