Abstract
The utility model belongs to compressed air purification field, especially relates to a microcomputer control circuit of an adsorption-type dryer. The microcomputer control circuit comprises a CPU and an A-tower start circuit, a B-tower start circuit, a shutdown circuit, a display circuit, a fault reset circuit, an A-tower air-intake circuit, a B-tower air-intake circuit, an A-tower air-exhaust circuit and a B-tower air-exhaust circuit which are connected to the CPU. The display circuit is a liquid crystal display circuit. A touch screen control circuit and a time control circuit which cooperate with the liquid crystal display circuit are also connected to the CPU. According to the microcomputer control circuit of the adsorption-type dryer of the utility model, the liquid crystal display circuit, the touch screen control circuit and the time control circuit which cooperate with each other are adopted, which enables real-time monitoring of a working state, diversified control mode, high-degree automation and stability as well as reduced overall-unit failure rate for the dryer.
Description
Technical field
The utility model belongs to the pressurized air field of purification, relates in particular to a kind of absorption drier microcomputer control circuit.
Background technology
Improving constantly of Along with people's living standard, also increasingly high to the requirement of air utilization and purification, at present, compressed air drier is broadly divided into two kinds of freezing type drier and absorption driers; The water vapor that freezing type drier utilizes refrigeration principle that the pressurized air cooling is isolated wherein carries out drying, and system's air demand of this drier is 100%, but dew point can only reach 2 degrees centigrade to 10 degrees centigrade; In case dew point requires below 0 degree centigrade; Just must adopt absorption drier; And general simple relay or the Single-chip Controlling of adopting of the circuit of traditional absorption drier; Its control mode is single, stability and automaticity are not high, and a large amount of electric elements also make the complete machine failure rate improve greatly simultaneously, and the dryer duty shows incomplete.
Summary of the invention
The utility model is in order to solve defective and the deficiency that above-mentioned prior art exists; Provide a kind of and can monitor dryer duty, control mode variation, automaticity and stable higher in real time, can reduce the absorption drier microcomputer control circuit of complete machine failure rate simultaneously.
The technical scheme of the utility model: a kind of absorption drier microcomputer control circuit; Comprise CPU and be connected A tower start-up circuit, B tower start-up circuit, halt circuit, display circuit, fault reset circuit, A tower air inlet circuit, B tower air inlet circuit, A tower exhaust circuit and the B tower exhaust circuit on the CPU; Said display circuit is a liquid crystal display circuit, also is connected with the touch screen control circuit and the time control circuit that cooperate liquid crystal display circuit on the said CPU.
Preferably, also be connected with pressure control circuit and temperature-control circuit on the said CPU.
The utility model adopts liquid crystal display circuit, touch-screen display and the time control circuit that cooperatively interacts; It is higher to make dryer can monitor its duty, control mode variation, automaticity and stability in real time, has reduced dryer complete machine failure rate simultaneously.
Description of drawings
Fig. 1 is the schematic block circuit diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation, but be not restriction the utility model protection domain.
As shown in Figure 1; A kind of absorption drier microcomputer control circuit; Comprise CPU and be connected A tower start-up circuit, B tower start-up circuit, halt circuit, display circuit, fault reset circuit, A tower air inlet circuit, B tower air inlet circuit, A tower exhaust circuit and the B tower exhaust circuit on the CPU; Display circuit is a liquid crystal display circuit, last touch screen control circuit and the time control circuit that cooperates liquid crystal display circuit that also be connected with of CPU.Last pressure control circuit and the temperature-control circuit of also being connected with of CPU.
The utility model adopts liquid crystal display circuit, touch-screen display and the time control circuit that cooperatively interacts; It is higher to make dryer can monitor its duty, control mode variation, automaticity and stability in real time, has reduced dryer complete machine failure rate simultaneously.
