The utility model belongs to the field of compressed air purification, and particularly relates to a microcomputer control system for a compression and heat adsorption type dryer. The microcomputer control system comprises a CPU (Central Processing Unit), and a tower A start-up circuit, a tower B start-up circuit, a shutdown circuit, a display circuit, a failure reset circuit and an intermediate relay which are connected on the CPU; and a touch screen control circuit, a digital quantity module and a temperature control module are further connected on the CPU, and a plurality of analog quantity modules are connected on the digital quantity module. According to the microcomputer control system for the compression and heat adsorption type dryer, the CPU 224XP, the temperature control module EM231 RTU, the digital quantity module EM223, the analog quantity modules EM231 and the Kunlun on-state touch screen display are adopted, so that the microcomputer control system has the advantages of diversification in control manner, higher degree of automation and stability, and low failure rate of the whole dryer.
Description
Technical field
The utility model belongs to the compressed air field of purification, relates in particular to a kind of heat of compression absorption drier microcomputer control system.
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 steam that freezing type drier utilizes refrigeration principle that the compressed 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 traditional heat of compression 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 fault rate improve greatly simultaneously.
Summary of the invention
The utility model provides a kind of control mode variation, automaticity and stability higher, simultaneously the low heat of compression absorption drier microcomputer control system of complete machine fault rate in order to solve defective and the deficiency that above-mentioned prior art exists.
The technical scheme of the utility model: a kind of heat of compression absorption drier microcomputer control system; Comprise CPU and be connected A tower start-up circuit, B tower start-up circuit, halt circuit, display circuit, fault reset circuit and the auxiliary reclay on the CPU; Also be connected with touch screen control circuit, digital module and temperature control module on the said CPU, be connected with some analog modules on the said digital module.
Preferably, also be connected with anxious control circuit and the near/long-range commutation circuit of stopping on the said CPU.
Preferably, said digital module is EM223, and said temperature control module is EM231RTU, and said analog quantity control module is EM231.
Preferably, said analog quantity control module quantity is two.
The utility model has adopted CPU224XP, EM231 RTU thermal module, EM223 digital module, EM231 analog module and the Kunlun on-state touch-screen display; Make that its control mode variation, automaticity and stability are higher, the complete machine fault rate is low simultaneously.
Description of drawings
Fig. 1 is the schematic block circuit diagram of the utility model.
The specific 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 heat of compression absorption drier microcomputer control system; Comprise CPU and be connected A tower start-up circuit, B tower start-up circuit, halt circuit, display circuit, fault reset circuit and the auxiliary reclay on the CPU; Last touch screen control circuit, digital module and the temperature control module of also being connected with of CPU is connected with two analog modules on the digital module.Last also being connected with of CPU suddenly stopped control circuit and near/long-range commutation circuit.Digital module is EM223, and said temperature control module is EM231RTU, and the analog quantity control module is EM231.
The utility model has adopted CPU224XP, EM231 RTU thermal module, EM223 digital module, EM231 analog module and the Kunlun on-state touch-screen display; Make that its control mode variation, automaticity and stability are higher, the complete machine fault rate is low simultaneously.
