(2) reliability height
Electronics pcb board process stabilizing: at first adopt SMT automatic chip mounting technology, reduce artificial paster failure rate; Secondly the electronic circuit board of two secondary modules adopts three anti-treatment process means and methods, can moistureproof anti-salt fog mildew-resistant.
(3) electromagnetic compatibility
In two secondary modules, the design principle of FPGA is adopted in master chip control, can directly realize the Filtering Processing to input signal.In the building control system, can run into interference signal inevitably, various burrs can cause the false triggering of motor, and FPGA is owing to be that multithreading is worked simultaneously, and according to the characteristics of signal, takes different filtering modes, has improved the reliability of system.
(4) volume is little, and is easy for installation, attractive in appearance
Two secondary modules adopt concentrates integrated control element, has abandoned the complete components and parts of relevant secondary in original wiring in complete wiring, as relay, and electric bell etc.; In case, have only CPS and two secondary modules so.Volume no matter promotes a lot than Vintage Product on mounting means and the aesthetic measure on the whole.
Product adopts modular construction, realizes fault self-checking.Binding post employing and components and parts are corresponded manner one by one, very convenient engineering maintenance personnel's periodic maintenance and fault inquiry.
Two secondary modules of control of the present utility model and protection switch electrical equipment; also have energy-conservation, saving material advantage, efficiently solve conventional motors control and protect the product discrete component many, the wiring complexity; the debugging trouble is difficult to realize problems such as system automation and network management.Electrical design, production and use are standardized and medelling more, strengthened equipment such as all kinds of water pumps, blower fan, air-conditioning use in the civil buildings fail safe, reliability, economy greatly.
