Description

Control protection switch numbers intelligent controlling device
Technical field
The utility model relates to a kind of electrical equipment control protective device, particularly a kind of Control protection switch numbers intelligent controlling device.
Background technology
At present, low voltage control protective device, mainly motor monitored and protect, the multiple situations such as the overload occurred in motor operation course, phase shortage, imbalance, underload, electric leakage, external fault are protected, and can need to control according to the scene such as fire-fighting, building; Existing control protective unit usually adopt discrete component as: signal lamp, button, electric bell, auxiliary reclay, the time relay, control transformer, universal seclector, wire etc. are assembled; There is the deficiency that components and parts are many, secondary distribution is loaded down with trivial details, failure rate is high, because distribution adopts AC220/AC380V voltage, in humidity and hot environment, the fault of line short also easily occurs.
Utility model content
In order to solve the deficiency of above-mentioned existing control protective unit, the utility model provides a kind of Control protection switch numbers intelligent controlling device.
The utility model solves the technical scheme that its technical matters adopts: Control protection switch numbers intelligent controlling device, comprise, for input signal being carried out analog-to-digital input signal analog-to-digital conversion module, be used for the Control protection switch control processor of signal control treatment, be used for the eeprom memory module that digital signal stores, the RS485 data exchange module being used for exchanges data, be used for the numeral method module shown, the control key-press module being used for man-machine interactive operation, be used for the output signal module that control signal exports;
Described Control protection switch control processor 2 connects input signal analog-to-digital conversion module, eeprom memory module, RS485 data exchange module, numeral method module respectively, controls key-press module, output signal module.
The external input signal that described input signal analog-to-digital conversion module receives includes, A/B/C threephase current transformer signal and transformer alternating sampled signal.
The output signal of described output signal module includes, electronic trip unit signal, short circuit return signal, overload return signal, operation return signal and stopping return signal.
The beneficial effect that the utility model has is: adopt Digital Circuit Control mode to instead of traditional mechanical analogue control mode, adopt integrated circuit, electronics pcb board technique, SMT automatic pasting technique technology, moistureproof, high temperature resistant, greatly reduce traditional secondary line trouble spot, reliability is high simultaneously; Easy to assembly, debugging is simple, reduces cost of labor, and complete casing reduces, and greatly reduces material cost; Except A/B/C three-phase supply port for exchanging 380V I/O, control coil port is that except alternating current 220V input, other all of the port outlets are below low pressure 36V or passive signal, installation personnel to field wiring, debug fast safer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Parts and numbering in figure:
1-input signal analog-to-digital conversion module; 2-Control protection switch control processor; 3-numeral method module; 4-EEPROM memory module; 5-RS485 data exchange module; 6-controls key-press module 7-and outputs signal module.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, Control protection switch numbers intelligent controlling device, comprise, for input signal being carried out analog-to-digital input signal analog-to-digital conversion module 1, be used for the Control protection switch control processor 2 of signal control treatment, be used for the eeprom memory module 4 that digital signal stores, the RS485 data exchange module 5 being used for exchanges data, be used for the numeral method module 3 shown, the control key-press module 6 being used for man-machine interactive operation, be used for the output signal module 7 that control signal exports;
Described Control protection switch control processor 2 connects input signal analog-to-digital conversion module 1, eeprom memory module 4, RS485 data exchange module 5, numeral method module 3 respectively, controls key-press module 6, output signal module 7.
The external input signal that described input signal analog-to-digital conversion module 1 receives includes, A/B/C threephase current transformer signal and transformer alternating sampled signal.
The output signal of described output signal module 7 includes, electronic trip unit signal, short circuit return signal, overload return signal, operation return signal and stopping return signal.
Implementation process: input signal analog-to-digital conversion module 1 receives the simulating signal of A/B/C threephase current transformer signal and transformer alternating signal, be converted to digital signal and export Control protection switch control processor 2 to, man-machine interaction sends instruction by controlling key-press module 6 to Control protection switch control processor 2; Numeral method module 3 shows real-time parameter; Control protection switch control processor 2 is undertaken the correlation parameter in data handling procedure to preserve and call by outside eeprom memory module 4; by the communication that RS485 data exchange module 5 carries out each other, realize exchanges data each other.Control protection switch control processor 2 carries out independent and multi-thread control by the electronic trip unit of multithreading to output signal module 7 of microprocessing, controls electric terminal such as the electronics of water pump, blower fan and threads off.
Electronics thread off: when system be short-circuited or fault time; Control protection switch control processor 2 can send instruction timely makes electronic trip unit disconnect; cut off the interchange AC220V signal of input transformer simultaneously; at this moment the A/B/C three-phase alternating current 380V signal no-output of input control protection switch digital intelligent controller; thus be disconnected the operation of appliance terminal as water pump, blower fan, serve protection terminal device be burned when short circuit or fault situation.
In building control system, inevitably run into undesired signal, various burrs can cause the false triggering of the equipment such as motor, the microprocessing of this device have employed that multithreading works simultaneously, and according to the different characteristics of signal, take different filtering modes, substantially increase the reliability and stability of whole device.
The utility model tool adopts Digital Circuit Control mode to instead of traditional mechanical analogue control mode, adopt integrated circuit, electronics pcb board technique, SMT automatic pasting technique technology, moistureproof, high temperature resistant, greatly reduce traditional secondary line trouble spot, reliability is high simultaneously; Easy to assembly, debugging is simple, reduces cost of labor, and complete casing reduces, and greatly reduces material cost; Except A/B/C three-phase supply port is for exchanging 380V I/O, control coil port is that outside alternating current 220V input, other all of the port outlets are below low pressure 36V or passive signal, installation personnel to field wiring, debug fast safer.
