Description
Technical field
The utility model relates to electric valve technical field, particularly relates to a kind of electric controller of electric valve.
Background technique
In prior art, the electric controller of electric valve divides three modules, installs in the mode superposed, and is outwards followed successively by power module, LCD MODULE, main control module from inner, belong to independently unit separately, be connected with datawire by fastening piece between three unit.
Wherein, power module is provided with transformation device and power interface, external 380V ac power supply, adopts AC/DC conversion, and its effect is stabilized power supply required when the ac power supply of input being transformed into main control module work.
Main control module comprises cpu chip, data-interface, and its effect is processing control signals, and completes the Signal transmissions between cpu chip and each module.Data-interface can not only provide data for LCD MODULE, power supply required when LCD MODULE also can be provided to work.
LCD MODULE comprises liquid crystal display, data processing chip, data-interface, external signal reciever, valve position tutorial light, and this module plays two effects: 1, engineering staff can judge the operation conditions of valve according to the data that liquid crystal display shows; 2, also can accept external signal by external signal reciever, complete the control to valve event state.
But prior art exists following shortcoming: 1, cost is higher, not only consume a lot of electrotechnical apparatus, increase wiring and mounting cost, and when user's in-site installation, need the more time to debug; 2, because power panel, liquid crystal display panel, data processing plate belong to separate unit, need a lot of connection set and wiring between three, circuit is quite complicated, not only takies the inner space of electric controller, and easily break down in data transmission procedure, system responses is very slow; 3, inconvenience maintenance, in three unit, any one goes wrong, all will remove and keep in repair, and need to operate very carefully in maintenance process, in case produce new problem, add operation easier, also need the longer time to debug after a repair, considerably increase the difficulty of maintenance.
Model utility content
The purpose of this utility model is to provide a kind of electric controller of electric valve, can reduce costs, and be easy to debugging, and working efficiency has had obvious lifting.
The purpose of this utility model is achieved in that a kind of electric controller of electric valve, comprise shell, and being fixed on power module, LCD MODULE, the main control module of shell inner cavity, described power module, LCD MODULE, main control module concentrate formation one piece of control panel; Described power module comprises transformation device, power interface, and described transformation device adopts AC/DC conversion; Described LCD MODULE comprises liquid crystal display, data processing chip, is used for showing the valve position tutorial light of valve opening and closing state; Described main control module comprises cpu chip, external signal reciever; All described components and parts are all connected by circuit.
The beneficial effect that the utility model produces is: compared with prior art, cost of material reduces greatly, does not need a lot of electronic parts and components, and the difficulty of adjustment and installation reduces, and reduces recruitment cost; Wiring is simplified, and the space taken is little; Compact structure, is convenient to maintenance, and is not easy to break down.
For the ease of transmission data, realize the control to valve, described control panel is provided with I/O serial data interface.
In order to optimizing structure design, Appropriate application inner space and do not cause structural interference, described control panel is fixedly connected on shell inner cavity by screw, its edge and described shell inner cavity suitable.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is scheme of installation of the present utility model.
In figure, 1 shell, 2 control panels, 21 power modules, 211 power interfaces, 212 transformation devices, 22 main control modules, 221CPU chip, 222 external signal reciever, 223 I/O serial data interfaces, 23 LCD MODULEs, 231 liquid crystal displays, 232 data processing chips, 233 valve position tutorial light, 3 screws.
Embodiment
As shown in Figure 1-2, a kind of electric controller of electric valve, comprise shell 1, and be fixed on power module 21, LCD MODULE 23, the main control module 22 of shell 1 inner chamber, wherein power module 21, LCD MODULE 23, main control module 22 concentrate formation one piece of control panel 2;
Above-mentioned power module 21 comprises transformation device 212, power interface 211, and transformation device 212 adopts AC/DC to convert;
Above-mentioned LCD MODULE 23 comprises liquid crystal display 231, data processing chip 232, is used for showing the valve position tutorial light 233 of valve opening and closing state;
Above-mentioned main control module 22 comprises cpu chip 221, external signal reciever 222;
All above-mentioned components and parts are all connected by circuit.
Above-mentioned control panel 2 is provided with I/O serial data interface 223.
Above-mentioned control panel 2 is fixedly connected on shell 1 inner chamber by screw 3, its edge and shell 1 inner chamber suitable.
During work, input power enters transformation device 212 from power interface 211, and 380V Ac is converted to 24V direct current, power supply required when providing monoblock control panel 2 to work, especially valve position tutorial light 233 and liquid crystal display 231; After external signal Receiver 222 receives the control signal from outside, Signal transmissions is processed to cpu chip 221, then the signal after process is delivered to I/O serial data interface 223, by I/O serial data interface 223, control signal is reached actuator, thus realize the control to valve; I/O serial data interface 223 can also receive valve position feedback signal, after cpu chip 221 processes, output to liquid crystal display 231 after again feedback signal being processed by data processing chip 232, liquid crystal display 231 display according to this just technician observe valve running state.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all any amendment, on an equal basis replacement and improvement etc. done within spirit of the present utility model and principle, all should drop within protection domain of the present utility model.
