The invention has the beneficial effects as follows: the present invention calculates storage module through side-play amount and calculates the deviate that stores measurement; Utilize this deviate can improve the accuracy of measurement data greatly, increased the demonstration and the operation precision of measurement data greatly, can calibrate in the time of arbitrarily; Improve the dirigibility of debugging; Because without circuit such as potentiometers, so the complicacy of circuit, hardware cost, fault probability can reduce, and the functional reliability of controller is improved; The present invention reduces debugging difficulty and debugging step as long as fixing signal value of input just can be calibrated.
Description of drawings
Further explain below in conjunction with accompanying drawing and embodiment:
Fig. 1 is the application synoptic diagram of high-voltage switch controller;
Fig. 2 is the block diagram of system of an embodiment of the present invention.
Embodiment
With reference to Fig. 2; The high-voltage switch controller of automatic calibration function of the present invention; Comprise main control unit 1 and the input input circuit 2 that is connected with main control unit 1, switching input module 3, switching value output module 4; It is characterized in that being provided with in the said main control unit 1 the side-play amount calculating storage module 5 that is used to calculate and store detection signal actual value and measured value deviation size; Main control unit 1 is connected with and is used to control the automatic calibration operation control input end 6 that side-play amount is calculated storage module work; Side-play amount is calculated storage module 5 and is calculated the measured value through the appointment fixed amount of input input circuit input, and measured value and the actual value of specifying fixed amount obtain side-play amount after relatively.
In order to realize convenient power supply, on-off controller also comprises power supply managing module 7, and the input end of power supply managing module 7 is connected with voltage transformer (VT) on being arranged on power circuit, and output terminal is connected with main control unit 1.In addition; In order to make function of the present invention more complete reliable; High-voltage switch controller preferably includes display circuit module 8, keyboard load module 9, external protocol communication interface module 10, RCI module 11 etc., and the input end of above-mentioned module or output terminal are connected with main control unit 1 respectively.Utilize display circuit module 8 users can check the various duties of on-off controller; Utilize 9 of keyboard load modules to control and to adjust, utilize external protocol communication interface module 10, RCI module 11 can realize remote monitoring and control function on-off controller.
The present invention is when realizing automatic calibration function, and at first to preassigned fixed signal value of high-voltage switch controller input, main control unit calculates off-set value under the cooperation of side-play amount calculating storage module 5.The automatic calibration of each input quantity (like Ia, Ib, Ic, Io, PT1, PT2 etc.) can utilize said method to realize.Be that example is described calibration steps of the present invention below with Ia.
As shown in Figure 1, from the fixed amount that the input end of analog signal Ia of high-voltage switch controller imports an appointment, then utilize automatic calibration operation control input end to main control unit input " calibration operation automatically " order.This moment, main control unit judged that the analog quantity of input is preassigned fixed amount, and after main control unit detects the order input of " calibration operation automatically " again simultaneously, main control unit will get into automatic calibration procedure and carry out automatic calibration process.Main control unit draws the good AD respective value of curve with the algorithm computation that the Ia that imports is directed against the high-voltage switch gear special characteristic; And then calculate the AD value of acquired signal after level and smooth according to the algorithm of high-voltage switch gear special characteristic; Cooperate the actual fixed value calculating of the corresponding standard of preassigned fixed signal just to obtain a side-play amount again; Just this coefficient is preserved then, and withdrawed from automatic calibration procedure and get into normal supervisory routine.Input end of analog signal Ia with high-voltage switch controller during normal process cooperates the automatic coefficient of coming out of calibrating, and what obtain at last is exactly the actual value of the input end of analog signal Ia of actual high-voltage on-off controller.
