Description

Periodic switch control device of electric power supply

Technical field

The present invention relates to a kind of control device, particularly a kind of periodic switch control device of electric power supply.

Background technology

During the computing machine new product development, need checking main frame to be measured whether can also normally move, and when main frame to be measured produces fault, also want to note down the number of times of test through behind the repeated open and close machine.Yet present power supply switch controller can only once be controlled the power supply of one group of main frame to be measured, and can not retain main frame to be measured and produce the state of fault when machine, is unfavorable for that the research staff finds and deals with problems.

Summary of the invention

In view of the above problems, the object of the present invention is to provide a kind of periodic switch control device of electric power supply, its power supply that can control at least one group of main frame to be measured simultaneously carries out the switch of several times, and can retain the state of main frame generation fault to be measured when machine.

For reaching above-mentioned purpose, periodic switch control device of electric power supply provided by the invention, be used to control the periodic switch of main frame to be measured, it comprises an operation control interface, a single-chip microcomputer, a control relay circuit and a signal detection and logic control circuit; This single-chip microcomputer is connected respectively with this operation control interface, this control relay circuit, this keyboard signal detecting and logic control circuit, and this main frame to be measured is connected between this control relay circuit and detecting of this keyboard signal and the logic control circuit.

This operation control interface connects this single-chip microcomputer, is used for setting and monitoring this periodic switch control device of electric power supply; This main frame to be measured is opened or closed to this single-chip microcomputer first output terminal output On/Off signal by this control relay circuit; After opening, this main frame to be measured will export a test signal to signal detection and logic control circuit; This signal detection and logic control circuit judge according to this test signal thereby whether this main frame startup to be measured successfully exports the feedback end that a high level or a low level signal are given this single-chip microcomputer; The signal that this single-chip microcomputer receives according to its feedback end and from the setting message at operation control interface, whether decision stops or continuing test, and whether successful test mode sends this operation to controls the interface with should main frame startup to be measured.

In addition, have several interconnect interfaces between this control relay circuit and this signal detection and the logic control circuit, it can insert at least one main frame to be measured, some groups of separate connection relations can be set to control this four main frames to be measured respectively between this single-chip microcomputer and this control relay circuit, this logic control circuit.After this main frame to be measured starts failure, first output terminal of this single-chip microcomputer will no longer be exported and open or shutdown signal, the state in the time of so can keeping this main frame to be measured and start failure.

Embodiment

Consult shown in Figure 1, it is the circuit block diagram of energy supply periodic controller for opening and closing of the present invention, this energy supply periodic controller for opening and closing comprises operation control interface 100, single-chip microcomputer 200, control relay circuit 300, main frame to be measured 400 and signal detection and the logic control circuit 500 that is together in series, and this signal detection and logic control circuit 500 also connect this single-chip microcomputer 200.In present embodiment, this operation control interface 100 is a personal computer, being used to set time, this main frame 400 to be measured of opening or closing this main frame 400 to be measured starts the test procedure of operation, the number of times that need test altogether etc., and is sent to this single-chip microcomputer 200 by the RS232 interface; The first output terminal OUT1 of this single-chip microcomputer 200, this control relay circuit 300, this main frame 400 to be measured are connected in series successively, in present embodiment, this control relay circuit 300 is a solid-state relay control circuit, this first output terminal OUT1 output start signal PWRCC_X_ON or shutdown signal PWRCC_X_OFF give this control relay circuit 300,300 power supplys of opening or closing this main frame 400 to be measured of this control relay circuit.

This main frame 400 to be measured connects this signal detection and logic control circuit 500 by USB interface, in present embodiment, this signal detection and logic control circuit 500 are keyboard signal detecting and logic control circuit, please cooperate consult shown in Figure 2, it comprises a keyboard signal simulator 510 of series connection successively, one first impact damper 520 or one second impact damper 530 and a logic be decision circuitry 540 relatively, this keyboard signal simulator 510 receives the test signal PWRCC_X_IN of this main frame 400 to be measured, and respectively by this first, two impact dampers 520,530 transmit signal PWRCc_X_CAP, PWRCC_X_NUM gives relatively decision circuitry 540 of this logic, this logic comparison decision circuitry 540 according to from the selection signal PWRCC_X_SEL of the 3rd output terminal OUT3 of this single-chip microcomputer 200 to select this binary signal PWRCC_X_CAP, a PWRCC_X_NUM wherein signal is a comparison signal, judge in view of the above whether successful this main frame 400 to be measured starts, then output signal PWRCC_X_H is to the feedback end FB of this single-chip microcomputer 200 if start successfully, and output signal PWRCC_X_L gives this feedback end FB if startup is failed then.

This feedback end FB receives this signal PWRCC_X_L, then the first output terminal OUT1 of this single-chip microcomputer 200 no longer exports and opens or shutdown signal PWRCC_X_ON/OFF gives this control relay circuit 300, thereby main frame to be measured 400 will be parked in and start the state of failure when machine; When feedback end FB receives this signal PWRCC_X_H, then the first output terminal OUT1 of this single-chip microcomputer 200 will transmit a shutdown signal PWRCC_X_OFF and give this control relay circuit 300, then the second output terminal OUT2 of this single-chip microcomputer 200 will transmit a reset signal PWRCC_X_CLR and give relatively decision circuitry 540 of this logic, and then export start signal PWRCC_X_ON by the first output terminal OUT1 after the default time interval; After number of times that the feedback end FB of this single-chip microcomputer 200 receives this signal PWRCC_X_H reached default number of times, these single-chip microcomputer 200 first output terminals no longer repeated to export any signal, promptly stop this main frame 400 to be measured is started test.

Have several interconnect interfaces between this control relay circuit 300 and this signal detection and the logic control circuit 500, it can insert at least one main frame 400 to be measured, some groups of separate connection relations can be set to connect these four main frames 400 to be measured respectively between this single-chip microcomputer 200 and this control relay circuit 300, this signal detection logic control circuit 500, can control these four main frames 400 to be measured simultaneously respectively thus.In addition, after this main frame 400 to be measured starts failure, the first output terminal OUT1 of this single-chip microcomputer 200 will no longer export start signal PWRCC_X_ON or shutdown signal PWRCC_X_OFF, so can keep this main frame to be measured 400 and start the state when machine after the failure.

Certainly be outstanding essence emphasis of the present invention, thus above-mentioned be not for implement of the present invention all, related custom circuit partly omits to some extent and does not do to give unnecessary details, and can reproduce the present invention fully with reference to present embodiment.
