Abstract
The utility model belongs to the electric automation control field, and mainly solves the problem that most microcomputers do not have the function of timing for switch-on and switch-off. The utility model is composed of a timing control circuit, an executive device and an on-card battery or an additional power supply. The utility model is mainly characterized in that when the microcomputer is in the switch-off state, the power for the main circuit on the card is supplied by the on-card battery or the additional power, so that the microcomputer can work normally and time. When the timing attains to the switch-on time, the executive device switches on the power supply of the microcomputer. The utility model is mainly used for controlling the timing for automatic switch-on and switch-off of the microcomputer.
Description
The utility model belongs to the electronics automation field.
The utility model is a kind of being inserted in the Microcomputer box, controls microcomputer automatically at the time self-opening power supply of setting and the control card of powered-down.At present, except that the microcomputer of only a few brand itself had the Auto Power On function, most microcomputers did not have this function; Not seeing has similar Auto Power On control card, has brought inconvenience for microcomputer application in some aspects, and just receiving as stock information must be by manually starting shooting on time, otherwise information will be lost.
The purpose of this utility model provides a kind of control card that inserts in the microcomputer, can substitute artificial Auto Power On and shutdown, makes microcomputer obtain better application.
Implementation of the present utility model is: design has time control circuit and actuating unit (as relay) on control card, and the switch connection of actuating unit and the power switch of microcomputer are in parallel; This circuit by battery or additional power source power supply on the card, makes timing circuit energy operate as normal when the computer power closed condition; When timing arrives the on time of setting, then export control signal and make actuating unit connect computer power; And when the microcomputer open state,, and go up battery charge for card then by the computer power power supply, when timing arrived the unused time of setting, actuating unit disconnected computer power and goes up battery or additional power source power supply by card; Data such as the on time in the time control circuit, unused time, current time and week, date by microcomputer by the keyboard setting.
Below in conjunction with accompanying drawing the utility model is described further: entire circuit is made up of battery B, actuating unit relay J, driving triode D2, charging control diode D1 and address decoding circuitry programming device U2:CAL20V8 on time control circuit U1:AT89C2051, the card.The contact line end of relay is in parallel with the computer power K switch and is connected.The CB of microcomputer, DB directly link to each other with single chip computer AT 89C2051, and address wire AB is connected with single-chip microcomputer by the decoding scheme of U2:CAL20V8 programming sheet.When this is stuck in first installation, manually data such as on time, unused time, current time and week, date is set among the RAM of single chip computer AT 89C2051, and picks up counting from the current time by microcomputer keyboard.When microcomputer is in the powered-down state, make the single-chip microcomputer operate as normal carry out timing by battery B power supply, when the on time among the single-chip microcomputer timing arrival RAM, then exporting the control signal high level makes the D2 conducting and drives the relay J adhesive, computer power is connected, and give battery B charging, and make relay be in attracting state to single-chip microcomputer and relay J power supply; And when the unused time among the timing arrival RAM of single-chip microcomputer, then export the control signal low level, D2 is ended extremely, relay J disconnects, close computer power, this moment, single chip computer AT 89C2051 continued the power supply timing by battery B, thereby reached the purpose of automatic switch computer power.
Claims (3)
1, a kind of microcomputer Auto Power On control card, be made of battery or additional power source on time control circuit, actuating unit and the card, it is characterized in that, time control circuit and actuating unit are when microcomputer is in off-mode, go up battery or additional power source power supply by card, make its operate as normal.
2, microcomputer Auto Power On control card according to claim 1 is characterized in that data such as the on time in the time control circuit, unused time, current time, week, date are by the microcomputer setting.
3, microcomputer Auto Power On control card according to claim 1 is characterized in that, when microcomputer is in open state, goes up battery charge can for card.
