Summary of the invention
This utility model provides a kind of opening/closing control device just for weak point existing in above-mentioned prior art.
The purpose of this utility model can be realized by following technique measures:
Opening/closing control device of the present utility model includes double-pole two-position relay, self-resetting switch machine button, the power supply of low-voltage DC, optical coupling module, singlechip control panel, the RS-232 interface of computer or USB interface, first group of common port of wherein said double-pole two-position relay connects 220V live wire, first group of normally opened end is connected with the live wire input of first group of normally opened end of self-resetting switch machine button and the power supply of low-voltage DC and controlled electrical equipment live wire end respectively, second group of common port of double-pole two-position relay connects first group of normal-closed end of self-resetting switch machine button, second group of normally opened end of double-pole two-position relay connects the live wire input of optical coupling module, coil windings first end of double-pole two-position relay connects the+12V outfan of the power supply of low-voltage DC, coil windings the second termination circuit switching plate amount output of double-pole two-position relay, by Single-chip Controlling, 220V live wire end is connected after second group of normally opened end of self-resetting switch machine button and normal-closed end short circuit, the display lamp negative pole of self-resetting switch machine button connects the+12V output negative pole of the power supply of low-voltage DC, and+12V the end of self-resetting switch machine button connects the+12V of the power supply of low-voltage DC,The N end of the power supply of low-voltage DC connects the zero line of 220V, and FG end is unsettled or connects the ground wire of 220V, and+12V the outfan of the power supply of low-voltage DC connects the OUT terminal of optical coupling module; The signal of optical coupling module output connects singlechip control panel, and the USB interface of singlechip control panel connects RS-232 interface or the USB interface of computer, and the RS-232 interface of singlechip control panel connects RS-232 interface or the USB interface of computer.
The button of self-resetting switch machine described in this utility model is hilted broadsword dibit or double-pole dibit self-resetting switch machine button; Described optical coupling module is light-coupled isolation module or transformer isolation module; Singlechip control panel is the single-chip microcomputer of single-chip microcomputer or the ARM kernel using 8051 kernels.
Operation principle of the present utility model is as follows:
When switching on and shutting down button is pressed, whole system powers on, simultaneously singlechip control panel also electric, control relay adhesive, due to the relation that the normally opened contact of the normally opened contact of switching on and shutting down button and relay is in parallel, even if trip switch machine button after powering on, whole system still electric, it is achieved thereby that start process.
During shutdown, when switching on and shutting down button is pressed, another group normally opened contact and series relationship of switching on and shutting down button normally-closed contact due to relay, optical coupling module must not be electric, the output of optical coupling module can from before high level become low level, this level is detected by singlechip control panel, it is consecutively pressed three seconds and may be considered off signal, now singlechip control panel starts to detect the voltage of the RS-232 interface of computer or USB interface, when detecting that voltage is reduced to a certain numerical value, namely it is believed that computer has logged out operating system and enters off-mode, achieve detection computer shutdown, relay power-off can be controlled, singlechip control panel and Switching Power Supply are also by Control, so when there is no any current drain after relay power-off, achieve closedown zero power consumption.
When computer software closes closed system, first passed through RS-232 interface or USB interface by computer software and send a shutdown command to singlechip control panel, then singlechip control panel begins to detection computer shutdown, when cut-off condition meets, just disconnects cut-off system.
When network remote closes closed system, order is sent by network to local computer by remote control terminal, local computer sends shutdown command again through RS-232 interface or USB interface to singlechip control panel after receiving order, then singlechip control panel begins to detection computer shutdown, when cut-off condition meets, just disconnect cut-off system.
The beneficial effects of the utility model are as follows:
One, forceful electric power, light current, computer software three-in-one integrated are realized.
Two, closed system can be closed by computer software or network remote.
Three, zero-power (there are about 1 ~ 2 watt of stand-by power consumption after the shutdown of the household electrical appliance such as air-conditioning, television set, after the shutdown of this circuit, power consumption is really zero watt) after closing closed system.
Four, hardware circuit can pass through RS-232 interface or the shutdown of USB interface detection computer when not affecting data communication, communicates, detects two-in-one, is not take up other hardware interfaces of computer.
Five, when the operating system of computer exits and enters off-mode afterwards, just full power-off enters zero-power state; protect hard disc of computer; data are made not wrecked by the impact of unexpected power-off, in Industry Control and the occasion that data demand is higher is particularly important.
