Description
[technical field]
The utility model relates to electronic alarm device, particularly a kind of alarm.
[background technology]
Recent years, China's power supply shortage becomes social hot issue gradually.In the peak period in many areas, there is again the phenomenon of power cuts to limit consumption in electric power supply, at present many occasions higher to electrical power demand, if cause the problem of heavy losses as the aerating machine etc. in hatchery, fish pond occurs that power-off is powered not in time.Even and if a lot of equipment is in monitoring state still at substantial electric energy and duration of work power is large, big energy-consuming in the market, therefore research manufactures energy-efficient equipment and seems particularly important.
[utility model content]
The purpose of this utility model is to provide a kind of energy-conservation alarm, with after avoiding power-off not in time power supply cause heavy economic losses, and the current common power-off alarm moment is in detected state thus the problem causing waste of energy serious.
To achieve these goals, the utility model adopts following technical scheme:
A kind of energy-conservation alarm, comprises transformation power-supply unit, depletion mode field effect transistor, microcontroller power supply, single-chip microcomputer, triode and warning device; The high-pressure side of transformation power-supply unit connects electrical network to be monitored, transformation power-supply unit low pressure end connect depletion mode field effect transistor, for depletion type insulated gate field effect transistor provides reverse voltage; Microcontroller power supply connects single-chip microcomputer by depletion type insulated gate field effect transistor, and the output terminal of single-chip microcomputer connects warning device by triode.
Further, described transformation power-supply unit is charger for mobile phone.
Further, described warning device is voice guard.
Further, described warning device is light crossing-signal.
Further, described warning device is audible-visual annunciator.
Further, described warning device is mobile phone, and triode connects the function button of mobile phone, and single-chip microcomputer connects the mainboard of mobile phone; The conducting of triode is for controlling mobile phone power-on; Single-chip microcomputer is transferred the number prestored carry out call alerts for being controlled mobile phone.
Further, the model of described single-chip microcomputer is STC89C52.
Further, during the non-off-position of electrical network to be monitored, voltage is dropped to 5 volts by the transformation power-supply unit be connected with high-voltage fence, and 5 volts of voltages provide reverse voltage for depletion type insulated gate field effect transistor, and depletion mode field effect transistor reverse voltage is ended; The depletion mode transistor being in pinch off state can not make microcontroller power supply power to single-chip microcomputer.
Further, during grid cut-off state to be monitored, the transformation power-supply unit that high-voltage fence is connected is in off-position; Depletion mode field effect transistor loses pinch-off voltage and is in conducting state, and microcontroller power supply bio-occlusion single-chip microcomputer is powered; Single-chip microcomputer is used for controlling warning device by the conducting of triode and reports to the police.
Relative to prior art, the utility model has following beneficial effect: the utility model is when the non-power-off of electrical network, and alarm is in off-mode and does not consume electric energy, once there is powering-off state, Auto Power On is reported to the police by alarm, reports to the police after reaching set point number and shuts down, be in zero-power state.The Key Electron Device used in alarm is depletion type insulated gate field effect transistor, make use of the characteristic adding reverse voltage pinch off of transistor in design, thus achieves the energy-conservation object of standby zero-power-consumption at ordinary times.At alarm work state power less than 1 watt, and current alarm work be power all more than 1 watt, thus reach and realize saving the object of electric energy.The energy-conservation power-off alarm of the utility model not only saves electric energy, can also carry out intelligent monitoring, and properties of product are stablized, and the replacement cycle is long.
[accompanying drawing explanation]
Fig. 1 is circuit theory diagrams of the present utility model.
Wherein, charger for mobile phone 1, depletion mode field effect transistor 2, microcontroller power supply 3, single-chip microcomputer 4, triode 5 and mobile phone key 6 is comprised.
[embodiment]
Refer to shown in Fig. 1, a kind of energy-conservation alarm of the utility model, comprises charger for mobile phone 1, depletion mode field effect transistor 2, microcontroller power supply 3, single-chip microcomputer 4, triode 5 and warning device 6.
The high-pressure side of charger for mobile phone 1 connects high-voltage fence, and the low pressure end of charger for mobile phone 1 connects depletion mode field effect transistor 2, for depletion type insulated gate field effect transistor 2 provides reverse voltage; Microcontroller power supply 3 connects single-chip microcomputer 4 by depletion type insulated gate field effect transistor 2, and the output terminal of single-chip microcomputer 4 connects warning device 6 by triode 5.
During the non-off-position of high-voltage fence, high pressure is dropped to 5 volts by the charger for mobile phone 1 be connected with high-voltage fence, 5 volts of voltage provides reverse voltage (now no current and zero-power in depletion mode field effect transistor 2) for depletion type insulated gate field effect transistor 2, thus makes depletion mode field effect transistor 2 reverse voltage end (depletion mode field effect transistor 2 pinch-off voltage Ugs (off) <5V).The depletion mode transistor 2 being in pinch off state can not make microcontroller power supply 3 power to STC89C52 single-chip microcomputer 4, thus the switch that single-chip microcomputer 4 can not control triode 5 has carried out the control to warning device 6, and warning device 6 can not be reported to the police.
During high-voltage fence off-position, charger for mobile phone 1 power cut-off, now, depletion mode field effect transistor 2 loses pinch-off voltage and conducting, microcontroller power supply 3 bio-occlusion STC89C52 single-chip microcomputer 4 is powered, single-chip microcomputer, by reading the program in single-chip microcomputer, controls the folding of triode 5 by the change of low and high level, thus controls warning device 6 and be energized.Warning device 6 can be audible-visual annunciator or mobile phone; When warning device 6 is audible-visual annunciator, the conducting of triode 5 makes audible-visual annunciator send sound and light alarm signal, the power-off of warning high-voltage fence.When warning device 6 is mobile phone, triode 5 connects the function button of mobile phone, STC89C52 single-chip microcomputer 4 connects the mainboard of mobile phone, the conducting of triode 5 makes mobile phone power-on, STC89C52 single-chip microcomputer 4 controls the number that storage transferred by mobile phone, repeated call (can set the number of calls), by orders such as automatic shutdowns after calling.
Energy-conservation power-off alarm is easy to use, only needs power supply (common charger) to be inserted in the high-voltage fence be connected with common insert row, then by the switch opens on intelligent power saving power-off alarm.
