Description

SYXI-4 model audible acciden signaller
The utility model is a kind of accident signal signalling alarm equipment, belongs to the improvement design that the control of central authorities of existing factories and miness electric substation monitors the accident of using audio alerting unit.
The accident signal telltale of factories and miness electric substation employing at present mainly contains following two types.
One, relay switch with mechanical contact control type adopts the alarm bell sounding alarm, or is equipped with incandescent lamp and makes light signal and show.
Two, have in recent years and adopt the electronic circuit alarm type, with hummer or dynamic loudspeaker sounding alarm or be equipped with different luminescent devices and make light signal and show.
More than two types of alarms all have certain shortcoming using and make, mainly contain following several respects:
1, all need ac power supply, AC power comes from electric substation's distribution system again, in case distribution system breaks down when having a power failure, warning device just can't be worked.
2, electrical source consumption is big, and the general alarm device all can not be made direct supply with dry cell.
3, the warning tone is single, no matter that road controller switching equipment breaks down, all sends identical warning tone, and the staff can't judge that pipeline equipment breaks down.
4, electronic circuit adopts discrete component to assemble more, complex manufacturing, and the debugging amount is big, and functional reliability reduces.
5, do not possess self measuring ability.Behind the long-time utilization and operation, can't detect the reliability of self performance, in case promptly controller switching equipment accident occurs and when in time not reporting to the police, can't distinguish is operator on duty's responsibility, or the fault of machine.
The purpose of this utility model is that design is a kind of easy to use, can overcome the novel alarming device of above two kinds of existing problems of warning device.
The utility model principle of work is summarized as follows:
As shown in drawings, during the utility model operate as normal, AC and DC AC-battery power source circuit is exported a stable operating voltage and is added to button switch " AN " and hand control switch K 1, K 2, K 3, K 4A side, button switch is in normally open at ordinary times, hand control switch K 1K 2, K 3, K 4All place " closure " state, equipment protection contact switch 1DL, 2DL, 3DL, YJ then are in " often opening " state, and each acousto-optic circuit makes this device be in mute silent state on duty because of can not get operating voltage.
When the equipment that is monitored when a certain road broke down, then the corresponding protection contact switch promptly became " closure " state by " often opening " state.At this moment, the operating voltage of being exported by power circuit will be added to corresponding light display circuit, four tones of standard Chinese pronunciation sequence circuit, and on the gated diode, and by the gated diode forward conduction, and then add on simulation four tones of standard Chinese pronunciation circuit and the audio amplifier circuit.Like this, this device will be made corresponding sound, light display alarm timely and accurately.
Accompanying drawing is the utility model circuit diagram.Wherein figure one is the principle of work block scheme, and figure two is an electrical schematic diagram.
In conjunction with the accompanying drawings the utility model is further described.
The utility model is made of following circuit.
1, one four tunnel accident identification circuit is used to monitor four pipeline equipments and provides two-way corresponding identification signal;
2, four tones of standard Chinese pronunciation sequence circuit is used to receive a road above-mentioned identification signal, and exports a control signal corresponding;
3, four tones of standard Chinese pronunciation acoustics circuit receives the control signal of above-mentioned four tones of standard Chinese pronunciation sequence circuit output, thereby audible alarm correspondingly is provided.
4, light signal display circuit receives another above-mentioned road identification signal, thereby alarm indication correspondingly is provided;
5, a power supply automatic switching circuit is used for the conversion of AC power and direct supply, provides power supply to above-mentioned each circuit.
Four tunnel accident identification circuits and four tones of standard Chinese pronunciation sequence circuit are made up of following components and parts: toggle switch K 1, K 2, K 3, K 4, equipment protection contact switch 1DL, 2DL, 3DL, YJ, crystal diode D 7, D 8, D 9, D 10, D 11, relay J 1Current-limiting resistance R 7, R 8R 9, voltage stabilizing diode DW 1, DW 2, DW 3, simulation four tones of standard Chinese pronunciation integrated circuit (IC) 2Form.Wherein:
D 7R 7DW 1R 9DW 3Form first via tone control circuit when it is devoted oneself to work, can make the control end SEL of IC be high level, SEL is empty state, and IC exports first kind of tone;
D 8, R 7, DW 1, J 1, D 11Form No. the second tone control circuit, when it is devoted oneself to work, can make IC 2Control end SEL 1Be low level, SEL 2Be empty state, IC 2Export second kind of tone
D 9, R 7, DW 1Form the Third Road tone control circuit, when it is devoted oneself to work, can make IC 2Control end SEL 1And SEL 2All be empty state, IC 2Export the third tone;
D 10, R 7, DW 1, R 8, DW 2Form the No. four tone control circuit, when it is devoted oneself to work, can make IC 2Control end SEL 2Be high level, SEL 1Be empty state, IC 2Export the 4th kind of tone.
Four tones of standard Chinese pronunciation acoustics circuit is by the extensive CMOS simulated sound of miniwatt integrated circuit (IC) 2(CW9561) resistance R 10, R 11, audio frequency preamplifier BG(3DG6), resistance R 12, R 13, R 14, capacitor C 6C 7, C 8, C 9, C 10C 11Integrated audio power amplifier IC 3(LM386), loudspeaker Y DForm.
