Abstract
The utility model relates to a voice prompting device for electric power control switches of transformer stations. The inner structure of the utility model comprises an infrared transmitting device, an infrared receiving device and a high-performance voice circuit. The utility model is characterized in that a state sensor is formed by using the infrared transmitting device and the infrared receiving device when human's hands approach to a switch. Then, the high-performance voice circuit is triggered to work so as to send out a voice prompt through a photocoupler. The prompting device is adsorbed below a monitored switch by using the magnetic properties. The utility model can continuously work more than 100 hours.
Description
The utility model relates to a kind of voice reminder that is used for the converting station electric power gauge tap, can prevent operating personnel's maloperation.
The power switch control of transformer station is being controlled the power supply of large areas, and operating switch can cause serious consequence mistakenly.At present, in electric system in order to prevent the maloperation power switch control, the general mode that adopts mechanical latching, such as lock core being fabricated in the rotating shaft of gauge tap, must open the lock with the key, also useful plastics inserted sheet carries out, and red green board turning spacing, that usefulness has the position password carries out anti-misoperation or the like, and said method all has certain limitation, can not remind operating personnel intuitively, prevent maloperation.
The purpose of this utility model provides a kind of voice reminder of power switch control, when it can be close to monitored power switch control certain distance at personnel's hand, sends voice reminder automatically, prevents personnel's maloperation, and easy to install.
The purpose of this utility model is achieved in that a kind of speech prompting device that is used for the converting station electric power gauge tap, comprise housing, sound circuit and sound-producing device, infrared and receiving trap and signal processing circuit, described infrared receiver is connected with sound circuit by signal processing circuit.
In the technique scheme, form the sensor of hand by infrared transmitting device and infrared receiver near gauge tap, when hand is close to the gauge tap certain distance, sensor output action signal, trigger sound circuit work by photoelectrical coupler, send the voice reminder signal.
In the technique scheme, described infrared and receiving trap comprise infrared emission tube and infrared receiver tube, described infrared emission tube, receiving tube are installed on reminiscences shell top, the angle of installing is outward-dipping 45 degree, 1.5 centimetres of spacings, described signal processing circuit can be photoelectrical coupler.
Further technical scheme, described sound circuit is for wiping the sound circuit of record, power down maintenance repeatedly, and a side of reminiscences is provided with the record button of touch-switch control.
Further technical scheme, the back of described housing is provided with magnet, and described magnet can be the strong magnets of four garden sheet shapes.
Owing to adopted technique scheme, the utlity model has following advantage and effect: 1, the utility model has adopted infrared sensing device, can staff near the time send alerting signal automatically, prevent personnel's maloperation.2, the high-performance sound circuit can be recorded at any time, can wipe, and permanent memory, power down can not lost voice messaging, at any time the warning voice that typing is new, thereby can distinguish the strong magnets that is provided with four garden sheet shapes on different switches 3, the shell easily, utilize the mode of directional magnetic field to produce strong magnetic
, can firmly be adsorbed on the control flow, conveniently install and use.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the installation site synoptic diagram of power switch control voice reminder
Fig. 2 is the circuit diagram of power switch control voice reminder
Among the figure: 1, people's hand; 2, monitored and gauge tap 3 that can voice reminder, infrared 4, infrared receiving terminal 5, record button 6, power switch 7, loudspeaker vocal hole 8, power switch control voice reminder body 9, TX05D relay indicating light
Embodiment one: referring to attached illustrated in figures 1 and 2, a kind of speech prompting device that is used for the converting station electric power gauge tap, comprise housing, sound circuit and sound-producing device, infrared and receiving trap and signal processing circuit, described infrared receiver is connected with sound circuit by signal processing circuit.Photoelectric sensor adopts the little power consumption sensor of TX05D, the mode signal output of sensor adopts photoelectrical coupler output, actuating signal indication light-emitting diodes tube loop with the input end of photoelectrical coupler is connected and inserted TX05D can trigger photoelectrical coupler work when TX05D moves like this.Trigger sound circuit work during photoelectrical coupler work again.Sound circuit adopts 20 seconds recording modules of American I SD1420 series, the recording module triggering mode is set to the trigger action mode by wire jumper, working method stops after being set to play voice automatically, in the time of so just realizing that photoelectrical coupler work triggers sound circuit, automatically voice are once reminded in broadcast continuously, stop then.The relay indicating light of TX05D was common 3 millimeters light emitting diodes originally, was replaced with 5 millimeters superhigh brightness LEDs here, can improve brightness, reduced power consumption.The power supply of reminiscences adopt 450 milliamperes at No. 7, four joints/time the nickel-hydrogen chargeable cell power supply, power switch and record button are connected to the left and right sides of reminiscences shell by lead-in wire.
Owing to adopt such scheme, the one-piece construction of reminiscences is less than 35 * 80 * 55 millimeters, the voice that can typing in the reminiscences need warn, as: " testing crew is drag switch by mistake! " can carry out voice reminder when making 5 centimetres of monitored power switch control control handles to personnel, effectively prevent personnel because negligence causes a serious accident.And power consumption economizes very much when in the monitoring state, and quiescent current is less than 3 milliamperes, can continuous working more than 100 hours.
