[embodiment]
As shown in Figure 1, a kind of touch type audible and visible alarm fence, comprise chassis 1 and be fixed on The One On The Chassis column 2, above-mentioned chassis 1 can adopt cast iron materials to make, equally also can adopt concrete material to make, have suitable weight as long as guarantee it, satisfy standing in of guaranteeing in using that above-mentioned fence can be stable on.Also can be provided with on the above-mentioned chassis 1 and decorate chassis cover 3, this chassis cover 3 adopts the stainless steel material impact briquetting to make, and can also use plastics in addition, and modes such as the outer painting of common steel are made, and to guarantee it profile attractive in appearance are arranged, and coat above-mentioned chassis 1.In the acoustic-optic alarm 4, battery 5, power switch 6 and the control circuit part that are arranged on the chassis 1 on the column 2, column is the tubulose 2 of hollow, and above-mentioned Webbing take-up device 7, battery 5, power switch 6 and control circuit part all are arranged in the cavity in the above-mentioned column 2.Battery 5 is rechargeable lithium battary or Ni-MH battery.Acoustic-optic alarm 4 is arranged on the top of column 2, and light-emitting lamp wherein is LED light emitting diode and the loudspeaker that are used to send alarm sound.Described warning tape 8 is wrapped on the Webbing take-up device 7, this Webbing take-up device 7 is fixed in the cavity at column 2 middle parts, and by the 10 winding warning tapes 8 of the hinge axis in the middle part of it, this warning tape 8 is by stretching out in the square through hole on column 2 sidewalls, one end of above-mentioned warning tape 8 is provided with hook 11, this warning tape 8 is made by engineering plastics, spring steel plate and nylon knitting belt, and adopts the method for that fluorescence warning mark to carry out surface treatment.One end of hinge axis is provided with the press-type induction installation of pulse producer 15 and control circuit formation, and this pulse producer 15 can be experienced the displacement of warning tape under the situation of power connection, and produces corresponding signal, is input in the above-mentioned control circuit.Above-mentioned column 2 inwalls are provided with support 12 and are used for installing above-mentioned hinge axis, concrete fixed form comprise welding, bonding, screw is affixed etc., and multiple mode realizes.Also be provided with hanging hook 13 on the above-mentioned column 2, the position of above-mentioned hanging hook 13 is relative with the rectangular through holes position of warning tape 8, just in time is positioned at the relative position, both sides of column 2.Described control circuit comprises battery low pressure indicating circuit and electronic switching circuit.Also be provided with charging socket 14, power supply low pressure pilot lamp 9 and power switch 6 on the column, these parts operated by rotary motion can prevent the short circuit of intaking on the top of column 2 in sleety weather, improve the security of using.
As shown in Figure 2, this circuit separated into two parts: a part is a battery low pressure indicating circuit; Another part is an electronic switching circuit.
The designing requirement of battery low pressure indicating circuit is when cell voltage drops to 10.5V, the luminous prompting of LED lamp.Circuit design is that the input end of receiving comparer respectively by the reference voltage of voltage stabilizing diode gained with cell voltage compares with the voltage of cell output voltage by gained behind the electric resistance partial pressure.When voltage during greater than 10.5V, voltage after partial is higher than reference voltage, the comparer output low level, and LED light does not work.When voltage dropped to 10.5V, because this moment, voltage after partial was lower than reference voltage, comparer output high level was lighted pilot lamp, and the staff is to charge in batteries in caution.
The electronic switching circuit designing requirement is when the people touches the fence net, and switch closure is connected sound and light alarm device and reported to the police.Because touching is a short time action just, so in order to reach the warning required time, used a RC circuit in circuit.Circuit is when touching the fence net by the people, drive motor and rotate, and motor rotates the generation electromotive force, on two extension lines of motor voltage drop is just arranged like this.Two pins is received respectively on 5,6 pin of comparer, because voltage drop is arranged, then at 7 pin output high level.7 pin are received the positive pole of electric capacity and 3 pin of comparer.Connecing electric capacity is when 7 pin are high level, and electric capacity is charged.Connecing 3 pin then is to compare by the reference voltage that voltage stabilizing diode provides with voltage, when 7 pin are high level, the voltage of 3 pin is higher than the reference voltage of 2 pin, 1 pin output high level, so that the single-transistor conducting, this is that an end of relay just has electric current to flow through, produce magnetic strength, the adhesive switch, the warning circuit conducting makes sound and light alarm device work.When motor was failure to actuate, 7 pin were output as low level, and circuit should not worked, but because when 7 pin are output as high level, with to the electric capacity charging, so the level of 3 pin input also than reference voltage height, 1 pin is still exported high level.When voltage is lower than reference voltage after having only electric capacity by conductive discharge, 1 pin output low level, alarm stops to report to the police.
Pull out during use after the fence band hangs up properly, turn on the power switch, warning system is in holding state.As press the fence band, and then the fence band produces displacement and drives pulse producer along pull-out direction and produces pulse current, and pulse current trigger switch circuit is connected the audible-visual annunciator power supply, the beginning sound and light alarm.Continuous alarm stops after 3 seconds automatically.
