Also can be in company with deformation, its resistance also will change accordingly.Utilize this resistance strain effect of strain resistor, can be by elasticity
Displacement device pressure experienced signal is converted to signal of telecommunication output.
As depicted in figs. 1 and 2, in this utility model embodiment, pressure transducer 33 is connected to, by wire 34, dress of reporting to the police
Put, and the path of wire 34 is through waterstop 5.Utilize waterstop as 5 connect pressure transducers 33 wire 34 paths, permissible
Save the operation separately setting path for wire 34, it is simple to the enforcement of the board-like retractor device of comb.
The board-like retractor device of comb that this utility model embodiment provides, by across seam fishback unit 1, fixed fingers plate list
Unit 2 and elastic composition such as displacement device 3 parts such as grade.Elastic displacement device 3 therein includes spaced steel plate 31 and high-damping
Rubber 32, and between steel plate 31 and high-damping rubber 32, it is provided with one or more pressure transducer 33, this pressure sensing
Device 33 can be used for being connected to alarm device.When elastic displacement device 3 is rolled, by vehicle, the pressure caused, it is arranged on steel plate 31
And the pressure transducer 33 between high-damping rubber 32 just can sense elastic displacement device pressure experienced accurately, and will
The size transmission of this pressure is to alarm device, it is achieved thereby that security alarm when elastic displacement device 3 stress is excessive, to avoid
There is permanent deformation in elastic displacement device 3, improves the safety of the board-like retractor device of comb.

Between circuit 51 and pressure transducer 33. the analogue signal that pressure transducer 33 is sent by amplifying circuit 54 is amplified, and will
Analog signal output after amplification is to comparison circuit 51.
Amplifying circuit is to increase the electronic circuit of electrical signal amplitude or power, and the device that application amplifying circuit realizes amplifying can
It is referred to as amplifier.The core of amplifying circuit is electronic active device, such as electron tube, transistor etc..In order to realize amplifying, it is necessary to give
Amplifier provides energy, and the conventional energy is DC source, but some amplifiers also utilize high frequency electric source as pumping source.
The essence of amplification is that the energy of power supply is shifted as output signal, and the effect of input signal is to control this turn
Move, enable the change of the output signal of amplifying circuit to repeat or the change of reflected input signal.In contemporary electronic systems, telecommunications
Number generation, send, receive, convert and process, nearly all based on amplifying circuit.
Modern use the widest based on transistor (bipolar transistor or field-effect transistor) amplifying circuit
Integrated amplifier.And high-power amplification and high frequency, the low noise amplification of microwave, generally use discrete transistor amplifier.High
The high-power amplification of frequency and microwave is mainly by the vacuum tube of specific type, such as pliotron or tetrode, magnetron, velocity modulation
Pipe, travelling-wave tube and crossed-field amplifier etc..
In the present embodiment, alarm 53 can include alarm lamp and emergency alarm bell, and alarm lamp and emergency alarm bell can be arranged
The positions such as the security department at bridge.When elastic displacement device pressure experienced is excessive, alarm lamp will light warning light, with
Times alarm bell also can send alarm sound, to remind the maintenance staff of bridge.
Wherein, alarm lamp is preferably LED alarm lamp.Light emitting diode (Light Emitting Diode is called for short LED) is
The semiconductor device of a kind of solid-state, it directly can be converted into luminous energy electric energy.LED has light efficiency height, little power consumption, life-span
The advantages such as long, easy to control, non-maintaining, safety and environmental protection, are a new generation's solid cold light sources.Because LED caloric value is the highest, electric energy
Amount is converted into luminous energy as much as possible；And common lamp is converted into heat energy because of the many electric energy of big of caloric value.Therefore, it is compared
Under, LED lamp can significant saves energy.
Additionally, in other embodiments, report to the police and the one in alarm lamp and emergency alarm bell wherein can also be only set.
In the security alerting system that this utility model embodiment provides, alarm device can be arranged on traffic administration room or guarantor
In Work Safety Office.When elastic displacement device is rolled, by vehicle, the pressure caused, pressure transducer just can sense bullet accurately
Property displacement device pressure experienced, and the size of this pressure is transmitted to alarm device.
When elastic displacement device pressure experienced is excessive, and alarm occurs to report to the police, staff just can find in time
This alarm signal, in order to elastic displacement device and the board-like retractor device of comb are safeguarded.
Therefore, the security alerting system that this utility model embodiment improves, it is achieved that when elastic displacement device stress is excessive
Timely security alarm, to avoid elastic displacement device generation permanent deformation, improve the safety of the board-like retractor device of comb
