Description
Technical field
The utility model belongs to the antitheft field of transmission system, particularly relates to a kind of cable duct burglary-resisting system be arranged in cable duct.
Background technology
In transformer station, be provided with cable duct, cable duct excavates by designing requirement and builds by laying bricks or stones, the sidewall weld load slotted-angle shelving of ditch ground connection on request, and upper cover, with the underdrain of cover plate, is exactly cable duct.Its purposes is exactly the underground designated lane of cabling, and in the transformer station that some are comparatively remote, staff is less, have some lawless persons enter into cable duct steal cut cable.
More existing cables are directly tied up in the cable into antitheft secant, but this cable cost with anti-theft function is higher, and also have many cables not having antitheft secant, and the cost not having the cable of antitheft secant to transform to these is very high; And antitheft secant can first be peeled away the lawless person that this anti-theft cable is familiar with by some, and then being cut off by cable, is that antitheft secant loses antitheft function.
Utility model content
The purpose of this utility model is a kind of cable duct burglary-resisting system be arranged in cable duct overcoming deficiency of the prior art and utility model.
The utility model is achieved in that a kind of cable duct burglary-resisting system, it is characterized in that: comprise piezoelectric transducer, acoustic control lamp, controller, relay, alarm and wireless communication module, wherein the number of piezoelectric sensor is more than or equal to two, all piezoelectric transducers are connected with the input end of controller with acoustic control lamp, wireless communication module is connected with the low-voltage control circuit terminals of relay, and the terminals of the high-pressure work circuit of relay are connected with power circuit with alarm respectively.
Described controller is single-chip microcomputer; Alarm is loudspeaker; Described wireless communication module is GPRS module, and the model of GPRS module is SIM900A.
The inductive head of described piezoelectric transducer is provided with pressing plate, and described pressing plate is a flat board, and dull and stereotyped plate face is perpendicular to the inductive head of piezoelectric transducer.
The light-emitting component of described acoustic control lamp is LED.
Have the following advantages in the utility model:
Electric system front man is in long-term work, this device is created in conjunction with in firsthand experience, during use, each piezoelectric transducer is arranged on the ground of cable duct, the pressing plate that inductive head is arranged increases to be stolen the lawless person cutting cable and to step on the probability of pressure-sensitive sensor, when there being the electric signal transmission of pressure-sensitive sensor to controller, controller will control alarm equipment alarm, be the sending short message by mobile phone of work of transformer substation personnel simultaneously by wireless communication module, inform that staff has robber to cut cable situation and occurs; Stealing while the lawless person cutting cable enters cable duct, acoustic control lamp also plays forewarning function, when there being the sound, acoustic control lamp lights, and acoustic control lamp is while intimidation lawless person, controller will control alarm equipment alarm, be the sending short message by mobile phone of work of transformer substation personnel by wireless communication module simultaneously, inform staff have robber cut cable situation occur, acoustic control lamp select LED be in order to, LED is arranged in wall, is not easy the destruction of suffering lawless person.
This apparatus structure is simple, has multiple alarm mechanism, responds to sensitive, low cost.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
