Abstract
The utility model provides an electric cable antitheft alarm device, which comprises an electric cable, a main station, an auxiliary station, a signal transmitting device and a signal detecting device. The main station and the auxiliary station are arranged at two ends of the electric cable. The signal transmitting device is arranged on the main station, and the signal detecting device is arranged on the auxiliary station. The signal transmitting device transmits power carrier signals to the signal detecting device of the auxiliary station when the electric cable is provided with a power load, and transmits direct-current level signals to the signal detecting device of the auxiliary station when the electric cable is not provided with the power load, and the signal detecting device gives an alarm when not receiving signals in a set time cycle.
Description
Technical field
The utility model relates to Cable Transmission Technology, particularly relates to a kind of cable anti-theft alarm device.
Background technology
The cable anti-theft alarm device is widely used in fields such as city illumination, city low-voltage power supply, industrial and mineral distribution.
From the eighties in last century the PLC technology application development so far, ZAP is widely used at communication field.
In recent years along with the price of non-ferrous raw material is soaring, some lawless persons have been stretched to widely distributed various cables to the evil backstage manipulator, the whole nation almost every day all cable situation about being cut take place, especially damaged by theft serious for power cable, causes very big economic loss to country.
In view of the situation, utilize the cable anti-theft alarm device of ZAP to arise at the historic moment.
The core technology of existing cable burglar alarm is exactly the power carrier communication technology on the market, mode of operation is: code is periodically sent out to slave station by main website, the slave station reception also can illustrate that cable is normal by cognizance code, in case cable is cut off, can not receive just warning of code in the one-period from standing in.
But in the practical application, service cable is not charged constantly.Just can finish data carrier when power carrier needs cable to have electrical load, if when cable does not have electrical load, power carrier does not just possess condition of work, and then the cable anti-theft alarm device does not just have the effect of burglar alarm yet.The cable of city street lamp for example, do not turn on light daytime does not just have electricity, have only evening during bright lamp cable just charged, anti-theft alarming equipment just works.
The utility model content
The cable anti-theft alarm system that exists at prior art does not have defective and the deficiency that electricity promptly lost efficacy, the utility model provides a kind of dual signal enhancement mode cable burglar alarm, so-called dual signal, the mode that adopts dual signal source to detect is exactly finished input, guarantees that cable all is in monitored state electricity being arranged or do not have under the situation of electricity.
The technical solution of the utility model is as follows:
The cable anti-theft alarm device, comprise it is characterized in that the main website and the slave station at cable and cable two ends: described cable anti-theft alarm device comprises sender unit that is arranged at main website and the signal supervisory instrument that is arranged at slave station.Described sender unit sends the signal supervisory instrument of power carrier signal to slave station in that cable is charged when promptly having electrical load; In that cable is not charged when promptly not having electrical load, send the signal supervisory instrument of dc level signal to slave station; Described signal supervisory instrument does not receive signal and reports to the police at once in the time cycle of setting.
Also comprise in the described main website in order to switch the signal shifter of transmission and reception carrier signal or dc level signal.
Also comprise the wireless communication apparatus that is used to send and receive alerting signal in the described slave station.
Technique effect of the present utility model is:
By between the main website and slave station at cable two ends; at cable in the uncharged time; send and receive dc level signal; even reach under the uncharged situation of cable; still cable is carried out the burglar alarm protection; overcome in the existing power transport field, cable anti-theft alarm under unsupported situation, the defective of the online protection of no efficient real time.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, main station controller 1 has two sender units respectively: power carrier signal dispensing device 2 and dc level signal dispensing device 3 also comprise signal shifter 4; Comprise two signal receiving devices from station control 6: power carrier signal receiving trap 7 and dc level signal receiving trap 8, and signal shifter 5 also comprise wireless signal communication device 9.
When having electrical load in the cable, the power carrier signal dispensing device 2 of main website sends power carrier signal to slave station, and power carrier signal receiving trap 7 received signals do not receive this signal in the slave station in setting cycle, it is stolen promptly to can be considered cable, reports to the police by warning device; Warning device can adopt forms such as light or audible alarm, in the present embodiment, and preferred wireless signal remote alarms.
When not having electrical load in the cable, the cable anti-theft alarm device gets final product by the carrier signal mode switch main website sender unit and slave station signal receiving device by signal shifter for the dc level signal pattern.
The above is a preferred implementation of the present utility model only, but is noted that for any improvement and modification based on the present utility model spirit and essence, all should be covered by protection domain of the present utility model.
Claims (3)
1. cable anti-theft alarm device, the main website and the slave station that comprise cable and cable two ends, it is characterized in that: described cable anti-theft alarm device comprises sender unit that is arranged at main website and the signal supervisory instrument that is arranged at slave station, described sender unit is launched the signal supervisory instrument that power carrier signal is given slave station when cable has electrical load, the emission dc level signal is given the signal supervisory instrument of slave station when cable does not have electrical load, and described signal supervisory instrument does not receive signal and reports to the police at once in the time cycle of setting.
2. cable anti-theft alarm device as claimed in claim 1 is characterized in that: also comprise in described main website and the slave station in order to switch the signal shifter of transmission and reception carrier signal and dc level signal.
