Therefore need to develop a kind of new warning system, can based on power line carrier communication detection technique, and adopt gsm wireless to report to the police, the method installs carrier communication equipment at cable two ends respectively, judge that whether cable is intact by carrier communication success or failure, reported to the police by gsm wireless immediately when cable break being detected.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency for above-mentioned existence, there is provided a kind of detection method reliable, report to the police in time, not only be conducive to improving for electrical stability, and have certain deterrent effect to lawless person, the electric system low-voltage cable disconnection fault monitoring system of economic loss can be reduced to the full extent.
The utility model solves the technical scheme that its technical matters adopts:
Electric system low-voltage cable disconnection fault monitoring system, adopt dual power supply, it is characterized in that: include the monitoring main website being arranged on cable one end, along the line as required at different interval installation detector at cable, adopt trunking traffic working method, main website sends request signal once to each detector, and detector is write in reply to main website after receiving inquiry; Described monitoring main website includes a main control chip, and main control chip is connected with dual power supply, voice module, acceleration sensor, gsm module, signal transmission and signal receiving circuit; Described gsm module, voice and note two kinds of modes can send alerting signal, the signal that staff sends by receiving gsm module, short information of cell phone remote arranges monitoring system parameter.
In such scheme, described dual power supply comprises mutual inductor power taking and storage battery power supply two schemes, forms primary power and standby power supply.
In such scheme, described main control chip selects the carrier chip of 51 kernels as master controller, and hardware includes output power amplifying circuit, carrier signal input and output coupling port, carrier signal receive filter circuit, carrier signal receives selective frequency amplifier circuit, power circuit, GSM alarm module circuitry, RS232 communication interface circuit, software mainly completes main control chip initialize routine, carrier signal transmission program, carrier signal reception program and gsm wireless alert program.
In such scheme, described main control chip reserves an I/O mouth, can be used for controlling outer panalarm or switchgear, as loudspeaker, relay.
Principle of the present utility model is broken by power line carrier communication detection streamer, namely monitoring main website is installed in cable one end, in cable appropriate interval along the line, detector is installed, whole system adopts trunking traffic and training in rotation working method, main website sends request signal once to each detector, detector is write in reply to main website after receiving inquiry, monitoring main website judges cable status by whether receiving corresponding letter in reply, can receive and then illustrate that cable is intact, otherwise judgement cable break, now send AT instruction by RS232 serial ports to gsm module, control gsm module transmission alarming short message to cease to staff.
The beneficial effects of the utility model are:
The utility model detection method is reliable, reports to the police in time, is not only conducive to improving for electrical stability, and has certain deterrent effect to lawless person, can reduce economic loss to the full extent.

Embodiment
Below in conjunction with embodiment, the utility model is further described:
Electric system low-voltage cable disconnection fault monitoring system as shown in Figures 1 to 7, adopt dual power supply, include the monitoring main website being arranged on cable one end, along the line as required at different interval installation detector at cable, adopt trunking traffic working method, main website sends request signal once to each detector, and detector is write in reply to main website after receiving inquiry; Described monitoring main website includes a main control chip, and main control chip is connected with dual power supply, voice module, acceleration sensor, gsm module, signal transmission and signal receiving circuit; Described gsm module, voice and note two kinds of modes can send alerting signal, the signal that staff sends by receiving gsm module, short information of cell phone remote arranges monitoring system parameter.
In the present embodiment, described dual power supply comprises mutual inductor power taking and storage battery power supply two schemes, forms primary power and standby power supply.
In the present embodiment, described main control chip selects the carrier chip of 51 kernels as master controller, and hardware includes output power amplifying circuit, carrier signal input and output coupling port, carrier signal receive filter circuit, carrier signal receives selective frequency amplifier circuit, power circuit, GSM alarm module circuitry, RS232 communication interface circuit, software mainly completes main control chip initialize routine, carrier signal transmission program, carrier signal reception program and gsm wireless alert program.
In the present embodiment, described main control chip reserves an I/O mouth, can be used for controlling outer panalarm or switchgear, as loudspeaker, relay.
The utility model embodiment adopts 220V Power supply, and be that 12V enters monitoring system by internal electric source module converts, 12V is converted to 5V by 7805 Voltage stabilizing modules and powers by partial circuit, as main control chip and GSM alarm module.
First system initialization after monitoring system starts, then carrier communication data are generated by master routine, and be stored in carrier wave output register, when data in this register write carrier wave transmitter register by turn, band spectrum modulation is completed by main control chip inside, the signal modulated exports from main control chip P1.7 mouth, output signal is the square-wave signal of 120kHz, this signal is through power amplification circuit, input and output coupled circuit enters cable transmission, arrive the monitoring detector of the other end, coupling port through detector enters detector, through elementary filtering circuit, selective frequency amplifier circuit, pottery filtering, enter main control chip afterwards, decoded by main control chip, write in reply to main website after determining the information that monitoring main website sends, if main website successfully receives detector and writes in reply, then illustrate that monitored cable is intact, do not start warning, if the continuous several times inquiry of monitoring main website does not all receive the letter in reply of detector, then judge that cable is destroyed, start gsm wireless to report to the police.
This electric system low-voltage cable disconnection fault detection system, self is antitheft is realized by external acceleration sensor, this monitoring system is arranged in power distribution cabinet usually, now acceleration sensor can be installed on distribution cabinet door inside, when attempting when there being people to open power distribution cabinet, acceleration sensor exports and sends change, and main control chip detects that this change just starts warning later.
This electric system low-voltage cable disconnection fault detection system has standby power supply, common work can be continued when grid power blackout, standby power supply is accumulator and solar panels, accumulator is in full state under normal circumstances, power supply state is entered during grid power blackout, now solar panels charge a battery, and accumulator is powered to monitoring system.
More than illustrate and be only Application Example of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalence change that the utility model claim is done, still belong to protection domain of the present utility model.
