Abstract
The invention provides a cable alarm device. The cable alarm device comprises a signal line, a sending end, multiple receiving ends, a control module, and an alarm sending module. The signal line and a to-be-monitored cable together are disposed inside an insulating sheath. The sending end sends a detection electric signal at regular intervals. The detection electric signals are transmitted to the receiving ends through the signal line. The receiving ends are disposed on the signal line in sequence in the transmission direction of the detection electric signals. The alarm sending module sends fault information to a predetermined person. The control module receives the actual frequency, and binds the actual frequency with a corresponding frequency emission unit together and stores the actual frequency and the corresponding frequency emission unit. If the control module does not receive carrier waves emitted by the frequency emission unit, the control module sends information, serving as fault information, of the frequency emission unit to the alarm sending module. People utilize signal transmission to detect whether a cable malfunctions so as to quickly and accurately complete cable safety detection work.

Control module;
Alarm sending module, it sends failure message to predetermined persons;
Wherein, described transmitting terminal also comprises a frequency reception unit; Described frequency reception unit receives the actual frequency that each described frequency transmitter unit is launched, and described actual frequency is uploaded to described control module;
Described control module, it receives described actual frequency, and by described actual frequency and its for frequency transmitter unit bind and store; When described control module does not receive the carrier wave of a frequency transmitter unit transmitting, then the information of this frequency transmitter unit is sent in described alarm sending module as failure message by described control module.Signal wire and cable to be monitored are together arranged in insulating sheath by this device, utilize the transmission of signal in signal wire to check cable whether complete, when certain cable goes wrong, then the signal transmission of this position also there will be fault, the frequency transmitter unit of the receiving end of this position just can not as transmitting terminal transmission frequency, then judge that the cable at this place may go wrong, and send failure message to staff.
Preferably, in described cable alarm, in described control module, prestore the described preset frequency that each described frequency transmitter unit is launched;
Described preset frequency, described actual frequency and the described frequency transmitter unit binding corresponding with it store by described control module.
Preferably, in described cable alarm, described control module calculates the positional information of each described frequency transmitter unit according to the described preset frequency of each described frequency transmitter unit and described actual frequency; Its computing formula is specially:
(mod2π)
Wherein, d represents the distance value of described frequency transmitter unit and described frequency receiving unit,
represent the phase place of described preset frequency,
represent the phase place of described actual frequency, c represents light velocity of propagation value in an atmosphere; F represents actual frequency values.Utilize the distance value that can calculate each receiving end and transmitting terminal of transmission frequency and receive frequency, determine the positional information of each described receiving end further, the position of cable of breaking down so that staff arrives in the very nick of time.
Preferably, in described cable alarm, when described control module does not receive the carrier wave that a frequency transmitter unit launches, then the positional information of two the described frequency transmitter units closed on this frequency transmitter unit is that failure message is sent in described alarm sending module by described control module.Using the positional information of two contiguous frequency transmitter units as failure message, so that staff carries out maintenance investigation in the interval of these two positions, confirm location of accident as early as possible.
Preferably, in described cable alarm, the frequency values of the described preset frequency of each described frequency transmitter unit is different.Different frequency transmitting terminal launches the carrier wave of different preset frequency, can avoid the mutual interference of frequency transmitting terminal like this, is convenient to again the frequency identifying different frequency transmitting terminal fast.
Preferably, in described cable alarm, failure message is sent to predetermined persons as mobile phone short message, mail or micro-letter information by described alarm sending module.
The present invention arranges warning device on cable to be monitored, one signal wire and cable are arranged in insulation sleeve simultaneously, multiple receiving end is set in signal wire, when signal wire is intact, when signal completes transmission smoothly, think while each receiving end receives electric signal that transmitting terminal sends the carrier wave of a preset frequency, when transmitting terminal receives the carrier wave of the n-th receiving end, illustrate normal to the signal transmission of the n-th receiving end from transmitting terminal, when transmitting terminal does not receive the carrier wave of n+1 receiving end transmission, then illustrate that between the n-th receiving end to the (n+1)th receiving end, signal transmission breaks down, cable within the scope of this may be stolen, then send relevant warning message to staff.
