Power supply；The sender unit is for emitting the receivable signal of the sounding instrument, the circuit of the sender unit
Having in the prior art much can be applied in the technology, and Fig. 3 is one of which.
User's resistance in described Fig. 4 is High-Voltage Network user load.
The sender unit periodically, intermittent launch 200KHZ acoustic signals.
It further include signal receiving device, the signal receiving device is used to receive the sounding instrument signal, and described in control
Sender unit movement.
The sounding instrument includes display, signal transmitting and receiving machine, sensor, and the signal receiving device includes 200KHZ
Crystal R-T unit, circulator, crystal filter, amplifier, trigger, signal contrast analyzer, transmitting signalling means, switch electricity
Road, crystal oscillator, tuning oscillator, the 200KHZ crystal R-T unit, circulator, crystal filter, amplifier, touching
Send out device, signal contrast analyzer constitutes and receives circuit, the transmitting signalling means, switching circuit, crystal oscillator, tuning oscillation
Device, circulator, 200KHZ crystal R-T unit constitute transmit circuit, and the 200KHZ crystal R-T unit is for receiving sensing
The signal of device emits signal to sensor.
The course of work of protective device: 200KHZ crystal R-T unit senses ship, transmits signal by circulator,
It is transferred to amplifier under the protection of crystal filter, voltage or power amplification by amplifier transmission signal, signal contrast
Analyzer is determined as the signal of ship sounding instrument sending, and trigger will be ordered according to the comparative analysis result of signal contrast analyzer
It reaches transmitting signalling means and order is executed to switching circuit by transmitting signalling means sending signal, finally by crystal oscillator or tune
