It is verified, is then forwarded to hand-held set and shows, this partial circuit is for detecting locator message.
The frequency of use of locator is 1664KHz, and according to resonance principle, the tranmitting frequency of locator is closer from 1664KHz
Intensity is stronger, otherwise weaker.Around this principle, locator index can be judged by the intensity of detection locator transmitting
Departure degree.As described above, having made a rectification circuit after receiving circuit, the AC signal received is become into direct current
Pressure, then numerical value is sent to hand-held set after being acquired by main control unit.Locator transmitting can be reacted by force by thus having obtained one
The numerical value of degree compares the locator emissive porwer numerical value of this numerical value and standard, so that it may obtain the index of locator
Departure degree.
The present embodiment realized on hardware circuit detection locator index function, while can real-time display, quickly examine
The departure degree for surveying the index of locator solves the problems, such as that the detection of puzzlement locator, maintenance are inconvenient all the time.
As shown in Figure 5, abscissa is frequency, and unit Hz, ordinate is intensity, unit V.The design frequency of locator
For 1664 KHz, so the emissive porwer of locator is stronger when the frequency of locator is closer to 1664KHz, the electricity obtained after conversion
Pressure value is higher.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
