Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a sensor for detecting an object or a person as a reflector by receiving a transmitted wave reflected by an object or a person and receiving a reflected wave whose wavelength is changed by the Doppler effect. In particular, the present invention relates to a microwave sensor using a microwave and a microwave sensor application device using the microwave sensor.

2. Description of the Related Art A microwave radiated to a surveillance space and a reflected wave received from an object in the surveillance space are mixed to detect a Doppler signal generated by the movement of the object, and the level of this Doppler signal and a constant threshold value. Compared with, the principle of a microwave sensor is known which detects a moving object based on the time when the Doppler signal level exceeds the threshold / directivity. The principle of the microwave sensor utilizes that the amplitude of the Doppler signal is proportional to the received signal level from the moving object, and the frequency of the Doppler signal is proportional to the moving speed of the moving object. The principle of the microwave sensor will be briefly described. This type of microphone mouth wave sensor sends microwaves or millimeter waves to a moving body, detects the Doppler shift or beat frequency of the reflected wave returning from the moving body, and detects the distance to the moving body. And the speed of the moving body. The detection system of the microwave sensor that has been used conventionally will be outlined. First, at the time of transmission, the voltage controlled oscillator (V
The modulation signal is input to the CO unit), the triangular wave FM modulation is applied to the transmission center frequency, and the modulated millimeter wave band transmission signal passes through the RF amplification unit or the frequency multiplication unit and the antenna unit. Is transmitted from the mobile to the moving body. The reflected wave reflected by the moving body is received by the antenna section and is demultiplexed by the circulator section to the mixer section. Since the same frequency signal (local oscillation signal) as the transmission wave extracted from the directional coupler is input to this mixer section, the reflected wave is mixed with this transmission wave, so that the difference between the reflected wave and the transmission wave is generated. It is converted into an intermediate frequency signal (IF signal) corresponding to the frequency. This IF signal is amplified by the intermediate frequency amplifier of the next stage and taken out from the output terminal. The formula for obtaining the velocity V of the sensing target from the Doppler shift Δf [Hz] observed in the transducer is as follows. V = (Δf / f) · C · (1 / sin θ) (1) where f: frequency of transmitted wave (Hz), C: propagation velocity of transmitted wave (sound velocity or light velocity) θ: of transmitted beam When no modulation is applied in the dip VCO unit, this difference frequency becomes a Doppler shift component due to the movement of the moving body, that is, the measured object. When the triangular wave modulation is applied, the beat frequency output from the mixer changes every half of the modulation cycle. Therefore, the distance R and the speed V of the moving body are the beats detected during the sweep for increasing the frequency. The frequency component is f
When u and fd are the beat frequency components detected during the sweep when lowering the frequency, they can be calculated by the following equation. R = (Tm · C / 4ΔF) {(fu + fd) / 2} (2) V = (c / 2fo) {(fu-fd) / 2} (3) where C is the speed of light and Δ F is the maximum frequency shift, Tm is the period of triangular wave modulation, and fo is the transmission center frequency.

Microwave sensors have been receiving attention because
In recent years. On November 27, 2000, the Ministry of Posts and Telecommunications announced "A Report of the Telecommunications Technology Council on Sensing Sensors that Use the Microwave Band". According to the report, radio wave sensors such as microwave sensors have been conventionally used for speed guns that measure the speed of a ball in a baseball field, etc., and automatic opening and closing of doors.

[0004]

However, although the principle of the microwave sensor is publicly known, the invention of its application is limited to speed guns, automatic opening and closing of doors, etc., and has not been studied so much. There is a problem. Further, although the above-mentioned report of the council mentions prevention measures and application to the safety field, there is a problem in that there is no suggestion as to other uses of the characteristics of the microwave sensor. Therefore, the present invention systematically examines the application of the microwave sensor, examines the application to which its excellent characteristics can be optimally applied, and improves the industrial usability which has never existed in the past. The purpose is to provide a wave sensor.
