Description

TECHNICAL FIELD [0001] The present invention relates to a portable test apparatus for a motion detection sensor,

The present invention relates to a portable test apparatus for a motion detection sensor, and more particularly, to a portable test apparatus for a motion detection sensor capable of testing the detection performance of a motion detection sensor by distance through wireless communication, The present invention relates to a portable test apparatus for a motion detection sensor, which can easily perform a test operation and accurately confirm detection information of a motion detection sensor by distance.

The motion sensor detects movement or distance of the body when there is movement of the body in front of the sensor, and there are RF sensor, infrared sensor and ultrasonic sensor. In particular, an RF sensor transmits a radio wave of a specific frequency, for example, a microwave, and then applies a Doppler effect of detecting a reflected wave of the signal to detect a frequency change along the distance to output a detection signal.

Because the RF sensor uses radio frequency, it can transmit and receive through the wall, and it can send radio waves to a large area. Here, the Doppler effect refers to a phenomenon in which a wave is returned when it is struck by a stationary object, but the frequency is different when a moving object is struck and reflected.

Microwave band RF sensors are newly introduced with reliable operation. They are also used as mobile sensors, illumination sensors, hazardous materials approach prevention sensors, speed measurement sensors and level (level) sensors. The infrared sensor is used for apartment entrance and intrusion detection in the temperate region, and the ultrasonic sensor is used for the car rear.

RF sensors using the microwave band can detect distances of about 12 to 20 meters, and the sensing angle is about 90 degrees. When the RF sensor is used as the illumination sensor, the sensing range and the sensing angle are different for each RF sensor, so it is necessary to use the sensing range separately for the near range, the middle range, and the far range.

However, since the motion detection sensor including the RF sensor can not accurately know the distance information including the sensing distance and the sensing angle of the sensor, it is inevitable that the installation position of the sensor is arbitrarily selected and installed by the operator. Therefore, There is a problem that the reliability of the system can be reduced.

Usually, the motion detection sensor is released with the detectable distance. However, there is a failure rate of the sensor malfunction or the detectable distance when the actual sensor is installed and used. Therefore, the user who uses the motion sensor needs to check the accurate effective distance information of the sensor according to the installation position or purpose of the sensor.

According to the present invention, it is possible to test the motion detection performance of a moving body by the distance of the motion detection sensor through wireless communication regardless of the installation position of the motion detection sensor, and simultaneously perform the distance movement and the detection performance test The present invention provides a portable test apparatus of a motion detection sensor that can easily perform a test operation and accurately confirm effective sensing distance information of a motion sensing sensor by distance.
