there are 197 countries in the world. large countries span thousands of miles and small countries take hundreds of steps. some of these countries face each other across the sea and some are connected by land. a wall, a net, or even a line that divides two countries. china, regardless of its territory or population, is a well deserved big country in the world. it has a long border, many neighbors and naturally many border ports. the frontier guard is the most important thing. the stability of the country depends on him and the stability of the society depends on him. whether it is war, smuggling or smuggling, we need to pass this pass first. how to open the window and prevent flies from coming in depends on the screen. the frontier guard is this "screen". now, the micro earthquake life detector has also become a "screen".
microseismic life detector is a kind of equipment that uses microseismic sensing signal to detect the people hidden in the car. when someone is hidden in the car, the heart of the hiding person will beat rhythmically. this vibration will be transmitted to the bottom of the car and the support system. the vibration will be collected and transmitted back to the system through the data cable by connecting the sensor with the tested car, based on this vibration analysis, whether someone exists is displayed on the display terminal, accompanied by audible and visual alarm. this kind of detection is passive and does not emit radioactive substances harmful to human body. it is placed at the border and is an expert in dealing with illegal immigration. the microseismic life detector was unveiled at a port two days ago.
