With the car gradually into the common people's home, we enjoy more convenient, free travel at the same time, the wheel of the trouble is also more and more. Before the “expensive car”, “traffic trouble”, after the “parking difficult” to countless car lovers heartbreak. But people's demand for motor vehicle parking space continues to rise, China's car ownership has more than 300 million, ranking first in the world. However, the supply side of the parking infrastructure is insufficient, far from keeping up with the continuous growth of automobile consumption, resulting in a more prominent contradiction between parking supply and demand.

According to the National Parking Analysis Report, more than 1 million parking lots have been built in China, but compared with the huge car ownership, parking spaces are still in short supply. In order to enhance the convenience of residents' parking, improve the utilization rate of urban land, enhance the city image, etc., three-dimensional parking lot came into being in response to the need; so that many of the original can only stop 20 cars on the site, with more than ten times the number of parking spaces, complete a more efficient use of urban space, and promote the city's parking into the era of wisdom!

A limit switch is installed in each parking space to detect whether the panning movement of the carrier plate is in place when the carrier plate is panning movement. Shielded proximity switches TYF12 series can be used here, with a long detection distance and a switching frequency of 800Hz, which can guarantee a sufficient safety distance for the moving mechanism.
