An empty spacing stall information publishing device comprises a supersonic wave receiver configured to receive sound waves emitted by a supersonic wave emitter, a demodulation chip configured to convert signals, a power supply configured to supply power to a circuit, a display screen configured to display the number of empty spacing stalls, and a wifi module in parking lot. The demodulation chip,the display screen, the power supply and the wifi module are electrically connected with the controller. The empty spacing stall information publishing device is reasonable in design, simple in structure, convenient and rapid in operation and can perform processing of supersonic waves of the supersonic wave emitter so as to allow people who need parking to timely understand whether there is an empty parking stall or not, and therefore, the same is saved, the trouble of searching a parking stall is omitted, the empty spacing stall information publishing device can provide this service for a lot of drivers, is convenient to use, simple in manufacturing and low in cost and can be popularized and used.
Description
technical field [0001] The invention relates to an information announcement device, and specifically designs an empty parking space information announcement device. Background technique [0002] With the development of the economy and the improvement of people's living standards, the number of private cars is also increasing, and many people like to drive when they go out. It is true that driving a private car also provides a lot of convenience to everyone to a certain extent, but driving in the city is easy and difficult to park, and it often takes a long time to find a parking space. Discovering that the parking space is full is not only a hassle but also a delay in life. There is an urgent need for a device that can solve this problem, allowing car owners to find out if there is an empty space outside the parking lot. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an vacant parking space information announcement device to solve th...
