[Embodiment] In order to give your reviewer a better understanding of the structural features and efficacies of the present invention, please refer to the preferred embodiment and the detailed description, as described later. The first and second figures are schematic views of one embodiment of a parking space sensing device of the present invention. At the same time, please refer to the second figure, which is a schematic diagram of a consistent embodiment of the monitoring device and the parking space display electronic signage of the present invention. As shown, the parking space sensing device 1 of the present invention senses whether a single parking space 32 of a parking lot 30 has a vehicle parked. The parking space sensing device 10 is provided with a light emitting unit 12, a reflecting component 14, a light sensing unit 16, and a driving control circuit 18 in each parking space 32, wherein the light emitting unit 12 is located at the parking space 32. In contrast, the reflective element 14 is disposed on the parking space 32 and is located on the traveling path of the light emitted by the light emitting unit 12. The light sensing unit 16 is located on the traveling path of the light reflected by the reflective element, and the driving control circuit 18 is driven. The light emitting unit 12 and the light sensing unit π are coupled. The drive control circuit 18 drives the light emitting unit 12 to emit a light to the reflective element μ located on the parking space 32. The reflective element 14 reflects the light emitted by the light emitting unit 12 to the light sensing unit 16 to sense the parking space 32. status. In the above, as shown in FIG.

However, when a vehicle is parked in the parking space 32, the light sensing unit 16 will not generate the first sensing signal or generate the second sensing signal to drive the driving control circuit 18 to determine that the parking space 32 has the vehicle parked, and the first transceiver unit 182 The launch parking space 32 has the judgment result of the vehicle parking to the second transceiver unit 2〇2, so that the vehicle = 1333636. 20 shows that the vehicle is parked in the parking space 32. Thus, the parking space sensing device 10 of the present invention provides a place for the public to immediately know whether the parking space 32 has a vehicle to obtain a vacancy. Among them, the line AA indicates the roof of the vehicle. When a vehicle is located on the parking space 32, the vehicle • will reflect or scatter the light of the button 12, that is, the light will be reflected or scattered at the position of the line AA, causing the light sensing unit to sense 6 The light sensing unit 16 receives the light whose light intensity is lower than the weight of the door, and the light intensity received by the light sensing unit 16 is low. When the threshold value is reached, the drive control circuit 18 determines that the parking space is parked according to the sensing result of the light sensing unit 16. • Therefore, the present invention is a novelty, progressive and available for industrial use.
