In the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other, and the scope of protection of the present application is not limited to the following.

[0029] As shown in Figures 1 to 5 The present embodiment provides a parking guidance device for a relatively dark environment, which comprises a garage controller 1, an optical projection device 2 and an ambient brightness sensor 3. The garage controller 1 is arranged on an upright, and the top of the upright is provided with a beam body. The optical projection device and the ambient brightness sensor are both wirelessly connected to the garage controller.

[0030] Specifically, in the present embodiment, the upright comprises a left front upright 4, a left rear upright 5, a right front upright 6 and a right rear upright 7. The left front upright 4 and the left rear upright 5 are opposite in position, and the right front upright 6 and the right rear upright 7 are opposite in position. The left front upright 4 corresponds to the right front upright 5 in position. The beam body comprises a front upper crossbeam 8, a rear upper crossbeam 9, a right upper longitudinal beam 10 and a left upper longitudinal beam 11. One end of the front upper crossbeam 8 is fixed to the top end of the left front upright 4, and the other end is fixed to the top end of the right front upright 6. The two ends of the rear upper crossbeam 9 are connected to the top ends of the left front upright 4 and the right front upright 6, respectively. The two ends of the left upper longitudinal beam 11 are fixedly connected to the top ends of the left front upright 4 and the left rear upright 5, respectively. The two ends of the right upper longitudinal beam 10 are fixedly connected to the top ends of the right front upright and the right rear upright, respectively. The plate body 12 is arranged between the longitudinal beams and the crossbeams. The parking space in the present embodiment is composed of the upright, the crossbeams, the longitudinal beams and the plate body to form a parking space frame support structure.

[0031] The optical projection device 2 comprises a plurality of light beam guiding devices installed on the beam body at the top of the column, which emit guiding light beams to the ground of the parking space, and the ambient brightness sensor is arranged on the column of the parking space to detect the ambient brightness information of the parking space and send the collected information to the garage controller.

[0032] Specifically, the garage controller 1 in the embodiment is arranged on the left front column 4, and is composed of a Siemens S7 series PLC, including an input / output signal module, an Ethernet communication module, and a power module. The ambient brightness sensor is arranged on the right front column, which detects the ambient brightness of the parking space and transmits the detected ambient brightness information to the input / output module of the garage controller. The garage controller analyzes the ambient brightness data through the CPU of the PLC, and controls the optical projection device to emit guiding light beams to both sides of the ground of the garage according to the data analysis result.

[0033] The optical projection device 2 selects optical projectors, and a plurality of optical projectors are arranged on the right upper longitudinal beam 10 and the left upper longitudinal beam 11. The number of optical projectors arranged on the right upper longitudinal beam 10 and the left upper longitudinal beam 11 is equal, and the positions of the optical projectors arranged on the two longitudinal beams are opposite. The optical projection device is used to receive the control signal of the garage controller, can project guiding light beams on the ground (or the vehicle plate), and the vehicle driver can adjust the position of the vehicle according to the projected guiding light beams. The light beam mainly guides the driver to place the vehicle in the center, so that the left and right positions of the vehicle cannot deviate too much.

[0034] Specifically, once the ambient brightness of the parking space is low, the garage controller 1 sends an opening signal to the optical projection device 2 according to the ambient brightness signal of the ambient brightness sensor 3, and the optical projector projects left guiding light beams 13 and right guiding light beams 14 on the ground (or the vehicle plate) under the control of the garage sensor. The light beams emitted by the optical guiding device need to meet the requirements of bright color and wide beam band for easy observation by the driver. The left guiding light beam and the right guiding light beam only guide the driver to park the vehicle in the appropriate position. The light beam only has a guiding effect and does not have a detecting effect. The driver can better park the vehicle in the designated parking area by guiding the driver to park the vehicle in the designated parking area.

[0035] A voice prompting device 15 wirelessly connected to the garage controller 1 is also arranged. The voice prompting device selects a loudspeaker, which is arranged on the right front column 6 of the parking space and can broadcast vehicle information data through the loudspeaker. The voice prompting device can prompt the driver about the over-limit fault of the vehicle during the reversing process and the large deviation of the left and right positions of the vehicle. In the embodiment, the number of loudspeakers is determined according to the actual needs.

[0036] In addition, in order to better determine whether the vehicle exceeds the range of the guide light beam during the reversing into the garage process, the embodiment also includes an ultra-wide photoelectric detection device electrically connected with the garage controller. The ultra-wide photoelectric detection device selects a pair of wave detection devices, which includes a signal emitting part 16 and a signal receiving part 17. The signal emitting part and the signal receiving part are paired two by two. The signal emitting part 16 includes a first signal emitting part 18 and a second signal emitting part 19. The first signal emitting part 18 is vertically arranged on the left side of the front upper cross beam 8, and the second signal emitting part 19 is vertically arranged on the right side of the front upper cross beam 8. The first signal receiving part and the second signal receiving part are distributed in a left-right position on the front upper cross beam. The signal output ends of the first signal emitting part and the second signal emitting part are directed towards the ground of the parking space, and both are parallel to the left front upright column.

[0037] The signal receiving part is paired two by two with the signal emitting part, so the signal receiving part 17 in the embodiment includes a first signal receiving part 20 and a second signal receiving part 21. The first signal receiving part 20 and the second signal receiving part 21 are both fixedly arranged on the ground of the parking space. The first signal receiving part 20 is arranged on the outer side of the left guide light beam 13 and corresponds to the first signal emitting part 16 arranged above and below. The second signal receiving part 21 is arranged on the outer side of the right guide light beam 14 and corresponds to the second signal emitting part 19 arranged above and below. Specifically, in the embodiment, the position of the pair of detection devices is compared with the fiber beam emitted by the optical guide device. The first signal receiving part is located on the left side of the left guide light beam, 50 mm away from the left guide light beam. Similarly, the second signal receiving part is located on the right side of the right guide light beam, 50 mm away from the right guide light beam. If the vehicle is parked with a large deviation from the guide light beam, the voice prompt device will be triggered, the speaker device will be alarmed through the garage controller, and the driver will be prompted through the sound that the vehicle is ultra-wide on one side, so as to guide the driver to adjust the position of the vehicle.

[0038] In order to make the driver accurately get the parking end position, the embodiment is further provided with a vehicle stopper 22 at the rear side of the parking space, the vehicle stopper 22 adopts the speed bump with the protruding structure commonly used on the road, the number of the speed bump is two, one is arranged at the left side of the rear side of the parking space and the other is arranged at the right side of the rear side of the parking space, the position of the speed bump coincides with the final position of the vehicle completing the reversing, since the protruding structure exists on the speed bump on the left side and the speed bump on the right side, once the rear wheel of the vehicle contacts with the speed bump, the driver in the cab will receive the signal, the signal is similar to that when the vehicle passes through the speed bump on the road, the driver will operate the vehicle to realize parking at this time, in order to better trigger the left and right side ultra-wide photoelectric detection devices, the embodiment is further provided with a pressure sensor 23 on the speed bump, the pressure sensor 23 is wirelessly connected with the garage controller, the pressure sensor is used to detect the pressure change when the rear wheel of the vehicle contacts with the speed bump, when the pressure sensor receives the pressure signal, it will send the signal to the garage controller, the garage controller is used to control the normal operation of the left and right side ultra-wide photoelectric detection devices.

[0039] The working principle of the detection device arranged in the embodiment is as follows: taking the left side ultra-wide photoelectric detection device as an example, the signal channel exists between the first signal sending part and the first signal receiving part of the detection device, when the vehicle completes parking, if the vehicle is placed in the center, that is, the left and right positions cannot be too large, under the condition that the vehicle is in this state, the first signal receiving part of the ultra-wide photoelectric detection device can receive the signal sent by the first signal sending part, the garage controller will not receive the over-limit signal; if the vehicle in the parking state exceeds the range of the guide light beam, that is, the left and right positions are too large, at this time, one side of the left and right sides of the vehicle will inevitably block the above-mentioned signal channel, the first signal receiving part of the ultra-wide photoelectric detection device will not receive the signal sent by the first signal sending part, the detection device will immediately send the vehicle over-limit fault signal to the garage controller, the garage controller will remind the driver that the vehicle position is too large through the loudspeaker, and guide the driver to re-adjust the position of the vehicle.

[0040] Although the specific embodiments of the utility model have been described in combination with the drawings, it is not a limitation on the protection scope of the utility model, and those skilled in the art should understand that various modifications or changes made by those skilled in the art on the basis of the technical scheme of the utility model without creative labor are still within the protection scope of the utility model.
