The indoor communication network 2 includes three types of nodes: a positioning node 21, a parking space detection node 22, and a wireless router 23.
[0057] The positioning node 21 is an LED lighting device (such as an LED fluorescent lamp) distributed in a parking lot, which periodically emits a positioning signal.

[0058] The wireless router 23 can upload the parking space status detected by the parking space detection node 22 to the data processing center 4.
[0059] The parking space detection node 22 is a parking space detector set at a corresponding position (for example, above the parking space) of the parking space, which detects the parking space status (empty or existing) and sends the detected parking space status information to the wireless router 23.
[0060] image 3 It is a schematic diagram of the circuit structure of an exemplary parking space detector. In this embodiment, the parking space detection node 22 is implemented in the form of an LED fluorescent lamp, which includes a tube body structure and a circuit structure arranged in the tube body structure. The circuit structure includes: a light source module 221 for providing illumination; a fluorescent lamp power module 222, used to provide DC supply for the light source module 221; Bluetooth module 223, which is connected to the fluorescent lamp power module 222, the fluorescent lamp power module 222 obtains the DC supply, and can control the fluorescent lamp power module 222 to provide the DC supply to the light source module 221, which It can communicate with external devices (for example, the mobile terminal 20); and the ultrasonic ranging module 224, which is connected to the Bluetooth module 223, can be controlled by the Bluetooth module 223 to perform ranging, and report the ranging result to the Bluetooth module 223, and then It is delivered to the external device by the Bluetooth module 223.
[0061] A signal line is provided between the Bluetooth module 223 and the fluorescent lamp power module 222, and the Bluetooth module 223 controls the direct current supply provided by the fluorescent lamp power module 222 to the light source module 221 through this signal line. There are two signal lines between the Bluetooth module 223 and the ultrasonic ranging module 224. The Bluetooth module 223 provides a trigger signal through one of the two signal lines to notify the ultrasonic ranging module 224 to perform ranging, and through the two signal lines The other obtains the ranging result. In this embodiment, the ranging result is a square wave signal, and the effective level width of the square wave signal is proportional to the ranging distance. The effective level width of the trigger signal is not less than 10 microseconds. The Bluetooth module 223 can compare the distance measurement result with the set threshold to determine whether there is a vehicle in the set parking space; and the Bluetooth module 223 controls the fluorescent lamp power supply module 222 according to the judgment.

[0062] The ultrasonic ranging module 224 includes an electro-acoustic transducer for transmitting ultrasonic waves; an acousto-electric transducer for receiving ultrasonic echoes; and an echo processing circuit for giving the detection result when the echo is detected .
[0063] It is worth mentioning that the above-mentioned parking space detection node 22 also has a positioning node 21. Specifically, by cleverly adding a Bluetooth module 223 connected to the fluorescent lamp power module 222, the Bluetooth module 223 can be connected to an external device (for example, other parking spot detection nodes 22, positioning nodes 21, or wireless routers 23). Provide positioning; and, by adding an ultrasonic ranging module 224 connected to the Bluetooth module 223, the parking space detection function can be realized; in addition, according to the parking space detection result, the Bluetooth module 223 can also control the direct current supply provided by the fluorescent lamp power module 222 to the light source module 221 , Realize the dimming of the light source module 221. In addition, in this embodiment, the wireless communication function is implemented by the Bluetooth module 223. In other embodiments, the Bluetooth module 223 may also be replaced with other forms of wireless communication methods, such as WiFi.
[0064] It can be understood that, for the physical realization of the positioning node 21, the ultrasonic ranging module 224 in the parking space detection node 22 described above can be omitted. For the physical realization of the wireless router 23, the ultrasonic ranging module 224 in the parking space detection node 22 mentioned above can be omitted. In other words, the positioning node 21/wireless router 23 can be implemented in the form of an LED fluorescent lamp, which includes a tube structure and a circuit structure arranged in the tube structure.

The navigation information includes parking lot map + allocated parking space location, so that the user can use the positioning node 41 in the indoor communication to find the allocated parking space.
[0067] It is worth mentioning that the three types of nodes 21, 22, and 23 in the indoor communication network 2 are only divided from the functional configuration of the network. In terms of specific physical implementation, the three types of nodes can adopt the same structural form. For example: these three types of nodes 21, 22, 23 can all be used image 3 The form of LED fluorescent lamp shown.

[0069] S51: When the vehicle enters the parking lot, the gate control unit 3 reads the vehicle information and/or the user's identity information and uploads the read information to the data processing center 4. Among them, the user identity information can be provided by the user's mobile terminal 20 (for example, a mobile phone or a tablet computer, etc.), and the vehicle information can be provided by an ETC on the vehicle.
[0070] S52: The data processing center 4 judges whether a parking space has been reserved for the user, and if so, directly proceeds to step S54, otherwise, proceeds to step S53.

[0072] S54: The data processing center 4 generates a parking space navigation map (parking lot map + parking space location) and sends it to the mobile terminal 20 of the user; or the data processing center 4 sends the allocated parking space to the mobile terminal 20 of the user, and the mobile terminal of the user The APP on 20 generates the parking space navigation map by itself according to the allocated parking space.
[0073] S55: The positioning node 21 periodically transmits positioning signals, so that the mobile terminal 20 of the user entering the parking lot can determine the vehicle position in real time when the vehicle is in motion, and find the allocated parking space according to the navigation map.
[0074] S56: When the vehicle enters the parking space, the parking space detection node 22 detects that the parking space is occupied and uploads the parking space status to the data processing center 4 via the wireless router 23.
[0075] Image 6 It is a schematic flowchart of the reverse car searching method according to the third embodiment of the present invention. The method is implemented by the aforementioned system 10, which roughly includes the following steps:
[0076] S61: The positioning node 21 transmits a positioning signal, so that the current location of the user's mobile terminal 20 can be determined.
[0077] S62: The data processing center 4 receives a reverse car search request from the mobile terminal 20 of the user. The request includes user identity information (or vehicle information) and current location (determined by the received positioning signal). The current position can be replaced by the received positioning signal, because the positioning signal may contain the ID information of the positioning node 21.
[0078] S63: The data processing center 4 determines the location of the parking space according to the identity information, and determines the current location of the user's mobile terminal 20 according to the positioning signal, and then generates a parking space navigation map and sends it to the user's mobile terminal 20.
[0079] S64: The positioning node 21 transmits a positioning signal, so that the user can find his own vehicle according to the positioning signal and the parking navigation map provided by the mobile terminal 20.
[0080] S65: After the vehicle leaves the parking space, the parking space detection node 22 detects that the parking space is empty and uploads the parking space status to the data processing center 4 via the wireless router 23.
[0081] S66: When the vehicle leaves the parking lot, the gate control unit 3 reports the information to the data processing center 4.
[0082] S67: The data processing center 4 generates parking billing data.
[0083] S68: Perform fee deduction operation.
[0084] Figure 7 It is a schematic flowchart of the reverse car searching method according to the fourth embodiment of the present invention. The method is implemented by the aforementioned system 10, which roughly includes the following steps:
[0085] S71: The positioning node 21 transmits a positioning signal so that the current location of the user's mobile terminal 20 can be determined.
[0086] S72: The positioning node 21 transmits a positioning signal so that the user can find it according to the positioning signal on the mobile terminal 20 and the parking space navigation map (when parking, the parking space navigation map has been sent from the data processing center 4 to the user's mobile terminal 20) Own vehicle.
[0087] S73: After the vehicle leaves the parking space, the parking space detection node 22 detects that the parking space is empty and uploads the parking space status to the data processing center 4 via the wireless router 23.
[0088] S74: After the vehicle leaves the parking lot, the gate control unit 3 reports the information to the data processing center 4.
[0089] S75: The data processing center 4 generates parking billing data.
[0090] S76: Perform a fee deduction operation.
[0091] It is worth mentioning that, considering that the parking lot is generally large, the user is not familiar with the terrain, which will make it difficult to find a car. The above two reverse car searching methods proposed by the present invention can solve this problem well. In addition, there are many ways to deduct fees, such as: deduction from the user's prepaid account, the user pays cash at the exit of the parking lot or the payment window, or electronic payment such as Alipay and WeChat Pay.
[0092] In addition, considering that the construction of the indoor communication network 2 in the system 10 of the present invention is mainly based on lighting devices with wireless communication modules, it can be understood that the specific area referred to in the parking lot management system of the present invention also includes the aforementioned "indoor" Some non-indoor places that can be suitable for installing lighting devices are not covered. For example, the specific area can be: an open field (with or without gates) equipped with multiple lighting devices, such as: public squares , Parks, construction sites, and farms and mining areas for surface operations.
[0093] Although some aspects of the present invention have been presented and discussed, those skilled in the art should realize that changes may be made to the above aspects without departing from the principle and spirit of the present invention. Therefore, the scope of the present invention will be determined by the claims and The equivalent content is limited.
