[0065] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0066] Example 1

[0067] Figure 1 The flowchart of the method for detecting a parking space with a single card on three networks is shown in FIG. 1 . In an embodiment of the present invention, a method for detecting a parking space with a single card on three networks is provided. The method includes:

[0068] Step S100: regularly receiving the parking space status containing time information uploaded by the geomagnetic terminal;

[0069] The geomagnetic terminal can obtain the usage status of parking spaces in real time and sense the entry and exit of vehicles;

[0070] Step S200: acquiring video information according to a preset inspection rule, and determining a reference state of each parking space according to the video information;

[0071] On the one hand, the inspection end can autonomously obtain the usage status of each parking space at intervals, and on the other hand, it serves as a data transfer end for the geomagnetic end signal. The geomagnetic end first caches the acquired information locally, and when the signal is good, the acquired information is sent to the inspection end. At this time, the data transmission pressure of the geomagnetic end is extremely small, and there will be no waste of resources due to real-time search for signals.

[0072] Step S300: Counting the parking space status of the geomagnetic end and comparing it with the reference status, and locating the abnormal geomagnetic end according to the comparison result;

[0073] By comparing the parking space status obtained by the geomagnetic terminal itself and the reference status obtained by the inspection terminal, the working condition of the geomagnetic terminal can be determined, and then some abnormal geomagnetic terminals can be identified;

[0074] Step S400: Sending an emergency instruction to the abnormal geomagnetic end;

[0075] Each geomagnetic terminal has a built-in reset module or self-check module. When an emergency command is received, it can at least execute the reset module and perform self-check on the problem.

[0076] The geomagnetic terminal has a built-in triple-network card to obtain the signal quality of network operators in real time and select the target operator based on the signal quality;

[0077] For the above geomagnetic terminal, further explanation is needed. This product is aimed at roadside parking application scenarios. The function of the geomagnetic device is to sense the vehicle entering and exiting the parking lot, record the entry and exit time, and then send relevant timing signals. The disadvantage of the traditional single-network geomagnetic is that if a certain operator is used, if the signal in some areas of the city is not good, it will continue to search and send signals, which consumes a lot of power and there is packet loss. Using a single card for three networks can effectively solve this problem. If the signal of the main card is not good, it will automatically switch to other operators' signals.

[0078] As a preferred embodiment of the technical solution of the present invention, the step of obtaining the parking space status by the geomagnetic terminal includes:

[0079] Real-time monitoring of environmental parameters, and adjustment of radar detection algorithms according to the environmental parameters;

[0080] Based on the radar detection algorithm, the motion parameters of the vehicle are acquired in real time, and the parking space status is determined according to the motion parameters; the parking space status contains time information;

[0081] The radar detection algorithm is built into the radar module. The function of the radar module itself is to obtain motion parameters. You can just select a finished radar module; based on the radar module, you can easily obtain the usage status of the parking space.

[0082] It is worth mentioning that not only the radar module can complete the process of judging the parking space usage status, but even some ranging sensors are sufficient to perform the above functions.

[0083] The signal quality of three network operators is obtained regularly. When the signal quality of any network operator meets the preset signal condition, the corresponding network operator is selected as the target operator.

[0084] Signal conditions generally include two dimensions: signal transmission speed and signal transmission stability.

[0085] Pack the parking space status and send it to the transfer end based on the selected target operator.

[0086] Furthermore, the step of periodically acquiring the signal qualities of the three network operators and selecting the corresponding network operator as the target operator when the signal quality of any network operator meets the preset signal condition includes:

[0087] Obtain the signal quality of three network operators in real time and compare the signal quality with the preset signal conditions;

[0088] When the signal quality of any network operator meets the preset signal condition, the corresponding network operator is selected as the target operator;

[0089] When the signal quality of any network operator does not meet the preset signal conditions, record the duration;

[0090] When the signal quality of any network operator meets the preset signal conditions, the data transmission process is executed. When a network operator does not meet the signal conditions all the time, it means that there may be an abnormal problem, so an error report is required.

[0091] Figure 2 The first sub-flow chart of the three-network single-card geomagnetic parking space detection method is as follows: the step of obtaining video information according to a preset inspection rule and determining the reference state of each parking space according to the video information includes:

[0092] Step S201: Acquire the layout information of the recorded acquisition terminal; the layout information is tabular data, and the layout information includes a number item, an initial position item, and an acquisition parameter item; the acquisition parameter includes an acquisition range and an acquisition accuracy;

[0093] The acquisition end is a video acquisition device with mobile function. The number of acquisition ends is not fixed, and one acquisition end corresponds to multiple geomagnetic ends.

[0094] Step S202: determining the inspection track of each acquisition terminal according to the arrangement information, and marking the detection segments corresponding to each local magnetic terminal in the inspection track;

[0095] Each acquisition end corresponds to multiple geomagnetic ends, and its movement trajectory (inspection trajectory) is also determined by these corresponding geomagnetic ends.

[0096] Step S203: receiving the video information and position information acquired by the acquisition terminal in real time, identifying the video information, and determining the reference state of each parking space;

[0097] By receiving the video information and location information obtained by the acquisition end and identifying the video information, the occupancy status of each parking space can be visually judged as a reference status.

[0098] Step S204: querying the corresponding detection segment according to the position information, and locating the corresponding geomagnetic end according to the detection segment; wherein each geomagnetic end contains unique tag information;

[0099] Step S205: storing a reference state according to the tag information of the located geomagnetic terminal;

[0100] The information obtained by the acquisition end at different positions corresponds to different geomagnetic ends. Accordingly, the recognition result of the video information, that is, the reference state, points to the parking space occupancy state of the geomagnetic end.

[0101] As a preferred embodiment of the technical solution of the present invention, the step of receiving the video information and its position information acquired by the acquisition terminal in real time, identifying the video information, and determining the reference state of each parking space includes:

[0102] Receive the location information obtained by the acquisition end in real time, and read the acquisition range in the acquisition parameters of the acquisition end;

[0103] Reading a standard image from a preset standard image library according to the position information and the acquisition range; the standard image is an image of a parking space when no car is parked;

[0104] Receiving the video information acquired by the acquisition end in real time, and comparing the video information with the standard image;

[0105] The reference state of each parking space is determined according to the comparison result; the reference state contains time information.

[0106] The preset standard image is queried according to the location information of the acquisition end. The standard image is pre-photographed by the staff and arranged according to the location information. When the acquisition end receives new video information, the corresponding standard image is queried according to the location information, and then the video information is compared and identified (the video information is a collection of images). According to the comparison results, it can be judged whether each parking space is occupied.

[0107] It should be noted that the standard image is an image when there is no vehicle occupying the space. As long as there is a difference between the video information and the standard image, the parking space will be regarded as occupied regardless of whether it is fully occupied or not.

[0108] In an example of the technical solution of the present invention, the step of storing the reference state according to the tag information of the located geomagnetic end includes:

[0109] Arrange the geomagnetic terminals according to the tag information of the geomagnetic terminals to establish a parking area map; the parking area map contains a database corresponding to the geomagnetic terminals one by one;

[0110] Read the reference status of each parking space in real time and insert it into the corresponding database;

[0111] The existence of data in each database is obtained based on the time axis, and an index curve is established according to the data existence; the horizontal axis of the index curve is time, and the vertical axis is a numerical value generated according to the tag information of the geomagnetic end corresponding to the database where the data exists; the data existence includes two states: existence and non-existence.

[0112] The acquisition end is moving in real time, and the detection of each geomagnetic end is intermittent. Therefore, the reference state is also the reference state of certain time periods. After receiving the video information obtained by the acquisition end, the video information is identified to determine the reference state of each geomagnetic end. At this time, the reference state of each geomagnetic end is counted to generate an index curve, which indicates when the acquisition end detects which geomagnetic end.

[0113] Figure 3 The second sub-flow chart of the three-network single-card geomagnetic parking space detection method is as follows: the parking space status of the statistical geomagnetic end is compared with the reference status, and the step of locating the abnormal geomagnetic end according to the comparison result includes:

[0114] Step S301: receiving the parking space status uploaded by the geomagnetic terminal, and reading the time period in which the corresponding geomagnetic terminal has data according to the index curve;

[0115] When receiving the parking space status uploaded by the geomagnetic terminal, firstly, the time period of the reference state corresponding to the geomagnetic terminal should be queried according to the index curve;

[0116] Step S302: intercepting the parking space status according to the time period to obtain a waiting-for-inspection status;

[0117] The time period of the reference state is a subset of the time axis of the parking space state. Therefore, the parking space state is intercepted by the time period of the reference state to obtain the state to be inspected.

[0118] Step S303: reading the reference state in the database corresponding to the geomagnetic end, and comparing the state to be inspected with the reference state;

[0119] Step S304: When the difference rate between the state to be checked and the reference state reaches a preset condition, the geomagnetic end is marked as an abnormal geomagnetic end.

[0120] Compare the state to be inspected with the reference state and calculate the difference rate. When the difference rate is small, it can be attributed to interference in the operation process of the geomagnetic end or the video recognition process. However, if the difference rate is large, for example, the geomagnetic end shows that the parking space is occupied, and the video recognition result shows that the parking space is not occupied, then the geomagnetic end needs to be marked as an abnormal geomagnetic end. Of course, there is also the possibility of errors at the acquisition end. By detecting the abnormal geomagnetic end, if there is no problem, it means that there is a problem at the acquisition end.
