In order to explain the technical features of the present invention in detail, the following preferred embodiments are described in conjunction with the drawings as follows, wherein:

As shown in FIG. 1 to FIG. 2, a roadside parking grid management system 10 provided by a preferred embodiment of the present invention is mainly composed of a server 11 and a toll collector handheld device 21, of which:

The server 11 stores therein a parking grid database 12 which is established in advance. The parking grid database 12 has a plurality of parking grid data 13. Each of the parking grid data 13 includes a parking grid number, parking grid coordinates, and parking grid. Corresponding road names and information on whether parking spaces are used. The aforementioned parking grid coordinates are the GPS (Global Positioning System) average coordinates of the corresponding parking grid, that is, the averaged GPS coordinates of the four corners of the parking grid, which is the center of the parking grid. The coordinates of the point; in addition, the aforementioned parking grid coordinates may also be the coordinates of a fixed corner of the parking grid, and this fixed corner may be the left front corner designated as the driving direction of the road. It can be seen that the coordinates of the parking grid can be any position in the parking grid, as long as it can correspond to the corresponding parking grid.

The toll collector handheld device 21 has a camera module 22, a display module 23, and a positioning module 24. The display module 23 displays the location of the toll collector handheld device 21 and the parking space in a map manner. At least part of the information in the database 12, the positioning module 24 is used to obtain the current coordinates of the toll collector handheld device 21, the toll collector handheld device 21 is installed with a parking registration software 26, the parking registration software 26 is held by the toll collector When the device 21 is executed, the display module 23 is provided with an operation interface 27 for toll collectors to operate, and the camera module 22 is used to take pictures of vehicles in a parking grid, and then obtain a license plate image 221, and The current coordinates at the time of shooting are defined as the shooting coordinates, and the toll collector handheld device 21 obtains the parking grid coordinates of the parked vehicle through a calculation logic 211 based on the shooting coordinates. It should be added that the parking grid coordinates referred to in the previous paragraph can also be the average value of the shooting coordinate values accumulated after the toll collector has taken photos of the parking grid multiple times. This average value is mainly for the convenience of the shooting coordinates. For comparison, if the parking grid coordinates are set to this average value, the parking grid coordinates can be obtained without using the aforementioned calculation logic 211.

In this embodiment, the positioning module 24 is a global positioning system (GPS), and the geographic coordinates are obtained by satellite positioning. The display module 23 is a display screen, and the camera module 22 is camera. When the display module 23 displays at least part of the information in the parking grid database 12, it displays at least the road name, the plural parking grids within a predetermined distance near the toll collector handheld device 21, and the use status of each of the parking grids. . Since the toll collectors usually register the vehicles on the parking grid along one side of the road when they are billing, this predetermined distance can generally be set to 20 meters, which is enough. Shows about 6-8 parking spaces near toll collectors.

As shown in Figure 3, the license plate is usually located at the front or rear of the vehicle. Therefore, when the toll collector is shooting the license plate, in order to be able to capture the license plate, it is practically impossible for the toll collector to stand in the parking space where the vehicle is parked. , But standing in front of or behind the outside of the parking bay to photograph the license plate at the front or rear of the vehicle. Furthermore, it can be known that the shooting coordinates are usually not located in the parking grid where the vehicle being parked, but in front or behind the outside of the parking grid. Based on this consideration, the calculation logic 211 of the present invention is to take a parking grid coordinate that is more than 1 meter away from the shooting coordinate, and select the parking grid corresponding to this parking grid coordinate as the parked vehicle. Parking grid.

As shown in FIG. 4, the toll collector handheld device 21 transmits the license plate image 221 and the coordinates of the parking grid where the photographed vehicle stops to the server 11 via a wireless network. The server 11 compares the parking grid coordinates in the parking grid database 12 with the parking grid coordinates of the photographed vehicle, and updates the parking grid data 13 corresponding to the matching parking grid coordinates to State that parking grid is used. In addition, the server 11 also uses the image recognition technology to identify the license plate number of the license plate image 221, and transmits the recognized license plate number to the toll collector handheld device 21 for confirmation by the toll collector. In actual use, the data collected by the toll collector's hand-held device 21 to the server can be more, for example, it can include the current parking ticket billing record, next billing time, estimated parking time, and departure time. And unused parking bay numbers. Among them, the billing record and billing time are related to the billing behavior of the toll collector, and the estimated parking time and departure time can be manually entered. As for the unused parking box number, it can be manually entered or It is determined that there is no car number by photographing an unused parking grid, and then it is determined that there is no vehicle parked, and it is determined to be an unused parking grid, and the parking grid number is identified by the parking grid coordinates of the parking grid.

The architecture of this embodiment has been described above, and the use status of this embodiment will be described next.

Before the toll collector has started to register the parking grid, the parking grid database 12 in the server 11 is in an unused state.

As shown in Figures 3 to 4, when the toll collector registers and bills the parking space, the operator operates the operation interface 27 in front of the parking space where the vehicle is parked (the rear can also be an example here) to check the vehicle. The front license plate is photographed to obtain a license plate image 221. At the same time, the toll collector handheld device 21 also obtains the current shooting coordinates through the positioning module 24 and records the current shooting coordinates as the shooting coordinates of the license plate image 221. In addition, the toll collector handheld device 21 also obtains the coordinates of the parking grid where the vehicle is parked by photographing the coordinates. The toll collector handheld device 21 then transmits the license plate image 221 and the parking grid coordinates of the vehicle being parked to the server 11 via a wireless network. In addition, the toll collector handheld device 21 can also send the parking ticket billing record, the next billing time, the estimated parking time, the departure time, and the unused parking slot number to the server according to the preset settings. .

After receiving the data from the toll collector's handheld device 21, the server 11 compares the parking grid coordinates in the parking grid data 13 with the parking grid coordinates of the photographed vehicle, and uses image recognition. Technology to identify the license plate number on the license plate image 221, and transmit the recognized license plate number to the toll collector handheld device 21 for confirmation by the toll collector. In addition, the status of the parking grid corresponding to the matching parking grid coordinates is updated to be in use, and the received data is integrated to achieve the effect of managing each parking grid.

When the vehicle leaves the parking space, the toll collector only needs to take another picture of the parking space. Since the captured image does not have a license plate, there is no license plate number. Without a license plate number, the toll collector can only hold the device 21 Send the image, shooting coordinates, and parking grid coordinates to the server 11. After receiving the data, the server 11 can judge that the parking grid is no longer in use by the aforementioned method of comparing coordinates, and stop at the parking The grid database 12 updates the status of the parking grid to unused.

In addition, if another vehicle is parked after the vehicle leaves, a different license plate number will occur when the camera gets the license plate number, which means that the previous vehicle has left and the current vehicle is parked in the In the parking grid, the current license plate number of the car is used as the billing object. Since the data transmitted to the server contains the coordinates of the parking space and the license plate number, the server can determine that the previous car has not parked in this parking space, and charge the newly parked vehicle. And it is maintained that the parking grid is in use.

And because each parking grid has its corresponding road name, the usage status of each parking grid can be combined with the road name to form enough parking grid information for ordinary people to understand a certain road section. In actual implementation, the coordinates of each of the roads may also be entered into the parking grid database 12 together with the plurality of parking grid data 13.

It can be known from the above that the present invention can manage the use status of each parking grid and confirm the coordinate position and road section corresponding to each parking grid, which is sufficient to provide sufficient information for parking grids and corresponding road sections for general users.

As shown in Figure 5, it must be added that the information contained in the parking grid database 12 of the server 11 can further cooperate with the current smart phones to provide graphical information to make it easier for users to understand parking. Grid of information. For example, the system of the present invention may further include a consumer software 31, which is installed on a consumer handheld device 32 (taking a smart phone as an example), and the consumer handheld device 32 executes the consumer The software 31 accesses the parking grid database 12 of the server 11 via a wireless network, and displays the information contained in the parking grid database 12 on the consumer handheld device 32.

As shown in Figure 6, the map is the easiest to understand when displayed, and the displayed content must at least show the road and its name, the parking bay next to the road, and each The usage status of the parking bay. What is shown in Figure 6 is the road and the parking grid P next to the road. The hollow parking grid P is unused, and the solid parking grid P is in use (that is, occupied by a vehicle). The display mode allows users to easily understand the use of parking grid P on this road section.

Based on the above, it can be known that the present invention can not only manage the use status of each parking grid and confirm the coordinate position and road section corresponding to each parking grid, but also the general user can install the consumer software 31 to access the server The parking grid database 12 in 11 displays each parking grid information on the consumer handheld device 32 in the form of a map, so that ordinary consumers can easily understand.
