In order to explain the technical features of the present invention in detail, the following preferred embodiments will be described with reference to the drawings, wherein:

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

The server 11 internally stores a pre-established parking space database 12, the parking space database 12 has a plurality of parking space data 13, each of the parking space data 13 includes a parking space number, a parking space coordinate, and a parking space. Corresponding road name and information on whether the parking space is used. The aforementioned parking space coordinates are the average coordinates of the GPS (Global Positioning System) of the corresponding parking space, that is, the average value of the GPS coordinates of the four corners of the parking space, that is, the central parking space. The coordinates of the point; in addition, the aforementioned parking space coordinates may also be coordinates of a fixed corner of the parking space, and the fixed corner may be a left front corner designated as the direction of the road. It can be seen that the parking space coordinates can be any position in the parking space, as long as it can correspond to the corresponding parking space.

The toll collector device 21 has a camera module 22, a display module 23 and a positioning module 24, and the display module 23 displays the location of the toll collector 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 configured to obtain the current coordinates of the toll collector device 21, and the toll collector device 21 is equipped with a parking registration software 26, which is held by the toll collector When the device 21 is executed, an operation interface 27 is provided by the display module 23 for the toll collector to operate, and the camera module 22 is used to take a picture of the vehicle in a parking space, thereby obtaining a license plate image 221, and The current coordinates at the time of shooting are defined as shooting coordinates, and the toll collector device 21 obtains the parking space coordinates stopped by the photographed vehicle through a calculation logic 211 based on the photographing coordinates. It should be added that the parking space coordinates referred to in the preceding paragraph may also be the average value of the photographing coordinate values accumulated by the toll collector after taking photos of the parking space multiple times. This average value is mainly for the convenience of shooting coordinates. For comparison, if the parking grid is set to this average value, the parking grid coordinates can be obtained without using the above-described calculation logic 211.

In this embodiment, the positioning module 24 is a global positioning system (GPS), and the geographic coordinate value is obtained by means of satellite positioning. The display module 23 is a display screen, and the camera module 22 is camera. When displaying at least part of the information in the parking space database 12, the display module 23 displays at least the road name, the plurality of parking spaces within a predetermined distance in the vicinity of the toll collector device 21, and the usage status of each parking space. . Since the toll collectors are mostly billing the vehicles on the parking space along the side of the road when the bill is opened, the predetermined distance can be set to 20 meters, which is sufficient for the actual situation. Shows about 6-8 parking spaces near the toll collector.

As shown in Figure 3, since the license plate is usually located at the front or the back of the vehicle, the toll collector cannot actually stand in the parking space where the vehicle is parked in order to be able to capture the license plate when shooting the license plate. Instead, the license plate of the front or rear of the vehicle is photographed in front of or behind the outside of the parking space. Furthermore, it can be seen that the photographing coordinates are usually not located in the parking space stopped by the photographed vehicle, but in front of or behind the parking compartment. Based on this consideration, the calculation logic 211 of the present invention is: taking a parking space coordinate that is more than 1 meter away from the shooting coordinate, and selecting the parking space corresponding to the parking space coordinate as the stopped by the photographed vehicle. Parking space.

As shown in FIG. 4, the toll collector device 21 transmits the license plate image 221 and the parking space coordinates stopped by the photographed vehicle to the server 11 by the wireless network. The server 11 compares the parking space coordinates in the parking space database 12 with the parking space coordinates stopped by the photographed vehicle, and updates the parking space data 13 corresponding to the matching parking space coordinates to The state in which the 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 identified license plate number to the toll collector device 21 for confirmation by the toll collector. In actual use, the data collected by the toll collector handheld device 21 to the server may be more, for example, may include the parking ticket opening record of the current day, the next billing time, the estimated parking time, and the departure time. And the unused parking number. Among them, the billing record and billing time are related to the billing behavior of the toll collector. The estimated parking time and departure time can be manually input. If the parking grid number is not used, it can be manually input or It is determined by photographing the unused parking space to determine that there is no car number, and then judging that no vehicle is parked, and determining that it is an unused parking space, and identifying the parking space number by the parking space coordinates of the parking space.

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

Before the toll collector has started to register the parking space, the state of all the parking spaces in the parking space database 12 in the server 11 is unused.

As shown in Figures 3 to 4, when the toll collector performs the registration of the parking space, the operator interface 27 is operated in front of the parking space where the vehicle is parked (the rear can also be exemplified here). The front license plate is photographed to obtain a license plate image 221, and at the same time, the toll collector device 21 obtains the current photographing coordinates by the positioning module 24 and records the photographed coordinates of the license plate image 221 . In addition, the toll collector device 21 also acquires the parking space coordinates stopped by the photographed vehicle by photographing the coordinates. The toll collector device 21 then transmits the license plate image 221 and the parking space coordinates stopped by the photographed vehicle to the server 11 via the wireless network. In addition, the toll collector device 21 can also transmit the parking ticket billing record, the next billing time, the estimated parking time, the departure time, and the unused parking grid number to the server according to the preset setting. .

After receiving the data transmitted by the toll collector device 21, the server 11 compares the parking space coordinates in the parking space data 13 with the parking space coordinates stopped by the photographed vehicle, and utilizes image recognition. The technique is to identify the license plate number of the license plate image 221, and transmit the identified license plate number to the toll collector device 21 for confirmation by the toll collector. In addition, the status of the parking space corresponding to the corresponding parking space coordinates is updated to be used, and the received data is integrated to achieve the effect of managing each parking space.

When the vehicle leaves the parking space, the toll collector only needs to take the parking space once again. Since the captured image does not have a license plate, there is no license plate number. In the absence of the license plate number, the toll collector device 21 can only Transmitting the image, the photographing coordinates, and the parking grid coordinates to the server 11. After receiving the data, the server 11 can determine that the parking grid is no longer in use by the comparison coordinate, and the parking is stopped. The status of the parking space updated in the cell library 12 is unused.

In addition, if another vehicle is parked after the vehicle leaves, a different license plate number will occur when the vehicle license plate number is obtained. This means that the previous vehicle has left and the current car is parked there. In the parking space, the license plate number of the current car is used as the billing object. The data transmitted to the server contains the coordinates of the parking space and the license plate number, and the server can judge that the previous vehicle has not stopped at the parking space, and the new parking vehicle is used for charging. And maintaining the state that the parking space is in use.

Since each of the parking spaces has its corresponding road name, each parking space can be used with the road name to form a parking space information sufficient for the general person to know a certain road section. In actual implementation, the coordinates of each road may also be input into the parking space database 12 for combination with the plurality of parking spaces 13 .

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

As shown in FIG. 5, it should be added that the information contained in the parking space database 12 of the server 11 can further cooperate with today's smart phones to provide graphical information to make it easier for users to understand parking. Information. For example, the system of the present invention may further include a consumer software 31 that is installed on a consumer handset 32 (as in the case of a smart phone) that executes the consumer. The software 31 accesses the parking space database 12 of the server 11 via the wireless network, and displays the information contained in the parking space database 12 on the consumer handheld device 32.

As shown in Figure 6, when displayed, it is the easiest to understand by means of a map, and the displayed content must at least show the road and its name, the parking space next to the road, and each The state of use of the parking space. What is shown in Figure 6 is the road and the parking space P next to the road. The hollow parking space P is unused, and the solid parking space P is in use (ie, occupied by the vehicle). The display mode allows the user to easily understand the use of the parking space P on this road segment.

In summary, the present invention can not only manage the use status of each parking space, but also confirm the coordinate position and the road segment corresponding to each parking space. In addition, the present invention can also allow a general user to install the consumer software 31 to access the server. The parking space database 12 in 11 displays the parking space information on the consumer handheld device 32 in the form of a map so that the general consumer can easily understand.
