Description

Technical Field

[0001] The utility model relates to the technical field of traffic supervision, and in particular to a non-road mobile machinery supervision system. Background Art

[0002] Non-road mobile machinery is of various types and widely used. Compared with motor vehicles, it has problems such as unclear basic data, relatively backward pollution control level, and large pollutant emissions. Therefore, it is necessary to regulate non-road mobile machinery.

[0003] The current supervision method is generally to designate a low-emission zone for non-road mobile machinery within a certain geographical range in the central urban area, and prohibit the use of all non-road mobile machinery that meets the National II emission standards and below in the low-emission zone. At the same time, relevant personnel are required to conduct on-site inspections at each construction site to check whether each non-road mobile machinery meets the emission standard requirements. However, this supervision method requires a lot of human resources and cannot be implemented when human resources are insufficient.

[0004] In order to solve the problem caused by the existing supervision method relying on a lot of human resources, one solution currently proposed is to install a positioning device on each non-road mobile machinery. However, the positioning device itself is expensive, which leads to high supervision costs and is not conducive to popularization.

[0005] Therefore, there is an urgent need to provide a regulatory system with relatively low total regulatory costs. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide a non-road mobile machinery supervision system to reduce the total supervision cost of the non-road mobile machinery and improve the integration of the entire system to facilitate installation and use.

[0007] In order to achieve the above purpose, the technical solution adopted by the embodiment of the utility model is as follows:

[0008] The embodiment of the utility model provides a non-road mobile machinery supervision system, including an image acquisition device, an RFID identifier and a main control device; the image acquisition device and the RFID identifier are respectively connected to the main control device for communication;

[0009] The image acquisition device is used to acquire the license plate image of the non-road mobile machinery at the entrance of the target monitoring location, and transmit the license plate image to the main control device;

[0010] The RFID identifier is used to identify the license plate RFID tag of the non-road mobile machinery at the passage, obtain the license plate information, and transmit the license plate information to the main control device;

[0011] The main control device is used to send the received license plate image and license plate information to the supervision center;

[0012] There are two image acquisition devices, and the monitoring directions of the two image acquisition devices are opposite. The monitoring direction of one of the image acquisition devices is toward the passage, and the monitoring range of the two image acquisition devices and the identification range of the RFID identifier jointly cover the area where the passage is located.

[0013] The utility model forms a supervision system by using two image acquisition devices, an RFID identifier and a main control device, and installs the supervision system at the entrance of the target monitoring location. For example, a supervision system is installed at the entrance of the construction site, and a supervision system can also be installed at the exit of the construction site. The license plate image and license plate information are collected through such a supervision system, and the main control device sends them to the supervision center. In this way, the supervision center can know whether the vehicle has an environmentally friendly license plate based on the license plate image and license plate information, and can find out whether there is a high-emission non-road mobile machinery entering the low-emission area, so as to achieve supervision. Therefore, the non-road mobile machinery supervision system provided by the utility model can achieve the following beneficial technical effects:

[0014] First, compared with the supervision scheme of installing a positioning device on each non-road mobile machinery, as long as a supervision system for non-road mobile machinery is installed in the low-emission zone, all non-road mobile machinery entering the low-emission zone can be detected, which significantly reduces the cost of infrastructure supervision. In addition, there is no need for supervisors to conduct on-site supervision, which greatly reduces the cost of administrative supervision.

[0015] Secondly, by using image acquisition equipment and RFID identifiers to obtain license plate information respectively, it is possible to prevent the image acquisition equipment from being unable to capture or unable to clearly capture license plate information due to certain circumstances, thereby ensuring the stability of license plate information acquisition. In addition, the license plate information of the same non-road mobile machinery obtained by different devices can be combined to determine whether the license plate is fake, laying a solid foundation for regulatory reliability;

[0016] Thirdly, by utilizing two image acquisition devices with opposite monitoring directions, since the monitoring direction of one of the image acquisition devices is toward the entrance, the license plate image can be acquired by one of the image acquisition devices before the non-road mobile machinery enters, and the license plate image can be acquired by the other image acquisition device after the non-road mobile machinery enters. This is beneficial to increasing the acquisition viewing angle of the license plate image, thereby preventing missed recognition due to the unstable position of the license plate.

[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, preferred embodiments are given below and described in detail with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0026] It should be noted that like reference numerals and letters denote similar items in the following drawings, and thus, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0027] In the description of the present utility model, it should be noted that if terms such as orientation are mentioned, for example, "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc., the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the corresponding drawings, or the orientation or position relationship in which the utility model product is usually placed when in use. It is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0028] In addition, terms such as "horizontal" and "vertical" do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" may simply mean that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0029] In the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", "connection", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be directly connected, or connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] In order to solve the technical problem of high supervision cost of non-road mobile machinery in related technologies, the embodiment of the utility model provides a non-road mobile machinery supervision system, which forms a supervision system by using two image acquisition devices, RFID identifiers and main control devices, and installs this supervision system at the entrance of the target monitoring location. For example, a supervision system is installed at the entrance of the construction site, and a supervision system can also be installed at the exit of the construction site. The license plate image and license plate information are collected through such a supervision system, and sent to the supervision center by the main control device. In this way, the supervision center can know whether the vehicle has an environmentally friendly license plate based on the license plate image and license plate information, and can find out whether there are high-emission non-road mobile machinery entering the low-emission area, so as to achieve supervision. The following beneficial technical effects are achieved:

[0031] First, compared with the supervision scheme of installing a positioning device on each non-road mobile machinery, as long as a supervision system for non-road mobile machinery is installed in the low-emission zone, all non-road mobile machinery entering the low-emission zone can be detected, which significantly reduces the cost of infrastructure supervision. In addition, there is no need for supervisors to conduct on-site supervision, which greatly reduces the cost of administrative supervision.

[0032] Secondly, by using image acquisition equipment and RFID identifiers to obtain license plate information respectively, it is possible to prevent the image acquisition equipment from being unable to capture or unable to clearly capture license plate information due to certain circumstances, thereby ensuring the stability of license plate information acquisition. In addition, the license plate information of the same non-road mobile machinery obtained by different devices can be combined to determine whether the license plate is fake, laying a solid foundation for regulatory reliability;

[0033] Thirdly, by utilizing two image acquisition devices with opposite monitoring directions, since the monitoring direction of one of the image acquisition devices is toward the entrance, the license plate image can be acquired by one of the image acquisition devices before the non-road mobile machinery enters, and the license plate image can be acquired by the other image acquisition device after the non-road mobile machinery enters. This is beneficial to increasing the acquisition viewing angle of the license plate image, thereby preventing missed recognition due to the unstable position of the license plate.

[0034] For details, please refer to Figure 1 , Figure 1 It is a hardware framework diagram of a non-road mobile machinery supervision system provided by an embodiment of the utility model; the non-road mobile machinery supervision system 100 includes an image acquisition device, an RFID identifier 130 and a main control device 140; the image acquisition device and the RFID identifier 130 are respectively communicated with the main control device 140.

[0035] The image acquisition device is used to acquire the license plate image of the non-road mobile machinery at the entrance of the target monitoring location, and transmit the license plate image to the main control device 140 .

[0036] The RFID identifier 130 is used to identify the license plate RFID tag of the non-road mobile machinery at the passage, obtain the license plate information, and transmit the license plate information to the main control device 140.

[0037] The main control device 140 is used to send the received license plate image and license plate information to the supervision center.

[0038] There are two image acquisition devices, and the monitoring directions of the two image acquisition devices (110 and 120) are opposite. The monitoring direction of one of the image acquisition devices is toward the passage, and the monitoring ranges of the two image acquisition devices (110 and 120) and the identification range of the RFID identifier 130 jointly cover the area where the passage is located.

[0039] The working principle of the non-road mobile machinery supervision system provided by the embodiment of the utility model is described below in combination with actual application scenarios:

[0040] See also Figure 2 , Figure 2 This is a top view of an application scenario of a non-road mobile machinery monitoring system provided by an embodiment of the utility model. Before using the non-road mobile machinery monitoring system provided by an embodiment of the utility model, you can first Figure 2 In the manner shown, the two image acquisition devices (110 and 120) and the RFID identifier 130 of the road mobile machinery monitoring system are installed at the entrance of the target location to be monitored, and the entrance can be an entrance or an exit. Figure 2 As shown in the figure, when the target location is a construction site, the non-road mobile machinery monitoring system provided by the embodiment of the utility model can be installed at the entrance of the construction site. Figure 2 The main control device 140 not shown in the figure can be installed in the control center of the construction site, or in the security room at the entrance of the construction site, or on the RFID identifier 130 and any one of the two image acquisition devices (110 and 120), which is not limited in this embodiment.

[0041] After the non-road mobile machinery supervision system is installed, it can be started to operate. During the operation, each image acquisition device and the RFID identifier 130 can collect license plate information in real time, or only collect license plate information when a non-road mobile machinery that needs to enter the construction site entrance is detected.

[0042] When the non-road mobile machinery just runs to the factory entrance or a certain position in front, it will enter the monitoring range of the image acquisition device 110 and the identification range of the RFID identifier 130. At this time, the image acquisition device 110 can obtain the license plate image at the head of the non-road mobile machinery and transmit it to the main control device 140. Similarly, the RFID identifier 130 can read the license plate information of the license plate RFID tag and transmit the license plate information to the main control device 140. Subsequently, when the non-road mobile machinery continues to move forward into the monitoring range of the image acquisition device 120, the image acquisition device 120 will obtain the license plate image at the rear of the non-road mobile machinery and transmit it to the main control device 140. It can be seen that the three license plate information acquisition devices cooperate with each other to well cover the area where the pass is located, effectively reducing the visual blind spot.

[0043] After receiving the license plate images sent by the image acquisition devices 110 and 120 and the license plate information recognized by the RFID identifier 130, the main control device 140 sends the license plate images and license plate information to the remote supervision center A. Figure 3 As shown, Figure 3 This is a communication scenario diagram of a non-road mobile machinery supervision system provided by an embodiment of the utility model. After receiving the license plate image and license plate information, the supervision center A can show them to the supervisor, who will judge whether the license plate number of the non-road mobile machinery is an environmental protection number, whether it is illegal, whether there is license plate fraud, etc., based on the license plate image and license plate information. This achieves the purpose of supervision.

[0044] In the above, it should be noted that the supervision center A can be a supervision platform in the supervision department, or it can be a part of the non-road mobile machinery supervision system provided by the embodiment of the utility model, and the embodiment of the utility model does not limit this. In addition, if there is a need to improve the intelligence of the supervision center A, that is, there is no need for supervisors to make the above judgments, corresponding image recognition functions, information judgment functions and violation judgment functions can be added to the supervision center A. The implementation schemes of these functions can all be referred to the relevant technologies, and will not be repeated here.

[0045] It is worth noting that the core of the utility model is to propose a hardware framework and mechanical structure implementation plan for a non-road mobile machinery supervision system. It does not involve algorithmic steps such as license plate image recognition, information judgment and violation judgment, nor does it improve these algorithmic steps.

[0046] In some embodiments, in order to ensure that the monitoring range of the two image acquisition devices (110 and 120) and the identification range of the RFID identifier 130 cover the passage, the embodiment of the utility model also provides a technical solution with a better relative position relationship between the image acquisition device and the RFID identifier 130, that is, the two image acquisition devices (110 and 120) are used to be installed on the inner side of the passage and are respectively arranged on both sides of the passage of the passage; the RFID identifier 130 is used to be installed above the passage and is located between the two image acquisition devices (110 and 120). The description of the above position relationship can be combined with Figure 2 Please understand and I will not elaborate on it here.

[0047] Although the above-mentioned embodiments can ensure the coverage of the passage by the monitoring range of the two image acquisition devices (110 and 120) and the identification range of the RFID identifier 130, since each device in the non-road mobile machinery monitoring system is a relatively independent component, in order to facilitate transportation and manufacturing, the devices in the monitoring system will not be directly assembled. Therefore, in the application stage, the user needs to assemble each device in the monitoring system according to the corresponding instructions and install it at the passage. This increases the installation difficulty for the user and is not convenient for quick installation, thereby consuming a lot of time and is not conducive to improving the use efficiency of the monitoring system. In view of this, in some embodiments, the embodiments of the utility model also provide a quick installation structure that can achieve the monitoring range of the two image acquisition devices (110 and 120) and the RFID identifier 130, that is, please refer to Figure 4 , Figure 4 It is a structural schematic diagram of a non-road mobile machinery supervision system provided in an embodiment of the utility model. The non-road mobile machinery supervision system provided in an embodiment of the utility model may also include a first installation auxiliary bracket 410, a second installation auxiliary bracket 420 and a third installation auxiliary bracket 430.

[0048] The first mounting auxiliary bracket 410 and the second mounting auxiliary bracket 420 are respectively disposed on the two image acquisition devices (110 and 120), and the first mounting auxiliary bracket 410 and the second mounting auxiliary bracket 420 are both provided with a connecting seat.

[0049] The third auxiliary mounting bracket 430 is disposed on the RFID identifier 130 , and a first connecting seat and a second connecting seat are respectively disposed on two opposite sides of the third auxiliary mounting bracket.

[0050] The first connection seat and the second connection seat of the third auxiliary mounting bracket 430 are used to be connected to the connection seats in the first auxiliary mounting bracket 410 and the second auxiliary mounting bracket 420 through auxiliary rods respectively.

[0051] Among them, each installation auxiliary bracket can be integrally formed with its corresponding device, or can be separately set. In the case of separate setting, each installation auxiliary bracket and its corresponding device's outer shell can be configured with mutually matching positioning holes and positioning columns. The positioning holes and positioning columns can not only make the installation auxiliary bracket match the corresponding device shell, but also make the installation auxiliary bracket accurately installed on the corresponding device shell in a set orientation, so as to ensure the accuracy of installation and the accuracy of subsequent connection through the auxiliary rod.

[0052] Therefore, by adding auxiliary installation brackets and auxiliary rods, since the connection method between the auxiliary installation brackets and the auxiliary rods is fixed, in order to enable the auxiliary rods to be smoothly connected between the two auxiliary installation brackets, these auxiliary installation brackets must be located in a fixed position, thereby limiting the relative position relationship of each device on the auxiliary installation bracket, making it convenient for users to install and use the supervision system and saving installation time. It can be seen that the non-road mobile machinery supervision system provided by the utility model also has good practicality.

[0053] In addition, in order to meet the user's demand for adjusting the monitoring range of the image acquisition device according to different scenarios, in some embodiments, each image acquisition device can be configured with a pan / tilt head.

[0054] Based on any of the above-mentioned embodiments with a quick installation structure, after each image acquisition device and RFID identifier 130 are installed, in order to avoid the auxiliary rod occupying the construction site space or blocking the image acquisition device and RFID identifier 130, in some embodiments, both ends of any auxiliary rod are connected to the connection seat through a detachable connection structure. The detachable connection structure can adopt any one of the related technologies, which will not be described in detail here. Therefore, by setting the connection structure between the auxiliary rod and the connection seat to be detachable, the auxiliary rod can be easily disassembled to avoid occupying the construction site space and blocking the image acquisition device and RFID identifier 130.

[0055] Based on the previous embodiment, in order to further facilitate the disassembly of any auxiliary rod, in some embodiments, any auxiliary rod can be a telescopic connecting rod. In this way, when the auxiliary rod needs to be disassembled, the auxiliary rod can be retracted after the auxiliary rod and the connecting seat are unlocked, so as to achieve quick separation from the connecting seat. At this time, the removal of the auxiliary rod will not be hindered by the connecting seat, which makes the disassembly of the auxiliary rod more convenient.

[0056] In some embodiments, to ensure the effective identification range of the RFID identifier 130, the RFID identifier 130 has an operating frequency of 902-908 MHz, an output power of 0-30 dBm, and an identification distance of 0-12 m. Thus, by using the RFID identifier 130 of the above specifications, it can be ensured that the RFID identifier 130 can reliably read the license plate information.

[0057] In some embodiments, in order to improve the communication stability of the main control device 140 and meet different communication requirements, the main control device 140 includes a processor and a communication unit; the communication unit includes an Ethernet communication unit, a WIFI module and a cellular network module.

[0058] In some embodiments, in order to improve the supervision and effectiveness of illegal non-road mobile machinery, the non-road mobile machinery supervision system provided by the embodiment of the utility model may also include an alarm connected to the main control device 140; the main control device 140 is also used to receive the alarm information sent by the supervision center, and control the alarm to sound an alarm according to the alarm information. Therefore, by adding an alarm, relevant personnel at the current site can be informed of the existence of illegal non-road mobile machinery in a timely manner, and relevant management measures can be taken in a timely manner.

[0059] Based on the previous embodiment, in order to strengthen supervision, further improve the effectiveness of supervision and prevent illegal non-road mobile machinery from entering the relevant area, in some embodiments, the non-road mobile machinery supervision system provided by the embodiment of the utility model may also include a gate installed at the passage; the main control device 140 is also used to control the gate to be in a closed state when receiving the alarm information. The gate can be a gate in the related technology, and its mechanical structure is not described here.

[0060] Based on any embodiment of the non-road mobile machinery supervision system having an alarm, in order to further improve the effectiveness of supervision, in some embodiments, the main control device 140 is also used to send an alarm message to the associated user terminal when receiving the alarm message.

[0061] It is worth noting that the technical features or technical solutions in any of the above embodiments of the present invention can be combined or combined with each other as long as there is no contradiction in the combination or combination.

[0062] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
