[0028] Figure 1 The schematic diagram of the structure of a roadside terminal device provided by the embodiment of the utility model is applicable to the case of realizing a roadside terminal device with high reliability and low cost. Figure 1 As shown, a main control unit 100, a data processing unit 200 and a data communication unit 300 are integrated on the main board of the roadside terminal device 10; the data processing unit 200 includes a first data input terminal and a first data output terminal, the first data input terminal is used to receive traffic sensing data to be processed, and the first data output terminal is used to output the traffic sensing data processed by the data processing unit 200; the main control unit 100 includes a second data input terminal and a second data output terminal, the second data input terminal is connected to the first data output terminal, and the second data output terminal is connected to the data communication unit 300.
[0029] In this embodiment, the main control unit 100 can serve as the core unit of the roadside terminal device 10, for example, it can be a processor, which can be used to broadcast the processed traffic sensing data to the device that can receive the processed traffic sensing data (such as a vehicle, a cloud center platform, etc.) through the data communication unit 300, and can also be used to broadcast other traffic data that is different from the traffic sensing data to the device that can receive the traffic data (such as a vehicle, a cloud center platform, etc.). The data processing unit 200 can be understood as a unit for processing the traffic sensing data to be processed, and can have the function of MEC. The data communication unit 300 can be used to broadcast the processed traffic sensing data to the device that can receive the processed traffic sensing data (such as a vehicle, a cloud center platform, etc.), and can also be used to broadcast other traffic data that is different from the traffic sensing data to the device that can receive the traffic data (such as a vehicle, a cloud center platform, etc.).
[0030] Traffic perception data can be understood as data within a certain range collected by roadside fixed equipment. Traffic perception data may include, for example, at least one of the speed of vehicles, the position of vehicles, the driving route of vehicles, and the position of pedestrians within the range that can be collected by roadside fixed equipment. Among them, roadside fixed equipment can be understood as equipment installed on the roadside that can collect traffic perception data, for example, it may include cameras and / or radars. Traffic perception data to be processed can be understood as unprocessed traffic perception data that needs to be processed. Processed traffic perception data can be understood as traffic perception data processed by the data processing unit 200. The processed traffic perception data can be better managed and used by the main control unit 100 and the data communication unit 300. The processed traffic perception data may be, for example, traffic perception structured data; traffic perception structured data can be understood as traffic perception data organized according to fixed formats and rules.
[0031] The first data input terminal can be used to receive the traffic sensing data to be processed for the data processing unit 200. The first data input terminal can be connected to the main control unit 100, and can be used to receive the traffic sensing data to be processed collected by the main control unit 100. The first data input terminal can also be connected to other devices or units (such as data collection units) that collect traffic sensing data; the first data output terminal can be used to output the traffic sensing data processed by the data processing unit 200. The first data output terminal can be directly connected to the second data input terminal of the main control unit 100, or can be connected to the second data input terminal via other devices or units (such as data exchange units).

The data processing unit 200 transmits the processed traffic sensing data to the main control unit 100 through the second data input terminal of the main control unit 100 via the first data output terminal of the data processing unit 200. The main control unit 100 transmits the received processed traffic sensing data to the main control unit 100 through the second data output terminal of the main control unit 100. The perception data is transmitted to the data communication unit 300, and the data communication unit 300 then transmits the received processed traffic perception data to a device that can receive traffic perception data. The above constitutes a roadside terminal device 10, which realizes the functions of the two devices RSU and MEC in the prior art with one device of the roadside terminal device 10, that is, the user only needs to install one device in actual deployment, which can reduce the workload of actual deployment and avoid the compatibility problem of the two devices. It can not only reduce the difficulty and cost of on-site construction, but also improve the reliability of the roadside terminal device 10, which helps to realize efficient and accurate data transmission, and thus improve the user experience. In other words, the roadside terminal device 10 is a device that is easy to install, easy to maintain and highly reliable.
[0033] Exemplarily, the main control unit 100 integrated on the main board of the roadside terminal device 10 may be a central processing unit (CPU), and the data processing unit 200 integrated on the main board may be an artificial intelligence (AI) computing unit. The AI computing unit receives the traffic perception data to be processed, such as the traffic perception data to be processed is collected by the camera and the radar. The AI computing unit may process the traffic perception data to be processed using the existing processing method to obtain the processed traffic perception data. For example, the AI computing unit may decode and extract features of the traffic perception data collected by the camera to obtain the camera perception data, may extract features of the traffic perception data collected by the radar to obtain the radar perception data, and then may perform feature fusion processing on the camera perception data and the radar perception data, and generate structured data from the traffic perception data after the feature fusion processing, that is, the processed traffic perception data is obtained. After obtaining the processed traffic perception data, the AI computing unit may transmit the processed traffic perception data to the CPU. The CPU may broadcast the processed traffic perception data to the vehicle-mounted device and / or the cloud center platform via the data communication unit 300.
[0034] It should be noted that the data communication unit 300 can also output data to the main control unit 100 .
