Description

Technical Field

[0001] This invention relates to the field of data acquisition equipment technology, and in particular to a real-time automatic data acquisition system for highways. Background Technology

[0002] To facilitate highway traffic management departments in obtaining real-time information about highway surfaces (so that they can deploy controls accordingly), to enable them to quickly grasp traffic accidents and road conditions, and to respond promptly and take appropriate emergency measures, thus gaining valuable time for accident rescue and troubleshooting, and also to achieve efficient evidence collection of illegal use of emergency lanes on highways, highways are generally equipped with real-time automatic data collection systems for collecting images and real-time environmental data.

[0003] In existing technologies, surveillance cameras and various sensors are generally installed on highway gantry frames and road sign frames, and highway patrol vehicles are used to collect data. In order to ensure passability and avoid affecting traffic, highway patrol vehicles often use highway guardrails as guide rails for movement. Existing high-speed patrol vehicles suffer from the following drawbacks due to their structural limitations: Because highway guardrails come in various specifications (with differences in model, manufacturer, and production batch), a single-specification highway patrol vehicle is difficult to adapt to different specifications of highway guardrails. Manufacturing patrol vehicles specifically for each specification of guardrail or modifying the guardrails is costly, cumbersome, and inconvenient.

[0004] Therefore, there is a need for a real-time automatic data acquisition system for highways that can be adapted to different shapes, is highly applicable, and does not require modification of highway guardrails during use. Summary of the Invention

[0031] The track-traveling assembly is used in conjunction with the obstacle avoidance bar assembly to drive the base frame 100 and its components along the highway guardrail, including the top wheel assembly 410 and the side wheel assembly 420. The top wheel assembly 410 is positioned at the bottom of the top plate 110. There are multiple of them, arranged in a row, and they always contact the top of the guard plate 003 when the patrol vehicle is moving.

[0032] If the connecting rod 411 is an electric telescopic rod, the patrol vehicle can adjust its shape while driving to adapt to different specifications of highway guardrails.

[0033] The obstacle avoidance rod assembly includes two or more basic rotating rods 500; one end of the basic rotating rod 500 is rotatably connected to the edge of the top plate 110 away from the side plate 120 or rotatably connected to the edge of the bottom plate 130 away from the side plate 120, and rotates in a controlled manner to abut the surface of the guard plate 003 near the column 001 in a timely manner, thereby restricting the basic frame 100 and its components from slipping off the guard plate 003; When the patrol vehicle travels along the guardrail 003, all the basic rotating rods 500 are arranged in a row and are in a vertical or nearly vertical state when they are not close to obstacles (such as pillars 001). The basic rotating rod 500 includes a basic rotating column 510, a support frame 520, and a stop wheel assembly 530; The basic rotating column 510 is a horizontally placed rigid column, which is rotatably connected to the edge of the top plate 110 away from the side plate 120 or rotatably connected to the edge of the bottom plate 130 away from the side plate 120, and rotates under the coordinated control of the power component and the control unit.

Patrol vehicles traveling along the highway guardrails are also connected to the highway traffic management department's management system via their own communication modules, transmitting real-time images and environmental information. This allows the highway traffic management department to have real-time access to highway road information and to deploy appropriate controls based on this information, enabling timely emergency measures to be taken. This buys valuable time for accident rescue and troubleshooting, and also allows for efficient evidence collection of violations of emergency lane usage on highways, thereby effectively curbing highway traffic violations.

[0036] Furthermore, a stabilizing component is positioned between the data acquisition unit 300 and the base frame 100; the stabilizing component is existing technology and will not be described in detail here.

[0037] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages: This invention solves the technical problem of poor applicability of patrol vehicles used in existing technologies for collecting highway data, and achieves the technical effect of an automatic real-time data collection system for highways that can be adjusted as needed, has strong applicability, and does not require modification of highway guardrails during use.
