Problems solved by technology
This method is too inefficient for collecting tunnel monitoring data. At the same time, during the collection process, traffic lanes need to be temporarily requisitioned, which will also affect the normal passage of vehicles in the tunnel. For inspection personnel, there are also major safety hazards

Embodiment Construction
[0033] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.
[0034] Any feature disclosed in this specification (including any appended claims, abstract), unless otherwise stated, may be replaced by alternative features that are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.
[0035] For WiFi-Aware, it has "peripheral awareness" capability, which can easily discover peripheral devices, applications and information, and discover applications before establishing a connection. WiFi-Direct focuses on the interconnection between devices, allowing devices to establish a connection without a wireless router, and has the characteristics of fast transmission speed and long communication distance.
[0036] Such as figure 1 As shown, the present em...

The invention discloses a tunnel flow monitoring system based on WiFi-Aware and WiFi-Direct and an operating method thereof. The tunnel flow monitoring system based on WiFi-Aware and WiFi-Direct comprises an inspection apparatus which supports WiFi-Aware and WiFi-Direct, and a plurality of monitoring apparatuses arranged separately in a plurality of tunnels and which support WiFi-Aware and WiFi-Direct; the monitoring apparatuses are used for acquiring monitoring data of the corresponding tunnels; the inspection apparatus discovers the multiple monitoring apparatuses through WiFi-Aware, and connects with the discovered monitoring apparatuses through WiFi-Direct so as to acquire monitoring data acquired by the monitoring apparatuses connected. The operating method comprises: when the inspection apparatus performs inspecting, transmitting out WiFi-Aware broadcast under a predetermined frequency; after a WiFi-Aware message transmitted by the monitoring apparatuses is received, connecting with the monitoring apparatus corresponding to the received WiFi-Aware message through WiFi-Direct so as to acquire monitoring data acquired by the monitoring apparatus. The tunnel flow monitoring system based on WiFi-Aware and WiFi-Direct and the operating method thereof have the advantages that personnel has no need to stay in the tunnels one by one to acquire monitoring data, monitoring data acquisition efficiency is improved, normal passage of vehicles in the tunnel is unaffected, and work is less dangerous for inspection personnel.
Description
technical field [0001] The invention relates to the field of tunnel monitoring, in particular to a tunnel flow monitoring system and operating method based on WiFi-Aware and WiFi-Direct. Background technique [0002] The continuous expansion and enrichment of the transportation network has brought great convenience to the emergence of people. In addition, the construction of tunnels and bridges has further shortened the road distance and improved the efficiency of people's travel. [0003] While the tunnel brings convenience to traffic, it also poses great safety hazards due to the limitation of maintenance frequency. At the same time, due to the particularity of the construction environment and the transportation function of carrying traffic, it is necessary to monitor its health. more real-time understanding. [0004] The traditional monitoring scheme for tunnels adopts the method of manual inspection, and the monitoring of the tunnel is realized by manually collecting d...
