Recently, OpenHarmony has made a new breakthrough in the transportation industry: the smart tunnel solution based on OpenHarmony has been successfully commercialized in Jiangxi Expressway Yingpan Tunnel and Meiling Tunnel, providing an excellent sample for the intelligent transformation of highway tunnels nationwide and pushing forward the innovation of smart tunnels in the industry.

With the gradual improvement of highway network in China, tunnel is regarded as the throat of highway, and its operation level will directly affect the safety and traffic efficiency of highway, which is very important to the operation safety management of tunnel. At the same time, the scene is becoming more and more complex, and the requirements for tunnel operation in active discovery, rapid response, emergency disposal, efficient operation and maintenance in traffic incidents are also higher and higher. However, at present, it has a large number of traditional tunnel electromechanical systems, and there are still many pain points in daily operation and maintenance and management, such as difficult to find traffic incidents, slow emergency coordination response, unknown electromechanical status and low equipment operation and maintenance efficiency.

Starting from 2021, Jiangxi Communications and Investment Group, together with Huawei and many partners, jointly built a "cloud-edge-end" collaborative intelligent tunnel solution based on OpenHarmony, helping the tunnel to evolve towards the goals of safe operation management, efficient operation and maintenance and green and low carbon. The successful Jiangxi Expressway Yingpan Tunnel and Meiling Tunnel are important achievements of cooperation between the two sides. After the intelligent transformation of OpenHarmony, the efficiency of the tunnel in traffic incident monitoring and disposal and electromechanical equipment operation and maintenance has been greatly improved, realizing safe and efficient operation and maintenance and independent innovation.

In the monitoring and disposal of traffic incidents, due to the closed protocol of electromechanical equipment in traditional tunnel network and the difficulty of data interconnection, traditional emergency disposal needs manual serial operation in multiple systems, and it is difficult to quickly find target equipment, and there are hundreds of kinds of disposal plans, which are low in efficiency and easy to make errors, which affects the efficiency of emergency disposal. Therefore, when a tunnel traffic incident is discovered, the precise and efficient linkage control of electromechanical equipment becomes the key factor for the rapid occurrence of the incident. Now, the intelligent tunnel solution based on OpenHarmony + Internet of Things technology can realize unified state acquisition and linkage control of various devices in the tunnel. At the same time, the system also preset 8 kinds of abnormal event handling plan library in advance. After the event is found, the system will automatically match the plan according to the event type and incident position, and the staff can start the "one-key" linkage control after confirmation, thus avoiding the occurrence of secondary accidents to the greatest extent and improving the processing efficiency several times. Taking the old Yingpan Tunnel as an example, the Incident Response Service has been improved from 5-10 minutes to 1-2 minutes now.

In terms of operation and maintenance, the traditional tunnel intelligent means are insufficient. After adopting OpenHarmony technology, all traditional electromechanical equipment in tunnels are transformed into intelligent terminals, which can collect equipment information independently, report in real time, and identify equipment faults through multi-source data analysis. Now inspectors can automatically connect OpenHarmony electromechanical equipment, read the operation status of the equipment, perform various operation operations locally, and feed back the operation results by holding the intelligent inspection terminal "touch touch", which greatly improves the equipment fault location ability and overall operation and maintenance efficiency.

According to the relevant person in charge of Jiangxi Communications and Investment Group, the smart tunnel solution based on OpenHarmony has been officially put into production for more than 6 months, and more valuable operation data will be obtained through pilot projects to continuously optimize the scheme. In the future, we will jointly establish smart tunnel standards with excellent enterprises in the industry, push them to the whole country, truly improve the experience of drivers and passengers through digital means, and serve the people's beautiful travel.

The intelligent tunnel solution based on OpenHarmony has been successfully commercialized in Jiangxi Expressway Yingpan Tunnel and Meiling Tunnel and achieved remarkable results, bringing great changes to tunnel operation and management. With the continuous innovation of technology and the continuous expansion of tunnel application scenarios, smart tunnel solutions equipped with OpenHarmony will play a greater role in the future and contribute to the intelligent upgrading of the transportation industry.
