Yunnan Baoshan portable integrated high-definition image monitoring device application

Background: Baoshan is located in the southwestern part of Yunnan Province. The terrain is mostly high mountains and mountains. The inspection is difficult and takes a long time. The inspection work is relatively difficult. A large number of transmission lines are distributed in mountainous areas and inaccessible areas, and manual inspections take place once. It takes a lot of time to reach the scene. The traffic is inconvenient, the vehicle cannot reach the designated tower, and it is necessary to walk. Therefore, it takes a lot of time to patrol a base tower. Introduce technical means to assist line inspection.

Application effect: The large-scale mechanical identification accuracy is improved to over 90% through line on-site simulation, the alarm accuracy rate is 100%, and the overall power consumption of the device is 2W (sleeping 0.5w). Video resolution 720P. Transmission fault tolerance efficiency is enhanced to level 1. Through dual-channel multi-wheel test, the communication traffic of the high-precision picture is reduced by 25% compared with the traditional device after the patch is modified. After using the chip-type communication card, the communication stability is lower than that of the non-slice type. The efficiency of fault tolerance has been greatly improved. Often online testing, the discharge process of the 20.8AH lithium iron phosphate battery ensures that the device can be used for up to 25 days in the absence of light. With solar energy, it can achieve an on-line MTBF ≥ 25,000 hours.

Social and economic benefits: Through the application of project results, the stand-alone cost is reduced to less than 10,000 yuan. The monthly running cost (communication fee) is reduced to 10 yuan / month. By increasing the training cost and software usage efficiency by accessing the WeChat client, the accessibility is increased to some extent. The single deployment has reduced the one-time capital investment by 30,000 yuan. The timeliness of inspection is several times higher than that of labor. In areas with inconvenient transportation, it may take 3-4 hours for the labor to arrive at the scene to conduct inspections.
