Wuhu Shipyard, formerly known as Fujiheng Machinery Factory founded in 1900, has a history of 121 years. Mao Zedong, Zhu De, Li Peng and other generations of state leaders have inspected the company. With its long shipbuilding history and rich shipbuilding experience, the company has set 34 No. 1 in China's shipbuilding industry, making a significant contribution to China's shipbuilding history. The new plant area has built two 80000 ton shipways (240mX40m), 850m outfitting docks, hull joint workshop, sectional assembly and welding workshop, pipe processing workshop, fully enclosed painting workshop and other complete shipbuilding facilities, and is equipped with domestic advanced ultra thick plasma cutting machines, large three-star rollers, 450 ton gantry cranes, 150 ton cranes and various advanced shipbuilding equipment, which is the largest in Anhui Province State owned shipbuilding enterprises with the highest degree of modernization.
Customer Challenges
Wuhu Shipyard covers a very large area, with large and scattered workshops, workshops, and operation rooms. Vehicles, equipment, and personnel are dense in some plants, making it difficult to count the number of regional staff; The construction team has a complex structure and a large mobility of personnel, which poses a great challenge to personnel attendance statistics, personnel safety management and equipment asset management.
Solution
The first batch of sites to be installed in Wuhu Shipyard are tooling workshops with an area of 20000 square meters. A total of 150 standard inventory base stations have been laid, with the highest site of 25 meters. In addition, 20 remote inventory base stations and 2000 helmet type personnel tags have been equipped.
Considering that the safety helmet is the only production material that the workers carry with them and are forced to carry at all times when they work in the factory, the label is placed on each safety helmet. In combination with the two types of base stations on site, personnel can be positioned in and out of the area, and their movement track and retention time can be clearly seen. It greatly improves the efficiency of personnel management.
Outstanding results
1. Personnel position management: The BTS captures label information at a radius of about 50M from the installation location, and the system judges that the ID bound personnel are active in the area near the BTS; After the ID is captured by other base stations as the personnel move, the system can judge that the personnel move to the vicinity of the base station with high received signal strength according to the signal strength, so as to realize the location in the area.
2. Personnel attendance management: provide confirmation of personnel entering/leaving the factory according to personnel location information, and provide customized reports such as base station personnel information query statistics, operation duration statistics, etc.
3. Personnel safety management: the system can draw dangerous and prohibited areas according to the site requirements, and provide statistics and alarms of personnel staying in dangerous and prohibited areas (judge the last position information of personnel according to time).
4. Personnel movement track: At the same time, it can provide a query to judge the movement track of personnel relying on the base station through the reception of the base station.
5. Remote visual management: the system can operate and control after logging in to the internal network, check the thermal map of the personnel location area, and realize remote visual management.
6. High system security: ECDSA digital signature and ECDH key agreement technology that are the same as the blockchain are used. The non-standard protocol is adopted, which makes it impossible for non Aviva interconnection equipment to access and obtain information.
