As an important link in the construction and connection of the Taizhou Power Plant of the National Energy Group, 5G has achieved full coverage of the 5G network in the entire power plant area through the joint construction and sharing of 5G by telecom operators. The 5G network is used to transmit the positioning data collected by each switch to the user center, and the internal data separation is realized through edge computing equipment to ensure data security and effectively reduce network delay; at the same time, the integrated construction of 5G + UWB positioning accuracy dual network greatly reduces aggregation. The complexity of line design provides a network channel for multi-device connection, saving a lot of investment and maintenance costs for optical fiber lines and equipment.

According to the construction goal of the national energy power plant, the high-precision positioning management system based on UWB module positioning technology provides powerful data support for the information management and intelligent control of the power plant.

Personnel intelligent management

Based on the UWB module positioning technology, it can accurately locate the location of the on-site personnel in the power plant, and query the activity trajectory and basic information of the on-site personnel on the 3D map in real time; support personnel attendance, operator statistics, on-the-job status query, inspection control, etc.

area operation control

Power plant areas are divided by virtual electronic fences, such as operator count, high-risk operation areas, and area access permission settings. Integrate with the two-ticket system, connect the access control in the area, and automatically authorize and reclaim permissions according to the operation start time and end time. At the same time, regional risk information can be pushed to relevant operators for risk pre-control.

Security early warning control

Electronic fences are set up in high-risk and accident-prone areas, including rapid evacuation, intrusion alarm, overtime, etc. Once the on-site personnel violate the regulations, a remote alarm prompt will be issued; in an emergency, the on-site personnel can also send an emergency alarm signal; combined with the video surveillance system, it supports the rapid call of the camera.

The National Energy Power Plant Project has created a new demonstration application of 5G+UWB positioning accuracy smart power plant construction, witnessed the rapid development of the 5G+UWB industry, and will create a new blueprint in the field of location services with industry partners.
