Smart factory personnel positioning system solves factory personnel management problems

For manufacturing plants, "man-machine-material-method-environment" is the most critical factor. Today I will mainly share with you the management of personnel in manufacturing plants.

      Regarding where the people in the factory are and whether they have entered the dangerous area; whether there are critical incidents when working in the dangerous area; when an emergency occurs in the factory, whether rescue can be carried out quickly; whether the last location of each person can be accurately found; At the work station, whether you will go to the wrong station; statistics of daily working hours; time-based salary calculation, time-based beat efficiency optimization sampling, etc.

      In order to solve these problems, many companies have introduced factory personnel positioning systems to conduct final sampling and summary through precise location services. The purpose is to have real-time tracking of each personnel activity and work status analysis to improve safety management and optimize production efficiency.

      The entire system is based on UWB positioning technology as the underlying data sensing. The tags in the device communicate with the base station through UWB pulse signals. The base station collects the tag information data and forwards it to the positioning server. The data is processed by the algorithm of the positioning engine to accurately Location information is transmitted to upper-layer applications through open API interfaces.

Features of UWB factory personnel positioning system

1. High speed transmission

The base station equipment performs data backhaul through 5.8G Wi-Fi and Ethernet, ensuring high-speed data transmission.

2. High positioning accuracy

UWB ultra-wideband positioning technology is used to meet the high-precision positioning needs of factory personnel. Compared with other technologies, it has high-precision positioning, reaching an average of 30cm.

3. Ultra-low power consumption

For the tag side, using a low-power design, the human tag can work for 1 month in ToF mode and 3 months in TDoA mode.

4. Distributed systems

The system adopts distributed construction, which can meet the simultaneous construction of multiple factories and branch factories. It is ultimately managed uniformly in the cloud, making data collection and analysis more convenient.

The factory personnel positioning management system mainly manages management from two aspects: safety and efficiency.

1. Personnel safety control

Breaking into the danger zone

In production enterprises, there are some dangerous areas with high temperature and high pressure. In chemical enterprises, there are toxic gases, liquids, etc. Employees without relevant qualifications are not allowed to enter these areas. When illegally breaking into these areas, the system and personnel positioning tags will be An alarm should be generated, and the alarm will not be released until you leave, to avoid physical harm caused by unusual intrusions.

High-risk work area

Even when qualified people enter some high-risk areas, they must also have working time requirements. Once the working time exceeds the set working hours, the system will remind you through an alarm or directly remove the risk factors in the dangerous area.

quick rescue

When people are injured, quick rescue is required. One is to press the rescue button on the tag by the worker himself, and the other is to use the automatic sensing of the tag to limit the amount of time it takes to remain motionless before generating an alarm to remind the backend management staff to initiate rescue in real time to avoid the risk of accidents caused by too long a time. Workers die.

Quick gathering and roll call

When the entire project encounters a serious accident, it is necessary to quickly gather employees, conduct a roll call, confirm the real-time location of employees who have not arrived, and implement rescue to avoid casualties;

2. Improvement of personnel efficiency

We can deeply dig into the work efficiency of each worker based on the real-time location of each worker in the factory, and know the difference in work efficiency of each person, so as to facilitate subsequent continuous improvement and efficiency optimization; based on the location and processing procedures, we can understand each worker's work efficiency. The time required for the processing process, evaluation of production efficiency, etc.

operating hours

By positioning people, we can accurately understand

a. Attendance and vacation status can be related to the salary system

b. Daily working hours at the work station

c. Realize refined management in terms of the composition of daily working time periods, production line work, machine maintenance, production collaboration, management meetings, etc.

Working time and efficiency management and control

Operation time and efficiency control are mainly related through time and output

a. The time required for a certain process of processing or assembly, or the quantity of output during working hours

b. Compare with others of the same type of work to find room for improving work efficiency

c. Comparison of work efficiency in different time periods

Through horizontal and vertical comparison, find the optimization space and optimize it.

Factory personnel positioning system performance indicators

UWB positioning base station

Factory personnel real-time positioning systems locate base stations for adoption data backhaul over 5G Wi-Fi and Ethernet. Supports standard IEEE802.3af PoE power supply, which can be centrally managed through a PoE switch and can also be powered through a DC interface. As a return channel, the data of the positioning tag can be sent to the positioning server.
