The business scope of Guangzhou Water Investment Group Co., Ltd. includes water pollution control; Sewage treatment and recycling; Natural water collection and distribution, etc. The underground space of buried water purification plant is large, the structure is complex, and the sewage treatment process is complex. It is easy to produce and accumulate toxic, flammable and explosive gases such as hydrogen sulfide, ammonia and methane, which brings multiple risks such as poisoning and suffocation to front-line operators. Traditional management methods can no longer meet the increasing risk and management needs. Guangzhou water purification company takes phase III of Lijiao buried water purification plant as the pilot to use modern industrial Internet technology. Combine big data analysis with UWB positioning technology, set UWB positioning base stations, wear smart bracelets, and create an employee life safety monitoring system with the function of "life safety monitoring + accurate personnel positioning". Once a dangerous situation occurs, the personnel press the alarm button, and the system will send an alarm, which can quickly and accurately locate the location of the personnel in distress, rescue the personnel within the golden rescue time, increase the survival probability of the personnel in distress and reduce the accident loss.
3D visual precise positioning
3D visual map, 1:1 restore the site structure framework, locate the base station and bracelet, and use TDOA / TOF ranging technology to realize real-time and accurate positioning of personnel. It can quickly view the information and positioning of alarm personnel in the 3D map of the system, quickly organize and mobilize nearby personnel or organize teams for rescue, and realize multiple linkage and rapid emergency response。
Life safety monitoring
The smart bracelet can collect the heart rate, blood oxygen and other vital signs of all employees, operators and visitors entering the underground space, warn the visitors that they are not allowed to enter the key areas, locate the underground staff in real time, and display the real-time position, working hours and working track of the staff in real time on the monitoring system. When the system detects that the personnel's life safety index is in an abnormal state, it will send an alarm. After the personnel have physical abnormalities, they can actively press the bracelet SOS alarm key to send a distress signal to the platform system. Double alarm mechanism to ensure personal safety.
Combined with the accurate positioning function, it derives the auxiliary management functions such as regional restriction management (electronic fence) and historical track playback, restricts the access of personnel in key areas, traces the historical track records of personnel, strengthens the digital, information and intelligent management level of buried areas, and improves the ability of risk management and control.
Send alarm: the system can send the specified reminder to the bracelet, and the bracelet will give the specified mode reminder through the built-in buzzer and vibrator.
Low power reminder: the positioning device has the function of self detecting battery power. When the power of the device is low, it will prompt to charge in time.
Attendance management: Based on the characteristics of high-precision positioning of the system, positioning equipment can be added at any position such as the factory entrance to realize the attendance auxiliary function, record the access to the factory and record the time. It can also be used in combination with access control and all-in-one card.
Group management: the system supports personnel group management. Personnel in different groups have different permissions.
