Tianjin, located on the shore of bohai Sea, is an international port city, northern economic center and ecological city. Tianjin Public Security Fire Brigade has 4 departments (including 27 department-level organizations and 19 units directly under departments), which are command, Political Department, Logistics Department and Fire Prevention Supervision Department. It has 5100 officers and soldiers at present. Over the years, generations of firefighters have protected the safety of Tianjin with their sweat, blood and even their lives. Since 1991 alone, the Tianjin Fire Brigade has responded to and dealt with more than 200,000 police, dispatched 449,000 fire trucks and 3.462 million firefighters, rescued and evacuated more than 15,000 trapped people, and protected national, collective and individual property worth more than 10 billionRMB.
In the construction of fire-rescue digital system designed by Saturn Electronics, wireless data transmission and on-site image transmission are the key points. Therefore, relying on4G automatic switching technology, a special virtual network and digital circuit for fire fighting have been built and opened to transmit the data needed for fire fighting and rescue, and the command and dispatch of fire fighting and rescue in the whole city has been realized. Now the digital system of fire fighting and rescue in Tianjin has been put into use. This means that the on-board wireless image transmitting equipment and image transmitting equipment will be used to transmit the image back to the fire fighting and rescue scene within the city, and the fire commander can command the fire fighting and rescue battle according to the image returned from the fire dispatching command center at the two levels of corps and detachment.
