The necessity and function of an emergency telephone in a pipe gallery _ an effective communication environment

In general, a large number of power cables and a certain amount of electromechanical equipment are set up in a relatively narrow space in the urban integrated pipe gallery. These power and communication cables, together with the self-owned electrical equipment in the pipe gallery, create a complex electromagnetic environment and unstable wireless signal transmission in the pipe gallery.

Moreover, the pipe gallery itself is underground, making it difficult for mobile phone signals to enter. Therefore, emergency telephone of the pipe gallery should be set up to ensure a smooth and effective communication environment in the pipe gallery.

One emergency telephone host is set in each fire partition of the pipe gallery, and 1~2 auxiliary machines are set according to the structure in the fire partition.In the control center, an emergency telephone main control machine is set up in a sleeve gallery, and emergency telephones in each division are managed and configured for registration.

The emergency telephone system is connected with fiber-optic ring network to ensure that failure at one point does not affect the work of other telephones.Under the premise of unimpeded fiber ring network, all emergency telephone hosts in the pipe gallery can work off-line without the equipment in the control center to adapt to the complex and changeable situation in the pipe gallery.

The emergency telephone of the pipe gallery can not only be used for communication between personnel of different fire zones in the pipe gallery.It can also communicate with the outside of the pipe gallery through the program-controlled switch set in the control center, so as to meet the communication needs of the maintenance personnel and the outside of each gallery unit.

Through the connection function of emergency telephone of the pipe gallery and the outside world, the maintenance personnel can not only send the alarm through the automatic control system of the pipe gallery, but also directly dial the alarm phone to the outside world to give the manual alarm when the pipe gallery is in danger.

In addition, the emergency telephone system of the pipe gallery can be integrated with the broadcast system by installing a waterproof loudspeaker, which can be combined with the telephone system to realize the function of Shouting and intercom to each section/the whole pipe gallery.
