The function of the pipe gallery fiber optic telephone is to provide good communication conditions for the underground pipe gallery

The pipe corridor optical fiber telephone is now a very important device in the construction and development process of the city. It is related to the important conditions of the communication equipment in the construction of our urban underground pipe corridor project. In fact, the function of the tube corridor optical fiber telephone is to provide a good communication function for the tube corridor. Let's let Shenzhen 800 Tong Intelligent to give you a detailed introduction. The function and use requirements of the tube corridor optical fiber telephone are as follows:

Role: Provide communication guarantee for operation and maintenance

With the progress of urbanization, more and more cities in China have begun to build underground comprehensive pipe gallery projects, because most of the underground comprehensive pipe gallery is built at a depth of 4 to 5 meters from the surface or even deeper. The role of fire safety and real-time monitoring is particularly important. In this case, it is very necessary to build a complete communication system. Therefore, the integrated pipe corridors under construction in China basically choose fiber phones as the fixed communication of the pipe corridors. system.

In view of the special environment of the underground pipe gallery, what requirements should the pipe gallery fiber optic telephone have?

1. In view of the long transmission distance of the pipe gallery, the optical fiber transmission mode should be adopted;

2. In view of the constant temperature and tide characteristics of the pipe gallery, the electrical products entering the gallery must have a protection level of no less than IP65. This is determined by the characteristics of the pipe gallery constant temperature and constant tide. There are many microorganisms in the pipe gallery. The corrosion of electronic components will be very serious, so the electrical equipment entering the corridor needs to have a very good protection level.

3. As a communication security system, it is also an emergency telephone system.

4. The system should be able to communicate with the external public network. Not only can the calls in the pipe gallery be made, but also the phone users of the external public network can call into the pipe gallery, and it should be in control. Any call made in the gallery will not affect the use of other phones, and the call is truly non-blocking.

5. The system must have the function of self-checking, and the system must ensure that each phone in the system is in good condition, so that the fixed-line communication system needs to have monitoring functions for its terminals and intermediate connection equipment, and can be used in any composition in the system. Some including but not limited to switches, optical fiber transceivers, optical transceivers, telephones, etc., when failures occur, they will receive feedback soon and report to the operation and maintenance personnel for repair.

6. The system adopts the cascading mode. Any connected device in the middle provides a transmission signal to the next connected device. In this way, once an intermediate device fails, the network cannot be collapsed or paralyzed due to a single failure. The cascade mode technology can be used. The entire network can continue to be used, bypassing the point of failure to ensure the normal use of the network.

7. It should also have a recording function to provide a basis for the investigation and evidence collection of emergencies in the pipe gallery.

8. It has explosion-proof function. Now many pipe galleries are designed with gas warehouses. It is clearly stipulated in GB50838-2015 that gas warehouses are classified as second-class explosion-proof places. Therefore, the telephone in the pipe gallery fiber-optic telephone fixed-line communication system must have national-level experiments The room has an effective explosion-proof qualification, which can meet the explosion-proof requirements of Class II places.

Combining the current technological development and underground pipe gallery management requirements, design a set of professional multimedia intercom broadcasts for the underground pipe gallery, including wired emergency intercom, broadcast propaganda, emergency broadcasting, dispatch management, video linkage, office communication, and external network intercommunication. Dispatching management system, pipe gallery fiber phone system can deeply integrate application management with other systems, improve the information management level of pipe gallery, effectively reduce enterprise operation and management costs, and improve daily work efficiency and emergency response capabilities.
