Ensure the communication between the inside of the pipe corridor and the outside world.
2. Inside the pipe corridor
Emergency phone deployment: Emergency telephone boxes are set up in the pipe gallery at certain intervals to make the pipe gallery have emergency calls throughout the entire process. Considering that the various application cabins in the pipe gallery transmit various signals and materials, all emergency calls in the pipe gallery The equipment should have industrial-grade waterproof, dust-proof, corrosion-resistant and anti-oxidation capabilities. At the same time, it should have an explosion-proof function for emergency telephones placed in the gas cabin.
Due to the complexity of the internal environment of the pipe gallery, mobile phone signals are difficult to receive stably. Therefore, as the main communication method in the pipe gallery, the emergency telephone system must have a high degree of stability and redundancy. For this reason, when designing the plan, we adopted ring networking for all emergency telephone equipment nodes in the pipe gallery, provided explosion-proof equipment for gas tanks, and provided high-grade waterproof and corrosion-resistant emergency telephone equipment for sewage and urban water tanks. , According to different cabin environments, different equipment selections ensure the stable operation of the entire system. At the same time, the ring networking mode can guarantee the availability of emergency phones in each application cabin to the greatest extent. When the network of a single device node is abnormal, it will not affect the normal communication and use of other nodes.
Broadcasting system: the waterproof speaker is used as the speaker of the broadcasting system, and a speaker is installed at a certain interval in the pipe gallery to ensure that the sound effect can be covered throughout the pipe gallery. The waterproof speaker is connected to the emergency telephone box, and the emergency telephone box provides the network Broadcast signal. The broadcast system provided by us has intelligent sleep and wake-up functions, real-time detection of the broadcast signal from the control host of the monitoring center, when there is no signal input,
