3. Intercom function
The terminal only needs to press the PTT key to immediately make a group call similar to the cluster call; the terminal in the same group can hear the speech of the initiating terminal. The intercom function has fast connection speed, and the called terminal can answer automatically to improve the response speed.
4. MDS system features
1)Distributed: it allows multiple dispatchers to be deployed in one system, which not only meets the requirements of cross regional deployment, but also solves the problem of insufficient capacity of a single device;
2)Dual machine hot standby not only the central IP dispatcher can carry out dual machine hot standby to ensure the safe and stable operation of the system, but also the dispatching terminal can provide dual registration mode for registration. When registering to the central IP dispatcher, it can register to the local server, dispatcher or IP-PBX according to the needs, so as to ensure the smooth communication inside and outside the pipe gallery to a large extent.
3)Rescue guidance and emergency broadcast.
It can be used to popularize safety knowledge, and can also be used as a life-saving guidance system in case of emergency. In case of emergency, the voice file set in the emergency plan can be played directly to realize the rapid guidance of emergency.
4)Effectively integrate with other monitoring systems to realize emergency linkage.
Power grid security monitoring system, digital industrial television monitoring system and other monitoring and monitoring systems can effectively integrate with the whole system through dispatching machine to realize emergency linkage function. It provides alarm collection interface to effectively connect with various underground monitoring and alarm systems. For example, when the gas monitoring system in the pipe gallery detects toxic gas, the gas monitoring system can send corresponding data to the MDS dispatching system, and the MDS dispatching system triggers the corresponding alarm linkage system to quickly inform the personnel in the pipe gallery to evacuate by broadcasting or other means.
5)Call recording function.
The recording system is connected to the dispatching host through the recording interface to realize the recording of specified calls; it can record multiple calls at the same time; it can preset the recording time to record certain numbers; it can also record specified numbers. The server provides file query and management functions.
6)User defined function group and permission management.
It can be divided into different groups to support flexible scheduling and control of each member the same authority has different operation ability.
7)Video scheduling function.
Through the visual terminal, the dispatcher can monitor the scene image. The video monitoring terminal can also be linked with the voice equipment to make synchronous voice and video calls.
8)Emergency communication meeting.
Dispatchers can quickly initiate a meeting by dialing the trigger number; the system allows users to initiate a meeting through mobile phones and fixed phones, so that commanders can conduct on-site command without waiting for the situation report to make decisions in front of the dispatching desk; the conference security authentication function is enabled to prevent unauthorized personnel from initiating a meeting casually; mobile phones and fixed phones are also used as conference terminals, The availability and compatibility of the system are improved
