background
As the security during large-scale sports events held in stadiums has higher and higher requirements for professional wireless intercom system communication, the use of simple wireless intercom relay systems can no longer meet the communication needs. When an emergency occurs, the simple system lacks dispatching function and has no corresponding emergency handling mechanism, which is prone to safety accidents. In order to eliminate such hidden dangers, it is necessary to establish a system with complete scheduling functions and clear voice.
Wireless intercom system solution for stadiums
Sports venues usually use portable micro-cluster base stations to build a system for large-scale events to ensure good local voice and data services. At the same time, they can interact with the command center through communication vehicles, and can be scheduled in all directions.
Large-scale sports venues are usually crowded with people, and some emergencies may also occur. Through the use of emergency communication equipment, communication equipment of different standards and different frequency bands can be interconnected, and real-time feedback to the command center through the emergency communication vehicle. At the same time, DS-6801 is equipped with an image transmission program. When an accident occurs, the staff can bring emergency individual equipment to the scene, and the scene situation can be transmitted back to DS-6801 through the wireless link in real time, and then sent to the DS-6801 via the communication vehicle. Command center.
System Features
Clear voice, high frequency point utilization
The wireless intercom trunking system is used for calls in the stadiums, which guarantees the clarity of the voice and the stability of the signal to the utmost. At the same time, using TDMA dual time slot technology, a single frequency point can support two calls, which greatly improves the frequency point utilization.
Powerful scheduling function
The command center can perform a variety of scheduling functions, including group dispatch for combining group calls, dynamic reorganization of combining individual calls into group calls, and basic individual and group calls. At the same time, the dispatching station can dynamically see the work trajectory and real-time location of the dispatched person on the display screen for visual dispatch. The dispatching station also has the functions of forced demolition and forced insertion, which can issue instructions for itself when the business is busy.
Complete emergency mechanism, multi-mode response throughout the network
The system has a complete emergency mechanism, which enables communication equipment of multiple standards to be interconnected, and can respond quickly in an emergency. Through the front-end individual soldiers, the image signal is transmitted to the emergency communication vehicle terminal for reception in real time, and then sent to the command center in real time to make a timely response.
Multiple transmission methods
The communication vehicle can interact with the command center through different links. Through public network base stations and image transmission base stations, the image information obtained from the front can be transmitted back to the command center in time. And through the satellite link, it can also transmit necessary voice communication and video information, which is convenient for the command center to dispatch.
What is an Explosion-proof Screen Protector?
Now Mobile Phone Screen Protector can be seen everywhere in our daily life. The most common one should be "Tempered Glass Screen Protector", but I'm still relatively unfamiliar with "Explosion-proof Screen Protector for mobile phones". Next, I will briefly introduce Explosion-proof Screen Protective Film. membrane.
The Mobile Phone Explosion-proof Screen Protector is mainly made of imported PET material and a layer of silicone coating. Since the thickness of the silicone coating is thicker than that of ordinary screen protectors, it can decompose external force under strong collision to buffer the impact and prevent the mobile phone from being accidentally hit. The glass panel of the mobile phone is broken and scattered, which reduces the hidden damage of the glass panel and ensures the safety of users. That is to say, "Mobile Phone Explosion-proof Screen Protector" is not to prevent the phone screen from exploding, but to prevent the phone screen from being impacted, it can decompose the external force and reduce the chance of the phone screen breaking. The anti-impact, anti-scratch, anti-wear, etc. of the mobile phone Explosion-proof Protective Film can protect the screen to a certain extent compared to the general PET and PE Mobile Phone Screen Protectors.
