OBT Park Scenic Area Emergency PA System Design
According to the planning and management needs of the park, the park scenic area needs to be divided into multiple broadcasting areas by means of various scenic spots and sightseeing routes, so as to achieve independent zone control. The whole system is mainly composed of the central computer room of the park scenic spot, the PA control point, the help alarm point, the ordinary broadcasting point and the transmission line. The specific design given by the OBTPA design team is as follows:
Central computer room: set in the park scenic area monitoring center, configure system server, platform software, establish the whole system data exchange platform, realize terminal function configuration. Configure remote talkback microphones for daily broadcast notifications, etc. In the event of an emergency, it should be used for command, information broadcast, and police, to improve the safety management of the park scenic area.
PA control point: The system is based on the park network platform. It is equipped with a remote paging talk box in the security room of the entrance and exit of the park, and the duty room of each attraction. The broadcast control points of the whole area are set up for emergency broadcast and emergency help.
Help alarm point: According to the management needs of the park scenic spot, an emergency help alarm terminal is arranged at the intersection of the road, the lakeside and the small road of the whole park scenic spot, so that when the passenger encounters the difficulty, the quick alarm function can be realized through the help alarm terminal.
Ordinary broadcasting point: outdoor waterproof sound column or grass speaker can be arranged between the green area, nearby jungle and hillside in the scenic spot of the park, and the campus broadcast point can be established in sections to broadcast broadcast notice, background music, and warm reminders.
Transmission line: The system is based on the park network LAN platform, which adopts two parts: network transmission + analog transmission line. The front-end network transmission is mainly the connection between the central equipment room and each sub-control point and each terminal IP power amplifier, all using full digital signal transmission; The back-end analog part is mainly used to amplify the signal transmission of each part terminal signal. This part of the line has a relatively short transmission distance and can be transmitted by analog line. Adopting the all-digital audio and video centralized control management system, under the premise of ensuring high-quality sound quality, the problem of traditional broadcast ultra-long-distance signal transmission is completely solved, and the management control is superior, and the control point can be set in the park scenic spot network. Any location and support cross-domain control
