DSP9000 IP Public Address Solution for Bus Rapid Transit (BRT)

DSP9000 IP Public Address Solution for Bus Rapid Transit (BRT)

1. Solution Description

Bus Rapid Transit (BRT) is a new public passenger transport system between BRT and Normal Bus Transit. Leveraging on high-quality, high-efficiency, low energy consumption, low pollution and low-cost, BRT fully embodies the development concept of people-oriented and harmonious society. The advanced public transportation system is inseparable from high-quality service facilities; the public broadcasting system is already an indispensable component module, providing high-efficient, pleasant, comfortable and safe services of background music, paging broadcast and fire alarm for BRT. However, a BRT line includes about twenty or thirty stations, with a total length of tens of kilometers; the conventional analog broadcasting system cannot bear such a large regional span, with heavy wiring works. Therefore, the network broadcasting system is the most suitable system for BRT. In order to develop broadcasting solutions suitable for high-speed rail, subway and BRT projects with large spans and difficult wiring, DSPPA has continued to invest a large number of resources in research and development for many years to overcome various technical difficulties and develop a variety of digital network broadcasting systems. The DSP9000 network system is one of the digital network broadcast systems; after years of iterative updates, now the system can be used efficiently and stably in the BRT. The network host is easy to learn and use, with beautiful design; the system transmits audio signals on the LAN using the DSPPA protocol compatible with TCP / IP, with a transmission distance of tens of kilometers, which can save the heavy engineering wiring with the existing LAN.

3. Attainable Functions

1. Main control room (Computer room)

The system is a set of two-way audio sound reinforcement system transmitted by pure digital network, which can break through the tradition that the traditional public broadcast system can only be downloaded and can only be controlled through the computer room, and solve the intercom problem between stations and between the station and the general control room. In addition, the network host is controlled remotely by LAN in the host room, to realize the overall control and management of each station and resource allocation in the main control room; for example, it can play different background musics for different BRT stations and set each station different zones. The system also adopts GPS time calibrator, which can make accurate broadcast time of the host room possible. And the system has a fire linkage function.

2. Broadcasting center and sub-control room

The sub-control room can be connected to the LAN of the system through the computer after installing the software, to realize some functions of the control system. It can realize the zone management and paging between the stations, the timing function under the unattended operation, the priority setting, and uploading to the host; the broadcast center can broadcast temporary or emergency notifications to some or all bus stations, and can realize the intercom with the terminals of the parking lots, which can achieve real-time management.

3. Parking lot

The parking lot can use the remote paging microphone in the field to page the stations on the relevant routes and talk to the broadcast center, and can receive new messages or report to the broadcast center at any time.

4. Bus station

The speaker of the entire system is mounted at each bus station for business announcements or passenger guidance at the bus station. When there are many passengers on the station, the station staff will take the form of inflow and batch release according to the actual situation to maintain the order of the platform; and broadcast regular safety warnings, including “Do not cross the yellow line when waiting for the BRT; Please enter the BRT platform from the safety gate; It is strictly forbidden to walk on the lane and cross the lane to enter the opposite lane and platform, so as to avoid accidents.”.
