1. Play background music (in the production plant area, especially in the night duty room, background music needs to be played).
2. Broadcast and paging can be performed on any partition (any broadcast paging can be performed within the broadcast area, etc.).
3. The horn loudspeaker system has intercom function, etc. (intercom paging function is provided in special production positions).
4. Fire-fighting linkage (manually or by fire-fighting control to be forced into the fire-fighting broadcast state, producing fire-fighting alarms, etc.).
5. The system equipment can be turned on regularly, and the music can be played at a fixed time (the whole system can be controlled uniformly).
2. Design scheme of public broadcasting for large factories:
The factory PA Loudspeaker is mainly used to provide daily background music and daily broadcast notifications for the factory area, and can further realize the function of zone control broadcast. We choose the IP digital network broadcasting system in the HUSPA broadcasting series according to the actual requirements and characteristics of the factory for public broadcasting, as well as the advanced nature, reliability and economy of the equipment. In addition to the reasonable, complete and concise configuration of the system, the rich experience of our company's intelligent system is combined, and a complete set of solutions is proposed, so that this project can fully meet the requirements of investors. Broadcasting is mainly distributed in various production positions in the factory, outdoor broadcasting points, and production scheduling centers. For the convenience of broadcasting, the broadcasting system is divided into several zones (see the table for details), so that zoned broadcasting or zoned paging can be performed under different circumstances.
1. Install network radio wall-mounted terminals and speakers (for daily radio paging and background music playback) at production posts.
2. Intercom paging terminals are installed in the guard room and production scheduling center of special production posts (broadcast paging can be performed to any broadcast point in the broadcast and two-way intercom can be realized with each intercom center).
3. Outdoor broadcast points (under its requirements, install 6 outdoor broadcast points in line with the layout of its factory area, and later need to expand the points, used in the whole factory business broadcast and emergency broadcast, such as the weekly production alarm sounding regularly, etc. ).
3. System function description:
Covers all the functions of traditional broadcasting systems, including background music playback, leader speeches, broadcast announcements, automatic bells, and broadcast radio programs. The system is based on IP network, follows the TCP/IP protocol for multiple uses, makes full use of IP network resources, and avoids repeated installation of lines. The place where the Ethernet interface can be connected to the digital broadcasting terminal can truly realize the multi-network integration of broadcasting and computer network.
1. Multi-partition broadcast architecture, arbitrary unicast control:
The inside of the factory area is divided into broadcast zones according to the different production positions, and each production scheduling position is divided into separate zones. The production of the scheduling center requires timely and reasonable production scheduling. Timely broadcast to notify the real-time situation of each production control position or drowsiness reminder during night shift work. Integral broadcasts in all outdoor areas, etc.
2. All-weather scheduled playback and bell at work and rest time:
The bell will be played regularly during the all-weather work and rest time in the factory area, and the daily production safety alarm will be played regularly.
3. Real-time on-demand background music:
Each production scheduling post office can request background music, volume control, etc. to the main control center in real time and locally, and the night shift staff can broadcast radio and on-demand background music to relieve difficulties.
4. Radio program monitoring:
Monitor speakers are installed in the sub-control center of the host room, which can monitor all broadcast programs in real time.
5. Alarm broadcast linkage:
Combined with the network alarm host to receive the alarm signal, and pre-set the alarm mode on the server software, the alarm linkage function can be performed. Through the network alarm, various alarm signals are received, and the pre-set areas and content are broadcast to the corresponding broadcast area, which can realize partition alarm, whole area alarm, or interactive alarm in adjacent layers and adjacent areas. The alarm system has the highest priority in the system. No matter the system is running in any working state, once the alarm is triggered, it can force the alarm to the area to which it belongs. The alarm ringtone can be made or recorded by itself (such as guiding emergency evacuation, etc.). Alarms have the highest priority in the entire system.
The emergency broadcast system and the background music broadcast system share the control host, speakers and distribution network, and according to the fire division, in the event of a fire or emergency, they can be automatically and forcibly switched, and have sufficient volume to the accident layer (accident area) Broadcast fire accident with the upper and lower floors (adjacent areas). The configuration of the power amplifier of this system can meet the requirement of 24-hour continuous broadcasting to all areas.
6. Terminal power control
The power supply system of each network broadcast terminal is controlled by the network broadcast control center. According to whether the broadcast signal has the function of automatically turning on its own power supply system and external control power supply, the standby power is less than or equal to 0.3W.
7. Permission level settings
The software can set up multiple users to use this system software or VOD terminal, which is managed by the administrator, and the administrator assigns the system account and password to each user, as well as the use authority and the number of terminals. There are high and low levels, the administrator has the highest use authority, and only the administrator can set or change the setting parameters of the system.
8. Network paging and intercom functions:
The production scheduling center and each production scheduling post are matched with network two-way intercom terminals, and the real-time voice intercom is carried out with the production scheduling center in real time, and the production and operation status of each production post is reported to the production scheduling control center in time, which is convenient for production scheduling. The center will talk about the real-time adjustment and planning of the overall production system. The intercom voice can be saved in real time, which is convenient for later inspection.
9. Remote sub-control function:
The control computer of the dispatch center installs the sub-control software and performs data connection with the main control server. Remote sub-control management can be carried out, and daily broadcast business functions can be sub-controlled on the sub-control computer.
10. System backup function
The main control server runs a genuine operating system and has a system-specific backup and restoration tool. When the system needs to be updated in the later use process, just follow the operating instructions to restore the system. No need to redo the operating system. The main control software also provides software data backup function. After the broadcast master control software is set for various broadcast tasks, a comprehensive broadcast software data backup can be performed on the broadcast software, and periodic broadcast software data backup can also be performed on the software during use. , If you need to update the software in the later use process, you only need to restore the software data backup, and all the settings and task programming of the broadcast software will be restored as new, and there is no need to re-set each broadcast.
11. Time switch
The host can set the opening and closing time according to the usage time of the broadcasting system. Ensure the cleanliness of the working environment and increase the service life of the host.
12. Easy to operate and intuitive display.
Equipped with a large-screen LCD display that can display the current working status in real time, and has the function of man-machine dialogue. Large LCD display during working hours, and the operation password can be set in the Chinese menu to ensure the safe operation of the system.
