However, at the same time, different areas may require the bell or announcement in some areas while others do not.

[0019] The following is combined with Figures 1 to 8 , further describe this application plan:

[0020] The intelligent partitioner includes a chassis and a mainboard. The mainboard is equipped with a power module 1, a main control module 2, an input module 3, an input control module 4, an output module 5, a multi-level network port 485 communication module 6, and an address code selection module 7. The power module 1 is used for AC / DC conversion to power the mainboard. It includes a mains interface 11, a power switch 12, a transformer 14 for converting 220V mains power into 24V AC power, and a power circuit 15 for rectifying the 24V AC power into a DC+24V DC voltage. A filter unit 13 is provided on the input side of the transformer 14.

[0021] The input module 3 includes four normal input interfaces 31 and four emergency input interfaces 32; the output module 5 includes 16 output interfaces 51, corresponding to 16 independent output partitions CH1-CH16, each output interface 51 is equipped with a relay 52, the common end of the relay 52 is connected to the output interface 51, the normally closed end is connected to the normal input interface 31, and the normally open end is connected to the emergency input interface 32; for example, see the attached Figure 7 In the independent partition CH1, the normally closed end of the relay JD17 is connected to the 8th pin of the normal input interface J11, and the normally open end is connected to the 8th pin of the emergency input interface J7. The common end of the relay JD17 is connected to the interface J1. The relay JD17 is controlled by the main control module 2 to switch the connection line. When the connection state of the relay JD17 is switched, it is connected to either the 8th pin of the normal input interface 31 J11 or the 8th pin of the emergency input interface 32 J7. Specifically, each normal input interface 31 is connected to four output interfaces respectively, so that the same sound source can have four output partitions (arranged to four broadcast areas), and these output partitions can be played separately or synchronously. For example, Figure 7 The 8 pins of J11 in the normal input interface 31 are connected to relays JD17-20 respectively, so that the audio source connected to the 8 pins can be connected to the independent output partitions CH1-CH4, so that the selection and playback can be made through the control button 41. Similarly, each emergency input interface 32 is also connected to four output interfaces, for example, Figure 7 Pin 8 of J7 in the emergency input interface is connected to relays JD17-20 respectively to achieve emergency audio cut-in of the four output partitions.

[0022] The input control module 4 includes a control button 41 corresponding to each output interface. The control button 41 is connected to the main control module 2. Each time the control button 41 is pressed, a level signal is sent to the main control module 2 (for example, by grounding to lower the level of the corresponding pin of the main control module 2). The main control module 2 then responds by controlling the corresponding relay 52 to switch the connection line. The control buttons 41 are arranged on the front panel of the chassis, and each control button 41 is respectively equipped with a status indicator light 42. The status indicator light 42 is connected to the main control module 2 and indicates the current output status of the corresponding output interface by changing the color or on and off of the status indicator light (for example, green indicates normal input, red indicates emergency input).

[0023] The multi-level network port 485 communication module 6 is provided with two network interfaces, which are used to realize cascade control between machines of the same model to form a large-scale multi-channel digital control function; the address code selection module 7 is used to configure the address of the current device to realize the function of non-duplication and non-interference of addresses when machines of the same model form a large-scale multi-channel digital control function; the AC power interface 11, normal input interface 31, emergency input interface 32, output interface 51, network interface of the multi-level network port 485 communication module 6, and address code selection module 7 are all arranged on the back panel of the chassis.

[0024] In terms of circuit design, the main control module 2 includes a CPU 21 and a relay driver chip 22 located between the CPU 21 and the relay 52. ​​A DC bias voltage (provided by a bias circuit 24) is applied to the input and output of the relay driver chip 22 to enhance driving force. Furthermore, several hub ICs 23 are located between the output of the relay driver chip 22 and the relays 52. Each input pin of the hub IC 23 is connected to the output of the relay driver chip 22, while each output pin of the hub IC 23 is connected to the relays 52. This also ensures driving force for the relays 52 and optimizes the motherboard wiring.

[0025] The above preferred embodiments should be regarded as examples of the implementation methods of the present application scheme. Any technical deductions, replacements, improvements, etc. that are identical or similar to the present application scheme or made based on it should be regarded as within the scope of protection of this patent.
