[0029] To address the current lack of specialized testing equipment for sound and light dispersal systems, which necessitates manual operation and testing of various devices, thus easily disturbing the surrounding environment, and making it difficult to quickly determine whether a fault lies with the controller itself or the connected equipment, resulting in time-consuming and labor-intensive troubleshooting, we offer a sound and light dispersal controller testing instrument.

[0033] like Figures 1 to 6 As shown, this embodiment provides a sound and light dissipation controller tester, including a drive power module 1, a microcontroller module 2, an audio module, and a camera module that are electrically connected to each other. The microcontroller module 2 is electrically connected to a button assembly, a screen assembly, a PTZ input port, and a light input port. The audio module includes an operational amplifier circuit 301, a power amplifier circuit 302, and a test speaker 303 that are electrically connected in sequence. The input terminal of the operational amplifier circuit 301 is connected to an audio input port. The camera module is connected to a video output port. The PTZ input port, light input port, audio input port, and video output port are all connected to a cable socket 6. The cable socket 6 is connected to the sound and light dissipation controller via a detachable plug cable (not shown in the figure).

[0034] Among them, the cable socket 6 can use the same cable interface as the one used for docking the acoustic and optical dispersive device on the acoustic and optical dispersive controller to be tested, so as to facilitate the connection of the tester through the original interface on the acoustic and optical dispersive controller and ensure the efficiency of equipment docking.

[0035] An optocoupler 7 is installed on the circuit between the gimbal input port and the microcontroller module 2. The gimbal's up, down, left, right, and reset operations output level values ​​from different pins. Therefore, the optocoupler 7 is installed to isolate and protect the microcontroller module 2, preventing it from being damaged by the gimbal control signal of the audio-visual dispersive controller.

[0036] The light input port is connected to the microcontroller module 2 via the normally open interface of the light signal relay 8. The normally closed interface of the light signal relay 8 is connected sequentially to the RS485 receiver chip 201 and the microcontroller module 2. The microcontroller module 2 is also connected to the control input interface of the light signal relay 8. Since the light control signals output by different models of sound and light dispersal controllers include push-button switch combination logic, RS485 signals, etc., the light signal relay 8 is provided to facilitate operators in selecting the correct light signal detection path before testing by controlling the release or activation state of the light signal relay 8 using the push-button assembly, based on the current controller model being tested.

[0037] In microcontroller serial communication, since TTL level is typically used, the light control signal composed of multiple button switch states can be directly read by microcontroller module 2. However, when the light control signal is an RS485 signal, RS485 receiver chip 201 is needed for level conversion, converting the RS485 level to TTL level to enable RS485 communication for microcontroller module 2. In this embodiment, the RS485 receiver chip 201 is model SP3485, a +3.3V low-power half-duplex RS485 transceiver with a data transmission rate of up to 10Mbps, making it a key component in RS485 communication.

[0038] The audio input ports are multiple, each electrically connected to the microcontroller module 2. Each audio input port is connected to an audio module via an audio relay 9, and the microcontroller module 2 is connected to the control input interface of the audio relay 9. Since the audio output of the sound and light dispersal controller is divided into types such as anti-riot recording, strong sound dispersal audio, and microphone pickup, which generally correspond to different pins on the cable socket 6, similar to the light signal, relay switches are used to correspond to different pins for various types of audio.

[0039] The camera module includes a video relay 401 and a test camera 402. The power supply module 1 is connected to the test camera 402 via the video relay 401. The microcontroller module 2 is connected to the control input interface of the video relay 401. The test camera 402 is connected to the cable socket 6. This allows operators to easily control the on / off state of the test camera 402 during testing by using a button assembly to link the microcontroller module 2 and the video relay 401.

[0040] The drive power module 1, microcontroller module 2, operational amplifier circuit 301, power amplifier circuit 302, and video relay 401 are all mounted on the main circuit board 10. The design, in which all circuit components are uniformly mounted on the main circuit board 10, achieves high integration and facilitates assembly.

[0041] The main circuit board 10 is installed in the protective enclosure 11, and the test speaker 303 is installed on the inner side of the protective enclosure 11. A enclosure panel 12 is detachably installed on the protective enclosure 11. The button assembly, screen assembly, cable socket 6, and test camera 402 are all installed on the enclosure panel 12. The enclosure panel 12 also has a power switch 101 and a power interface 102 for connecting to the drive power module 1. All components are installed in the protective enclosure 11, making the tester easy to carry and highly durable. Furthermore, all interactive components are located on the enclosure panel 12, making it ergonomically designed for ease of use.

[0042] Both the button assembly and the screen assembly are mounted on a touchscreen 5, which is electrically connected to the microcontroller module 2. The touchscreen 5 includes a gimbal signal display area 501 and a light signal display area 502. Both display and button operation functions are provided by the touchscreen 5, reducing equipment hardware costs. Furthermore, touch buttons have a longer lifespan than physical buttons and have no limit on the number of presses. The gimbal signal display area 501 and the light signal display area 502 can replace physical gimbals and warning lights to indicate the signal status output by the sound and light dispersal controller, allowing staff to easily check and confirm whether the signal output is normal.

[0043] The microcontroller module 2 is an STM32F407ZG. An operational amplifier circuit 301 is electrically connected to an audio filtering circuit 304. The output of the audio filtering circuit 304 is connected to the analog-to-digital converter (ADC) pin of the microcontroller module 2. An audio spectrum display area 503 is provided on the touchscreen 5. Besides directly playing sound using the test speaker 303, the sound signal, after being processed by the audio filtering circuit 304, is converted to digital signal by the microcontroller module 2 and displayed on the touchscreen 5 in the form of an audio spectrum. Therefore, even if the test speaker 303 does not play sound, the operator can still confirm whether the sound and light dissipation controller is outputting a sound signal by observing the screen. The STM32F407ZG is an STM32 microcontroller with built-in analog-to-digital converter (ADC) functionality, which helps simplify the components on the main circuit board 10 of the testing instrument and reduce the hardware cost of the equipment.

[0044] The microcontroller module 2 is electrically connected to an ST-link debugger (not shown in the figure), and the ST-link debugger is connected to a USB female connector 103. In this embodiment, since an STM32 microcontroller is used, a USB female connector 103 can be installed on the chassis panel 12, and the ST-link debugger can be used to connect to the microcontroller module 2. This allows external computers and other terminal devices to easily access the microcontroller module 2 via the USB female connector 103 to edit the tester's built-in program.

[0045] The principle for conducting the test is as follows:

[0046] Sound detection is achieved by amplifying the audio through a designed power amplifier circuit 302, and then displaying the audio through a test speaker 303. Switching between audio inputs, such as microphone voice transmission and memory card audio recording / playback, is controlled by relay switching.

[0047] The light detection is achieved by directly reading the control logic of the sound and light dispersal controller, which is composed of multiple button switch states, through the microcontroller module 2, or by reading the data frames of different types sent by the RS485 communication bus after conversion by the RS485 receiver chip 201. Thus, eight light states, such as weak white light, strong white light, white light flashing, white light off, alternating flashing of colored lights, simultaneous flashing of colored lights, and colored lights off, are displayed on the touch screen 5.

[0048] The gimbal control detection is achieved by detecting the 24VDC level output of the sound and light dissipation controller through the microcontroller module 2. The gimbal's up, down, left, right, and reset operations output level values ​​from different pins. The STM32F407ZG microcontroller operates at 3.3V, so the microcontroller module 2 is isolated and protected by the optocoupler 7 to achieve safe detection.

[0049] The camera display function of the sound and light dissipation controller is tested by using a test camera 402 with radio frequency output to provide real-time images. When the staff sends a camera-on signal using the touch screen 5, the microcontroller module 2 controls the video relay 401 to turn on the power of the test camera 402.

[0050] The specific testing steps include:

[0051] 1. Sound Test

[0052] Pressing the audio playback button on the sound and light dispersal controller allows the anti-riot recording to play normally; connecting the megaphone allows the voice to play normally; pressing the strong sound dispersal button allows the dispersal audio to play. Observe whether the spectrum in the audio spectrum display area 503 is normal.

[0053] 2. Gimbal Testing

[0054] When the gimbal rises when the sound and light dissipation controller is pressed, the words "Gimbal rises" can be observed in the gimbal signal display area 501 of the touch screen 5 (the same applies to down, left, right, and reset).

[0055] 3. Lighting test

[0056] When the white light control button of the sound and light dispersal controller is pressed, the light signal display area 502 of the touch screen 5 will sequentially display the states of weak white light, strong white light, white light flashing, and white light off. Similarly, the colored light control button will sequentially display the states of alternating colored light flashing, colored lights flashing together, and colored lights off. The microcontroller module 2 reads different data frames sent by the controller to determine the light state.

[0057] 4. Camera Test

[0058] When the test camera 402 is activated via the touch screen 5, a real-time image can be displayed on the screen of the tested sound and light dissipation controller.

[0059] The above description is a further detailed explanation of the present utility model in conjunction with specific preferred embodiments. It should not be assumed that the specific implementation of the present utility model is limited to these descriptions. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present utility model.
