The signal switching module 2 selects to switch the signal path to either the signal acquisition module 3 or the signal processing module 4 based on the control commands. When the signal path is switched to the signal acquisition module 3, the first and second signal sensors acquire audio and video signals respectively, and transmit the signals to the signal switching module 2 via shielded cables.

The short-range communication module 9 transmits signals to nearby terminal devices, the alarm module 10 issues an audible and visual alarm signal when an abnormal signal is detected, and the remote communication module 11 transmits signals to the remote monitoring center.

[0058] Through the above specific implementation methods, this utility model realizes the multi-functionality and intelligence of the signal acquisition and forwarding device, solves the problems of traditional devices having single functions, low transmission efficiency and susceptibility to interference, significantly improves the stability and reliability of the system, and meets the needs of modern security systems for efficient management.

[0059] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further explained below in conjunction with a specific application scenario.

[0060] In practical applications, a dedicated security signal acquisition and forwarding device was deployed in the perimeter security system of a large industrial park. This park requires 24 / 7 monitoring of its perimeter environment and the ability to flexibly adjust signal acquisition and processing modes according to different environmental conditions to ensure the system's efficient operation and reliability.

[0061] First, the main control unit 1 receives operational status information from external security devices, such as alarm signals from infrared beam sensors or vibration fiber optics, via wires. The microprocessor inside the main control unit 1 analyzes the received information and generates control commands, which are then sent to the signal switching module 2. The double-pole double-throw switch in the signal switching module 2 selects whether to switch the signal path to the signal acquisition module 3 or the signal processing module 4 based on the control commands. When the park is under normal monitoring, the signal path is switched to the signal acquisition module 3; however, when an anomaly is detected, the signal path switches to the signal processing module 4 for further signal processing.

[0062] The first and second signal sensors in signal acquisition module 3 are responsible for acquiring audio and video signals, respectively. The high-sensitivity microphone integrated into the first signal sensor can capture subtle sounds within the park, such as the sound of climbing fences or striking metal. Its preamplifier circuit performs preliminary amplification of the acquired audio signal to improve the signal-to-noise ratio. The CMOS image sensor inside the second signal sensor is used to acquire real-time video footage of the park's perimeter. The analog-to-digital converter circuit converts the analog video signal into a digital signal for subsequent transmission and processing. The acquired signals are transmitted to signal switching module 2 via shielded cables to ensure that the signal is not affected by external electromagnetic interference during transmission.

[0063] Meanwhile, the infrared sensor and light intensity detector in the environmental perception module 5 monitor the environmental conditions of the park perimeter. The pyroelectric sensor inside the infrared sensor can detect human activity, such as someone approaching the fenced area. Its signal conditioning circuit filters and amplifies the detected signal to improve detection accuracy. The photoresistor inside the light intensity detector is used to detect the current light intensity. Its amplification circuit converts the detection result into an electrical signal and transmits it to the auxiliary switching module 6 through a wire. Based on the received environmental perception data, the auxiliary switching module 6 automatically selects whether to transmit the data from the signal acquisition module 3 or the signal processing module 4 to the display unit 7. For example, in daylight conditions, the auxiliary switching module 6 prioritizes transmitting the video signal to the display unit 7; while at night or in low light conditions, it prioritizes transmitting the audio signal to the display unit 7, so that security personnel can quickly assess the situation on site.

[0064] When the signal path switches to signal processing module 4, the third and fourth signal sensors further process the audio and video signals, respectively. The low-pass filter inside the third signal sensor filters the audio signal to remove high-frequency noise, while the operational amplifier amplifies the signal to enhance its strength. The digital signal processor inside the fourth signal sensor denoises the video signal and simultaneously optimizes the image quality using an image enhancement algorithm module, such as improving contrast and sharpness, resulting in a clearer video image. The processed signal is transmitted to signal switching module 2 via a shielded cable, and then selectively transmitted to display unit 7 by auxiliary switching module 6.

[0065] In certain special circumstances, such as when the main signal path fails, the backup switching module 8 automatically switches to the backup path via a trigger signal from the environmental sensing module 5, ensuring the continuity of signal transmission. The redundant relays and fault detection circuits inside the backup switching module 8 can quickly identify faults in the main signal path and transmit the signal to the short-range communication module 9 via the backup path. The Bluetooth chip and antenna inside the short-range communication module 9 transmit the signal to nearby terminal devices, such as handheld terminals used by security personnel, so that timely countermeasures can be taken.

[0066] Furthermore, when the main control unit 1 detects an abnormal signal, such as human activity detected by the infrared sensor or abnormal sounds in the audio signal, the main control unit 1 will trigger the alarm module 10 to issue an audible and visual alarm signal. The buzzer and LED indicator inside the alarm module 10 are connected to the main control unit 1 via a relay, enabling security personnel to be alerted to abnormal situations immediately. The remote communication module 11 transmits signals to the remote monitoring center via 4G communication technology. Its internal 4G communication chip and SIM card slot support high-speed data transmission, ensuring that the monitoring center can obtain real-time dynamic information about the perimeter of the park.

[0067] Through the above steps, this invention enables the signal acquisition and transmission device to operate multifunctionally and intelligently in complex environments. For example, during the day when there is sufficient sunlight, the device prioritizes acquiring and transmitting video signals so that security personnel can intuitively understand the situation on site; while at night or in low-light conditions, the device prioritizes acquiring and transmitting audio signals to compensate for the shortcomings of video surveillance. In addition, through the coordinated work of the environmental perception module 5 and the auxiliary switching module 6, the device can automatically adjust the signal acquisition and processing mode according to changes in environmental conditions, thereby significantly improving the adaptability and reliability of the system.

[0068] In summary, this invention solves the problems of traditional devices, such as limited functionality, low transmission efficiency, and susceptibility to interference, through the coordinated operation of its modules, thus meeting the demands of modern security systems for efficient management. The device demonstrates excellent stability and reliability in practical applications, providing strong technical support for perimeter security in industrial parks.

[0069] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
