Technical Field

[0001] The present invention relates to the technical field of substation perimeter security, and in particular to a substation perimeter security system. Background Art

[0002] In the current substation security system, insufficient security is a prominent problem. Many existing systems rely on external networks or unstable transmission media, which may not only lead to the loss of critical data, but also expose sensitive information of the substation to the risk of leakage. In addition, the limited monitoring range means that some areas of the substation may not be effectively monitored. These blind spots may become potential entry points for intruders. At the same time, since many existing systems have delays in processing and responding to alarms, this may give intruders enough time to carry out destructive behavior. Summary of the invention

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0024] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0025] Example 1, reference Figure 1 to Figure 2, which is the first embodiment of the present invention, provides a substation perimeter security system, including a signal acquisition module 100, the signal acquisition module 100 includes a vibration fiber collector 101, a fiber switching device 102, it is worth noting that the fiber switching device 102 is equivalent to a junction box; a monitoring alarm module 200, the monitoring alarm module 200 includes an alarm keyboard host 201, an audio and video speaker 202, a linkage module 203, a DVR hard disk recorder 204, and a camera 205; the signal acquisition module 100 and the monitoring alarm module 200 are connected to a network switch 206 through a network cable to realize the linkage of the entire device. It is worth noting that the signal acquisition system and the monitoring alarm system are connected to the network switch 206 through a network cable, and then a network cable is led out through the network switch 206 to connect a PC computer installed with a system host computer 207207 software to realize the linkage of the entire device. When an intrusion is detected in a certain defense zone, the alarm system alarms and displays the alarm area information, and the corresponding defense zone camera 205 is also linked to upload the imaging situation of the alarm defense zone, so as to accurately locate the intrusion alarm position of the defense zone.

[0026] Specifically, the vibration optical fiber collector 101 is connected to the optical fiber switching device 102 through five optical jumpers.

[0027] The optical fiber switching device 102 connects five optical fibers to four defense zone packages 103 and one terminal package 104 through an internal optical splitter through a vibration optical cable 109, and forms a four-defense zone non-closed loop.

[0028] Furthermore, the optical fibers inside the defense zone package 103 and the terminal package 104 are connected to the vibration optical fibers to form five complete optical circuits.

[0029] It should be noted that one terminal package 104, four defense zone packages 103, optical fiber switching equipment 102, and vibration optical fiber collector 101 are sequentially connected through vibration optical cable 109 to form an optical signal collection loop, and finally the collected optical signal is transmitted to the vibration optical fiber collector 101 through the optical loop for signal processing by the central processing module 106. The central processing module 106 integrates a photoelectric conversion module, a signal amplification module, a filtering module, and a data acquisition module. By preprocessing and digitalizing the signal, the quality and reliability of the signal are improved. After the data is processed, it is transmitted through the wiring, and finally the data is displayed on the display screen 108.

[0030] Example 2, reference Figure 1 to Figure 2 This embodiment is different from the first embodiment in that: the vibration fiber collector 101 includes an optical jumper interface 105, a central processing module 106, a cable interface 107, and a display screen 108; the optical jumper interface 105 and the optical fiber switching device 102 are connected through an optical jumper.

[0031] Specifically, the optical jumper interface 105 includes Z1105a, a first interface 105b, a second interface 105c, a third interface 105d, and a fourth interface 105e.

[0032] Furthermore, the optical fiber switching device 102 is internally integrated with an optical splitter, and five optical fibers are separated and connected to four defense zone packages 103 and one terminal package 104 through vibration optical cables 109, thereby forming a four-defense zone non-closed loop.

[0033] It should be noted that the alarm keyboard host 201 has a digital display screen 108, a control keyboard, and a microprocessor. When receiving the vibration signal collected by the acquisition system, the microprocessor processes the signal and determines whether it reaches the alarm threshold. If the alarm threshold is exceeded, the sound and light speaker 202 automatically alarms.

[0034] The linkage module 203 is linked with the DVR 204 and the camera 205 to collect image information of the entire defense zone. The image signal of the defense zone is automatically uploaded to the host computer 207207. When an intrusion is detected in a certain defense zone, the image signal of the defense zone is automatically uploaded to the host computer 207207, and the alarm area information is displayed to accurately locate the intrusion position of the defense zone.

[0035] The upper computer 207207 software can change the system alarm threshold and intuitively display the defense zone status information through video charts.

[0036] The rest of the structure is the same as that of Example 1.

[0037] Example 3, reference Figure 1 to Figure 2 This embodiment is different from the above embodiments in that: the defense zone package 103 and the terminal package 104 are both integrated with optical circuit splitters, and have input interfaces and output interfaces respectively. The optical fibers inside the defense zone package 103 and the terminal package 104 are connected to the optical fiber switching device 102 through vibration optical cables to form five complete optical circuits, forming a complete vibration signal acquisition system.

[0038] Specifically, the alarm keyboard host 201 is provided with a display screen 108, a control keyboard and a microprocessor. When receiving the vibration signal collected by the acquisition system, the microprocessor processes the signal and determines whether it reaches the alarm threshold. If the alarm threshold is exceeded, the sound and light speaker 202 automatically alarms.

[0039] Furthermore, the linkage module 203 cooperates with the DVR 204 and the camera 205 to collect image information of the entire defense zone, and the image signal of the defense zone is automatically uploaded to the host computer 207207. When an intrusion is detected in a certain defense zone, the image signal of the defense zone is automatically uploaded to the host computer 207207, and the alarm area information is displayed to accurately locate the intrusion position of the defense zone.

[0040] The upper computer 207207 software can change the system alarm threshold and intuitively display the defense zone status information through video charts.

[0041] The rest of the structure is the same as that of Example 2.

[0042] It should be noted that the vibration optical fiber collector 101 and the optical fiber switching device 102 in the present invention are connected through five optical jumpers. The optical fiber switching device 102 connects the five optical fibers to four defense zone packages 103 and one terminal package 104 through the vibration optical cable 109 through the internal optical splitter to form a four-defense zone non-closed loop. The optical fibers inside the defense zone package 103 and the terminal package 104 are connected to the vibration optical fibers to form five complete optical loops, forming a complete set of vibration signal collection system. The alarm keyboard host 201, the sound and light speaker 202, the linkage module 203, the DVR hard disk recorder 204, and the camera 205 constitute a monitoring alarm system. The signal acquisition system and the monitoring alarm system are connected to the network switch 206 via a network cable, and then a network cable is led out through the network switch 206 to connect to the PC computer installed with the system host computer 207207 software, so as to realize the linkage of the whole device. When an intrusion is detected in a certain defense zone, the alarm system will alarm and display the alarm area information. The corresponding defense zone camera 205 will also be linked to upload the imaging situation of the alarm defense zone, so as to accurately locate the intrusion alarm position of the defense zone.

[0043] The principle of the present invention lies in the interaction mechanism between optical signals and vibrations in optical fibers. The backscattered light in the optical fiber is used to detect vibration signals. That is, external vibrations, pressure, etc. will cause the optical cable vibration sensor or the vibrating optical cable to deform. The change in the optical path causes the optical signal transmitted by the vibrating optical cable to change. The collector detects the change in the optical signal, then processes the detected signal and extracts the characteristic value of the intrusion signal. When the characteristic value meets the alarm condition, an alarm signal is output.
