Description

A device for capturing images of illegal intrusion into rural domestic sewage treatment facilities Technical Field

[0001] This utility model relates to the field of rural sewage treatment and security technology, and in particular to an image capture device for illegal intrusion into rural domestic sewage treatment facilities. Background Technology

[0002] Rural domestic sewage treatment facilities are scattered and manual inspections are inefficient, making it difficult to detect illegal intrusion and vandalism in a timely manner. Current mainstream monitoring methods have the following shortcomings:

[0003] Traditional video surveillance relies on manual interpretation or simple motion detection, which is easily affected by environmental factors such as swaying plants and small animal activities, resulting in frequent invalid alarms.

[0004] Fixed whitelist-based identity verification (such as access cards) cannot adapt to the frequent changes in maintenance personnel and is not linked to maintenance periods, which can easily lead to situations where "legitimate personnel are mistakenly identified as intruders" or "illegal personnel impersonate maintenance personnel."

[0005] High-performance video analytics equipment (such as facial recognition systems) and continuous network connectivity are costly and difficult to deploy on a large scale in facilities that are widely distributed in rural areas. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this utility model provides an image capture device for illegal intrusion into rural domestic sewage treatment facilities. This is a low-cost, highly reliable illegal intrusion monitoring solution that achieves accurate identity verification, low false alarm rate detection, and rapid response across multiple platforms in complex environments. To achieve the above objectives, this utility model adopts the following technical solution:

[0007] A device for capturing images of illegal intrusion into rural domestic sewage treatment facilities, comprising:

[0008] The intrusion detection system employs at least one PIR infrared sensor to detect changes in the infrared characteristics of the human body within the protected area around the clock.

[0009] An image capture system, including a camera capable of capturing images, is used to acquire images of intrusion targets;

[0010] RFID authentication devices, including RFID readers and active RFID tags, are used to verify the legitimacy of a person's identity;

[0011] The alarm module includes an audible and visual alarm for on-site warning and remote alarm purposes.

[0012] The intelligent data acquisition and control module is used to collect data from each module, perform logical judgments, and control alarms and image transmission.

[0013] The intelligent acquisition and control module is electrically connected to the intrusion detection system, the image capture system, the RFID authentication device, and the alarm module, and interacts with the cloud platform through the wireless communication module.

[0014] Furthermore, the PIR infrared sensor has a detection angle ≥120°, a detection distance >5m, and is equipped with an environmental interference filtering algorithm that triggers a response only for human movement signals lasting ≥20 seconds.

[0015] Furthermore, the camera capable of capturing images is a visible light camera with a resolution of ≥1080P, and is equipped with a fill light that supports automatic photosensitive triggering or remote control triggering.

[0016] Furthermore, the RFID reader is an ultra-high frequency RFID reader with a working frequency of 860-960MHz and a signal coverage radius of >20m; the active RFID tag is powered by a button battery and is worn by authorized maintenance personnel.

[0017] Furthermore, the intelligent acquisition and control module includes:

[0018] The data acquisition module is used to receive data from intrusion detection systems, RFID authentication devices, and image capture systems.

[0019] The data calculation module is used to compare RFID identification information with the maintenance plan time period;

[0020] The alarm control module is used to trigger the start and stop of the audible and visual alarm.

[0021] The wireless communication module supports 4G network communication and is used to synchronize the legitimate identity database, operation and maintenance plans, and upload alarm data with the cloud platform.

[0022] The data storage module is used for local storage of intrusion events, captured images, and authentication records.

[0023] Furthermore, the alarm module's audible and visual alarm supports dual working modes: it continuously alarms for 60 seconds after an intrusion is triggered, and then switches to intermittent alarm mode until the intrusion is resolved.

[0024] Furthermore, the device typically only has the intrusion detection system in standby mode, while the other modules are activated upon detecting an intrusion signal, and it supports battery power or solar power.

[0025] Furthermore, the intrusion detection system is fixed to the top of the fence or wall of the rural sewage treatment facility, covering the main entrances and key equipment areas; the image capture system is installed through a stainless steel bracket, with a viewing angle covering the facility entrance and key areas.

[0026] Furthermore, the cloud platform is used to store a database of legitimate RFID identities and maintenance plan time periods, and to receive alarm information uploaded by the intelligent acquisition and control module, supporting the sending of SMS or APP alarm notifications to the maintenance manager.

[0027] Furthermore, by integrating PIR infrared sensing technology with RFID identity authentication technology, illegal intrusion can be verified twice, filtering out environmental interference from small animals and swaying plants.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. A dual verification mechanism combining infrared sensing and RFID eliminates environmental interference and reduces false alarm rate;

[0030] 2. Remote whitelist updates are faster and more efficient than traditional on-site configuration, improving the efficiency of dynamic identity management;

[0031] 3. It only operates in infrared standby mode, resulting in low daily power consumption. It is more energy-efficient than full-time video surveillance, significantly optimizing power consumption and cost. Attached Figure Description

[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0037] As shown in Figures 1 and 2, this utility model embodiment proposes an image capture device for illegal intrusion into rural domestic sewage treatment facilities, comprising:

[0038] Intrusion detection system 1 employs at least one PIR infrared sensor to detect changes in the infrared characteristics of the human body in the protected area around the clock;

[0039] Image capture system 2 includes a camera capable of capturing images for intrusion targets;

[0040] RFID identification device 3, including RFID reader and active RFID tag 12, is used to verify the legitimacy of personnel identity;

[0041] Alarm module 4 includes an audible and visual alarm for on-site warning and remote alarm.

[0042] The intelligent data acquisition and control module 5 is used to acquire data from each module, perform logical judgments, and control alarms and image transmission.

[0043] The intelligent acquisition and control module 5 is electrically connected to the intrusion detection system 1, the image capture system 2, the RFID identification device 3 and the alarm module 4, and interacts with the cloud platform 11 through the wireless communication module 9.

[0044] The working principle is:

[0045] Intrusion detection activated:

[0046] The PIR infrared sensor continuously scans the protected area and uses a Fresnel lens to focus human infrared radiation. When it detects a human movement signal that lasts for ≥20 seconds (filtering out short-term interference such as small animals and fallen leaves), it sends an intrusion trigger signal to the intelligent acquisition and control module 5.

[0047] RFID dynamic identity verification:

[0048] The intelligent module activates the RFID reader / writer, scanning active RFID tags within a radius > 20 meters.

[0049] Legitimate scenario: If the RFID tag ID is in the legitimate identity database synchronized in the cloud, or if the current time is within the scheduled maintenance period (with an error of ±5 minutes), it is determined to be legitimate maintenance, the personnel ID and entry time are recorded, and subsequent detection is suspended;

[0050] Unauthorized scenario: If RFID tag 12 is not detected or the identity / time period does not match, an unauthorized intrusion process is triggered;

[0051] Emergency Response and Data Reporting:

[0052] Control the camera to capture images (resolution ≥ 1080P, automatic fill light), and upload them to the cloud platform via 4G network 11;

[0053] Activate the audible and visual alarm, which will sound continuously for 60 seconds, then switch to intermittent mode (e.g., sounding the alarm for 10 seconds every 30 seconds) until the intrusion is resolved;

[0054] Alarm information, including images and timestamps, is pushed synchronously to the operation and maintenance manager in the cloud, enabling multi-dimensional alerts from both on-site and remote locations.

[0055] By employing a dual mechanism of infrared sensor filtering for invalid triggers and RFID dynamic identity and time-series verification, it accurately distinguishes between legitimate maintenance and illegal intrusion. At the same time, it reduces energy consumption through a low-power design (only waking up high-power modules during intrusion) to meet the needs of rural scenarios.

[0056] In this embodiment, the PIR infrared sensor has a detection angle ≥120°, a detection distance >5m, and is equipped with an environmental interference filtering algorithm, triggering a response only for human movement signals lasting ≥20 seconds. The PIR infrared sensor used is HC-SR501 (detection angle 120°, distance 7m). Two sensors are symmetrically installed on the top of the fence, 5 meters apart, and connected to the GPIO interface of the smart module via DuPont wires.

[0057] In this embodiment, the camera capable of capturing images is a visible light camera with a resolution ≥1080P, and is equipped with a supplementary light that supports automatic photosensitive triggering or remote control triggering. The camera is a Hikvision DS-2CD3T26WD-I3 (1080P, PoE powered), mounted on a stainless steel bracket at a height of 2.5 meters on the right side of the entrance, and connected to the switch interface of the intelligent module via an RJ45 network cable.

[0058] In this embodiment, the RFID reader is an ultra-high frequency RFID reader with an operating frequency of 860-960MHz and a signal coverage radius >20m. The active RFID tag 12 is powered by a button battery and worn by authorized maintenance personnel. The RFID reader is an Impinj Speedway R420 (frequency 902-928MHz, coverage radius 25 meters), vertically mounted on the outside of the electrical control cabinet with the antenna facing the entrance, and connected to the serial port of the intelligent module via an RS485 cable. The RFID tag 12 is an Alien ALN-9640 (3V button battery, 1-year lifespan), packaged as a badge, and worn by maintenance personnel.

[0059] In this embodiment, the intelligent acquisition and control module 5 includes:

[0060] The data acquisition module 6 is used to receive data from the intrusion detection system 1, the RFID authentication device 3, and the image capture system 2;

[0061] Data calculation module 7 is used to compare RFID identity information with the operation and maintenance plan time period (error ±5 minutes).

[0062] Alarm control module 8 is used to trigger the start and stop of the audible and visual alarm.

[0063] The wireless communication module 9 supports 4G network communication and is used to synchronize the legal identity database, operation and maintenance plan and upload alarm data with the cloud platform 11;

[0064] Data storage module 10 is used for local storage of intrusion events, captured images, and authentication records.

[0065] The intelligent acquisition and control module 5 uses a Raspberry Pi 4B (quad-core Cortex-A72, 4GB memory, integrated Waveshare 4G HAT), which is fixed inside the electrical control cabinet and has an external 4G antenna. It calls the drivers of each module through Python scripts.

[0066] In this embodiment, the audible and visual alarm of the alarm module 4 supports dual working modes: after an intrusion is triggered, it continuously alarms for 60 seconds, then switches to intermittent alarm mode (alarming for 10 seconds every 30 seconds) until the intrusion is resolved. The audible and visual alarm uses an FS-120DB (volume 120dB, strobe light 100 lumens), is installed on the top of the electrical control cabinet, and is connected to the GPIO interface of the intelligent module via a relay module.

[0067] The illegal intrusion image capture device operates with only the intrusion detection system 1 in standby mode during normal operation. The other modules are activated upon detecting an intrusion signal and support either battery or solar power. The power supply system can be configured as a 2V 100W solar panel + 12V 50Ah lithium battery + MPPT controller. The solar panel is installed on the top of the facility, the lithium battery is placed inside the electrical control cabinet, and the controller integrates overcharge protection.

[0068] In this embodiment, as shown in Figure 2, the intrusion detection system 1 is fixed to the top of the fence or wall of the rural sewage treatment facility, covering the main entrance and key equipment area; the image capture system 2 is installed by a stainless steel bracket, and the viewing angle covers the facility entrance and key areas.

[0069] In this embodiment, the cloud platform 11 stores a database of legitimate RFID identities and maintenance plan time periods, and receives alarm information (including captured images, intrusion timestamps, and coordinates) uploaded by the intelligent acquisition and control module 5. It supports sending SMS or APP alarm notifications to the maintenance manager. By integrating PIR infrared sensing technology with RFID identity authentication technology, illegal intrusion behavior is dually verified, filtering out environmental interference from small animals and swaying plants, thus reducing the false alarm rate.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
