[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0019] To address the problem that existing environmental gas monitoring systems and visual monitoring systems are often set up separately, requiring separate maintenance and resulting in low maintenance efficiency, this invention provides a monitoring system for environmental safety monitoring in factories. The system includes a data acquisition module and an interactive module. The data acquisition module can simultaneously detect gas concentration parameters in the environment and on-site video image information. The video image information is uploaded to a visual inspection host computer for safety monitoring. The gas concentration data is transmitted to a second main control module, which performs concentration safety judgment and triggers an alarm module when the gas concentration exceeds a threshold. Simultaneously acquiring on-site gas concentration data and image data combines two types of safety monitoring, improving the timeliness of abnormal state detection and enhancing safety. Furthermore, the operation and control of the environmental data acquisition module and the video image acquisition module can be integrated into the first main control module, improving system integration.

[0020] Specifically, such as Figure 1 As shown, the monitoring system in this embodiment includes a data acquisition module 100 and an interactive module 200. The data acquisition module 100 is used for acquiring raw data, and the interactive module 200 is used for analyzing the raw data and issuing an alarm indication when the gas concentration exceeds a preset concentration threshold.

[0021] The acquisition module 100 includes a first main control module 110, an environmental data acquisition module, and a video image acquisition module 130. The first main control module 110 is communicatively connected to the environmental data acquisition module and the video image acquisition module 130. The video image acquisition module 130 is also communicatively connected to the visual inspection host computer 300 through a high-definition multimedia interface.

[0022] The interactive module 200 includes a second main control module 210 that can provide an alarm control signal output when the input gas concentration exceeds a preset concentration threshold, and an alarm module 220. The gas concentration signal input terminal of the second main control module 210 is communicatively connected to the first main control module 110, and is also communicatively connected to the environmental data acquisition module through the environmental data channel of the first main control module 110. The alarm control signal output terminal of the second main control module 210 is connected to the control terminal of the alarm module 220. The second main control module 210 acquires the gas concentration in real time from the acquisition module 100, compares it with the preset concentration threshold, and when the gas concentration exceeds the concentration threshold, the state of the alarm control signal flips, driving the alarm module 220 to issue an alarm.

[0023] In this embodiment, the monitored environmental parameters include carbon dioxide, formaldehyde, combustible gas, PM0.3, PM2.5, PM10, temperature, humidity, carbon monoxide, ammonia, nitrogen dioxide, and hydrogen sulfide. Among them, the sensors for collecting formaldehyde, PM0.3, PM2.5, PM10, temperature, humidity, and hydrogen sulfide are digital sensors, while the sensors for collecting other parameters are analog sensors. To facilitate data storage, in this embodiment, the environmental data acquisition module includes a sensor unit 121, an analog-to-digital conversion unit 122, and a data acquisition and storage unit 123.

[0024] The sensor unit 121 includes a digital acquisition signal output terminal and an analog acquisition signal output terminal. The digital acquisition signal output terminal is communicatively connected to the first main control module 110, and the analog acquisition signal output terminal is connected to the input terminal of the analog-to-digital conversion unit 122. The output terminal of the analog-to-digital conversion unit 122 is communicatively connected to the first main control module 110. The first main control module 110 is also communicatively connected to the acquisition and data storage unit 123.

[0025] The digital acquisition signal obtained by the sensor unit 121 is directly stored in the acquisition data storage unit 123 through the first main control module 110. The analog acquisition signal is converted into a digital signal through the analog-to-digital conversion unit 122, and then stored in the acquisition data storage unit 123 through the first main control module 110. That is, the raw gas data acquired by the sensor unit 121 is digitally stored in the acquisition data storage unit 123, which facilitates the review and analysis of accidents based on the stored historical data.

[0026] To facilitate data retrieval, in this embodiment, the gas concentration signal input terminal of the second main control module 210 is also connected to the data acquisition and storage unit 123 via a communication bus. The second main control module 210 directly reads the raw data stored in the data acquisition and storage unit 123. When the first main control module 110 malfunctions due to an on-site accident, the interactive module 200 can directly access the data acquisition and storage unit 123, ensuring alarm reliability. Furthermore, it ensures the speed of gas concentration monitoring and alarm, guaranteeing the immediate detection of abnormal environmental conditions.

[0027] To facilitate the installation of the data acquisition module 100 and the interaction module 200 in a real factory environment, in this embodiment, the data acquisition module 100 further includes a first wireless communication module 140, and the interaction module 200 further includes a second wireless communication module 241 and a communication mode button switching module 230. The first main control module 110 is communicatively connected to the first wireless communication module 140, and the second main control module 210 is communicatively connected to the second wireless communication module 241. The communication mode switching control terminal of the second main control module 210 is connected to the communication mode button switching module 230.

[0028] The communication mode of the second main control module 210 can be controlled by the interactive buttons of the communication mode switching module 230. In wired communication mode, the second main control module 210 directly accesses the data acquisition and storage unit 123 through the IIC bus. In wireless communication mode, the second main control module 210 communicates with the first main control module 110 through the first wireless communication module 140 and the second wireless communication module 241. When the second main control module 210 obtains the data stored in the data acquisition and storage unit 123 through the first main control module 110, or when the main control module 110 obtains the output data of the sensor unit 121 and the analog-to-digital conversion unit 122, it directly sends it to the second main control module 210, which can improve the timeliness of data transmission.

[0029] The acquisition module 100 provides power to each module through the first power module 150. The first power module 150 includes a battery, a first transformer unit and a second transformer unit. The first transformer unit is used to power the analog sensor in the sensor unit 121, and the second transformer unit is used to power the electronic components other than the analog sensor. This avoids the switching noise of the digital sensor from interfering with the operation of the analog sensor, thereby ensuring the reliability of the analog sensor.

[0030] Linear voltage regulators can be selected for both the first and second transformer units to ensure power accuracy and thus the reliability of the acquired data. A 12V lithium battery can be selected, drawing power from the mains via a transformer.

[0031] The video image acquisition module 130 includes a camera driving circuit for driving the camera to work. The video image data acquired by the camera is uploaded to the vision inspection host computer 300 through a high-definition multimedia interface. The vision inspection host computer 300 uses an intelligent vision recognition system to determine the safety of the on-site environment, such as monitoring whether on-site personnel are wearing safety helmets, whether there are cracks in the material conveying pipeline, and whether there is abnormal smoke on site.

[0032] When a safety issue arises, the visual inspection results can be communicated to the first main control module 110, which then sends an alarm indication signal to the second main control module 210. The second main control module 210, based on this alarm indication signal, drives the alarm module 220 to sound an alarm. Sharing the alarm module 220 saves on alarm hardware setup requirements. Alternatively, the visual inspection host computer 300 can also directly trigger an alarm via its own alarm module, facilitating its deployment at the camera site for on-site alarms, alerting on-site construction personnel to immediate abnormalities. The interactive module 200 controls alarms based on gas concentration. Furthermore, through two-way communication between the visual inspection host computer 300, the acquisition module 100, and the interactive module 200, abnormal detection results from the interactive module 200 can be sent to the visual inspection host computer 300, controlling it to issue a safety alarm on-site. Setting up dual-end alarms at both the on-site and remote management terminals facilitates simultaneous responses from multiple parties to abnormal situations, improving safety.

[0033] Alarm module 220 includes, for example, a buzzer and a warning light, which trigger an alarm through a combination of sound and light. The buzzer driver circuit includes, for example... Figure 4 As shown, the operation of the buzzer BUZ1 is controlled by the alarm control signal BEEP.

[0034] To facilitate proactive prevention, in this embodiment, the interactive module 200 also includes a third wireless communication module 242. The second main control module 210 is also connected to the data graphical host computer 400 through the third wireless communication module 242. It can upload gas concentration data to the data graphical host computer 400 and display historical information and trends of gas concentration through the data graphical function of the data graphical host computer 400. This can be used to predict potential safety hazards in advance. For example, when minor damage during material transportation causes slow leakage of material, the gas concentration corresponding to the leaked material increases slowly. The characteristic of slow increase in concentration can be used to predict the existence of an anomaly in advance.

[0035] The interactive module 200 and the acquisition module 100 can be set separately and can be powered independently. Correspondingly, the interactive module 200 also includes a second power module 250. The second power module 250 includes a USB interface circuit. The power line of the USB interface circuit is connected to the power supply terminals of the second main control module 210, the alarm module 220, the second wireless communication module 241 and the third wireless communication module 243, and provides the corresponding working power directly through an external power adapter and USB power supply protocol.

[0036] The first main control module 110 and the second main control module 210 can be implemented using Xilinx Artix-7 series field-programmable gate arrays, and the analog-to-digital converter unit 122 can be implemented using the ADS1115 chip, and so on. Figure 2 As shown, the analog-to-digital conversion unit 122 also filters the power supply through an LC filter circuit to ensure the reliability of the analog-to-digital conversion. The data acquisition and storage unit 123 can be implemented using a 24C02 chip, and as shown... Figure 3 As shown, the data acquisition and storage unit 123 is also connected to the power supply via a diode to achieve power protection.

[0037] The monitoring system provided by this utility model is used for environmental safety monitoring in factories. It includes a data acquisition module and an interactive module. The data acquisition module can simultaneously detect gas concentration parameters in the environment and on-site video image information. The video image information is uploaded to a vision inspection host computer for safety monitoring. The gas concentration data is transmitted to a second main control module, which performs concentration safety judgment and triggers an alarm module when the gas concentration exceeds a threshold. Simultaneously acquiring on-site gas concentration data and image data combines two types of safety monitoring, improving the timeliness of abnormal state detection and enhancing safety. Furthermore, the operation and control of the environmental data acquisition module and the video image acquisition module can be integrated into the first main control module, improving system integration.
