However, there may be some unknown dangers such as harmful gases in confined spaces, which may cause human discomfort. Workers may not be able to call for help in time when in danger. Therefore, the work safety of workers needs to be further improved. Utility Model Content

[0009] By adopting the above technical solutions, the application of equipment such as carbon monoxide detectors and methane gas sensors can comprehensively cover common harmful gases in confined spaces, thereby improving the accuracy and comprehensiveness of environmental monitoring.

[0010] Optionally, both the external machine and the internal machine include an industrial control mainboard module, a converged communication gateway module and a power management module. The converged communication gateway module is installed on the industrial control mainboard module, and the power management module is electrically connected to the converged communication gateway module.

[0011] By adopting the above technical solutions, this modular design makes the device's functions more clear and independent, facilitating subsequent maintenance and upgrades. The industrial control motherboard module serves as the core control unit, responsible for data processing and command issuance; the converged communication gateway module integrates multiple communication protocols, ensuring stable data transmission; and the power management module ensures stable power supply to each module, improving the device's reliability and stability.

[0013] By adopting this technical solution, the wristband, as a monitoring device terminal, is portable and real-time, capable of monitoring the safety status of workers in real time. The wristband interface design makes the connection between the wristband and the integrated communication gateway module more convenient and stable, ensuring real-time data transmission and processing.

[0017] By adopting the above technical solution, the addition of electronic fence function is realized through the LoRa antenna interface, which can set the boundaries of the safe area. Once the operator exceeds the set area, the system will immediately issue an alarm. This effectively prevents operators from accidentally entering the dangerous area and improves the proactiveness of safety protection.

[0018] Optionally, the industrial control mainboard module is connected to a camera, a speaker, a microphone, and a touch screen.

[0021] By adopting the above technical solution, the industrial active electronic fence is primarily based on high-voltage pulse technology. When the fence is illegally invaded, the system generates a short, low-energy, high-voltage pulse signal. This signal is transmitted to the intruder through the fence's alloy wires, causing an electric shock effect, thereby acting as a deterrent and deterrent. At the same time, the alarm system is immediately activated, notifying security personnel to take action. The addition of the industrial active electronic fence makes the monitoring device more proactive in security protection. The electronic fence can set the boundaries of the safe area. If unauthorized objects or persons approach or enter the area, the electronic fence will immediately trigger an alarm, effectively preventing potential security risks.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-3 This application is described in further detail.

[0030] Reference Figure 1 , a confined space Internet of Things monitoring device for safety protection, including an industrial control fusion communication terminal 100, a monitoring device terminal 200 and a gas detection device 300. The industrial control fusion communication terminal 100 includes an external machine and an internal machine, which are connected wirelessly, thereby enhancing the convenience and flexibility of use. The gas detection device 300 is specifically connected to the internal machine. The gas detection device 300 includes a carbon monoxide detector and a methane gas sensor, which are used to monitor the gas concentration in the confined space in real time to ensure the safety of the working environment. When it is detected that the concentration of dangerous gases exceeds the standard, countermeasures can be taken quickly to prevent accidents. The monitoring device terminal 200 is also connected to the internal machine. The monitoring device terminal 200 is designed to be wearable on the operator's body. It is convenient to notify the operator in time in an emergency.

[0031] Reference Figure 2 The external and internal units of the industrial control converged communication terminal 100 both include an industrial control motherboard module 110, a converged communication gateway module 120, and a power management module 130. The converged communication gateway module 120 is mounted on the industrial control motherboard module 110, and the power management module 130 is electrically connected to the industrial control converged communication gateway module 120, providing stable and reliable power support and also enabling signal transmission.

[0032] The industrial control fusion communication terminal 100 can also be connected to the fusion communication base station, and the fusion communication gateway module 120 can be connected to the data center. The data center can remotely monitor the industrial control fusion communication terminal 100, thereby realizing remote and centralized control of the status of the monitoring equipment terminal 200.

[0033] Reference Figure 2 and Figure 3 The integrated communication gateway module 120 is provided with a gas LoRa antenna interface, which is used to connect to the gas detection device 300. The industrial control motherboard module 110 cooperates with the multi-functional Android program to realize the automatic control process of the monitoring device terminal 200. The Android program can be implemented through existing programs, and this solution does not include program improvements.

[0034] The fusion communication gateway module 120 is also equipped with a wristband interface, through which the wristband is connected to the fusion communication gateway module 120. It is worth mentioning that the wristband interface specifically includes a wristband LORA antenna interface, a wristband UWB antenna interface, and a wristband Bluetooth antenna interface, supporting multiple communication protocols, thereby ensuring the flexibility and reliability of data transmission.

[0035] Reference Figure 1 and Figure 3 To enhance the device's security, the monitoring device also includes an industrial active electronic fence 400, which is connected to the internal device. The converged communication gateway module 120 is equipped with a LoRa antenna interface for the electronic fence, which can be used to communicate with the industrial active electronic fence 400 and transmit security information in a timely manner.

[0036] In order to simplify the device structure and reduce costs, the gas LORA antenna interface and the electronic fence LORA antenna interface can be designed as the same interface, that is, the two share one LORA antenna interface.

[0037] In addition, the industrial control converged communication terminal 100 can also be connected to other sensing devices, such as a tool scanning terminal. Tool scanning terminals are devices specifically designed to scan and identify information such as barcodes and QR codes on tools. These devices are widely used in various fields, such as industry, logistics, and warehousing, to improve work efficiency and accuracy. The converged communication gateway module 120 is equipped with a RFID interface that can be used with tool scanning terminals to input information. This allows the entry of operator identity information, equipment information, or material status. RFID technology can be used to identify operator identity information, equipment information, or material status and record them for easier management.

[0038] Reference Figure 3 The industrial control motherboard module 110 is further connected to a camera, speaker, microphone, and touch screen. The camera can be used to monitor the working environment in real time, the speaker can be used to issue alarms or prompts, the microphone can be used to receive voice commands from the operator, and the touch screen provides an intuitive operating interface, enriching the functionality and interactivity of the device.

[0039] The implementation principle of this embodiment is as follows: the gas detection equipment 300 monitors the gas concentration in the confined space in real time and transmits the monitored data to the industrial control fusion communication terminal 100. After receiving the data, the industrial control fusion communication terminal 100 will make a judgment based on the preset safety threshold. Once the monitoring data exceeds the safety range, the industrial control fusion communication terminal 100 will immediately trigger an alarm signal, emit a loud alarm sound through the speaker, and display a clear alarm message through the touch screen. At the same time, the camera will monitor the working site in real time, and the microphone will be ready to receive the voice instructions of the operator at any time to provide timely and effective help and support. Ensure that the operator can quickly take safety measures through the internal machine, and external personnel can also monitor the safety of the operator and the internal site situation in real time through the external machine. This comprehensive safety protection function greatly improves the safety of operators in confined spaces.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
