Description

Technical Field

[0001] This application relates to the field of wireless controller technology, and in particular to a 4G IoT wireless dual-output controller. Background Technology

[0002] In industries such as chemical, oil, and natural gas, combustible gas detectors are required. When a detector detects that the gas concentration exceeds the standard, immediate measures must be taken, such as shutting off solenoid valves. However, the working environments in these industries are too complex, and the equipment is usually arranged closely together, leaving limited space for the maintenance of the wiring system. This makes maintaining and replacing wires and cables more difficult, failing to meet the requirements for the use of combustible gas detectors. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this application is to provide a 4G IoT wireless dual-output controller to solve the technical problems mentioned in the background art.

[0004] The above-mentioned objective of this application is achieved through the following technical solution: a 4G Internet of Things wireless dual-output controller, including a wireless controller for connecting a solenoid valve;

[0005] The wireless control is connected to a combustible gas detector and an alarm host that are installed in conjunction with the work site. The alarm host is wirelessly connected to the wireless controller and the combustible gas detector, and the wireless controller is wired to the solenoid valve.

[0006] By adopting the above technical solution, combustible gas detectors can be installed in various locations within the work site. The solenoid valve is used to cut off or shut off the flow of fluid gas in the pipeline. When the combustible gas detector detects that the gas concentration exceeds the standard in a hazardous environment, it immediately sends a 4G signal to the alarm host. Upon receiving this signal, the alarm host sends an alarm signal to the wireless controller via the 4G IoT module. The wireless controller then sends a closing signal to the solenoid valve, thereby activating the solenoid valve to cut off the gas supply. This application employs multiple wireless control methods for the combustible gas detector, eliminating the need for wiring and making detector placement easier.

[0007] Furthermore, an exhaust fan is also connected to the wireless controller.

[0008] By adopting the above technical solution, while the wireless controller sends a signal to the solenoid valve, it also sends a start signal to the exhaust fan to discharge hazardous gases and reduce the risk factor in the environment.

[0009] Furthermore, an alarm device for alerting staff is fixedly installed on the upper part of the alarm host.

[0010] By adopting the above technical solution, when a combustible gas detector detects an excessive concentration of hazardous gas and triggers an alarm, it quickly attracts the attention of personnel, ensuring they are aware of the danger and can take necessary emergency measures immediately. This instant warning mechanism significantly shortens the time from detection to response, improves response speed, helps reduce potential damage from gas leaks, and protects the safety of personnel and equipment.

[0011] Furthermore, the wireless controller includes a bottom shell, a top cover, and an antenna on the bottom shell. A circuit board is installed in the middle of the bottom shell, and wires are fixedly installed at both ends of the circuit board. A plug is fixedly installed on one end of the wire, and the other end is connected to a solenoid valve and an exhaust fan.

[0012] By adopting the above technical solution, the wireless controller offers multiple benefits, including a compact and fully functional structure, ease of installation and maintenance, efficient data transmission and reception, flexible power connection, enhanced system security, and ease of integration and expansion. Optimizing antenna placement and performance ensures stable data transmission in complex environments. The plug design facilitates convenient power connection, while direct connection of the circuit board to solenoid valves and exhaust fans enables precise control of these devices. This design not only improves the overall system performance and stability but also significantly enhances security, making the wireless controller widely applicable in fields such as industrial safety and environmental monitoring, providing users with an efficient, reliable, and secure solution.

[0013] Furthermore, a fixing screw ring is provided between the upper cover and the bottom shell, the fixing screw ring has a positioning hole, and threaded holes are provided on the upper cover and the bottom shell. The threaded hole of the upper cover is threaded with a fixing screw for fixing the upper cover and the bottom shell.

[0014] By adopting the above technical solutions, the structural stability is significantly enhanced, the physical connections are strengthened, reducing the risk of loosening due to vibration or external impact, and the precise positioning of the threaded holes ensures accurate alignment of each component, improving overall stability. Installation and maintenance convenience is greatly improved; the modular design makes the installation and disassembly of the wireless controller easier, facilitating quick replacement or repair of internal components. The positioning holes also allow for quick alignment of the top cover and bottom shell during installation, improving installation efficiency. Electromagnetic compatibility (EMC) is optimized; the robust structure helps reduce electromagnetic interference between the internal circuit board and the external environment, improving signal transmission stability and significantly enhancing anti-interference capabilities. Durability and reliability are significantly improved, with enhanced long-term stability reducing the risk of failure due to loosening.

[0015] Furthermore, the bottom of the antenna is connected to an antenna connector, and the bottom of the antenna connector is provided with an IPEX wire that is fixedly connected to the antenna. The antenna connector and the antenna are snapped together, and the antenna connector and the bottom shell are threaded together.

[0016] By adopting the above technical solution, further optimization of the antenna connection structure is achieved by connecting an antenna connector at the bottom of the antenna and fixing the IPEX cable to the antenna. This solution also enables the antenna connector to snap onto the antenna and to be threaded onto the bottom shell. This technical solution brings several significant benefits: the antenna connection stability is significantly enhanced. The dual fixing method of threaded connection and snap-fit ​​ensures the antenna is physically securely installed, effectively preventing loosening or detachment due to vibration or external force. At the same time, the fixed design of the IPEX cable ensures the stability of signal transmission and avoids poor contact or signal attenuation caused by cable shaking. The ease of installation and maintenance is greatly improved. The modular antenna connection design makes the installation and disassembly of the antenna more convenient and faster.

[0017] Furthermore, the wire is evenly provided with fixing screw sleeves, the inner side of the fixing screw sleeves is fixedly provided with a damping layer, and the fixing screw sleeves are threadedly connected to the bottom shell.

[0018] By adopting the above technical solution, the threaded connection between the fixing screw sleeve and the bottom shell ensures the wires are firmly fixed inside the controller, preventing them from loosening or falling off due to vibration or external force. The fixing screw sleeves are evenly distributed on the wires, making the wire fixation more uniform and reducing the risk of wire damage caused by uneven local stress. The damping layer inside the fixing screw sleeve effectively absorbs and reduces vibrations generated by the wires during operation, reducing noise and wear caused by vibration.

[0019] In summary, this application includes the following beneficial technical effects: When the combustible gas detector detects that the concentration of hazardous gas exceeds the standard, it will immediately send a concentration exceedance signal to the alarm host. After receiving the signal, the alarm host sends the alarm signal to the wireless controller through the 4G IoT module, and then the wireless controller sends a closing signal to the solenoid valve, activating the solenoid valve to cut off the gas supply. This application adopts multiple wireless control methods for combustible gas detectors, eliminating the need for wiring to the combustible gas detectors, facilitating detector placement. Its beneficial effects are reflected in the ease of installation; the absence of wiring allows the detectors to be flexibly placed in various locations in the work area, without wiring restrictions, and can be rationally laid out according to actual needs, improving the comprehensiveness and accuracy of monitoring, simplifying the installation process, and reducing installation costs and time. In terms of system stability and reliability, the wireless connection between the alarm host, the wireless controller, and the combustible gas detector... Through meticulous design and optimization, the system ensures stable and reliable signal transmission, guaranteeing accurate transmission of alarm and control signals even in complex working environments. The system can also quickly respond and cut off the gas supply. For ease of maintenance, modular design facilitates installation, disassembly, and repair; faulty components can be quickly replaced, reducing downtime and improving system availability. Remote monitoring and management are possible via a 4G IoT module, allowing staff to understand the system's operating status anytime, anywhere, promptly identify and resolve problems, and improve maintenance efficiency. The controller boasts excellent scalability and compatibility, easily integrating with other systems or equipment. It supports multiple wireless communication protocols and is compatible with different types of combustible gas detectors and solenoid valves, meeting diverse user needs. Furthermore, it reduces safety risks by effectively mitigating the safety risks associated with combustible gas leaks through timely gas supply cutoff, protecting personnel and equipment safety.
