The first circuit board 15 is located inside the fixed inner ring 13 and has a power supply and signal circuit modulation unit integrated on the first circuit board 15. The MCU data processing unit 16 is integrated on the first circuit board 15. The mounting plate 17 is located above the first circuit board 15 and is threadedly connected with the first circuit board 15 through the first connecting screw 18. The first circuit board 15 is threadedly connected with the base 11 through the first connecting screw 18. The display and remote control module 19 is fixedly arranged above the mounting plate 17. The top cover 110 is located above the display and remote control module 19 and is threadedly connected with the outside of the fixed inner ring 13 by inserting the connecting groove 14 at the bottom of the top cover 110. The connecting piece 111 is fixedly arranged on the base 11.

[0029] Therefore, the operator installs the monitoring device on the mounting part through the connecting piece 111.

[0030] As shown in Figures 5-6As shown, in a preferred embodiment, the connecting mechanism 2 includes a connecting seat 21, a through hole 23, a fixing frame 24, a sliding limiting groove 25, a bidirectional lead screw 26, a sliding sleeve 28, a plug rod 29, a fixing sleeve 22, an adjusting handle 27, and a positioning groove 210. The connecting seat 21 is fixedly connected to the side of the base 11, and a groove is formed on the surface of the connecting seat 21 away from the base 11. The through hole 23 is formed on the surface of the connecting seat 21, penetrates the connecting seat 21, and communicates with the groove. The fixing frame 24 is fixedly connected to the connecting seat 21, and the sliding... The limiting groove 25 is formed on the inner wall of the bottom of the fixed frame 24. One end of the bidirectional screw 26 is rotatably connected to the sliding limiting groove 25, and the other end passes through the fixed frame 24. The sliding sleeve 28 is threaded onto both ends of the bidirectional screw 26 and is located inside the fixed frame 24. The insertion rod 29 is fixedly connected to the sliding sleeve 28. The insertion rod 29, the through hole 23 and the insertion hole 32 are matched in size and position. The fixed sleeve 22 is fixedly connected to the outside of the connecting seat 21. The adjusting handle 27 is fixedly connected to one end of the bidirectional screw 26. The positioning groove 210 is formed on the inner wall of the connecting seat 21.

[0031] like Figures 7-8 As shown in this disclosure, the sensor module 3 includes a mounting base 31, a socket 32, a second circuit board 33, a signal amplifier 34, a top plate 35, a second connecting screw 36, a carbon monoxide sensor 37, a positioning rod 38, and a sleeve cover 39. The socket 32 ​​is located on both sides of the mounting base 31. The second circuit board 33 is fixedly connected to the inside of the mounting base 31. The signal amplifier 34 is integrated on the second circuit board 33. The top plate 35 is located above the signal amplifier 34.

[0032] Therefore, when the carbon monoxide sensor 37 is damaged or reaches the end of its service life, the operator rotates the adjusting screw to drive the bidirectional lead screw 26 to rotate. The rotation of the bidirectional lead screw 26 causes the two sliding sleeves 28 to move away from each other, thereby moving the insertion rod 29 until it is completely disengaged from the through hole 23 and the insertion hole 32. At this time, the operator rotates the sleeve cover 39 to separate it from the fixed sleeve 22, and then removes the old carbon monoxide sensor 37 module 3 from the fixed sleeve 22. Then, the new sensor module 3 is placed inside the fixed sleeve 22, and the positioning rod 38 is accurately inserted into the positioning groove 210. Then, the operator rotates the adjusting handle 27 again to drive the bidirectional lead screw 26 to rotate in the opposite direction. The bidirectional lead screw 26 causes the two sliding sleeves 28 to move closer to each other until the insertion rod 29 is inserted into the through hole 23 and the insertion hole 32 again. At this time, the operator reconnects the sleeve cover 39 to the fixed sleeve 22 with threads to complete the replacement of the sensor module 3.

[0033] The carbon monoxide gas monitoring device, in use, when carbon monoxide gas leakage occurs, the carbon monoxide sensor 37 installed in the monitoring device on the site of the protected area converts the concentration parameter of the leaked flammable gas into an electrical signal, which is judged by the MCU data processing unit 16, and then after data processing by the power supply and signal modulation circuit unit, the processed data is superimposed on the power supply, the signal is transmitted to the controller connected to the detector, and the controller monitoring device makes a flammable gas concentration overrun alarm judgment, if the concentration exceeds the alarm set value, the monitoring device sends an alarm command to make the carbon monoxide detector alarm, realizing centralized management of the detector and two-wire low-cost wiring, the carbon monoxide detector can also be separated from the controller and directly powered to realize independent alarm, using power modulation technology and pulse power detection technology, realizing real-time processing and transmission of the carrier communication signal on the power line, which not only ensures the reliability of wired transmission, but also reduces the cost of traditional four-wire wiring.

[0034] The utility model has been described above in conjunction with the drawings, and obviously, the specific implementation of the utility model is not limited by the above method, as long as the method concept and technical scheme of the utility model are adopted for non-essential improvement or the concept and technical scheme of the utility model are directly applied to other occasions without improvement, which are all within the protection scope of the utility model.
