Description

Technical Field

[0001] This utility model relates to a door lock system, specifically an intelligent door lock system. Background Technology

[0002] Grain storage facilities store large quantities of grain. During storage, gases such as phosphine, nitrogen, carbon dioxide, and sulfuryl fluoride are used to control pests. Phosphine and sulfuryl fluoride are highly toxic gases, and high concentrations of carbon dioxide and nitrogen create environments with low oxygen levels. Therefore, real-time online monitoring of gases including oxygen, carbon dioxide, nitrogen, and phosphine is necessary to ensure that the levels are sufficient to effectively kill pests. Furthermore, the composition and concentration of gases must be tested before each entry into the warehouse to ensure personnel safety.

[0003] In existing grain storage enterprises, the concentration of certain gases inside the warehouses may exceed or fall below standards. Most enterprises lack real-time gas detection devices in their warehouses. In actual production and operation, only portable gas detectors are used for temporary spot checks. Due to the aforementioned limitations of these devices, sensors struggle to detect such anomalies in a timely manner. This delay could pose potential safety risks to personnel entering the grain warehouse because the true gas levels are not known beforehand. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent door lock system that allows multiple gas sensors to be extended to different locations within the warehouse to detect the concentrations of gases such as oxygen, carbon dioxide, nitrogen, sulfuryl fluoride, and phosphine. The gas concentration values ​​at different locations are simultaneously displayed on a screen and a large office status display screen, enabling personnel to have a comprehensive understanding of the gas concentration values ​​at different locations within the warehouse. This ensures the safety of personnel each time they enter the warehouse and facilitates early warning and handling of accidents, thereby improving the safety of the warehouse environment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent door lock system, including a warehouse wall and a door lock mechanism and a detection mechanism installed on the warehouse wall.

The mounting platform 31 is fixed to the lower end face of the top wall 12. A sliding groove 321 is provided on the lower end face of the fixing frame 32. Multiple reinforcing seats 322 are fixed in the sliding groove 321. A servo motor 33 is fixed on the fixing frame 32. A lead screw 34 is fixedly connected to the output end of the servo motor 33. The lead screw 34 is installed on the multiple reinforcing seats 322, so that the multiple reinforcing seats 322 support the lead screw 34. To prevent the lead screw 34 from bending or shaking and to ensure its stability during operation, multiple sliders 35 are installed on the lead screw 34. Gas detection components 36 are installed below each slider 35. The gas detection components 36 are connected to the access control host 23. A protective shell 37 is fixed to the outside of the servo motor 33 and is fixed to the fixed frame 32, so that the protective shell 37 can protect the servo motor 33. Both the servo motor 33 and the protective shell 37 are located on the outside of the warehouse.

[0028] Please see Figure 4 The detection mechanism 3 also includes a guide assembly 39, which includes multiple wiring boards 391. Both ends of each wiring board 391 are connected to the side wall 11 and the slider 35. The space above the wiring board 391 is used for wiring of the gas detection assembly 36. The guide assembly 39 also includes two guide rods 392. The multiple wiring boards 391 are slidably mounted on the two guide rods 392. The two guide rods 392 are respectively fixed to the inner side of the two edge brackets 393. The two edge brackets 393 are fixed to the upper end face of the inner support plate 13.

[0029] Please see Figure 5The gas detection component 36 includes a fixing plate 361 and a battery 362 fixed on the fixing plate 361. The fixing plate 361 is fixed to the lower end face of the slider 35, and a carbon dioxide sensor 363, an oxygen sensor 364, a nitrogen sensor 365, a phosphine sensor 366, and an infrared sensor 367 are fixed to the end of the fixing plate 361 away from the battery 362. In this embodiment, the carbon dioxide sensor 363 is model ABH105, the oxygen sensor 364 is model QL132, and the nitrogen sensor 367 is model QL132. The gas sensor 365 is model number SN-300*-N2*-*-*, the phosphine sensor 366 is model number SN-3002-PH3-*, and the infrared sensor 367 is model number 7X-HF-10. The infrared sensor 367 is used to detect the concentration of thiocyanate fluoride. Two slide rails 38 are fixed on the lower end face of the mounting platform 31. Both ends of each slider 35 are set on the two slide rails 38, so that the slider 35 can slide with the two slide rails 38, ensuring the stability of the slider 35 when sliding.

[0030] Please see Figure 6 The access control host 23 of the door lock mechanism 2 is connected to the server 5. The server 5 has WIFI function, and it is connected to the office status display screen 6, computer monitor 7 and smart terminal 8 through WIFI function. The access control host 23 of the door lock mechanism 2 is connected to the office status display screen 6, and can display the concentration of various gases on the office status display screen 6. The working principle of the access control host 23 and the display screen 22 is existing technology, and will not be described in detail here.

[0031] Please refer to the following: Figures 1 to 6 In the operation of this utility model, multiple sensors on the gas detection component 36 monitor oxygen, carbon dioxide, nitrogen, sulfuryl fluoride, and phosphine gases in the chamber in real time. During the monitoring process, the servo motor 33 is controlled by personnel to drive the lead screw 34, which in turn causes multiple sliders 35 to move multiple sets of gas detection components 36 within the chamber (simultaneously, multiple wiring boards 391 slide on guide rods 392 to ensure the stability of the wiring boards 391 and their wires). This allows for the monitoring of gas concentration values ​​at various locations within the chamber, resulting in a wider monitoring range and more comprehensive and reliable monitoring results. Multiple sensors can transmit electrical signals to the access control host 23, which then sends two sets of signals. One set of signals is sent to the display screen 22 to display the gas concentration data, and the other set is sent to the office status display screen 6. Before entering the chamber, personnel undergo facial recognition on the display screen 22 (the technical principle of facial recognition is existing technology and will not be elaborated here). Only after confirming that the data for various gases displayed on the display screen 22 are within safe ranges can personnel enter the chamber.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
