[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-3 and Figure 6 This utility model provides a technical solution: a low-power WAPI sensor, including a protective housing 1, an internally threaded post 2 fixedly connected to the lower inner wall of the housing 1, a support substrate 3 slidably connected to the internally threaded post 2, the substrate 3 being connected to the inner wall of the housing 1 by screws, a WAPI communication module 4, a WAPI sensor module 5, a microcontroller module 6 and a power management module 7 connected above the substrate 3, a protective hollow cover 8 slidably connected above the housing 1, a fastening mechanism 9 for fastening is provided inside the hollow cover 8, and an antenna 10 for transmitting signals is connected to the back of the housing 1.

[0025] The power management module 7 of this low-power WAPI sensor can automatically adjust the supply voltage and current according to the working status of the WAPI sensor module 5. When the power management module 7 is in standby mode, it reduces the supply voltage to reduce power consumption. During data acquisition and transmission, it provides a stable power supply. At the same time, the power management module 7 has a low-power sleep mode and a fast wake-up function, which can switch from sleep mode to working mode in a short time.

[0026] Both the microcontroller module 6 and the WAPI communication module 4 are low-power models. The microcontroller module 6 has a low-power operating mode and rich peripheral interfaces, which can reduce power consumption while meeting the data processing requirements of the WAPI sensor module 5. The WAPI communication module 4 adopts advanced low-power design technology to reduce power consumption when transmitting and receiving signals while ensuring communication performance.

[0027] The WAPI sensor module 5 uses low-power sensor elements and has a reasonable sampling frequency. For some slowly changing physical quantities, the sampling frequency is appropriately reduced to reduce the number of data acquisitions, thereby reducing power consumption. At the same time, the WAPI sensor module 5 has automatic sleep and wake-up functions. When no significant change is detected in the environmental parameters, it automatically enters sleep mode.

[0028] An intelligent wake-up mechanism is added. By monitoring and analyzing environmental parameters, it is determined whether the WAPI sensor module 5 needs to be woken up for data acquisition and transmission. When the environmental parameters exceed the preset threshold range, the WAPI sensor module 5 is automatically woken up. When the environmental parameters are within the normal range and change slowly, the WAPI sensor module 5 is kept in sleep mode.

[0029] exist Figures 1-3 In the middle, slots 11 for limiting the connector 12 are provided on the inner wall of the outer shell 1 and below the hollow cover 8. The connector 12 for wiring is slidably connected in the slot 11. A pin header 13 for docking is connected to one side of the connector 12. A pin seat 14 for wiring is inserted below the pin header 13. A connecting plate 15 for support is connected to the bottom of the pin seat 14. The connecting plate 15 is connected to the base plate 3.

[0030] When the connector 12 of this low-power WAPI sensor is damaged, the hollow cover 8 is removed, and then the connector 12 is pulled up directly to pull it out of the slot 11. At the same time, the pin header 13 is pulled out of the needle seat 14. The connector 12 that needs to be replaced is inserted into the slot 11. At this time, the pin header 13 is inserted into the needle seat 14. No soldering is required, and the connector 12 can be quickly replaced.

[0031] exist Figure 4 and Figure 5 In the middle, the fastening mechanism 9 includes a threaded rod 901 that passes through and is rotatably connected to the inner wall of the hollow cover 8. The threaded rod 901 is threadedly connected to the inner threaded post 2, and a driven bevel gear 902 for driving the threaded rod 901 to rotate is connected to the outer side of the threaded rod 901. A double-headed bevel gear 903 for driving the driven bevel gear 902 to rotate is meshed on the outer side of the driven bevel gear 902. The double-headed bevel gear 903 is rotatably connected to the inner wall of the hollow cover 8 through a bracket.

[0032] The low-power WAPI sensor has a double-headed bevel gear 903 consisting of a bevel gear mounted on each end of the shaft. The sealing gasket is placed on the outer shell 1, and the hollow cover 8 is inserted into the outer shell 1. The sealing gasket is then pressed down, at which point the end of the threaded rod 901 extends into the internal threaded post 2.

[0033] exist Figure 4 and Figure 5 In the middle, the other end of the double-headed bevel gear 903 is meshed with a drive bevel gear 904 for driving the double-headed bevel gear 903 to rotate. An internal hexagonal rod 905 is connected through the drive bevel gear 904 and is rotatably connected to the inner wall of the hollow cover 8.

[0034] This low-power WAPI sensor uses a hex screwdriver to rotate the internal hexagonal rod 905, which drives the active bevel gear 904 to rotate. The active bevel gear 904 drives the double-headed bevel gear 903 to drive the driven bevel gear 902 to rotate. The driven bevel gear 902 drives the threaded rod 901 to rotate in the internal threaded column 2, thereby pulling the hollow cover 8 downward to squeeze the sealing gasket, and installing the hollow cover 8 and the outer shell 1 together, improving the efficiency of disassembly and assembly, and facilitating the replacement of the connector 12.
