[0001] The present application relates to an insect control device and method, in particular to an intelligent termite control system and method based on a Hall sensor. BACKGROUND

[0002] Termite control is an important problem in the fields of construction, agriculture, forestry, etc., and the existing technology has obvious deficiencies in monitoring accuracy, environmental adaptability, functional integrity and long-term deployment capability.

[0003] Traditional termite detection devices rely on mechanical structures (such as deep hole design in bait strips) or changes in the state of conductive materials (such as metal wire breakage) to judge termite activity, which is greatly affected by humid, acidic and other harsh environments, has a high false alarm rate and unstable performance. Although some technologies such as patent CN104982399A optimize the problem of easy oxidation and breakage of metal wires by triggering detection switches through carrier descent, they still belong to physical contact detection and lack environmental data support, making it impossible to achieve accurate monitoring.

[0004] Existing devices are relatively single in function, most of which only have monitoring function and lack effective killing mechanism, making it difficult to form a monitoring and killing integrated control system. At the same time, in terms of data transmission and analysis, the existing technology mostly uses traditional communication methods, which has the problems of high power consumption, unstable data transmission, etc., and lacks monitoring and dynamic compensation of signal strength, affecting data accuracy and alarm reliability.

[0005] In summary, there is an urgent need for a termite control system and method that integrates accurate monitoring, intelligent analysis, automatic killing, and has strong environmental adaptability and low power consumption. SUMMARY

[0012] Further, the waterproof and corrosion-resistant material of the shell is polytetrafluoroethylene, the diameter of the termite entry hole is 3-5mm, and the hole spacing is uniformly distributed.

[0013] Further, the degradable support piece is made of starch-based biodegradable material, and the thickness is 0.3-0.8mm, which can be naturally degraded in soil environment for 3-6 months.

[0014] Further, the magnetic steel is a neodymium-iron-boron strong magnet, the surface is plated with nickel to prevent corrosion, and the magnetic field strength is in the range of 500-1000 gauss.

[0015] Further, the Hall sensor is selected as a linear Hall sensor, which has a detection accuracy of ±1 Gauss, a working temperature range of -40℃-85℃, and can adapt to different environmental temperature changes.

DETAILED DESCRIPTION

[0034] The present application will be further described in detail below with reference to the accompanying drawings.

[0035] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings, it should be understood that the preferred embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0036] I. System structure implementation:

[0037] As shown in Figure 1 , Figure 2 and Figure 3 , the intelligent termite control system based on Hall sensor of the present embodiment comprises a shell 1, a bait bin 3, an electronic bin 8 and a cloud platform 16.

[0038] The shell 1 is made of polytetrafluoroethylene material, which has good waterproof and corrosion resistance, and the surface is uniformly distributed with termite entry holes 2 with a diameter of 4 mm, which facilitates the entry of termites.

[0039] The bait bin 3 is installed inside the shell 1, and the bottom is provided with a starch-based degradable support sheet 4 with a thickness of 0.5 mm, and the support sheet is placed with bait 5, and the bait 5 is added with a wood cellulose and pheromone compound (proportion 10:1) and a microcapsule pesticide coated with fluometuron particles accounting for 5% of the total mass of the bait. A magnetic steel placement bin 6 is provided above the bait 5, and a nickel-plated neodymium iron boron magnetic steel 7 is placed in the bin, with a magnetic field strength of 800 gauss, and the magnetic steel placement bin 6 is communicated with the bait bin 3.

[0040] The integrated circuit board 15 in the electronic bin 8 is integrated with a Hall sensor 9, a temperature and humidity sensor 10, a control unit 11, a communication module 12, a power management module 13, a signal strength detection and adjustment module 14 and an alarm module. The Hall sensor 9 is selected to be linear, with a detection accuracy of ±1 gauss, and is located above the falling path of the magnetic steel 7; the temperature and humidity sensor 10 is of SHT30 type, which can monitor the environmental temperature and humidity in real time; the control unit 11 is integrated with MSP430 series low-power MCU; the communication module 12 adopts QuecTel BG95-M3 CAT1 module; the power management module 13 is powered by a 3.7V lithium battery and cooperates with a 5V solar charging panel; the signal strength detection and adjustment module 14 is connected with the control unit 11, and has a built-in real-time compensation algorithm; the alarm module adopts a buzzer.

[0041] II. Working process implementation:

[0042] The termite control is carried out according to the following steps:

[0043] Step 1: Install the system in the target monitoring area such as the periphery of a building foundation, farmland or forest land, etc. Ensure that the shell 1 is partially buried in the soil, and the termite entry hole 2 faces the inside of the soil. After the system is started, each module begins to work. The temperature and humidity sensor 10 collects real-time environmental temperature and humidity data. The Hall sensor 9 continuously monitors the magnetic field state of the magnetic steel 7. The power management module 13 performs dynamic power consumption adjustment, and controls the system to enter low-power mode when there is no data transmission.

[0044] Step 2: When termites are attracted by the pheromones in the bait 5, they enter the shell 1 through the termite entry hole 2 and eat the bait 5. As the bait decreases, the degradable support sheet 4 gradually damages, and the magnetic steel 7 falls down along the magnetic steel placement bin 6 due to gravity. The Hall sensor 9 detects that the magnetic field strength gradually weakens. When the magnetic field strength changes by more than 50 gauss, a trigger signal is generated and sent to the control unit 11.

[0045] Step 3: The control unit 11 receives and processes the trigger signal, integrates the environmental data collected by the temperature and humidity sensor 10 and the signal strength data monitored by the signal strength detection adjustment module 14, and controls the communication module 12 to immediately upload these data to the cloud platform 16 through the MQTT protocol in the event trigger mode. If no significant magnetic field change is detected within the preset period (3 days in this embodiment), upload the data once every preset period.

[0046] Step 4: The cloud platform 16 analyzes the received data, compares the real-time temperature and humidity data with the suitable temperature and humidity range for termite activity (25-30℃, relative humidity 70%-90%), and judges the activity level of termite activity based on the magnetic field strength change trend. For example, when the temperature and humidity are in the suitable range and the magnetic field strength continues to weaken, it indicates that the termite activity is active.

[0047] Step 5: If the cloud platform 16 judges that the termite activity reaches the predetermined threshold (in this embodiment, the cumulative change of the magnetic field strength exceeds 200 gauss), the control unit 11 starts the alarm module, the buzzer emits an alarm sound, and the intelligent push module sends the alarm information (including the monitoring location, termite activity level, environmental data, etc.) to the user's mobile phone APP through the cloud platform 16. In the process of eating bait 5, termites will ingest microcapsule drugs, and microcapsules will rupture and release fipronil in the termite body, achieving automatic killing. The habit of termites licking each other will spread the drug in the group, improving the killing effect.

[0048] According to the test, the false alarm rate of the system in the soil with humidity >90% is less than 1%, the endurance time is 36 months, and the system can effectively achieve accurate monitoring and efficient killing of termites.

[0049] The above merely illustrates the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which are made by using the content of the present application specification and drawings, are also included in the patent protection scope of the present application.
