[0003] The grain condition measurement and control system mainly focuses on temperature data monitoring, but ignores humidity, carbon dioxide concentration, and other parameters that also have important effects on the grain storage environment; this results in the system being unable to provide comprehensive and accurate monitoring data for grain storage, thereby limiting the degree of refinement of grain storage management to some extent; for example: the reasons for the increase in grain temperature are not limited to mold and pests; high moisture content mixed stacking and other reasons can also cause temperature changes, and single temperature detection may lead to misjudgment; secondly, single temperature detection provides limited grain parameters and cannot predict future grain condition problems; for example: grain condensation caused by sudden temperature drop needs to be judged in combination with temperature and humidity, and insect pests and mold need to be judged in combination with temperature and carbon dioxide content.

[0004] The existing sensor lacks real-time monitoring of environmental parameters such as humidity and carbon dioxide, which can easily lead to inaccurate control of the grain storage environment, increasing the risk of grain moisture, mold, insect pests, and other risks, thereby affecting the quality and safety of the grain. Therefore, a new type of insect and mold early warning sensor is needed to realize comprehensive monitoring of the grain storage environment and provide a more scientific and reliable basis for grain storage management.

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0019] Please refer to Figures 1 to 4 The utility model provides a technical scheme: a grain insect and mold early warning sensor, comprising: a shell 1, the inside of the shell 1 is provided with; an interface unit, a protection unit, a sensor unit and a control unit, the protection unit is connected to the interface unit, the control unit is connected to the protection unit, the sensor unit is connected to the control unit and the protection unit respectively, and the control unit communicates with external equipment through the interface unit.

[0020] The control unit comprises: a voltage conversion module and a main controller module 2, the voltage conversion module is connected with the protection unit, and the main controller module 2 is connected with the voltage conversion module; the sensor unit comprises: a capacitive sensor, a temperature and humidity sensor and a carbon dioxide sensor; wherein the capacitive sensor is electrically connected with the protection unit, and the temperature and humidity sensor and the carbon dioxide sensor are electrically connected with the voltage conversion module.

[0021] It should be noted that when the grain mold early warning sensor is working, the external power supply is connected through the interface unit to supply power for the control unit and the sensor unit. The protection unit is connected to the interface unit to protect the subsequent sensor unit and the control unit from external interference and damage to the sensor unit. The sensor unit transmits the collected environmental information to the control unit. The voltage conversion module transmits the processed input voltage to the main controller module 2, and the main controller module 2 receives data from the capacitive sensor, the temperature and humidity sensor, and the carbon dioxide sensor of the sensor unit, calculates and analyzes these data, realizes comprehensive monitoring of key parameters of the grain storage environment according to the integrated temperature, humidity, and carbon dioxide sensor data collected by the carbon dioxide sensor, and finally sends the processed information to the external device through the communication interface module of the interface unit, completes the communication between the control unit and the external device, and provides comprehensive and accurate data support and risk early warning for grain storage management.

[0022] The capacitive sensor is not directly connected to the voltage conversion module. The capacitive sensor in the traditional grain sensor is directly connected to the voltage conversion module, which makes it difficult to upgrade and modify the subsequent circuit. Because the capacitive sensor is closely coupled with the voltage conversion, when adding new sensors or adjusting functions, the entire circuit needs to be changed. The capacitive sensor used in the device is not connected to the voltage conversion module, and the modular design idea is adopted to indirectly connect between the interface board or the signal conditioning circuit, which can easily replace, add or reduce sensors, enhance the system expansion and compatibility, and ensure seamless cooperation between sensors. At the same time, it reserves sufficient interfaces for possible new monitoring technologies in the future, so that the entire system can continuously adapt to the technical development and actual demand changes in the field of grain storage management, showing high technical innovation and practicality, and facilitating flexible optimization of system architecture according to actual grain monitoring needs.

[0023] In some examples, the interface unit includes a communication interface module and a power interface module. The communication interface module is used to transmit data detected by the capacitive sensor, the temperature and humidity sensor, and the carbon dioxide sensor to an external device. The power interface module is used to connect an external power supply to provide power support for the protection unit, the control unit, and the sensor unit.

[0024] It needs to be explained that when the sensor unit starts to work, the power interface module first plays a role, it connects the external power supply, introduces the electric energy, provides stable power support for the protection unit, the control unit and the sensor unit, ensures that each unit can operate normally. In terms of data transmission, the communication interface module is responsible for transmitting the data detected by the capacitive sensor, the temperature and humidity sensor and the carbon dioxide sensor to the external equipment, which establishes a data communication bridge between the internal sensor unit and the external equipment, so that the external equipment can obtain the various data about the grain storage environment collected by the sensor in time, thereby providing a data basis for subsequent data analysis, processing and grain storage management decision-making.

[0025] In some examples, the protection unit includes: the protection unit includes: an electrostatic protection module and a surge protection module, the electrostatic protection module and the surge protection module are used to protect the capacitive sensor, the temperature and humidity sensor and the carbon dioxide sensor from external interference.

[0026] As Figure 4 shown, Figure 4 The system principle diagram of the utility model is shown, in Figure 4 which, the solid connection arrow is the circuit connection relationship, and the dashed arrow is the data signal connection relationship, it needs to be explained that in the working process of the grain insect and mold early warning sensor, the electrostatic protection module and the surge protection module continuously play a role. When there is static electricity or surge phenomenon in the external environment, the electrostatic protection module will first process the static electricity that may affect the normal work of the capacitive sensor, the temperature and humidity sensor and the carbon dioxide sensor, guide the static electricity to a safe path and release it, avoid the damage to the sensor caused by the accumulation of static electricity. At the same time, the surge protection module prevents the surge current or voltage that may appear, once the abnormal surge signal is detected, the protection mechanism will be started quickly, such as using voltage limiting, current limiting and other ways, to prevent the impact of surge on the sensor, so as to ensure that the capacitive sensor, the temperature and humidity sensor and the carbon dioxide sensor are always in a stable working state, are not affected by external interference, and accurately collect the related data in the grain storage environment.

[0027] In some examples, the main controller judges whether the grain exists insect damage and mold risk according to the data collected by the capacitive sensor, the temperature and humidity sensor and the carbon dioxide sensor, and sends the information to the external equipment through the communication interface module.

[0028] It should be noted that during the operation of the grain insect and mold early warning sensor, the capacitive sensor, the temperature and humidity sensor, and the carbon dioxide sensor continuously collect data of the grain storage environment. These data are transmitted to the main controller module 2, which uses the built-in algorithm and data analysis model to comprehensively analyze and process the data from different sensors. The built-in algorithm and data analysis function is a well-known technology in the art and is not described in detail here. The main controller module 2 will compare the relevant data collected by the capacitive sensor, the temperature and humidity information provided by the temperature and humidity sensor, and the carbon dioxide concentration data detected by the carbon dioxide sensor according to the preset judgment standard and logic to determine whether the grain is at risk of insect and mold damage. Once the risk judgment is completed, the main controller module 2 will send the processing results to the external device through the communication interface module, so that the external device can timely obtain the risk status information of the grain storage environment, so that relevant personnel can take appropriate measures to ensure the safety of grain storage.

[0029] In some examples, the capacitive sensor, the temperature and humidity sensor, and the carbon dioxide sensor are signal connected with the main controller module 2, and the main controller module 2 is signal connected with the communication interface module through the protection unit.

[0030] It should be noted that when the grain insect and mold early warning sensor is working, the capacitive sensor, the temperature and humidity sensor, and the carbon dioxide sensor monitor the relevant data of the grain storage environment in real time, and transmit the collected data to the main controller module 2 in the form of signals. After receiving these signals, the main controller module 2 processes and analyzes the data. After processing is completed, when the information generated by the main controller module 2 needs to be transmitted externally, the signal first passes through the protection unit, which transmits the signal to the communication interface module under the condition of ensuring that the signal is not disturbed externally. The main controller module 2 determines the state change of the grain storage environment according to the temperature and humidity data, the carbon dioxide concentration data, and the relevant data obtained by the capacitive sensor. After accurate calculation and processing by the main controller module 2, the processing results form transmittable information, which is then transmitted to the external device through the communication interface module, realizing a complete transmission link from the sensor to the main controller and then to the external device, so that the external device can timely obtain accurate evaluation and potential insect and mold risk warning information about the grain storage environment, providing effective data basis for grain storage management, so as to take appropriate control measures to ensure the quality and safety of grain.
