technical field

The invention relates to the technical field of flexible sensing, in particular to an anti-shaking medicine box with a temperature and pressure monitoring function.

Background technique

With the application of plant protection drones in the agricultural field, there are now drone medicine boxes with loads ranging from 5kg to 50kg on the market. The traditional medicine box has the problem of liquid medicine sloshing inside the medicine box, which will cause the vibration and imbalance of the drone and seriously affect the flight safety of the drone. Traditional medicine boxes cannot meet the needs of plant protection drones. Different pesticides have different physical and chemical properties, corresponding to different optimal spraying temperatures. According to the type of drug, controlling the temperature of the drug solution within its optimal use range can obtain better drug effect. When using drones to spray pesticides remotely, the operator needs to know the remaining amount of liquid medicine in the medicine box in real time and plan the plant protection operation plan reasonably. Installing a temperature monitoring device and a liquid level monitoring device in the drone's medicine box to monitor the temperature and balance of the liquid in real time is of great significance for efficient plant protection operations.

To realize the monitoring of liquid level and temperature, the traditional solution needs to use liquid level sensor and temperature sensor respectively. Traditional sensors are generally made of rigid materials, which are not suitable for non-planar measurements such as curved surfaces. The flexible sensor has the advantages of good deformation ability, good fit, and accurate measurement, and can well adapt to the non-planar structure inside the medicine box. It has the advantages of good fit and accurate measurement.

At present, the research of flexible sensors is mainly aimed at the measurement of a single physical parameter such as pressure, strain or temperature, and the function is relatively single. There are few studies on composite flexible sensors that can measure pressure and temperature simultaneously.

Ionic liquids are generally composed of organic cations and inorganic or organic anions. Common cations include quaternary ammonium salt ions, quaternary phosphonium salt ions, imidazolium salt ions, and pyrrole salt ions. Ionic liquids have a low melting point and good electrical conductivity and thermal conductivity. Conductivity. The high sensitivity of ionic liquid to temperature can be used to realize the measurement of temperature. Liquid metal-based resistive flexible pressure sensors have achieved pressure measurement well.

In order to simplify the structure and manufacture of the sensor. The invention proposes to use the deformability of liquid metal and the high sensitivity of ionic liquid to temperature to design a flexible temperature and pressure sensor instead of the traditional solid conductor as the sensing element. A flexible temperature and pressure sensor is used to monitor the temperature and pressure changes of the medicine liquid in the medicine box. The received liquid medicine pressure is converted into the corresponding liquid level height through signal conversion calculation, so as to realize the monitoring of the liquid medicine temperature and liquid level height in the medicine tank. In terms of specific structure, the flexible temperature and pressure sensor adopts a double-layer structure design, which can greatly simplify the structure of the sensor and reduce the difficulty of manufacturing, and the sensor has good deformability and high sensitivity to external pressure and temperature changes. . The output signal has good linearity and excellent sensing performance. In addition, the double-layer structure can effectively avoid mutual interference between temperature measurement and pressure measurement.

In order to verify the above-mentioned beneficial effects, the following comparative experiments were carried out:

Comparative test one:

Add liquid medicine to the body of the medicine box at room temperature. As the liquid level of the liquid medicine rises gradually, the pressure of the liquid medicine acting on the pressure sensing part of the flexible temperature and pressure sensor through the force transmission column also rises gradually, and the link-like liquid metal The relative resistance value of the resistor is constantly changing, and a curve of relative resistance change-pressure change is obtained, as shown in FIG. 19 . The curve shows that the pressure sensing part of the liquid metal-based flexible temperature and pressure sensor has good sensitivity and stability to the liquid pressure. The resistance signals of the pressure sensing part exhibit different intensities under different liquid pressures. The resistance value of the ring-shaped liquid metal resistor increases with the increase of pressure. The higher the liquid level, the greater the pressure of the liquid medicine, and the greater the change in the resistance value of the link-state liquid metal resistor. The conversion formula of liquid level height and liquid pressure is as follows:

P = ρgh

F=PS

Among them, P is the pressure inside the liquid, h is the height of the force transmission column from the liquid surface, ρ is the density of the liquid medicine, S is the area acting on the force transmission column, F is the pressure acting on the force transmission column . Through calibration conversion, the measured pressure signal can be converted into the corresponding liquid level height.

Comparative test two:

When the medicine box body is filled with liquid medicine, the medicine liquid in the medicine box body is heated from room temperature to 65°C, and the change curve of temperature-U-shaped ionic liquid resistance impedance is obtained, as shown in Figure 20 . The curve shows that the impedance of the U-shaped ionic liquid resistance decreases with the increase of the temperature of the liquid, because the increase in temperature will cause the ion movement speed to increase and the ionic conductivity to increase (the electrolyte impedance decreases). There is a good linear relationship between the temperature of the liquid medicine and the impedance of the ionic liquid, and the temperature of the liquid medicine in the medicine box can be monitored through the impedance change of the resistance of the U-shaped ionic liquid.

Comparative test three:

The key condition for the flexible temperature and pressure sensor to be used for liquid temperature and liquid level monitoring is that it effectively avoids crosstalk between temperature signals and pressure signals. As shown in Figure 21, under the condition that the medicine box is filled with medicine liquids of different qualities (no medicine liquid, half medicine liquid and full medicine liquid), the medicine liquid is heated from room temperature (25°C) by a heating device. ) to 60°C, measure the change trend of the impedance of the U-shaped ionic liquid resistance with temperature, and obtain the change of the impedance data of the U-shaped ionic liquid resistance with the temperature of the liquid. According to the experimental results, it is shown that the structure can effectively avoid the influence of the external pressure on the temperature measurement and ensure the accuracy of the temperature measurement.

Comparative test four:

The pressure sensing part based on liquid metal has high sensitivity to stress and strain. In order to test whether the external temperature will affect its measurement results, use a heating instrument to control the temperature of the liquid medicine, and control the liquid medicine at different temperatures (room temperature, 35°C, 45°C, 55°C, 65°C), In this way, pressure-relative resistance change curves at different temperatures are obtained, as shown in FIG. 22 . The curve shows that the present invention has no obvious difference in the test results at temperatures of 35°C, 45°C, 55°C, 65°C and room temperature. Therefore, the invention can effectively avoid the crosstalk of the temperature on the pressure signal. Ensure the accuracy of pressure data measurement.

From the above results, it can be seen that flexible temperature and pressure sensors based on liquid metals and ionic liquids have high potential. The invention has the characteristics of simultaneously measuring the temperature and pressure of the medicine liquid in the medicine box, and can effectively avoid the crosstalk between the temperature signal and the pressure signal. At the same time, it has good sensitivity, low hysteresis and durability. The temperature and height of the liquid medicine in the medicine box can be monitored with high precision and excellent long-term stability in practical applications.

The present invention aims at the phenomenon of medicinal liquid sloshing and medicinal liquid deposition in the medicine box of the traditional pesticide spraying UAV, and the traditional medicine box needs to use multiple monitoring modules (medicine box liquid level monitoring module and temperature sensing module) to realize The problem of monitoring the parameters (temperature and liquid level) of the liquid medicine in the medicine box. The invention designs the structure of the medicine box so that the medicine box has the functions of preventing liquid sloshing and liquid deposition, and uses a flexible temperature and pressure sensor, an information collection module and a host computer to monitor the parameters of the liquid medicine. The multifunctional medicine box can effectively reduce the shaking of the liquid medicine in the vertical and horizontal directions to ensure the flight safety of the plant protection drone, and at the same time, it has the function of preventing the deposition of solid medicine particles to ensure the full use of the efficacy of the pesticide. The invention is applicable to the field of medicine boxes for agricultural plant protection drones.
