Description

Technical Field

[0001] The utility model relates to the technical field of intelligent probe rods, and more specifically, to an intelligent probe rod for simultaneously detecting, displaying, and periodically transmitting data of temperature, humidity, and moisture in a grain pile. Background Technique

[0002] After the harvested and dried grains enter the storage, safe and fresh storage is a key link in national food security. Ensuring that the temperature, humidity, and moisture parameters in the grain pile are reasonable and close to the optimal values is a necessary and sufficient condition for grain storage enterprises to ensure reliable grain quality and good benefits. At the same time, it provides a reliable basis for cooling, dehumidifying, and tempering mechanical ventilation.

[0003] For the purpose of safe grain storage, the state has set up a grain condition monitoring and control system. Its main components are temperature measurement cables, temperature measurement instruments, and computer software. However, the number of temperature measurement cables is large and the cost is high. The national standard for the row and column spacing is not greater than 5 meters. Since grain particles are poor conductors of temperature, the change of the output signal of the temperature sensor in the temperature measurement cable depends on the heat conduction of grain particles to be transmitted to the temperature measurement cable one by one. Therefore, the parameters of high-temperature, high-humidity, and high-moisture grains take a long time to be transmitted to the temperature, humidity, and moisture sensors embedded in the temperature measurement cable. Even in the case of heat generation at a position far from the sensor, the temperature measurement system fails to detect it in time, resulting in accidents of local grain spoilage and causing losses to the country and enterprises.

[0004] At present, ordinary domestic probe rods can only measure temperature and cannot provide humidity and moisture indicators during the ventilation process. Moreover, during the processes of loading, unloading, and ventilation of the granary, a large amount of dust will be generated, and this dust will seriously block the surface of the humidity sensor, making it impossible to accurately measure.

[0005] Therefore, how to provide an intelligent probe rod for simultaneously detecting, displaying, and periodically transmitting data of temperature, humidity, and moisture in a grain pile, which can solve the problem of dust blocking the humidity sensor resulting in inaccurate measurement of temperature, humidity, and moisture, and then realize more delicate data acquisition, processing, and remote active transmission, and effectively discover the hidden dangers endangering the safe storage of grains in a timely manner, is an urgent problem to be solved by those skilled in the art. Content of the Utility Model

[0006] In view of this, the utility model provides an intelligent probe rod for simultaneously detecting, displaying, and periodically transmitting data of temperature, humidity, and moisture in a grain pile, which can be used flexibly and moved, quickly discover high-temperature points, and is convenient for timely processing.

[0007] To achieve the above object, the utility model provides the following technical solutions.

[0008] An intelligent probe rod for simultaneously detecting, displaying, and transmitting the temperature, humidity, and moisture of a grain pile in real-time according to a set time of the present utility model includes: a rod body and a meter head rotatably connected to the top of the rod body through a keyway. The rod body and the meter head are separately provided, so that one meter head can be connected to multiple probe rods. A temperature, humidity, and moisture sensor is embedded in the rod body for detecting the temperature, humidity, and moisture data of the grain pile. A dust-proof cover is provided at a position corresponding to the embedded temperature, humidity, and moisture sensor in the rod body to prevent dust from blocking the sensor.

[0009] Further, the rod body is made of a metal tube.

[0010] Further, the meter head rotatably connected to the top of the rod body through a keyway is a set of dual-color LED digital tubes.

[0011] Further, there is a display point above the digital tube, and below it, there are four display points that sequentially display the temperature, relative humidity, and moisture value in red, yellow, and green at different times.

[0012] Further, the window of the dust-proof cover provided at the position corresponding to the embedded temperature, humidity, and moisture sensor in the rod body is semi-circular, which is convenient for disassembling the dust-proof cover when replacing the dust-proof net.

[0013] Further, a dust-proof net is lined below the dust-proof cover, and the dust-proof net can be replaced.

[0014] Further, the dust-proof cover is tightly combined with the steel pipe and fixed by screws, and small ventilation holes are provided on its surface to facilitate the detection of relative humidity and moisture.

[0015] It can be seen from the above technical solutions that, compared with the prior art, the intelligent probe rod for simultaneously detecting, displaying, and transmitting the temperature, humidity, and moisture of a grain pile in real-time according to a set time of the present utility model, through the settings of the temperature, humidity, and moisture sensor and the dust-proof component, enables users to easily replace components at any time, and solves the long-standing problem that the sensor is blocked by dust. At the same time, users can make independent decisions on the ventilation time period and the amount of air volume according to the results of humidity and moisture detection, and achieve cooling ventilation by adopting the optimal solution, control the grain moisture to reach the optimal state, and ensure that the grain reaches the optimal quality during the grain storage process.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] An intelligent probe rod for simultaneously detecting, displaying, and transmitting the temperature, humidity, and moisture content of a grain pile in a timed manner of the present utility model includes a rod body 1 and a meter head 3 rotatably connected to the top of the rod body 1 through a key groove 2. The rod body 1 and the meter head 3 are separately provided so that one meter head 3 can be connected to multiple probe rods. The rod body 1 is embedded with a temperature, humidity, and moisture sensor for detecting the temperature, humidity, and moisture data of the grain pile. A dust-proof cover 6 is provided at a corresponding position of the rod body 1 embedded with the temperature, humidity, and moisture sensor to prevent dust from blocking the sensor.

[0022] The rod body 1 is made of a metal tube material. The metal tube has high strength and stiffness, can withstand large loads, and ensures that the rod body works stably in a complex outdoor environment. Secondly, the metal tube rod body can effectively resist wind pressure and reduce deformation or damage caused by the action of wind. Finally, the metal tube rod body is a support structure for the device, such as a wireless communication module, a temperature, humidity sensor, and a moisture sensor. [[ID=1"]]

[0023] The meter head 3 rotatably connected to the top of the rod body 1 through the key groove 2 is a set of dual-color LED digital tubes. The meter head 3 is linearly connected to the temperature, humidity, and moisture sensor. There is a display point 301 above the digital tube, and four points 302 below are sequentially used to display the temperature, relative humidity, and moisture value in red, yellow, and green in a time-sharing manner. Specifically, when displaying the temperature, it is lit in red; when displaying the relative humidity, it is lit in green and red simultaneously to produce a yellow field; when displaying the moisture, it is lit in green.

[0024] The window of the dust-proof cover 6 provided at the corresponding position of the rod body 1 embedded with the temperature, humidity, and moisture sensor is semi-circular, which is convenient for disassembling the dust-proof cover 6 when replacing the dust-proof net 7. A dust-proof net 7 is lined below the dust-proof cover 6, and the dust-proof net 7 can be replaced. The dust-proof cover 6 is tightly combined with the steel pipe and fixed with screws 5. Small ventilation holes 601 are provided on its surface to facilitate the detection of relative humidity and moisture.

[0025] The temperature, humidity, and moisture sensors embedded in the rod body are the core components, and they respectively play an important role in detecting the temperature, humidity, and moisture content of the grain pile.

[0026] First, temperature and humidity sensors usually use components such as thermistors, thermocouples, or integrated temperature sensors as temperature measuring elements. The resistance value or output voltage of these components changes with temperature. By measuring these changes, the temperature of the grain pile can be deduced. Common humidity detection methods include capacitive, resistive, and humidity-sensitive transistor types. Among them, capacitive humidity sensors measure humidity based on the principle that the capacitance value changes after the humidity-sensitive material absorbs water vapor; resistive humidity sensors measure humidity by the change in the resistance value of the humidity-sensitive material with humidity. Temperature and humidity sensors can detect the changes in temperature and humidity in the grain pile in real time and accurately. By monitoring the temperature and humidity data, abnormal situations in the grain pile can be detected in a timely manner, such as food deterioration caused by too high temperature, mildew caused by too high humidity, etc., and corresponding measures can be taken to deal with them to ensure food safety.

[0027] Secondly, the moisture sensor can accurately measure the moisture content in the grain pile. By monitoring the moisture content, high-moisture areas in the grain can be detected in a timely manner to prevent mildew problems caused by too high moisture.

[0028] The temperature, humidity and moisture sensor is embedded in metal tubes with different diameters for mobile detection, which is convenient for detecting and analyzing the positions, ranges and change trends of the temperature, humidity and moisture in the grain pile that need attention or treatment. At the same time, the sensor has been treated for anti-condensation and anti-fumigation when embedded in the metal tube. After the moisture in the grain particles undergoes the adsorption or desorption process, the water content of the surrounding air is the same as that in the grain particles. Therefore, as long as the relative humidity and temperature of the environment air in the grain pile are detected, the moisture of the grain particles can be calculated.

[0029] A wireless transmission module is arranged inside the rod body, which can transmit data to the remote terminal regularly so that the management personnel can timely master the situation of the granary. The function of the wireless communication module to send the detection data to the remote terminal is mainly realized through the following steps:

[0030] S1. Data collection and processing:

[0031] The temperature and humidity sensor and the moisture sensor collect the temperature, humidity and moisture data of the grain pile in real time. The data processing module receives these original data and performs necessary processing and analysis to ensure the accuracy and reliability of the data.

[0032] S2. Data packaging:

[0033] The processed data will be packaged into a format suitable for wireless communication. This usually includes adding necessary protocol headers, data segments, and check bits, etc., to ensure the integrity and accuracy of the data during transmission.

[0034] S3. Wireless communication:

[0035] The wireless communication module is responsible for sending the packaged data through the wireless channel.

[0036] S4. Remote terminal reception:

[0037] The remote terminal (such as a computer, mobile phone, data center, etc.) receives the data sent from the wireless communication module through the corresponding wireless communication interface and protocol. The remote terminal needs to decode and analyze the received data to restore the original temperature, humidity and moisture data.

[0038] An intelligent probe rod for simultaneously detecting, displaying, timing and transmitting the temperature, humidity and moisture of a grain pile in the utility model is a device that can be used flexibly and moved. Insert several probe rods appropriately at the grain storage positions where potential hazards may occur to quickly detect high-temperature points for timely treatment. The intelligent probe rod for simultaneously detecting, displaying, timing and transmitting data can move to measure the temperature, humidity and equilibrium moisture in the grain pile. This device that can be moved and used can be used flexibly in different locations, reducing the equipment purchase cost. It is convenient to actively transmit the temperature, relative humidity and equilibrium moisture of the grain to the grain depot and the superior management platform. The superior management department can also understand in detail the quantity (through the volume of the granary, the grain bulk density, that is, the weight of the grain per cubic meter, and the moisture content of the grain) and quality of the grain stored by the grain storage enterprise.

[0039] The above description of the disclosed embodiments enables those skilled in the art to implement or use the utility model. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the utility model. Therefore, the utility model will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
