Description

Technical Field

[0001] The invention relates to the field of grain environment monitoring, in particular to a visual grain monitoring terminal. Background Art

[0002] There is an old Chinese saying: "Food is the first necessity of the people". Food is related to people's survival. my country is a country with a large population and consumes a large amount of food every year. Among them, food storage is very important. Improper food storage management will lead to food pests and mildew, making the food inedible and even unusable as seeds for sowing. According to relevant statistics, my country's food losses are as high as hundreds of millions of yuan each year, so food storage management is particularly important.

[0003] During storage, we need effective means to monitor the temperature, humidity, pests and other conditions of grain in order to respond to any problems in a timely manner. At the same time, we also need intelligent and precise monitoring methods to provide grain management personnel with accurate data and give reasonable handling opinions to reduce manpower and material resources.

[0004] The existing temperature and humidity monitoring system has been widely used in grain storage. The system has a simple structure and is distributed in the grain in a network shape. It is connected to various sensors on the surface of the grain through signal lines. The temperature and humidity monitoring system can detect the temperature and humidity in the grain and feed it back to the system. The management personnel will judge the changes in temperature and humidity based on their own experience, identify the reasons for the changes in temperature and humidity, and determine whether pests are breeding and whether corresponding treatment is needed. The system has great limitations, is not intuitive enough, and cannot observe the number and type of pests in the first place. It is not convenient and intelligent for users, and it is easy to misjudge information and react slowly.

[0005] The existing wireless grain condition detection system has a relatively small application scope. It is a wireless detection system with a probe rod, a signal processing circuit board and a power supply at the upper end, and an empty rod with many small holes at the lower end. The principle is to use the characteristics of pests that love to drill small holes to lure pests into the empty rod, and use proximity switches to count pests, thereby monitoring the pest situation in grain. However, there are defects such as the number of pests is affected by small grain particles, resulting in inaccurate pest counting, and the inability to identify pest types.

[0006] The intelligent monitoring terminal for stored grain pests adds pest identification function to the temperature and humidity monitoring system and the wireless grain condition detection system. It is connected to the pest trapping tube through wiring and pipes. When the pest enters the trapping tube, the vacuum pump outside the granary sucks the pest through the pipe to the pointed image collection point for identification. The terminal requires the transformation of the granary and the laying of a large number of pipes. The construction cost is high, the structure is complex, the pipes are easily blocked, the failure rate is high, the depth is limited, and the monitoring range is extremely limited. It is complex for management personnel to operate and has high management costs, so it is not suitable for large-scale promotion.

[0007] Grain reserve management is increasingly moving towards rapidity and automation, and there is an urgent need for a visual monitoring terminal to accurately monitor the storage status of grain, provide accurate data for grain management personnel, and give reasonable processing opinions to reduce manpower and material resources. In view of the defects of the existing technology, a visual grain monitoring terminal is proposed. Summary of the invention

[0008] The purpose of the present invention is to propose a visual grain monitoring terminal to solve the problems in the background technology, realize all-round and accurate monitoring of grain temperature, humidity and insect pests in the granary, and reduce the tediousness and misjudgment of personnel management.

[0009] The technical solution adopted by the present invention is as follows:

[0010] The present invention is a visualized grain monitoring terminal, comprising a cover plate and a shell, wherein a cavity is formed by the shell and the cover plate being assembled together, and the cavity is divided into a circuit board installation chamber and an image acquisition chamber by a transparent glass sheet, wherein a circuit board, a camera, a temperature sensor, a humidity sensor, a rubber plug and a fixing block are arranged in the circuit board installation chamber, wherein the camera is fixed on the circuit board by the fixing block, and the camera faces the image acquisition chamber; the connection pins of the temperature sensor and the humidity sensor are installed on the circuit board through the rubber plug, and the rubber plug seals and separates the circuit board from the sensing ends of the temperature sensor and the humidity sensor; an air hole facing the temperature sensor and the humidity sensor is arranged on the upper end of the shell; an A hole is arranged on the shell corresponding to the image acquisition chamber, and a section of a protruding tube is arranged at one end of the A hole in the image acquisition chamber.

[0011] Traditional grain environment monitoring technologies include temperature and humidity monitoring systems and wireless grain condition detection systems, but both have limitations in monitoring the grain environment. The monitoring terminal of the present invention includes a cover plate and a shell, which can be assembled together to form a cavity inside that can accommodate a glass sheet, a circuit board, a camera, a temperature sensor, and a humidity sensor. A transparent glass sheet is arranged in the cavity to separate the cavity into a circuit board installation room and an image acquisition room, and the circuit board, the camera, the temperature sensor, and the humidity sensor are all installed in the circuit board installation room. The camera is fixed on the circuit board by a fixing block, and the camera is facing the image acquisition room. A hole A is opened on the shell corresponding to the image acquisition room. The characteristic that pests like to drill small holes is utilized to allow the pests to enter the image acquisition room through the A hole, and the camera takes pictures and videos of the pest situation in the image acquisition room to monitor the environment. The pest status of grain can be measured, and the pest type can be checked from the photographed photos to avoid misjudgment. The pests enter the picture collection chamber through the A hole and fall on the bottom of the lower end of the shell, thereby avoiding the pests from being too close to the camera and causing unclear images to be taken, thereby improving the image quality. Since the A hole in the present invention has a protruding tube at one end of the image collection chamber, it is not easy for pests to escape after entering the picture collection chamber, which is conducive to the camera's collection of pest images in the picture collection chamber, reducing the probability of missing shots, and the speed of dust accumulation in the image collection chamber will also be greatly reduced, and fine particulate matter such as grain is not easy to enter the picture collection chamber. When the monitoring terminal of the present invention is in use, the image collection chamber is located below the camera, so the glass sheet is above the image collection chamber. Due to the effect of gravity, the glass sheet will also rarely accumulate dust, which will not affect the quality of the collected images.

[0012] It is understood that most of the insecticides used in granaries are used for pest control, and the insecticides will corrode the circuit boards, thus causing the monitoring terminal to fail. In the present invention, the circuit board installation room and the image acquisition room are separated by a transparent glass sheet. Although air holes are provided on the shell for gas exchange so that the sensing ends of the temperature sensor and the humidity sensor can sense the temperature and humidity in the granary, the rubber plugs seal the sensing ends of the temperature sensor and the humidity sensor from the circuit board, so that the circuit board is in a sealed circuit board installation room and will not be corroded by dust and insecticides, thereby extending the service life of the monitoring terminal.

[0013] The present invention collects insect pest, temperature and humidity data of the grain environment in the granary through a camera, a temperature sensor and a humidity sensor, so as to facilitate comprehensive monitoring and analysis of the grain environment.

[0014] Furthermore, the middle portion of the shell is in the shape of a rectangular parallelepiped, and the two ends of the shell also include a first clamp and a second clamp. The first clamp and the second clamp are fixed to the two ends of the shell by bolts, so that the two ends of the shell are inclined; the sensing ends of the temperature sensor and the humidity sensor are arranged in the inner cavity of the first clamp, and the air hole is arranged on the first clamp.

[0015] By adopting the above structure, by setting the two ends of the shell into inclined surfaces, the monitoring terminal as a whole can be easily moved in the granary to reduce resistance, and the end where the first clamp is located is set as the upper end of the shell, and the end where the second clamp is located is set as the lower end of the shell; the sensing ends of the temperature sensor and the humidity sensor are set in the inner cavity of the first clamp and the sensing ends of the temperature sensor and the humidity sensor are separated from the image acquisition chamber with a rubber plug to prevent dust and pesticides from entering through the pores and corroding the circuit board.

[0016] Furthermore, the shell corresponding to the image acquisition chamber also includes a pin plate, the protruding tube is arranged on the pin plate, the protruding tube is inserted into the A hole and extends into the image acquisition chamber; it also includes a patch, the patch is provided with a B hole, the pin plate is arranged between the shell and the patch, at least one of the B hole and the A hole is an inclined hole, and the B hole, the protruding tube and the A hole form a non-straight through hole.

[0017] Furthermore, the inclined hole is inclined upward toward the image acquisition chamber.

[0018] With the above structure, the insect entry channel formed by the A hole of the shell, the raised tube of the pin plate and the B hole of the patch is not a straight channel, which can effectively reduce the probability of dust, fine grains and other garbage entering the image acquisition room, and effectively reduce the probability of misjudgment of pest identification; and the raised tube extending to the inside of the image acquisition room can increase the difficulty for pests to crawl out, reduce the probability of pests that have entered the image acquisition room to crawl out, and facilitate the effective collection of pest conditions.

[0019] Furthermore, a wormhole communicating with the bottom of the image acquisition chamber is provided on the side surface of the lower end of the shell.

[0020] Furthermore, a through hole communicating with the image acquisition chamber in the shell is formed on the second clamping head, and a top head, a sliding rod and a spring are arranged in the through hole. One end of the sliding rod is connected to the top head by a bolt, and the other end of the sliding rod passes through the through hole and enters the bottom of the image acquisition chamber. The spring is sleeved on the sliding rod and is arranged between the top head and the second clamping head.

[0021] Furthermore, a convex head is provided at one end of the sliding rod at the bottom of the image acquisition chamber, and the size of the convex head is larger than the size of the through hole of the second clamping head.

[0022] With the above structure, in a natural state, that is, without interference from other external forces, the top head and the slide bar sink due to the gravity of the top head and the slide bar themselves, the lower end of the top head protrudes from the clamping head, and the upper end of the slide bar moves downward, so that the worm hole is connected with the image acquisition chamber, forming a channel for removing pests and garbage, and the worm hole is in an open state, thereby discharging pests and other debris; when the monitoring terminal needs to be buried in grain, the monitoring terminal moves downward as a whole, and the spring is compressed due to the squeezing of the grain on the top head, the top head moves up into the clamping head, the slide bar moves up, the worm hole is staggered with the slide bar, the slide bar blocks the passage between the worm hole and the image acquisition chamber, the worm hole is in a closed state, and the insects cannot escape through this place, increasing the probability of the insects being photographed; and when the monitoring terminal is moved out of the granary, due to the rebound force of the spring and the gravity of the top head and the slide bar, the top head and the slide bar return to the natural state, and the worm hole opens to discharge pests and other debris.

[0023] Furthermore, a signal line is included, and the housing and the cover are both provided with a U-shaped groove matching the signal line, and a convex pattern is provided in the U-shaped groove, and the housing and the cover are assembled on the signal line. The U-shaped groove is used to place the signal line, so that the signal line is at a position specified by the housing and the cover, and the convex pattern in the U-shaped groove makes the wire sheath of the signal line pressed tighter, preventing the wire sheath from being separated from the housing when being pulled, affecting the use and aesthetics.

[0024] Furthermore, it also includes wire locks and card plates arranged at both ends of the shell, and the shell is also provided with positioning grooves matching the wire locks and card plates. The signal line includes a steel wire rope and a network cable. The steel wire rope is clamped in the positioning groove through the wire lock and card plate to connect to the shell, and the network cable is connected to the circuit board by welding.

[0025] The monitoring terminals are connected by signal lines, so there are signal lines at both ends of the monitoring terminals. The steel wire rope in the signal line is connected to the housing through the steel wire lock and the card plate in the positioning groove, so that the force of the entire monitoring terminal is transmitted through the steel wire rope, preventing damage caused by the installation process and the risk that the monitoring terminal cannot be taken out of the grain. The steel wire rope in the monitoring terminal can be connected or disconnected. The network cable that transmits the signal in the signal line is connected to the circuit board by welding. Since the network cable is not subjected to force, the signal transmission is more stable.

[0026] Furthermore, the circuit board includes a short circuit board and a long circuit board, the camera, temperature sensor and humidity sensor are installed on the short circuit board, the network cable is welded on the long circuit board, and the two circuit boards are connected by a flat cable. The circuit board is divided into two parts, the short circuit board directly supplies power to the camera, temperature sensor and humidity sensor and processes signals, and the long circuit board connects the signal lines between the monitoring terminals. The two circuit boards are connected by a flat cable, and the assembly is simple.

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0028] 1. The present invention is a visualized grain monitoring terminal. The circuit board installation room and the image acquisition room are separated by a transparent glass sheet, and the rubber plug seals the sensing ends of the temperature sensor and the humidity sensor from the circuit board, so that the circuit board is in the sealed circuit board installation room and will not be corroded by dust and pesticides, thereby extending the service life of the monitoring terminal.

[0030] 3. The present invention is a visual grain monitoring terminal. The insect entry channel formed by the shell, the pin plate and the patch is not a straight channel, which can effectively reduce the probability of dust, fine grain particles and other garbage entering the image collection room, and effectively reduce the probability of misjudgment of pest identification; and the raised tube extending to the inside of the image collection room can increase the difficulty of pests crawling out, reduce the probability of pests that have entered the image collection room crawling out, and facilitate the effective collection of pest conditions.

[0031] 4. The present invention is a visual grain monitoring terminal. A top head, a sliding rod and a spring are arranged in the through hole of the second clamp. In a natural state, the sliding rod sinks, and the worm hole is connected with the insect collecting chamber to form a channel for removing garbage, thereby discharging pests and other debris; when the sliding rod is squeezed, the spring is compressed between the groove and the clamp, the sliding rod blocks the bottom of the insect collecting chamber, the worm hole is closed, and the insects cannot escape through this place, thereby increasing the probability of the insects being photographed.

[0032] 5. The present invention is a visual grain monitoring terminal. Pests enter the image collection chamber through the insect entrance channel and fall to the bottom of the lower end of the shell, so as to avoid the pests being too close to the camera and causing unclear images, thereby improving the image quality.

[0035] 8. The present invention is a visual grain monitoring terminal, which collects the pest, temperature and humidity data of the grain environment in the granary through cameras, temperature sensors and humidity sensors. It can directly observe the state of the grain, observe the pest situation in the grain, avoid misjudgment, and conduct comprehensive monitoring and analysis of the grain environment.

[0047] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0048] Embodiment 1

[0049] like Figure 1-8 As shown, the present invention is a visualized grain monitoring terminal, comprising a cover plate 1 and a shell 2, wherein the shell 2 and the cover plate 1 are assembled to form a cavity, and the cavity is divided into a circuit board installation chamber and an image acquisition chamber by a transparent glass sheet 3, wherein a circuit board 4, a camera 5, a temperature sensor 6, a humidity sensor 7, a rubber plug 8 and a fixing block 9 are arranged in the circuit board installation chamber, wherein the camera 5 is fixed on the circuit board 4 by the fixing block 9, and the camera 5 faces the image acquisition chamber; the connection pins of the temperature sensor 6 and the humidity sensor 7 are installed on the circuit board 4 through the rubber plug 8, and the rubber plug 8 seals and separates the circuit board 4 from the sensing ends of the temperature sensor 6 and the humidity sensor 7, and an air hole 21 facing the temperature sensor 6 and the humidity sensor 7 is provided at the upper end of the shell 2; an A hole 22 is provided on the shell 2 corresponding to the image acquisition chamber, and a section of a raised tube 23 is provided at one end of the A hole 22 in the image acquisition chamber.

[0050] Traditional grain environment monitoring technologies include temperature and humidity monitoring systems and wireless grain condition detection systems, but both have limitations in monitoring the grain environment. The monitoring terminal of the present invention includes a cover plate 1 and a shell 2. The shell 2 and the cover plate 1 can be assembled together by bolts, and a cavity capable of accommodating a glass sheet 3, a circuit board 4, a camera 5, a temperature sensor 6, and a humidity sensor 7 is formed inside. A transparent glass sheet 3 is arranged in the cavity to separate the cavity into a circuit board installation room and an image acquisition room, and the circuit board 4, the camera 5, the temperature sensor 6, and the humidity sensor 7 are all installed in the circuit board installation room. The camera 5 is fixed on the circuit board 4 by a fixing block 9, and the camera 5 is facing the image acquisition room. A hole A 22 is provided on the shell 2 corresponding to the image collection chamber. By utilizing the characteristic that pests love to drill small holes 22, the pests enter the image collection chamber through the hole A 22. The camera 5 takes photos and videos of the pest situation in the image collection chamber to monitor the insect pest status of grains, and the types of pests can be checked from the photos taken to avoid misjudgment. After the pests enter the image collection chamber through the hole A 22, they fall to the bottom of the lower end of the shell 2, thereby preventing the pests from being too close to the camera 5 and causing unclear images, thereby improving the image quality. A fill light can also be provided next to the camera 5, which can assist the camera 5 in taking photos or videos, so that the staff can clearly check the insect pest situation of grains in the photos or videos. Since hole A 22 in the present invention has a protruding tube at one end of the image collection chamber, it is not easy for pests to escape after entering the image collection chamber, which is beneficial to the camera 5 to collect images of pests in the image collection chamber and reduces the probability of missing images. In addition, the speed of dust accumulation in the image collection chamber is greatly reduced, and small particles such as food are not easy to enter the image collection chamber. When the monitoring terminal of the present invention is in use, the image collection chamber is located below the camera 5, so the glass sheet 3 is above the image collection chamber. Due to the effect of gravity, the glass sheet 3 will also rarely accumulate dust, which will not affect the quality of the collected image.

[0051] It is understood that most of the devices used in the granary will use pesticides for pest control, and the pesticides will corrode the circuit board 4, thus causing the monitoring terminal to fail. In the present invention, the circuit board installation room and the image acquisition room are separated by a transparent glass sheet 3. The temperature sensor 6 and the humidity sensor 7 both have a sensing end for sensing temperature and humidity and a connection pin for connecting to the circuit board 4. Although the housing 2 is provided with air holes 21 for gas exchange so that the sensing ends of the temperature sensor 6 and the humidity sensor 7 can sense the temperature and humidity in the granary, the rubber plug 8 separates the sensing ends of the temperature sensor 6 and the humidity sensor 7 from the circuit board 4 in a sealed manner, so that the circuit board 4 is in a sealed circuit board installation room and will not be corroded by dust and pesticides, thereby extending the service life of the monitoring terminal. In this embodiment, there are 4 air holes 21, and the joints between the cover plate 1 and the housing 2 and the joints between the rubber plug 8, the glass sheet 3 and the housing 2 are all provided with sealing grooves and coated with sealant to make them sealed.

[0052] The present invention collects insect pest, temperature and humidity data of the grain environment in the granary through the camera 5, the temperature sensor 6 and the humidity sensor 7, so as to facilitate comprehensive monitoring and analysis of the grain environment.

[0053] Embodiment 2

[0054] This embodiment is a further explanation of the present invention.

[0055] like Figure 1-4 As shown, this embodiment is based on the first embodiment. In a preferred embodiment of the present invention, the middle part of the shell 2 is in the shape of a rectangular parallelepiped, and the two ends of the shell also include a first clamp 24 and a second clamp 25. The first clamp 24 and the second clamp 25 are fixed to the two ends of the shell 2 by bolts, so that the two ends of the shell 2 are inclined; the sensing ends of the temperature sensor 6 and the humidity sensor 7 are arranged in the inner cavity of the first clamp 24, and the air hole 21 is arranged on the first clamp 24.

[0056] With the above structure, the middle part of the shell 2 is in the shape of a rectangular parallelepiped, and the circuit board and the image acquisition chamber are both arranged in the middle part of the shell 2. By setting the two ends of the shell 2 as inclined surfaces, it is convenient for the monitoring terminal to move as a whole in the granary to reduce resistance. The present invention sets the end where the first clamp 24 is located as the upper end of the shell 2, and the end where the second clamp 25 is located as the lower end of the shell 2; the sensing ends of the temperature sensor 6 and the humidity sensor 7 are set in the inner cavity of the first clamp 24 and the rubber plug 8 is used to separate the sensing ends of the temperature sensor 6 and the humidity sensor 7 from the circuit board installation chamber to prevent dust and pesticides from entering through the air hole 21 to corrode the circuit board 4.

[0057] Embodiment 3

[0058] This embodiment is a further explanation of the present invention.

[0059] like Figure 2 As shown, this embodiment is based on the above embodiment. In a preferred embodiment of the present invention, the shell 2 corresponding to the image acquisition chamber further includes a pin plate 13, and the protruding tube 23 is arranged on the pin plate 13. The protruding tube 23 is inserted into the A hole 22 and extends into the image acquisition chamber; it also includes a patch 14, and the patch 14 is provided with a B hole 141. The pin plate 13 is arranged between the shell 2 and the patch 14. At least one of the B hole 141 and the A hole 22 is an inclined hole, and the B hole 141, the protruding tube 23 and the A hole 22 form a non-straight through hole.

[0060] In a preferred embodiment of the present invention, the inclined hole is inclined upward toward the image acquisition chamber. In the present invention, one end where the first clamp 24 is located is set as the upper end of the shell 2, that is, the inclined hole is inclined from the outer side of the shell 2 to the upper end of the inner side of the shell 2, so that small food particles and other garbage are not easy to enter the image acquisition chamber.

[0061] With the above structure, the insect entry channel formed by the A hole 22 of the shell 2, the protruding tube 23 of the pin plate 13 and the B hole 141 of the patch 14 is not a straight channel, which can effectively reduce the probability of dust, fine grains and other garbage entering the image acquisition room, and effectively reduce the probability of misjudgment of pest identification; and the protruding tube 23 extending to the inside of the image acquisition room can increase the difficulty of pests crawling out, reduce the probability of pests that have entered the image acquisition room crawling out, and facilitate the effective collection of pest conditions.

[0062] Embodiment 4

[0063] This embodiment is a further explanation of the present invention.

[0064] like Figure 1-2 As shown, based on the above embodiment, in a preferred embodiment of the present invention, the lower end side of the shell 2 is provided with an insect leakage hole 28 connected with the bottom of the image acquisition chamber.

[0065] In a preferred embodiment of the present invention, a through hole communicating with the image acquisition chamber in the shell 2 is opened on the second clamping head 25, and a top head 15, a sliding rod 16 and a spring 17 are arranged in the through hole. One end of the sliding rod 16 is connected to the top head 15 by a bolt, and the other end of the sliding rod 16 passes through the through hole and enters the bottom of the image acquisition chamber. The spring 17 is sleeved on the sliding rod 16 and is arranged between the top head 15 and the second clamping head 25.

[0066] In a preferred embodiment of the present invention, a convex head 161 is provided at one end of the sliding rod 16 at the bottom of the image acquisition chamber, and the size of the convex head 161 is larger than the size of the through hole of the second clamping head 25 .

[0067] With the above structure, in a natural state, that is, without interference from other external forces, the top head 15 and the slide bar 16 sink due to the gravity of the top head and the slide bar 1616, the lower end of the top head 15 protrudes the clamping head, and the upper end of the slide bar 16 moves downward, so that the worm hole 28 is connected with the image acquisition chamber, forming a channel for removing pests and garbage, and the worm hole 28 is in an open state, thereby removing pests and other debris; when the monitoring terminal needs to be buried in the grain, the monitoring terminal moves downward as a whole, and due to the impact of the grain on the top head 15 The extrusion causes the spring 17 to be compressed, the top head 15 moves up into the clamping head, the slide bar 16 moves up, the worm hole and the slide bar 16 are staggered, the slide bar 16 blocks the passage between the worm hole and the image acquisition chamber, the worm hole 28 is in a closed state, the insects cannot escape through this place, and the probability of the insects being photographed increases; and when the monitoring terminal is moved out of the granary, due to the rebound force of the spring 17 and the gravity of the top head 15 and the slide bar 16, the top head 15 and the slide bar 16 return to the natural state, and the worm hole 28 opens to discharge pests and other debris.

[0068] Embodiment 5

[0069] This embodiment is a further explanation of the present invention.

[0070] like Figure 2-3 As shown, based on the above embodiment, in a preferred embodiment of the present invention, this embodiment further includes a signal line 10, and the housing 2 and the cover plate 1 are both provided with a U-shaped groove 26 matching the signal line 10, and a convex pattern is provided in the U-shaped groove 26, and the housing 2 and the cover plate 1 are assembled on the signal line 10. The U-shaped groove 26 is used to place the signal line 10, so that the signal line 10 is at a position specified by the housing 2 and the cover plate 1, and the convex pattern in the U-shaped groove 26 allows the wire sheath of the signal line 10 to be pressed tighter, so as to prevent the wire sheath from being separated from the housing 2 when being pulled, which affects the use and aesthetics.

[0071] In a preferred embodiment of the present invention, it also includes a wire lock 11 and a card plate 12 arranged at both ends of the shell 2, and a positioning groove 27 matching the wire lock 11 and the card plate 12 is also arranged in the shell 2.

The wire rope 101 is clamped in the positioning groove 27 through the wire lock 11 and the card plate 12 to connect to the shell 2, and the network cable 102 is connected to the circuit board 4 by welding.

[0072] The monitoring terminals are connected by signal lines 10, so there are signal lines 10 at both ends of the monitoring terminals. The steel wire rope 101 in the signal line 10 is clamped in the positioning groove 27 through the steel wire lock 11 and the clamping plate 12 to realize the connection between the signal line 10 and the housing 2, so that the force of the entire monitoring terminal is transmitted through the steel wire rope 101, preventing damage caused by the installation and construction process and the risk that the monitoring terminal cannot be taken out of the grain. The network cable 102 that transmits the signal in the signal line 10 is connected to the circuit board 4 by welding. Since the network cable 102 is not subjected to force, the signal transmission is more stable.
