Description

Technical Field

[0001] The present invention relates to the field of laboratory safety monitoring, and particularly to a laboratory monitoring device based on the Internet of Things. Background Art

[0002] With the continuous development of computer technology, various technologies have been continuously researched, developed and applied. In order to improve the popularization scope of technologies, corresponding laboratory simulation devices are usually designed to help relevant personnel learn and test new technologies. In the experiment of Internet of Things technology, relevant personnel need to conduct actual operations on site. For beginners, although this form of training can quickly get started, it is also easy to cause equipment failures due to misoperations. To address this problem, various sensors are usually set on laboratory-related equipment to detect relevant data during the operation of the equipment, and a quick alarm is issued when an abnormality occurs to avoid dangerous situations. However, there are still certain problems, which are specifically as follows:

[0003] The existing laboratory detection equipment usually monitors relevant data of the laboratory through temperature sensors, humidity sensors, voltage and current detection equipment. When an abnormality occurs, an alarm message is sent to remind the operator. However, the information feedback by this detection needs to be viewed manually. Since the program operation in the computer field takes a long time, there is often a situation where the operator is not in front of the equipment. In this case, the equipment's protection circuit is usually relied on for fault protection, which will seriously affect the service life of the equipment. Summary of the Invention

[0004] In view of the deficiencies of the existing technology, the present invention provides the following technical solutions:

[0005] A laboratory monitoring device based on the Internet of Things, comprising: a housing, an adjustment component, a controller, and a data monitoring module for detecting the working data of the device.

[0006] Specifically, one side of the housing is provided with an equipment slot and a connection slot for installing laboratory equipment. The adjustment component includes a limiting cylinder located inside the connection slot, a lifting plate linearly lifting along the inner wall of the limiting cylinder, and a heat conduction tube inserted from the upper end of the limiting cylinder. Arc-shaped pins are integrally formed on both sides of the heat conduction tube. A core wire two is penetrated through the inside of the heat conduction tube. A core wire one is penetrated through the center position of the lifting plate. A through groove is provided on the surface of the limiting cylinder. A protruding part two is provided on the inner wall of the through groove. An arc-shaped jack is provided on one side of the protruding part two. The pins are inserted into the inside of the jack in a rotating manner. A rubber part is filled in the inside of the jack. When the device is working, the heat of the core wire one and the core wire two is transferred to the rubber part inside the protruding part through the heat conduction tube. When the temperature is abnormal, the expansion generated by the rubber part pushes the pins out of the jack.

[0007] As an improvement of the above technical solution, a concave groove is provided on the inner wall of the second protruding part. On both sides of the lifting plate, there are first protruding parts inserted into the interior of the concave groove. The concave groove is a rectangular notch vertically penetrating downward to the outside of the second protruding part, and the first protruding part moves up and down along the inner wall of the concave groove.

[0008] As an improvement of the above technical solution, a spring is integrally formed on the lower end surface of the lifting plate. A wire conduit penetrates into the inner side of the spring. The upper end of the wire conduit is fixed to the lifting plate. The first core wire penetrates and is inserted into the interior of the wire conduit. Through mounting grooves are provided on the upper and lower walls of the inner wall of the connection groove.

[0009] As an improvement of the above technical solution, a positioning seat is provided on the upper end surface of the housing. A number of limiting rings are fixed on the surface of the positioning seat. The heat conduction tube is inserted by the limiting rings. A torsion spring is connected to the outside of the heat conduction tube, and the other end of the torsion spring is fixed to the limiting ring. A detachable interface is electrically connected to the upper end surface of the second core wire.

[0010] As an improvement of the above technical solution, a telescopic rod is provided inside the connection groove. The telescopic end of the telescopic rod is fixed with a third baffle. The surface of the third baffle is provided with the same number of slots as the number of limiting cylinders. Both sides of the slot have notches for passing the pins. At a position near the pin passing through the slot, a plug plate extending linearly in the direction of the lifting plate is integrally formed. When the pin is inserted into the interior of the jack, the plug plate is inserted into the gap between the tail of the pin and the second protruding part.

[0011] As an improvement of the above technical solution, heat dissipation plates are detachably fixed on both sides of the equipment slot. A first baffle is detachably fixed on the front end surface of the equipment slot. A second baffle is detachably fixed on the front end surface of the connection groove.

[0012] As an improvement of the above technical solution, a retaining wall is integrally formed and fixed on the upper end surface of the housing. The retaining wall is in a C shape, and the orientation of the concave part of the retaining wall is the same as the setting direction of the first baffle.

[0013] As an improvement of the above technical solution, the data monitoring module at least includes a temperature detection module, a voltage detection module, a current detection module, and a humidity detection module. The temperature detection module is used to detect the working temperature of the equipment installed in the equipment slot. The voltage detection module is used to detect the working voltage of the equipment installed in the equipment slot. The current detection module is used to detect the working current of the equipment installed in the equipment slot. The humidity detection module is used to detect the spatial humidity in the equipment slot and the connection groove.

[0014] As an improvement to the above technical solution, the controller includes a wireless module, a main control module, an alarm module, and a power supply module. The wireless module is used to receive the data sent during the detection by the temperature detection module, the voltage detection module, the current detection module, and the humidity detection module. The main control module is used to execute a preset command according to the data. The alarm module executes an alarm action according to the command of the main control module. The power supply module supplies power to at least the telescopic rod and the main control module.

[0015] As an improvement to the above technical solution, when the temperature rises to 100 °C, the length change of the rubber part due to heat expansion is greater than the difference between the length of the jack and the length of the rubber part.

[0016] Advantages of the present invention:

[0017] Through the set adjustment component and its related auxiliary structures, it is possible to feedback the high-temperature situation generated by computer-related equipment to the structure through a simple structure set at the connection, forming an automatic open-circuit function for the connection between the first core wire and the second core wire. When a fault occurs, even if the operator is not in front of the equipment, it is possible to disconnect and protect the circuit before the fault breaks out, thus avoiding the occurrence of danger.

Detailed implementation mode

[0030] The following uses specific examples to illustrate the implementation mode of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation modes. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0031] Existing laboratory testing equipment usually monitors relevant data in the laboratory through temperature sensors, humidity sensors, voltage and current detection equipment. When an abnormality occurs, an alarm message is sent to remind the operator. However, the information feedback by this detection needs to be viewed manually. Since the program operation in the computer field takes a long time, there is often a situation where the operator is not in front of the equipment. In this case, usually only the protection circuit of the equipment can be relied on for fault protection, which will seriously affect the service life of the equipment.

[0032] To solve this problem, please refer to Figures 1 to 11 , and provide an Internet of Things-based laboratory monitoring device, including: a housing 10, an adjustment component 20, a controller 30, and a data monitoring module 40 for detecting the working data of the equipment.

[0033] Specifically, one side of the housing 10 is provided with an equipment slot 11 for installing laboratory equipment and a connection slot 12. The adjusting assembly 20 includes a limiting cylinder 23 located inside the connection slot 12, a lifting plate 22 that linearly moves up and down along the inner wall of the limiting cylinder 23, and a heat-conducting tube 24 inserted into the upper end of the limiting cylinder 23. Arc-shaped pins 241 are integrally formed on both sides of the heat-conducting tube 24. A second core wire 242 is disposed through the inside of the heat-conducting tube 24. A first core wire 224 is disposed through the center of the lifting plate 22. A through groove 231 is formed on the surface of the limiting cylinder 23. A second protruding portion 232 is provided on the inner wall of the through groove 231. An arc-shaped jack 233 is formed on one side of the second protruding portion 232. The pins 241 are inserted into the inside of the jack 233 in a rotatable manner. A rubber member 235 is filled in the inside of the jack 233. When the equipment is working, the heat of the first core wire 224 and the second core wire 242 is transferred to the rubber member 235 inside the protruding portion through the heat-conducting tube 24. When the temperature is abnormal, the expansion generated by the rubber member 235 will push the pins 241 out of the jack 233.

[0034] During use, first install the equipment related to the experiment inside the equipment slot 11, then connect the connecting wire of the corresponding equipment to the first core wire 224, and press down the entire heat-conducting tube 24 until it is pressed into the inside of the limiting cylinder 23. At this time, rotate the entire heat-conducting tube 24. Due to the limitation of the second protruding portion 232 inside it, the entire heat-conducting tube 24 cannot rotate at this time. When the pins 241 move to the position of the jack 233, the pins 241 can be inserted into the inside of the jack 233. At this time, the installation of the entire heat-conducting tube 24 is completed. Then connect the connecting wire of the external equipment to the second core wire 242 to complete the overall connection. When the experiment is carried out, an electric current will pass between the first core wire 224 and the second core wire 242. When a circuit fault occurs, different from the fault of the mechanical structure, a high temperature will occur in the circuit, and this high temperature will be transferred to the rubber member 235 through the heat-conducting tube 24. During this temperature change process, the rubber member 235 continuously changes until the entire pins 241 are pushed out of the inside of the jack 233. At this time, since the second core wire 242 loses the position limitation of the pins 241, the lifting plate 22 will move upward, thereby pushing the first core wire 224 and the second core wire 242 upward. When the upward movement reaches a certain extent, the lifting plate 22 descends. As long as the ascending and descending speeds are relatively fast, the connection between the first core wire 224 and the second core wire 242 can be disconnected during the descending process, so that the connected equipment forms an open circuit.

[0035] In the above solution, it is necessary to ensure that the elastic change of the rubber part 235 can push out the pin 241. Since the optimal operating temperature of the computer is in the sixties or seventies degrees Celsius, when the temperature reaches 100 °C, it is generally considered that the computer is not operating normally. This requires ensuring that when the temperature rises to 100 °C, the length change caused by the thermal expansion of the rubber part 235 is greater than the difference between the length of the jack 233 and the length of the rubber part 235. Of course, although it is restricted to be greater, it cannot be too long. Preferably, the length is exactly equal to this length. The specific calculation can be derived according to the calculation method of the coefficient of thermal expansion, as follows:

[0036]

[0037] Among them, ΔL is the length change due to expansion, L is the original length, ΔT is the temperature change, and α is the coefficient of thermal expansion.

[0038] If it is assumed that the initial temperature is 0 °C, the original length is 1 cm, and the length change is 1 cm, then through calculation, the coefficient of thermal expansion can be obtained as , and the material that can relatively easily achieve this coefficient of thermal expansion is usually rubber material, and the rubber material has a certain insulation property, which also meets the application in the computer. Therefore, it is usually possible to use a filled rubber part 235 to achieve this.

[0039] To ensure the stability of the lifting plate 22 during the lifting process, please refer to Figures 1 to 7 , a recessed groove 234 is provided on the inner wall of the protruding part two 232, and protruding parts one 222 are provided on both sides of the lifting plate 22. The protruding parts one 222 are inserted into the inside of the recessed groove 234. The recessed groove 234 is a rectangular notch that vertically penetrates to the outside of the protruding part two 232. The protruding parts one 222 move up and down along the inner wall of the recessed groove 234.

[0040] A position limit is formed through the cooperation between the protruding part one 222 and the recessed groove 234. The structure is similar to a key connection. This connection method can limit the axial rotation while ensuring that the shaft body can move linearly. To further improve the lifting function of the lifting plate 22, please refer to Figures 1 to 7 , specifically, a spring 221 is integrally formed on the lower end surface of the lifting plate 22. A wire tube 223 penetrates into the inside of the spring 221. The upper end of the wire tube 223 is fixed to the lifting plate 22. A core wire one 224 penetrates and is inserted into the inside of the wire tube 223. Through holes are provided on the upper and lower inner walls of the connection groove 12.

[0041] That is, the bottom of the lifting plate 22 uses a spring 221 to achieve lifting. When the entire heat conduction tube 24 is pressed down, the spring 221 is compressed. When the pin 241 disengages from the inside of the jack 233, the spring 221 will generate a force for restoring deformation. Since this force comes from the spring 221, when restoring deformation, the upward movement speed is relatively fast. And because the spring 221 will shake after restoring deformation, the heat conduction tube 24 located above it will be continuously hit by the shake. During this shaking process, the upper heat conduction tube 24 usually generates a slight rotation. However, due to the relatively dense internal structure, even if the rotation is very small, it will cause extrusion between the arc-shaped pin 241 and the protrusion two 232, thus blocking. In this solution, there is an extremely small situation where the pin 241 can be inserted back into the original position. But during the previous process of deformation recovery, the bottom of the lifting plate 22 and the heat conduction tube 24 will continuously collide and separate. During this process, the connection between the core wire one 224 and the core wire two 242 will be disconnected, thus forming an open circuit. Since the connection is disconnected, it usually triggers the power-off function of the device. Therefore, even if the core wire one 224 and the core wire two 242 come into contact again after subsequent stabilization, they will not be re-conducted.

[0042] Although the device has the function of automatically disconnecting the power connection in case of an open circuit, there are still some devices that do not have this function. In order to be applicable to such devices, please refer to Figures 1 to 7 , a positioning seat 21 is provided on the upper end surface of the housing 10. A number of limiting rings 211 are fixed on the surface of the positioning seat 21. The heat conduction tube 24 is inserted through the limiting rings 211. A torsion spring (not shown in the figure) is connected to the outside of the heat conduction tube 24, and the other end of the torsion spring is fixed to the limiting ring 211. The upper end surface of the core wire two 242 is electrically connected to a detachable interface 243.

[0043] Although not shown in the figure, those skilled in the art should be able to know that the heat conduction tube 24 is inserted into the middle of the torsion spring. When one end of the torsion spring is fixed to the heat conduction tube 24 and the other end is fixed to the limiting ring 211, in this case, if the heat conduction tube 24 rotates, when the external force disappears, the heat conduction tube 24 will return to its original position. In this case, only need to make the insertion direction of the pin 241 opposite to the direction of the torsion spring restoring deformation. In this case, the pin 241 will be more stable under the extrusion of the torsion spring. And when it needs to be disconnected, once the pin 241 disengages from the inside of the through groove 231, it will immediately rotate automatically. After this rotation, the pin 241 will not be inserted into it again. However, this structural design will also cause the rubber part 235 that can normally expand by 1 cm to not be able to expand by 1 cm. Therefore, when designing the torsion spring for assistance, it is also necessary to lengthen the length of the rubber part 235 or use a material with a higher expansion coefficient to ensure that the expanded length can push the pin 241 out of the inside of the jack 233.

[0044] In the foregoing solution, once the temperature exceeds the threshold, there will be a problem of automatic disconnection. During the experiment, there are not only regular tests but also load tests, etc. Therefore, in order to avoid automatic disconnection between structural components during the load test, a locking structure needs to be designed. Specifically, please refer to Figures 1 to 10 , a telescopic rod 122 is arranged inside the connection groove 12. A third baffle 123 is fixed at the telescopic end of the telescopic rod 122. The surface of the third baffle 123 is provided with slots 124 having the same number as the limit cylinders 23. Both sides of the slots 124 have notches for passing through the pins 241. An insertion plate 125 extending linearly in the direction of the lifting plate 22 is integrally formed at a position of the slot 124 close to the passing position of the pin 241. After the pin 241 is inserted into the inside of the insertion hole 233, the insertion plate 125 is inserted into the gap between the tail of the pin 241 and the second protrusion 232.

[0045] The lifting of the third baffle 123 is controlled by the lifting of the telescopic rod 122, and the lifting of the third baffle 123 can drive the bottom insertion plate 125 to disengage from the through groove 231. When the insertion plate 125 is inserted into the gap between the tail of the pin 241 and the second protrusion 232, in this case, the internal rubber part 235 will be extruded by an external force. This extrusion force is extremely large, so that the rubber part 235 cannot completely push the pin 241 out of the insertion hole 233, and thus cannot disconnect the connection between the first core wire 224 and the second core wire 242, thereby achieving the locking function of the structural components in special experiments.

[0046] To further improve the solution of this embodiment, please refer to Figure 1 And Figure 2 , heat dissipation plates 111 are detachably fixed on both sides of the equipment groove 11, a first baffle 112 is detachably fixed on the front end face of the equipment groove 11, and a second baffle 121 is detachably fixed on the front end face of the connection groove 12.

[0047] The heat dissipation plates 111 provide heat dissipation space on both sides, and the first baffle 112 and the second baffle 121 on the front end face provide a sealing function. They can be removed when internal equipment needs to be repaired or disassembled. Different from conventional experiments, in order to avoid the experiment from affecting other people or equipment, the entire housing 10 needs to be covered during the experiment. Based on this, please refer to Figure 1 , specifically, a surrounding wall 113 is integrally formed and fixed on the upper end face of the housing 10. The surrounding wall 113 is in a C shape, and the orientation of the concave part of the surrounding wall 113 is the same as the setting direction of the first baffle 112.

[0048] The surrounding wall 113 provides shielding protection on the outside to avoid affecting the surrounding environment or equipment.

[0049] To further improve the technical solution of the data monitoring module 40, please refer toFigure 11 The data monitoring module 40 at least includes a temperature detection module 41, a voltage detection module 42, a current detection module 43, and a humidity detection module 44. The temperature detection module 41 is used to detect the operating temperature of the device installed in the device slot 11. The voltage detection module 42 is used to detect the operating voltage of the device installed in the device slot 11. The current detection module 43 is used to detect the operating current of the device installed in the device slot 11. The humidity detection module 44 is used to detect the space humidity in the device slot 11 and the connection slot 12.

[0050] Among them, the temperature detection module 41 usually uses various types of temperature sensors to detect temperature. The humidity detection module 44 usually uses various types of humidity sensors to detect temperature. The voltage detection module 42 and the current detection module 43 are usually integrated voltage detection circuits or current detection circuits. In this embodiment, no improvement is made to the corresponding detection scheme, so the specific circuit detection scheme is not limited.

[0051] To further improve the technical solution of the controller 30, please refer to Figure 11 The controller 30 includes a wireless module 31, a main control module 32, an alarm module 33, and a power supply module 34. The wireless module 31 is used to receive the data sent during the detection by the temperature detection module 41, the voltage detection module 42, the current detection module 43, and the humidity detection module 44. The main control module 32 is used to execute preset commands according to the data. The alarm module 33 executes alarm actions according to the commands of the main control module 32. The power supply module 34 supplies power to at least the telescopic rod 122 and the main control module 32.

[0052] The data is received through the wireless module 31. The wireless module 31 is usually various wireless connection chips, including but not limited to wifi, Bluetooth, or radio frequency connection. The main control module 32 is usually a driver board integrated with a control chip, mainly used to execute one or more related preset commands. The alarm module 33 usually uses a buzzer and a warning light. It gives a sound alarm through the buzzer and a light alarm through the warning light to prompt the operator that the device is in an abnormal state. When the main control module 32 receives a command, it usually controls the time when the telescopic rod 122 is in the contracted state. For example, when performing a device load test, protection can be carried out by controlling the contraction test of the telescopic rod 122. When the load test exceeds the preset time and no corresponding operation is still performed, it is determined that there is no one in front of the current device. In this case, the experimental data is usually collected. If the collected experimental data still judges that the situation is abnormal, the telescopic rod 122 is controlled to extend, so that the baffle three 123 releases the restriction on the position of the pin 241. In this case, after a period of time, the rubber part 235 will continue to expand, so as to withdraw the pin 241 and complete the automatic shutdown function in the unmanned state.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
