Description

Technical Field

[0001] This invention belongs to the field of data logger technology, and particularly relates to a fixing device and system for data loggers. Background Technology

[0002] A data logger is an electronic instrument that acquires measurement results from sensors and stores these results for future use. It is primarily used in industrial monitoring, transportation, and logistics applications.

[0003] Current data loggers lack a structure for easy fixation during data recording. They are currently secured to the application environment only with bolts. However, bolt fixation is prone to loosening due to environmental changes (such as differences in the expansion coefficients of metal components in high summer temperatures), with a failure rate reportedly reaching 15%. Loosening leads to poor contact in the data logger, and because the system's processing speed is slow, effective backup is impossible, resulting in parameter loss, errors in operation, and an inability to make accurate judgments.

[0004] Therefore, how to solve the defects in the above-mentioned technical solutions has become one of the urgent problems to be solved in the field of data logger technology. Summary of the Invention

[0005] In view of the problems existing in the background art, the present invention provides a fixing device system for a data logger, comprising,

[0006] processor;

[0007] Simulation conditioning module;

[0008] The analog acquisition module is used to acquire data based on the parameters transmitted from the processor. The acquired data is processed by the analog conditioning module and then transmitted back to the processor. The processor uses deep learning algorithms to process the data to construct a virtual sensor.

[0009] The digital acquisition module collects data from multiple sensors and data loggers deployed on the upper cover during their operation.

[0010] The digital conditioning module processes the acquired sensor detection data to obtain a standard digital signal;

[0011] The digital output module transmits the obtained standard digital signal to the signal processing module;

[0012] The signal processing module transmits data to the first-level buffer module, where it awaits further transmission.

[0013] The first-level buffer module is used to receive digital signals from the signal processing module;

[0014] The FGPA module is used to receive transmission instructions sent from the processor to the ARM module and to transmit the received transmission instructions to the L1 cache module.

[0015] The DAM IP module is used to receive digital signals from the buffer module and transmit the received signals to the ARM module.

[0016] The ARM module is used to receive digital signals from the DAM IP module and transmit the received signals to the DMA driver module or processor, and directly transmit data to the L2 cache module through the DMA driver module.

[0017] The second-level cache module is used to perform secondary caching of received data;

[0018] The DMA driver module reads data from the L2 cache module, then transmits it to the ARM module for data processing, enabling the display unit, external power supply, electromagnetic coil, and other components of the fixed device to interact with the processor through the driver program.

[0019] Control methods for a fixed device system for a data logger, including,

[0020] Step S1: When the protective housing and the data logger are in a fixed installation state, the parameters transmitted by the processor are collected by the analog acquisition module, and the collected data is processed by the analog conditioning module and then transmitted back to the processor. The processor processes the data through a deep learning algorithm to construct a virtual sensor.

[0021] Step S2: The digital acquisition module collects data from multiple sensors deployed on the upper cover plate and the data logger during operation, and transmits the collected data to the digital conditioning module.

[0022] Step S3: The acquired sensor detection data is processed by the digital conditioning module to obtain a standard digital signal, which is then transmitted to the digital output module. The obtained standard digital signal is then transmitted to the signal processing module by the digital transmission module.

[0023] Step S4: The signal is transmitted to the first-level cache module through the signal processing module for caching, and then transmitted to the DMA IP module, and then to the ARM module through the DMA IP module. Finally, it is transmitted to the processor through the ARM module.

[0024] Step S5: If the vibration and angle data detected by the sensors deployed on the top cover plate exceed the preset values, the peripheral device can send a transmission command to the ARM module through the processor, and at the same time control the electromagnetic coil to be energized through the processor.

[0025] Step S6: When the ARM module receives the transmission instruction issued by the processor, it transmits the instruction to the FGPA module and the DMA driver module respectively through the ARM module.

[0026] Step S6: Then, the received transmission command is transmitted to the first-level cache module through the FGPA module for caching and backup.

[0027] Simultaneously, the received signal is transmitted to the DMA driver module or processor, and the data is directly transmitted to the secondary cache module through the DMA driver module for caching and backup.

[0028] Step S8: When the electromagnetic coil is energized, the first locking unit and the second locking unit of the stop block are in the locked state. At this time, the snap-fit ​​piece set on the locking connector extends out and enters the snap-fit ​​groove of the snap-fit ​​mechanism, and performs snap-fit ​​connection, so that the protective shell and the data logger are still in the fixed installation state.

[0066] The second guide block has a second sliding groove.

[0067] The first guide block has a first sliding groove.

[0068] And the thickness of the first guide block / the thickness of the semi-circular groove = 1 / 2;

[0069] Furthermore, the thickness of the first guide block / the thickness of the semi-circular groove = 1 / 2.

[0070] Optionally, a first hydraulic cylinder and a second hydraulic cylinder are respectively installed inside the first locking seat and the second locking seat.

[0071] Furthermore, the extended end of the first hydraulic cylinder is connected to a first locking clip.

[0072] Furthermore, the end face of the first locking member, which is away from the first hydraulic cylinder, is disposed on the end face of the second moving unit;

[0073] The extended end of the second hydraulic cylinder is connected to a second locking clip.

[0074] Furthermore, the end face of the second locking member, which is away from the second hydraulic cylinder, is disposed on the end face of the first moving unit.

[0075] Optionally, the first locking member extends out of the first locking seat and into the locking slot of the locking groove for engaging connection;

[0076] The second locking member extends out of the second locking seat and into the locking slot provided inside the stop block, and engages in a locking connection.

[0077] When the first locking seat and the second locking seat are in the locked state, the second locking block and the second locking stop block respectively disposed on the first locking seat and the second locking seat move toward the inside of the locking seat.

[0078] In summary, the beneficial effects of this invention are:

[0079] (1) By adding a snap-fit ​​mechanism and a locking mechanism that works with the snap-fit ​​mechanism to perform magnetic locking on the fixing device, the present invention effectively prevents the bolts used to fix the data logger from loosening due to environmental changes.

[0104] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Although exemplary embodiments are disclosed in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to facilitate a thorough understanding of the present invention and to fully convey the inventive concept to those skilled in the art.

[0105] In the description of this specification, the references to terms such as "certain embodiments," "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0106] In this invention, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; the term "multiple" refers to two or more unless otherwise explicitly defined. The terms "install," "connect," "link," and "fix" should be interpreted broadly. For example, "connect" can be a fixed connection, a detachable connection, or an integral connection; "link" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0107] To solve the above technical problems, such as Figure 1-9 As shown, this embodiment provides a fixing device for a data logger, including a data logger 10. The data logger 10 is provided with a fixing device for protection, and the fixing device and the data logger 10 are nested together and fixed by bolts.

[0108] The data logger 10 is provided with a snap-fit ​​mechanism 50, and the fixing device 10 is provided with a locking mechanism 60 that works in conjunction with the snap-fit ​​mechanism 50 to perform magnetic locking.

[0109] The fixing device includes a protective shell 30, which is made of aluminum alloy and has a hexagonal honeycomb structure inside.

[0110] The protective housing 30 is provided with an integrated connecting frame 401. The connecting frame 401 is used to connect to the connecting shaft 402 via a connector 404, and the connecting shaft 402 is provided with a bushing that connects to the mounting plate 403. In this embodiment, by rotating the connecting shaft 402, the angle of the mounting plate 403 is adjusted. By adjusting the angle of the mounting plate 403, the data logger with a fixing device can be installed at the application site by welding.

[0111] Furthermore, a sensor 20 is provided on the side end face of the upper cover plate 301 of the protective housing 30, and the sensor 20 includes a vibration sensor and a tilt sensor.

[0112] In this embodiment, those skilled in the art should understand that the present invention effectively prevents the bolts used to fix the data logger from loosening due to environmental changes by adding a snap-fit ​​mechanism and a locking mechanism 60 on the fixing device that works in conjunction with the snap-fit ​​mechanism 50 for magnetic locking.

[0113] Current data loggers lack a structure for easy fixation during data recording. They are currently secured to the application environment only with bolts. However, bolt fixation is prone to loosening due to environmental changes (such as the difference in the expansion coefficients of metal components in high summer temperatures, which can exacerbate loosening). Statistics show a fixation failure rate of up to 15%. Loosening leads to poor contact in the data logger. Because the data logger system has a slow processing speed, it cannot effectively back up data, resulting in parameter loss and errors in operation, hindering accurate judgment.

[0114] To resolve the above technical issues, please refer to Figure 1-9 As shown, a data logger system includes a data acquisition system, a data transmission and processing system, and a control and display system;

[0115] The data acquisition system includes an analog conditioning module and a digital conditioning module;

[0116] The analog acquisition module is used to acquire data based on the parameters transmitted from the processor. The acquired data is processed by the analog conditioning module and then transmitted back to the processor. The processor uses deep learning algorithms to process the data to construct a virtual sensor. The virtual sensor is used to output identification data based on real-time multi-source data input. The multi-source data is the raw data collected by the real sensors set on the data logger.

[0117] The digital acquisition module obtains sensor detection data by using multiple sets of sensors deployed on the upper cover plate and data from the data logger during operation, such as vibration and angle data of the fixed device.

[0118] The digital conditioning module processes the acquired sensor detection data to obtain a standard digital signal;

[0119] The digital output module transmits the obtained standard digital signal to the signal processing module;

[0120] The signal processing module transmits data to the first-level buffer module, where it awaits further transmission.

[0121] The first-level buffer module is used to receive digital signals from the signal processing module;

[0122] The FGPA module is used to receive transmission instructions sent from the processor to the ARM module and to transmit the received transmission instructions to the L1 cache module.

[0123] The DAM IP module is used to receive digital signals from the buffer module and transmit the received signals to the ARM module.

[0124] The ARM module is used to receive digital signals from the DAM IP module and transmit the received signals to the DMA driver module or processor, and directly transmit data to the L2 cache module through the DMA driver module.

[0125] The secondary cache module is used to buffer the received data a second time. The DMA driver module reads the data from the secondary cache module, then transmits it to the ARM module and completes the data processing, so that other devices of the fixed device, such as the display unit, external power supply, electromagnetic coil, etc., can interact with the processor through the driver program.

[0126] The transmission module (LAN communication) transmits data over the network after the data signal processing is completed.

[0127] The display module displays the transmission module.

[0128] Furthermore, the transmission module implements the data processing flow.

[0129] 1. CRC checksum and TCP / IP protocol encapsulation are used to ensure data packet integrity.

[0130] 2. Implement electrical signal conversion using a Gigabit Ethernet physical layer chip (such as RTL8211F).

[0131] 3. Built-in data cache queue (depth ≥ 128MB) to handle network jitter.

[0132] 4. Network transmission optimization

[0133] 4.1 Dynamic QoS policy prioritizes the transmission of critical monitoring data

[0134] 4.2 Supports the 802.3az energy-efficient Ethernet standard, reducing power consumption by 40%.

[0135] 4.3 Dual network port redundancy design enables hot backup of links

[0136] Furthermore, the specific steps for human-computer interaction in the display module are as follows:

[0137] 1. Visualization Processing

[0138] 1.1 Accelerating Image Rendering Using OpenGL ES 3.0

[0139] 1.2 Adaptive resolution switching (supports up to 4K@60Hz)

[0140] 1.3 Multi-screen split display (1 / 4 / 9 / 16 split screens selectable)

[0141] 2. Status monitoring interface

[0142] 2.1 Real-time display of network throughput (unit: Mbps)

[0143] 2.2 Data packet loss rate warning (threshold is configurable)

[0144] 2.3 The topology diagram dynamically displays the device connection status.

[0145] Furthermore, the method for controlling the opening and closing of the data logger fixing device using a data logger system includes the following steps:

[0146] Step S1: When the protective housing and the data logger are in a fixed installation state, the parameters transmitted by the processor are collected by the analog acquisition module, and the collected data is processed by the analog conditioning module and then transmitted back to the processor. The processor processes the data through a deep learning algorithm to construct a virtual sensor.

[0147] Step S2: The digital acquisition module collects data from multiple sensors deployed on the upper cover plate and the data logger during operation, and transmits the collected data to the digital conditioning module.

[0148] Step S3: The acquired sensor detection data is processed by the digital conditioning module to obtain a standard digital signal, which is then transmitted to the digital output module. The obtained standard digital signal is then transmitted to the signal processing module by the digital transmission module.

[0149] Step S4: The signal is transmitted to the first-level cache module through the signal processing module for caching, and then transmitted to the DMA IP module, and then to the ARM module through the DMA IP module. Finally, it is transmitted to the processor through the ARM module.

[0150] Step S5: If the vibration and angle data detected by the sensors deployed on the top cover plate exceed the preset values, the peripheral device can send a transmission command to the ARM module through the processor, and at the same time control the electromagnetic coil to be energized through the processor.

[0151] Step S6: When the ARM module receives the transmission instruction issued by the processor, it transmits the instruction to the FGPA module and the DMA driver module respectively through the ARM module.

[0152] Step S6: Then, the received transmission command is transmitted to the first-level cache module through the FGPA module for caching and backup.

[0153] Simultaneously, the received signal is transmitted to the DMA driver module or processor, and the data is directly transmitted to the secondary cache module through the DMA driver module for caching and backup.

[0154] Step S8: When the electromagnetic coil is energized, the first locking unit and the second locking unit of the stop block are in a locked state. At this time, the snap-fit ​​member 504 set on the locking connector 603 extends out and enters the snap-fit ​​groove 502 of the snap-fit ​​mechanism 50, and performs a snap-fit ​​connection, so that the protective shell and the data logger are still in a fixed installation state.

[0155] In this embodiment, those skilled in the art should understand that the data acquisition and transmission are completed by the FPGA module and the DMA module, while the data processing is completed by the ARM module, greatly improving the data processing speed. Furthermore, in application, if the vibration and angle data detected by the sensors deployed on the upper cover plate exceed the preset values, the data is cached through the first-level cache module and the second-level cache module, thereby effectively backing up the data and preventing data loss.

[0156] Meanwhile, if the vibration and angle data detected by the sensors deployed on the upper cover plate exceed the preset values ​​(when the data logger becomes loose), the processor sends a task to energize the electromagnetic coil. When the electromagnetic coil is energized, the first and second locking units of the stop are locked. At this time, the snap-fit ​​504 set on the locking connector 603 extends out and enters the snap-fit ​​groove 502 of the snap-fit ​​mechanism 50, and snaps into place, so that the protective shell and the data logger are still in a fixed installation state. This can effectively prevent the data logger from becoming loose, and at the same time, it works with the first-level cache module and the second-level cache module to cache the data, thereby effectively backing up the data and avoiding data loss.

[0157] In practical applications, traditional protective housings are nested with data loggers and secured with bolts. However, embedded installations require specialized tools for disassembly, resulting in low repair efficiency in case of failure and potential secondary damage due to the complex structure. To address these technical issues, please refer to [link to relevant documentation]. Figure 1-9 The protective housing 30 includes an upper cover plate 301, and a locking mechanism 60 is provided on the end face of the upper cover plate 301 near the data logger 10. The locking mechanism 60 is provided with at least one set of permanent magnets 701 and a coil 702 that cooperates with the permanent magnets 701, and the beginning end of the coil is connected to a power source.

[0158] Furthermore, an active unit 703 is installed on the end face of the permanent magnet 701 that is far away from the coil 702 and is closely attached thereto, and the active unit 703 is located inside the cavity of the locking structure 60.

[0159] A driven unit 80 is located on one side of the active unit 703 and is used in conjunction with the active unit 703. The two ends of the active unit 80 are slidably installed in the inner cavity groove of the locking mechanism 60. When the electromagnetic coil is de-energized, the active unit and the driven unit are in a separated state.

[0160] When in the locked state, the electromagnetic coil is energized and generates a magnetic field. This magnetic field interacts with the magnetic field of the permanent magnet. At this time, the magnetic field generated by the electromagnetic coil will counteract the holding force of the permanent magnet, causing the active unit and the driven unit to be attracted together.

[0161] Furthermore, at least one set of moving rods 607 are provided on the end face of the driven unit 80, which is away from the active unit 703, and the moving rods 607 pass through positioning holes provided on the mounting plate 602.

[0162] In this embodiment, those skilled in the art should understand that the active unit and the driven unit are in a separated state, the moving rod 607 passes through the positioning hole provided on the mounting plate 602, and the connecting post 605 passes through the guide hole provided on the connecting plate, thereby causing the second locking unit of the lock block to leave the first locking unit and release the restriction;

[0163] When the electromagnetic coil is energized, a magnetic field is generated. This magnetic field interacts with the magnetic field of the permanent magnet. The magnetic field generated by the electromagnetic coil counteracts the holding force of the permanent magnet, causing the active and passive units to engage. When the active and passive units engage, the moving rod 607 on the passive unit 80 moves away from the positioning hole on the mounting plate. Since the moving rod is movable, it cannot accurately align with the positioning hole on the mounting plate, creating a blocking state between the moving rod and the mounting plate. At this point, the connecting post moves away from the guide hole on the connecting plate 606. This locks the second locking unit of the locking block in a locked state with the first locking unit.

[0164] Furthermore, the locking mechanism 60 also includes a stop block 604 and a mounting plate 602 that is closely connected to the stop block. A connecting post 605 that is integrally formed with the mounting plate 602 is provided on the end face of the mounting plate 602 away from the stop block 604, and a through hole is provided on the connecting plate 606 for the connecting post 605 to pass through.

[0165] Furthermore, a second locking unit is welded to the stop block 604, and a first locking unit is provided on one side of the second locking unit for use in locking connection. The first locking unit is welded to the locking groove 6031 of the locking connector 603.

[0166] In this embodiment, when in the locked state, the first locking unit and the second locking unit are in a locked engagement state.

[0167] Furthermore, the locking connector 603 is provided with a compression extension spring 601. The locking connector 603, which is away from the first locking unit, passes through the housing of the locking mechanism and extends out. The locking connector 603, which is located outside the housing of the locking mechanism 60, is provided with a snap-fit ​​member 504 that is integrally formed with it.

[0168] Furthermore, the snap-fit ​​member 504 extends into the snap-fit ​​groove 502 of the snap-fit ​​mechanism 50 and engages in a snap-fit ​​connection. The snap-fit ​​groove 502 is disposed within the positioning post 501, and the positioning post 501 is mounted on the top end face of the data logger 10.

[0169] In this embodiment, those skilled in the art should understand that when in the locked state, the snap-fit ​​member 504 extends into the snap-fit ​​groove 502 to perform a snap-fit ​​connection.

[0170] Furthermore, a third locking seat 6033 is integrally formed with the locking connector 603 on the end face of the locking connector 603 away from the snap-fit ​​connector 504. The third locking seat 6033 is hinged to the locking connecting rod 6034, and the locking connecting rod 6034 away from the third locking seat 6033 is installed on the end face of the stop block 604 by a fixed connection method, such as welding, fastening bolts or other connection methods.

[0171] In this embodiment, those skilled in the art should understand that the active unit and the driven unit are in a separated state, the moving rod 607 passes through the positioning hole provided on the mounting plate 602, and the connecting post 605 passes through the guide hole provided on the connecting plate, thereby causing the second locking unit of the lock block to leave the first locking unit and release the restriction;

[0172] When the electromagnetic coil is energized, a magnetic field is generated. This magnetic field interacts with the magnetic field of the permanent magnet. At this time, the magnetic field generated by the electromagnetic coil will counteract the holding force of the permanent magnet, causing the active unit and the driven unit to attract each other. When the active unit and the driven unit attract each other, the moving rod 607 set on the driven unit 80 will move away from the positioning hole set on the mounting plate. When the moving rod 607 moves away from the positioning hole on the mounting plate, since the moving rod is movable, it cannot be accurately aligned with the positioning hole on the mounting plate. At this time, the moving rod and the mounting plate are in a blocking state. At this time, the connecting column moves away from the guide hole set on the connecting plate 606, so that the second locking unit of the stop block and the first locking unit are in a locked state.

[0173] At this time, the snap-fit ​​member 504 set on the locking connector 603 extends out and enters the snap-fit ​​groove 502 of the snap-fit ​​mechanism 50, and performs a snap-fit ​​connection so that the protective shell is installed on the data logger.

[0174] Furthermore, the first locking unit includes a first locking seat 6081, and the second locking unit includes a second locking seat 6082, with the first locking seat 6081 and the second locking seat 6082 disposed opposite to each other.

[0175] The first locking seat 6081 is fixedly installed on the inner wall end face of the locking groove 6031.

[0176] The second locking seat 6082 is welded to the inside of the stop block 604;

[0177] Both the first locking seat 6081 and the second locking seat 6082 have mounting plates welded inside.

[0178] Furthermore, the mounting plates located within the first locking seat 6081 and the second locking seat are respectively provided with a first guide block 6093 and a first guide block 6096. When the end faces of the first guide block and the first guide block 6096 are in close contact, an arc-shaped groove with a circular shape is formed within the two sets of end faces. A semi-circular second moving unit 6092 and a first moving unit 6095 are respectively provided within the arc-shaped groove of the first guide block and the first guide block 6096.

[0179] The second guide block 6093 has a second sliding groove 6091 inside.

[0180] The first guide block 6096 has a first groove 6094 inside.

[0181] And the thickness of the first guide block / the thickness of the semi-circular groove = 1 / 2;

[0182] Furthermore, the thickness of the first guide block 6096 / the thickness of the semi-circular groove = 1 / 2. By providing a semi-circular groove at a general position within the guide block, the locking mechanism on the moving unit will not experience jamming or obstruction during rotation.

[0183] Furthermore, a first hydraulic cylinder 6083 and a second hydraulic cylinder 6088 are respectively installed in the first locking seat and the second locking seat by means of fastening bolts or other fixed connections.

[0184] Furthermore, the extended end of the first hydraulic cylinder 6083 is connected to a first locking member 6086, and the end face of the first locking member away from the first hydraulic cylinder is disposed on the end face of the second moving unit 6092.

[0185] The extended end of the second hydraulic cylinder 6088 is connected to a second locking member 6089, and the end face of the second locking member 6089, which is away from the second hydraulic cylinder 6088, is disposed on the end face of the first moving unit 6095.

[0186] Furthermore, the first locking member 6086 extends out of the first locking seat 6081 and extends into the locking slot of the locking groove 6031 to perform a locking connection;

[0187] The second locking member 6089 extends out of the second locking seat 6082 and into the locking slot provided inside the stop block 604, and engages in a locking connection.

[0188] Furthermore, when the first locking seat and the second locking seat are in the locked state, the second locking block 6085 and the second locking block 6087 respectively disposed on the first locking seat and the second locking seat move toward the inside of the locking seat.

[0189] In this embodiment, those skilled in the art should understand that when the first locking seat and the second locking seat are in a separated state, the end face of the first moving unit 6095 extends out of the arc-shaped groove at the position of the first guide block and is arranged parallel to the end face of the second locking block 6085 disposed in the second locking seat.

[0190] At this time, the first locking member 6086 set on the first moving unit 6095 is parallel to the inner wall of the locking groove 6031, and the first locking member does not extend into the locking groove of the locking groove.

[0191] The end face of the second moving unit 6092 extends out of the arc-shaped groove at the position of the second guide block and is arranged parallel to the end face of the first locking block 6087 disposed in the first locking seat.

[0192] At this time, the second locking member 6089 set on the second moving unit 6092 is parallel to the end face of the stop block, and the second locking member 6089 is not inserted into the locking groove of the stop block.

[0193] In this embodiment, those skilled in the art should understand that when the bolts used to fix the data logger loosen, and the vibration and angle data detected by the sensors deployed on the upper cover plate exceed the preset values, the processor energizes the electromagnetic coil. When the electromagnetic coil is energized, a magnetic field is generated. This magnetic field interacts with the magnetic field of the permanent magnet. At this time, the magnetic field generated by the electromagnetic coil will counteract the holding force of the permanent magnet, causing the active unit and the driven unit to engage. When the active unit and the driven unit engage, the moving rod 607 set on the driven unit 80 will move away from the positioning hole set on the mounting plate 602. At this time, the first locking unit and the second locking unit of the stop block are in a locked state. At this time, the snap-fit ​​member 504 set on the locking connector 603 extends out and enters the snap-fit ​​groove 502 of the snap-fit ​​mechanism 50, and engages to install the protective shell on the data logger, thereby effectively preventing the data logger from loosening.

[0194] Conversely, in the initial state, the electromagnetic coil is de-energized, and the active unit and the driven unit are separated. At this time, the movable lever on the driven unit passes through the positioning hole on the mounting plate, releasing the restriction between the movable lever and the mounting plate. Under the force of the compression spring, the locking connecting rod drives the stop block to move towards the connecting plate. At the same time, the sensor in the locking unit detects this and transmits the signal to the processor. The processor controls the hydraulic cylinder to start, and the first and second hydraulic cylinders retract simultaneously, thereby driving the locking clip to leave and releasing the restriction between the first and second locking units.

[0195] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
