These are used to simulate various application environments to conduct adaptability tests on electronic devices or components, in order to test whether they meet the corresponding standards or requirements. However, due to the large variety of environmental testing equipment, each device comes from different manufacturers and has different data interfaces. When it is necessary to collect and analyze data from each device or monitor the device status via data transmission lines, it is usually necessary to connect each device to a protocol converter. In a laboratory with limited space, multiple data interfaces need to be individually adapted to data cables, which not only reduces the convenience of data collection but also increases the difficulty of organizing the wiring harness. On the other hand, the complex configuration of data interfaces and wiring harnesses increases the difficulty of verifying the connectivity status of the devices, and data collection failures of some devices are easily caused by unstable or disordered wiring during the data collection process.

[0028] The following is in conjunction with the appendix Figure 1 To be continued Figure 7 The present application will be further described in detail with reference to specific embodiments.

[0029] This application discloses a protocol conversion device (hereinafter referred to as the protocol conversion device) for data acquisition from various types of environmental testing equipment. It includes a protocol conversion module 10 and a device connection module 20. The protocol conversion module 10 includes a first housing 11 and at least one protocol converter 12 disposed within the first housing 11. The protocol converter 12 is used to convert the acquired data protocol from the environmental testing equipment into a wireless communication protocol, so that the equipment data information can be collected and monitored via a network. Specifically, the protocol converter 12 includes the ability to convert data from environmental testing equipment that can only be transmitted via wired communication protocols into data compatible with Zigbee or LoRa, etc. A protocol converter 12 for wireless network protocol data; at least one data input interface 111 is integrated on one side of the housing, and each data input interface 111 is connected to a corresponding protocol converter 12 to transmit environmental device data to the protocol converter 12; the device connection module 20 includes a second housing 21 and at least one wire harness organizer 22 disposed within the second housing 21. At least one data transmission wire harness 23 is stretchably wound on the wire harness organizer 22. Specifically, with the cooperation of the wire harness organizer 22, at least one data transmission wire harness 23 can be stretched and wound around the wire harness organizer 22. One end of the data transmission harness 23 is elongated and extended so that the device interface 231 connected to one end of the data transmission harness 23 can be plugged into the corresponding environmental test equipment to obtain data from the equipment. When no equipment is connected, the data transmission harness 23 is stored in the second housing 21 under the winding action of the harness retractor 22. The side of the second housing 21 that is used to dock with the first housing 11 is provided with at least one data output interface 211. The data output interface 211 is connected to one end of the data transmission harness 23 corresponding to it, and each data output interface 211 and its corresponding data input interface 111 can be plugged and detached. The surface of the second housing 21 is also provided with at least one data output interface 211. One less signal alarm 24 is provided. Each signal indicator and its corresponding data transmission harness 23 are electrically connected. The signal alarm 24 is used to emit an audible and / or visual alarm signal when powered on. Specifically, in a preferred embodiment, the signal alarm 24 is preferably a micro-current light-emitting diode. When the data output interface 211 is plugged into the data input interface 111 and the device interface 231 is plugged into the environmental test equipment, a micro-current passes through the light-emitting diode in the data transmission device, causing the light-emitting diode to light up as a warning, indicating that the protocol converter 12 in the protocol conversion device is connected to the corresponding environmental test equipment.

[0030] When using the above-mentioned protocol conversion device, the data output interface 211 and its corresponding data input interface 111 are plugged in, so that the first box 11 and the second box 21 are connected. Then, the data transmission harness 23 is stretched and connected to the corresponding environmental test equipment, so that the protocol converter 12 can obtain the data of the corresponding environmental test equipment and send the data to the relevant monitoring equipment or analysis equipment in the form of wireless communication, so as to facilitate the monitoring or analysis of the data of the environmental test equipment.

[0031] The beneficial effects of using the above-mentioned combined fireproof distribution cabinet are as follows:

[0032] First, provided that the first box 11 and the second box 21 are fully connected, the operator only needs to pull out the data transmission harness 23 and plug it into the corresponding environmental test equipment to convert the data protocol of the environmental test equipment. This saves the step of connecting the data transmission harness 23 to the corresponding protocol converter 12 one by one, improves the convenience of data acquisition and the efficiency of connecting equipment, and facilitates the centralized management of each data transmission harness 23. This avoids the phenomenon of messy pulling and connecting of the data transmission harness 23 when there are many devices, thus simplifying the process of storing, unfolding and organizing the data transmission harness 23.

[0033] Second, when there are many connected environmental test devices, the operator does not need to check the data transmission harness 23 and the device interface 231 one by one. The operator can determine the connection status between the environmental test device and the corresponding protocol converter 12 simply by observing the illumination of the signal warning device 24. This reduces the difficulty of verifying the connection status and improves the verification efficiency. It also reduces the probability of data acquisition failure of some devices due to unstable or incorrect wiring during the data collection process.

[0034] In addition, this application provides some more specific implementation methods to improve the above-mentioned protocol conversion device.

[0035] Furthermore, the aforementioned wire harness receiver 22 includes an upper fixing plate 221, a lower fixing plate 222, a connecting plate 223, and a plurality of winding mechanisms 224. The upper fixing plate 221 is integrally formed with the lower fixing plate 222 by connecting plate 223, and a plurality of separation discs 225 are provided between the upper fixing plate 221 and the lower fixing plate 222. The separation discs 225 are spaced apart to form winding gaps. The plurality of winding mechanisms 224 correspond one-to-one with the winding gaps and are rotatably engaged with the separation discs 225 respectively. The aforementioned data transmission wire harness 23 is arranged to be stretched and wound in conjunction with the plurality of winding mechanisms 224. Specifically, the aforementioned winding mechanism 224 is a device in the prior art that can stretch and unwind the wire harness wound on the winding mechanism 224 during rotation or when the rotation stops. Its specific structure may include structural components and their connection and cooperation relationships in a charging cable with a detachable storage structure disclosed in Chinese Utility Model Publication No. CN220906838U, which can specifically implement functions or actions such as shrinking, stretching and locking the extension length of the cable.

[0036] Specifically, the aforementioned upper fixing plate 221 and an adjacent separating disc 225, any two adjacent separating discs 225, lower fixing plate 222 and an adjacent separating disc 225 are equivalent to multiple caps and bottom covers disclosed in the prior art, stacked from top to bottom. The aforementioned multiple data transmission harnesses 23 are equivalent to charging cable bodies disclosed in several prior art. The aforementioned multiple winding mechanisms 224 are equivalent to components or structures disclosed in several prior art, including outer shell, partition plate, limiting groove, winding drum, card slot, spring, etc., and their cooperative relationships. Among them, the cooperative relationship includes, but is not limited to, the aforementioned prior art: the inner bottom of the outer shell is provided with The housing has a partition plate, and several limiting grooves are evenly spaced on the inner bottom of the outer shell. The charging cable is positioned above the partition plate. A take-up drum is rotatably inserted into the top of the partition plate. A slot is formed on the top of the take-up drum corresponding to the charging cable. Through slots are formed on the side walls on both sides of the top of the outer shell corresponding to the charging cable. The charging cable is located inside the slot. A spring is fixedly connected to the outer wall of the take-up drum at one end that passes through the partition plate. The spring is located at the inner bottom of the outer shell, and the end of the spring away from the take-up drum is fixedly connected to the inner wall of the outer shell. A bottom cover (either the aforementioned separation plate or the lower fixing plate) is provided below the spring.

[0037] When the data transmission harness 23 is needed, stretch the harness away from the housing. When the harness is stretched, it will drive the winding drum to rotate, thereby causing the spring to retract. After stretching, connect the device interface 231 to the environmental testing equipment. When the harness needs to be stored, unplug the device interface, and the winding drum will rewind the harness under the action of the spring.

[0038] When using the above-mentioned protocol conversion device, the operator can stretch the data transmission harness 23 that matches the environmental testing equipment to a certain length and then plug its device interface 231 end into the data acquisition interface of the environmental testing equipment. Since different data transmission harnesses 23 that can match the output protocol of the environmental testing equipment are wound and arranged at different winding gaps on the same harness receiver 22, the above-mentioned protocol conversion device can simultaneously convert the data of multiple environmental testing equipment. This not only improves the conversion efficiency, but also facilitates the storage and management of multiple data transmission harnesses 23, avoiding the cross-entanglement of harnesses connecting multiple devices, which would cause a messy laboratory site. This makes it easier for the safety and cleanliness of the experimental site to meet the standards.

[0039] Furthermore, to improve the smoothness of the data transmission harness 23 during the stretching or retraction process, the number of the connecting plates 223 is a pair. The pair of connecting plates 223 are symmetrically distributed on both sides of the upper fixed plate 221 and the lower fixed plate 222 in the vertical direction and are connected to the upper fixed plate 221, the lower fixed plate 222 and each separation disc 225 to form an integral unit. A guide hole 2231 is provided on one side of the connecting plate 223 at a position opposite to the winding gap. Specifically, the extension direction of the guide hole 2231 is tangent to the direction of the data transmission harness 23 winding around the winding mechanism 224, and the guide holes 2231 on the two connecting plates 223 are centrally symmetrically arranged relative to the winding axis of the data transmission harness 23. The guide holes 2231 are all connected to the winding gap. The two ends of the data transmission harness 23 pass through the two guide holes 2231 that are connected to the winding gap corresponding to the data transmission harness 23.

[0040] When using the above-mentioned protocol conversion device, the data transmission harness 23 can be stretched or retracted along the guide hole 2231 and wound onto the winding mechanism 224, which can effectively improve the smoothness of the harness being stretched and retracted, and prevent the harness from getting stuck or coming off the winding mechanism 224.

[0041] To fully improve protocol conversion efficiency, there are two wire harness organizers 22, which are distributed left and right and spaced apart in the second housing 21. The total number of data output interfaces 211 is the same as the number of winding gaps, and the multiple data output interfaces 211 are arranged in two columns along the vertical direction and are distributed corresponding to the winding gaps.

[0042] Specifically, when two wire harness retractors 22 are set, it means that the above-mentioned device connection module 20 can interconnect with environmental test equipment with up to twice the number of winding gaps. Since multiple data transmission wire harnesses 23 are distributed in two columns along the vertical direction, an equal number of data output interfaces 211 need to be set to connect to the corresponding data transmission wire harnesses 23. In order to ensure the smooth stretching and retraction of the data transmission wire harnesses 23, the above-mentioned data output interfaces 211 must be distributed corresponding to the winding gaps of each data transmission wire harness 23 and be on the same horizontal plane, so as to save the length of the connection section between the data transmission wire harnesses 23 and the data output interfaces 211, and ensure that the data transmission wire harnesses 23 have sufficient length redundancy to establish interconnection with environmental test equipment that is far away.

[0043] Simultaneously, in order to enable the aforementioned data output interface 211 to be plugged into the corresponding data input interface 111 to achieve protocol conversion, the number of data input interfaces 111 on the surface of the aforementioned first housing 11 is the same as the number of the aforementioned data output interfaces 211, and the arrangement of the multiple data input interfaces 111 is the same as the arrangement of the multiple data output interfaces 211 (meaning that the spacing between each data output interface 211, the arrangement direction, and the number of each row and column are the same as the spacing between each data input interface 111, the arrangement direction, and the number of each row and column).

[0044] Furthermore, a large number of data output interfaces 211 may cause inconvenience for the operator when connecting the first housing 11 and the second housing 21. To prevent the data output interface 211 from not being properly connected to the data input interface 111, the surface of the first housing 11 is provided with a connection guide module 13, and the surface of the second housing 21 is provided with a connection guide module 25. Specifically, the connection guide module 13 includes at least two baffles 131, which are arranged in a semi-enclosed structure around the data input interface 111, and the baffles 131 intersect at the lower side of the data input interface 111 to form a limiting corner; the connection guide module 25 includes a limiting frame 251 and at least a pair of elastic telescopic rods 252. The limiting frame 251 is slidably connected to the data output interface 211 through a central through-hole, and the limiting frame 251 is connected to the second housing 21 through a pair of elastic telescopic rods 252.

[0045] Specifically, at least a portion of the outer contour of the limiting frame 251 is engaged with the limiting corner. When the first box 11 and the second box 21 need to be connected, the limiting frame 251 at each data output interface 211 is overlapped on the upper surface of the baffle 131 located below the data input interface 111, and the second box 21 is pushed in the direction of the other baffle 131, so that the limiting frame 251 moves to the intersection of the two baffles 131 and is engaged with the limiting corner. At this time, it can be ensured that each data output interface 211 is horizontally aligned with the data input interface 111. Then, the second box 21 is pushed towards the first box 11, so that each data output interface 211 is inserted into the data input interface 111 to establish interconnection. During the insertion process, the limiting frame 251 slides in the opposite direction of the movement of the data output interface 211 under the contraction of the elastic telescopic rod 252, so that the data output interface 211 passes through the irregular hole of the limiting frame 251 and is inserted into the data input interface 111.

[0046] In a preferred embodiment, the number of baffles 131 is three. The three baffles 131 are arranged in a semi-enclosed structure around the data input interface 111 and are connected to form a guide groove with an opening on one side. The inner width d of the guide groove is not less than the outer width h of the limiting frame 251. Specifically, compared with a limiting angle formed by two baffles 131, the guide groove formed by three baffles 131 can prevent the limiting frame 251 from shifting vertically during movement, so that the limiting frame 251 can quickly and accurately align the data output interface 211 with the data input interface 111 during sliding, further improving the insertion success rate and interconnection efficiency.

[0047] Furthermore, a storage groove 212 is provided on the surface of the second box 21 around the data output interface 211. A mounting hole 213 is provided in the storage groove 212 along the depth direction. One end of the elastic telescopic rod 252 is fixed to the bottom of the mounting hole 213, and the other end is connected to the limiting frame 251. The elastic telescopic rod 252 is used to move the limiting frame 251 into the storage groove 212.

[0048] Specifically, the shape of the storage groove 212 matches the outline shape of the limiting frame 251, and the depth of the storage groove 212 is not less than the thickness of the limiting frame 251. The elastic telescopic rod 252 includes a spring, a sleeve rod, and an extension rod. The sleeve rod is fitted into the mounting hole 213, the spring is set inside the sleeve rod, one end of the extension rod can slide inside the sleeve rod and abut against the spring, and the other end protrudes outside the sleeve rod and is connected to the limiting frame 251. During the insertion process of the data output port and the data input port, as the elastic telescopic rod 252 is continuously compressed, the limiting frame 251 enters the storage slot 212, and its side away from the second box 21 is flush with the surface of the second box 21 where the data output interface 211 is located. This allows the data output interface 211 in the limiting frame 251 to fully extend and insert into the data input interface 111, thereby avoiding the situation where the insertion is not in place. When it is necessary to release the insertion state, it is only necessary to disconnect the connection between the first box 11 and the second box 21. Under the elastic force of the elastic telescopic rod 252, the limiting frame 251 can be pushed to move, so that the operator can separate the data output interface 211 and the data input interface 111 without the need for force or with little force.

[0049] Furthermore, to ensure a secure connection between the data output interface 211 and the data input interface 111, preventing disengagement due to external forces, the surface of the first housing 11 is provided with a plurality of first alignment blocks 112, and the second housing 21 is provided with a plurality of second alignment blocks 214 relative to the first alignment blocks 112. The second alignment blocks 214 and the first alignment blocks 112 are provided with screw holes respectively. By tightening the first alignment blocks 112 and the second alignment blocks 214 with bolts, the first housing 11 and the second housing 21 can be connected as one unit, thereby ensuring that the data output interface 211 remains inserted into the data input interface 111.

[0050] Furthermore, the surface of the first housing 11 is provided with a heat dissipation window 113, which is composed of a plurality of heat dissipation holes arranged in an array, for communicating between the inside and outside of the first housing 11, thereby dissipating the heat generated by the protocol converter 12.

[0051] Combining the various structures and features in the above embodiments, the above protocol conversion device can improve the portability of interconnection and protocol conversion with environmental testing equipment, laying a reliable foundation for data protocol conversion of environmental testing equipment and for achieving data analysis, status monitoring and other purposes.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
