[0034] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0036] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0037] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0038] This technical solution proposes a linear temperature sensing device, including: a relay module 100 for electrical connection to a host; a first temperature sensing cable 210, one end of which is electrically connected to the relay module 100; and a first temperature sensing element 220, which is plugged into and electrically connected to the end of the first temperature sensing cable 210 away from the relay module 100. Both the first temperature sensing cable 210 and the first temperature sensing element 220 are used to sense the ambient temperature.

[0039] In the technical solution of this utility model, the relay module 100 is used to transmit the electrical signals of the first temperature sensing cable 210 and the first temperature sensing element 220 to the relay module 100 to determine the ambient temperature. In addition, in this solution, both the first temperature sensing cable 210 and the first temperature sensing element 220 can be used to detect temperature. They can detect the temperature at different locations or the temperature at the same location to verify the accuracy of the detection results. Furthermore, the first temperature sensing cable 210 and the first temperature sensing element 220 are connected by a plug-in method, and the user can use the first temperature sensing cable 210 alone or both at the same time as needed, which improves the flexibility of use.

[0040] The relay module 100 receives electrical signals from the first temperature-sensing cable 210 and the first temperature-sensing element 220, and transmits these signals to the host computer for processing to obtain temperature data. The first temperature-sensing cable 210 can utilize the thermocouple principle, and may contain two core wires with temperature-sensing material on the outside. The impedance between the core wires changes with the ambient temperature. The host computer measures the ambient temperature by detecting the impedance of the first temperature-sensing cable 210. One end of the first temperature-sensing cable 210 is electrically connected to the signal processing module, serving as a temperature signal transmission channel, transmitting its own electrical signal to the relay module 100. Additionally, a standardized plug can be installed at the end of the first temperature sensing cable 210 away from the relay module 100. The first plug can be inserted into the plug. The first temperature sensing element 220 can be selected from different types according to actual needs, such as thermistors, thermocouples, or semiconductor temperature sensors. The electrical signal of the first temperature sensing element 220 can be transmitted to the relay module 100 through the first temperature sensing cable 210 to obtain the temperature at the location of the first temperature sensing element 220. The plug-in design of the first temperature sensing cable 210 and the first temperature sensing element 220 is not only convenient to install and easy to operate, but also allows users to flexibly choose whether to use the first temperature sensing element 220 according to actual needs. When temperature monitoring is required at different locations, the first temperature sensing element 220 and the first temperature sensing cable 210 can be placed at different locations. When dual detection is required at the same location, the first temperature sensing element 220 can be inserted into the end of the first temperature sensing cable 210, and both can be placed at the same location to achieve mutual verification and comparison of temperature data. When the detection results do not need to be particularly accurate, the first temperature sensing element 220 can be removed, and only the first temperature sensing cable 210 can be used for measurement. The above design can improve the flexibility of use and expand the application scenarios.

[0041] like Figure 1 and Figure 2In one embodiment of this utility model, a first temperature-sensing cable 210 is provided with a first terminal, a first temperature-sensing element 220 is provided with a socket, and a second terminal is provided in the socket. The first terminal and the second terminal are plugged in and electrically connected. The linear temperature sensing device also includes a snap-fit ​​structure 300, which is located at the socket and snaps into the first temperature-sensing cable 210. Specifically, a first terminal is provided at one end of the first temperature-sensing cable 210. The first terminal can be made of copper alloy material and has a columnar structure. The second terminal is a hollow cylindrical structure, also made of copper alloy material. When the first terminal is inserted into the second terminal, the two fit tightly together to form a stable electrical connection. In addition, to enhance the stability of the connection, the linear temperature sensing device also provides a snap-fit ​​structure 300, which is located at the socket and snaps into the first temperature-sensing cable 210. The snap-fit ​​structure 300 can be a claw or similar device. When the socket of the first temperature sensing element 220 is fitted onto the first temperature sensing cable 210, the claw will elastically deform and clamp onto the side wall of the first temperature sensing cable 210, thereby achieving the snap-fit ​​connection between the first temperature sensing element 220 and the first temperature sensing cable 210. This improves the mechanical strength of the connection between the first temperature sensing cable 210 and the first temperature sensing element 220, ensuring stable operation for a long time in complex field environments and guaranteeing the stability of the electrical connection. In addition, users can easily disassemble and reinstall the first temperature sensing element 220, facilitating maintenance and replacement.

[0042] Figure 3 One structural form of the snap-fit ​​structure 300 is shown, in which the snap-fit ​​structure 300 includes:

[0043] The claw component 310 is disposed in the insertion hole and is used to engage with the first temperature sensing cable 210.

[0044] Fastener 320 is located around the periphery of the socket, with one end of fastener 320 extending into the socket and abutting against the claw 310.

[0045] During assembly, the claw component 310 and the fastener 320 are sequentially inserted. In use, the first temperature-sensing cable 210 is inserted starting from the fastener 320, passing through the claw component 310, and finally the first terminal of the first temperature-sensing cable 210 is connected to the second terminal. During the insertion of the first temperature-sensing cable 210, the claw component 310 deforms and tilts, contacting the outer wall of the first temperature-sensing cable 210. The claw component 310 is tilted towards the second terminal, ensuring that the first temperature-sensing cable 210 can only move forward and not backward, maintaining a sealed fit after contact with the sealing element. When it is necessary to disassemble the first temperature-sensing cable 210, the fastener 320 is pressed, causing it to abut against the claw component 310, further deforming it and disengaging it from the outer wall of the first temperature-sensing cable 210, at which point the first temperature-sensing cable 210 can be pulled out. This structure facilitates the assembly and disassembly of the first temperature-sensing cable 210, improving its flexibility of use.

[0046] like Figure 1 As shown, in another embodiment of this utility model, the linear temperature sensing device further includes a second temperature sensing component 400. The second temperature sensing component 400 is plugged into and electrically connected to the first temperature sensing element 220, and is used to sense the ambient temperature. The second temperature sensing component 400 can adopt the same structure as the first temperature sensing component 200. The second temperature sensing component 400 can be a thermal cable, a thermistor, a thermocouple, or a semiconductor temperature sensor, etc. The second temperature sensing component 400 has a plug, and the first temperature sensing element 220 has a corresponding socket. The plug and socket are connected, and a wire is provided on the socket to connect to the first temperature sensing cable 210, so that the temperature signal measured by the second temperature sensing component 400 is transmitted to the relay module 100. By adding the second temperature sensing component 400, the linear temperature sensing device can achieve multi-point monitoring of the ambient temperature and obtain more comprehensive temperature information. At the same time, the host can perform fusion processing based on the temperature data measured by different components, further improving the measurement accuracy and reliability. Furthermore, the second temperature sensing component 400 is redundant with the first temperature sensing component 200. When one component fails, the other component can still continue to work, ensuring the continuity of temperature monitoring, effectively reducing the risk of system failure, and improving the reliability of the sensor in critical applications.

[0047] like Figure 1 As shown, in one embodiment of this utility model, the second temperature sensing component 400 includes:

[0048] The second temperature sensing cable 410 has one end plugged into and electrically connected to the first temperature sensing element 220;

[0049] The second temperature sensing element 420 is plugged into and electrically connected to the end of the second temperature sensing cable 410 that is away from the first temperature sensing element 220.

[0050] The second temperature-sensing cable 410 can adopt the same structure as the first temperature-sensing cable 210, which will not be described in detail here. One end of the second temperature-sensing cable 410 can be provided with a terminal similar to the first terminal, while the first temperature-sensing element 220 is provided with a terminal similar to the second terminal. The second temperature-sensing cable 410 is plugged into the first temperature-sensing element 220, and the temperature signal is transmitted to the relay module 100 through the first temperature-sensing element 220 and the first temperature-sensing cable 210. The second temperature-sensing element 420 is similar to the first temperature-sensing element 220, and can be selected as a thermistor, thermocouple or semiconductor temperature sensor according to actual needs. The second temperature sensing cable 410 is plugged into and electrically connected to the first temperature sensing element 220. The plugging structure between the second temperature sensing cable 410 and the second temperature sensing element 420 is the same as that between the first temperature sensing cable 210 and the first temperature sensing element 220, and will not be described in detail here. By adding the second temperature sensing component 400, the sensor can cover a wider monitoring area and obtain more comprehensive temperature information. In addition, the second temperature sensing component 400 adopts a detachable connection method, and users can flexibly choose whether to install the second temperature sensing component 400 according to actual needs, so as to realize the flexible expansion of the system.

[0051] like Figure 1 As shown, in one embodiment of this utility model, multiple second temperature sensing components 400 are provided. In each second temperature sensing component 400, one end of the second temperature sensing cable 410 is plugged into the second temperature sensing element 420, and the other end is plugged into another second temperature sensing component 400. The multiple second temperature sensing components 400 are interconnected in a cascaded manner to form a monitoring link. The second temperature sensing cable 410 in each second temperature sensing component 400 not only connects to its own second temperature sensing element 420, but also transmits signals to adjacent second temperature sensing components 400. This allows the linear temperature sensing device to cover a longer monitoring distance or a wider area, expanding its application scenarios. Furthermore, users can flexibly adjust the number of second temperature sensing components 400 according to actual monitoring needs, improving scalability and adaptability, and making subsequent maintenance and replacement more convenient.

[0052] like Figure 5 As shown, in one embodiment of this utility model, the first temperature sensing cable 210 includes:

[0053] First insulating sleeve 211;

[0054] Signal line 212 is inserted inside the first insulating sleeve 211. One end of signal line 212 is electrically connected to the relay module 100, and the other end is electrically connected to the first temperature sensing cable 210.

[0055] Two second insulating sleeves 213 are provided, and the two second insulating sleeves 213 surround and cover the outside of the first insulating sleeve 211.

[0056] Temperature measuring wire 214: A set of temperature measuring wires 214 is provided in each second insulating sleeve 213. One end of the temperature measuring wire 214 is electrically connected to the relay module 100, and the other end is electrically connected to the first temperature sensing cable 210.

[0057] The first insulating sleeve 211 is the basic structure of the first temperature-sensing cable 210. Made of insulating material, it provides protection and support for the internal signal line 212, ensuring the stability and reliability of signal transmission. The signal line 212 passes through the first insulating sleeve 211 and consists of two strands. One end of the signal line 212 is electrically connected to the relay module 100, and the other end is electrically connected to the first temperature-sensing element 220, responsible for transmitting the temperature signal detected by the first temperature-sensing element 220 to the relay module 100. Two second insulating sleeves 213 are provided, located on either side of the first insulating sleeve 211. Made of the same insulating material as the first insulating sleeve 211, the two second insulating sleeves 213 surround and cover the outside of the first insulating sleeve 211, forming... Figure 5 The double-layer structure shown further enhances the anti-interference capability of the signal line 212. A set of temperature sensing wires 214 is installed within each second insulating sleeve 213. These temperature sensing wires 214 also use multi-strand twisted wires. The two signal lines 212 are externally coated with temperature-sensitive material, and the impedance between the signal lines 212 changes with the surrounding temperature. One end of the temperature sensing wire 214 is electrically connected to the relay module 100, and the other end is electrically connected to the first temperature sensing element 220. This multi-layer structure improves the mechanical strength and anti-interference capability of the first temperature sensing cable 210. Furthermore, the two sets of temperature sensing wires can simultaneously measure two temperature signals, improving the detection accuracy of the first temperature sensing cable 210.

[0058] like Figure 5As shown, in one embodiment of this utility model, one of the two second insulating sleeves 213 has a protruding locking body 215 on its side wall, and the other has a recessed locking groove 216 on its side wall. The locking body 215 and the locking groove 216 extend along the length direction of the first temperature-sensing cable 210, and the locking body 215 and the locking groove 216 are engaged. The locking body 215 can be integrally formed on the side wall of one of the second insulating sleeves 213. The locking body 215 has a protruding structure with a trapezoidal cross-section, narrower at the root and wider at the end. The locking groove 216 is correspondingly disposed on the side wall of the other second insulating sleeve 213, and its shape matches the locking body 215. Both the locking body 215 and the locking groove 216 extend along the length direction of the second insulating sleeve 213. When assembling the first temperature-sensing cable 210, the two second insulating sleeves 213 are respectively fitted onto both sides of the first insulating sleeve 211, and then the locking bodies 215 and the locking grooves 216 are aligned. The card body 215 is gradually inserted into the card slot 216. During the insertion process, the elastic deformation of the card body 215 allows it to pass smoothly through the opening of the card slot 216. When the card body 215 is fully inserted into the card slot 216, its elastic restoring force makes it fit tightly inside the card slot 216, forming a stable engagement. The design of the card body 215 and the card slot 216 makes the installation and removal of the second insulating sleeve 213 quick and easy, greatly improving maintenance efficiency and reducing maintenance costs. In addition, users can also replace different temperature sensing wires according to their needs to meet various usage scenarios.

[0059] like Figure 4 As shown, in another embodiment of this utility model, the linear temperature sensing device further includes a magnet 500, which is sleeved on the outside of the first temperature sensing cable 210. The magnet 500 allows the linear temperature sensing device to be easily adsorbed and fixed on metal surfaces, such as pipes, equipment housings, and metal components, improving installation efficiency and flexibility.

[0060] In another embodiment of this utility model, multiple first temperature sensing components 200 are provided, and each of the multiple first temperature sensing components 200 is electrically connected to the relay module 100. In this solution, the multiple first temperature sensing components 200 are distributed along different locations in the monitoring area; for example, in an industrial plant, multiple first temperature sensing components 200 can be arranged around key equipment, along pipelines, in storage areas, etc., according to the layout of production equipment and temperature monitoring requirements, to achieve comprehensive temperature monitoring coverage; by setting multiple first temperature sensing components 200, the ambient temperature at different locations can be monitored simultaneously, obtaining more comprehensive temperature data, which is beneficial to improving monitoring capabilities.
