Description

Technical Field

[0001] This invention belongs to the field of temperature detection technology, and in particular relates to a multi-point measurement distributed temperature sensor. Background Technology

[0002] Traditional temperature monitoring mainly relies on a single-location temperature sensor or a small number of distributed temperature sensing devices. These methods have the following obvious limitations:

[0003] First, traditional single-point temperature sensors cannot provide comprehensive and accurate temperature distribution information, which is particularly insufficient in application scenarios that require temperature monitoring of a large area or multiple key points. Second, although early distributed temperature sensing systems could solve the above problems to some extent, they often faced issues such as unstable connections and inaccurate data transmission. Due to the lack of an effective physical locking mechanism, the connection between the sensor and the central processing unit was easily loosened or even detached due to external forces, resulting in data loss or transmission interruption, which increased maintenance costs and difficulties.

[0004] To address these issues, we provide a multi-point measurement distributed temperature sensor. Utility Model Content

[0025] Example

[0026] Please see Figure 1-4 This utility model is a multi-point measurement distributed temperature sensor, including a central processing unit 100 and several temperature sensing nodes 200 connected to the central processing unit 100. The central processing unit 100 includes a housing 101, an audible and visual alarm 102 fixed to the top of the housing 101, a micro display screen 103 embedded in the middle of the front of the housing 101, connection terminals 104 equidistantly arranged at the bottom of the housing 101, and indicator lights 105 corresponding to the connection terminals 104. The housing 101 serves as the main structure of the central processing unit 100, which not only protects the internal electronic components from physical damage and external environmental influences, but also provides a mounting base for each component. The micro display screen 103 allows users to directly view the data collected by each temperature sensing node 200, providing an intuitive way to understand the system status and changes in ambient temperature. When an abnormal temperature change is detected (such as exceeding the preset safety range), the audible and visual alarm 102 can quickly emit sound and light signals to promptly remind the user to take corresponding measures to prevent potential dangers. The connection terminals 104 are used for connecting each temperature sensing node 200.

[0027] The temperature sensing node 200 includes a kit 201 that is threadedly adapted to the connecting end 104, a terminal 202 connected to the other end of the kit 201, and a connecting line 203 for distributed connection of temperature sensors. The two ends of the kit 201 are adapted to the terminal 202 and the connecting end 104 respectively to ensure the connection stability and prevent them from falling off. Multiple temperature sensors are arranged in different positions via the connecting line 203 to cover a larger monitoring area and meet the needs of multi-point temperature monitoring.

[0028] Specifically, the lower front of the housing 101 is provided with a connection area 101c for mounting the connection terminal 104. The connection area 101c enables unified management of the connection terminal 104. The indicator light 105 is correspondingly located above the connection terminal 104 to display the working status of the connection terminal 104, such as whether the connection is successful or whether the data transmission is normal.

[0029] The connecting end 104 is threaded around its periphery and has a built-in metal end. The metal end is connected to the circuit board inside the housing 101 via a wire. The terminal 202 is inserted into the connecting end 104 and locked to the connecting end 104 by the kit 201. The terminal 202 completes the electrical connection by being inserted into the connecting end 104, while the kit 201 provides mechanical locking, increasing the reliability of the connection.

[0030] Furthermore, a back plate 106 is installed on the back of the housing 101, and a mounting member 107 is fixed at the middle position of the outer side of the back plate 106. The annular part of the mounting member 107 has positioning holes for external fastener installation. The back plate 106 is used to close the back of the central processing unit 100, while the mounting member 107 provides a convenient fixing method, so that the entire system can be stably installed on a wall or other supporting structure. A spare battery compartment is provided at the bottom inside the housing 101, and a cover plate 108 is provided on the outside of the spare battery compartment. The built-in spare battery provides additional power protection for the system, and can still maintain basic operation when the main power fails.

[0031] The housing 101 has heat dissipation areas 101a on both sides, which helps to improve air circulation inside the device and reduce the operating temperature. An interface 101b is embedded on one side of the upper end of the housing 101 for power connection, signal connection and data transmission of the central processing unit 100.

[0032] The operation process of this embodiment is as follows: First, the central processing unit 100 needs to be securely installed on the wall or other support structure through the mounting part 107, and fixed by external fasteners passing through the positioning holes of the mounting part 107. Then, open the cover plate 108 to check whether the backup battery in the backup battery compartment has been installed correctly, so as to ensure that the system can still maintain basic function operation when the main power fails.

[0033] Next, based on the actual needs of the monitoring area, select an appropriate number of temperature sensor nodes 200, and connect them to the connecting terminals 104 equidistantly located at the bottom of the central processing unit 100 via their kits 201 and threaded connections. Simultaneously, ensure that the wiring terminals 202 are inserted into the connecting terminals 104 and locked with the kits 201 to guarantee the stability of the electrical and mechanical connections. Each temperature sensor node 200 is arranged in different positions via connecting lines 203 to cover a larger monitoring area. After completing the hardware connection, turn on the power to the central processing unit 100. At this time, the micro-display 103 will display the data collected by each temperature sensor node 200, allowing the user to intuitively understand the system status and changes in ambient temperature.

[0034] When an abnormal temperature change is detected (exceeding the preset safety range), the audible and visual alarm 102 will quickly emit sound and light signals to remind the user to take timely measures to prevent potential dangers. In addition, the indicator lights 105 above each connection terminal 104 can help the user quickly determine the working status of the connection terminal 104, including whether the connection is successful and whether the data transmission is normal.

[0035] Throughout the operation, the heat dissipation zones 101a on both sides of the housing 101 help improve air circulation inside the equipment, reduce the operating temperature, and ensure stable operation of the system.
