[0002] As energy storage projects expand in scale, evolving from MWh to GWh power stations, the temperature changes of various components in energy storage systems and packs during the charging and discharging process are a key concern. Traditional temperature monitoring methods typically use temperature data loggers to extend temperature acquisition lines to collect temperature data. Wireless temperature sensors released by various manufacturers also typically connect one acquisition point to one temperature sensor. This method requires a long time to set up temperature points, involves numerous wiring harnesses, and presents numerous test anomalies, making troubleshooting difficult and posing significant challenges to testing.

[0003] Existing temperature monitoring methods mostly use temperature acquisition lines plus temperature data recorders to record temperature. When there are many collection quantities and the collection locations are not concentrated, the temperature acquisition lines will become too long and tangled, which greatly prolongs normal working time.

[0012] Furthermore, the temperature measurement module has a shell, and a plurality of the second slots are evenly spaced apart and arranged on a side surface of the shell.

[0013] Furthermore, the plurality of temperature sensors include one or more of scissor-type temperature sensors, magnetic temperature sensors and adsorption temperature sensors.

The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0035] The following is attached with the instruction manual Figure 1 To the attached Figure 7 , the wireless temperature measuring device of the present utility model is introduced.

[0036] In one embodiment, Figure 1 、 Figure 2 and Figure 3 As shown, the wireless temperature measuring device includes a temperature measuring module 100, a plurality of temperature measuring sensors 200 and a plurality of temperature collecting line units 300 that can be electrically connected to each other for extension.

[0037] The number of the temperature collection line units 300 is greater than the number of the temperature measurement sensors 200 .

[0038] The temperature measurement sensor 200 is electrically connected to the temperature measurement module 100 through the temperature acquisition line unit 300 to form a plurality of temperature measurement channels.

[0039] The temperature measurement module 100 includes a data acquisition module and a wireless module 110 . The data acquisition module is used to receive temperature data of the plurality of temperature measurement channels, and the wireless module 110 is used to send the temperature data to an external module.

[0040] During use, the wireless temperature measurement device of this embodiment is moved near a battery pack or other device to be measured. Then, depending on the distance between each test point and the temperature measurement module 100, different numbers of temperature acquisition lines are selected and electrically connected to each other and extended to form a temperature acquisition line of appropriate length, thereby connecting the temperature sensor 200 at the test point to the temperature measurement module 100. For example, for a closer test point, only one temperature acquisition line unit 300 may be used. For a farther test point, multiple (e.g., two, three, or other numbers) temperature acquisition line units 300 may be electrically connected to each other and extended, depending on the specific distance, to connect the temperature sensor 200 at the current test point to the temperature measurement module 100. The wireless temperature measurement device of this embodiment can support temperature acquisition at multiple temperature measurement points and can configure different numbers of temperature acquisition line units 300 according to the specific distance. Furthermore, because the wireless module 110 is used for data transmission, the temperature acquisition lines are less likely to become too long or tangled.

[0041] In one embodiment, Figure 2 and Figure 3 As shown, in order to enable two temperature acquisition line units 300 to be connected to each other, each temperature acquisition line unit 300 has a first connector 310 and a second connector 320. The first connector 310 and the second connector 320 of different temperature acquisition line units 300 are adapted. When in use, multiple temperature acquisition line units 300 can be combined into temperature acquisition lines of different lengths by interconnecting according to specific needs for signal transmission. This meets the transmission requirements of different distances while preventing a single line temperature acquisition line from being too long.

[0042] In one embodiment, Figure 1As shown, in order to enable the temperature sensor and the temperature measurement module 100 to be compatible with the temperature acquisition line unit 300, the temperature measurement sensor 200 has a first slot for adapting to the first connector 310, and the temperature measurement module 100 has a second slot 120 for adapting to the second connector 320. The number of the second slots 120 is the same as the number of the temperature measurement sensors 200. For example, in this embodiment, the temperature measurement module 100 supports a maximum of 24 temperature measurement channels, each channel corresponding to one temperature measurement sensor 200. Therefore, the temperature measurement module 100 is provided with 24 second slots 120, corresponding to the configuration of 24 temperature measurement sensors 200.

[0043] In other embodiments, the number of the second fork grooves may also be different from the number of the temperature sensors 200 . For example, the number of the second fork grooves may be less than or greater than the number of the temperature sensors 200 .

[0044] In one embodiment, to properly arrange the second slots 120, the temperature measurement module 100 includes a housing, and multiple second slots 120 are evenly spaced apart on the side of the housing, thereby facilitating the insertion of the temperature acquisition line unit 300. The second slots 120 may be provided on only one side of the housing, or may be distributed on multiple sides of the housing.

[0045] In one embodiment, the plurality of temperature sensors 200 include one or more of a scissor-type temperature sensor 210 , a magnetic temperature sensor 220 , and an adsorption temperature sensor 230 .

[0046] For example, Figure 4 As shown, three types of temperature sensors are provided in this embodiment, and different temperature sensors 200 are suitable for different types of temperature measuring points. For example, the scissor-type temperature sensor 210 has a clamping claw that can be clamped at a thin-walled or plate-shaped temperature measuring point. For thin-walled or plate-shaped temperature measuring points, the scissor-type temperature sensor 210 can be used. The magnetic temperature sensor 220 has a magnet that can be adsorbed on the surface of a metal temperature measuring point. For a temperature measuring point with a metal surface, the magnetic temperature sensor 220 can be used. The adsorption temperature sensor 230 has a suction cup that can be adsorbed on a smooth surface. For a temperature measuring point on a non-metallic surface, the adsorption temperature sensor 230 can be used.

[0047] In other embodiments, only one or two types of temperature measuring sensors may be provided. Of course, other types of temperature measuring sensors may also be provided as required.

[0048] In one embodiment, Figure 1As shown, in order to promptly detect abnormal temperature measurement points, the temperature measurement module 100 also includes an alarm. When the temperature data of any of the temperature measurement channels is outside the preset temperature range, the alarm will sound an alarm, indicating that the temperature of the temperature measurement channel is abnormal, so as to remind the temperature measurement personnel to take timely action. Preferably, the alarm is a buzzer 140, of course, other types of alarms can also be used.

[0049] In one embodiment, the temperature measurement module 100 further includes a display screen 130, and the display screen 130 is used to display the temperature data of the plurality of temperature measurement channels.

[0050] In one embodiment, in order to process the temperature data in a timely manner, Figure 4 and Figure 7 As shown, the temperature measurement module 100 also includes a processor, and the data acquisition module is an analog-to-digital converter (i.e., ADC). The analog-to-digital converter is used to convert the analog signal representing the temperature data into a digital signal and transmit it to the processor. The processor is electrically connected to the display screen 130 so that the display screen 130 displays the temperature data.

[0051] Preferably, the processor is a microprocessor (MCU), but other types of processors may also be used.

[0052] Preferably, the display screen 130 is an industrial-grade resistance display screen 130, which has strong anti-interference ability and can display the temperature data collected by each channel in real time. Figure 5 and Figure 6 As shown, the MCU is provided with a temperature alarm threshold and a corresponding measured temperature value. When the temperature data exceeds the preset temperature alarm threshold, the measured temperature value of the channel is highlighted on the display screen 130 to indicate the temperature abnormality, and the buzzer 140 is triggered to alarm. Each channel has an alarm temperature value and is configured for channel usage. It can be disabled when not in use.

[0053] In this embodiment, if Figure 7 As shown, the temperature measurement module 100 has an acquisition rate of once every 1 second. After measuring the temperature data, the analog signal is converted into a digital signal through the analog-to-digital converter and transmitted to the MCU for processing to obtain the currently acquired temperature data. This temperature data can be displayed in real time on the display screen 130, or the temperature data can be centrally sent to an external data control center via the wireless module 110 every 5 seconds. In addition, after collecting the temperature data of each temperature measurement point, the analog-to-digital converter also filters the temperature measurement data to ensure the accuracy of the data.

[0054] When in use, one temperature measurement module 100 can be used alone, or multiple temperature measurement modules 100 can be used simultaneously, and can be flexibly configured according to the number of temperature collection points.

[0055] In one embodiment, the temperature measurement module 100 further includes a power supply, which is used to supply power to the temperature measurement module 100 and the temperature measurement sensor 200. The power supply supports two modes: external power supply and battery power supply to adapt to application modes in different scenarios.

[0056] In one embodiment, in order to send the temperature data to the data transmission center by wireless transmission, the wireless module 110 is an antenna arranged on the side of the shell. The antenna supports different communication methods such as 5G, WIFI, Bluetooth, Zigbee (a low-speed, short-distance transmission wireless network protocol), and communicates with the control center through a specific wireless communication protocol to realize real-time transmission of temperature data. The control center can collect the temperature data of each temperature measurement module 100 and has display, data analysis, data storage, data reporting, and data visualization functions.
