[0022] The embodiments of the present application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar modules or modules with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application. On the contrary, the embodiments of the present application include all changes, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0023] In order to monitor the height changes of battery poles and improve the safety and operation and maintenance efficiency of batteries, an embodiment of the present application proposes a battery pole height monitoring device.

[0024] Please refer to Figure 1 The battery pole height monitoring device includes a non-contact displacement sensor, a temperature sensor, and a data acquisition module, a data processing module, and a power supply module integrated into a system integration device.

[0025] The non-contact displacement sensor is positioned above the battery, primarily for real-time measurement of the height of the top of the battery pole. In one embodiment, the non-contact displacement sensor can be implemented using a laser displacement sensor or an ultrasonic sensor to ensure accurate and reliable measurement. Preferably, a non-contact displacement sensor is positioned above each battery pole.

[0026] The temperature sensor can be set close to the battery and is mainly used to monitor the ambient temperature of the battery.

[0027] The system integration device is mainly used to obtain data from non-contact displacement sensors and temperature sensors to complete the calculation of the displacement changes of the battery poles.

[0028] Specifically, the system integration device includes a data acquisition module, a data processing module, and a power supply module, which cooperate to complete data collection and processing. The data acquisition module is connected to the non-contact displacement sensor and temperature sensor, and collects the measurement data of the two sensors in real time. Since the sensor outputs an analog signal, the data acquisition module also converts the collected analog signal into a digital signal. The data processing module calculates the change in battery pole height based on the digital signal converted by the data acquisition module. In this embodiment, the calculation of the change in battery pole height is compensated by using ambient temperature data. The power supply module provides power to the non-contact displacement sensor, temperature sensor, data acquisition module, and data processing module.

[0029] In one embodiment, the system integration device further includes an alarm module that can trigger an alarm signal when the calculated change in battery pole height exceeds a preset threshold. Preferably, the alarm signal is sent to maintenance personnel via an LED indicator, a buzzer, or a network notification.

[0030] In one embodiment, multiple alarm thresholds can be set to provide graded early warnings. For example, a Level 1 alarm: a battery pole height change of ΔH > 2mm (minor abnormality). A Level 2 alarm: a battery pole height change of ΔH > 5mm (serious fault). Alarm signals are sent to maintenance personnel via LED indicators, a buzzer, or a network notification.

[0031] In order to provide data traceability function, the system integration device also includes a data tracing module, which stores the collection time, battery pole height, temperature and pole change, supports data query and trend analysis, and provides data visualization function.

[0032] Furthermore, this embodiment also provides a specific process for the data processing module to calculate the battery pole height in real time, as follows: The system obtains N consecutive battery pole height values ​​collected during installation and calculates the average to obtain the initial battery pole height. It also obtains the real-time battery pole height and ambient temperature, and uses the ambient temperature to compensate for changes in the ambient temperature to obtain the temperature-compensated battery pole height. The system determines the change in battery pole height based on the temperature-compensated height and the initial battery pole height. If the change in battery pole height exceeds a preset threshold, the system directly controls the alarm module to issue an alarm signal.

[0033] In order to more clearly illustrate the working process of the battery pole height monitoring proposed by the present invention, an embodiment of the present invention also provides a battery pole height monitoring method, which specifically includes: Step S1: Install a non-contact displacement sensor above the battery and install a temperature sensor in the environment where the battery is located; Step S2: using a non-contact displacement sensor to collect N battery pole height values, and taking the average of the N collected results as the initial battery pole height value, and setting a reference temperature; Step S3: obtaining the battery pole height value and the current ambient temperature through the data acquisition module, and compensating the acquired battery pole height value using the ambient temperature to obtain a compensated battery pole height value; Step S4: Compare the compensated battery pole height value with the initial battery pole height value to obtain a pole height change.

[0034] In step S2, the data acquisition module collects the battery pole height value and the current ambient temperature according to a preset data acquisition frequency. In one embodiment, the preset data acquisition frequency can be set to once per hour.

[0035] At the same time, in step S2, the calculation formula for the initial height of the battery pole is as follows:

[0036] in, is the initial height, is the sampling value for each time, This method can dynamically adjust the benchmark.

[0037] In step S3, the specific method of compensating the collected battery pole height value using the ambient temperature is as follows:

[0038] in, Compensate pole height for ambient temperature changes, is the current ambient temperature pole height, is the thermal expansion coefficient, which is set during initialization; is the reference temperature, The current collected ambient temperature.

[0039] In step S4, the compensation of the pole height change is completed. calculate:

[0040] According to the calculated change in pole height The system then triggers an alarm. If the post-compensation pole height change, ∆H, exceeds the preset alarm threshold, ∆Hmax (this threshold is adjustable), an audible and visual alarm is triggered. For example, a Level 1 alarm: ∆H > 2mm (minor abnormality). A Level 2 alarm: ∆H > 5mm (serious fault). The alarm signal is sent to maintenance personnel via an LED indicator, buzzer, or network notification.

[0041] The battery pole height monitoring method proposed in the present invention can monitor pole height changes in real time, dynamically adjust the reference height, and take temperature influence into account to achieve high-precision real-time monitoring and graded early warning of pole corrosion, loosening or deformation, thereby improving battery safety and operation and maintenance efficiency.

[0042] In practical applications, batteries are often grouped together in a battery pack. To address this scenario, the number of contactless distance sensors can be increased to measure the height of each battery post. Simultaneously, the data acquisition module records the height measurement for each battery post. The temperature sensor can be shared across a battery pack. The subsequent data processing module calculates the change in height of each battery post, enabling simultaneous measurement of all batteries in the pack and implementing an alarm for abnormal post heights for one or more batteries.

[0043] In some embodiments, if there are multiple battery packs, when increasing the number of non-contact distance sensors to measure the height of each battery pole, in order to increase the temperature measurement accuracy, a corresponding temperature sensor can be set for each battery pack to complete the ambient temperature measurement of the corresponding battery pack.
