Description

Technical Field

[0001] The present invention relates to the field of intelligent monitoring, and in particular to an intelligent monitoring system for predicting the battery life of a UPS. Background Art

[0002] Currently, important devices and equipment that need to be always in operation sometimes use UPS batteries in order to continue to supply power to the devices and equipment in the event of a power outage or a flashover.

[0003] UPS batteries are usually in a charged state and do not work (discharge) under normal circumstances. They will only work to supply power to the load in an emergency. However, UPS batteries will deteriorate over the years even when not working, and their lifespan will gradually shorten. In actual use, in order to avoid the risks brought by the UPS battery reaching its lifespan limit during use, users often abandon the UPS battery before it reaches the end of its lifespan, thereby greatly wasting resources. Therefore, it is very necessary to provide a UPS battery life monitoring system to provide users with the remaining service life of the UPS battery. However, there is no technology in the prior art that can effectively and accurately monitor the remaining service life of a UPS battery.

[0004] Chinese patent application number: CN113807000A discloses a method for predicting the remaining life of a UPS battery, especially a method based on data-driven, which includes collecting and recording the following project parameters as data, data cleaning, sampling from the data as training data, and the training method is a data-driven model of a neural network; at the same time, the training data is learned by a data encapsulator, and the learned data encapsulator calculates the confidence for each parameter record; the confidence represents the similarity between the data record and the data record from the training data; in step five, the corresponding confidence of the data encapsulator and the corresponding model error of the neural network are used to perform a weighted sampling, and after performing the spot sampling, a new part of the data records is obtained, which are now used for further learning of the data encapsulator and the neural network in the next iterative step, and the iterative learning of the data encapsulator or the neural network ends based on a suitable interruption criterion.

[0005] Chinese patent application number: CN105938183A discloses an intelligent monitoring system for predicting UPS battery life, including: an operation monitoring module, an operation analysis module and a display module; the operation monitoring module is used to monitor the operation status parameters of the uninterruptible power supply UPS battery in real time, and send the operation status parameters to the operation analysis module and the display module; the operation analysis module is used to calculate the remaining life of the UPS battery according to the operation status parameters of the UPS battery, and send the calculated remaining life of the UPS battery to the display module; the display module is used to display the operation status parameters and the remaining life of the UPS battery. This application can accurately and effectively estimate the remaining service life of the UPS battery, and can satisfy the user's convenience and direct acquisition of UPS battery performance parameter indicators.

[0006] However, the above method has the following problem: it is impossible to predict and display the remaining life of the UPS battery. Summary of the invention

[0007] To this end, the present invention provides an intelligent monitoring system for predicting the life of a UPS battery, so as to overcome the problem that the prior art cannot predict and display the remaining life of a UPS battery.

[0008] To achieve the above object, the present invention provides an intelligent monitoring system for predicting UPS battery life, comprising:

[0009] A battery pack, which is used to place a number of UPS batteries, and each UPS battery is connected in parallel with the rectifier;

[0010] A measuring group, connected to the battery group, for sensing rectification temperature information of the rectifier;

[0011] a processing group connected to the measuring group, for receiving the rectifier temperature information, filtering, generating corresponding filtering data, and outputting the corresponding remaining life information of the UPS battery,

[0012] Wherein, a conventional temperature range is set in the processing group, and the processing group filters the rectification temperature information that does not reach or exceeds the conventional temperature range, and generates corresponding filtering data;

[0013] A monitoring group, connected to the processing module, for determining the filtered data according to an interval threshold;

[0014] The regulating group is connected to the battery group, the processing group and the monitoring group, and is used to regulate the total charge and discharge power of each UPS battery and record the use time of each UPS battery.

[0015] Furthermore, the battery pack comprises:

[0016] The plurality of UPS batteries;

[0017] a rectifier connected to the UPS battery to rectify the output of the UPS battery;

[0018] A connector for connecting each UPS battery and the rectifier;

[0019] The regulating group is in the battery pack, and is arranged between the rectifier and the connector to control the charging and discharging of each UPS battery pack.

[0020] Furthermore, the battery pack further comprises:

[0023] Wherein, the positive electrode connector or the negative electrode connector is respectively connected to the connector;

[0024] When controlling the charge and discharge of a single UPS battery pack, the regulating group controls the charge and discharge of the corresponding UPS battery pack by regulating the on and off of the corresponding connector of the connector.

[0025] Furthermore, the measurement group includes:

[0026] a temperature sensor connected to the rectifier to sense the rectifier temperature information of the rectifier,

[0027] Wherein, the temperature sensor is fixed on the rectifier to sense the real-time temperature of the rectifier;

[0032] A display is connected to the monitoring group and is used to receive and display the instructions.

[0033] Furthermore, the monitoring group is provided with the interval threshold.

[0034] The interval threshold is the lower temperature limit and the upper temperature limit of the real-time temperature corresponding to the highest UPS battery conversion efficiency.

[0035] Further, the monitoring group receives the filtered data of the processing group and compares it with the interval threshold;

[0036] When the monitoring group determines that the filtered data is within the interval threshold, a health instruction is transmitted to the processing group. When the processing group receives the health instruction, the display responds to the health instruction and displays the battery life according to the maximum service life of the UPS.

[0037] Furthermore, when the monitoring group determines that the filtered data is less than or greater than the interval threshold, the adjustment group reduces the total charge and discharge power of the UPS battery.

[0038] Furthermore, when the monitoring group determines that the filtered data of the UPS battery is again less than or greater than the threshold, the adjustment group uses the battery usage time as the remaining battery life and transmits new remaining life information to the processing group. When the processing group receives the new remaining life information, the display shows the new remaining life information.

[0039] Furthermore, when the adjustment group completes the adjustment of the battery group, the display displays the remaining life information of each UPS battery group according to the new remaining life.

While effectively improving the service life of the UPS battery, the present invention can accurately estimate the remaining service life of the UPS battery. By using the above method, users can conveniently and directly monitor the performance parameter indicators of the UPS battery.

[0041] Furthermore, by providing a rectifier, conversion between DC and AC of the UPS battery can be achieved, which facilitates monitoring of the real-time temperature corresponding to the conversion efficiency of the UPS battery, and further improves the accuracy of estimating the remaining service life of the UPS battery.

[0042] Furthermore, by setting the input terminal, the output terminal, the positive electrode connection terminal and the negative electrode connection terminal, the UPS batteries can be connected in parallel, thereby improving the efficiency of UPS battery life detection.

[0043] Furthermore, by setting a temperature sensor, it is convenient to sense the rectifier temperature information of the rectifier in real time, which reduces the difficulty of monitoring the rectifier temperature and further facilitates users to monitor the performance parameter indicators of the UPS battery.

[0044] Furthermore, by clearing the rectifier temperature information that does not reach or exceeds the normal temperature range in the real-time rectifier temperature information and generating corresponding filtered data, the accuracy of UPS battery life monitoring is improved, and the interference of erroneous data on the monitoring results during the monitoring process is avoided.

[0045] Furthermore, by setting the interval threshold, the efficiency of UPS battery monitoring is improved, and the accuracy of UPS battery monitoring is further improved.

[0071] Each UPS battery has a positive terminal connected to the positive terminal and a negative terminal connected to the negative terminal at both ends.

[0072] Wherein, the positive electrode connector or the negative electrode connector is respectively connected to the connector;

[0073] When controlling the charge and discharge of a single UPS battery pack, the regulating group controls the charge and discharge of the corresponding UPS battery pack by regulating the on-off of the corresponding connector of the wiring harness.

[0074] By setting the input terminal, the output terminal, the positive electrode connection terminal and the negative electrode connection terminal, the UPS batteries can be connected in parallel, thereby improving the efficiency of UPS battery life detection.

[0075] Specifically, the measurement group includes:

[0076] The temperature sensor is connected to the rectifier to sense the rectifier temperature information.

[0077] Wherein, the temperature sensor is fixed on the rectifier to sense the real-time temperature of the rectifier;

[0078] The transmitter is connected to the temperature sensor and is used to send the real-time rectified temperature information in the temperature sensor to the processing group.

[0079] By setting up a temperature sensor, it is convenient to sense the rectifier temperature information in real time, which reduces the difficulty of monitoring the rectifier temperature and further facilitates users to monitor the performance parameter indicators of the UPS battery.

[0080] Specifically, the treatment groups included:

[0081] A filter element is used to receive real-time rectifier temperature information and perform data filtering on the real-time rectifier temperature information.

[0082] The data filtering is to remove the rectifier temperature information that does not reach or exceeds the normal temperature range in the real-time rectifier temperature information, and generate corresponding filtering data;

[0083] The display is connected to the monitoring group and is used for receiving instructions and displaying them.

[0084] Embodiment 1:

[0085] The temperature sensor senses that the real-time rectification temperature is 9° C. The filter element determines that the real-time rectification temperature is less than the normal temperature range and clears the real-time rectification temperature.

[0086] Embodiment 2:

[0087] The temperature sensor senses that the real-time rectification temperature is 15°C, and the filter element determines that the real-time rectification temperature is within the normal temperature range, and transmits the real-time rectification temperature as filtering data to the monitoring group.

[0101] In a specific implementation, in order to avoid voltage fluctuations in the equipment, the energy storage time that is less than or greater than a threshold value appears again in the filtered data of the UPS battery is used as the remaining battery life for display.
