Description

Technical Field

[0001] This invention relates to the field of UPS power supply technology, and in particular to a UPS power supply based on an ARM processor dual temperature compensation algorithm. Background Technology

[0002] UPS (Uninterruptible Power Supply) is a device that provides stable power to electronic equipment. UPS power supplies are mainly used to provide temporary power when the power grid supply is unstable or there is a power outage, protecting equipment from damage caused by power fluctuations, voltage fluctuations, or even power outages. UPS power supplies use built-in batteries or supercapacitors to immediately switch to backup power when the power grid fails, ensuring continuous power supply to the equipment and preventing data loss or equipment damage.

[0003] Existing UPS power supplies have poor adaptability to changes in ambient temperature during use. When the ambient temperature fluctuates greatly, the stability and power supply efficiency of the UPS power supply will be affected, thereby affecting the stable power supply to electronic equipment. To address this, this application proposes a UPS power supply based on a dual temperature compensation algorithm of an ARM processor. Summary of the Invention

[0004] Based on the technical problems existing in the background technology, this invention proposes a UPS power supply based on a dual temperature compensation algorithm of ARM processor.

[0005] The UPS power supply based on the dual temperature compensation algorithm of ARM processor proposed in this invention includes a UPS power supply body connected to a remote monitoring terminal and electronic equipment. The UPS power supply body includes an ARM processor, a dual temperature sensor module, a battery pack module, a communication interface module, an input power module, an alarm module, an output power module, a power filtering module, an overload protection module, and a DC / AC conversion module.

[0006] The ARM processor is connected to the dual temperature sensor module, battery pack module, communication interface module, input power module, alarm module, output power module, power filter module, and overload protection module. The communication interface module is connected to the remote monitoring terminal. The input power module is connected to the electronic equipment. The battery pack module is connected to the dual temperature sensor module and DC / AC conversion module. The output power module is connected to the DC / AC conversion module, overload protection module, electronic filter module, and electronic equipment.

[0007] Preferably, the dual temperature sensor module is used to monitor the temperature of the battery pack module in real time and transmit the temperature data to the ARM processor. The specific logical steps are as follows:

[0008] S101: The temperature sensor in the dual temperature sensor module monitors the temperature of the battery pack module in real time. The temperature sensor generates an electrical signal by receiving temperature changes, and the electrical signal changes according to the temperature changes.

[0009] S102: The detected temperature signal is converted into a digital signal by the analog-to-digital converter (ADC) of the dual temperature sensor module. The digital signal is transmitted to the microcontroller of the dual temperature sensor module via the communication bus. When the temperature signal is converted into a digital signal, it is used... The formula is transformed, where n represents the resolution bit depth of the ADC;

[0010] S103: The microcontroller of the dual temperature sensor module packages the collected temperature data into a data packet and transmits it through the interface with the ARM processor module.

[0011] Preferably, the ARM processor serves as the control core, monitoring the status and data of each module in real time. The ARM processor is used to implement a temperature compensation algorithm, adjusting parameters based on temperature data to compensate for the impact of the battery pack module's temperature on battery performance and operation. The adjusted parameters are the battery charging and discharging parameters.

[0012] The execution logic steps of the temperature compensation algorithm are as follows:

[0013] S201: The ARM processor processes and parses the received temperature data. This processing and parsing includes data correction and filtering. The accuracy of the data is improved through processing and parsing, and the processed temperature data is stored in variables for subsequent temperature compensation algorithm calculations and adjustments.

[0014] When correcting the data, a zero-point correction method is required. The formula used for this correction is: T correcte =T measured -T offset ;

[0015] Where T measured It is the sensor's raw measurement value, T offset It is a known offset value, which is determined through calibration;

[0016] The filtering process uses a moving average filter, which calculates the average value of the data within a sliding window to smooth short-term fluctuations and remove noise from the temperature data. The formula used in the calculation is as follows:

[0017]

[0018] Where N is the window size, and T[n] is the temperature value of the nth sample;

[0019] S202: Based on the set temperature compensation algorithm, the ARM processor performs real-time analysis and calculation of the temperature data of the battery pack module;

[0020] S203: Based on the results obtained from the algorithm, the ARM processor adjusts the battery charging and discharging parameters of the battery pack module to optimize battery performance;

[0021] S204: The ARM processor controls the operation of the entire UPS power supply based on the results of the temperature compensation algorithm.

[0022] Preferably, the specific logical steps of S202 are as follows:

[0023] S2021: First, define the temperature threshold, including the upper limit threshold T_high and the lower limit threshold T_low, and determine whether the battery is within the normal operating range based on the temperature threshold;

[0024] S2022: Calculate the temperature difference based on the reference temperature and the acquired temperature data. The temperature difference formula is: ΔT=T_current-T_ref, where T_current represents the acquired actual temperature data and T_ref represents the set reference temperature.

[0025] S2023: Calculate the compensation coefficient K based on the temperature difference in S2022, and determine the impact on battery performance based on the compensation coefficient K. Factors affecting battery performance include battery capacity, resistance and charging efficiency. Increased temperature usually leads to a decrease in the usable capacity of the battery. Temperature changes affect the fluidity of the electrolyte inside the battery, thereby affecting the internal resistance of the battery. Increased temperature will reduce the charging efficiency of the battery.

[0026] The formula for its calculation is: k = 1 + α * ΔT, where α is the temperature compensation coefficient, representing the sensitivity of the parameter to temperature.

[0027] S2024: Calculate the battery charging and discharging parameters based on the compensation coefficient K. The calculation formula is as follows:

[0028] Calculation of charging and discharging voltage parameters: V charge =V nominal ×k, where V charge This is the adjusted voltage, V nominal This refers to the battery's rated voltage. For example, if the ambient temperature is low, the compensation factor K may be less than 1, thus requiring a reduction in the charging voltage to avoid overcharging and damage.

[0029] Calculation of charging and discharging current parameters: I charge =I nominal ×k, where I charge It is the adjusted current, I nominalThis is the battery's rated current. For example, at high temperatures, the compensation coefficient K may be less than 1 to reduce the charging and discharging current and prevent the battery from overheating; at low temperatures, the charging and discharging current may also be reduced to avoid damage caused by low internal reaction efficiency.

[0030] Preferably, the input power module is used to monitor the voltage parameters of the electronic device. When the electronic device is unstable or loses power, the ARM processor switches to the output power module to supply power to the electronic device. During power supply, the battery module converts the power supply through the DC / AC conversion module and transmits it to the output power module, which then supplies power to the electronic device.

[0031] Preferably, the power filtering module is used to filter the power output from the output power module, eliminating noise and interference in the power supply and ensuring the purity and stability of the output power. The specific logical steps are as follows:

[0032] S301: The power filtering module first collects the power signal output by the power supply module;

[0033] S302: The power filtering module selects a low-pass filter to filter the acquired signal, removing unwanted frequency components and retaining the required power signal. During the filtering process, it uses... The formula is used for calculation;

[0034] Where w c H(s) is the cutoff frequency of the filter, H(s) represents the frequency response to frequency (S), s = jω represents the complex frequency, j is the imaginary unit, and ω is the angular frequency.

[0035] Because there is a lot of high-frequency noise in the UPS power supply itself, including electromagnetic interference (EMI) and radio frequency interference (RFI) generated by the power supply and equipment switching, a low-pass filter is selected to remove high-frequency noise.

[0036] S303: Perform frequency analysis on the filtered signal in S302 to ensure that interference signals within the expected range have been filtered out;

[0037] S304: The processed, clean, and stable power signal will be sent out to provide electronic equipment with stable and reliable operation.

[0038] Preferably, the overload protection module is used to monitor the output current and prevent the UPS power supply body from overloading, thereby protecting the connected electronic equipment from damage. Its specific logic steps are as follows:

[0039] S401: The current value output by the power supply module is measured by a current sensor, and a current threshold is set in the overload protection module. When the current exceeds the value, an overload is considered to have occurred. The threshold setting should take into account the maximum current load that the UPS power supply can withstand and the rated load of the connected electronic equipment.

[0040] S402: The overload protection module compares the real-time measured current value with the set threshold, sets the real-time measured current value as X, and sets the set threshold as Y. If X>Y, it means that the current value exceeds the set threshold and is identified as an overload state. If X≤Y, it means that the current is normal and there is no overload.

[0041] S403: When an overload is detected in S402, a signal is transmitted to the ARM processor. The ARM processor controls the output power module to disconnect, cut off the output power, and stop supplying power to the electronic device.

[0042] S404: The ARM processor controls the alarm module to emit sound or light signals to alert the user of overload conditions. At the same time, the ARM processor transmits the signal to the remote monitoring terminal through the communication interface module, and the remote monitoring terminal notifies the personnel at the remote monitoring terminal by sending an SMS.

[0043] Preferably, the communication interface module is used to realize communication between the remote monitoring terminal and the ARM processor. The data received by the ARM processor is transmitted to the remote monitoring terminal through the communication interface module, thereby realizing the function of remote monitoring.

[0044] Compared with existing technologies, the beneficial effects of this invention are:

[0045] This invention monitors the internal temperature changes of the UPS power supply and uses an ARM processor and a dual temperature compensation algorithm to perform temperature compensation based on these changes. This optimizes the performance of the UPS power supply, improves its stability and efficiency, and ensures stable operation under different temperature conditions. Furthermore, the inclusion of a power filtering module and an overload protection module further enhances the stability of the UPS power supply, ensuring reliable power supply to electronic devices under various circumstances.

The communication interface module is connected to the remote monitoring terminal. The input power module is connected to the electronic equipment. The battery pack module is connected to the dual temperature sensor module and DC / AC conversion module. The output power module is connected to the DC / AC conversion module, overload protection module, electronic filter module, and electronic equipment. The input power module is used to monitor the voltage parameters of the electronic equipment. When the electronic equipment is unstable or loses power, the ARM processor switches to the output power module to supply power to the electronic equipment. During power supply, the battery pack module converts the power supply through the DC / AC conversion module and transmits it to the output power module, which then supplies power to the electronic equipment.

[0052] The communication interface module is used to realize communication between the remote monitoring terminal and the ARM processor. The data received by the ARM processor is transmitted to the remote monitoring terminal through the communication interface module, thereby realizing the remote monitoring function.

The formula is converted, where n represents the resolution bits of the ADC. For example, a dual temperature sensor module is connected to a microcontroller with a 10-bit ADC resolution. The reference voltage is set to 5V. The output voltage of sensor A in the dual temperature sensor module is proportional to the ambient temperature, while the output voltage of sensor B is proportional to the temperature of the object being measured. The output voltages of sensor A and sensor B are 1.5V and 2.5V respectively. The voltage difference between the two sensors is calculated to detect the change or difference between the ambient temperature and the object temperature: Vdifference = VB. - VA = 2.5V - 1.5V = 1.0V, using the voltage difference V_difference = 1.0V as the input signal for the ADC. 204.8 is the digital signal used to detect temperature;

[0056] S103: The microcontroller of the dual temperature sensor module packages the collected temperature data into a data packet and transmits it through the interface with the ARM processor module.

The accuracy of the data is improved through processing and parsing, and the processed temperature data is stored in variables for subsequent temperature compensation algorithm calculations and adjustments.

[0060] Because the dual temperature sensors have a fixed offset value that needs to be removed through calibration, zero-point calibration is required when calibrating the data. The formula used for calibration is: T correcte =T measured -T offset T measured It is the sensor's raw measurement value, T offset It is a known offset value, which is determined through calibration;

[0061] Meanwhile, ambient temperature affects the accuracy of the dual temperature sensors, requiring a compensation term for correction.

S403: When an overload is detected in S402, a signal is transmitted to the ARM processor, and the ARM processor controls the output power module to be disconnected, cuts off the output power, and stops supplying power to the electronic device; S404: The ARM processor controls the alarm module to emit a sound or light signal alarm to remind the user of the overload condition. At the same time, the ARM processor transmits the signal to the remote monitoring end through the communication interface module, and the remote monitoring end reminds the remote monitoring end personnel by sending a text message.

8. The UPS power supply based on the ARM processor dual temperature compensation algorithm according to claim 1, characterized in that: The communication interface module is used to realize the communication between the remote monitoring terminal and the ARM processor. The data received by the ARM processor is transmitted to the remote monitoring terminal through the communication interface module, thereby realizing the remote monitoring function.
