Description

Technical Field

[0001] This application belongs to the field of battery monitoring and self-testing, specifically relating to a self-testing system for a UPS battery monitoring module. Background Technology

[0002] UPS (Uninterruptible Power Supply) is a type of uninterruptible power supply containing an energy storage device. When the mains power input is normal, the UPS stabilizes the mains power and supplies it to the load, while simultaneously charging its internal battery. When the mains power is interrupted, the UPS continues to supply AC power to the load, enabling the load to maintain normal operation. To ensure the stable operation of the UPS, the UPS battery is monitored through a UPS battery monitoring module. However, existing UPS battery monitoring modules can only perform simple monitoring of the UPS battery. When the battery monitoring module itself malfunctions, it provides a fault indication but cannot further indicate the type of fault, thus affecting the speed of UPS battery maintenance. Summary of the Invention

[0003] To address the issue that existing UPS monitoring modules cannot further indicate the type of battery module fault, a self-testing system for UPS battery monitoring modules is proposed.

[0004] A self-testing system for a UPS battery monitoring module includes: a housing, a control unit, a storage unit, a data acquisition unit, a transmission interface, and a fault warning unit; the control unit and the storage unit are disposed inside the housing, the fault warning unit is disposed on the outer surface of the housing, and the transmission interface is disposed on the outer surface of the housing.

[0005] The fault warning unit includes a first warning light, a second warning light, a third warning light, a fourth warning light, and a speaker;

[0006] The control unit generates a self-test signal at fixed intervals, and the self-test signal transmitter of the control unit is communicatively connected to the self-test signal receiver of the acquisition unit.

[0007] After receiving the self-test signal, the acquisition unit obtains the UPS battery parameters. The UPS battery parameter transmitting end of the acquisition unit is simultaneously connected to the UPS battery parameter receiving end of the control unit and the UPS battery parameter receiving end of the storage unit. The UPS battery parameter output end of the storage unit is connected to one end of the transmission interface, and the other end of the transmission interface is connected to the external device.

[0008] UPS battery parameters include UPS battery voltage signal, UPS battery current signal, UPS battery temperature signal, and UPS battery internal resistance signal;

[0009] The control unit is also used to determine whether the voltage, current, temperature, and internal resistance values ​​corresponding to the received UPS battery parameters belong to the set voltage, current, temperature, and internal resistance ranges, respectively. If the voltage value does not belong to the voltage range, a voltage fault signal is generated, and the first warning light is activated and the speaker broadcasts a first warning voice message based on the voltage fault signal. If the current value does not belong to the current range, a current fault signal is generated, and the second warning light is activated and the speaker broadcasts a second warning voice message based on the current fault signal. If the temperature value does not belong to the temperature range, a temperature fault signal is generated, and the third warning light is activated and the speaker broadcasts a third warning voice message based on the temperature fault signal. If the internal resistance value does not belong to the internal resistance range, an internal resistance fault signal is generated, and the fourth warning light is activated and the speaker broadcasts a fourth warning voice message based on the internal resistance fault signal.

[0010] The beneficial effects of this invention are as follows: The self-testing system for a UPS battery monitoring module proposed in this invention collects UPS battery voltage, current, temperature, and internal resistance signals through a data acquisition unit. Based on all the collected signals, it determines the specific type of fault and issues corresponding warnings when a fault occurs. This system achieves comprehensive data acquisition, monitoring, and self-testing of the UPS battery monitoring module's parameters, differentiates and issues warnings for these parameters, facilitates subsequent maintenance of the UPS battery monitoring module, and ensures stable operation of the UPS battery.

[0013] Detailed implementation: The following will refer to the appendices in the embodiments of the present invention. Figure 1 To be continued Figure 2 This description explains the embodiments of the present invention, providing a clear and complete description of the technical solutions in these embodiments:

[0014] A self-testing system for a UPS battery monitoring module includes: a housing 1, a control unit, a storage unit, a data acquisition unit, a transmission interface, and a fault warning unit; the control unit and the storage unit are disposed inside the housing 1, the fault warning unit is disposed on the outer surface of the housing, and the transmission interface is disposed on the outer surface of the housing.

[0015] The fault warning unit includes a first warning light 2, a second warning light 3, a third warning light 4, a fourth warning light 5, and a speaker 6;

[0016] The control unit generates a self-test signal at fixed intervals, and the self-test signal transmitter of the control unit is communicatively connected to the self-test signal receiver of the acquisition unit.

[0017] After receiving the self-test signal, the acquisition unit obtains the UPS battery parameters. The UPS battery parameter transmitting end of the acquisition unit is simultaneously connected to the UPS battery parameter receiving end of the control unit and the UPS battery parameter receiving end of the storage unit. The UPS battery parameter output end of the storage unit is connected to one end of the transmission interface 7, and the other end of the transmission interface 7 is connected to an external device.

[0018] UPS battery parameters include UPS battery voltage signal, UPS battery current signal, UPS battery temperature signal, and UPS battery internal resistance signal;

[0019] The control unit is also used to determine whether the voltage, current, temperature, and internal resistance values ​​corresponding to the received UPS battery parameters belong to the set voltage, current, temperature, and internal resistance ranges, respectively. If the voltage value does not belong to the voltage range, a voltage fault signal is generated, and the first warning light 2 is activated and the speaker 6 broadcasts a first warning voice message based on the voltage fault signal. If the current value does not belong to the current range, a current fault signal is generated, and the second warning light 3 is activated and the speaker 6 broadcasts a second warning voice message based on the current fault signal. If the temperature value does not belong to the temperature range, a temperature fault signal is generated, and the third warning light 4 is activated and the speaker 6 broadcasts a third warning voice message based on the temperature fault signal. If the internal resistance value does not belong to the internal resistance range, an internal resistance fault signal is generated, and the fourth warning light 5 is activated and the speaker 6 broadcasts a fourth warning voice message based on the internal resistance fault signal.

[0020] Specifically, UPS battery voltage signal, UPS battery current signal, UPS battery temperature signal, and UPS battery internal resistance signal are important parameters for UPS battery operation monitoring. The self-test system of the UPS battery monitoring module acquires UPS battery parameters through the acquisition unit and judges the corresponding voltage, current, temperature, and internal resistance values ​​of the acquired UPS battery parameters. When any of these values ​​is abnormal, corresponding warning lights and warning voice broadcasts are activated, providing further prompts for UPS battery monitoring module faults, facilitating later UPS battery maintenance, and ensuring stable UPS battery operation.

[0021] Furthermore, the control unit is a microcontroller of model STM32F103C8T6.

[0022] Specifically, the STM32F103C8T6 microcontroller features fast processing and response speeds, enabling it to quickly determine whether the received UPS battery parameters (voltage, current, temperature, and internal resistance) fall within the set voltage, current, temperature, and internal resistance ranges, thereby enhancing the timeliness of the UPS battery monitoring module's self-test system.

[0023] Furthermore, the data acquisition unit includes a voltage sensor, a current sensor, a temperature sensor, and an internal resistance tester;

[0024] The voltage sensor (UPS battery voltage signal transmitter) is communicatively connected to the control unit (UPS battery voltage signal receiver); the current sensor (UPS battery current signal transmitter) is communicatively connected to the control unit (UPS battery current signal receiver); the temperature sensor (UPS battery temperature signal transmitter) is communicatively connected to the control unit (UPS battery temperature signal receiver); and the internal resistance tester (UPS battery internal resistance signal transmitter) is simultaneously communicatively connected to the control unit (UPS battery internal resistance signal receiver).

[0025] Furthermore, it also includes a human-machine interface unit (HMI), whose self-test signal transmitter is communicatively connected to the self-test signal receiver of the data acquisition unit; and whose UPS battery parameter receiver is communicatively connected to the UPS battery parameter transmitter of the data acquisition unit. Specifically, based on actual UPS battery testing needs, the HMI generates and sends self-test signals to facilitate timely testing of the UPS battery.

[0026] Furthermore, the fixed time ranges from 0 to 5 minutes.

[0027] Furthermore, the first warning light 2, the second warning light 3, the third warning light 4, and the fourth warning light 5 are all LED lights of different colors.

[0028] Specifically, different colored LEDs facilitate the differentiation of fault types, enabling relevant personnel to promptly address UPS battery issues and improve UPS battery maintenance efficiency.

[0029] Furthermore, the voltage fault signal, current fault signal, temperature fault signal, and internal resistance fault signal are all digital signals.

[0030] Furthermore, the transmission interface is an RS485 transmission interface.
