[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] like Figure 1 As shown, an embodiment of the present application provides a state monitoring method for an emergency power supply system, comprising:

[0052] S101, obtaining a node voltage at a preset position on the emergency power supply system to be tested, and rectifying the node voltage to obtain a DC voltage at a preset position on the emergency power supply system to be tested;

[0053] Exemplarily, the emergency power supply system to be tested is divided into different preset positions, and then the node voltages at different preset positions on the emergency power supply system to be tested are obtained, so that the status of different preset positions on the emergency power supply system to be tested can be simultaneously identified, that is, the daily maintenance efficiency and quality of the emergency power supply system are improved, the time for emergency startup is reduced, and the reliability and timeliness of power supply are improved.

[0054] Exemplarily, node voltages at different preset positions on the emergency power supply system to be tested are obtained, and the node voltages are three-phase voltages. When a subsequent target voltage value is matched with preset data through a microcontroller unit (MCU), the node voltages are rectified to obtain a DC voltage at a preset position on the emergency power supply system to be tested, so that the microcontroller unit (MCU) can operate normally.

[0055] Specifically, the rectification process is implemented using a three-phase rectification chip.

[0056] S102, performing voltage division processing on the DC voltage to obtain a divided voltage, where the divided voltage is less than or equal to a threshold;

[0057] In a possible implementation manner, the step of performing voltage division processing on the DC voltage to obtain the divided voltage includes:

[0058] The DC voltage is divided by resistor voltage division to obtain a divided voltage.

[0059] For example, a large voltage is divided into a small voltage within 250mv by resistor voltage division, and input into the isolation amplifier chip to isolate the high voltage part and the low voltage part to prevent the high voltage from breaking through the microcontroller unit (MCU), and to stably amplify the voltage to achieve a resolution that the microcontroller unit (MCU) can stably identify.

[0060] S103, filtering the divided voltage by a filtering algorithm to obtain a target voltage value;

[0061] Exemplarily, the filtering algorithm refers to an algorithm that uses digital technology to eliminate noise and errors in the signal to make the current measurement more accurate. It is used in the fields of industrial control, power measurement, metrology, etc. The basic principle of the filtering algorithm is to filter out the noise in the actual measurement signal so as to obtain a more accurate value.

[0062] S104: Match the target voltage value with preset data to obtain a matching result, and determine the state of a preset position on the emergency power supply system according to the matching result.

[0063] Exemplarily, the microcontroller unit (MCU) compares the target voltage value with preset data (normal threshold value), records the node voltage state of the current preset position, and then generates a control instruction if the node voltage state of the current preset position is abnormal. The control instruction is used to adjust the circuit state, such as controlling the generator circuit state, controlling the load circuit state, issuing an alarm, etc.

[0064] By acquiring the node voltage at a preset position on the emergency power supply system to be tested, and rectifying the node voltage to obtain the DC voltage at the preset position on the emergency power supply system to be tested; dividing the DC voltage to obtain a divided voltage, which is less than or equal to a threshold; filtering the divided voltage through a filtering algorithm to obtain a target voltage value; matching the target voltage value with preset data to obtain a matching result, and determining the status of the preset position on the emergency power supply system based on the matching result. By collecting and monitoring the status of different positions on the emergency power supply system, the daily maintenance efficiency and quality of the emergency power supply system can be improved, the time consumed for emergency startup can be reduced, and the reliability and timeliness of power supply can be improved.

[0065] In a possible implementation manner, the step of obtaining a node voltage at a preset position on the emergency power supply system to be tested, and rectifying the node voltage to obtain a DC voltage at the preset position on the emergency power supply system to be tested includes:

[0066] Acquiring circuit topology data of the emergency power supply system to be tested;

[0067] Determine the generator circuit, the main circuit, the shunt circuit, the UPS circuit, the first load circuit and the second load circuit on the emergency power supply system to be tested based on the circuit topology data, and use the power supply point of the first load circuit as the first power supply point, and use the power supply point of the second load circuit as the second power supply point, and the preset position includes the generator circuit, the main circuit, the shunt circuit, the UPS circuit, the first power supply point and the second power supply point;

[0068] Obtaining the node voltage of the generator circuit, the node voltage of the main circuit, the node voltage of the branch circuit, the node voltage of the UPS circuit, the node voltage of the first power supply point, and the node voltage of the second power supply point on the emergency power supply system to be tested;

[0069] The node voltage of the generator circuit, the node voltage of the main circuit, the node voltage of the branch circuit, the node voltage of the UPS circuit, the node voltage of the first power supply point and the node voltage of the second power supply point are rectified respectively to obtain a DC voltage at a preset position on the emergency power supply system to be tested.

[0070] Exemplarily, the UPS circuit is an AC uninterruptible power supply circuit, and the connection point between the first load circuit and the main circuit is used as the first power supply point. Similarly, the connection point between the second load circuit and the main circuit is used as the second power supply point.

[0071] Exemplarily, the preset positions on the emergency power supply system to be tested are determined based on the circuit topology data to include: the generator circuit, the main circuit, the branch circuit, the UPS circuit, the first power point and the second power point, that is, by respectively acquiring the node voltage of the generator circuit, the node voltage of the main circuit, the node voltage of the branch circuit, the node voltage of the UPS circuit, the node voltage of the first power point and the node voltage of the second power point, the operating status of different preset positions can be synchronously identified. When the emergency power supply system to be tested fails, the fault location can be found in time, and maintenance can be completed in time.

[0072] In a possible implementation manner, the step of matching the target voltage value with preset data to obtain a matching result includes:

[0073] Acquire source information of the target voltage value, and search the preset data for a preset voltage value corresponding to the source information based on the source information;

[0074] The target voltage value is matched with the preset voltage value to obtain a matching result.

[0075] Exemplarily, the source information of the target voltage value is obtained. When the source information of the target voltage value is a generator circuit, the preset voltage value corresponding to the generator circuit is searched in the preset data, and the target voltage value is matched with the preset voltage value corresponding to the generator circuit to obtain a matching result.

[0076] In a possible implementation, the method further includes:

[0077] The matching result includes sub-results for characterizing the states of different preset positions, the sub-results for characterizing the abnormal state of the preset position are used as the first target result, and the preset position with the abnormal state is used as the first target position;

[0078] A control instruction is generated according to the first target result, and the control instruction is used to control the operating state with respect to the first target position.

[0079] Exemplarily, the matching result includes sub-results for characterizing the status of different preset positions, that is, sub-results for characterizing the status of the generator circuit, sub-results for characterizing the status of the main circuit, sub-results for characterizing the status of the branch circuit, sub-results for characterizing the status of the UPS circuit, sub-results for characterizing the status of the first power point, and sub-results for characterizing the status of the second power point.

[0080] Exemplarily, the preset position of the abnormal state determined based on the voltage is recorded, and then control instructions are generated in a targeted manner to achieve efficient maintenance and fault avoidance for the emergency power supply system to be tested.

[0081] In a possible implementation, the method further includes:

[0082] The matching result includes sub-results for characterizing the states of different preset positions, the sub-results for characterizing that the state of the preset position is normal are used as the second target result, and the preset position with a normal state is used as the second target position;

[0083] Acquiring temperature data of the second target position, and determining a temperature state of the second target position according to the temperature data;

[0084] If the temperature state of the second target position is an abnormal state, alarm information for the second target position is generated according to the temperature data.

[0085] For example, since the emergency power supply system to be tested will generate heat during operation, which may easily cause accidents, it is not completely reliable to rely solely on voltage to judge the status of different preset positions. Testing the second target position through temperature data can improve the safety of the emergency power supply system to be tested.

[0086] In a possible implementation, the method further includes:

[0087] Compressing the target voltage value and the matching result corresponding to the target voltage value according to a preset protocol format to obtain a data packet to be sent;

[0088] The data packet to be sent is sent to a preset display device in an encrypted transmission manner.

[0089] For example, data compression can reduce the amount of data transmission and improve parameter efficiency, while encrypted transmission can ensure data security and avoid data leakage.

[0090] Specifically, the data is packaged in 104 protocol format and sent to the cluster gateway through the microcontroller unit (MCU) serial port and MAX485 chip using 485 protocol. The 104 protocol data packet is transmitted to the gateway device through 485. The gateway device encrypts the data according to the certificate issued by the server and transmits the data to the server through the IoT card. The server receives the data packet and decrypts it according to the certificate.

[0093] The output voltage is connected to the DC24V to DC5V module: the output 24V DC voltage is connected to the input pin 5 of the DC24V to DC5V module XL4015E1 chip, and is converted into a 5V DC voltage through the chip and output from pin 3.

[0094] 5V voltage management, power supply for the main control chip is TPRT9013-33GB chip through 5V to 3V3, input on pin 1 and output on pin 5.

It is internally connected to the 2, 3, and 4 pins of the U7 SGBJ2510 chip, and rectified into a DC voltage and output through the 1 and 5 pins. The output voltage enters the 2 and 3 pins of the chip AMC1200BDWVR through a resistor divider, is isolated and amplified, and then output to the ADC pin of the microcontroller through the 7 pin.

[0096] Isolation voltage circuit: Provide 5V and 3.3V isolation voltages for the AMC1200BDWVR chip respectively, both of which are input through pin 2 and output through pin 4.
