[0017] Figure 1 : is a flow chart of a monitoring method for an underground station building based on digital twin according to an embodiment of the present invention. In the present invention, the monitoring process may include: In step S1, a digital twin model of the underground station building is obtained and established.

[0018] In step S2, a data acquisition device is configured in the equipment and environment of a real underground station.

[0019] In step S3, according to the position of the data acquisition device in the real underground station building, a corresponding virtual acquisition device is set at the corresponding position in the digital twin model.

[0020] In step S4, the data acquisition device collects data from the equipment in the actual underground station building in real time, and displays the same data on the virtual equipment in the digital twin model.

[0021] In step S5, the equipment and environment in the underground station house are analyzed according to the data information displayed on the virtual device, an alarm is issued in time when a fault is found, and the corresponding fault location is displayed in the digital twin model.

[0022] In the present invention, when monitoring an underground station house, a digital twin model of the underground station house can be obtained, and then a data acquisition device can be configured in the equipment and environment of the real underground station house. According to the position of the data acquisition device in the real underground station house, a corresponding virtual acquisition device can be set at the corresponding position device in the digital twin model. After the virtual device is set, the same data can be displayed on the virtual device in the digital twin model according to the data of the equipment in the real underground station house collected in real time by the data acquisition device. According to the data information displayed on the virtual device, the equipment and environment in the underground station house can be analyzed, and an alarm can be issued in time when a fault is found, and the corresponding fault location can be displayed in the digital twin model. This monitoring method can monitor the underground station house in real time and issue an alarm in time when a fault occurs.

[0023] In one embodiment of the present invention, Figure 2 As shown, the process of collecting data may include: In step S6, vibration sensors are installed on various devices in the actual underground station building to collect vibration data of the devices.

[0024] In step S7, a water sensor is installed in the cable trench of the actual underground station building to measure whether water has entered the cable trench of the underground station building.

[0025] In step S8, temperature and humidity sensors are installed around the actual underground station building to monitor the temperature and humidity indicators inside the underground station building.

[0026] In step S9, the operation data of each device in the underground station building is directly collected.

[0027] In the present invention, when collecting data, vibration sensors can be installed on each device of the real underground station house, so that the vibration data of the corresponding equipment can be collected. Because the vibration of the equipment during normal operation is different from the vibration when there is a fault, it is possible to judge whether the equipment has a fault through the collected vibration data. A water immersion sensor can be installed in the cable trench of the real underground station house, so that it can be measured whether water has entered the cable trench of the underground station house. Temperature and humidity sensors can be set around the real underground station house, so that the temperature and humidity indicators in the underground station house can be monitored. When the temperature or humidity indicators exceed the threshold, an alarm can be issued to remind the staff to pay attention. The operation data of each device in the underground station house can also be directly collected, and the operation data of each device can intuitively reflect whether it has a fault.

[0028] In one embodiment of the present invention, Figure 3 As shown, the process of generating a virtual acquisition device may include: In step S10, the coordinate position in the digital twin model is set according to the coordinate position of the actual underground station building.

[0029] In step S11, the actual coordinate position of the data acquisition device in the actual underground station building is obtained.

[0030] In step S12, the actual coordinate position of the data acquisition device in the real underground station building is converted into the digital twin model to obtain the coordinate information of the data acquisition device in the digital twin model.

[0031] In step S13, a corresponding virtual data acquisition device is generated on the virtual device according to the coordinate information of the data acquisition device in the digital twin model.

[0032] In the present invention, when generating the corresponding virtual acquisition device, the coordinate position in the digital twin model can be set according to the coordinate position of the real underground station house, and then the actual coordinate position of the data acquisition device in the real underground station house can be obtained. After obtaining the actual coordinate position, the actual coordinate position of the data acquisition device in the real underground station house can be converted into the digital twin model, so that the coordinate information of the data acquisition device in the digital twin model can be obtained. According to the coordinate information of the data acquisition device in the digital twin model, the corresponding virtual acquisition device can be generated on the virtual device, and then the corresponding acquisition information can be generated near the virtual acquisition device for easy viewing by the staff.

[0033] In one embodiment of the present invention, Figure 4 As shown, the process of displaying the collected data may include: In step S14, data of equipment in a real underground station building is collected in real time, and each data is marked with a time tag.

[0034] In step S15, a curve chart about time fluctuation is constructed based on the time tags and the collected device data.

[0035] In step S16, the curve graph is synchronized to the corresponding virtual device, and the latest data collected in real time is displayed.

[0036] In the present invention, when collecting data of equipment in an underground station, the data of the equipment in the real underground station collected in real time can be marked with a time tag. After the time tag is marked, a curve chart about time fluctuation can be constructed according to the time tag and the collected equipment data. After the curve chart is obtained, the curve chart can be synchronized to the corresponding virtual device, and the latest data collected in real time can be displayed, so that it is convenient for staff to observe the operation trend of the equipment.

[0037] In one embodiment of the present invention, Figure 5 As shown, the first process of fault monitoring may include: In step S17, data information displayed on the virtual device is obtained.

[0038] In step S18, water immersion information, temperature and humidity information, and equipment operation information in the data information are obtained.

[0039] In step S19, it is determined whether the data in the water immersion information, the temperature and humidity information, and the equipment operation information exceeds the threshold.

[0040] In step S20, when the threshold is exceeded, an alarm is issued according to the corresponding type and displayed at the corresponding position.

[0041] In the present invention, when fault monitoring is performed, data information displayed on the virtual device can be obtained. The data information may include vibration information, water immersion information, temperature and humidity information, and device operation information. After obtaining the water immersion information, temperature and humidity information, and device operation information, it can be determined whether the data in the water immersion information, temperature and humidity information, and device operation information exceeds a threshold. In the case of exceeding the threshold, an alarm can be issued according to the corresponding type, and it can be displayed at the corresponding position.

[0043] In step S22, real-time vibration data in the data information is obtained.

[0044] In step S23, the vibration data is pre-processed.

[0045] In step S24, the preprocessed vibration data is subjected to Fourier transform to obtain a corresponding frequency domain signal.

[0046] In step S25, the corresponding working condition is matched according to the corresponding frequency domain signal, and in the event of a faulty working condition, an alarm is issued and displayed at the corresponding position.

[0047] In the present invention, when performing fault monitoring, historical vibration data in the data information can be obtained, and the historical vibration data can be Fourier transformed, so that the working conditions corresponding to each frequency domain signal can be obtained, and then the real-time vibration data in the data information can be obtained. After obtaining the vibration data, the vibration data can be preprocessed so that the vibration data meets the requirements. After preprocessing, the vibration data can be Fourier transformed, so that the corresponding frequency domain signal can be obtained. After obtaining the frequency domain signal, the corresponding working condition can be matched according to the corresponding frequency domain signal. In the case of a faulty working condition, an alarm can be issued, and it can be displayed at the corresponding position.

[0048] In one embodiment of the present invention, Figure 7 As shown, the process of frequency domain transformation may include: In step S26, real-time vibration data is acquired.

[0049] In step S27, the vibration data is converted into a frequency domain signal according to formula (1): , formula (1) in, represents the frequency domain signal, Represents vibration data, Indicates frequency, represents the imaginary unit, Indicates the frequency The sine wave.

[0050] In the present invention, when performing frequency domain conversion, real-time vibration data can be obtained first, and the vibration data can be data that changes over time. After obtaining the vibration data, it can be converted into a frequency domain signal according to formula (1), and the current operating state of the equipment can be determined according to the working condition corresponding to the frequency domain signal.

According to the position of the data acquisition device in the real underground station building, a corresponding virtual acquisition device can be set at the corresponding position device in the digital twin model. After the virtual device is set, the same data can be displayed on the virtual device in the digital twin model according to the data of the equipment in the real underground station building collected in real time by the data acquisition device. According to the data information displayed on the virtual device, the equipment and environment in the underground station building can be analyzed, and an alarm can be issued in time when a fault is found, and the corresponding fault location can be displayed in the digital twin model.
