[0056] Based on the problems existing in the prior art, the embodiment of the present disclosure provides a power-off protection control method for a CT scanning device, which is applied to a CT scanning system. The CT scanning system at least includes a CT scanning device, a main power supply of the CT scanning device, a first switch module, and a backup power supply.

[0057] In a specific embodiment, the first switch module is a single-pole double-throw switch. In the default state, the moving contact of the first switch module is electrically connected to the first static contact. At this time, the main power supply of the CT scanning device is electrically connected to the power grid power supply device through the first switch module.

At this time, the main power supply of the CT scanning device is electrically connected to the backup power supply through the first switch module, and the main power supply of the CT scanning device is used to power each module of the CT scanning device.

[0058] S110, determining power outage probability data of power supply equipment of the power grid according to power consumption equipment data, power supply equipment data of the power grid, meteorological data and a historical power outage protection data group.

[0059] The historical power outage protection data group includes multiple historical power outage protection data, and any historical power outage protection data includes historical power consumption equipment data, historical power grid power supply equipment data and historical meteorological data.

[0060] Specifically, the power equipment data include transformer load, transformer temperature, line aging degree, load change rate, etc.; the power grid power supply equipment data include grid voltage, grid current, frequency and harmonics, etc.; the meteorological data include wind speed, temperature, humidity and meteorological information, etc.

[0061] As a specific implementable method, power outage probability data of power grid power supply equipment is determined based on power-consuming equipment data, power grid power supply equipment data, meteorological data and a historical power outage protection data group, including: training a power outage prediction model for power grid power supply equipment based on the historical power outage protection data group to obtain a target power outage prediction model for power grid power supply equipment; inputting power-consuming equipment data, power grid power supply equipment data and meteorological data into the target power outage prediction model for power grid power supply equipment to determine the power outage probability data for power grid power supply equipment.

[0062] Specifically, the historical power outage protection data group is first divided into a training set and a test set, wherein the data of the training set accounts for 70% of the number of historical power outage protection data included in the historical power outage protection data group, and the data of the test set accounts for 30% of the number of historical power outage protection data included in the historical power outage protection data group. The power outage prediction model for power grid power supply equipment is trained through the training set, and then the power outage prediction model for power grid power supply equipment is verified through the test set to see whether it converges. When the power outage prediction model for power grid power supply equipment converges, the corresponding model is the target power outage prediction model for power grid power supply equipment. Then, the collected power consumption equipment data, power grid power supply equipment data, and meteorological data are input into the target power outage prediction model for power grid power supply equipment to determine the power outage probability data of power grid equipment in the future period.

[0063] As another specific implementable method, power outage probability data of power grid power supply equipment is determined based on power-consuming equipment data, power grid power supply equipment data, meteorological data and a historical power outage protection data group, including: training a power outage prediction model for power grid power supply equipment based on the historical power outage protection data group to obtain a target power grid power supply equipment power outage prediction model; inputting the power-consuming equipment data into the target power grid power supply equipment power outage prediction model to determine first sub-power outage probability data of the power grid power supply equipment; inputting the power grid power supply equipment data into the target power grid power supply equipment power outage prediction model to determine second sub-power outage probability data of the power grid power supply equipment; inputting meteorological data into the target power grid power supply equipment power outage prediction model to determine third sub-power outage probability data of the power grid power supply equipment; and determining the power outage probability data of the power grid power supply equipment based on the first sub-power outage probability data, the second sub-power outage probability data and the third sub-power outage probability data and the weight coefficients corresponding to each sub-power outage probability data.

[0064] Specifically, firstly, the historical power outage protection data group is divided into a training set and a test set, wherein the data of the training set accounts for 70% of the number of historical power outage protection data included in the historical power outage protection data group, and the data of the test set accounts for 30% of the number of historical power outage protection data included in the historical power outage protection data group. The power outage prediction model of the power grid power supply equipment is trained through the training set, and then the power outage prediction model of the power grid power supply equipment is verified through the test set to see whether it converges. When the power grid power supply equipment power outage prediction model converges, the corresponding model is the target power grid power supply equipment power outage prediction model. Then, the collected power consumption equipment data, power grid power supply equipment data and meteorological data are respectively input into the target power grid power supply equipment power outage prediction model to determine the sub-power outage probability data of the power grid equipment in the future period. Finally, the power outage probability data of the power grid power supply equipment is determined according to each sub-power outage probability data and the weight coefficient of each sub-power outage probability data.

[0065] S120: Acquire real-time status data of power supply equipment of the power grid.

[0066] A specific implementation method is to collect real-time status data of the power supply equipment of the power grid through a signal acquisition module on the line network between the power supply equipment of the power grid and the main power supply of the CT scanning equipment.

[0067] The real-time status data of the power supply equipment of the power grid includes online status data and offline status data (offline status includes power failure or short circuit, etc.).

[0068] S130. When the real-time status data is in an offline state, and / or the power-off probability data is greater than or equal to a preset threshold, a first control signal is generated to the first switch module to electrically connect the main power supply of the CT scanning device to the backup power supply through the first switch module, and a second control signal is generated to the scanning module, the tube and the data storage module of the CT scanning device to control the scanning module, the tube and the data storage module to perform a target response action.

[0069] In a specific implementation, step S110 is used to obtain power outage probability data of the power grid power supply equipment that may experience a power outage in a future time period based on the collected power-consuming equipment data, power grid power supply equipment data and meteorological data. In step S120, real-time status data of the power grid power supply equipment is obtained. When the power outage probability data of the power grid power supply equipment that may experience a power outage in a future time period is greater than a preset threshold, and / or the real-time status data of the power grid power supply equipment is in an offline state, a first control signal is generated to the first switch module, so that the main power supply of the CT scanning device is electrically connected to the backup power supply through the first switch module, so as to avoid the CT scanning device being unable to complete the current CT scanning work due to power outage of the power grid power supply equipment or at an unknown time.

[0070] In addition, by generating a second control signal to the scanning module, the tube and the data storage module of the CT scanning device, the scanning module, the tube and the data storage module are controlled to perform a target response action. Among them, the target response action of the scanning module is to move to the initial position and the rotation angle is 0 degrees, the target response action of the tube is to close the tube, and the response action of the data storage module is to perform a data storage operation. By generating a second control signal to the scanning module, the tube and the data storage module of the CT scanning device, the scanning module, the tube and the data storage module are controlled to perform a target response action, so as to avoid the occurrence of problems such as damage to the CT scanning equipment, data loss and the inability of patients to leave safely due to accidental power failure of the power supply equipment of the power grid.

[0071] The power failure protection control method for CT scanning equipment provided by the embodiment of the present disclosure first determines the power failure probability data of the power supply equipment according to the power consumption equipment data, the power supply equipment data of the power grid, the meteorological data and the historical power failure protection data group; then obtains the real-time status data of the power supply equipment; finally, when the real-time status data is offline, and / or the power failure probability data is greater than or equal to the preset threshold, generates a first control signal to the first switch module, so that the main power supply of the CT scanning equipment is electrically connected to the backup power supply through the first switch module, and generates a second control signal to the scanning module, the tube and the data storage module of the CT scanning equipment to control the scanning module, the tube and the data storage module to perform the target response action. On the one hand, by outputting the first control signal, the main power supply of the CT scanning equipment is electrically connected to the backup power supply through the first switch module, so as to avoid the CT scanning equipment being unable to complete the current CT scanning work due to the power failure of the power supply equipment or the power failure of the power supply equipment at an unknown time; on the other hand, by outputting the second control signal to the scanning module, the tube and the data storage module of the CT scanning equipment, the scanning module, the tube and the data storage module are controlled to perform the target response action, so as to avoid the occurrence of problems such as damage to the CT scanning equipment, data loss and inability of the patient to leave safely due to the accidental power failure of the power supply equipment. In addition, the present invention combines the predicted power outage probability data of the grid power supply equipment with the collected real-time status data of the grid power supply equipment, and then controls the action of the CT scanning system with the corresponding control signal to ensure the accuracy of the determined status of the grid power supply equipment, thereby avoiding the sudden power outage of the grid power supply equipment, which may cause damage to the CT scanning equipment, data loss, and the inability of patients to leave safely.

[0072] Based on the above embodiments, Figure 3 Another power-off protection control method for CT scanning equipment provided by the embodiment of the present disclosure is as follows: Figure 3 As shown, the CT scanning equipment power-off protection control method further includes:

[0073] S140, generating a third control signal to the second switch module so that the emergency power supply receives the electrical signal output by the backup power supply, and generating a fourth control signal to the third switch module so that the non-emergency power supply is disconnected from the backup power supply.

[0074] Among them, the emergency electrical equipment power supply provides power for the scanning module, the tube and the data storage module.

[0075] In a specific implementation, when the grid power supply device is online, the main power supply of the CT scanning device receives the electrical signal of the grid power supply device, and then supplies power to the main power supply of the CT scanning device. When the grid power supply device is offline, the main power supply of the CT scanning device receives the electrical signal of the backup power supply, and then supplies power to the main power supply of the CT scanning device.

[0076] Combination Figure 2B , by setting the main power supply of the CT scanning device to be electrically connected to the power supply of the emergency power supply through the second switch module, and the main power supply of the CT scanning device to be electrically connected to the power supply of the non-emergency power supply through the third switch module. When the main power supply of the scanning device is electrically connected to the power supply device of the power grid through the first switch module, the main power supply of the CT scanning device supplies power to each module of the CT scanning device. When the main power supply of the scanning device is electrically connected to the backup power supply through the first switch module, the third control signal is output to the second switch module so that the power supply of the emergency power supply receives the electrical signal output by the main power supply of the CT scanning device, and the fourth control signal is output to the third switch module, so that the power supply of the non-emergency power supply does not receive the electrical signal output by the main power supply of the CT scanning device, and the scanning module, the tube and the data storage module of the CT scanning device are powered by the power supply of the emergency power supply, so that the scanning module, the tube and the data storage module can perform the target response action, thereby avoiding the damage of the CT scanning device, the loss of data and the inability of the patient to leave safely. In addition, the power supply of non-emergency electrical equipment is disconnected from the main power supply of the CT scanning equipment to avoid excessive consumption of the backup power supply, which would cause the backup power supply to be consumed too quickly and unable to supply power to the emergency electrical equipment normally, thereby causing damage to the CT scanning equipment, data loss, and patients being unable to leave safely.

[0077] Based on the above embodiments, Figure 4 Another power-off protection control method for CT scanning equipment provided by the embodiment of the present disclosure is based on the above embodiment. Figure 4 As shown, the CT scanning equipment power-off protection control method further includes:

[0078] S150, obtaining response status information of the scanning module, the tube and the data storage module.

[0079] After step S130 generates the second control signal to the scanning module, the tube and the data storage module of the CT scanning device, the scanning module, the tube and the data storage module of the CT scanning device respond to the second control signal and perform the target response action.

[0080] The scanning module includes a scanning frame and a scanning bed.

[0081] In a specific implementation, obtaining response status information of the scanning module, the tube, and the data storage module includes: obtaining position information and angle information of the scanning gantry, status information of the tube, and data status information of the data storage module; when the position information of the scanning gantry satisfies the first preset position information and the angle information of the scanning gantry satisfies the first preset angle information, obtaining the position information and angle information of the scanning bed.

[0082] First, the position information and angle information of the scanning gantry, the status information of the tube and the data status information of the data storage module are obtained, and then when the position information of the scanning gantry meets the first preset position information and the angle information of the scanning gantry meets the first preset angle information, the position information of the scanning bed is obtained. That is, after the second control signal is output to the scanning module of the CT scanning device, the scanning module first executes the control of the scanning gantry to run to the first preset position information and the first preset angle information, the first preset position information and the first preset angle information are the position information and angle information corresponding to the scanning gantry in the initial state, and then after the scanning gantry runs to the first preset position information and the first preset angle information, the scanning bed is then controlled to run to the second preset position information and the second preset angle information, the second preset position information and the second preset angle information are the position information and angle information corresponding to the scanning bed in the initial state, so that the scanning object can be safely evacuated from the scanning bed, and the influence of the scanning gantry on the scanning object is avoided when the scanning object gets off the scanning bed.

[0083] S160: Determine whether to generate a fifth control signal to a main power supply of the CT scanning device according to the response status information of the scanning gantry, the scanning bed, the tube, and the data storage module.

[0084] When the position information of the scanning module meets the preset position information, the status information of the tube is the closed status information and the response status information of the data storage module is that the data storage is completed, a fifth control signal is generated to the main power supply of the CT scanning device to control the main power supply of the CT scanning device to power off through the fifth control signal.

[0085] When the scanning module of the CT scanning device runs to the preset position information corresponding to the initial state, the tube state information is in the closed state, and the data storage module has completed data storage. At this time, by outputting the fifth control signal to the main power supply of the CT scanning device, the main power supply of the CT scanning device is powered off, and the overall power-off operation of the CT scanning device is completed. On the basis of ensuring the safe power-off of the CT scanning device, the data of the CT scanning device can be stored and the patient can leave safely.

[0086] On the basis of the above embodiments, the embodiments of the present disclosure further provide a power-off protection control device for a CT scanning device, which is applied to a CT scanning system. The CT scanning system at least includes a CT scanning device, a main power supply of the CT scanning device, a first switch module, and a backup power supply.
