The X-ray generator power-off protection control method according to the exemplary embodiment of the present application will be described with reference to fig. 1 to 3.
Referring to fig. 1, a flowchart of a power-off protection control method for an X-ray generator according to an embodiment of the present application is provided. As shown in fig. 1, may include:
and S101, detecting a control signal by the X-ray generator power-off protection control device.
The X-ray generator power-off protection control device (hereinafter referred to as a control device) is used for detecting a control signal, and the control signal is used for turning off or turning on the X-ray generator. In a specific implementation, the control device may receive a control signal sent by the X-ray apparatus, where the control signal may be a level signal. For example, if a high signal is received, the signal is a signal for turning off the X-ray generator; if a low level signal is received, the signal is a signal for starting the X-ray generator. In a specific implementation, the control device may further receive a control signal sent by a remote server, where the control signal is specifically a control command, and a specified field carried by the command is used to indicate to turn off or turn on the X-ray generator. For example, if the value of the specified field is 1, the X-ray generator is turned off; if the value of the designated field is 0, the X-ray generator is turned on. In this way, remote control of the X-ray generator can be achieved. Of course, the above is only an exemplary illustration, and the control signal may be in other implementations.
S102, after the control device determines that the control signal is a signal for turning off the X-ray generator, a power-off preparation program is triggered.
The control means determining whether the control signal is a signal for turning off the X-ray generator may include: the control means determines whether a high level signal is detected; and if so, determining the control signal as a signal for closing the X-ray generator. Alternatively, the control means determining whether the control signal is a signal for turning off the X-ray generator may include: the control device judges whether the value of the designated field of the received control command is used for indicating a signal for turning off the X-ray generator; and if so, determining the control signal as a signal for closing the X-ray generator.
Wherein triggering the power-off preparation program may include: and stopping the work of the anode of the X-ray generator, executing heat dissipation treatment on the X-ray generator, and recording the running state of the X-ray generator. According to the embodiment of the application, after the control signal is determined to be the signal for closing the X-ray generator, the power is not cut off immediately, and the heat dissipation treatment is performed on the X-ray generator after the anode of the X-ray generator stops working. For example, rapid heat dissipation may be achieved by increasing the fan speed. In addition, the current operating state of the X-ray generator can also be recorded in order to achieve a fast state recovery. The operating state may include: standby state, ready to operate state, operating state, shutdown state, restart state, etc.
S103, acquiring the state information of the X-ray generator, and judging whether the X-ray generator is in a power-off state.
The control means may acquire the state information of the X-ray generator by sending a request to the X-ray generator and receiving the state information. Of course, the X-ray generator may also send status information to the control device in real time. The state information of the X-ray generator can be parameter information of the X-ray generator, such as temperature information of the X-ray generator. The state information of the X-ray generator may also be operational state information of the X-ray generator. The operating state information may include a standby state, a ready-to-operate state, an operating state, a shutdown state, a restart state, and the like.
When the state information of the X-ray generator includes temperature information of the X-ray generator, the judging whether the X-ray generator is in a power-off state includes: judging whether the temperature of the X-ray generator is smaller than a set temperature threshold value or not; and if the temperature of the X-ray generator is less than the set temperature threshold, determining that the X-ray generator is in a power-off state.
And S104, if the X-ray generator is determined to be in a power-off state, the control device controls the X-ray generator to switch off a power supply.
In this application, replace the mode of prior art direct disconnection X ray generator power, when receiving the signal of closing X ray generator, postpone to the outage of X ray generator, when judging that X ray generator is in the outage state, for example when its temperature is less than the temperature threshold that sets up, confirm that its heat dissipation is accomplished and be in the outage state, control X ray generator cuts off the power, has reached the effective protection to X ray generator, has reduced the harm to X ray generator, has prolonged its life.
In one possible implementation, the controlling the X-ray generator to turn off the power supply includes: sending a control signal to a power switch device of an X-ray generator for disconnecting a power supply of the X-ray generator; the power switch device is a contactor, a controller or a silicon controlled rectifier.
It should be noted that, in the conventional method, as soon as the switch is touched by mistake, the system is immediately powered off, and the initialization of the X-ray generator or the X-ray device is resumed for a long time. In order to prevent inconvenience caused by false touch operation, the state of the X-ray generator can be quickly recovered when a false touch event occurs, and waiting time is reduced.
In a possible implementation manner, if a signal for starting the X-ray generator is detected before the X-ray generator is controlled to be powered off, a power-off termination signal is sent; and controlling the X-ray generator to recover to the running state before power-off preparation treatment according to the recorded running state of the X-ray generator. For example, in some cases, the detected control signal is used to switch the device from a normal operating state to an off state, which may be caused by a false touch operation. In other cases, the false touch recovery process may be entered immediately if the device has just been shut down and needs to be turned back on immediately. For example, when a change in the control signal is detected, the power-down process may be terminated in preparation for restoring the operating state of the X-ray generator. For example, the anode of the X-ray generator can be turned on again, records can be inquired, and the X-ray generator is controlled to be restored to the operation state before the power-off preparation treatment according to the operation state of the X-ray generator. For example, if the operation state of the X-ray generator before the power-off preparation process is the working state, the X-ray generator can be directly restored to the working state through quick restoration without re-entering the preparation working state and completing the preparation working again, thereby greatly saving the waiting time and improving the working efficiency.
In some cases, an X-ray generator failure may occur, that is, the X-ray generator is judged to be in a power-off state, and after receiving a power-off signal for a period of time, the X-ray generator is not in the power-off state, and then the X-ray generator may be controlled to be powered off forcibly.
In some embodiments, the delayed power-off time may be determined according to the acquired state information of the X-ray generator; judging whether the time delay power-off time is reached; the determining whether the X-ray generator is in a power-off state according to the state information of the X-ray generator includes: and if the time delay power-off time is not reached, determining whether the X-ray generator is in a power-off state or not according to the state information of the X-ray generator. Further, if the time delay power-off time is judged to be reached, updating the time delay power-off time; and controlling the X-ray generator to cut off the power supply after the updated delayed power-off time is reached. For example, if it is determined that the current temperature of the X-ray generator is 500 degrees, and it takes 5 seconds for complete heat dissipation, the delayed power-off time T may be set to be greater than or equal to 5S, for example, 8S. If the X-ray generator is detected to be in a power-off state within the time 8S, power-off processing is executed. If the time 8S is exceeded, the time may be extended by another time, such as a delay of 4S. And if the X-ray generator is still in the uninterruptible state after 4S, forcibly controlling the X-ray generator to disconnect the power supply. Of course, the foregoing is merely exemplary and is not to be construed as limiting the present application.
In the embodiment of the present application, after receiving a signal for turning off the X-ray generator, it may be determined whether the X-ray generator is in a power-off state according to the acquired state information of the X-ray generator. When the X-ray generator is in a power-off state, the power supply is cut off, so that the normal power-off of the X-ray generator is ensured, the damage to the performance of the X-ray generator is reduced, and the service life of the X-ray generator is prolonged. In addition, if the signal for turning off the X-ray generator is caused by false touch, the X-ray generator cannot be powered off immediately, and the state can be quickly recovered, so that the restarting waiting time is reduced, and the processing efficiency is improved. In addition, the embodiment of the application can also realize forced power-off when the X-ray generator fails, so that resource waste is reduced.

The CT scanning device starts to resume normal operation, for example: and restarting the anode of the bulb tube, inquiring the running record and recovering the state before power failure. The system operates normally and waits for a switching signal.

After receiving the shutdown signal, the monitoring of the running state of the bulb and the pre-estimation of the shutdown time are completed, and the shutdown state is displayed through a rack display screen or other human-computer interfaces. When the bulb tube enters a power-off state, the control contactor cuts off the bulb tube power supply, so that the bulb tube power supply is normally powered off. Through the human-computer interface, an operator can also conveniently know the current running state of the CT scanning equipment. The shutdown signal can be generated in the CT scanning equipment rack, and can also be generated by a remote server, so that remote control is realized. If the switching signal is triggered by mistake, the CT scanning equipment of the system can not be powered off immediately, and when the switch is recovered to be normal, the CT scanning equipment system can be recovered to be normal operation quickly. The bulb tube of the CT scanning equipment is protected by a delayed power-off method. The protection function of the bulb tube power-off process, the quick recovery function after the shutdown switch is touched by mistake and the forced power-off function of the bulb tube fault are realized.
