Fig. 1 is an exemplary configuration diagram of a power supply device of an X-ray apparatus according to the present invention.
As can be seen from fig. 1, the power supply device 10 of the X-ray apparatus 40 comprises:
a contactor 30 including a contact 32 and a coil 31;
an uninterruptible power supply 20;
a current on-off control device 26 adapted to control the on-off of the current in the coil 31;
the contact 32 is arranged between an input power supply and the uninterrupted power supply 20, the uninterrupted power supply 20 is connected with a power supply input end of the X-ray equipment 40, a control end of the current on-off control device 26 is connected with a control signal output end of the X-ray equipment 40, and the rated power of the uninterrupted power supply 20 is larger than or equal to the maximum power of the X-ray equipment 40.
The contactor 30 may be implemented as a three-phase ac contactor. For example, as shown in fig. 1, the number of the contacts 32 is 3, and each of the contacts 32 is connected to a single-phase input of a three-phase power source (i.e., an input power source). The contacts 32 are normally closed (when the coil 31 is not energized) to establish an electrical connection between the input power source and the ups 20 to draw power from the input power source into the power supply 10.
The current on-off state of the coil 31 may affect the state of the contacts 32, wherein the contacts 32 are closed when the coil 31 is not energized and the contacts 32 are open when the coil 31 is energized. When the control terminal of the current on-off control device 26 receives a ready-to-scan signal from the control signal output terminal of the X-ray apparatus 40, the current on-off control device 26 turns on the current of the coil 31, so that the contact 32 is opened to cut off the electrical connection between the input power and the uninterruptible power supply 20.
In one embodiment, when the control terminal of the current on-off control device 26 receives a scan end signal or a standby (stand by) signal from the control signal output terminal of the X-ray apparatus 40, the current on-off control device 26 opens the current of the coil 31, so that the contact 32 is closed to make the electrical connection between the input power and the uninterruptible power supply 20.
Therefore, when the control terminal of the current on-off control device 26 receives the scanning end signal or the standby signal from the control signal output terminal of the X-ray apparatus 40, the current on-off control device 26 is in a state of causing the coil 31 to be in an unpowered state; when the control terminal of the current on-off control means 26 receives a ready-to-scan signal from the control signal output terminal of the X-ray device 40, the current on-off control means 26 is in a state such that the coil 31 is in an energized state.
The ups 20 includes an energy storage device, and is mainly used to provide uninterrupted power to devices with high requirements for power stability. When the X-ray device 40 is in the standby mode, the uninterruptible power supply 20 stabilizes an input power (e.g., commercial power) and supplies the stabilized input power to the X-ray device 40, where the uninterruptible power supply 20 is similar to an ac power stabilizer, and the input power also charges an energy storage device in the uninterruptible power supply 20; when the X-ray device 40 is in the scan mode, the ups 20 immediately supplies dc power of its battery to the X-ray device 40 by an inverter conversion method, so that the load can maintain normal operation and protect the load software and hardware from damage, wherein the rated power of the ups 20 is greater than or equal to the maximum power of the X-ray device 40. Furthermore, the ups 20 typically provides protection against over-voltage or under-voltage.
Specifically, the method comprises the following steps:
(1) before the X-ray device 40 is turned on and before a ready-to-scan signal is sent, the control end of the current on-off control device 26 receives a standby signal from a control signal output end (for example, a control host of the X-ray device) of the X-ray device 40, the current on-off control device 26 controls the coil 31 to be in an unpowered state, so that the contact 32 of the contactor 30 is in a closed state, the contactor 30 is connected with the electrical connection between the input power supply and the uninterruptible power supply 20, and at this time, the input power supply charges the uninterruptible power supply 20 on one hand and provides standby capacity for the X-ray device 40 on the other. The capacity of the input power supply is larger than or equal to the sum of the standby capacity of the X-ray equipment, the working loss of the uninterrupted power supply and the charging capacity of a battery in the uninterrupted power supply.
(2) When the X-ray equipment 40 needs to execute the scanning work, the control signal output end of the X-ray equipment 40 sends out a scanning preparation signal. After the current on-off control device 26 receives the ready-to-scan signal, the control coil 31 is in an energized state, the contact 32 is disconnected, the contactor 30 is in a disconnected state to disconnect the electrical connection between the input power and the uninterruptible power supply 20, and at this time, the uninterruptible power supply 20 replaces the input power supply to provide the capacitance for the X-ray device 40, and as the rated power of the uninterruptible power supply 20 is greater than or equal to the maximum power of the X-ray device 40, the uninterruptible power supply 20 can meet the scanning requirement of the X-ray device 40.
(3) And when the X-ray equipment 40 finishes the scanning work, the control signal output end of the X-ray equipment sends out a scanning end signal. The on/off current control device 26 controls the coil 31 to be in the unpowered state, so that the contacts 32 of the contactor 30 are in the closed state, and the contactor 30 makes the electrical connection between the input power source and the uninterruptible power supply 20, at which point the input power source is restored to: on the one hand, to charge the ups 20 and on the other hand to provide standby capacity for the X-ray device 40.

For example, the three-phase controllable rectification circuit includes a three-phase half-wave controllable rectification circuit, a three-phase half-controlled bridge rectification circuit or a three-phase full-controlled bridge rectification circuit, etc.
Preferably, the inverter module 22 includes an inverter circuit. An inverter Circuit (Inverting Circuit) corresponds to a rectifier Circuit, and converting direct current into alternating current is called inversion. According to the nature of the dc power supply, the inverter circuit can be divided into a voltage-type inverter circuit powered by a voltage-type dc power supply and a current-type inverter circuit powered by a current-type dc power supply. The inverter circuit can be divided into the following parts according to the devices of the main circuit: the full-control type inverter circuit consists of full-control type devices with self-turn-off capability; a semi-controlled inverter circuit composed of semi-controlled devices (such as common thyristors) without breaking capability, etc. The inverter circuit is generally implemented as a three-phase inverter circuit, such as a three-phase voltage-type inverter circuit or a three-phase current-type inverter circuit.
The above exemplary descriptions describe typical examples of the rectifier module 21 and the inverter module 22, and those skilled in the art will appreciate that such descriptions are merely exemplary and are not intended to limit the scope of the embodiments of the present invention.

The first and second circuit breakers 24 and 25 are in a closed state by default. When serious overload or short circuit, undervoltage and other faults occur, the first circuit breaker 24 and the second circuit breaker 25 can automatically break the circuit.
In one embodiment, the current on-off control device 26 comprises: a switch or a relay.
In one embodiment, the X-ray device includes an X-ray machine, an electronic computed tomography device, and a direct digital imaging device, among others.

Fig. 2 is a schematic diagram of the power supply system of the present invention for supplying power to the X-ray device in the standby mode.

When the coil 31 is not energized, the contacts 32 are closed, and when the coil 31 is energized, the contacts 32 are open.
When the X-ray device 40 is in a standby mode (e.g., the X-ray device 40 is turned on until the X-ray device 40 sends a ready-to-scan signal), the control terminal of the current on-off control device 26 receives a standby signal (e.g., a low level signal) from the control signal output terminal of the X-ray device 40, and the current on-off control device 26 controls the coil 31 to be in a power-off state (e.g., opens the power supply circuit of the control coil 31) based on the low level signal. Since the control coil 31 is in the unpowered state, the contact 32 of the contactor 30 is in the closed state, so as to connect the electrical connection between the input power source and the ups 20, at this time, the input power source charges the ups 20 on the one hand, and provides standby capacity for the X-ray device 40 on the other hand.
In fig. 2, the moving direction of the power supplied by the input power source is shown by a dotted arrow. It can be seen that after the current provided by the input power source is rectified by the rectifying module 21, a part of the rectified current charges the ups 20, and the rest of the rectified current is inverted by the inverting module 22 to provide standby capacity for the X-ray device 40. At this time, the standby power required for the X-ray device 40 is small, and the input power supplies the X-ray device 40 through the main circuit power supply mode of the uninterruptible power supply 20.

When the coil 31 is not energized, the contacts 32 are closed, and when the coil 31 is energized, the contacts 32 are open.
When the X-ray device 40 is in the ready-to-scan mode, a ready-to-scan signal is emitted by the control signal output of the X-ray device 40. After the current on-off control device 26 receives the ready-to-scan signal, the control coil 31 is in an energized state, so that the contactor 30 becomes an open state to disconnect the electrical connection between the input power and the uninterruptible power supply 20, at this time, the uninterruptible power supply 20 replaces the input power supply to provide the capacitance for the X-ray device 40, and as the rated power of the uninterruptible power supply 20 is greater than or equal to the maximum power of the X-ray device 40, the uninterruptible power supply 20 can meet the scanning requirement of the X-ray device 40.
In fig. 3, the moving direction of the power supplied by the input power source is shown by a dotted arrow. It can be seen that the ups 20 switches from the main circuit power mode to the battery power mode, and the ups 20 replaces the input power to provide power to the X-ray device 40.
And when the scanning is finished, the control signal output end of the X-ray equipment sends out a scanning finishing signal. The on/off current control device 26 controls the coil 31 to be in the unpowered state so that the contacts 32 of the contactor 30 are in the closed state to make the electrical connection between the input power source and the ups 20, at which point the input power source is restored to: on the one hand, to charge the ups 20 and on the other hand to provide standby capacity for the X-ray device 40. That is, the uninterruptible power supply 20 switches from the battery supply mode to the main circuit supply mode.
