[0002] The X-ray tube of a medical X-ray machine is mounted on a frame, and its rotating anode and filament control are typically controlled by a high-voltage generator. During exposure, the X-ray tube generates X-rays, but operators cannot closely observe its operation. Related technical solutions require integrating all components into a sealed enclosure; however, the frequent activation of the X-ray tube's filament heating and rotating anode drive during testing makes the connection method unsuitable for achieving the desired testing functionality. Summary of the Invention

[0003] The purpose of this invention is to provide a testing apparatus and equipment for X-ray tubes. The X-ray tube and control circuit are designed separately, and the fluoroscopy and exposure of the X-ray tube are simulated through two switching modules. No X-rays are generated during the test, thus improving the safety of the testing process.

[0044] The core of this invention is to provide a testing apparatus and equipment for X-ray tubes. The X-ray tube and control circuit are designed separately, and the fluoroscopy and exposure of the X-ray tube are simulated through two switching modules. No X-rays are generated during the test, improving the safety of the testing process. Users only need to control the first and second switching modules to control the X-ray tube, improving the ease of use of the test.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Figure 1 This is a schematic diagram of the structure of an X-ray tube testing apparatus provided by the present invention. The X-ray tube testing apparatus includes:

[0047] Power module 1 is connected to control circuit 4 and is used to supply power to control circuit 4.

[0048] First switch module 2, first switch module 2 is connected to control circuit 4;

[0049] The second switch module 3 is connected to the control circuit 4;

[0050] The control circuit 4 is connected to the X-ray tube 5. In response to the first switch module 2 being closed, it controls the X-ray tube 5 to perform simulated exposure. In response to the second switch module 3 being closed, it controls the X-ray tube 5 to perform simulated fluoroscopy.

[0051] X-ray tube 5.

[0052] The X-ray tube 5 of a medical X-ray machine is mounted on the frame, and its rotating anode and filament control are usually handled by a high-voltage generator. During exposure, the X-ray tube 5 generates X-rays, but operators cannot closely observe its operation. To improve safety and ease of operation, the X-ray tube 5 and part of the control circuit 4 can be designed separately to control only the operation of the filament and rotating anode (without generating X-rays). This eliminates the need for radiation protection for operators, facilitates the identification of the X-ray tube 5, and allows for the testing of the rotating anode startup and operation, thus ensuring operational safety. This invention, by removing the high-voltage inverter simulation, retaining the X-ray tube filament and anode control circuit 4, removing the outer shell of the X-ray tube to make the entire tube core clearly visible, and using a circuit lock to prevent simultaneous use of photography and fluoroscopy functions, constructs a safe, intuitive, and educational X-ray tube 5 filament and anode simulation test system. This completely avoids radiation risks, reduces equipment complexity and maintenance costs, and significantly improves teaching applicability and operational safety.

[0053] In the X-ray tube 5 teaching experiment system, the essence of the simulated fluoroscopy function and the simulated exposure function is to reproduce the filament heating state and anode rotation state of the real X-ray machine in two working modes through circuit control. However, since the system does not generate high voltage (i.e. does not generate X-rays), it only simulates the electrical and mechanical performance of the preparation stage and the operating state, and does not simulate the final physical process of ray generation.

[0054] Fluoroscopy is a continuous, low-dose X-ray examination mode (such as gastrointestinal examination). In real equipment, a small filament (small focal spot, high image clarity, but low heat capacity) is typically used, with the anode continuously rotating to emit X-rays. The simulated fluoroscopy in this system involves lighting the small filament, simulating filament heating during fluoroscopy. The rotating anode continues to operate, simulating the continuous rotation and heat dissipation during fluoroscopy. This is controlled by the second switch module 3 (foot brake); pressing the foot brake activates the mode, and releasing it stops it.

[0055] Exposure is a transient, high-dose X-ray imaging mode (such as radiography). It typically uses a large filament (large focal length, high heat capacity, and able to withstand high heat). The anode needs to be accelerated to its rated speed before exposure, and then high voltage is instantaneously applied to generate X-rays. In this system, simulated exposure involves lighting the large filament, simulating the preheating of the large focal filament before exposure. Controlled by a delay circuit, pressing the first position of the handbrake initiates the anode acceleration; after the delay time (when the simulated anode has reached its rated speed), the second position of the handbrake is engaged, and the simulated exposure begins. The system is controlled by operating the handbrake in two positions.

[0056] Specifically, the first switch module 2 and the second switch module 3 can be configured as a handbrake and a foot brake, respectively, for easy user control. The handbrake and foot brake control the anode start-up time and exposure time of the X-ray tube 5. During operation, the first switch module 2 triggers the filament and rotating anode delay circuit, putting the large filament and rotating anode into operation, and then the filament and rotating anode control circuit 4 simulates the exposure state. After releasing the first switch module 2, the second switch module 3 is pressed to enter the simulated fluoroscopy state. At this time, the small filament and rotating anode control circuit 4 is activated, keeping the small filament and rotating anode running continuously. After the experiment, the second switch module 3 is released. During operation, the operator can observe the working status of the large filament, small filament, rotating anode, and indicator lights in real time. After observation, the first switch module 2 and the second switch module 3 are released. An interlocking mechanism is provided between the control circuits 4 of the first switch module 2 and the second switch module 3, and between the control circuits 4 of the large filament and the small filament, to ensure that they cannot operate simultaneously, thereby improving the safety of equipment operation.

[0057] This application provides an X-ray tube testing apparatus, relating to the field of testing equipment, including a power supply module 1 connected to a control circuit 4; a first switch module 2 connected to the control circuit 4; a second switch module 3 connected to the control circuit 4; and a control circuit 4 connected to an X-ray tube 5. Responding to the first switch module 2 being closed, the control circuit 4 controls the X-ray tube 5 to perform simulated exposure; responding to the second switch module 3 being closed, the control circuit 4 controls the X-ray tube 5 to perform simulated fluoroscopy. The X-ray tube 5 and control circuit 4 are designed separately, and the simulation of fluoroscopy and exposure of the X-ray tube 5 is achieved through two switch modules. No X-rays are generated during the test, improving the safety of the testing process. Users only need to control the first switch module 2 and the second switch module 3 to control the X-ray tube 5, improving the ease of use of the test.

[0058] Based on the above embodiments:

[0059] Figure 2 A schematic diagram of the structure of a power module provided by the present invention;

[0060] In some embodiments, the power module 1 includes a circuit breaker K1, a bus switch K2, a transformer T1, and multiple switching power supply boxes;

[0061] The first terminal of circuit breaker K1 is connected to the AC power supply, the second terminal of circuit breaker K1 is connected to the first terminal of bus switch K2, the second terminal of bus switch K2 is connected to the primary side of transformer T1 and the AC side of each switching power supply box, and the secondary side of transformer T1 and the DC side of each switching power supply box are connected to control circuit 4.

[0062] Circuit breaker K1 and bus switch K2 are used to control power supply, transformer T1 is used to step down AC power supply and output it, and each switching power supply box is used to step down AC voltage and convert it into DC voltage before output.

[0063] S1, S2, and S3 are three switching power supply boxes, converting 220V AC to 24V DC, 9V DC, and 3V DC respectively. Transformer T1 converts 220V AC to 50V AC. Circuit breaker K1 can disconnect the circuit in case of a fault, providing circuit protection. Busbar switch K2 can be used by the user to control power module 1. It should also be noted that the busbar switch is essentially a push-button switch.

[0064] Figure 3 A schematic diagram of the structure of an X-ray tube provided by the present invention;

[0065] In some embodiments, the rotating anode of the X-ray tube 5 includes a first inductor L1, a second inductor L2 and a first capacitor C1, and the filament of the X-ray tube 5 includes a third inductor L3 and a fourth inductor L4.

[0066] The first terminal of the first capacitor C1 and the first terminal of the first inductor L1 are connected and their common terminal is used as the main winding terminal of the rotating anode. The second terminal of the first capacitor C1 and the first terminal of the second inductor L2 are connected and their common terminal is used as the phase shifting terminal of the rotating anode. The second terminal of the first inductor L1 and the second terminal of the second inductor L2 are connected and their common terminal is used as the common terminal of the rotating anode. The first terminal of the third inductor L3 and the first terminal of the fourth inductor L4 are connected and their common terminal is used as the common terminal of the filament. The second terminal of the third inductor L3 is used as the small filament terminal, and the second terminal of the fourth inductor L4 is used as the large filament terminal.

[0067] The control circuit 4 is connected to the main winding end, phase shifting end and common end of the rotating anode, the common end of the filament, the large filament end and the small filament end, respectively. Specifically, in response to the first switch module 2 being closed, it controls the rotating anode and filament to perform simulated exposure, and in response to the second switch module 3 being closed, it controls the rotating anode and filament to perform simulated X-ray.

[0068] Figure 4 A schematic diagram of a rotating anode provided by the present invention;

[0069] In the rotating anode control circuit 4, the relationship between the capacitor and the inductor is that the capacitor is connected in series with the starting winding (inductor), which generates a phase difference, thereby forming the starting torque.

[0070] Figure 5 A schematic diagram of the structure of a large filament and a small filament provided by the present invention;

[0071] Physically, the large and small filaments are two independent tungsten wire coils, with one end connected together inside the tube to form a common terminal. The other ends of the two filaments are led out independently (L terminal and S terminal). During operation, control circuit 4 uses a relay or electronic switch to select whether to connect one end of the power supply to the common terminal (C) or the other end to the desired filament terminal (L or S). This ensures that the large and small filaments will never light up simultaneously.

[0072] In actual use, the rotating anode is connected to a motor, and electrons emitted by the large and small filaments strike the rotating anode. The rotating anode applies high voltage, which in turn generates radiation. In the test process of this application, this high voltage will not be increased, so no radiation will be generated.

[0073] In some embodiments, it also includes a first connector P1 and a second connector J1;

[0074] The first and second contacts of the first switch module 2 are both connected to the second end of the first connector P1. The third contact of the first switch module 2 is connected to the first end of the first connector P1. The fourth contact of the first switch module 2 is connected to the third end of the first connector P1. The first contact of the second switch module 3 is connected to the fourth end of the first connector P1. The second contact of the second switch module 3 is connected to the fifth end of the first connector P1. The second connector J1 is connected to the port of the first connector P1 in a one-to-one correspondence. The second and fifth ends of the second connector J1 are grounded. The first, third and fourth ends of the second connector J1 are all connected to the control circuit 4.

[0075] The second and third contacts of the first switch module 2 are connected to generate a first closed signal; the first and fourth contacts of the first controllable switch are connected to generate a second closed signal; and the first and second contacts of the second controllable switch are connected to generate a third closed signal.

[0076] Pressing the handbrake to position 1 activates the main lamp filament and rotates the anode, accompanied by light and sound cues from the indicator light and buzzer. Pressing to position 2 activates the main lamp, ending the activation after a preset time of 1-10 seconds. The filament then goes out, and the anode slowly stops rotating. Pressing the foot brake activates the secondary lamp filament and rotates the anode, accompanied by light and sound cues from the indicator light and buzzer, until the foot brake is released, at which point the filament goes out and the anode slowly stops rotating.

[0077] When the handbrake is in position one closed, pin J1-1 (originally connected to a high level or pull-up) is connected to J1-2 (ground) through the closed contact, and the level is pulled low. After the control circuit 4 detects this falling edge, it determines it as the "first closing signal" and then starts the anode delay. Similarly, when the handbrake is in position two closed, J1-3 is pulled low, and when the foot brake is closed, J1-4 is pulled low.

[0078] Figure 6A schematic diagram of the structure of a first switch module and a second switch module provided by the present invention;

[0079] In some embodiments, a prompting device is also included, and the control circuit 4 includes a first control switch group, a second control switch group, and a third control switch group;

[0080] The control terminal of the first control switch group is connected to the first terminal of the second connector J1, the control terminal of the second control switch group is connected to the third terminal of the second connector J1, the control terminal of the third control switch group is connected to the fourth terminal of the second connector J1, the first terminals of the first control switch group, the first terminals of the second control switch group and the first terminals of the third control switch group are all connected to the power module 1, the second terminal of the first control switch group is connected to the headlight filament terminal, the main winding terminal of the rotating anode and the common terminal, the second terminal of the second control switch group is connected to the indicator device, and the second terminal of the third control switch group is connected to the small filament terminal, the indicator device, the main winding terminal of the rotating anode and the common terminal.

[0081] The first control switch group closes in response to the first closing signal, the second control switch group closes in response to the second closing signal, and the third control switch group closes in response to the third closing signal.

[0082] In simulated exposure mode, when the first position of the handbrake is pressed, a first closing signal is generated and transmitted to the first terminal of J1, and the first control switch group closes in response to the signal. The current from the power module 1 is supplied to the main lamp filament through the first control switch group, and at the same time, the main winding of the rotating anode is started, so that the system enters the exposure preparation state.

[0083] In the prompt and indication mode, when the handbrake is pressed to the second position, a second closing signal is generated and transmitted to the third terminal of J1, and the second control switch group closes in response to the signal. The power module 1 drives the prompting device (such as the exposure indicator light illuminating or the buzzer sounding briefly) to simulate the prompt at the moment the exposure begins.

[0084] In simulated X-ray mode, when the foot brake is pressed, a third closing signal is generated and transmitted to the fourth terminal of J1. The third control switch group closes in response to this signal. The current from power module 1 is supplied to the small filament through the third control switch group, which simultaneously drives the rotating anode to rotate continuously, thus putting the system into simulated X-ray state.

[0085] This embodiment uses three independent control switch groups to drive different load combinations. When the first closed signal (handbrake position one) arrives, the system drives the large filament and starts the anode; when the second closed signal (handbrake position two) arrives, only the prompting device is driven to simulate the exposure trigger moment; when the third closed signal (foot brake) arrives, the system switches to the small filament and maintains anode rotation. Because the three signals originate from different operating switches and are logically mutually exclusive, a safe and clear teaching simulation process is achieved.

[0086] Figure 7 A schematic diagram of a control circuit provided by the present invention;

[0087] In some embodiments, the first control switch group includes a first relay K4 and a second relay K3;

[0088] The first end of the coil of the first relay K4 and the first end of the coil of the second relay K3 are both connected to the first end of the second connector J1. The second ends of the coils of the first relay K4 and the second ends of the coils of the second relay K3 are both connected to the power supply. The fixed end of the first set of contacts of the first relay K4 is connected to the DC power supply. The normally closed end of the first set of contacts of the first relay K4 is left floating. The normally open end of the first set of contacts of the first relay K4 is connected to the fixed end of the first set of contacts of the second relay K3. The normally closed end of the first set of contacts of the second relay K3 is left floating. The normally open end of the first set of contacts of the second relay K3 is connected to the headlight filament end. The fixed end of the second set of contacts of the first relay K4 is connected to the AC power supply. The normally closed end of the second set of contacts of the first relay K4 is left floating. The normally open end of the second set of contacts of the first relay K4 is connected to the fixed end of the second set of contacts of the second relay K3. The normally closed end of the second set of contacts of the second relay K3 is left floating. The normally open end of the second set of contacts of the second relay K3 is connected to the main winding end and the common end of the rotating anode.

[0089] The first relay K4 is used to close the normally open and fixed ends of its first and second sets of contacts when its coil is energized. The second relay K3 is used to close the normally open and fixed ends of its first and second sets of contacts after a first preset time when its coil is energized.

[0090] When the first closing signal is received, the coil of the first relay K4 is immediately energized. Although the coil of the second relay K3 is connected in parallel with the first relay K4 on the same signal line, the second relay K3 or its drive circuit has a delay circuit. Therefore, after the coil of the second relay K3 is energized, it needs to wait for a first preset time, such as 0.8 seconds to 1.2 seconds, the time it takes for the simulated anode target disk to reach its rated speed before it engages.

[0091] When the handbrake is pressed to position one (the first closing signal is activated), the first relay K4 immediately engages, and the normally open terminals of the first and second sets of contacts are connected to the fixed terminals. However, since the second relay K3 has not yet engaged, the load circuit is disconnected at the contacts of the second relay K3, so neither the headlight filament nor the anode is energized at this time (or is only ready but not connected). After the first preset time (during the delay, if the anode has actually started, it has already accelerated), the second relay K3 engages after a delay: the normally open terminals of its first and second sets of contacts are connected to the fixed terminals. At this time, DC power is supplied to the headlight filament terminals through the contacts of the first relay K4 and the second relay K3; AC power is supplied to the rotating anode main winding terminals through the paths of the contacts of the first relay K4 and the second relay K3.

[0092] In some embodiments, the second control switch group includes a third relay K6 and a fourth relay K5;

[0093] The first end of the coil of the third relay K6 and the first end of the coil of the fourth relay K5 are both connected to the third end of the second connector J1. The second end of the coil of the third relay K6 and the second end of the coil of the fourth relay K5 are both connected to the power supply. The fixed end of the first set of contacts of the third relay K6 is connected to the DC power supply. The normally closed end of the first set of contacts of the third relay K6 is left floating. The normally open end of the first set of contacts of the third relay K6 is connected to the fixed end of the first set of contacts of the fourth relay K5. The normally closed end of the first set of contacts of the fourth relay K5 is connected to the prompting device. The normally open end of the first set of contacts of the fourth relay K5 is left floating.

[0094] The third relay K6 is used to close the normally open and fixed ends of its first and second sets of contacts when its own coil is energized. The fourth relay K5 is used to close the normally open and fixed ends of its first and second sets of contacts after a first preset time when its own coil is energized.

[0095] Upon receiving the second closing signal, the coil of the third relay K6 is immediately energized and engages. Although the coil of the fourth relay K5 is connected in parallel with the third relay K6, the fourth relay K5 or its drive circuit has a delay circuit. Therefore, after being energized, the coil of the fourth relay K5 needs to wait for a first preset time (this time can be consistent with the delay in the first control switch group, or set independently, for example, 0.5 seconds) before engaging.

[0096] When the handbrake is pressed to position two (the second closing signal is activated), the third relay K6 immediately engages, preparing for power supply. Since the fourth relay K5 is not yet engaged, its normally closed contact closes, indicating that the equipment should start immediately and providing a notification that exposure has begun. After a first preset time (a short, adjustable duration), the fourth relay K5 engages after a delay, its normally closed contact opening, indicating that the equipment should stop immediately.

[0097] The circuit described above enables the device to operate briefly (e.g., flash once or beep once) and then automatically stop when the second position of the handbrake is pressed. This effectively simulates the instantaneous alert sound emitted by the control panel during clinical exposure, avoiding energy waste or noise interference caused by prolonged operation of the alert device.

[0098] In some embodiments, the third control switch group includes a fifth relay K7;

[0099] The first end of the coil of the fifth relay K7 is connected to the fourth end of the second connector J1. The second end of the coil of the fifth relay is connected to the DC power supply. The fixed end of the first set of contacts of the fifth relay K7 is connected to the DC power supply. The normally closed end of the first set of contacts of the fifth relay K7 is left floating. The normally open end of the first set of contacts of the fifth relay K7 is connected to the small filament end. The fixed end of the second set of contacts of the fifth relay K7 is connected to the DC power supply. The normally closed end of the second set of contacts of the fifth relay K7 is connected to the DC power supply. The normally open end of the second set of contacts of the fifth relay K7 is connected to the indicator device. The fixed end of the third set of contacts of the fifth relay K7 is connected to the AC power supply. The normally closed end of the third set of contacts of the fifth relay K7 is left floating. The normally open end of the third set of contacts of the fifth relay K7 is connected to the main winding end of the rotating anode and the common end.

[0100] The fifth relay K7 is used to close its first set of contacts and the normally open and fixed terminals of its second set of contacts when its coil is energized.

[0101] When the third closing signal (foot brake depressed) is received, the coil of the fifth relay K7 is immediately energized and engaged. Since the perspective mode requires continuous operation, the fifth relay K7 remains engaged while the foot brake is depressed and de-energized and disconnects when the foot brake is released.

[0102] When the operator presses the foot brake (the third closing signal is activated), the coil of the fifth relay K7 is immediately energized and engages. DC power is supplied to the small filament, illuminating the small focal filament. Disconnecting the normally closed terminal and connecting the normally open terminal causes the DC power supply to illuminate the fluoroscopy indicator light, indicating the fluoroscopy status. AC power is supplied to the rotating anode main winding, and the anode begins to rotate continuously. When the foot brake is released, the fifth relay K7 is de-energized, all contacts reset, the small filament extinguishes, the fluoroscopy indicator light goes out, the anode stops rotating, and the system exits fluoroscopy mode.

[0103] In some embodiments, the second end of the coil of the fifth relay K7 is connected to the normally closed end of the third group of contacts of the first relay K4, the normally open end of the third group of contacts of the first relay K4 is left floating, the fixed end of the third group of contacts of the first relay K4 is connected to the normally closed end of the second group of contacts of the third relay K6, the normally open end of the second group of contacts of the third relay K6 is left floating, and the fixed end of the second group of contacts of the third relay K6 is connected to a DC power supply.

[0104] By connecting the normally closed contacts of the first relay K4 and the third relay K6 in series in the power supply circuit of the fifth relay K7, even if the control signal is unexpectedly activated due to a fault, as long as the first relay K4 and the third relay K6 are in the energized state (i.e., the system is in exposure preparation or exposure in progress), the fifth relay K7 cannot be energized, and the perspective mode cannot be activated. This, together with the signal source interlock (mechanical interlock of handbrake and foot brake), forms a dual protection mechanism, greatly improving the safety and reliability of the system.

[0105] The X-ray tube 5 has two operating states. The operating state is locked via circuit control, preventing the other state from operating. Only after the current operating state is closed can the next experiment be conducted.
