It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0020] Figure 1 This is a schematic diagram of a radiation excitation control system provided in an embodiment of the present invention. Figure 1 As shown, the radiation excitation control system 100 includes: a wireless signal transmitting module 101, a wireless signal receiving module 102, a radiation excitation control module 103, and a radiation device 104, wherein... The wireless signal transmitting module 101 is used to generate an excitation signal in response to a triggering operation for a ray excitation event, and to transmit the excitation signal to the wireless signal receiving module 102 via wireless transmission. The wireless signal receiving module 102 is used to receive the excitation signal and send the excitation signal to the X-ray excitation control module 103; The X-ray excitation control module 103 is used to control the X-ray device 104 to perform X-ray excitation in a preset mode in response to the detection of an excitation signal.

[0021] The wireless signal transmitting module 101 and the wireless signal receiving module 102 communicate wirelessly, allowing operators to remotely control the radiation device and reduce the harm caused by radiation. Optionally, the wireless transmission method includes at least one of Wi-Fi, Zigbee, and Bluetooth.

[0022] The wireless signal transmitting module 101 and the wireless signal receiving module 102 are paired one-to-one to avoid signal interference from other wireless devices in the environment and reduce the risk of false triggering. Optionally, the wireless signal transmitting module 101 and the wireless signal receiving module 102 communicate via an independent wireless transmission protocol. For example, when the wireless signal transmitting module 101 and the wireless signal receiving module 102 communicate using Bluetooth, they can establish a communication connection through an independent Bluetooth protocol to ensure the security and reliability of communication and prevent signal interference or theft.

[0023] In this embodiment of the invention, before the operator triggers the radiation excitation event, the wireless signal transmitting module 101 needs to select a wireless transmission method (such as Bluetooth, Wi-Fi, Zigbee, etc.) that matches the wireless signal receiving module 102 and send a connection request. After receiving the connection request, the wireless signal receiving module 102 establishes a communication connection with the wireless signal transmitting module 101 through an independent wireless transmission protocol, completing the preparation work for the radiation excitation event. Afterwards, the operator can trigger the radiation excitation event according to actual needs. In response to the triggering operation for the radiation excitation event, the wireless signal transmitting module 101 generates an excitation signal and sends the excitation signal to the wireless signal receiving module 102. It should be noted that due to the radiation excitation requirements of the radiation device, the complex radiation excitation control operation cannot be completed by the wireless signal transmitting module 101 and the wireless signal receiving module 102 alone. Therefore, after the wireless signal receiving module 102 receives the excitation signal, it also needs to send the excitation signal to the radiation excitation control module 103. In response to detecting the excitation signal, the radiation excitation control module 103 controls the radiation device 104 to perform radiation excitation in a preset mode. The preset mode can be set by the operator according to actual needs, and this embodiment of the invention does not limit this. The excitation signal generated by the wireless signal transmitting module is received by the wireless signal receiving module and forwarded to the radiation excitation control module. The radiation excitation control module then controls the radiation device to perform radiation excitation based on the excitation signal, enabling remote and precise control of radiation excitation and reducing the harm caused by radiation to the operator.

[0024] Optionally, see Figure 1The wireless signal transmitting module 101 is located outside the lead room and is specifically used to: generate an excitation signal in response to detecting that both the preparation button and the excitation button on the wireless signal transmitting module 101 are pressed, and to transmit the excitation signal from outside the lead room to the wireless signal receiving module 102 inside the lead room via wireless transmission.

[0025] In this embodiment of the invention, the wireless signal transmitter 101 is located outside the lead room. The operator can trigger a radiation excitation event using the wireless signal transmitter 101 outside the lead room. Specifically, the operator can trigger the radiation excitation event by simultaneously pressing the two-stage button on the wireless signal transmitter 101, namely the prepare button and the trigger button. For example, Figure 2 A schematic diagram of a wireless signal transmitting module is shown. Subsequently, in response to detecting that both the ready button and the trigger button on the wireless signal transmitting module 101 are pressed, the wireless signal transmitting module 101 generates a trigger signal and transmits the trigger signal wirelessly to the wireless signal receiving module 102 inside the lead room. By providing a two-stage button on the wireless signal transmitting module 101 and generating the trigger signal when both the ready button and the trigger button are pressed, the risk of accidental triggering can be prevented.

[0026] Optionally, see Figure 3 The X-ray excitation control module 103 includes a pitch angle control unit 310, a rotation speed control unit 320, and a X-ray excitation control unit 330, wherein... The pitch angle control unit 310 is used to adjust the pitch angle of the X-ray device 104 to a preset angle in response to the detection of an excitation signal. The rotation speed control unit 320 is used to control the rotation speed of the X-ray device 104 to reach the preset rotation speed after the pitch angle of the X-ray device 104 is adjusted to the preset angle. The X-ray excitation control unit 330 is used to control the X-ray device 104 to perform X-ray excitations to a preset number of times within the time of one rotation while the rotation speed of the X-ray device 104 reaches a preset rotation speed.

[0027] In this embodiment of the invention, due to the radiation excitation requirements of the radiation device, the complex radiation excitation control operation cannot be completed by the wireless signal transmitting module 101 and the wireless signal receiving module 102 alone. Therefore, a radiation excitation control module 103 is needed to control the radiation device 104 for radiation excitation. Specifically, the radiation excitation control module 103 includes a pitch angle control unit 310, a rotation speed control unit 320, and a radiation excitation control unit 330. After detecting the excitation signal sent by the wireless signal receiving module 102, in response to the detected excitation signal, the pitch angle control unit 310 adjusts the pitch angle of the radiation device 104 to a preset angle, ensuring that the radiation device 104 can complete the rotation at a designated position. The preset angle can be set by the operator according to the actual situation, and this embodiment of the invention does not limit this setting. After the pitch angle of the radiation device 104 is adjusted to the preset angle, the rotation speed control unit 320 controls the rotation speed of the radiation device 104 to reach the preset rotation speed. Simultaneously, the radiation excitation control unit 330 controls the number of radiation excitations performed by the radiation device 104 within one rotation time to reach the preset number of excitations. The preset rotation speed and preset number of excitations can be set by the operator according to actual needs, such as a preset rotation speed of 7 degrees per second and a preset number of excitations of 600 times. This embodiment of the invention does not limit these settings.

[0028] Optionally, the rotation speed control unit 320 is specifically used to: after the pitch angle of the X-ray device 104 is adjusted to a preset angle, start the rotary motor through a driver to make the X-ray device 104 rotate; and determine the motor speed of the rotary motor through an encoder, and keep the rotation speed of the X-ray device 104 at a preset rotation speed by adjusting the motor speed.

[0029] In this embodiment of the invention, after the pitch angle of the X-ray device 104 is adjusted to a preset angle, the rotation speed control unit 320 controls the rotation speed of the X-ray device 104 to reach the preset rotation speed. Specifically, the rotation speed control unit 320 starts the rotation motor through a driver, causing the X-ray device 104 to rotate. It also determines the current rotation position information of the rotation motor through an encoder, and then determines the motor speed based on the current rotation position information. By adjusting the motor speed, the rotation speed of the X-ray device 104 is maintained at the preset rotation speed. For example, Figure 4 A schematic diagram of the operation of a rotation speed control unit is shown.

[0030] Optionally, see Figure 3 The X-ray excitation control module 103 also includes a first X-ray termination unit 340; wherein, the first X-ray termination unit 340 is used to determine whether the X-ray excitation control module 103 detects an excitation signal according to a preset period, and if not, control the X-ray device 104 to terminate the X-ray excitation.

[0031] In this embodiment of the invention, due to the rotational speed requirements of the X-ray device 104, the current rotational position information of the rotating motor needs to be determined in real time via an encoder. Simultaneously, the X-ray emitter in the X-ray device 104 must be continuously excited during the rotation of the X-ray device 104. Therefore, the excitation signal must be continuously present during the rotation of the X-ray device 104 and the X-ray excitation process. The X-ray excitation control module 103 also includes a first X-ray termination unit 340. The first X-ray termination unit 340 determines whether the X-ray excitation control module 103 has detected an excitation signal according to a preset period. If not, it controls the X-ray device 104 to terminate the X-ray excitation, ensuring that the X-ray excitation process is strictly controllable. The preset period can be set by the operator according to actual needs, such as 10ms; this embodiment of the invention does not limit this setting.

[0032] Optionally, see Figure 3 The X-ray excitation control module 103 also includes a second X-ray termination unit 350; wherein the second X-ray termination unit 350 is used to monitor the working status of the X-ray device 104 and control the X-ray device 104 to terminate X-ray excitation when the working status of the X-ray device 104 is abnormal; wherein the working status includes at least one of X-ray intensity stability and X-ray tube temperature.

[0033] In this embodiment of the invention, the radiation excitation control module 103 further includes a second radiation termination unit 350. The second radiation termination unit 350 monitors the working status of the radiation device 104 in real time, including radiation intensity stability, radiation tube temperature, etc., and controls the radiation device 104 to terminate radiation excitation when the working status of the radiation device 104 is abnormal (such as the radiation tube temperature exceeding the normal range), so as to ensure the safety of radiation excitation.

[0034] Optionally, see Figure 5 The X-ray excitation control system 100 also includes a robot operating platform 105; wherein, the robot operating platform 105 is used to adjust the operating posture of the robot operating platform 105 according to a preset operating program while the X-ray excitation control module 103 controls the X-ray device 104 to perform X-ray excitation; wherein, the operating posture includes the robotic arm posture of the robot operating platform 105.

[0035] In this embodiment of the invention, the X-ray excitation control system 100 further includes a robot operating platform 105. While the X-ray excitation control module 103 controls the X-ray device 104 to perform X-ray excitation, the robot operating platform 105 adjusts its own operating posture according to a preset operating program, including the position of its robotic arm, to coordinate with the operator. Simultaneously, the operator can also observe the operating area and the working status of the X-ray device in real time through the monitoring device on the robot operating platform 105, and make timely adjustments to ensure the safety and success rate of the operation.

[0036] Based on the same inventive concept, this invention also provides a method for controlling radiation excitation. Figure 6 This is a flowchart illustrating a radiation excitation control method provided in an embodiment of the present invention, as shown below. Figure 6 As shown, the method includes the following steps: S110. The wireless signal transmitting module responds to the triggering operation for the ray excitation event, generates an excitation signal, and sends the excitation signal to the wireless signal receiving module via wireless transmission. S120: Receive the excitation signal through the wireless signal receiving module and send the excitation signal to the X-ray excitation control module; S130. In response to the detection of the excitation signal, the X-ray excitation control module controls the X-ray device to perform X-ray excitation in a preset mode.

[0037] The radiation excitation control method provided in this invention involves a wireless signal transmitting module generating an excitation signal in response to a triggering operation for a radiation excitation event, and then wirelessly transmitting the excitation signal to a wireless signal receiving module. The wireless signal receiving module receives the excitation signal and sends it to a radiation excitation control module. Upon detecting the excitation signal, the radiation excitation control module controls the radiation device to perform radiation excitation in a preset mode. This technical solution, by receiving the excitation signal generated by the wireless signal transmitting module and forwarding it to the radiation excitation control module, allows for remote and precise control of radiation excitation, reducing the harm caused to operators by radiation.
