Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an infrared detection anti-collision device, a medical rotating U-shaped arm, a control method, and a medium. Background Technology

[0002] Rotary medical imaging equipment is widely used in the diagnosis of various human diseases. Due to the presence of rotating mechanical parts, if the patient suddenly moves during the diagnostic process and the equipment fails to detect this and take appropriate action, the rotating mechanical parts, such as the U-shaped arm, can easily collide with the patient, causing personal injury. Alternatively, the rotating mechanical parts may collide with other objects, causing damage to the rotating mechanical parts. Therefore, all rotating medical diagnostic equipment must have anti-collision detection functions.

[0003] Currently, the mainstream detection methods include capacitive sensing, pressure sensing, mechanical switch sensing, or ultrasonic and laser detection. The first three methods are contact detection, which can only detect obstacles when they come into contact with rotating mechanical parts. At this point, the human body or the rotating mechanical parts may have already been damaged due to direct collision. Furthermore, they suffer from short lifespans and installation difficulties. The latter two are non-contact detection, but due to the requirement for a wide detection range, multiple sensors may need to be installed. However, multiple sensors operating simultaneously present problems such as interference, high cost, and high noise.

[0004] In summary, how to provide a U-shaped arm that can provide collision warning and has good performance has become a technical problem that urgently needs to be solved in this field.

[0005] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is prior art. Summary of the Invention

[0006] The main objective of this application is to provide an infrared detection anti-collision device, a medical rotating U-shaped arm, a control method, and a medium, aiming to solve the technical problem of how to provide a U-shaped arm that provides collision warning and has good performance.

[0007] To achieve the above objectives, this application proposes an infrared detection anti-collision device, which is installed on a medical rotating U-shaped arm; the device includes: a microcontroller unit, a rotary actuator, multiple sets of infrared anti-collision detection boards and diodes, each set of infrared anti-collision detection boards and diodes including one infrared anti-collision detection board and one diode;

[0008] In each set of infrared anti-collision detection boards and diodes, the infrared anti-collision detection board is connected to the positive terminal of the diode;

[0009] The input terminal of the microcontroller is connected to the negative terminals of all diodes, and the output terminal of the microcontroller is connected to the rotary actuator.

[0010] The infrared anti-collision detection board is used to detect whether there is an obstacle approaching the infrared anti-collision detection board by infrared light. If there is an obstacle approaching the infrared anti-collision detection board, the LED outputs a level signal to the microcontroller unit.

[0011] The microcontroller unit is used to receive the level signal from the infrared anti-collision detection board, and when it receives the level signal, it outputs a control command to the rotation execution unit.

[0012] The rotary actuator is used to control the medical rotary U-shaped arm to stop moving when it receives the control command.

[0013] In one embodiment, the infrared anti-collision detection board includes: a collision detection unit, multiple sets of infrared transceiver units and diodes, each set of infrared transceiver units and diodes including an infrared transceiver unit and a diode;

[0014] In each set of infrared transceiver units and diodes, the infrared transceiver unit is connected to the positive terminal of the diode;

[0015] One end of the collision detection unit is connected to the negative terminals of all the diodes, and the other end is connected to the microcontroller unit through a diode;

[0016] The infrared transceiver unit is used to emit and receive infrared light. When there is no obstacle directly in front of the infrared emitting end of the infrared transceiver unit, the infrared receiving end will not receive infrared light. When there is an obstacle directly in front of the infrared emitting end, the infrared receiving end receives infrared light diffusely reflected by the obstacle, and then outputs a voltage signal to the collision detection unit through the diode.

[0017] The collision detection unit is used to determine whether there is an obstacle based on the received voltage signal, and when there is an obstacle, it outputs a level signal to the microcontroller unit.

[0024] When the external power supply is powered on, the infrared light emitting tube emits infrared light. When there is no obstacle in front of the infrared light emitting tube, the infrared light receiving tube is not turned on, and the output of the infrared transceiver unit is low level.

[0025] When there is an obstacle in front of the infrared light emitting tube, the infrared light receiving tube receives the infrared light diffusely reflected by the obstacle and generates a current. The current is converted into a voltage value through the second resistor. The output of the infrared transceiver unit is high level, and the output of the infrared transceiver unit is proportional to the intensity of the infrared light received by the infrared light receiving tube.

[0026] In one embodiment, the collision detection unit includes: an operational amplifier, a comparator, and a switching device;

[0027] One end of the operational amplifier is connected to the output of the infrared transceiver unit, and the other end is connected to one end of the comparator;

[0028] The other end of the comparator is connected to one end of the switching device, and the other end of the switching device is connected to the microcontroller unit via a diode.

[0029] In one embodiment, the operational amplifier is used to proportionally amplify and / or reduce the received voltage value to obtain an intermediate voltage value and output it to the comparator;

[0030] The comparator is used to compare the intermediate voltage value with a preset comparator reference voltage value, and outputs a low level to the switching device when the intermediate voltage value is greater than the comparator reference voltage value.

[0031] When the switching device receives a low level, the output of the operational amplifier is at a high level.

[0032] In addition, to achieve the above objectives, this application also proposes a medical rotating U-arm, which includes the infrared detection anti-collision device described above.

[0033] In one embodiment, the medical rotating U-shaped arm further includes: a rotating U-shaped arm, the rotating U-shaped arm including a base plate, and a side provided on each of the opposite sides of the base plate, the side being perpendicular to the base plate; the cross-section of the arm body formed by the two sides and the base plate is "U" shaped, and a rotating central axis is provided at the center of the base plate, and when the rotating central axis rotates, the base plate rotates together with the rotating central axis;

[0034] The four infrared anti-collision detection plates are vertically arranged on the base plate, and the four infrared anti-collision detection plates are parallel to the four sides of the base plate.

[0035] Furthermore, to achieve the above objectives, this application also proposes a control method, which is applied to the medical rotating U-arm as described above, the method comprising:

[0036] The infrared light from the infrared anti-collision detection plate of the medical rotating U-shaped arm is used to detect whether there is an obstacle approaching the infrared anti-collision detection plate.

[0037] If an obstacle approaches the infrared anti-collision detection board, a level signal is output to the microcontroller unit through the diode;

[0038] When the microcontroller receives the level signal from the infrared anti-collision detection board, it outputs a control command to the rotary actuator.

[0039] When the control command is received through the rotary actuator, the rotary U-shaped arm is controlled to stop rotating.

[0040] In addition, to achieve the above objectives, this application also proposes a storage medium, which is a computer-readable storage medium, on which a computer program is stored, and which, when executed by a processor, implements the steps of the control method described above.

[0041] This application provides an infrared detection anti-collision device, which is installed in a medical rotating U-shaped arm. The infrared anti-collision detection board detects whether there are obstacles in the U-shaped arm, the diode is used for unidirectional transmission of the control circuit, and then the microcontroller unit controls the rotation execution unit according to the detection result, thereby controlling the U-shaped arm to stop running.

[0042] In summary, this application uses infrared light from an infrared anti-collision detection board to detect the presence of obstacles. When an obstacle is detected, the rotation of the U-shaped arm can be stopped in advance to avoid collisions between the obstacle and the U-shaped arm, which could cause personal injury or property damage. Furthermore, it does not require the installation of multiple sensors, thus reducing costs. Therefore, this application provides an infrared detection anti-collision device with good performance that provides collision warning. Attached Figure Description

[0055] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0056] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0057] The main solution of this application embodiment is: the device is installed in a medical rotating U-shaped arm; the device includes: a microcontroller unit, a rotating execution unit, multiple sets of infrared anti-collision detection plates and diodes, each set of infrared anti-collision detection plates and diodes includes one infrared anti-collision detection plate and one diode; in each set of infrared anti-collision detection plates and diodes, the infrared anti-collision detection plate is connected to the positive terminal of the diode; the input terminal of the microcontroller unit is connected to the negative terminals of all diodes, and the output terminal of the microcontroller unit is connected to the rotating execution unit; the infrared anti-collision detection plate is used to detect whether there is an obstacle approaching the infrared anti-collision detection plate by infrared light, and if there is an obstacle approaching the infrared anti-collision detection plate, it outputs a level signal to the microcontroller unit through the diode; the microcontroller unit is used to receive the level signal from the infrared anti-collision detection plate, and when it receives the level signal, it outputs a control command to the rotating execution unit; the rotating execution unit is used to control the medical rotating U-shaped arm to stop moving when it receives the control command.

[0058] In this embodiment, for ease of description, the following description uses a medical rotating U-shaped arm as the execution subject.

[0059] Rotating medical imaging equipment is widely used in the diagnosis of various human diseases. Due to the presence of rotating mechanical components, if the patient suddenly moves during the diagnostic process and the equipment fails to detect this movement and take appropriate action, the rotating mechanical components, such as the U-shaped arm, can easily collide with the patient, causing personal injury. Alternatively, the rotating mechanical components may collide with other objects, causing damage. Therefore, rotating medical diagnostic equipment must have collision detection capabilities. Currently, the mainstream detection methods include capacitive sensing, pressure sensing, mechanical switch sensing, or ultrasonic and laser detection. The first three methods are contact detection, which can only detect when an obstacle comes into contact with the rotating mechanical components. By this time, the human body or the rotating mechanical components may have already been damaged by direct collision. Furthermore, they suffer from short lifespans and installation difficulties. The latter two are non-contact detection, but due to the requirement for a wide detection range, multiple sensors may be needed. However, multiple sensors operating simultaneously present problems such as interference, high cost, and high noise. In summary, how to provide a U-shaped arm with collision warning capabilities and good performance has become a pressing technical problem to be solved in this field.

[0060] To address the aforementioned issues, this application provides an infrared detection anti-collision device. This infrared detection anti-collision device is installed in a medical rotating U-shaped arm. It detects whether there are obstacles in the U-shaped arm through an infrared anti-collision detection board, uses diodes for unidirectional transmission of control circuits, and then controls the rotation execution unit based on the detected results through a microcontroller unit, thereby controlling the U-shaped arm to stop running.

[0061] In summary, this application uses infrared light from an infrared anti-collision detection board to detect the presence of obstacles. When an obstacle is detected, the rotation of the U-shaped arm can be stopped in advance to avoid collisions between the obstacle and the U-shaped arm, which could cause personal injury or property damage. Furthermore, it does not require the installation of multiple sensors, thus reducing costs. Therefore, this application provides an infrared detection anti-collision device with good performance that provides collision warning.

[0062] This application provides a medical rotating U-shaped arm; please refer to... Figure 1 and Figure 2 The medical rotating U-shaped arm includes an infrared detection anti-collision device and a rotating U-shaped arm. The rotating U-shaped arm includes a base plate, and each of the two opposite sides of the base plate has an edge that is perpendicular to the base plate. The cross-section of the arm body formed by the two edges and the base plate is U-shaped. A rotating central axis is set at the center of the base plate. When the rotating central axis rotates, the base plate rotates together with the rotating central axis.

[0063] The four infrared anti-collision detection plates are vertically arranged on the base plate, and the four infrared anti-collision detection plates are parallel to the four sides of the base plate.

[0064] In this embodiment, Figure 1 This is a left-side view of a medical rotating U-shaped arm. Figure 2 This is a frontal view of a medical rotating U-arm. During normal operation, the top of the patient's head (the area being diagnosed) is directly opposite the central axis of rotation of the U-arm within a certain area. The U-arm rotates around this central axis during normal operation, assuming the direction of rotation is as follows... Figure 2 As indicated by the middle arrow. If a person's head moves during the rotation of the U-shaped arm, the person is very likely to collide with the U-shaped arm, causing personal injury.

[0065] The infrared sensing detection principle involves installing four infrared anti-collision detection boards on the top, bottom, left, and right sides of the central axis plane of the rotating U-shaped arm. Several infrared transmitting and receiving pairs are installed at equal intervals on these boards. Figure 1 The direction indicated by the middle arrow is the direction of infrared emission. Figure 2 The area marked by the dashed line represents the region where a human head can move normally without triggering the collision avoidance alarm. When a human head touches... Figure 2 When the infrared beam reaches the boundary of the dashed line area, it will be reflected by the human head onto the infrared receiver tube, triggering an anti-collision alarm. At this time, the device will stop rotating the U-shaped arm to avoid causing secondary personal injury, and at the same time issue an alarm to notify relevant medical personnel to handle the situation.

[0066] This application also provides an infrared detection anti-collision device. Please refer to... Figure 3The device is installed on the aforementioned medical rotating U-shaped arm; the device includes: a microcontroller unit, a rotary actuator, multiple sets of infrared anti-collision detection plates and diodes, each set of infrared anti-collision detection plates and diodes including one infrared anti-collision detection plate and one diode;

[0067] In each set of infrared anti-collision detection boards and diodes, the infrared anti-collision detection board is connected to the positive terminal of the diode;

[0068] The input terminal of the microcontroller is connected to the negative terminals of all diodes, and the output terminal of the microcontroller is connected to the rotary actuator.

[0069] The infrared anti-collision detection board is used to detect whether there is an obstacle approaching the infrared anti-collision detection board by infrared light. If there is an obstacle approaching the infrared anti-collision detection board, the LED outputs a level signal to the microcontroller unit.

[0070] The microcontroller unit is used to receive the level signal from the infrared anti-collision detection board, and when it receives the level signal, it outputs a control command to the rotation execution unit.

[0071] The rotary actuator is used to control the medical rotary U-shaped arm to stop moving when it receives the control command.

[0072] In this embodiment, the infrared anti-collision detection board detects whether a human body is moving within a certain area of ​​the U-shaped arm by reflecting infrared light. The detection range can be set according to the detection sensitivity. Under normal use, the human body will not exceed a certain range within the U-shaped arm area. If an obstacle is detected at the boundary of the range, it indicates that the human body has moved and a collision may be imminent. Then, the microcontroller unit controls the rotation execution unit to stop the medical rotating U-shaped arm from rotating, thus avoiding personal injury or property damage.

[0073] Specifically, an infrared anti-collision detection board is installed on each of the four sides of the rotation axis detection area. The output signal (IR_STA) of each board is isolated and input to the MCU (microcontroller unit) through a diode. When any of the four boards detects an obstacle too close during the rotation of the U-shaped arm, the IR_STA signal on the corresponding board outputs a high level. After receiving this signal status change, the MCU sends a command to the rotation execution unit to stop the rotation of the U-shaped arm, thereby achieving the purpose of protecting personal safety. At the same time, the MCU issues an alarm to notify relevant medical personnel to handle the situation.

[0074] Specifically, in one feasible implementation method, please refer to Figure 4The infrared anti-collision detection board includes: a collision detection unit (unit B), multiple sets of infrared transceiver units (unit A) and diodes, each set of infrared transceiver units and diodes including an infrared transceiver unit and a diode;

[0075] In each set of infrared transceiver units and diodes, the infrared transceiver unit is connected to the positive terminal of the diode;

[0076] One end of the collision detection unit is connected to the negative terminals of all the diodes, and the other end is connected to the microcontroller unit through a diode;

[0077] The infrared transceiver unit is used to emit and receive infrared light. When there is no obstacle directly in front of the infrared emitting end of the infrared transceiver unit, the infrared receiving end will not receive infrared light. When there is an obstacle directly in front of the infrared emitting end, the infrared receiving end receives infrared light diffusely reflected by the obstacle, and then outputs a voltage signal to the collision detection unit through the diode.

[0078] The collision detection unit is used to determine whether there is an obstacle based on the received voltage signal, and when there is an obstacle, it outputs a level signal to the microcontroller unit.

[0079] In this embodiment, the infrared anti-collision detection board includes multiple sets of infrared transceiver units and diodes, and a collision detection unit. The infrared transceiver units are used to emit and receive infrared light. When there is an obstacle, the diffuse reflection of the obstacle surface will allow the infrared transceiver units, which would not normally receive infrared light, to receive infrared light, thereby generating current and outputting voltage to the collision detection unit. After detecting the voltage, the collision detection unit determines that a collision is about to occur or has already occurred, and further outputs a level signal to the microcontroller unit.

[0080] Specifically, in one feasible implementation method, please refer to Figure 5 The infrared transceiver unit includes a first resistor, a second resistor, an infrared light emitting tube, and an infrared light receiving tube;

[0081] The first end of the first resistor is connected to an external power supply, and the second end is connected to the first end of the infrared light emitting tube.

[0082] The second end of the infrared emitting diode is grounded;

[0083] The first end of the infrared light receiving tube is connected to the output end of the infrared transceiver unit, and the second end of the infrared light receiving tube is connected to an external power supply.

[0084] The first end of the second resistor is connected to the output terminal of the infrared transceiver unit, and the second end of the second resistor is grounded.

[0085] Furthermore, the external power supply powers the infrared transceiver unit, the first resistor is used to limit the current of the infrared light emitting tube, and the second resistor is used to convert the current value of the infrared light receiving tube into a voltage value.

[0086] When the external power supply is powered on, the infrared light emitting tube emits infrared light. When there is no obstacle in front of the infrared light emitting tube, the infrared light receiving tube is not turned on, and the output of the infrared transceiver unit is low level.

[0087] When there is an obstacle in front of the infrared light emitting tube, the infrared light receiving tube receives the infrared light diffusely reflected by the obstacle and generates a current. The current is converted into a voltage value through the second resistor. The output of the infrared transceiver unit is high level, and the output of the infrared transceiver unit is proportional to the intensity of the infrared light received by the infrared light receiving tube.

[0088] In this embodiment, VCC powers the infrared transceiver unit circuit, D1 is an infrared light emitting diode, IRD1 is an infrared light receiving diode, and resistor R1 limits the current to the infrared light emitting diode D1 to prevent it from burning out due to excessive current. Resistor R2 converts the current value of IRD1 into a voltage value, and sig1 is the output voltage signal of the infrared transceiver unit circuit. D1 and IRD1 form an infrared transmitting and receiving pair, and when soldered, they face the same direction and are spaced approximately 3mm apart.

[0089] When VCC is powered on, D1 starts emitting infrared light. When there are no obstacles directly in front of D1, IRD1 is in a non-conducting state, and sig1 outputs zero voltage. When an obstacle appears directly in front of D1, the infrared light is diffusely reflected into IRD1. At this time, IRD1 generates different current values ​​depending on the intensity of the received infrared light. This current is converted into a voltage value through resistor R2. The stronger the received infrared light, the higher the output voltage value of sig1, indicating that the obstacle is closer to the infrared transmitter-receiver pair; the weaker the received infrared light, the lower the output voltage value of sig1, indicating that the obstacle is farther away from the infrared transmitter-receiver pair.

[0090] Because the infrared light emitting tube has a very small emission angle, the detection range is small. In practical applications, multiple infrared transceiver unit circuits need to be evenly arranged at equal intervals on the infrared anti-collision detection board according to the detection range and the size of the object to be detected, in order to improve the detection range and resolution.

[0091] Specifically, in one feasible implementation method, please refer to Figure 6 The collision detection unit includes: an operational amplifier, a comparator, and a switching device;

[0092] One end of the operational amplifier is connected to the output of the infrared transceiver unit, and the other end is connected to one end of the comparator;

[0093] The other end of the comparator is connected to one end of the switching device, and the other end of the switching device is connected to the microcontroller unit via a diode.

[0094] Furthermore, the operational amplifier is used to proportionally amplify and / or reduce the received voltage value to obtain an intermediate voltage value and output it to the comparator;

[0095] The comparator is used to compare the intermediate voltage value with a preset comparator reference voltage value, and outputs a low level to the switching device when the intermediate voltage value is greater than the comparator reference voltage value.

[0096] When the switching device receives a low level, the output of the operational amplifier is at a high level.

[0097] In this embodiment, the operational amplifier can proportionally amplify and / or reduce the received voltage value to a processable voltage value, and then the comparator determines whether it is necessary to pause the rotation of the U-shaped arm.

[0098] Specifically, the operational amplifier includes: the third resistor, the fourth resistor, the fifth resistor, the sixth resistor, the eighth resistor, and the operational amplifier itself; the comparator includes: the seventh resistor, the ninth resistor, the tenth resistor, and the comparator itself; the switching devices include: the eleventh resistor, the twelfth resistor, the first capacitor, and the NPN transistor; the connection relationships of each component are as follows: Figure 7 As shown, U1 is an operational amplifier, U2 is a comparator, VDD supplies power to U1 / U2, R4 / R5 amplifies the input voltage proportionally, R6 / R8 reduces the input voltage proportionally, VREF is the comparator reference voltage value, Q1 converts the comparator output voltage value into the 3.3V voltage value required by the MCU, and IR_STA is the output voltage signal of the unit B circuit, which is output to the MCU.

[0099] As an obstacle gets closer to the infrared transmitter-receiver pair, the output signal sig1 voltage of unit A circuit increases. The highest output signal voltage of unit A circuit is input to unit B circuit via a diode. Unit B circuit receives the output voltage signal from unit A circuit and amplifies / reduces this signal (IROUT) proportionally through operational amplifier U1 to obtain a suitable voltage value. This value is then compared with the VREF value through comparator U2. When the sig1 signal voltage, after processing by the operational amplifier, rises to a level greater than VREF, U2.7 outputs a low level, Q1 disconnects, and IR_STA changes from low (0V) to high (3.3V). This signal state change is transmitted to the MCU, which uses this information to determine whether an obstacle exists in front of the infrared transmitter-receiver pair and whether to trigger the anti-collision alarm. The trigger distance can be adjusted by adjusting the resistance values ​​of R4 to R6.

[0100] Based on the above hardware structure, this application provides a control method, referring to... Figure 8 , Figure 8 This is a flowchart illustrating an embodiment of the control method for the display device of this application.

[0101] In this embodiment, the power-saving method of the display device includes steps S10 to S40:

[0102] Step S10: Detect whether an obstacle is approaching the infrared anti-collision detection plate of the medical rotating U-shaped arm using infrared light.

[0103] In this embodiment, the infrared collision avoidance detection system on the medical rotating U-arm begins operation. This system is equipped with one or more infrared collision avoidance detection plates, each containing an infrared emitter and receiver. The infrared emitter emits infrared beams, which are captured by the corresponding receiver when there are no obstructions. Once an object enters the beam path, part of the light is blocked, causing a change in the intensity of the infrared light received by the receiver.

[0104] Step S20: If an obstacle approaches the infrared anti-collision detection board, a level signal is output to the microcontroller unit through the diode;

[0105] In this embodiment, when the infrared receiver of the detection board detects a significant change in infrared light intensity, it determines that an obstacle is approaching. At this time, the circuit within the detection system is triggered, outputting an electrical level signal. This signal serves as a warning signal and is directly sent to the microcontroller unit (MCU). The MCU, acting as the "brain" of the entire system, is responsible for processing various input signals and making corresponding decisions.

[0106] Step S30: When the microcontroller receives the level signal from the infrared anti-collision detection board, it outputs a control command to the rotation execution unit.

[0107] In this embodiment, after receiving the level signal from the diode, the microcontroller unit immediately recognizes it as an obstacle alarm from the infrared anti-collision system. Based on the preset program logic, the MCU responds quickly and issues a specific control command to the rotary actuator. This command may be a digital signal or a pulse signal, depending on the control interface and protocol of the rotary actuator; its purpose is to instruct the actuator to take necessary safety measures.

[0108] Step S40: When the control command is received through the rotation execution unit, the rotation of the U-shaped arm is stopped.

[0109] In this embodiment, upon receiving the control command from the microcontroller unit, the rotary actuator immediately performs the corresponding action—stopping the rotation of the U-shaped arm. This step ensures that the U-shaped arm can brake in time when an obstacle is detected, avoiding collision with the obstacle and protecting the safety of the patient, medical staff, and the equipment itself.

[0110] Compared with the prior art, the beneficial effects of the control method provided in this application are the same as those of the infrared detection anti-collision device provided in the above embodiments, and other technical features in the control method are the same as those disclosed in the above embodiments, and will not be repeated here.
