Description

Background technique

With the development of technology, there are currently a variety of operating beds on the market that are used to assist doctors in medical behaviors, including but not limited to electric operating beds. Taking the electric operating table as an example, the inclination angle of the bed (i.e., the operating table body) can be quickly adjusted through the control terminal, thereby conveniently adjusting the patient's position during the operation and facilitating the execution of the operation.

These operating tables have complex structures, and their components may malfunction due to wear or aging during long-term use. The current common method of detecting faults is to drive the entire surgical bed to perform specific actions, and analyze the faulty components based on abnormalities that occur during the execution process.

However, when the operating table performs a specific action, multiple components are often involved at the same time. Even if there is an abnormality in the execution of a certain action, this method is difficult to analyze which component is specifically caused by the failure of the abnormality. Therefore, this detection method is difficult to malfunction. The parts are positioned quickly and accurately, and the detection efficiency is low.

Detailed ways

This application provides an imaging method and an imaging system for improving the comprehensiveness of image display.

The terms "first", "second", "third", "fourth", etc. (if present) in the description and claims of this application and the above-mentioned drawings are used to distinguish similar objects without necessarily using Used to describe a specific order or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances so that the embodiments described herein can be practiced in sequences other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, e.g., a process, method, system, product, or apparatus that encompasses a series of steps or units and need not be limited to those explicitly listed. Those steps or elements may instead include other steps or elements not expressly listed or inherent to the process, method, product or apparatus.

This application relates to a fault detection method for electric operating beds and other medical equipment. In order to facilitate understanding of the technical solution of this application, first, the structure and operation of the electric operating bed are briefly described with reference to the structural schematic diagram of the electric operating bed shown in Figure 1. principle.

The electric operating table (hereinafter referred to as the operating table) usually consists of a control system, a mechanical system, etc. The mechanical system includes an oil pump 105, a solenoid valve 106, a hydraulic cylinder 107 and a movable component 108; the control system includes an oil pump drive 102, a pressure Detection circuit 103, solenoid valve driver 104 and controller 101.

When the user controls the operating table to perform a specified action through the control terminal, the controller controls the oil pump to start working through the oil pump drive, and at the same time controls the solenoid valve to open a certain oil circuit of the solenoid valve through the solenoid valve drive. As a result, the oil pump pumps oil through the opened oil circuit. The oil cylinder moves the movable components connected to the oil cylinder to complete the specified action.

The movable components may include any one or more of the operating table table, head board (head support board), leg board (leg support board), back board (back support board) and lumbar bridge (lumbar support board) .

Different movable components have different actions when driven. Taking the above movable components as an example, when the movable component is the tabletop of an operating table, the movement of the movable component can be the head tilt, foot tilt, or tilt of the tabletop. Any of left tilt, right tilt, move up, move down, left move and right move.

When the movable component is the head support plate of the operating table, the movement of the movable component may be the turning of the head support plate.

When the movable component is the back support plate of the operating table, the movement of the movable component may be the bending of the back support plate.

When the movable component is a lumbar support panel of the operating table, the movement of the movable component may be an upward or downward movement of the lumbar support panel.

When the movable component is the leg support board of the operating table, the movement of the movable component may be the turning of the leg support board.

When the movable component moves, the angle sensor and stroke sensor provided on the movable component can detect the status of the movable component and feed it back to the controller. Specifically, it can detect the angle and stroke of the movable component.

According to the above working principle, it can be understood that a failure of the oil pump or solenoid valve, such as the oil pump having no power output, the solenoid valve not completing the oil circuit switching, etc., will cause the operating bed to be unable to respond to the instructions of the control terminal and perform specified actions.

Embodiment 1

In order to detect a fault of the operating bed, this embodiment provides a fault detection method. The fault detection method of this embodiment is applied to the operating bed. The operating bed includes a support part for supporting the patient's body, a plurality of driving components, and a user input operation. At least one input component for parameters, at least one output component for outputting information, and a controller for controlling operation of the operating table. The support portion includes at least one movable component.

The plurality of driving assemblies at least include a first driving assembly and a second driving assembly, and the first driving assembly and the second driving assembly jointly perform work for driving movement of one of the at least one movable assembly.

The plurality of driving assemblies mentioned above may include an oil pump driving assembly and a plurality of solenoid valve driving assemblies. The first driving assembly may be an oil pump driving assembly or any one of the plurality of solenoid valve driving assemblies.

The second driving component is each driving component in the plurality of driving components except the first driving component.

The oil pump drive component may include an oil tank, an oil pump feedback circuit, an oil pump as shown in Figure 1, and an oil pump drive (also known as an oil pump drive circuit).

The solenoid valve drive assembly may include a solenoid valve feedback circuit, as well as the solenoid valve and solenoid valve drive (also known as the solenoid valve drive circuit) shown in Figure 1.

Please refer to Figure 2, which is a flow chart of a fault detection method provided in this embodiment. The method may include the following steps.

S201: When fault detection is performed on the first driving component, the first driving component is controlled to perform work, and the second driving component is controlled to stop working.

Step S201 can be specifically executed by the controller of the operating bed. That is to say, when performing fault detection on the first driving component, the controller of the operating bed can control the operation of the first driving component and simultaneously control the first driving component in the operating bed. Every drive component except

Combined with the previous description, in S201, if the first driving component is an oil pump driving component, the controller controls the oil pump driving component to work, and at the same time controls each solenoid valve component to stop working, so that the oil circuit of each solenoid valve remains closed. . When the oil pump drive assembly is working, the oil pump pumps oil into the oil circuit. However, since the oil circuit corresponding to each solenoid valve remains closed, the oil will not flow into the oil cylinder connected to the movable component, and the movable component will not move.

If the first driving assembly is any one of the target solenoid valve driving assemblies among the plurality of solenoid valve driving assemblies, the controller controls the oil pump driving assembly and each solenoid valve assembly except the target solenoid valve assembly to stop working. At this time, the oil circuit corresponding to the target solenoid valve assembly is open, but the oil pump driving assembly does not work, and the oil body will not be pumped into the oil cylinder through the opened oil circuit, so the movable component connected to the oil cylinder does not move.

S202: Obtain the detection result corresponding to the first driving component according to the electrical signal when the first driving component is working.

The detection result corresponding to the first driving component includes whether there is a fault in the first driving component.

The electrical signal when the first driving component is working can be obtained through a feedback circuit pre-set in the first driving component. Specifically, when the first driving component is an oil pump driving component, the electrical signal when the oil pump driving component is working can be obtained through the oil pump feedback circuit. When the first driving component has a target solenoid valve driving component, the electrical signal when the target solenoid valve driving component is working, It can be obtained through the solenoid valve feedback circuit.

The specific execution method of step S202 may be:

Obtain the electrical signal when the first driving component is working.

Determine whether the electrical signal of the first driving component is within a preset signal range corresponding to the first driving component.

The preset signal ranges corresponding to different drive components can be different. The preset signal ranges corresponding to different driving components can be recorded in a storage unit connected to the controller. When performing step S202, the controller reads the corresponding preset signals from the storage unit based on the first driving component currently performing fault detection. scope.

The electrical signal when the first driving component is working can be the current when the first driving component is working, and the preset signal range can be the preset current range.

If it is determined that the electrical signal of the first driving component is not within the preset signal range corresponding to the first driving component, it is determined that the corresponding detection result of the first driving component is a fault.

If it is determined that the electrical signal of the first driving component is within the preset signal range corresponding to the first driving component, it is determined that the corresponding detection result of the first driving component is that there is no fault.

S203. Output the detection result corresponding to the first driving component in at least one output component.

The detection result corresponding to the first driving component can be directly output regardless of whether the first driving component has a fault; it can also be output only when the first driving component has a fault, and not output when the first driving component does not have a fault.

The output components of the operating table can include indicator lights, speakers, display screens on the operating table control panel, etc. Correspondingly, the output methods of detection results include voice mode, indicator light mode, alarm mode, text mode, and image identification mode. One or more items.

Here are some examples of output methods of detection results for reference:

First, multiple indicator lights corresponding to multiple drive components are provided on the operating bed. When the detection result of the first drive component is that there is a fault, the indicator light corresponding to the first drive component is controlled to emit a specific color of light (such as red light). ) to indicate a fault in the first drive component.

Second, the storage unit of the operating bed pre-stores warning texts corresponding to different driving components. When the detection result of the first driving component is that there is a fault, the corresponding warning text is read and the warning text is output in the form of voice. For example, if the first driving component is an oil pump driving component, and the detection result is that the oil pump driving component is faulty, a voice message of "There is a fault in the oil pump" is output.

Third, icons corresponding to different driving components are set in advance. When the detection result is that the first driving component is faulty, the icon corresponding to the first driving component is displayed on the display screen of the operating bed, and the icon is controlled to flash, or the icon is Displayed in a specific color, such as red.

Optionally, the detection results corresponding to the first driving component can also be output through a control terminal that is communicatively connected to the operating bed. The control terminal may be a remote control, a wire controller of the operating table, a control panel of the operating table, a user terminal, a central station, a monitor or other controllers of the operating table.

Optionally, the detection results corresponding to the first driving component can also be output through a third-party terminal device that is communicatively connected to the operating bed. For example, the operating bed can be connected to a computer through a local area network, and the test results of the first drive component are output through the computer; the operating bed can be connected to a medical staff's mobile terminal (such as a smartphone) through Bluetooth or LAN, and the test results of the first drive component are Output via mobile terminal.

By controlling the terminal or a third-party terminal device to output the detection results, any one or more of the multiple methods of outputting the detection results for the aforementioned operating bed can be used, which will not be described again.

It should be noted that the fault detection method provided in this embodiment can not only be used to detect the first driving component, but can also be used to sequentially detect other driving components of the operating table after detecting the first driving component.

That is to say, in the embodiment shown in Figure 2, after executing S202 to obtain the detection result of the first driving component, any second driving component can also be detected, or multiple second driving components can be detected one by one, thereby obtaining the detected result. The detection result of the second driving component is detected, and the detection result of the second driving component includes whether there is a fault in the second driving component.

Each time a second driving component is detected, the detection method is the same as the detection method for detecting the first driving component shown in FIG. 2 . That is to say, every time a fault detection is performed on a second driving component, the controller of the operating bed controls the work of the second driving component currently undergoing fault detection, and simultaneously controls every other driving component (including the first driving component). component) stops working, thereby acquiring the electrical signal when the detected second driving component is working, and determining the detection result according to whether the electrical signal is within the preset signal range corresponding to the detected second driving component.

For the above specific implementation process, please refer to steps S201 and S202, which will not be described again.

When this embodiment is used to detect multiple driving components including a first driving component and at least one second driving component, the output detection result in step S203 may be after detecting each driving component that needs to be detected, The detection results of these drive components are output together; or, after each drive component is detected, the detection results of one drive component are output. The detection results are output as described above.

The execution process of this embodiment will be described below with reference to specific driving components.

When the first driving component is an oil pump driving component and the second driving component is a solenoid valve driving component, the execution process is as follows.

Please refer to FIG. 3 , which is a schematic structural diagram of an oil pump driving assembly provided in this embodiment. The oil pump driving assembly includes an oil pump driving circuit 102, an oil pump 105, an oil pump feedback circuit 301 and an oil tank 302. The oil pump driving assembly and the solenoid valve driving assembly are connected through an oil pipe 303, and a pressure sensor 304 is provided on the oil pipe 303.

As shown in Figure 3, when the oil pump driving component is working and the solenoid valve driving component is not working, the oil pump is turned on and the solenoid valve remains closed. At this time, the oil pump outputs power to pump the oil in the tank into the oil circuit. Due to the closing of the solenoid valve, the The oil pump is in overflow drive. In the overflow drive state, the output power of the oil pump drive circuit will be maintained within a fixed power range. You can determine whether there is a fault in the oil pump drive component by detecting the drive current I (that is, the output current of the oil pump drive circuit). If the drive current If it is close to 0, or even lower than 0, it can be determined that there is a fault in the oil pump drive component.

Based on the above principles, controlling the first driving component to perform work and controlling the second driving component to stop working in step S201 may include:

The oil pump and the oil tank are controlled to perform work by controlling the oil pump driving circuit, and the plurality of solenoid valve driving assemblies are controlled to stop working.

Obtaining the detection result corresponding to the first driving component according to the electrical signal when the first driving component is working in step S202 may include:

Obtain the electrical signal output by the oil pump feedback circuit, and determine whether the electrical signal output by the oil pump feedback circuit is within the preset signal range corresponding to the oil pump driving component; if not, it is determined that the oil pump driving component is faulty; if so, it is determined that the oil pump driving component is faulty There is no fault.

The electrical signal output by the above-mentioned oil pump feedback circuit may specifically be a driving current. The lower limit of the preset signal range of the oil pump driving component can be a positive number slightly greater than 0, and the upper limit can be the maximum current value that the oil pump driving circuit can output. The specific numerical values of the upper limit and the lower limit here can be determined according to the model and performance of the oil pump drive circuit configured on the actual operating bed, and are not limited in this embodiment. If the driving current is less than the lower limit, or greater than the upper limit, it is determined that there is a fault in the oil pump driving component.

Optionally, when the first driving component is an oil pump driving component, it is also possible to detect whether there is a fault in the oil pump driving component based on the driving current of the oil pump driving component and further combined with the oil pressure in the oil circuit.

As shown in Figure 3, the oil pump driving assembly may further include a pressure sensor, and the pressure sensor is disposed on the oil pipe connecting the oil pump driving assembly and the solenoid valve driving assembly. The pressure sensor is used to detect the oil pressure in this section of oil pipe, and feedback the detected oil pressure to the controller through the pressure detection circuit.

Therefore, in step S202, the detection result of the oil pump driving assembly can be determined by combining the driving current and the oil body pressure.

That is to say, in S202, the detection result corresponding to the first driving component is obtained based on the electrical signal when the first driving component is working, which also includes:

Obtain the oil pressure detected by the pressure sensor;

If the electrical signal output by the oil pump feedback circuit is within the preset signal range corresponding to the oil pump driving assembly, and if the oil body pressure is less than the preset pressure, it is determined that the oil pump driving assembly is faulty.

Among them, if the electrical signal output by the oil pump feedback circuit is within the preset signal range corresponding to the oil pump drive component, it means that the oil pump drive circuit can work normally and output current to the oil pump, and the oil body pressure is less than the preset pressure, which means that the oil pump is driven by the oil pump. If the current output by the circuit does not pump the oil body into the oil circuit normally, that is, the oil pump may be faulty. Therefore, in this case, it can be determined that the oil pump driving component is faulty.

The first driving component is the target solenoid valve driving component, the second driving component is the oil pump driving component, and other solenoid valve driving components except the target solenoid valve driving component. At this time, the execution process of this embodiment is as follows.

Please refer to FIG. 4 , which is a schematic structural diagram of a solenoid valve driving assembly provided by an embodiment of the present application.

As shown in Figure 4, multiple solenoid valve drive components include a solenoid valve drive circuit 104, a solenoid valve feedback circuit 400 and multiple solenoid valves 106. The multiple solenoid valves 106 can be divided into different types according to the different movable components they drive. Leg plate valve 461, back plate valve 462, lift valve 463, etc.

Each solenoid valve is electrically connected to the solenoid valve drive circuit; each solenoid valve is electrically connected to the solenoid valve feedback circuit. In Figure 4, at least one solenoid valve, the solenoid valve driving circuit, the solenoid valve feedback circuit, and the switch connected to the solenoid valve can be regarded as a solenoid valve driving component.

For example, in Figure 4, the leg plate valve drive assembly includes the leg plate valve, switch S3, solenoid valve drive circuit and solenoid valve feedback circuit; the back plate valve drive assembly includes the back plate valve, switch S3, solenoid valve drive circuit and solenoid valve. Feedback circuit; lift valve drive assembly, including lift valve, switch S3, solenoid valve drive circuit and solenoid valve feedback circuit.

Wherein, multiple solenoid valve driving components can share the solenoid valve driving circuit and the solenoid valve feedback circuit.

When it is necessary to control the operation of the target solenoid valve driving assembly, the controller turns on the switch of the target solenoid valve driving assembly so that the driving current passes through the solenoid valve of the target solenoid valve driving assembly. For example, when the target solenoid valve driving component is the leg plate valve driving component, the controller can turn on switch S3 to control the operation of the leg plate valve driving component, and at the same time control other switches to open, thereby controlling other components except the leg plate valve driving component. The solenoid valve driver assembly is not working.

For each solenoid valve, when the solenoid valve operates normally, the driving current flowing through the solenoid valve will generally remain within a certain fixed current range. Therefore, in this embodiment, the fixed current range can be determined as the preset signal range corresponding to the solenoid valve driving component.

After controlling the operation of the target solenoid valve drive component, the controller can obtain the drive current I of the solenoid valve of the target solenoid valve drive component through the solenoid valve feedback circuit, and determine whether the drive current is within the preset signal range corresponding to the target solenoid valve drive component. Within, if it is, it is determined that there is no fault in the target solenoid valve driving component; if not, it is determined that there is a fault in the target solenoid valve driving component.

It should be noted that each solenoid valve driving component is used to drive a type of movement of a movable component of the operating table. The type of movement of the movable component can be driven by one or more solenoid valves, so the target solenoid valve driving component , may include one or more solenoid valves. When performing fault detection on the target solenoid valve drive component, in the case of sharing the solenoid valve drive circuit, if among the multiple solenoid valves included in the target solenoid valve drive component, the multiple solenoid valves are all connected (that is, the switches corresponding to the solenoid valves (closed), obtain the driving current of the common driving circuit. If the driving current is not within the preset signal range, it can be determined that there is a fault in the multiple solenoid valves, and then it is determined that the target solenoid valve driving component is faulty.

To sum up, controlling the first driving component to perform work and controlling the second driving component to stop working in step S201 includes:

The solenoid valve driving circuit is controlled to cause at least one solenoid valve to work, other solenoid valve components are controlled to stop working, and the oil pump driving component is controlled to stop working.

In step S202, based on the electrical signal when the first driving component is working, the detection result corresponding to the first driving component is obtained, including:

Obtain the electrical signal output by the solenoid valve feedback circuit, and determine whether the electrical signal output by the solenoid valve feedback circuit is within a preset signal range corresponding to the target solenoid valve drive component; if not, it is determined that the target solenoid valve drive component is faulty; if so , then it is determined that there is no fault in the target solenoid valve driving component.

Optionally, in the embodiment shown in FIG. 2 , before step S201 , it may also include obtaining a detection instruction for performing fault detection on the first driving component.

Or it may also include obtaining a detection instruction to perform fault detection in the fault detection mode.

The fault detection mode is a preset detection mode of the operating table. In this embodiment, the fault detection mode is at least used to instruct fault detection on multiple driving components of the operating table.

It can be understood that the driving components indicated by the fault detection mode to perform fault detection include at least the first driving component.

In other words, the embodiment shown in Figure 2 can be executed after obtaining the detection instruction to perform fault detection on the first driving component, or after obtaining the detection instruction to perform fault detection in the fault detection mode.

The beneficial effect of this embodiment is that when detecting the first driving component, the second driving component is controlled to stop working. Therefore, if an abnormality is found during the detection process, it can be directly determined that the first driving component has failed, achieving the effect of quickly locating the fault location. , improving the efficiency of fault detection.

Moreover, since the first driving component works but the second driving component does not work, the movable component of the operating table will not move, thus avoiding damage caused by the movable component moving in the presence of a fault.

The detection instructions for performing fault detection on the first drive component can be obtained in any of the following ways:

After the operating table is turned on, a detection instruction for performing fault detection on the first driving component is obtained.

When the operating table is powered on and the system time of the operating table reaches a preset detection time point, a detection instruction is obtained to perform fault detection on the first driving component; the preset detection time point can be set according to specific application scenarios. , for example, set to 1 hour after the operating table is turned on.

In the above two methods, the detection instructions for performing fault detection on the first driving component can be recorded in the storage unit of the operating bed in advance. When the above conditions are met (power on, or a certain period of time after power on), the operating bed obtains the instruction from the storage unit. A detection instruction for fault detection is executed on the first driving component, and then the method of this embodiment is executed based on the instruction.

A detection instruction for performing fault detection on the first driving component is received through the input component, or a detection instruction for performing fault detection on the first driving component is received from the control terminal; the input component can be a keyboard or a touch panel on the operating bed, that is, medical care The personnel can trigger the operating bed to perform fault detection on the first driving component by operating the keyboard or touch panel of the operating bed, or operating the control terminal of the operating bed.

The detection instructions for performing fault detection in fault detection mode can be obtained in any of the following ways:

After the operating table is turned on, the detection instructions for performing fault detection in the fault detection mode are obtained.

When the operating table is powered on and the system time of the operating table reaches the preset detection time point, a detection instruction to perform fault detection in the fault detection mode is obtained; the preset detection time point can be set according to the specific application scenario , for example, set to 1 hour after the operating table is turned on.

In the above two methods, the detection instructions for performing fault detection in the fault detection mode can be pre-recorded in the storage unit of the operating bed. When the above conditions are met (power on, or a certain period of time after power on), the operating bed obtains from the storage unit A detection instruction for fault detection is executed in the fault detection mode, and then the method of this embodiment is executed based on the instruction.

Receive the detection instruction to perform fault detection in the fault detection mode through the input component, or receive the detection instruction to perform fault detection in the fault detection mode sent by the control terminal; the input component can be a keyboard or touch panel on the operating bed, that is, medical care Personnel can trigger the operating table to enter the fault detection mode by operating the keyboard or touch panel of the operating table, or operating the control terminal of the operating table, thereby performing fault detection in the fault detection mode.

It can be understood that, in addition to the aforementioned components, the operating bed may also include a storage unit and at least one sensor. The at least one sensor may include at least one of an angle sensor, a displacement sensor and a position sensor.

The storage unit is usually used to store important data. For example, medical staff can set at least one composite posture movement in the operating bed. Each composite posture movement corresponds to at least one movable component and the corresponding position value and stroke limit of the movable component. Bit values, these data can be recorded in memory cells.

In some optional embodiments, the fault detection mode is also used to indicate fault detection of at least one movable component. Therefore, after executing the detection instruction of fault detection in the fault detection mode, the controller may also perform fault detection on at least one movable component.

The process of performing fault detection on moveable components may include:

In the case of performing fault detection on the target movable component, detecting the current movement condition of the target movable component, where the target movable component is any one of the at least one movable component;

Obtain whether there is an input driving instruction to the target movable component before the current motion situation and if so, obtain the input driving instruction;

Compare the drive command with the current motion situation to determine whether the detection result corresponding to the target movable component is normal motion or abnormal motion;

Abnormal motion includes movement of the target movable component without a drive command, movement in the opposite direction with a drive command, movement with a different speed with a drive command, movement with an incorrect moving distance with a drive command, and wrong tilt angle with a drive command. At least one of motion and motion with wrong bending angle under drive command.

It can be understood that when the controller performs fault detection on at least one movable component, it can sequentially determine each movable component as a target movable component, and then detect the target movable component according to the above detection method, and finally obtain at least one movable component. Test results for each component.

The current movement status of the target movable component may specifically include whether the target movable component is currently in a moving state or a static state, and the range of motion when it is in the moving state.

Specifically, the sensor of the operating bed can detect the position data of the movable component at a certain time interval and report the position data to the controller. The controller of the operating bed can detect the position data of the target movable component according to the position data received within the preset time period. The position data determines the movement of the target movable component.

Among them, the position data can include the height, horizontal displacement, folding angle, tilt angle, etc. of the movable component.

Taking the preset time period as 60 seconds (s) and the time interval as 30s as an example, the controller can compare the location data reported by the sensor within these 60s. If there is a difference in the location data received within these 60s, it can be determined The target movable component is in a moving state. If there is no difference in the position data received within 60 seconds, it can be determined that the target movable component is in a stationary state.

After determining that the target movable component is in motion, the controller can determine the calculated difference between the two adjacent position data received within 60 seconds as the movement amplitude of the target movable component. For example, the controller can calculate the difference between the position data received 60 seconds ago and the position data received 30 seconds ago as the motion amplitude, or calculate the difference between the position data received 30 seconds ago and the currently received position data as the motion amplitude. .

Optionally, when there are multiple differences, the controller can use the largest difference as the movement amplitude of the target movable component, or use the difference in position data obtained before and after the most recent time interval as the movement amplitude of the target movable component. The range of motion is not limited in this embodiment.

Taking the countertop as an example, the controller obtains the height data of the countertop in the last 60 seconds through the sensor. Through comparison, it is found that the height data of the countertop in the last 60 seconds is inconsistent, so the controller determines that the countertop is in motion. Then, the controller calculates the height of the countertop 30 seconds ago. The difference between the data and the current table height data is used as the movement amplitude of the table.

When the target movable component is a leg support board or a head support board, the controller can calculate the difference between the angle data of the target movable component 30 seconds ago and the current angle data as the motion range. The specific process is similar to that of the table. Repeat.

Whether there is an input drive instruction to the target movable component can be determined by detecting the input status of the input component.

If the controller detects that the input state of the input component is an input state and the operation instruction obtained through the input component is a valid operation instruction, it generates a motion drive instruction based on the valid operation instruction and sends the motion drive instruction to The driving component corresponding to the movable component.

If the controller detects that the input state of the input component is a no-input state or an invalid input state, that is, the operation instruction obtained by the input component is determined to be an invalid operation instruction, it will not send a motion drive instruction to the driving component corresponding to the movable component.

Therefore, the controller can detect whether the input component obtains a valid operation instruction for the target movable component input by the user before the current movement situation. If a valid operation instruction for the target movable component is obtained, it is determined that the target movable component has input. The drive command is obtained, and the drive command generated based on the valid operation command is obtained. If the valid operation command is not obtained, it is determined that the target is movable and no drive command is input.

That is to say, when it is determined that there is at least one of the following conditions according to the movement conditions and driving instructions of the target movable component, it is determined that the detection result of the target movable component is abnormal motion. If it is not determined that there is no each of the following conditions, it is determined that the target The detection result of the movable component is normal movement:

Case 1: Movement without driving instructions, that is, no driving instructions are input to the target movable component, but the movement of the target movable component is in a moving state.

Case 2: Movement in opposite directions with a drive command, that is, the target movable component has an input drive command, and the movement of the target movable component is in a moving state, but the direction of movement is different from the direction indicated by the drive command. The direction of movement is determined based on the amplitude of movement. For example, if the height data 30 seconds ago is greater than the current height data, the movement direction is determined to be downward. If the left tilt angle 30 seconds ago is smaller than the current left tilt angle, the movement direction is determined to be tilt to the left.

Case 3: Different speed movement under drive command, that is, the target movable component has an input drive command and the target movable component is in motion, but the movement speed is an abnormal value. The movement speed can be determined based on the difference in position data before and after a time interval. For example, if the difference between the height data 30s ago and the current height data is 4cm, then the movement speed is determined to be 4cm every 30 seconds. The difference between the left tilt angle 30s ago and the current left tilt angle is 5 degrees. After determining the movement The speed is 5 degrees every 30 seconds.

The operating table can be preset with a normal movement speed range, or the corresponding normal movement speed range can be determined based on the movement amplitude indicated by the drive instruction. If the movement speed of the target movable component exceeds the normal movement speed range, the movement speed is determined to be abnormal. value.

Case 4: The target movable component has an input drive instruction, but the final movement amplitude of the target movable component is wrong, that is, the final movement amplitude of the target movable component is inconsistent with the movement amplitude indicated by the drive instruction.

The final range of motion of different target movable components is different. For example, the final range of motion of the tabletop can be the moving distance or the tilt angle. The final range of motion of the leg support plate and the head support plate can be the bending angle. Therefore, case 4 can be specifically divided into motion with an incorrect moving distance under the driving command, motion with an incorrect tilt angle under the driving command, and motion with an incorrect bending angle under the driving command.

The range of motion indicated by the drive command can be determined based on the effective operation command input by the user in the input component. For example, if the user inputs a valid operation command to raise the table by 5cm in the input component, then the range of motion indicated by the generated drive command is to raise the table by 5cm. .

The final movement amplitude of the target movable component may be the difference between the position data before the target movable component enters the movement state and the position data at the end of the movement state. Taking the target movable component as a tabletop as an example, before entering the movement state, the height of the tabletop is 1cm. At the end of the movement state, the height of the tabletop is 7cm, so the final movement range of the tabletop is 6cm.

In some optional embodiments, the fault detection mode is also used to indicate fault detection of at least one sensor. Therefore, after executing the detection instruction of fault detection in the fault detection mode, the controller may also perform fault detection on at least one sensor.

The process of performing fault detection on a sensor can include:

When fault detection is performed on the target sensor, the working information of the target sensor is obtained. The working information includes any one of the temperature fed back by the target sensor, the working voltage of the target sensor, and a status identifier used to indicate whether an error occurs in the target sensor;

According to the working information of the target sensor, the detection result corresponding to the target sensor is determined. The detection result corresponding to the target sensor includes whether there is a fault in the target sensor. The fault in the target sensor is used to indicate that at least one of the following situations occurs in the target sensor: the temperature fed back by the target sensor exceeds The normal temperature range, the target sensor's operating voltage outside the normal operating voltage range, and the status flag indicate that the target sensor has an error.

The normal temperature range and normal working voltage range of the target sensor can be stored in the storage unit of the operating bed in advance. After obtaining the temperature fed back by the target sensor or the current working voltage of the target sensor, the controller reads the normal temperature from the storage unit. range or normal operating voltage range, and determine whether the current temperature exceeds the normal temperature range through comparison, and determine whether the current operating voltage exceeds the normal operating voltage range.

The operating voltage of the target sensor can be obtained through the sensor feedback circuit connected to the target sensor, or it can also be obtained by detecting the voltage of a specific pin of the target sensor.

The status identification of the target sensor, specifically the Error Flag Block identification, which will feedback the reference voltage VREF. If VREF is in a low level state, it can be determined that the status identification indicates that no error has occurred in the target sensor. If VREF is in a high level state, It can be determined that the status flag indicates that an error has occurred on the target sensor.

It can be understood that when performing fault detection on sensors, the controller of the operating bed can determine at least one sensor that the fault detection mode indicates needs to be detected as the target sensor, and then detect these target sensors according to the above method to obtain the detection result of the target sensor. .

In some optional embodiments, the fault detection mode is also used to indicate fault detection of the storage unit. Therefore, after executing the detection instruction of fault detection in the fault detection mode, the controller may also perform fault detection on the storage unit.

The process of performing fault detection on a storage unit may include:

In the case of obtaining detection instructions for performing fault detection in fault detection mode, the method also includes:

When fault detection is performed on the storage unit, data verification is performed on the data stored in the storage unit to obtain a detection result of whether there is a fault in the storage unit.

The method of performing data verification on the data stored in the storage unit can be:

Part of the data stored in the storage unit is backed up in advance. The backup data can be stored in a different area of the storage unit from the original data, or can be stored in a memory that is different from the storage unit and is dedicated to storing backup data, or can be stored In the control terminal or third-party terminal equipment that is connected to the operating table.

When performing data verification, the original data is read from the storage unit, and the original data and the backup data are compared. If it is found that the original data and the backup data are inconsistent, the detection result of the storage unit is determined to be faulty. If If it is found that the original data and the backup data are consistent, it is determined that the detection result of the storage unit is that there is no fault.

It should be noted that in actual application scenarios, fault detection can be performed on any one or more of at least one movable component, at least one sensor and storage unit at the same time.

Optionally, after obtaining the detection instruction to perform fault detection in the fault detection mode, the fault detection can be performed periodically on at least one movable component, at least one sensor and storage unit according to a certain detection cycle. For example, the detection cycle can be 10 minutes. After obtaining the detection instruction to perform fault detection in the fault detection mode, every 10 minutes after the operating bed passes, according to the instructions of the fault detection mode, at least one movable component, at least one sensor and storage Perform fault detection on any one or more items in the unit.

When the operating table is in the fault detection mode and detects that at least one movable component, at least one sensor and the storage unit have a fault, in order to avoid performing erroneous actions, the controller of the operating table can control to stop performing compound posture movements. . Compound positional movements refer to movements that require simultaneous control of the movement of multiple movable components to complete. That is to say, when it is detected that at least one movable component, at least one sensor and the storage unit have a fault, the controller can prohibit controlling the movement of multiple movable components at the same time, but can allow controlling the movement of one movable component at a time.

The detection results obtained from the above-mentioned movable components, sensors and storage units can be output according to the output method described in step S203, which will not be described again.

This embodiment also provides an operating bed for performing the above fault detection method. The structure of the operating bed is as described above, wherein the storage unit (memory) of the operating bed can store computer programs, and the controller of the operating bed can read and execute the above computer program to implement the steps in the above method of this embodiment.

This embodiment also provides a fault detection system for performing the above fault detection method. The fault detection system may include an operating bed and a control terminal connected to the operating bed. The structure of the operating bed can be found in the previous article.

The control terminal may be at least one of a remote control, a wire controller of the operating bed, a control panel of the operating bed, a user terminal, a central station, a monitor, and other controllers of the operating bed.

The control terminal may include a memory and a processor. The memory is used to store computer programs, and the processor is used to execute the stored computer programs, thereby implementing the fault detection method provided by this embodiment.

Specifically, during the process of the control terminal executing the fault detection method provided by this embodiment, the control terminal can send a control instruction to the operating bed, thereby controlling one or more components of the operating bed to operate according to the fault detection method provided by this embodiment. For example, a control instruction is sent to control the first driving component of the operating table to work, and to control the second driving component to stop working; the control terminal can also obtain relevant data from the operating table, and implement the fault detection method in this embodiment based on the obtained data. Some steps include, for example, obtaining the position data of the movable component detected by the sensor of the operating table, determining the movement of the movable component based on the position data, and determining whether there is abnormal movement of the movable component based on the movement situation and the driving instructions.

This embodiment also provides a computer storage medium for storing a computer program. When the computer program is executed, it is used to implement the fault detection method provided by this embodiment.

Specifically, the computer storage medium may be a storage unit of the operating bed, or may be a memory of the control terminal.

Embodiment 2

This embodiment provides a fault detection method, which is applied to an operating bed. The structure of the operating bed is the same as that of the operating bed in Embodiment 1, and will not be described again.

Different from the operating bed in Embodiment 1, the operating bed in this embodiment is provided with two fault detection modes, which are respectively recorded as the first fault detection mode and the second fault detection mode.

The first fault detection mode is used to indicate fault detection of at least one driving component, and the second fault detection mode is used to indicate fault detection of at least one movable component.

Please refer to Figure 5, which is a flow chart of a fault detection method provided in this embodiment. The method may include the following steps.

S501: Obtain detection instructions for performing fault detection in the target fault detection mode.

If the target fault detection mode is the first fault detection mode, step S502 is executed; if the target fault detection mode is the second fault detection mode, step S504 is executed.

The first fault detection mode can also be called the automatic detection mode, and the second fault detection mode can also be called the real-time detection mode.

The detection instruction for performing fault detection in the first fault detection mode may be obtained by the control terminal of the operating bed sending the detection instruction to the operating bed according to the user's operation instruction.

Please refer to FIG. 6 , which is a schematic diagram of an interface for inputting detection instructions provided in this embodiment.

The interface shown in Figure 6 may be a setting interface displayed on the control terminal of the operating bed. After the control terminal displays the interface shown in Figure 6, the medical staff can click the "Fault Diagnosis" option on the interface, and then the control terminal generates a command to perform fault detection in the first fault detection mode according to the operation instructions of clicking the "Fault Diagnosis" option. A detection command is sent to the operating bed, thereby triggering the operating bed to perform fault detection in the first fault detection mode. For example, this method can be applied when the operating bed has only one fault detection mode.

In some optional embodiments, after clicking "Fault Diagnosis", the control terminal may also choose to perform fault detection in the first fault detection mode or in the second fault detection mode according to further operations by the medical staff. For example, this method can be applied when the operating bed has two fault detection modes. This application does not limit the fault detection mode of the operating bed.

Referring to Figure 7, the control terminal can display a mode selection interface as shown in Figure 7 after the medical staff clicks the "Fault Diagnosis" option shown in the interface of Figure 6. In this interface, the medical staff can select "First "Fault detection mode" or "second fault detection mode".

If the medical staff clicks "First fault detection mode", the control terminal generates a detection instruction to perform fault detection in the first fault detection mode according to the operation instruction, and sends the detection instruction to the operating bed; if the medical staff clicks " "Second fault detection mode", then the control terminal generates a detection instruction to perform fault detection in the second fault detection mode according to the operation instruction, and sends the detection instruction to the operating bed.

The detection instruction for performing fault detection in the second fault detection mode may be obtained by automatically obtaining the detection instruction from the storage unit when the operating bed is turned on. That is to say, the operating bed can automatically perform fault detection in the second fault detection mode after being turned on.

In addition to the above acquisition methods, the detection instructions for performing fault detection in the first fault detection mode and the detection instructions for performing fault detection in the second fault detection mode can also be the same as the detection instructions for performing fault detection in the fault detection mode in Embodiment 1. Obtain the method and won’t go into details.

Optionally, the first fault detection mode and the second fault detection mode can each be set to be executed when the operating bed is in a specific state. For example, it can be set that the fault detection is performed in the first fault detection mode only when the operating table is in a scene where it is determined that any movable component does not need to perform movement. For example, after the operating table is powered on, the operating table is not undergoing surgery. The first fault detection mode can be executed in any situation or in the scenario of regular fault detection of the operating bed. When the operating table is in a scenario where it is determined that any movable component can perform movement as needed, such as an operation in progress or a regular fault detection scenario, fault detection is performed in the second fault detection mode.

S502. Control any one of the at least one movable component to be unable to perform movement, perform fault detection on at least one driving component, and obtain a detection result corresponding to at least one driving component.

In step S502, for a specific method of performing fault detection on at least one driving component, please refer to the method of performing fault detection on the first driving component in Embodiment 1, which will not be described again here.

S503: Output the detection result corresponding to at least one driving component in at least one output component.

Steps S502 and S503 are equivalent to performing fault detection in the first fault detection mode.

As mentioned above, the operating bed may also include one or more other components among at least one sensor, a storage unit, and a power supply unit.

Therefore, in addition to being used to indicate a fault detection of at least one drive component, the first fault detection mode may also be used to indicate a fault detection of at least one other component. In this case, if the target fault detection mode is the first fault detection mode, this embodiment may also include:

Control any one of the at least one movable component not to perform movement, obtain detection results corresponding to other components, and output detection results corresponding to other components in at least one output component.

When performing fault detection on other components, for the method of performing fault detection on the sensor and the storage unit, please refer to the process of performing fault detection on the sensor and the process of performing fault detection on the storage unit in Embodiment 1, which will not be described again.

The method of performing fault detection on the power supply unit may be to obtain the electrical signal output by the power supply unit, such as the output voltage or the output current, and determine whether the electrical signal output by the power supply unit is within the preset signal range corresponding to the power supply unit, such as determining whether the output Check whether the voltage is within the preset voltage range, or determine whether the output current is within the preset current range. If the output electrical signal is within the preset signal range, it is determined that the detection result of the power supply unit is that there is no fault. If the output electrical signal is no longer within the preset signal range, it is determined that the detection result of the power supply unit is that there is a fault.

In the case where the first fault detection mode performs fault detection on a plurality of components including at least one drive assembly, the first fault detection mode is also used to indicate the detection sequence of the respective components;

If the target fault detection mode is the first fault detection mode, fault detection is performed in the first fault detection mode, which may specifically include performing fault detection on multiple components in a detection sequence.

When the first fault detection mode indicates performing fault detection on at least one drive component and at least one other component, the first fault detection mode may indicate a detection sequence of the drive component and other components so that detection is performed in the detection order.

For example, the first fault detection mode may indicate performing fault detection on the oil pump driving assembly, the backplate valve driving assembly, the angle sensor and the storage unit, and may indicate that the detection sequence is storage unit - angle sensor - oil pump driving assembly - The back plate valve driving assembly, whereby when fault detection is performed in the first fault detection mode, the storage unit is first detected, then the angle sensor is detected, then the oil pump driving assembly is detected, and finally the back plate valve driving assembly is detected.

When the first fault detection mode is only used to indicate the execution of fault detection on multiple driving components, the detection sequence of the multiple driving components may also be indicated, so that when the operating bed performs fault detection in the first fault detection mode, the detection is performed according to the instructions. Test each indicated drive component one by one in sequence.

Exemplarily, the first fault detection mode may indicate performing fault detection on the oil pump driving assembly, the back plate valve driving assembly and the leg plate valve driving assembly, and may indicate that the detection sequence is, oil pump driving assembly - leg plate valve driving assembly - back plate valve driving assembly. Plate valve driving assembly, whereby when performing fault detection in the first fault detection mode, fault detection is first performed on the oil pump driving assembly, then fault detection is performed on the leg plate valve driving assembly, and finally fault detection is performed on the back plate valve driving assembly .

Whether it is the detection sequence of multiple components including drive components and other components, or the detection sequence of multiple drive components, the way to determine the detection sequence can be any of the following:

First, while using the operating table, the medical staff can input operating instructions for setting the detection sequence through the control terminal of the operating table or the input component of the operating table, thereby setting the detection sequence referred to in the first fault detection mode.

Second, when the operating table leaves the factory, the manufacturer can write the preset detection sequence into the storage unit of the operating table. When performing fault detection in the first fault detection mode, the pre-written detection sequence can be read from the storage unit. sequence and perform detection based on this.

Optionally, if when performing fault detection in the first fault detection mode, the driving components and other components are detected one by one according to the indicated detection sequence, or multiple driving components are detected one by one, the currently being detected can be output in real time during the detection process. Instructions for components (which can be drive components or other components).

The instruction information can be output on at least one output component of the operating bed.

The instruction information can also be output on the display interface of the control terminal of the operating bed.

Indication information is used to indicate the component currently being inspected. The indication information may be in various forms, which is not limited in this embodiment. For example, the indication information may be the name of the component currently being detected, such as an oil pump driving assembly, or may be an icon representing the component currently being detected.

For example, please refer to FIG. 8 , which is a schematic diagram of an interface for displaying indication information of a component currently being detected on a control terminal provided in this embodiment. The control terminal may display the interface shown in FIG. 8 during the operation bed starting to perform fault detection in the first fault detection mode. Combined with Figure 6, the control terminal can display the interface shown in Figure 8 after the medical staff clicks "Fault Diagnosis".

When the interface shown in Figure 8 is displayed, the operating bed is detecting the lift valve driving assembly, so the control terminal displays the name of the currently detected component on the interface, that is, the "lift valve driving assembly".

S504: Control at least one movable component to perform motion, perform fault detection on at least one movable component, and obtain a detection result corresponding to at least one movable component.

S505, and output the detection result corresponding to at least one movable component in at least one output component.

Steps S504 and S505 are equivalent to performing fault detection in the second fault detection mode.

It should be noted that to perform fault detection in the second fault detection mode, detection can be performed periodically according to a certain detection period after obtaining the corresponding detection instruction. The detection period can be set according to the actual application scenario. In this embodiment No restrictions.

For example, the detection period can be set to 30 minutes. After the operating bed obtains the detection instruction to perform fault detection in the second fault detection mode, it will perform fault detection in the second fault detection mode every 30 minutes.

Optionally, if an instruction to perform fault detection in the first fault detection mode is obtained, the fault detection in the second fault detection mode may be suspended first, and after the fault detection in the first fault detection mode is completed, the fault detection in the first fault detection mode may be continued. The second fault detection mode performs fault detection.

In addition to the movable component, the second fault detection mode may also be used to instruct fault detection to be performed on other components of the surgical bed, including instructing to perform fault detection on at least one sensor of the surgical table, and to instruct fault detection to be performed on a storage unit of the surgical table. .

During the fault detection in the second fault detection mode, for the specific method of performing fault detection on at least one movable component, at least one sensor and the storage unit, you can refer to the process of performing fault detection on the movable component in Embodiment 1, and on The process of performing fault detection by the sensor and the process of performing fault detection on the storage unit will not be described again here.

The specific method of outputting the detection results in steps S503 and S505 can be referred to the method of outputting the detection results in step S203 of Embodiment 1, which will not be described again.

As an example, the detection results can be output by the control terminal through the interface shown in Figure 9. Figure 9 is a schematic diagram of an interface for outputting detection results provided in this embodiment.

The interface shown in Figure 9 can be displayed after completing a detection in the first fault detection mode, or after completing a detection in the second fault detection mode, without limitation.

Figure 9 is an example after completing the detection in the first fault detection mode, where the first fault detection mode is used to indicate the detection of the drive assembly and other components. After the detection is completed, it is found that the lift solenoid valve assembly and the back plate are present There is a fault in the sensor at the location, but there is no fault in other components, so the control terminal can only output the indication information (such as name) of the component with a detection result that is faulty and its detection result, that is, it displays "Lift solenoid valve fault" as shown in Figure 9 ” “Backplane sensor failure”.

The beneficial effect of this embodiment is that a first fault detection mode for detecting the driving component and a second fault detection mode for detecting the movable component are provided. When performing fault detection on the operating bed, one of them can be selected according to actual needs. One mode is used for detection, instead of having to perform fault detection on multiple components included in the operating table, which can shorten the time of each detection process.

Moreover, since the first fault detection mode only detects the driving component and the second fault detection mode only detects the movable component, it is helpful to quickly locate the faulty component when detecting in one of the modes.

The control terminal may include a memory and a processor, the memory is used to store a computer program, and the processor is used to execute the stored computer program, thereby implementing the fault detection method provided by this embodiment.

Specifically, during the process of the control terminal executing the fault detection method provided in this embodiment, the control terminal can perform the fault detection according to the preset trigger conditions (such as turning on the operating bed) and the operation of the medical staff (such as clicking "Fault" on the interface shown in Figure 6 "Diagnosis") generates a detection instruction to perform fault detection in the target fault detection mode, and then sends the detection instruction to the operating bed, thereby controlling the operating bed to perform fault detection in the corresponding first fault detection mode or second fault detection mode, and then controls the terminal Output the detection results.

It should be noted that although both Embodiment 1 and Embodiment 2 take the operating bed as an example for explanation, the fault detection method of Embodiment 1 and Embodiment 2 can not only be applied to detecting faults of the operating bed, but can also be applied to other devices such as Medical equipment with the structure shown in Figure 1, such as electric limb rehabilitation equipment, etc.

Among them, the movable components of the medical device may form a support part, or may not form a support part.

The method of performing fault detection on medical equipment is consistent with the method of performing fault detection on the operating bed in

Embodiments

1 and 2, and will not be described again.

Embodiment 3
