Technical Field

[0001] The present invention relates to the field of intelligent control technology, and in particular to a display control method, device and medical equipment. Background Art

[0002] To facilitate use in different areas of the hospital, rechargeable batteries are installed on medical equipment to provide energy for the equipment, making it convenient for the medical equipment to be used in various areas of the hospital while ensuring that the medical equipment is not disconnected from the power supply. For example, rechargeable batteries, such as lithium batteries, are installed in medical equipment, but the display in the medical equipment usually accounts for more than half of the total power consumption of the medical equipment. According to statistics, the time medical staff spend facing the display and the time away from the display when using medical equipment account for approximately 4:6, which means that medical staff spend nearly 60% of their time doing nursing, dispensing medicine, and diagnosis work. When medical staff leave the medical equipment, the display that is always in the display state will seriously waste the power of the medical equipment, resulting in the medical equipment using rechargeable batteries needing to be frequently charged, reducing the attendance efficiency of the medical equipment and affecting the normal use of the medical equipment. Therefore, the existing technical methods have the problem of the display consuming the power of the medical equipment too quickly. Summary of the Invention

[0020] The controller is further configured to control the display to turn on or display a first brightness according to the first current signal, and to control the display to display a second brightness according to the second current signal.

[0021] Preferably, the first sensor is further configured to generate a third current signal when a vibration signal within a preset range is detected;

[0022] The first sensor is further configured to block the first current signal or the second current signal according to the third current signal.

[0023] Preferably, the detection signal is an infrared signal of a second wavelength, and the second sensor generates the second current signal when detecting a reflection signal of the second wavelength infrared signal. The first sensor includes a filter, a pyroelectric detection unit, a vibration detection unit and a switching circuit.

When a medical professional stands still in front of the display, they do not generate a changing first-wavelength infrared signal, so the first sensor cannot detect their presence. The second sensor, however, detects the medical professional standing still in front of the display and controls the display to a second brightness, allowing the medical professional to use the display normally. The first and second sensors work together to accurately detect the presence of a medical professional, turning the display on when the medical professional is present and off when the medical professional leaves. This intelligent control of the display's on and off saves energy, thereby increasing the usability of medical equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] See also Figure 1 and Figure 2 , Figure 1 is a flow chart of a method for controlling a display provided by an embodiment of the present invention, Figure 2A schematic diagram of the structure of a display control terminal provided in an embodiment of the present invention; the control method of the display is applied to medical equipment, which can be implemented as a display control terminal 10, comprising a controller 11 and a display 12, a first sensor 13, a second sensor 14 and a rechargeable battery 15, each of which is connected to the controller 11 by signal. The display 12, the first sensor 13 and the second sensor 14 are all connected to the controller 11 to realize the transmission of data information. The control method of the display is executed by application software installed in the controller 11. The first sensor 13 is used to detect infrared radiation emitted by the human body, and the second sensor 14 is used to detect the reflected signal emitted by it. Among them, the display 12 of the display control terminal 10 can be used as a display device for displaying nursing information, medication information or diagnostic information. The first sensor 13 can be a sensor for detecting human movement, and the second sensor 14 can be a sensor for detecting whether a human body is approaching. The controller 11 can receive the first detection information of the first sensor 13 and the second detection information of the second sensor 14, and send a control instruction to the terminal device of the display, such as an MCU control chip, etc. The rechargeable battery 15 can be a battery for powering other components, such as a lithium battery. Figure 1 As shown, the method includes steps S110 to S140.

[0038] S110 : If the first sensor detects a changing infrared signal of a first wavelength, a first current signal is generated, and the display is controlled to turn on or display at a first brightness according to the first current signal.

[0039] It can be understood that the central wavelength of infrared radiation radiated by the human body is 9um to 10um, the wavelength range of the first wavelength infrared signal is 7um to 10um, and the first sensor can sense the changing infrared radiation of the human body.

[0040] Specifically, the first sensor is activated to enable the first sensor to detect infrared signals entering a first sensing range in real time. If the first sensor detects a changing first wavelength infrared signal, indicating that a medical professional has entered the first sensing range, a first current signal is generated and sent to a controller. The controller receives the first current signal and controls the display to turn on or display at a first brightness based on the first current signal. The first sensor may be a pyroelectric sensor.

[0041] The technical method in the embodiment of the present application is applied in the medical field. In the medical field, the response speed of medical equipment is required to be high. Therefore, after the human body enters the first sensing range, the display is turned on or the display is adjusted to the first brightness. This can improve the response speed of the display in the medical equipment, and medical staff do not need to wait when they need to actually check the content displayed on the display.

[0042] S120: Control the second sensor to transmit a detection signal.

[0043] The controller controls the second sensor to transmit a detection signal.

[0044] Specifically, the controller sends an opening instruction to the second sensor to control the second sensor to open.

[0045] In an embodiment of the present application, in order to further reduce the power consumption of the medical device, when the medical staff does not enter the first sensing range, the controller turns off the second sensor. When the medical staff enters the first sensing range, the controller turns on the second sensor to enable the second sensor to operate.

[0046] In other embodiments, the second sensor is always in the on state.

[0047] S130: If the second sensor detects a reflection signal of the detection signal, a second current signal is generated, and the display is controlled to display at a second brightness according to the second current signal.

[0048] In an embodiment of the present application, a second sensor is activated to enable the second sensor to detect in real time whether a detection signal contains a transmission signal. If the second sensor detects a reflection signal of the detection signal, indicating that a medical staff member has blocked the detection signal transmitted by the second sensor, the second sensor generates a second current signal and sends the second current signal to a controller. The controller receives the second current signal and controls the display to display at a second brightness according to the second current signal. The second sensor may be an infrared ranging sensor.

[0049] S140: If the first sensor or the second sensor detects a vibration signal within a preset range, a third current signal is generated; and the first current signal or the third current signal is blocked according to the third current signal.

[0050] Under normal circumstances, medical personnel do not operate mobile medical equipment. When medical personnel push the medical device while operating the display, their attention is focused on the display. Therefore, they are likely to bump into pedestrians or walls while moving the medical device, posing a safety hazard. Therefore, medical personnel do not operate mobile medical equipment. Although the purpose of this application is to turn on the display as soon as the medical personnel enters the sensing range of the first sensor, thereby improving the timeliness of the display display and allowing medical personnel to operate the display in a timely manner, during the movement of the medical device, medical personnel will not operate the display. If the display remains in the display state at this time, it will result in a waste of power in the medical device. In this embodiment, the first sensor is capable of detecting the vibration of the medical device. If the first sensor detects a vibration signal within a preset range, indicating that the medical device is in a mobile state, the first sensor generates a third current signal and sends the third current signal to the controller. The controller receives the third current signal and, based on the third current signal, controls the first sensor to block the first current signal, thereby turning off the display, thereby achieving further energy saving of the display.

[0051] Specifically, the detection signal is a second wavelength infrared signal, the second sensor is an infrared ranging sensor, and the second sensor generates the second current signal when detecting the reflection signal of the second wavelength infrared signal. The first sensor includes a filter, a pyroelectric detection unit, a vibration detection unit and a switching circuit. The filter is arranged above the pyroelectric detection unit to prevent infrared signals other than the first wavelength from passing through. The pyroelectric detection unit generates the first current signal when detecting a changing first wavelength infrared signal. The vibration detection unit generates the third current signal when detecting vibration within a preset range. The switching circuit then blocks the first current signal according to the third current signal.

[0052] In one embodiment, step S130 further includes step S1301 .

[0053] S1301: If the second sensor does not detect the reflected signal of the detection signal, control the display to display at a third brightness or at the first brightness.

[0054] If the second sensor does not detect a reflection of the detection signal, indicating that the medical staff has left the second sensing range, the second sensor does not generate a second current signal, and the controller controls the display to display at a third brightness or the first brightness. The third brightness is greater than the first brightness.

[0055] In one embodiment, step S1301 further includes step S1302.

[0056] S1302: If the first sensor does not detect the changed first wavelength infrared signal, or if the first sensor does not detect the changed first wavelength infrared signal within a preset time, the controller controls the display to turn off or display at a fourth brightness.

[0057] In one embodiment, if the first sensor does not detect a changed first wavelength infrared signal, indicating that the medical staff has left the first sensing range, the first sensor does not generate a first current signal. Therefore, the controller controls the display to turn off or display at a fourth brightness. Turning off the display can be controlling the display to enter a dormant state, in which no information is displayed. The turned-off display can again receive other control instructions from the controller, thereby terminating the dormant state. Specifically, the fourth brightness can be the display's lowest display brightness.

[0058] In an alternative embodiment, if the first sensor does not detect a changing first-wavelength infrared signal, the controller controls the display to turn off. If the first sensor detects a changing first-wavelength infrared signal, the controller controls the display to turn on. In real-world situations, medical personnel often move back and forth between medical equipment and patients. In these situations, they are not truly away from the medical equipment, but rather are away for work purposes. This can cause the display to frequently turn on and off, thereby shortening its lifespan. In this embodiment, if the first sensor does not detect a changing first-wavelength infrared signal within a preset time, the controller controls the display to turn off or set the brightness to a fourth level. With this configuration, if the first sensor does not detect a changing first-wavelength infrared signal, the controller does not immediately turn off the display. Instead, it waits until the preset time has passed to determine that the medical personnel has truly left the medical equipment before turning off the display. This prevents frequent turning on and off of the display, thereby ensuring the lifespan of the medical equipment. In this embodiment, the preset time is 3 seconds. It will be appreciated that in alternative embodiments, the preset time is not limited to 3 seconds and can be determined based on actual circumstances.

[0059] In one embodiment, step S1302 further includes step S1303.

[0060] S1303: Send a shutdown instruction to the second sensor to control the second sensor to shut down.

[0061] Specifically, after sending the fourth control instruction to the display, the controller may also send a shutdown instruction to the second sensor. Upon receiving the shutdown instruction, the second sensor may shut down and enter a standby state. If the controller determines that the first detection information indicates a change in infrared radiation, it may send an on instruction to the second sensor to control the second sensor to turn on, thereby further achieving the effect of energy saving for the display.

[0062] In one embodiment,

[0063] S130 specifically includes: controlling the brightness of the display according to the intensity change of the reflected signal.

[0064] Specifically, the brightness of the display can be controlled based on the intensity change of the reflected signal of the detection signal detected by the second sensor. A greater intensity of the reflected signal indicates a closer distance between the medical staff and the display, and the controller accordingly brightens the display. A smaller intensity of the reflected signal indicates a greater distance between the medical staff and the display, and the controller accordingly dims the display. In other words, the display brightness is dynamically adjusted based on the intensity change of the reflected signal, thereby improving the accuracy of display brightness control and further achieving energy-saving effects on the display.

[0065] Specifically, the corresponding target brightness value may be calculated according to a preset calculation formula and the intensity of the reflected signal, so as to control the display to adjust the brightness according to the target brightness value.

[0066] For example, the target brightness value can be calculated using formula (1).

[0067] M = A × (1-F0 / F) (1);

[0068] Wherein, M is the calculated target brightness value, A is the basic brightness value of the display, which can be the maximum brightness value of the display or a brightness value close to the maximum brightness value; F0 is the preset reflection signal intensity; F is the intensity change value of the reflection signal in the second detection information, and F>F0.

[0069] In another embodiment, step S103 specifically includes: obtaining the time difference between the emitted second wavelength infrared signal and the received reflected signal; controlling the display to display the second brightness according to the time difference, wherein the brightness value of the second brightness is greater than the brightness value of the first brightness.

[0070] Specifically, the second sensor obtains the time difference between the emitted second wavelength infrared signal and the received reflected signal, and sends the time difference to the controller. The controller receives the time difference sent by the second sensor and controls the display to display at the second brightness according to the time difference. The larger the time difference, the farther the medical staff is from the second sensor. In this case, the controller accordingly lowers the brightness of the display. As the time difference becomes smaller, the closer the medical staff is from the second sensor. In this case, the controller accordingly increases the brightness of the display. This not only facilitates the user's normal use of the display, but also intelligently adjusts the brightness of the display, thereby further achieving the effect of energy saving of the display.

[0071] In this embodiment, if the first sensor detects a changing first wavelength infrared signal, it generates a first current signal, and controls the display to turn on or display at the first brightness according to the first current signal; controls the second sensor to emit a detection signal; and if the second sensor detects a reflection signal of the detection signal, it generates a second current signal, and controls the display to display at the second brightness according to the second current signal. In the above method, the first sensor can detect the changing first wavelength infrared signal to confirm that the medical staff has entered the first sensing range and then turn on the display, and then the second sensor can detect the reflection signal of the detection signal to confirm that the medical staff has entered the second sensing range and then adjust the display to the second brightness; in this way, when the first sensor detects that the medical staff has generated a changing first wavelength infrared signal, it indicates that the medical staff is moving near the medical equipment. At this time, the controller controls the display to turn on or display at the first brightness, so that the display can quickly enter the display state, thereby improving the timeliness of the display, so that the medical staff can operate the display in time. When a medical professional stands still in front of the display, they do not generate a changing first-wavelength infrared signal, so the first sensor cannot detect their presence. The second sensor, however, detects the medical professional standing still in front of the display and controls the display to a second brightness, allowing the medical professional to use the display normally. The first and second sensors work together to accurately detect the presence of a medical professional, turning the display on when the medical professional is present and off when the medical professional leaves. This intelligent control of the display's on and off saves energy, thereby increasing the usability of medical equipment.

[0072] An embodiment of the present invention further provides a control device for a display, comprising a display, a controller, a first sensor, and a second sensor, wherein the first sensor and the second sensor are spaced apart and arranged at preset positions on the display.

[0073] The first sensor is configured to generate a first current signal upon detecting a changing first wavelength infrared signal.

[0074] The controller controls the second sensor to transmit a detection signal, and the second sensor is configured to generate a second current signal upon detecting a reflection signal of the detection signal.

[0075] The controller is further configured to control the display to turn on or display a first brightness according to the first current signal, and to control the display to display a second brightness according to the second current signal.

[0076] The first sensor is further configured to generate a third current signal when a vibration signal within a preset range is detected.

[0077] The first sensor is further configured to block the first current signal or the second current signal according to the third current signal.

[0078] The detection signal is an infrared signal of the second wavelength. The second sensor generates the second current signal when detecting a reflection signal of the infrared signal of the second wavelength. The first sensor includes a filter, a pyroelectric detection unit, a vibration detection unit and a switching circuit. The filter is arranged above the pyroelectric detection unit to prevent infrared signals other than the first wavelength from being received by the pyroelectric detection unit. The pyroelectric detection unit generates the first current signal when detecting a changing infrared signal of the first wavelength. The vibration detection unit generates the third current signal when detecting a vibration within a preset range. The switching circuit blocks the first current signal or the second current signal according to the third current signal.

[0079] like Figure 3 As shown, in this embodiment, the switching circuit includes: a first resistor, a second resistor, a third resistor, a first MOS transistor, and a second MOS transistor. The first end of the pyroelectric detection unit is connected to one end of the first resistor and electrically connected, the second end of the pyroelectric detection unit is connected to the S pole of the first MOS transistor, and the third end of the pyroelectric detection unit is grounded. The other end of the first resistor (point a) is connected to the G pole of the first MOS transistor, and the D pole of the first MOS transistor is connected to the controller. One end of the vibration detection unit is grounded, and the other end is connected to the second parallel terminal b. One end of the second resistor is electrically connected, and the other end is connected to the second parallel terminal b. The second parallel terminal b is connected to the G pole of the second MOS transistor. The S pole of the second MOS transistor is grounded. The D pole of the second MOS transistor is connected to one end of the third resistor, and the other end of the third resistor is connected to the G pole of the second MOS transistor. The resistance of the first resistor is 10K, and the resistance of the second and third resistors are both 1K.

[0080] Specifically, when the medical device is in a static state, the vibration detection unit is in an off state. Since the resistance of the vibration detection unit in the off state approaches infinity, current can only flow from the second resistor into the G pole of the second MOS transistor, causing a voltage difference to form between the G and S poles of the second MOS transistor, thereby turning on the D and S poles of the second MOS transistor, causing the third resistor and the ground to be at the same potential. Because the third resistor is much smaller than the first resistor, according to the principle of resistor voltage division, a voltage difference can be formed between the G and S poles of the first MOS transistor, turning on the D and S poles of the first MOS transistor, allowing the signal generated by the pyroelectric detection unit to be transmitted to the controller through the first MOS transistor, thereby enabling the controller to control the display.

[0081] When the medical device is pushed to move, the vibration detection unit is in a conducting state. Since one end of the vibration detection unit is grounded and the other end is connected to the G pole of the second MOS tube, the G pole of the second MOS tube is directly grounded and is at the same potential as the S pole, so that the D pole and S pole of the second MOS tube are in a disconnected state. At this time, the resistance values ​​of the D pole and S pole of the second MOS tube tend to infinity. Since the resistance of the second MOS tube is much greater than the first resistance, according to the resistance voltage divider principle, the G pole and S pole of the first MOS tube are at the same potential, resulting in the D pole and S pole of the first MOS tube being in a disconnected state, so that the signal generated by the pyroelectric detection unit cannot be transmitted to the controller through the first MOS tube.

[0082] like Figure 4 As shown, an embodiment of the present invention further provides a medical device 100, which includes a device body 10, a handle 20 and a control device 30 of a display as in any of the above embodiments, wherein the bottom of the device body 10 includes movable casters 40, the display 31 is arranged on the top of the device body 10, the handle 20 is arranged on the back of the device body 10 relative to the display 31, and the first sensor 50 and the second sensor 60 are arranged on the front of the display 31 and are located between the bottom and the top.

[0083] Specifically, the handle 20 is set on the back of the device body 10 relative to the display 31, and the first sensor 50 and the second sensor 60 are set on the front of the display 31. When the medical staff pushes the device body 10 to move by the handle 20, the medical staff will not block the detection signal emitted by the second sensor 60, so that when the first sensor 50 detects that the device body 10 vibrates, it generates a third current signal and sends the third current signal to the controller. The controller receives the third current signal and controls the first sensor 50 to block the first current signal according to the third current signal, thereby turning off the display 31, so as to avoid the phenomenon that the display 30 cannot be turned off due to the medical staff blocking the detection signal sent by the second sensor 60 when the device body 10 moves, thereby ensuring that the display 31 can reliably achieve the energy-saving effect.

[0084] The above display control method can be implemented in the form of a computer program. The computer program can be used in Figure 5 The display control device can be implemented as a computer device.

[0085] See also Figure 5 , Figure 5 1 is a schematic block diagram of a computer device provided by an embodiment of the present invention. The computer device may be a controller for executing a method for controlling a display to receive first detection information from a first sensor and second detection information from a second sensor, and issue a control instruction to the display.

[0086] See Figure 5 The computer device 500 includes a processor 502 , a memory, and a network interface 505 connected via a system bus 501 , wherein the memory may include a storage medium 503 and an internal memory 504 .

[0087] The storage medium 503 may store an operating system 5031 and a computer program 5032. When the computer program 5032 is executed, the processor 502 may execute a method for controlling a display. The storage medium 503 may be a volatile storage medium or a non-volatile storage medium.

[0088] The processor 502 is used to provide computing and control capabilities to support the operation of the entire computer device 500.

[0089] The internal memory 504 provides an environment for the operation of the computer program 5032 in the storage medium 503. When the computer program 5032 is executed by the processor 502, the processor 502 can execute the display control method.

[0090] The network interface 505 is used for network communication, such as providing data information transmission.
