Technical Field

[0002] Traditionally, low power consumption is achieved by using the low-power mode of the MCU (Microcontroller Unit) and controlling peripherals, clocks, kernels, etc. through programming. However, some circuits in the circuit still consume battery power. When this low-power mode is applied to medical devices, problems will occur.

[0034] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] In one embodiment, as Figure 1 shown, a wake-up detection circuit is provided, which includes: a first electronic control switch K3 and a trigger switch S1;

[0036] The first end of the trigger switch S1 is connected to the first normally closed contact of the first electronic control switch K3, and the second end of the trigger switch S1 is connected to the second normally closed contact of the first electronic control switch K3.

[0037] The first switch terminal of the first electronic control switch K3 is connected to the first enabling terminal ON / OFF+ of the battery module, and the second switch terminal of the first electronic control switch K3 is connected to the second enabling terminal ON / OFF- of the battery module;

[0038] The first electrically controlled switch K3 is configured such that when the first electrically controlled switch K3 is not powered on, the first switch terminal of the first electrically controlled switch K3 is connected to the first normally closed contact of the first electrically controlled switch K3, and the second switch terminal of the first electrically controlled switch K3 is connected to the second normally closed contact of the first electrically controlled switch K3. When the trigger switch S1 is closed, conduction is established between the first enable terminal and the second enable terminal of the battery module.

[0039] In this embodiment, when the first electrically controlled switch K3 is not powered on, the first switch terminal and the second switch terminal are not attracted, the first switch terminal remains connected to the first normally closed contact, and the second switch terminal remains connected to the second normally closed contact. At this time, if the trigger switch S1 is not closed, the connection state between the first enable terminal and the second enable terminal of the battery module is open. When the trigger switch S1 is closed, conduction is established between the first enable terminal and the second enable terminal of the battery module, causing the battery module to switch from the low-power mode to the startup mode. In the electrical control switches of the embodiments herein, the switch terminals are movable terminals. When the power input terminal of the electrical control switch is not powered on, the switch terminal remains connected to the normally closed contact; when the power input terminal of the electrical control switch is powered on, the switch terminal disconnects from the normally closed contact and is attracted to connect to the normally open contact.

[0040] The trigger switch S1 can be a push-button switch, a touch switch, a rotary switch, or a switch that uses the user's hand as a conductor to conduct. In one embodiment, the trigger switch S1 is a normally open switch that conducts when subjected to the force of the user and disconnects when not subjected to an external force.

[0041] In one embodiment, the power input terminal of the first electrically controlled switch K3 is connected to the battery module. Thus, when the battery module is started, the first switch terminal and the second switch terminal of the first electrically controlled switch K3 will be attracted, thereby disconnecting from the first normally closed contact and the second normally closed contact respectively. This situation will be elaborated in the subsequent part of the text.

[0042] In this embodiment, pin 2 of the first electrically controlled switch K3 is connected to the first end of the trigger switch S1 as the first normally closed contact, pin 7 of the first electrically controlled switch K3 is connected to the second end of the trigger switch S1 as the second normally closed contact, pin 3 of the first electrically controlled switch K3 is connected to the first enable terminal ON / OFF+ of the battery module as the first switch terminal, and pin 6 of the first electrically controlled switch K3 is connected to the second enable terminal ON / OFF- of the battery module as the second switch terminal. Thus, when the trigger switch S1 is closed, conduction is established between the first enable terminal ON / OFF+ and the second enable terminal ON / OFF- of the battery module through the connection between pin 2 and pin 3 and the connection between pin 7 and pin 6 of the first electrically controlled switch K3.

[0043] In this embodiment, when the first enable terminal and the second enable terminal of the battery module are disconnected, the battery module maintains a low-power state, thereby avoiding power loss of the battery module. Only when the user turns on the touch switch, the first enable terminal and the second enable terminal of the battery module are conducted, a loop is formed between the first enable terminal and the second enable terminal of the battery module, so that the battery module switches from the low-power mode to the start mode, and the battery module is awakened, thus playing a role in saving the energy consumption of the battery module well. Therefore, in the low-power mode of the battery module, only by turning on the trigger switch S1 can the battery module be triggered to wake up, without additionally powering the detection circuit. The battery module does not supply power externally in the low-power mode, effectively avoiding the situation that the battery module runs out of power after supplying power externally for a long time, and effectively extending the power storage time of the battery module.

[0044] In one embodiment, please combine Figure 1 and Figure 2 , the wake-up detection circuit further includes a second electronic control switch K4. The third switch terminal of the second electronic control switch K4 is connected to the first terminal of the trigger switch S1. The second terminal of the trigger switch S1 is used to be connected to the main control module. The first normally open contact of the second electronic control switch K4 is used to be connected to the second power supply. The power input terminal of the second electronic control switch K4 is connected to the power output terminal of the battery module. The second electronic control switch K4 is configured such that when the power input terminal of the second electronic control switch K4 receives the power of the battery module, the third switch terminal of the second electronic control switch K4 is connected to the first normally open contact of the second electronic control switch K4, so that the power of the second power supply is sequentially transmitted to the main control module through the first normally open contact of the second electronic control switch K4, the third switch terminal of the second electronic control switch K4, and the trigger switch S1.

[0045] In this embodiment, when the power input terminal of the second electronic control switch K4 is not powered on, the switch terminal of the second electronic control switch K4 remains connected to the normally closed contact; when the power input terminal of the second electronic control switch K4 is powered on, the switch terminal of the second electronic control switch K4 disconnects from the normally closed contact, and the switch terminal is attracted to connect to the normally open contact.

[0046] Specifically, the power input terminal of the second electronic control switch K4 includes a third power input terminal and a fourth power input terminal. The third power input terminal of the second electronic control switch K4 is connected to the power output terminal of the battery module, and the fourth power input terminal of the second electronic control switch K4 is used for grounding. In this embodiment, the second electronic control switch K4 is a relay. For example, the second electronic control switch K4 is the second relay. The first end of the coil of the second electronic control switch K4 is the third power input terminal, and the second end of the coil of the second electronic control switch K4 is the fourth power input terminal. In this way, when the third power input terminal receives the power from the battery module, the coil of the second electronic control switch K4 is energized, and the third switch terminal of the second electronic control switch K4 is attracted, so that the third switch terminal is connected to the first normally open contact of the second electronic control switch K4, so that the power of the second power supply is sequentially transmitted to the main control module through the first normally open contact of the second electronic control switch K4, the third switch terminal of the second electronic control switch K4, and the trigger switch S1.

[0047] In this embodiment, the second power supply provides a voltage of +24V. The second power supply is connected to the first normally open contact of the second electronic control switch K4 through the resistor R79. This first normally open contact is the pin 5 of the second electronic control switch K4. The third switch terminal of the second electronic control switch K4 is the pin 6 of the second electronic control switch K4. It can be seen from the Handle node in the figure that the pin 6 of the second electronic control switch K4 is connected to the first end of the trigger switch S1, and the second end of the trigger switch S1 is connected to the main control module as the node KIN1.

[0048] In addition, in this embodiment, the pin 1 of the second electronic control switch K4 is used as the third power input terminal and is connected to the VCC power supply provided by the battery module. The pin 8 of the second electronic control switch K4 is used as the fourth power input terminal and is used for grounding. Moreover, the third power input terminal of the second electronic control switch K4 is connected to the cathode of the diode D58, and the fourth power input terminal of the second electronic control switch K4 is connected to the anode of the diode D58. By setting the diode D58, the battery module can make the output current of the second electronic control switch K4 conduct unidirectionally.

[0049] In this way, when the coil of the second electronic control switch K4 is energized and the third switch terminal is attracted to the first normally open contact, the connection between the second power supply and the main control module is conducted, triggering the main control module to work.

[0050] Specifically, when the trigger switch S1 is closed again, a trigger signal will be sent to the main control module to perform other actions (such as locking the wheels, etc.).

[0051] That is to say, at low power consumption, the trigger switch S1 is closed for the first time to wake up the battery. The first enabling end and the second enabling end of the battery module are electrically connected. After the battery is woken up, if the trigger switch S1 is pressed again or the user keeps pressing the trigger switch S1 without releasing it after the first closure, the second electronic control switch K4 will be powered on at this time. After the third switch terminal of the second electronic control switch K4 is attracted to the first normally open contact, the connection between the second power supply and the main control module is electrically connected, triggering the main control module to work and perform other actions.

[0052] In one embodiment, as Figure 3 shown, the wake-up detection circuit further includes an opto-isolator U1. The input end of the opto-isolator U1 is connected to the second end of the trigger switch S1, and the output end of the opto-isolator U1 is used to connect to the main control module.

[0053] In this embodiment, the opto-isolator U1 is an opto-coupler. Pin 1 of the opto-isolator U1 is used as the input end and is connected to node KIN1, that is, pin 1 of the opto-isolator U1 is connected to the second end of the trigger switch S1. Pin 16 of the opto-isolator U1 is used as the output end and is connected to the main control module (MCU). In this embodiment, when the coil of the second electronic control switch K4 is powered on and the third switch terminal is attracted to the first normally open contact, the opto-isolator U1 works and sends a signal through the output end, making the connection between the main control module and the power supply DVCC electrically connected, so that the main control module is powered on and the main control module is woken up. By connecting the opto-isolator U1 between the second electronic control switch K4 and the main control module, electrical isolation between the second electronic control switch K4 and the main control module is achieved.

[0054] In one embodiment, please refer to Figure 1 , the wake-up detection circuit further includes a third electronic control switch K2. The power input end of the third electronic control switch K2 is connected to the power output end of the battery module. The fourth switch terminal of the third electronic control switch K2 is connected to the first enabling end of the battery module. The second normally open contact of the third electronic control switch K2 is connected to the second enabling end of the battery module; the third electronic control switch K2 is configured such that when the power input end of the third electronic control switch K2 receives the power from the battery module, the fourth switch terminal of the third electronic control switch K2 is connected to the second normally open contact of the third electronic control switch K2.

[0055] In this embodiment, when the power input end of the third electronic control switch K2 is not powered on, the switch terminal of the third electronic control switch K2 remains connected to the normally closed contact; when the power input end of the third electronic control switch K2 is powered on, the switch terminal of the third electronic control switch K2 disconnects from the normally closed contact, and the switch terminal is attracted to connect to the normally open contact.

[0056] Specifically, the power input terminal of the third electronic control switch K2 includes a fifth power input terminal and a sixth power input terminal. The fifth power input terminal of the third electronic control switch K2 is connected to the power output terminal of the battery module, and the sixth power input terminal of the third electronic control switch K2 is grounded. In this embodiment, the third electronic control switch K2 is a relay. For example, the third electronic control switch K2 is the third relay. The first end of the coil of the third electronic control switch K2 is the fifth power input terminal, and the second end of the coil of the third electronic control switch K2 is the sixth power input terminal. In this way, when the fifth power input terminal receives the power from the battery module, the coil of the third electronic control switch K2 is energized, and the fourth switch terminal of the third electronic control switch K2 is attracted, so that the fourth switch terminal is connected to the second normally open contact of the third electronic control switch K2. In this way, the first enable terminal and the second enable terminal of the battery module are connected through the fourth switch terminal and the second normally open contact of the third electronic control switch K2, so that the first enable terminal and the second enable terminal of the battery module form a loop.

[0057] In this embodiment, pin 1 of the third electronic control switch K2 is used as the fifth power input terminal and is connected to the VCC power supply provided by the battery module. Pin 8 of the third electronic control switch K2 is used as the sixth power input terminal and is grounded. Pin 3 of the third electronic control switch K2 is used as the fourth switch terminal and is connected to the first enable terminal of the battery module. Pin 4 of the third electronic control switch K2 is used as the second normally open contact and is connected to the second enable terminal of the battery module.

[0058] In addition, in this embodiment, the fifth power input terminal of the third electronic control switch K2 is connected to the cathode of the diode D61, and the sixth power input terminal of the third electronic control switch K2 is connected to the anode of the diode D61. By setting the diode D61, the current output by the battery module to the third electronic control switch K2 can be made to conduct unidirectionally.

[0059] In one embodiment, as Figure 1 shown, the first power input terminal of the first electronic control switch K3 is connected to the power output terminal of the battery module, the second power input terminal of the first electronic control switch K3 is connected to the fifth switch terminal of the third electronic control switch K2, and the third normally open contact of the third electronic control switch K2 is grounded;

[0060] The third electronic control switch K2 is configured such that when the power input terminal of the third electronic control switch K2 receives the power from the battery module, the fifth switch terminal of the third electronic control switch K2 is connected to the third normally open contact of the third electronic control switch K2;

[0061] The first electric control switch K3 is set such that when the power input terminal of the first electric control switch K3 receives the electric energy from the battery module, the first switch terminal of the first electric control switch K3 disconnects from the first normally closed contact of the first electric control switch K3, and the second switch terminal of the first electric control switch K3 disconnects from the second normally closed contact of the first electric control switch K3.

[0062] In this embodiment, when the power input terminal of the third electric control switch K2 receives electric energy, the fifth switch terminal of the third electric control switch K2 is attracted, so that the fifth switch terminal of the third electric control switch K2 is connected to the third normally open contact of the third electric control switch K2. As a result, the second power input terminal of the first electric control switch K3 is grounded through the fifth switch terminal and the third normally open contact of the third electric control switch K2. Furthermore, the power output terminal of the battery module passes through the first power input terminal of the first electric control switch K3 and the first power input terminal to be grounded, forming a loop, thereby energizing the first electric control switch K3.

[0063] In this embodiment, the first electric control switch K3 can be a relay. For example, the first electric control switch K3 is the first relay. The first end of the coil of the first electric control switch K3 is the first power input terminal, and the second end of the coil of the first electric control switch K3 is the second power input terminal. When the coil of the third electric control switch K2 is energized, the fifth switch terminal of the third electric control switch K2 is attracted, so that the fifth switch terminal of the third electric control switch K2 is connected to the third normally open contact of the third electric control switch K2. Then, the power output terminal of the battery module passes through the first power input terminal of the first electric control switch K3 and the first power input terminal to be grounded, forming a loop. The coil of the first electric control switch K3 is energized, and the first switch terminal and the second switch terminal of the first electric control switch K3 are attracted and connected to the normally open contacts of the first electric control switch K3 respectively, and disconnect from the first normally closed contact and the second normally closed contact of the first electric control switch K3 respectively. Since at this time when the coil of the third electric control switch K2 is energized, the fourth switch terminal of the third electric control switch K2 is connected to the second normally open contact of the third electric control switch K2, the first enable terminal and the second enable terminal of the battery module are stably connected through the fourth switch terminal and the second normally open contact of the third electric control switch K2. In this way, even if the first switch terminal and the second switch terminal of the first electric control switch K3 are disconnected from the first normally closed contact and the second normally closed contact respectively, the connection between the first enable terminal and the second enable terminal of the battery module can be maintained.

[0064] That is to say, the third electronic control switch K2 is energized first, and the first electronic control switch K3 is energized later. In this way, when the normally open contact of the third electronic control switch K2 is closed, the fourth switch terminal of the third electronic control switch K2 is connected to the second normally open contact, maintaining the conduction between the first enable terminal and the second enable terminal of the battery module. Moreover, after the normally open contact of the third electronic control switch K2 is closed, the coil of the first electronic control switch K3 is conducted, and the normally closed contact of the first electronic control switch K3 is disconnected. It is equivalent to that the normally closed contact of the first electronic control switch K3 is disconnected after a delay after the trigger switch S1 is conducted, which can effectively avoid the disconnection in the conduction between the first enable terminal and the second enable terminal of the battery module.

[0065] In this embodiment, pin 1 of the first electronic control switch K3 is connected to the VCC power supply provided by the battery module as the first power input terminal, pin 8 of the first electronic control switch K3 is connected to the node Relay as the second power input terminal, and pin 6 of the third electronic control switch K2 as the fifth switch terminal is connected to the node Relay. In this way, pin 8 of the first electronic control switch K3 is connected to pin 6 of the third electronic control switch K2, and pin 5 of the third electronic control switch K2 is used as the third normally open contact for grounding.

[0066] In addition, in this embodiment, the first power input terminal of the first electronic control switch K3 is connected to the cathode of the diode D60, and the second power input terminal of the first electronic control switch K3 is connected to the anode of the diode D60. By setting the diode D60, the current output by the battery module to the first electronic control switch K3 can be made to conduct unidirectionally.

[0067] To achieve unidirectional conduction, in one embodiment, a first diode is further included, and the first diode is connected in series between the first normally closed contact of the first electronic control switch K3 and the trigger switch S1; in one embodiment, the first diode is connected in series between the trigger switch S1 and the second normally closed contact of the first electronic control switch K3.

[0068] In this embodiment, the first diode is used to achieve unidirectional conduction between the first normally closed contact and the second normally closed contact of the first electronic control switch K3. The first diode can be connected in series between the first normally closed contact of the first electronic control switch K3 and the trigger switch S1, or can be connected in series between the trigger switch S1 and the second normally closed contact of the first electronic control switch K3. By setting the first diode, the current is output from the first enable terminal of the battery module, and sequentially passes through the first switch terminal of the first electronic control switch K3, the first normally closed contact of the first electronic control switch K3, the trigger switch S1, the second normally closed contact of the first electronic control switch K3, and the second switch terminal of the first electronic control switch K3, and is output to the second enable terminal of the battery module, realizing unidirectional conduction of the current between the first enable terminal and the second enable terminal of the battery module.

[0069] In one embodiment, the first diode includes diode D59. The first normally closed contact of the first electronic control switch K3 is connected to the positive electrode of the diode D59, and the negative electrode of the diode D59 is connected to the first end of the trigger switch S1.

[0070] In this embodiment, the diode D59 not only realizes the unidirectional conduction of current between the first enable terminal and the second enable terminal of the battery module. Since the diode D59 is connected to the first end of the trigger switch S1 and the pin 6 of the second electronic control switch K4, the diode D59 can also prevent the current of the second power supply from flowing to the first enable terminal of the battery module.

[0071] In one embodiment, the first diode further includes diode D62. The second end of the trigger switch S1 is connected to the anode of the diode D62, and the cathode of the diode D62 is connected to the second normally closed contact of the first electronic control switch K3. In this embodiment, the unidirectional conduction function of the diode D62 enables the unidirectional conduction of current between the first enable terminal and the second enable terminal of the battery module.

[0072] In one embodiment, as Figure 4 shown, a power supply control circuit is provided, including a battery module and the wake-up detection circuit described in any of the above embodiments; the battery module is configured to start when the first enable terminal and the second enable terminal are conducting, and output electrical energy through the electrical energy output terminal.

[0073] In this embodiment, Figure 4 the battery power supply in is the battery module. Please also refer to Figure 1 and Figure 2 . When the first enable terminal and the second enable terminal are not conducting, the battery module is in a sleep state (low power consumption mode). When the first enable terminal and the second enable terminal are conducting, the battery module is woken up and started. After the battery is started, the battery module outputs electrical energy through the electrical energy output terminal. For example, it supplies power to the electrical energy input terminals of the first electronic control switch K3, the second electronic control switch K4, and the third electronic control switch K2, so that the coils of the first electronic control switch K3, the second electronic control switch K4, and the third electronic control switch K2 are energized, and the switch terminals of the first electronic control switch K3, the second electronic control switch K4, and the third electronic control switch K2 are attracted.

[0074] In one embodiment, please refer to again Figure 4, the power supply control circuit further includes a switching power supply and a main control module, the main control module is respectively connected to the switching power supply and the battery module; the switching power supply and the battery module are respectively used for outputting electric energy to the load; the main control module is configured to detect the state of the electric energy output by the switching power supply to the load, and when the switching power supply stops outputting electric energy to the load, control the battery module to enter the low power consumption mode; the battery module is configured to stop outputting electric energy when entering the low power consumption mode.

[0075] In this embodiment, Figure 4 , the main control system is the main control module, and the load can be a motor or other electrical equipment. For example, the load is an electric control wheel or an assist system in a medical system. During normal operation, the switching power supply and the battery module supply power to the load at the same time. When the switching power supply stops outputting electric energy to the load, the control module controls the battery module to enter the low power consumption mode, and the battery module stops supplying power to the power input ends of the first electric control switch K3, the second electric control switch K4, and the third electric control switch K2. The switch ends of the first electric control switch K3, the second electric control switch K4, and the third electric control switch K2 are reset to the normally closed contacts, and the path between the first enable end and the second enable end of the battery module is disconnected. Thus, the battery module and the main control module respectively enter the sleep mode (low power consumption mode).

[0076] In this embodiment, the output end of the opto-isolator is connected to the power input end of the main control module, and the power input end of the main control module is also connected to the power supply DVCC. The output end of the opto-isolator inputs a signal to the power input end of the main control module, making the power input end of the main control module conduct with the power supply DVCC, and the main control module is powered on.

[0077] In one embodiment, please refer to again Figure 4 , a medical system is provided, including the wake-up detection circuit described in any of the above embodiments.

[0078] In this embodiment, the medical system includes an electric control wheel, a drive circuit, and an assist system. The main control module is connected to the drive circuit, and the drive circuit is connected to the assist system. In addition, the main control module is also connected to the electric control wheel. When the battery module wakes up, the third switch end of the second electric control switch K4 is connected to the first normally open contact, so that the second power supply supplies power to the opto-isolator, and then the main control module is woken up. The main control module sends an unlocking signal to the electric control wheel to control the unlocking of the electric control wheel, and the main control module controls the drive circuit to send a signal to the assist system to start the assist system.

[0079] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0080] The embodiments described above merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several variations and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
