[0002] In recent years, with the development of robot technology and the continuous in-depth research on artificial intelligence, intelligent mobile robots have played an increasingly important role in human life and have been widely used in many fields, such as the application of robots autonomously taking elevators to achieve unmanned distribution.

[0003] The process of a robot autonomously taking an elevator requires the coordinated operation of an elevator control system. When the robot issues an instruction according to the guest's needs, it notifies the control device that the robot autonomously takes the elevator to achieve the distribution purpose. The robot's autonomous elevator ride requires a set of intelligent control devices to assist the robot in taking the elevator. The main control unit of this control device is generally installed on the top of the elevator car.

[0025] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to the accompanying 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.

[0026] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0027] It should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present application.

[0028] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality" means two or more unless otherwise specifically defined.

[0029] As Figure 1 shown, in the first aspect of the embodiment of the present application, a reset circuit 10 is provided. The reset circuit 10 is used to be connected to a target circuit 20. Among them, the reset circuit 10 includes a detection circuit 100, a reset control circuit 200, and a key indicator light circuit 300. The key indicator light circuit 300 includes a first key indicator light circuit 310 and a second key indicator light circuit 320. The first key indicator light circuit 310 and the second key indicator light circuit 320 are respectively connected to the detection circuit 100. The detection circuit 100 is used to detect whether the first key indicator light circuit 310 and the second key indicator light circuit 320 are powered on. The detection circuit 100 is used to output a trigger signal when both the first key indicator light circuit 310 and the second key indicator light circuit 320 are powered on and last for a first preset duration. The first preset duration here is, for example, 5 seconds, 10 seconds, 15 seconds, 25 seconds, etc.

[0030] The reset control circuit 200 is connected to the detection circuit 100 and is configured to output a reset signal to the target circuit 20 when receiving the trigger signal from the detection circuit 100, so as to reset and restart the target circuit 20. In one embodiment, the reset signal is, for example, a low-level signal, and the target circuit 20 is, for example, a microprocessor on an electronic device for controlling an elevator, or a microprocessor on a display device, a safety alarm device, or a monitoring device provided on the elevator. The reset signal is output to the reset pin of the microprocessor to achieve the reset and restart of the microprocessor.

[0031] The reset circuit 10 provided in the first aspect of the embodiments of the present application detects whether the first key indicator circuit 310 and the second key indicator circuit 320 of the key indicator circuit 300 are powered on and lit through the detection circuit 100, so as to detect which keys of the elevator are pressed. And when at least two key indicator circuits, namely the first key indicator circuit 310 and the second key indicator circuit 320, are powered on and lit simultaneously and last for a first preset duration, the detection circuit 100 outputs a trigger signal to the reset control circuit 200. After receiving the trigger signal, the reset control circuit 200 outputs a reset signal to the target circuit 20 to achieve the restart of the target circuit 20. By a person operating the keys of the elevator inside the elevator, the restart of the target circuit 20 can be controlled, and it is not necessary for the person to find and operate the target circuit 20 personally to complete its reset and restart, which greatly reduces the labor cost of equipment maintenance.

[0032] Moreover, the elevator is a specialized device. If the target circuit 20 fails and needs to be restarted, maintenance personnel without the qualification for maintaining specialized devices cannot stop the elevator to maintain the target circuit 20. The reset circuit 10 provided in the present application can greatly reduce the maintenance time and labor cost in this situation.

[0033] In one embodiment, referring to Figure 1 , the first key indicator circuit 310 includes a first key indicator LED1, and the second key indicator circuit 320 includes a second key indicator LED2. Among them, the first key indicator LED1 is used to indicate the door opening key of the elevator, and the second key indicator LED2 is used to indicate the door closing key of the elevator. Such a setting can prevent passengers from accidentally touching the keys and causing misdetection by the detection circuit 100. The number and types of other floor keys of the elevator are generally uncertain, which is not conducive to unified management. However, the door opening key and the door closing key are operation keys that all elevators have, and the purposes of these two keys are contrary. Generally, unrelated personnel will not press these two keys simultaneously, which can effectively prevent the reset circuit 10 from being accidentally started.

[0034] In one embodiment, a wireless transmission method may be adopted between the detection circuit 100 and the reset control circuit 200 to transmit the trigger signal. The wireless transmission method may be, for example, Bluetooth, WIFI, 4G, Zigbee, etc. In an actual circuit, the detection circuit 100 and the reset control circuit 200 may be separately installed and set. When our target circuit 20 is not arranged around the elevator car, for example, the detection circuit 100 is arranged inside the elevator car and the target circuit 20 is located on a certain floor where the elevator stops. At this time, the reset control circuit 200 may be arranged on the side of the target circuit 20 to achieve long-distance reset and restart control.

[0035] Please refer to Figure 2 , taking the detection of the power-on states of two key indicators as an example, the detection circuit 100 includes a first detection unit 110, a second detection unit 120, and a control unit 130.

[0036] The first end OKEY+ of the first detection unit 110 is connected to the input end of the first key indicator circuit 310, and the second end OKEY− of the first detection unit 110 is connected to the output end of the first key indicator circuit 310. The first detection unit 110 is configured to output a first level signal to the control unit 130 when the first key indicator circuit 310 is powered on.

[0037] The first end CKEY+ of the second detection unit 120 is connected to the input end of the second key indicator circuit 320, and the second end CKEY− of the second detection unit 120 is connected to the output end of the second key indicator circuit 320. The second detection unit 120 is configured to output a second level signal to the control unit 130 when the second key indicator circuit 320 is powered on.

[0038] The control unit 130 is configured to output a trigger signal with a second preset duration when receiving both the first level signal and the second level signal and lasting for a first preset duration. In one embodiment, the first preset duration is 15 seconds. Setting the first preset duration to 15 seconds can prevent passengers in the elevator from accidentally touching the keys. The control unit 130 receives both the first level signal and the second level signal and maintains for 15 seconds before outputting the trigger signal. In one embodiment, the second preset duration is 200 milliseconds. It can be understood that the trigger signal lasts for 200 milliseconds, so that the low-level reset signal output by the reset circuit 10 also lasts for the same duration, enabling the target circuit 20 to be powered off for a certain duration and then powered on and restarted to complete the reset.

[0039] In some embodiments, the detection circuit 100 may further include a third detection unit, a fourth detection unit, etc. The first detection unit 110 and the second detection unit 120 disclosed in this embodiment only illustrate the case where the detection circuit 100 includes two detection units. It can be understood that when the detection circuit 100 includes a third detection unit, a fourth detection unit, or more detection units, the corresponding key indicator circuit 300 includes a third key indicator circuit, a fourth key indicator circuit, etc.

[0040] Please refer to Figure 3 and Figure 4 , in one embodiment, the first detection unit 110 includes a first switching transistor Q1, a first optocoupler U1, a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, and a fifth resistor R5.

[0041] The first conduction end of the first switching transistor Q1, that is, the second end OKEY- of the first detection unit 110, is used to connect to the output end of the first key indicator circuit 310. The second conduction end of the first switching transistor Q1 is connected to the first input end of the first optocoupler U1. The control end of the first switching transistor Q1 is connected to the input end of the first key indicator circuit 310 through the first resistor R1, that is, connected to the first end OKEY+ of the first detection unit 110. The second input end of the first optocoupler U1 is connected to the input end of the first key indicator circuit 310 through the second resistor R2. The third resistor R3 is connected between the first conduction end and the control end of the first switching transistor Q1. The first output end of the first optocoupler U1 is connected to the voltage source VDD1 through the fourth resistor R4. The second output end of the first optocoupler U1 is grounded through the fifth resistor R5. The second output end of the first optocoupler U1 is used to output a first-level signal at the output end KEY1 of the first detection unit 110. It can be understood that when the first detection unit 110 detects that the first key indicator circuit 310 is powered on, the first-level signal at its output end KEY1 is a high-level signal.

[0042] Among them, the first optocoupler U1 is an optoelectronic coupler. The first input end of the first optocoupler U1 corresponds to the negative electrode of the light-emitting diode of the optoelectronic coupler. The second input end of the first optocoupler U1 corresponds to the positive electrode of the light-emitting diode of the optoelectronic coupler. The first output end of the first optocoupler U1 corresponds to the collector of the phototransistor of the optoelectronic coupler. The second output end of the first optocoupler U1 corresponds to the emitter of the phototransistor of the optoelectronic coupler. The first optocoupler U1 plays an isolation role. The first resistor R1 plays a current-limiting role and is used to limit the current at the control end of the first switching transistor Q1. The second resistor R2 plays a current-limiting role and is used to limit the current at the second input end of the first optocoupler U1. Since the voltage when the first key indicator LED1 is powered on is uncertain, therefore, refer to Figure 3, a resistor R12 and a resistor R13 are further provided. The resistor R12 and the resistor R13 are connected in parallel with the second resistor R2. In an actual circuit, the resistance values of the second resistor R2, the resistor R12, and the resistor R13 can be adjusted according to the voltage when the first key indicator LED1 is energized to meet the power of the resistor itself and the working voltage and current of the first optocoupler U1. The third resistor R3 is used to stabilize the state between the first conduction end and the control end of the first switching transistor Q1 to ensure reliable turn-off when the first switching transistor Q1 is de-energized. The fourth resistor R4 is used to stabilize the voltage state of the first output end of the first optocoupler U1, and the fifth resistor R5 functions as a current limiter.

[0043] Please refer to Figure 3 and Figure 4 , the second detection unit 120 includes a second switching transistor Q2, a second optocoupler U2, a sixth resistor R6, a seventh resistor R7, an eighth resistor R8, a ninth resistor R9, and a tenth resistor R10.

[0044] The first conduction end of the second switching transistor Q2, that is, the second end CKEY− of the second detection unit 120, is used to connect to the output end of the second key indicator circuit 320. The second conduction end of the second switching transistor Q2 is connected to the first input end of the second optocoupler U2. The control end of the second switching transistor Q2 is connected to the input end of the second key indicator circuit 320 through the sixth resistor R6, that is, connected to the first end CKEY+ of the second detection unit 120. The second input end of the second optocoupler U2 is connected to the input end of the second key indicator circuit 320 through the seventh resistor R7. The eighth resistor R8 is connected between the first conduction end and the control end of the second switching transistor Q2. The first output end of the second optocoupler U2 is connected to the voltage source VDD1 through the ninth resistor R9. The second output end of the second optocoupler U2 is grounded through the tenth resistor R10. The second output end of the second optocoupler U2 is used to output a second-level signal at the output end KEY2 of the second detection unit 120. It can be understood that when the second detection unit 120 detects that the second key indicator circuit 320 is energized, the second-level signal at its output end KEY2 is a high-level signal.

[0045] Among them, the second optocoupler U2 is an optoelectronic coupler. The first input end of the second optocoupler U2 corresponds to the negative electrode of the light-emitting diode of the optoelectronic coupler. The second input end of the second optocoupler U2 corresponds to the positive electrode of the light-emitting diode of the optoelectronic coupler. The first output end of the second optocoupler U2 corresponds to the collector of the phototransistor of the optoelectronic coupler. The second output end of the second optocoupler U2 corresponds to the emitter of the phototransistor of the optoelectronic coupler. The second optocoupler U2 functions as an isolation. The sixth resistor R6 functions as a current limiter and is used to limit the current at the control end of the second switching transistor Q2. The seventh resistor R7 functions as a current limiter and is used to limit the current at the second input end of the second optocoupler U2. Since the voltage when the second key indicator LED2 is energized is uncertain, therefore, refer to Figure 3, a resistor R14 and a resistor R15 are further provided. The resistor R14 and the resistor R15 are connected in parallel with the seventh resistor R7. In the actual circuit, the resistance values of the seventh resistor R7, the resistor R14, and the resistor R15 can be adjusted according to the voltage when the second button indicator LED2 is energized, so as to meet the power of the resistor itself and the working voltage and current of the second optocoupler U2. The eighth resistor R8 is used to stabilize the state between the first conduction end and the control end of the second switching transistor Q2, ensuring reliable turn-off when the second switching transistor Q2 is powered off. The ninth resistor R9 is used to stabilize the voltage state of the first output end of the second optocoupler U2, and the tenth resistor R10 functions as a current limiter.

[0046] Please refer to Figure 3 and Figure 4 , the control unit 130 includes a controller MCU. The second output end of the first optocoupler U1, that is, the output end KEY1 of the first detection unit 110, and the second output end of the second optocoupler U2, that is, the output end KEY2 of the second detection unit 120, are respectively connected to the controller MCU. When the controller MCU receives the first level signal and the second level signal and lasts for the first preset duration, the output end MCU_RST of the controller MCU outputs a trigger signal for the second preset duration. In one embodiment, the trigger signal is, for example, a high-level signal, and the second preset duration is, for example, 200 milliseconds.

[0047] In one embodiment, the voltage of the voltage source VDD1 is, for example, 3.3V.

[0048] Please refer to Figure 5 , in one embodiment, the reset control circuit 200 includes a first switch unit 210 and a second switch unit 220. The first end of the first switch unit 210 is grounded, the second end of the first switch unit 210 is connected to the first end of the second switch unit 220, the control end of the first switch unit 210 is connected to the detection circuit 100, the second end of the second switch unit 220 is connected to the voltage stabilizer source VDD2. The first switch unit 210 is used to conduct when receiving the trigger signal to connect the power supply circuit of the second switch unit 220, and the second switch unit 220 is used to output a reset signal to the target circuit 20 when its power supply circuit is connected.

[0049] Please refer to Figure 6, Further, in one embodiment, the reset control circuit 200 further includes a third switch unit 230. The first end of the third switch unit 230 is grounded, the second end of the third switch unit 230 is connected to the first end of the second switch unit 220, and the third switch unit 230 is configured to conduct when receiving a user operation to turn on the power supply loop of the second switch unit 220, so that the second switch unit 220 outputs a reset signal. By setting the third switch unit 230, another solution is provided for the second switch unit 220 to output a reset signal. In addition to turning on the first switch unit 210, the second switch unit 220 can also output a reset signal according to the user operation. Even if the detection circuit 100 has a circuit failure and cannot detect normally, the reset circuit 10 can still output a reset signal through manual operation. Here, the user operation is, for example, a key press action.

[0050] Please refer to Figure 7 , Specifically, in one embodiment, the first switch unit 210 includes a third switching transistor Q3 and an eleventh resistor R11, and the second switch unit 220 includes a relay J1, a first light-emitting diode D1, and a first discharge diode D2.

[0051] The first conducting end of the third switching transistor Q3 is grounded, the second conducting end of the third switching transistor Q3 is connected to the first end of the coil of the relay J1, and the control end of the third switching transistor Q3 is connected to the detection circuit 100 through the eleventh resistor R11. The second end of the coil of the relay J1 is connected to the regulated power supply VDD2, and the switch of the relay J1 is connected in series between the output terminal RST of the second switch unit 220 and the ground. Among them, the eleventh resistor R11 plays a current limiting role. Further refer to Figure 7 , A resistor R16 is also connected between the first conducting end and the control end of the third switching transistor Q3. In the actual circuit, the resistor R16 is a no-connection (NC) resistor. It can be understood that when the trigger signal at the output terminal RST of the second switch unit 220 is a high-level signal, the third switching transistor Q3 conducts, the relay J1 is powered on and works, and the normally closed contact of the relay J1 closes, and a low-level reset signal is output at the output terminal RST of the second switch unit 220.

[0052] In one embodiment, the voltage of the regulated power supply VDD2 is, for example, 5V.

[0053] Please refer to Figure 7 , Specifically, a resistor R18 is connected in series between the switch of the relay J1 and the ground. In the actual circuit, the resistor R18 is a 0Ω resistor. The resistor R18 is for reserving a position to add an electromagnetic compatibility (EMC) radiation reduction device, such as a magnetic bead.

[0054] The first light-emitting diode D1 is connected in parallel with the coil of the relay J1. When the first light-emitting diode D1 lights up, it indicates that the relay J1 is powered on and working. The first discharge diode D2 is connected in parallel with the coil of the relay J1 and is used to provide a reverse electromotive force discharge circuit for the relay J1. It can be understood that the cathode of the first discharge diode D2 is connected to the second end of the coil of the relay J1, and the anode of the first discharge diode D2 is connected to the first end of the coil of the relay J1.

The button K1 is used to connect the power supply circuit of the second switch unit 220 when it is pressed, and the transient suppression diode Z1 is used for debouncing of the button K1 to improve the stability when the button K1 is pressed.

[0056] Please refer to Figure 8 , in one embodiment, Figure 8 The power supply circuit 410 of the target circuit 20 is shown. The power supply circuit 410 receives the reset signal of the reset circuit 10 to reset and restart the target circuit 20. Specifically, the output terminal RST of the reset circuit 10 outputs a low-level reset signal to reset the target circuit 20. For example, two pins of the main control board are short-circuited, that is, pins 1 and 2 of the socket J21 are short-circuited with pins 3 and 4. The socket J21 is connected to the socket X119 through a wire harness. At this time, pins 1 and 2 of the socket X119 are also short-circuited with pins 3 and 4. The switching transistor Q4 is an NMOS transistor, and the switching transistors Q4 and Q5 are cut off, that is, the power supply circuit 410 stops outputting a 12V supply voltage, and the main control board is powered off. Similarly, after the reset circuit 10 stops outputting the reset signal, two pins of the main control board are open-circuited, that is, pins 1 and 2 of the socket J21 are open-circuited with pins 3 and 4. At this time, pins 1 and 2 of the socket X119 are also open-circuited. The voltage output by the power supply enables the switching transistor Q4 to conduct and Q5 to also conduct. The power supply circuit 410 outputs a 12V supply voltage, and the main control board is powered on again to complete the power-off restart reset.

[0057] The reset circuit 10 provided in the first aspect of the embodiment of the present application detects whether the first key indicator circuit 310 and the second key indicator circuit 320 of the key indicator circuit 300 are powered on and lit through the detection circuit 100, so as to detect which keys of the elevator are pressed. And when at least two key indicator circuits, namely the first key indicator circuit 310 and the second key indicator circuit 320, are powered on and lit simultaneously and last for the first preset duration, the detection circuit 100 outputs a trigger signal to the reset control circuit 200. After receiving the trigger signal, the reset control circuit 200 outputs a reset signal to the target circuit 20 to restart the target circuit 20. By operating the keys of the elevator inside the elevator by personnel, the restart of the target circuit 20 can be controlled, and it is not necessary for personnel to find and operate the target circuit 20 personally to complete its reset and restart, which greatly reduces the labor cost of equipment maintenance.
