Fig. 1 is a schematic structural diagram of a first embodiment of a robot key control system according to an embodiment of the present invention, where, as shown in fig. 1, the system may include: the system comprises a first power supply 11, a first switch circuit 12, a second power supply 13, a key 14, an identity data collector 15 and a microcontroller 16.
The connection relation of the parts is as follows: the first switch circuit 12 includes an input terminal A1, a control terminal A2, and an output terminal A3. The input end A1 of the first switch circuit 12 is connected with the first power supply 11, the output end A3 of the first switch circuit 12 is connected with the second power supply 13, the second power supply 13 is connected with the host circuit 10, and the control end A2 of the first switch circuit 12 is connected with the identity data collector 15 and the first output end OUT1 of the microcontroller 16 respectively. The key 14 is connected to a first input IN1 of the microcontroller 16 and the identity data collector 15 is connected to a second input IN2 of the microcontroller 16.
Note that, the host circuit 10 is not a robot key control system, and therefore, in the present embodiment and the schematic diagrams corresponding to the embodiments described below, the schematic diagrams are indicated by dashed boxes.
The user may press a button 14 arranged on the robot when it is desired to switch the working state of the robot, optionally this button 14 is typically a physical button. Based on the specific connection between the above parts, the key 14 outputs a key trigger signal to the microcontroller 16 after being pressed by the user. The microcontroller 16 receives the key trigger signal and outputs a turn-on control signal to the control terminal A2 of the first switch circuit 12 according to the key trigger signal and the current working state of the robot, so as to turn on the first switch circuit 12.
The specific process of outputting the conduction control signal may be: the microcontroller 16 first receives the key trigger signal output by the key 14 and then determines the current operating state of the robot. If it is determined that the robot is currently in the first operating state, at this time, the first switch circuit 12 is already in the on state, the microcontroller 16 may output the on control signal, but the on control signal does not play any substantial role in the on of the first switch circuit 12. If it is determined that the robot is currently in the second working state, at this time, the first switch circuit 12 is in the non-conducting state, the microcontroller 16 outputs a conducting control signal to the control terminal A2 of the first switch circuit 12, so as to conduct the first switch circuit 12. Wherein, optionally, the first working state may be a power-on state of the robot, and the second working state may be a power-off state of the robot.
After the first switch circuit 12 is turned on, the first power supply 11 may supply power to the identity data collector 15 through the turned-on first switch circuit 12. The identity data collector 15 may collect user identity data of the user itself who presses the key 14 and send the collected user identity data to the microcontroller 16. The microcontroller 16 compares the acquired user identity data with the pre-stored reference identity data, generates a control signal according to the comparison result, and further controls the host circuit 10 of the robot according to the control signal, and makes the robot in different working states by running different functional modules in the host circuit. The reference identity data can be automatically input by a user after the robot is purchased.
Since the action of the user pressing the key is instantaneous, the on control signal output by the microcontroller 16 is also an instantaneous signal, and the conduction of the first switching circuit 12 is also instantaneous. This makes it impossible for the second power supply 13 to continuously output the power supply signal, and at this time, it can be considered that both the second power supply 13 and the host circuit 10 are disconnected. That is, when the user presses a key and the robot is currently in a power-off state, only the key control system of the robot is powered inside the robot, and the remaining circuits are disconnected, so that the effect of reducing the power consumption of the robot can be achieved.
For the first switching circuit 12, it may alternatively be any switching device, such as a MOS transistor, an insulated Gate bipolar transistor (Insulated Gate Bipolar Transistor, abbreviated as IGBT), a Gate Turn-Off Thyristor (abbreviated as GTO), or the like. In practical applications, the first switch circuit 12 may be a MOS transistor, and for distinguishing from subsequent devices, the MOS transistor may be referred to as a first MOS transistor. Alternatively, the MOS transistor model may be FDMA530OZ. The input end A1 of the first switch circuit 12 is the source of the first MOS transistor, the control end A2 of the first switch circuit 12 is the gate of the first MOS transistor, and the output end A3 of the first switch circuit 12 is the drain of the first MOS transistor.
Alternatively, for the key 14 and the identity data collector 15, in practical application, they may be two separate components or may be integrated into the same component. Meanwhile, optionally, the collected user identity data may be fingerprint data or sound data of the user, and the like. In contrast, the identity data collector 15 may be a fingerprint recognition sensor or a voice recognition device or the like.
In this embodiment, the robot key control system includes: the system comprises a first power supply 11, a first switch circuit 12, a second power supply 13, a key 14, an identity data collector 15 and a microcontroller 16. In combination with the specific connection relationship between the above parts, the key 14 outputs a key trigger signal to the microcontroller 16 after being pressed, and the microcontroller 16 outputs a conduction control signal to the control terminal A2 of the first switch circuit 12 according to the key trigger signal and the current working state of the robot, so as to conduct the first switch circuit 12. When the first switch circuit 1 is turned on, the first power supply 11 supplies power to the identity data collector 15, and at this time, the identity data collector 15 collects the user identity data and sends the user identity data to the microcontroller 16. As can be seen from the above description, the identity data collector 15 will only start to operate after the first switch circuit 12 is turned on, and only the key control system of the robot is powered, so that the power consumption of the robot can be greatly reduced. Then, the microcontroller 16 compares the collected user identity data with the pre-stored reference identity data, generates a control signal according to the comparison result, and further controls a host circuit of the robot according to the control signal so as to enable the robot to be in different working states. The system can achieve the purpose of switching the working state of the robot by only allowing the authorized user, namely the user identity data comparison passing user, thereby avoiding misoperation of the robot by a non-authorized user and improving the service quality of the robot.
As can be seen from the description of the first embodiment, the working states of the robot may include the on-state and the off-state of the robot. In order to enable the robot to be in a normal and continuous power-on state, fig. 2 is a schematic structural diagram of a second embodiment of a robot key control system according to an embodiment of the present invention, as shown in fig. 2, the system may further include: a second switching circuit 21.
The second switch circuit 21 includes an input terminal B1, a control terminal B2, and an output terminal B3, the output terminal B3 of the second switch circuit 21 is connected to the control terminal A2 of the first switch circuit 12, the input terminal B1 of the second switch circuit 21 is grounded, and the control terminal B2 of the second switch circuit 21 is connected to the second output terminal OUT2 of the microcontroller 16.
The microcontroller 16 can compare the user identity data acquired by the identity data acquirer 15 with the pre-stored reference identity data, generate an on-off control signal according to the comparison result, and control the on-off of the second switch circuit 21 according to the on-off control signal so as to enable the robot to be in a power-on or power-off state.
Specifically, when the robot is currently in the shutdown state, if the comparison result is that the robot passes, the microcontroller controls the second switch circuit 21 to be turned on according to the generated on-off control signal. Then, the on-off control signal continues to control the first switch circuit 12 to be turned on via the turned-on second switch circuit 21. At this time, the power supply signal output by the first power supply 11 may be input to the second power supply 13 via the turned-on first switch circuit 12, so that the second power supply 13 supplies power to the host circuit 10, and the robot is switched from the off state to the on state. And the microcontroller 16 continuously outputs the on-off control signal, so that the robot can be continuously in a starting state. If the comparison result is that the robot does not pass, the robot is in a shutdown state.
When the robot is in the current starting state, if the comparison result is passing, the microcontroller controls the second switch circuit 21 to be disconnected according to the generated on-off control signal. At this time, the on-off control signal cannot be output from the second switch circuit 21 in the off state to the first switch circuit 12, that is, the first switch circuit 12 is also in the off state. And the disconnection of the first switch circuit 12 further causes the second power supply 13 to fail to supply power to the host circuit 10, and the robot is switched from the on state to the off state. If the comparison result is that the robot does not pass, the robot is still in a starting state.
According to the above description, only the user having the right as the passing user identity data comparison result can switch the working state of the robot by pressing the key 14, while other users cannot change the working state of the robot even pressing the key, that is, the misoperation of the non-right user is avoided.
Alternatively, the on-off control signal may be a high level signal or a low level signal. When the on-off control signal is at a high level, the second switch circuit 21 is turned on. When the on-off control signal is at a low level, the second switch circuit 21 is turned off.
Similar to the first switching circuit 12, the second switching circuit 12 may alternatively be any switching device, such as a MOS transistor, an IGBT, a GTO, or the like. In practical applications, the second switch circuit 12 may also be a MOS transistor, i.e. a second MOS transistor. The second MOS transistor model can be 2SK3018. The input end B1 of the second switch circuit 21 is a source electrode of the second MOS transistor, the control end B2 of the second switch circuit 21 is a gate electrode of the second MOS transistor, and the output end B3 of the second switch circuit 21 is a drain electrode of the second MOS transistor.
In order to accurately switch the working state of the whole robot, all parts in the robot key control system are required to work normally. Thus, optionally, to ensure proper operation of the first switch circuit 12, the robotic key control system further comprises: a first bias circuit 22 consisting of a first bias resistor 221 and a second bias resistor 222.
The first end A1 of the first bias resistor 221 is connected to the input end A1 of the first switch circuit 12, the first end A2 of the second bias resistor 222 is connected to the second end B1 of the first bias resistor 221 and the control end A2 of the first switch circuit 12, and the second end B2 of the second bias resistor 222 is connected to the output end B3 of the second switch circuit 21 and the identity data collector 15.
The first bias circuit 22, which is composed of the first bias resistor 221 and the second bias resistor 222, can be used to adjust the voltage amplitude outputted by the first power supply 11, so that the adjusted voltage amplitude meets the input requirement of the first switch circuit.
Optionally, to ensure that the host circuit 10 in the robot can work properly, the robot key control system further includes: soft start capacitor 23.
The first terminal a3 of the soft start capacitor 23 is connected to the input terminal A1 of the first switching circuit 12, and the second terminal b3 of the current protection capacitor 23 is connected to the control terminal A2 of the first switching circuit 12.
The soft start capacitor 23 can be used for adjusting the current value of the power supply signal output by the first power supply 11 and input to the host circuit 10 through the first switch circuit 21 and the second power supply 13, so as to prolong the on time of the first switch circuit 12, thereby meeting the requirement of soft start. That is, the use of the soft start capacitor 23 can make the current value of the power supply signal input into the host circuit 10 gradually become larger, so as to avoid the situation that the robot starts to over-current trip.
Optionally, in order to ensure the normal operation of the second switch circuit, the robot key control system further includes: a second bias circuit 24 consisting of a third bias resistor 241 and a fourth bias resistor 242.
The first end a4 of the third bias resistor 241 is connected to the control end B2 of the second switch circuit 21, and the second end B4 of the third bias resistor 241 is connected to the second output end OTU2 of the microcontroller 16.
The first terminal a5 of the fourth bias resistor 242 is connected to the input terminal B1 of the second switching circuit 21, and the second terminal B5 of the fourth bias resistor 242 is connected to the first terminal a4 of the third bias resistor 241.
The second bias circuit 24, which is composed of the third bias resistor 241 and the fourth bias resistor 242, can be used to adjust the voltage amplitude of the on-off control signal, so that the adjusted voltage amplitude meets the input requirement of the second switch circuit 21.
In this embodiment, on the basis of the first embodiment, the robot key control system further includes a second switch circuit 21, a first bias circuit 22 composed of a first bias resistor 221 and a second bias resistor 222, an overcurrent protection capacitor 23, and a second bias circuit 24 composed of a third bias resistor 241 and a fourth bias resistor 242. The use of the elements can ensure that the robot key control system can normally compare the user identity data, and further ensure that the robot can normally switch the working state after the user identity data is compared.
In practical applications, the first power supply 11 and the second power supply 13 may have the same power supply voltage, such as 22V. While the input voltage of each part in the robot key control system may be different from the voltages provided by the two power supplies, fig. 3 is a schematic structural diagram of a third embodiment of the robot key control system according to the embodiment of the present invention, as shown in fig. 3, and on the basis of the first embodiment, the system may further include: a voltage conversion circuit 31.
The first terminal a6 of the voltage conversion circuit 31 is connected to the output terminal A3 of the first switch circuit 12, and the second terminal b6 of the voltage conversion circuit 31 is connected to the second power supply 13.
The voltage conversion circuit 31 may be configured to convert a voltage amplitude of a power supply signal output by the first power supply 11 when the first switch circuit 12 is in a conducting state, so that the converted voltage amplitude meets an input requirement of the identity data collector 15.
Optionally, to ensure the normal operation of the identity data collector 15, the robot key control system further comprises: pull-up resistor 321 and diode 322.
The first terminal a7 of the pull-up resistor 321 is connected to the second terminal b6 of the voltage conversion circuit 31, the second terminal b7 of the pull-up resistor 321 is connected to the anode a of the diode 322, the cathode K of the diode 322 is connected to the identity collector 15, and the cathode K of the diode 322 is also connected to the input IN1 of the microcontroller 16 (not shown IN fig. 3).
The pull-up resistor 321 and the diode 322 are used for setting a default value of the I/O interface of the microcontroller 16 itself, that is, initializing the microcontroller 16. When the first power supply 11 outputs a power supply signal, the pull-up resistor 321 and the diode 322 are further used for adjusting the voltage amplitude of the power supply signal, so that the adjusted voltage amplitude meets the input requirement of the identity data collector 15.
In this embodiment, the robot key control system further includes a voltage conversion circuit 31, a pull-up resistor 321, and a diode 322. The use of the elements can ensure that the robot key control system can normally compare user identity data, and lay a foundation for the robot to normally switch working states.
It should be noted that the voltage conversion circuit 31, the pull-up resistor 321 and the diode 322 provided in the third embodiment can be applied to the second embodiment as shown in fig. 2.
It should be noted that fig. 4 is a practical circuit diagram of the robot key control system. The voltage conversion circuit 31 of the microcontroller 16 in the robot key control system provided in the above embodiments is not shown in fig. 4.

P22v_sys_in is the first power supply 11, and p22v_sys_out is the second power supply 13. The p3v3_ldo is obtained by performing voltage conversion processing on the p22v_sys_out, and the p3v3_ldo can also be understood as a power supply for supplying power to the identity data collector 15. Q4 is a first MOS tube, and Q9 is a second MOS tube. R47 is a first bias resistor 221 and R48 is a second bias resistor 222. C43 is the overcurrent protection capacitor 23. R52 is a third bias resistor 241 and R46 is a fourth bias resistor 242. R6 is a pull-up resistor 321 and D6 is a diode 322.
Fig. 5 is a schematic diagram of an internal structure of a robot according to an embodiment of the present invention. As shown in fig. 5, the robot 4 includes: robot key control system 41 and host circuit 42. The schematic structure of the robot key control system 41 is shown in fig. 1 to 3. The host circuit 42 is the host circuit 10 shown in fig. 1 to 3.
The operation of the robot key control system 41 in this embodiment may be described in the embodiments shown in fig. 1 to 3, and will not be described herein.
The following describes how a robot having the above-described robot key control system can avoid misoperation of unauthorized users, taking several specific usage scenarios as examples.
In a scene, robots are generally installed in public service places such as hospitals, museums, or malls. The robot can provide services such as self-help registration, self-help payment, market navigation and the like for the user. In such a complex environment of personnel, it is inevitable that a non-authorized user touches the robot at will, especially when a child presses a button configured by the robot at will for curiosity. After the child presses the key, the robot key control system in the robot collects user identity data of the child and compares the user identity data with the pre-stored reference identity data. Because the prestored reference identity data is usually a worker in a public service place, the comparison result of the user identity data of the child is that the comparison result is not passed, the working state of the robot is not changed after the child presses a key, and misoperation of the child, namely a non-authority person, on the robot is avoided under the condition that the isolation of the robot and the child is not required to be set, so that the service quality of the robot is improved.
In another scenario, robots are often installed in places such as banks where security is involved. Robots may provide users with deposit and withdrawal or other types of financial services while also monitoring the environment within the venue. When an illegal user touches a key configured by the robot, a robot key control system in the robot collects user identity data of the illegal user and compares the user identity data with reference identity data. The prestored reference identity data is usually a bank staff, so that the comparison result of the user identity data of the illegal user is that the comparison result is not passed, the working state of the robot is not changed after the illegal user presses a key, and the misoperation of the illegal user, namely, the illegal staff, on the robot is avoided under the condition that the isolation of the robot is not required, and the service quality of the robot is improved.
