Detailed Description

To facilitate an understanding of the invention, the invention will now be described more fully hereinafter with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

When a high-power controller is controlled by a strong-current switch to realize power-on and power-off, the time from the power-off switch to the MCU on the controller to completely power off usually needs several seconds, and data detected by the MCU are all in an unstable state in the process. If the switch is closed before the MCU is not completely powered down, the MCU will continue to operate, and unreasonable protection phenomena may be triggered due to sudden increase of current or voltage in the circuit, so that the problems of shaking or strong noise and the like of the electric tool occur, and the use experience of a user is influenced. The switch action detection circuit provided by the disclosure can detect the action of the strong current switch in real time, so that the controller can further judge according to the switch action.

Fig. 1 is a schematic structural diagram of a switching operation detection circuit according to one embodiment of the disclosure, in which the switching operation detection circuit may include a switch module 100, a power module 200, and a control module 300.

The switch module 100 may be a single-pole double-throw switch, i.e., the switch may be flipped to both sides to perform a double control function. The switch module 100 may include a first moving terminal 1, a common terminal 2, and a second moving terminal 3. The positive pole of the power module 200 is connected to the first moving terminal 1, the negative pole of the power module 200 is connected to the negative pole of the control module 300, and the positive pole of the control module 300 is connected to the common terminal 2. That is, the power module 200 may be connected to the control module 300 through the switch module 100, and the switch module 100 may change on or off between the switch module 100 and the control module 300 by changing on/off between the first movable terminal 1 and the common terminal 2.

The control module 300 may include a switch detection circuit 310, a voltage detection circuit 320, and a main control unit 330. The switch detection circuit 310 may be connected to the second moving terminal 3 and the main control unit 330, respectively, and the voltage detection circuit 320 may be connected to the common terminal 2 and the main control unit 330, respectively. The main control unit 330 may be an MCU. The voltage detection circuit 320 may be used to detect a first electrical signal at the common terminal 2 and the switch detection circuit 310 may be used to detect a second electrical signal at the second movable terminal. The main control unit 330 may determine the switching action of the switch module 100 according to the first electrical signal detected by the voltage detection circuit 320 and/or the second electrical signal detected by the switch detection circuit 310.

In this embodiment, the first moving terminal 1 can be a normally open terminal, and the second moving terminal 3 can be a normally closed terminal, that is, the switch module 100 is usually in a state where the second moving terminal 3 is conducted with the common terminal 2. Therefore, in the present embodiment, it is defined that the switch module 100 is in the closed state when the first moving terminal 1 is conducted with the common terminal 2, and the switch module 100 is in the open state when the second moving terminal 3 is conducted with the common terminal 2.

When the switch is turned to the first moving terminal 1, the first moving terminal 1 is connected to the common terminal 2, so that the power module 200 can provide power to the control module 300, and the control module 300 is powered on. At this time, the voltage detection circuit 320 may detect that the voltage at the common terminal 2 is large, i.e., the first electrical signal is at a high level. Meanwhile, since the switch is toggled to the first moving terminal 1, the second moving terminal 3 is in an open circuit, and the switch detection circuit 310 will detect that the voltage at the second moving terminal is 0, i.e. the second electrical signal is at a low level. The main control unit 330 may determine that the power module 200 is conducted with the control module 300, that is, the switch module 100 is in a closed state, by combining the information that the first electrical signal is at a high level and the second electrical signal is at a low level.

When the switch is switched from the first moving terminal 1 to the second moving terminal 3, the second moving terminal 1 is connected to the common terminal 2, so that the connection between the power module 200 and the control module 300 is disconnected, and the control module 300 is powered off. However, since it takes several seconds to turn off the switch until the main control module 310 in the control module 300 is completely powered down, the residual power in the control module 300 is transmitted to the second moving terminal 3, so that the switch detection circuit 310 can detect that the voltage at the second moving terminal 3 is large, i.e. the second electrical signal is at a high level. Therefore, the main control unit 330 may determine that the second movable terminal 3 is connected to the common terminal 2, that is, the switch module 100 is in the off state, according to the information that the second electrical signal is at the high level.

If the switch is closed immediately after being opened, that is, the switch is immediately pulled back to the first moving end 1 after being pulled from the first moving end 1 to the second moving end 3, the control module 300 may also determine all actions of the switch according to the change of the first electrical signal and/or the second electrical signal. Therefore, the switch action detection circuit can ensure that the control module 300 can identify all relevant actions of the switch module 100 when the complete machine frequently opens and closes the switch module 100, so as to judge the validity of the currently acquired data according to the switch action.

In the switching action detection circuit, the switching module 100 may be used to turn on or off a connection path between the power module 200 and the control module 300, so as to change the on/off state of the control module 300. The control module 300 detects a first electrical signal at the common terminal and a second electrical signal at the second active terminal of the switch module 100 by using the voltage detection circuit 320 and the switch detection circuit 310, respectively, so that the main control unit 330 can determine the switching action of the switch module 100 according to the first electrical signal and/or the second electrical signal. The switch action detection circuit is used for detecting the action of the switch module in real time, so that the running stability of the control module 300 can be ensured, and the safety of the control module 300 can be improved. The switch action detection circuit has the advantages that the overall performance is improved through less design cost, and the market competitiveness of the product is effectively improved.

Fig. 2 is a schematic structural diagram of a switch detection circuit in one embodiment of the present disclosure, and in one embodiment, the switch detection circuit 310 may include a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a fifth resistor R5, a zener diode D1, a first capacitor C1, and a first field effect transistor Q1. According to the practical application requirements of the switching action detection circuit in different application scenes, appropriate device parameters can be selected for the first resistor R1, the second resistor R2, the third resistor R3, the fourth resistor R4, the fifth resistor R5, the voltage stabilizing diode D1, the first capacitor C1 and the first field effect transistor Q1.

In the present embodiment, the first field effect transistor Q1 is an N-channel enhancement MOSFET. The embodiment can meet the circuit requirement of low power consumption under various wiring modes by using the N-channel enhancement type MOSFET as isolation. For example, when the common terminal 2 is connected to the positive electrode of the power supply, the second moving terminal 3 is connected to the switch detection circuit 310, and the first moving terminal 1 is connected to the controller, the first fet Q1 can still meet the low power consumption requirement of the circuit.

Referring to fig. 2, a first end of the first resistor R1 is connected to the second moving end SWITCH _ NC, a second end of the first resistor R1 is connected to a drain of the first field-effect transistor Q1, a gate of the first field-effect transistor Q1 is respectively connected to a first end of the fourth resistor R4, a first end of the fifth resistor R5, and an anode of the zener diode D1, and a source of the first field-effect transistor Q1 is respectively connected to a first end of the second resistor R2 and a first end of the third resistor R3.

The third resistor R3 and the fourth resistor R4 may serve as a pull-down resistor of the first field effect transistor Q1. When the power is off, if the first field effect transistor Q1 is in the on state, the parasitic capacitance between the gate and the source has no discharge path, which easily causes the breakdown of the first field effect transistor Q1. The third resistor R3 and the fourth resistor R4 can provide a discharge path to prevent the MOS tube from generating misoperation, thereby playing a role in protecting the first field effect tube Q1.

The zener diode D1 can also be used to keep the voltage between the gate and the source stable, and when the voltage VGS between the gate and the source fluctuates, the zener diode D1 can be used to limit the gate voltage of the first field effect transistor Q1 below the regulated value, so as to protect the first field effect transistor Q1 from being broken down by high current.

A second end of the fifth resistor R5 is connected to the power supply VCC, and the fifth resistor R5 may be used as a pull-up resistor of the gate of the first fet Q1. When the power is on, the pull-up resistor can give a certain level to the gate of the first field-effect tube Q1, so that the gate level of the first field-effect tube Q1 is prevented from being uncertain and interfered when the General-purpose input/output (GPIO) is in a high-resistance state when the power is on. A second end of the second resistor R2 is connected to the first end of the first capacitor C1 and the main control unit 330, respectively. When the main control unit 330 is an MCU, the second end of the second resistor R2 and the first end of the first capacitor C1 may be connected to the MCU _ AD pin. The second end of the first capacitor C1, the second end of the third resistor R3, the second end of the fourth resistor R4 and the cathode of the zener diode D1 are all grounded.

When the SWITCH module 100 is closed, the SWITCH is turned to the first moving terminal 1, the first moving terminal 1 is connected to the common terminal 2, and since the second moving terminal 3 is in the off state at this time, the voltage at the SWITCH _ NC is 0V, the gate-source voltage VGS =0 at this time, and the first field effect transistor Q1 is in the off state, so that the voltage at the MCU _ AD is also 0V. It can be seen that the second electrical signal detected by the switch detection circuit 310 at the second moving end 3 is low. Meanwhile, since the first active terminal 1 is connected to the common terminal 2 and is turned on, and the control module 300 is powered on, the voltage detected by the voltage detection circuit 320 connected to the common terminal 2 is at a high level, that is, the first electrical signal is at a high level. The main control unit 330 can determine that the switch module 100 is in the closed state at this time by combining the first electrical signal detected by the voltage detection circuit 320 and the second electrical signal detected by the switch detection circuit 310.

At the moment when the switch module 100 is switched from the on state to the off state, that is, when the switch is switched from the first moving terminal 1 to the second moving terminal 3, and the second moving terminal 3 is connected to the common terminal 2, because the residual electric quantity exists in the control module 300, the electricity emitted by the control module 300 is transmitted to the second moving terminal 3 through the common terminal 2. That is, the voltage at SWITCH _ NC is the same as the voltage at the positive pole of the control module 300. At this time, the gate-source voltage VGS is greater than 0, and when VGS is greater than the turn-on voltage, the first field effect transistor Q1 is turned on, so that the voltage at the MCU _ AD is a high level signal. That is, when the switch is turned off, the second electric signal detected by the switch detection circuit 310 at the second moving terminal 3 is at a high level. The main control unit 330 can determine that the switch is in the off state at this time according to the high level signal at the MCU _ AD at this time.

Even if the switch is closed immediately after being turned off, that is, the voltage at the mcu \ ad position immediately after the switch is shifted from the first moving terminal 1 to the second moving terminal 3 changes from a high level signal to a low level signal, the main control unit 330 can determine that the switch module 100 is frequently turned on or off according to the change of the first electrical signal and/or the second electrical signal. Further, the control module 300 may execute different commands according to the detected switching actions to ensure the stability and safety of the control module 300.

In one embodiment, the power module 200 is a dc power source outputting a predetermined electrical signal. In this embodiment, the preset electrical signal may be an electrical signal with high power, high current, and low frequency, that is, the power module 200 is a direct current strong power supply. The switching operation detection circuit is suitable for a direct current strong current circuit.

Based on the above description of the embodiment of the switching action detection circuit, the invention also provides a switching action detection method. The switching operation detection circuit may include a device (including a distributed system), software (application), a module, a component, a server, a client, and the like, which uses the switching operation detection method according to the embodiment of the present specification, and a device that incorporates necessary hardware for implementation. Based on the same innovative concept, embodiments of the present invention provide methods in one or more embodiments as described in the following embodiments. Since the implementation scheme of the method for solving the problem is similar to that of the apparatus, the specific apparatus implementation in the embodiment of the present description may refer to the implementation of the foregoing apparatus, and repeated details are not repeated. As used hereinafter, the term "unit" or "module" may be a combination of software and/or hardware that implements a predetermined function. The means described in the above embodiments may be implemented in software or hardware, or a combination of software and hardware.

Fig. 3 is a schematic flow chart of a method for detecting a switch according to one embodiment of the present disclosure, in which the method for detecting a switch can be applied to a circuit for detecting a switching operation according to any one of the above embodiments, and the method includes the following steps S100 to S200.

Step S100: a first electrical signal at a common terminal and a second electrical signal at a second moving terminal are acquired.

The switching action detection circuit may include a switching module 100, a power module 200, and a control module 300. The control module 300 may include a switch detection circuit 310, a voltage detection circuit 320, and a main control unit 330. The voltage detection circuit 320 may be used to detect a first electrical signal at the common terminal 2 and the switch detection circuit 310 may be used to detect a second electrical signal at the second movable terminal. The voltage detection circuit 320 and the switch detection circuit 310 may transmit the detected first electrical signal and the second electrical signal to the main control unit 330, respectively, in real time.

Step S200: the switching action of the switching module is determined from the first electrical signal and/or the second electrical signal.

The switch module 100 may include a first moving terminal 1, a common terminal 2, and a second moving terminal 3. In this embodiment, the first moving terminal 1 may be a normally open terminal, and the second moving terminal 3 may be a normally closed terminal, that is, the switch module 100 is normally in a state where the second moving terminal 3 is conducted with the common terminal 2. Therefore, in the present embodiment, it is defined that the switch module 100 is in the closed state when the first moving terminal 1 is conducted with the common terminal 2, and the switch module 100 is in the open state when the second moving terminal 3 is conducted with the common terminal 2.

When the switch module 100 is closed, the power module 200 may provide power to the control module 300 and the control module 300 is powered on. At this time, the voltage detection circuit 320 may detect that the first electrical signal at the common terminal 2 is at a high level. Meanwhile, since the switch is toggled to the first moving terminal 1, the second moving terminal 3 is in an open circuit, and the switch detection circuit 310 will detect that the second electrical signal at the second moving terminal 3 is at a low level. The main control unit 330 may determine that the power module 200 is conducted with the control module 300, that is, the switch module 100 is in the closed state, according to the information that the first electrical signal is at the high level and the second electrical signal is at the low level.

When the switch module 100 is turned off, the connection path between the power module 200 and the control module 300 is disconnected, and the control module 300 is powered off. However, since it takes several seconds to completely power down the main control module 330 in the control module 300 by opening the switch, the residual power in the control module 300 will be transmitted to the second moving terminal 3, so that the switch detection circuit 310 can detect that the second electric signal at the second moving terminal 3 is at a high level. Therefore, the main control unit 330 may determine that the second movable terminal 3 is connected to the common terminal 2, that is, the switch module 100 is in the off state, according to the information that the second electrical signal is at the high level.

If the switch module 100 is closed immediately after being opened, the control module 300 may also determine all actions of the switch according to the changes of the first electrical signal and/or the second electrical signal. Therefore, the switch action detection circuit can ensure that the control module 300 can identify all relevant actions of the switch module 100 when the complete machine frequently opens and closes the switch module 100, so as to judge the validity of the currently acquired data according to the switch action.

In the above switching operation detection method, by detecting the first electrical signal at the common terminal of the switch module 100 and the second electrical signal at the second active terminal, the switching operation of the switch module 100 can be determined according to the first electrical signal and/or the second electrical signal. By monitoring the operation of the switch module 100 in real time, the operation stability of the control module 300 can be ensured, and the safety of the control module 300 can be improved. Therefore, the switching action detection method can improve the performance of the whole machine and improve the market competitiveness of the product.

Fig. 4 is a flowchart illustrating a method of a switch detection method according to another embodiment of the disclosure, wherein in one embodiment, determining a switching action of a switch module according to a first electrical signal and/or a second electrical signal may include the following step S210.

Step S210: and when the first electric signal is greater than the first threshold value and the second electric signal is less than or equal to the second threshold value, judging that the switch module is in a closed state.

The second threshold may be a start voltage of the first field effect transistor Q1, and when the second electrical signal at the second moving end 3 is less than or equal to the start voltage of the first field effect transistor Q1, the first field effect transistor Q1 is turned off, so that the voltage at the MCU _ AD is a low level signal. That is, when the switch is closed, the second electric signal detected by the switch detection circuit 310 at the second moving end 3 is a low-level signal equal to or less than the second threshold value. The first threshold may be a value for determining whether the common node 2 is conducted with the power module 200. That is, when the switch is closed, the first electric signal detected at the common terminal 2 by the voltage detection circuit 320 is a high-level signal greater than the first threshold value. The main control unit 330 can determine that the switch module 100 is in the closed state at this time by combining the first electrical signal detected by the voltage detection circuit 320 and the second electrical signal detected by the switch detection circuit 310.

In one embodiment, after determining that the switch module is in the closed state, the method may further include the following step S211.

Step S211: and detecting the states of all the pins and setting the detection judgment time of the related variables.

When the main control unit 330 determines that the switch module 100 is in the closed state at this time by combining the first electrical signal detected by the voltage detection circuit 320 and the second electrical signal detected by the switch detection circuit 310, the MCU may perform operations of re-detecting states of all pins and setting detection determination time of relevant variables, so as to ensure validity of data acquired by the MCU.

In one embodiment, determining the switching action of the switching module according to the first electrical signal and/or the second electrical signal may further include the following step S220.

S220: and when the second electric signal is larger than the second threshold value, the switch module is judged to be in an off state.

When the switch module 100 is turned off, the switch is shifted from the first moving terminal 1 to the second moving terminal 3, and the second moving terminal 3 is connected to the common terminal 2. Since there is a residual amount of power in the control module 300, the power discharged from the control module 300 is transmitted to the second movable terminal 3 through the common terminal 2. That is, the voltage at SWITCH _ NC is the same as the voltage at the positive pole of the control module 300. The second threshold may be a start-up voltage of the first field-effect transistor Q1, and when VGS is greater than the start-up voltage, the first field-effect transistor Q1 is turned on, so that the voltage at the MCU _ AD is a high level signal. That is, when the switch is open, the switch detection circuit 310 detects the second electrical signal greater than the second threshold at the second moving end 3. The main control unit 330 can determine that the switch is in the off state according to the high level signal at the MCU _ AD.

In one embodiment, after determining that the switch module is in the off state, the method may further include the following step S221.

S221: and clearing all the detected related variables.

When the main control unit 330 determines that the switch module 100 is in the off state according to the second electrical signal detected by the switch detection circuit 310, the MCU may zero all the detected relevant variables. The data instability that prevents to detect leads to electric tool to appear the shake or unnecessary problems such as noise intensity, optimizes user's use and experiences.

Since the control module 300 may be in an unstable state when frequently turned on and off, the protection mechanism of the motor circuit may be triggered with a probability in an unnecessary case. By using the switch action detection method, unreasonable variation in software can be cleared through the action of the switch. The MCU clears the relevant variables when detecting the switch-off instant, so that it can be ensured that the re-detected relevant variables are not wrong values when the next fast boot is performed, and the control module 300 can reasonably determine the validity of the collected data.

In one embodiment, before acquiring the first electrical signal at the common end and the second electrical signal at the second movable end, the method may further include setting the detection judgment time of the relevant variable to be greater than a preset threshold value. The preset threshold may be a time required from when the switch is turned off to when the MCU is completely powered off, that is, after the MCU is turned on, the MCU waits for a certain time to perform a data acquisition action, thereby preventing the detected relevant variable from being an unreasonable value. According to the embodiment of the disclosure, by setting the detection judgment time of the MCU related variable to be greater than the preset threshold value and prolonging the detection judgment time of the related parameter to be greater than the power-down time of the control module 300 by using software, the validity of the collected data can be ensured under the condition of not detecting the switch action, so that the operation stability of the control module 300 is improved.

It should be understood that, although the steps in the flowcharts of the figures in the specification are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not limited to being performed in the exact order illustrated and, unless explicitly stated herein, may be performed in other orders.
