Detailed implementation manners

[0035] Hereinafter, the exemplary embodiments of the present application will be described in more detail with reference to the drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present application can be more thoroughly understood and the scope of the present application can be fully conveyed to those skilled in the art.

[0036] As Figure 1 shown, the present application provides an electronic device 1, including:

[0037] Control module 11;

[0038] Target module 12, the target module 12 is connected to the control module 11, and the target module 12 has a power supply module 121 and a clearing module 122;

[0039] Based on when the power supply module 121 is powered on, the control signal of the control module 11 controls the target module 12 to be in the first state, and the clearing module 122 is in the non-conductive state;

[0040] Based on when the power supply module 121 is not powered on, the control signal of the control module 11 controls the target module 12 to be in the second state, and the clearing module 122 is in the conductive state for clearing the semiconductor memory information.

[0041] An electronic device 1 provided by an embodiment of the present application includes a control module 11 and a target module 12. The control module 11 is connected to the target module 12. The control module 11 is configured to send a control signal to the target module 12. The target module 12 includes a power supply module 121 and a clearing module 122. When the power supply module 121 is in a powered state, the electronic device 1 can operate normally. The control signal of the control module 11 will control the target module 12 to be in a first state. At this time, the clearing module 122 in the target module 12 is not turned on and will not clear the information in the semiconductor memory. When the power supply module 121 is in an unpowered state, the electronic device 1 does not operate. The control signal of the control module 11 controls the target module 12 to be in a second state. At this time, the clearing module 122 is in a conducting state. The conducting clearing module 122 can be used to clear the information in the semiconductor memory. Thus, when the user's illegal operation causes the electronic device 1 to fail to boot, for the electronic device 1 provided by the present application, the control module 11 only needs to send a control signal to the target module 12, and the target module 12 can be made to be in the second state. At this time, the clearing module 122 in the target module 12 can clear the information in the semiconductor memory. Thus, it is not necessary for a professional after-sales personnel to come to the door to disassemble the machine for data clearing. The user can solve the clearing of the semiconductor memory information by himself. The operation is simple and convenient, without the need for professional personnel to come to the door for operation, reducing the waiting time of the user and lowering the capital cost and time cost.

[0042] As Figure 2 shown, in the embodiment of the present application, the target module 12 further includes a backup power supply module 123, and the backup power supply module 123 is in a powered state;

[0043] Based on when the power supply module 121 is powered, the first state is that the power supply module 121 is electrically connected to the power line, and the backup power supply module 123 and the power supply module 121 are not electrically connected to the clearing module 122 so that the clearing module 122 is in an unturned-on state;

[0044] Based on when the power supply module 121 is unpowered, the second state is that the power supply module 121 is not electrically connected to the power line, and the backup power supply module 123 is electrically connected to the clearing module 122 so that the clearing module 122 is in a conducting state.

[0045] In this embodiment, the target module 12 includes a power supply module 121, a clearing module 122 and a backup power supply module 123, as Figure 5As shown, the backup power supply module 123 is VCCRTC, which is an on-board battery. The backup power supply module 123 is always in a powered state. The power supply module 121 can be in a powered state or an unpowered state. And the power supply module 121 included in the target module 12 does not directly supply power to the electronic device 1. The power supply module 121 is a part of the total power supply device that supplies power to the electronic device 1 and has the same state as the total power supply device. When the total power supply device supplies power to the electronic device 1, the total power supply module 121 is connected to the power line, and the power supply module 121 is also connected to the power line, and the power supply module 121 is in a powered state. When the total power supply device does not supply power to the electronic device 1, the total power supply module 121 is not connected to the power line, and the power supply module 121 is also not connected to the power line, and the power supply module 121 is in an unpowered state. When the power supply module 121 is in a powered state, the control signal of the control module 11 controls the target module 12 to be in the first state. In the first state, the power supply module 121 is connected to the power line. At this time, neither the backup power supply module 123 nor the power supply module 121 is electrically connected to the clearing module 122. Therefore, neither the power supply module 121 nor the backup power supply module 123 supplies power to the clearing module 122, and thus the clearing module 122 is in an unconducted state. When the power supply module 121 is in an unpowered state, the control signal of the control module 11 controls the target module 12 to be in the second state. In the second state, the power supply module 121 is not connected to the power line, but the backup power supply module 123 can be electrically connected to the clearing module 122. Therefore, the clearing module 122 is in a conducted state. The conducted clearing module 122 can be used to clear the semiconductor memory information. Thus, there is no need for professional after-sales personnel to come to the door to disassemble the machine for data clearing. The user can, on his own, make the control module 11 send a control signal to the target module 12 when the power supply module 121 is not powered, so as to solve the problem of clearing the semiconductor memory information. The operation is simple and convenient, without the need for professional personnel to come to the door for operation, reducing the waiting time of the user and lowering the capital cost and time cost.

[0046] As Figure 2 shown, in the embodiment of the present application, the control module 11 includes an output module 111, a rectifier diode module 112, and an input module 113. The input module 113 is connected to the first pin of the rectifier diode module 112. The target module 12 is connected to the second pin of the rectifier diode module 112. The output module 111 is connected to the third pin of the rectifier diode module 112;

[0047] The input module 113 and the output module 111 control the target module 12 to be in the first state or the second state through a control signal, and the control signal is a power supply conduction indication signal.

[0048] In this embodiment, the control module 11 includes an output module 111, a rectifier diode module 112, and an input module 113. As Figure 5 shown, the output module 111 is the main control switch button of the electronic device 1, and the rectifier diode module 112 is Figure 5 D13 in

in Figure 5 shown, the output module 111 is the main control switch button of the electronic device 1, and the rectifierAs shown, in the embodiment of the present application, the target module 12 includes a first switch module 124 and a voltage dividing unit 125. The first end of the first switch module 124 is connected to the second pin. The second end of the first switch module 124 is connected to the backup power supply module 123. The second end of the first switch module 124 is connected to the second pin through the voltage dividing unit 125. The voltage dividing unit 125 is connected to the backup power supply module 123. The third end of the first switch module 124 is respectively connected to the power supply module 121 and the clearing module 122;

[0051] When the control module 11 transmits a control signal to the target module 12, the second end of the first switch module 124 is turned on with the third end of the first switch module 124, and the backup power supply module 123 performs electrical signal transmission through the first switch module 124;

[0052] When the control module 11 does not transmit a control signal to the target module 12, the first switch module 124 is not turned on, and the backup power supply module 123 does not perform electrical signal transmission through the first switch module 124.

[0053] In this embodiment, the target module 12 includes a first switch module 124 and a voltage dividing unit 125, as Figure 5 shown, the first switch module 124 is Figure 5In Q1 of [the description], the first switch module 124 has a first end, a second end, and a third end. The first end of the first switch module 124 is connected to the second pin of the rectifier diode module 112. The second end of the first switch module 124 is connected to the backup power supply module 123. The third end of the first switch module 124 is respectively connected to the power supply module 121 and the clearing module 122. Moreover, the second end of the first switch module 124 is also connected to the second pin of the rectifier diode module 112 through the voltage dividing unit 125, and the voltage dividing unit 125 is also connected to the backup power supply. The second pin of the rectifier diode module 112 is connected to the first pin of the first switch module 124, thereby transmitting the control signal to the first pin of the first switch module 124. When the control module 11 transmits the control signal to the target module 12 through the second pin of the rectifier diode module 112, the backup power supply module 123 transmits the backup voltage to the second end of the first switch module 124. The first end of the first switch module 124 is also connected to the second pin of the rectifier diode module 112 through the voltage dividing unit 125, and the second pin of the first switch module 124 is also connected to the second pin of the rectifier diode module 112 through the voltage dividing unit 125. The voltage dividing unit 125 is also connected to the backup power supply module 123. Thus, through the voltage division of the voltage dividing unit 125, the voltage at the first end of the first switch module 124 is the voltage division of the backup power supply voltage by the voltage dividing unit 125. Therefore, the voltage at the first end of the first switch module 124 is less than the voltage at the second end. As a result, the second end and the third end of the first switch module 124 are turned on, and thus the backup power supply module 123 conducts electrical signal transmission through the first switch module 124. When the power supply module 121 supplies power, under the action of the power supply module 121, the clearing module 122 can be made to short-circuit. As a result, the backup power supply module 123 cannot supply power to the clearing module 122, and the clearing module 122 is in an unturned-on state and cannot perform information clearing. When the power supply module 121 is not supplying power, the power supply module 121 does not affect the clearing module 122. At this time, the backup power supply module 123 can transmit the electrical signal to the clearing module 122, thereby turning on the second end and the third end of the second switch module 1221 of the clearing module 122. As a result, the clearing module 122 can be used to clear the information of the semiconductor memory. Thus, there is no need for professional after-sales personnel to come to disassemble the machine for data clearing. The user can, on their own, make the control module 11 send a control signal to the target module 12 when the power supply module 121 is not supplying power to solve the problem of clearing the information of the semiconductor memory. The operation is simple and convenient, does not require on-site operation by professionals, reduces the waiting time of the user, and lowers the capital cost and time cost.

[0054] In this embodiment, when the control module 11 does not send a control signal to the target module 12, the voltages at the first end and the second end of the first switch module 124 are both the voltage of the backup power supply. Thus, the voltages at the first end and the second end of the first switch module 124 are the same, so the first switch module 124 is not turned on. As a result, the electrical signal of the backup power supply module 123 cannot be transmitted through the first switch module 124, and thus the voltage transmitted at the third end of the first switch module 124 is zero.

[0055] As Figure 5 shown, in the embodiment of the present application, the voltage dividing unit 125 includes a first resistor 1251 and a second resistor 1252. The second pin is connected to the second end of the first switch module 124 and the backup power supply module 123 respectively through the first resistor 1251 and the second resistor 1252. The first resistor 1251 and the second resistor 1252 are connected in series for voltage division.

[0056] In this embodiment, the second pin of the rectifier diode module 112 is connected to the second end of the first switch module 124 through the first resistor 1251 and the second resistor 1252 in sequence. As Figure 5 shown, the first resistor 1251 is Figure 5 R297 in Figure 5 and the second resistor 1252 is R272 in

[0057] As Figure 5As shown, in the embodiment of the present application, the clearing module 122 includes a second switch module 1221. The first end of the second switch module 1221 is connected to the third end of the first switch module 124. The second end of the second switch module 1221 is grounded. The third end of the second switch module 1221 is used to connect to a semiconductor memory.

[0058] In this embodiment, the control module 11 includes an output module 111, a rectifier diode module 112, and an input module 113. The target module 12 includes a first switch module 124, a backup power supply module 123, a clearing module 122, and a power supply module 121. The clearing module 122 includes a second switch module 1221. As Figure 5 shown, the first switch module 124 is Q1, and the second switch module 1221 is Q2. The first end of the first switch module 124 is connected to the second pin of the rectifier diode module 112. The second end of the first switch module 124 is connected to the backup power supply module 123. The third end of the first switch module 124 is connected to the first end of the second switch module 1221. The second end of the second switch module 1221 is grounded. The third end of the second switch module 1221 is used to connect to a semiconductor memory. Thus, when the control module 11 sends a control signal to the target module 12 through the rectifier diode module 112, the second end and the third end in the first switch module 124 of the target module 12 are turned on, and the third end of the first switch module 124 is connected to the first end of the second switch module 1221. When the power supply module 121 is in a power supply state, under the action of the power supply module 121, the clearing module 122 will be in a short-circuit state, so that the backup power supply module 123 will not supply power to the clearing module 122 either. When the power supply module 121 is in a non-powered state, the power supply module 121 will not affect the voltage transmitted to the second switch module 1221. Thus, the backup voltage of the backup power supply module 123 will be transmitted to the first end of the second switch module 1221 through the first switch module 124. When there is a voltage at the first end of the second switch module 1221, the second end and the third end of the second switch module 1221 are turned on. The second end of the second switch module 1221 is grounded, and the third end of the second switch module 1221 is connected to the semiconductor memory, so that it can be used to clear the information of the semiconductor memory, solve the problem of clearing the information of the semiconductor memory, is simple and convenient to operate, does not require on-site operation by professionals, reduces the waiting time of users, and reduces the capital cost and time cost.

[0059] As Figure 5As shown, in the embodiment of the present application, the power supply module 121 includes a third switch module 1211. The first end of the third switch module 1211 is used to connect to a power line. The second end of the third switch module 1211 is grounded. The third end of the third switch module 1211 is respectively connected to the third end of the first switch module 124 and the first end of the second switch module 1221;

[0060] When the first end of the power supply module 121 is electrically connected to the power line, the second end and the third end of the third switch module 1211 are conducting, the clearing module 122 is not electrically connected to the first switch module 124, and the clearing module 122 is in a non-conducting state;

[0061] When the first end of the power supply module 121 is not electrically connected to the power line, the third switch module 1211 is in a non-conducting state, the clearing module 122 is electrically connected to the third end of the first switch module 124 and is in a conducting state, and the clearing module 122 is used to clear the information of the semiconductor memory.

[0062] In this embodiment, the power supply module 121 includes a third switch module 1211. As Figure 5 shown, the third switch module 1211 is Figure 5Q21 in it, Q21 is an NMOS (N-type metal-oxide-semiconductor). The third switch module 1211 has a first end, a second end and a third end. When there is a voltage at the first end of the third switch module 1211, the second end and the third end of the third switch module 1211 can be conducted, while when there is no voltage at the first end of the third switch module 1211, the second end and the third end of the third switch module 1211 are not conducted. The first end of the third switch module 1211 is used to connect to the power supply line, the second end of the third switch module 1211 is grounded, and the third end of the third switch module 1211 is respectively connected to the third end of the first switch module 124 and the first end of the second switch module 1221. When the first end of the third switch module 1211 is electrically connected to the power supply line, there is a voltage at the first end of the third switch module 1211. At this time, the second end and the third end of the third switch module 1211 are conducted. Since the second end of the third switch module 1211 is grounded and the voltage is zero, the voltage derived from the third end that is conducted with the second end in the third switch module 1211 is also zero. Thus, the voltage at the first end of the second switch module 1221 of the erase module 122 connected to the third end of the third switch module 1211 is also zero. As a result, the erase module 122 cannot be electrically connected to the first switch module 124, and thus the second end and the third end of the second switch module 1221 of the erase module 122 cannot be conducted, and the erase module 122 is in a non-conducted state and cannot perform data erasure. When the first end of the third switch module 1211 is not electrically connected to the power supply line, the voltage at the first end of the third switch module 1211 is zero. At this time, the second end and the third end of the third switch module 1211 are not conducted, and the third switch module 1211 is in a short-circuit state. Thus, the first end of the second switch module 1221 is only connected to the third end of the first switch module 124. The first end of the third switch module 1211 receives the voltage sent from the standby power supply module 123 through the first switch module 124. Thus, the second end and the third end of the second switch module 1221 are conducted, and the third end of the second switch module 1221 is connected to the semiconductor memory. Thus, the erase module 122 can erase the information of the semiconductor memory.

[0063] As Figure 4 shown, in the embodiment of the present application, the target module 12 further includes a delay unit 126. The delay unit 126 is connected to the first switch module 124 and the second switch module 1221, and is used to control the control signal transmitted by the control module 11 to the target module 12 to meet the delay threshold of the delay unit 126.

[0064] In this embodiment, the target module 12 includes a first switch module 124, a second switch module 1221 and a delay unit 126. As Figure 5As shown, the first switch module 124 is Q1, the second switch module 1221 is Q2. A delay unit 126 is provided between the third terminal of the first switch module 124 and the second terminal of the second switch module 1221. When the control module 11 sends a control signal to the first switch module 124 through the rectifier diode module 112, when the control signal passes between the third terminal of the first switch module 124 and the first terminal of the second switch module 1221, it is delayed by the delay unit 126. When the control signal meets the delay threshold of the delay unit 126, the control signal can be transmitted through the delay unit 126 to the second switch module 1221, so that when the second switch module 1221 is turned on, it can clear the signal for the connected semiconductor memory.

[0065] In this embodiment, the duration of the pressing output module 111 is controlled according to the delay threshold of the delay unit 126. For example, if the delay threshold of the delay unit 126 is 3 s, the duration of the pressing output module 111 is controlled to be at least 3 s. At this time, the control signal output by the output module 111 can be transmitted to the second switch module 1221 through the delay unit 126, thus preventing the clearing of the semiconductor memory signal caused by accidentally touching the output module 111.

[0066] In this embodiment, the delay unit 126 can be provided between the third terminal of the first switch module 124 and the first terminal of the second switch module 1221. The third terminal of the third switch module 1211 can be connected to the connection line between the third terminal of the first switch module 124 and the delay unit 126, and the third terminal of the third switch module 1211 can also be connected to the connection line between the delay unit 126 and the first terminal of the second switch module 1221.

[0067] As Figure 4 shown, in the embodiment of the present application, the target module 12 further includes a freewheeling diode 127, and the freewheeling diode 127 is connected in parallel with the delay unit 126;

[0068] The delay unit 126 includes a third resistor 1261 and a first capacitor unit 1262. The third resistor 1261 is connected in parallel with the freewheeling diode 127, the first capacitor unit 1262 is connected in parallel with the third resistor 1261 and the freewheeling diode 127, one end of the third resistor 1261 is connected to the third terminal of the first switch module 124, and the other end of the third resistor 1261 is connected to the first capacitor unit 1262.

[0069] In this embodiment, the target module 12 includes a first switch module 124, a second switch module 1221, a delay unit 126 and a freewheeling diode 127. As Figure 5 shown, the first switch module 124 is Figure 5Q1 in it, Q1 is a PMOS (P-type metal-oxide-semiconductor), and the second switching module 1221 is Figure 5 Q2 in it, Q2 is an NMOS (N-type metal-oxide-semiconductor), and the freewheeling diode 127 is Figure 5 D16 in it, which is a freewheeling diode for freewheeling. A delay unit 126 and a freewheeling diode 127 are arranged in parallel between the third terminal of the first switching module 124 and the first terminal of the second switching module 1221. When the control signal passes between the third terminal of the first switching module 124 and the first terminal of the second switching module 1221, the delay unit 126 is used for delaying. When the control signal meets the delay threshold of the delay unit 126, the control signal can be transmitted to the second switching module 1221 through the delay unit 126, so that the second switching module 1221 can clear the signal for the connected semiconductor memory when it is turned on. The freewheeling diode 127 arranged between the first switching module 124 and the second switching module 1221 has the freewheeling diode 127, so that when the delay unit 126 delays the control signal, it can ensure that the current and the signal can flow smoothly at the same time, avoid the occurrence of surge voltage, and thus realize the protection of the components in the target module 12 and avoid damage.

[0070] In this embodiment, the delay unit 126 includes a third resistor 1261 and a first capacitor unit 1262. The third resistor 1261 is arranged between the third terminal of the first switching module 124 and the first terminal of the second switching module 1221. The first capacitor unit 1262 is arranged in parallel with the third resistor 1261. One end of the first capacitor unit 1262 is connected to the connection line between the third resistor 1261 and the second switching module 1221, and the other end of the first capacitor unit 1262 is grounded. Thus, the delay operation of the control signal is realized according to the third resistor 1261 and the first capacitor unit 1262 to control the control signal to meet the delay threshold of the delay unit 126.

[0071] In this embodiment, as Figure 5 shown, the third resistor 1261 is R270, the voltage of the third resistor 1261 can be R3 = 470k, the first capacitor unit 1262 is C443, the capacitance value of the first capacitor unit 1262 can be C = 0.1 μF, and the time constant is R3*C; the initial voltage value on the first capacitor unit 1262 is V0, Vc is the voltage value that the first capacitor unit 1262 can finally charge to or discharge to, and Vt is the voltage value on the first capacitor unit 1262 at time t. Then Vt = V0+(Vc - V0)*[1 - exp(-t / RC)]; or the delay time t = RC*ln[(Vc - V0) / (Vc - Vt)].

[0072] In this embodiment, the first switching module 124 isFigure 5 Q1 in [reference] is a PMOS (P-type Metal-Oxide-Semiconductor), and the second switch module 1221 is Figure 5 Q2 in [reference], Q2 is an NMOS (N-type Metal-Oxide-Semiconductor), and the third switch module 1211 is Figure 5 Q21 in [reference], Q21 is an NMOS (N-type Metal-Oxide-Semiconductor).

[0073] Metal Oxide Semiconductor Field Effect (MOS) transistors Q can be divided into two categories: N-channel and P-channel. The P-channel silicon MOS field effect transistor has two P+ regions on the N-type silicon substrate, called the source and the drain respectively. There is no conduction between the two poles. When a sufficient positive voltage is applied (the source is grounded), a P-type inversion layer appears on the surface of the N-type silicon under the gate, becoming the channel connecting the source and the drain. Thus, when there is a voltage at the first end of the second switch module and the third switch module, the second end and the third end of the second switch module and the third switch module are conducting. When there is no voltage at the first end of the second switch module and the third switch module, the second end and the third end of the second switch module and the third switch module are non-conducting. The first switch module is a PMOS. The PMOS circuit process is simple and inexpensive. It will conduct when Vgs is less than a certain value. The source of the PMOS is connected to VCCRTC. As Figure 2 shown, in the embodiment of the present application, it further includes a circuit board 13. The circuit board 13 is connected to the control module 11 and the target module 12. When the power supply module 121 is in the power supply state, the output module 111 supplies power to the circuit board 13 through the input module 113 to control the turning on or off of the electronic device 1.

[0074] In this embodiment, the electronic device 1 includes a control module 11, a target module 12, and a circuit board 13. The control module 11 includes an output module 111, an input module 113, and a rectifier diode module 112. The output module 111 is connected to the third pin of the rectifier diode module 112. The first pin of the rectifier diode module 112 is connected to the input module 113. The input module 113 and the circuit board 13 are also connected to the circuit board 13. The second pin of the rectifier diode is connected to the target module 12. The output module 111 transmits control signals to the input module 113 and the target module 12 through the rectifier diode module 112. When the power supply module 121 is in the power supply state, the input module 113 receives the control signals and power transmitted by the output module 111, and thus supplies power to the circuit board 13 connected to the input module 113, so as to control the turning on or off of the electronic device 1. When the power supply module 121 is in the non-power supply state, the input module 113 only receives the control signals sent by the output module 111 through the rectifier diode module 112, but does not receive power supply. Thus, the input module 113 cannot supply power to the circuit board 13, and thus cannot control the turning on of the electronic device 1.

[0075] In this embodiment, the target module 12 further includes a fourth resistor 128. As shown in Figure 5 , the fourth resistor 128 is R293. One end of the fourth resistor 128 is connected to the third end of the first switch module 124, and the other end is grounded. When the first switch module 124 is open, the voltage at the third end of the first switch module 124 is clamped to zero.

[0076] In this embodiment, the control module 11 further includes a fifth resistor 129 and a second capacitor unit 130. As shown in Figure 5 , the fifth resistor 129 is Figure 5 R268 in. The fifth resistor 129 is disposed between the output module 111 and the rectifier diode module 112 for maintaining the stability of the current. The second capacitor unit 130 is Figure 5 C416 in. One end of the second capacitor unit 130 is connected to the fifth resistor 129, and the other end is grounded for maintaining the stability of the signal.

[0077] In this embodiment, the control module and the target module of the electronic device include a first resistor, a second resistor, a third resistor, a fourth resistor, and a fifth resistor. The above are all resistor structures, and their resistance values are set according to requirements as long as they meet production and application requirements.
