If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0050] This invention proposes a portable one-button charging communication circuit.

[0051] In one embodiment of the present invention, such as Figure 1 As shown, the portable one-button charging communication circuit includes a main control chip 10, a button control circuit 20, a charging circuit 30, and a near-infrared communication circuit 40.

[0052] The interactive terminal of the button control circuit 20 is connected to the interactive terminal of the main control chip 10, the interactive terminal of the charging circuit 30 is connected to the interactive terminal of the main control chip 10, and the interactive terminal of the near-infrared communication circuit 40 is connected to the interactive terminal of the main control chip 10.

[0053] The main control chip 10 is used to output power to the connected circuits and receive signal information from various circuits after reading that the button control circuit 20 has entered the power-on state. For example, if the main control chip 10 reads that the button control circuit 20 has entered the power-on state, the main control circuit sends power to other connected circuits, such as the charging circuit 30 and the near-infrared communication circuit 40 (in this embodiment, the power supply is 3.3V), so that the circuit of the near-infrared upgrader enters the working state. If the button control circuit 20 is read to enter the recognition state, the main control chip 10 reads the upgrade program from the storage chip 70 and sends it to the near-infrared communication circuit 40. The upgrade program of the near-infrared communication circuit 40 is converted into infrared light to establish communication and upgrade the device to be upgraded.

[0054] The key control circuit 20 is used to adjust the level state of the power enable pin, upgrade enable pin and key input pin according to the received key signal information, so that the main control chip 10 can control the connected circuit accordingly by reading the level state of different pins.

[0055] The charging circuit 30 is used to supply power to the main control chip 10 through the first diode D1 or the second diode D2. When a USB cable is inserted into the USB interface J1, the USB interface J1 supplies power to the circuit system of the near-infrared upgrader through the first diode D1. If no USB cable is detected inserted into the USB interface J1, the battery VABT supplies power to the circuit system of the near-infrared upgrader through the second diode D2.

[0056] The near-infrared communication circuit 40 is used to send an infrared signal converted by the upgrade program to the device to be upgraded corresponding to the infrared signal after receiving the infrared signal sent by the device to be upgraded.

[0057] Specifically, such as Figure 2 As shown, the charging circuit 30 includes a USB interface J1, a controller U1, and a battery VABT;

[0058] The power terminals of the USB interface J1 are connected to the positive terminal of the first diode D1 and the power receiving terminal of the controller U1, respectively. The power output terminal of the controller U1 is connected to the input terminal of the battery VABT, and the output terminal of the battery VABT is connected to the positive terminal of the second diode D2.

[0059] In this embodiment, the charging circuit 30 has two cases: one is when a USB cable is inserted into the USB interface J1, and the other is when no USB cable is inserted into the USB interface J1.

[0060] ① USB cable plugged into USB interface J1: When a USB cable is detected at the USB interface, it indicates that an external device is connected to the near-infrared upgrader. Therefore, voltage is extracted from the external device via the USB cable. At the same time, the extracted 5V voltage (because the current USB interface only has a 5V voltage) is transmitted to the main control chip 10 through the first diode D1. The extracted 5V voltage is also output to the battery VABT through the power receiving and power output terminals of the controller U1 to charge the battery VABT. The charging status of the battery VABT is output through the BAT_CHG pin of the controller U1. When the controller U1 reads the charging information, the BAT_CHG pin outputs a pulse signal. The pulse signal causes the diode in the charging circuit 30 to flash red at a flashing speed of 200ms to indicate to the user that charging is in progress. When the controller U1 reads the charging completion information, the BAT_CHG outputs a high signal. The high signal causes the diode in the charging circuit 30 to light up green to indicate to the user that charging is complete.

[0061] ② No USB cable inserted into USB interface J1: After receiving the signal information of entering the power-on state sent by the main controller U1, the battery VABT automatically outputs 5V voltage to the main control chip 10 through the second diode D2, so that the main control chip 10 can convert the received 5V voltage into 3.3V power supply to supply power to the circuit connected to it in a timely manner.

[0062] Specifically, such as Figure 3 As shown, the button control circuit 20 includes a rectifier diode VD1, a button switch K1, a third diode D3, and a fourth diode D4;

[0063] The output terminal of the rectifier diode is connected to pins 3 and 4 of the push-button switch, pins 1 and 2 of the push-button switch are connected to the positive terminal of the fourth diode D4, and the upgrade enable pin is located on the positive terminal of the third diode D3.

[0064] Furthermore, the button control circuit 20 also includes a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, and a fifth resistor R5;

[0065] One end of the first resistor R1 is connected to the negative terminal of the third diode D3, and the other end of the first resistor R1 is connected to one end of the third resistor R3. The other end of the third resistor R3 is grounded. One end of the second resistor R2 is connected to the negative terminal of the fourth diode D4, and the other end of the second resistor R2 is connected to the connection point of the first resistor R1 and the second resistor R2. One end of the fourth resistor R4 is connected to pins 1 and 2 of the push-button switch, and the other end of the fourth resistor R4 is connected to one end of the fifth resistor R5. The other end of the fifth resistor R5 is grounded.

[0066] The power enable pin is located on the extension line of the connection point of the first resistor R1, the second resistor R2 and the third resistor R3, and the key input pin is located on the extension line of the connection point of the fourth resistor R4 and the fifth resistor R5.

[0067] like Figure 3 As shown, VABT is the battery output, and 3V3 is the 3.3V power supply output from the main control chip 10. Both of these power supplies, after passing through a rectifier diode, pull up pins 3 and 4 of the push-button switch. Because the voltage flowing through the rectifier diode makes the forward voltage of the rectifier diode greater than the dead zone voltage, it can effectively overcome the blocking effect of the battery in the PN junction, allowing the rectifier diode to conduct in the forward direction. The current rises rapidly as the voltage increases, thereby pulling up pins 3 and 4 of the push-button switch. The conducting rectifier diode can also stabilize the voltage.

[0068] The button control circuit 20 is divided into three states based on the received button signals: power-on state, recognition and upgrade state, and power-off state.

[0069] ①Power-on state: When the near-infrared upgrader's system circuit is in the power-off state, the button switch is pressed. At this time, pins 1 and 2 and pins 3 and 4 of the button switch are short-circuited. After the short circuit, pins 1 and 2, which are pulled high, pull the power enable pin TPS_EN high through the fourth diode D4. After the main control chip 10 reads the high level of the power enable pin TPS_EN, it turns on the power of the near-infrared upgrader and enters the power-on state. At this time, the button input pin KEY_PRG is pulled low through the fifth resistor R5.

[0070] ② Upgrade Status Identification: When the near-infrared upgrader's system circuit is powered on, if the button switch is pressed for no longer than a preset duration (e.g., 3 seconds), the upgrade enable pin POWER_EN will be pulled high to 3.3V. This 3.3V voltage will then continuously pull the power enable pin TPS_EN high through the third diode D3 and the first resistor R1. At this time, the button input pin KEY_PRG will be pulled high by the fourth resistor R4. After reading the high level of the button input pin KEY_PRG, the main control chip 10 sends an upgrade identification signal to the near-infrared communication circuit 40 and the storage chip 70, thus entering the upgrade identification state.

[0071] ③ Power-off state: When the near-infrared upgrader's system circuit is in the power-on state or the upgrade recognition state, if the button switch is pressed for more than the preset duration, the button input pin KEY_EN will be pulled high for more than 3 seconds by the fourth resistor R4, which in turn will cause the upgrade enable pin POWER_EN to be pulled low for more than 3 seconds. Therefore, when the button switch is released, the power enable pin TPS_EN will be pulled low by the third resistor R3. After reading the low level state of the power enable pin TPS_EN, the main control chip 10 will cut off the power supply to the near-infrared upgrader, causing the near-infrared upgrader to enter the power-off state.

[0072] Specifically, such as Figure 4 As shown, the near-infrared communication circuit 40 includes an infrared receiving circuit and an infrared transmitting circuit;

[0073] The output terminal of the infrared receiving circuit is connected to the input terminal of the infrared transmitting circuit.

[0074] like Figure 4 The two circuit diagrams shown are located in Figure 4 The upper part of the circuit diagram is the infrared receiving circuit, located in... Figure 4 The lower part of the circuit diagram is the infrared transmitting circuit.

[0075] The infrared receiving circuit is used to identify the infrared signals of the surrounding devices to be upgraded when the near-infrared upgrader enters the identification upgrade state.

[0076] The infrared transmitting circuit is used to send an infrared signal containing the upgrade program to the device to be upgraded when the infrared receiving circuit detects an infrared signal from a nearby device to be upgraded.

[0077] Furthermore, the infrared receiving circuit includes a receiving diode IRR1, a first transistor Q1, an amplifier U1A, a comparator U2A, and a voltage output pin IRRxD;

[0078] The positive terminal of the receiving diode IRR1 is connected to the power supply, the negative terminal of the receiving diode IRR1 is connected to the base of the first transistor Q1, the emitter of the first transistor Q1 is connected to the inverting input terminal of the amplifier U1A, the output terminal of the amplifier U1A is connected to the inverting input terminal of the comparator U2A, and the voltage output pin IRRxD is located on the output terminal of the comparator U2A.

[0079] When the receiving diode IRR1 in the infrared receiving circuit does not receive an infrared signal, almost no current flows through it. Therefore, the voltage at the output of amplifier U1A is equal to the voltage at the non-inverting input of amplifier U1A. Consequently, the voltage output from amplifier U1A to the inverting input of comparator U2A is less than the voltage at the non-inverting input of comparator U2A, which in turn causes the voltage output from comparator U2A to the voltage output pin IRRxD to be high.

[0080] When the receiving diode IRR1 in the infrared receiving circuit receives an infrared signal, the current flowing through the receiving diode IRR1 will increase. Therefore, the voltage at the output terminal of amplifier U1A will be greater than the voltage at the non-inverting input terminal of amplifier U1A (voltage at the output terminal of amplifier U1A = voltage at the non-inverting input terminal of amplifier U1A + voltage of the first transistor Q1). Consequently, the voltage output from the output terminal of amplifier U1A to the inverting input terminal of comparator U2A will be greater than the voltage at the non-inverting input terminal of comparator U2A, thus causing the voltage output pin IRRxD of comparator U2A to be at a low level.

[0081] Depend on Figure 4 It can be seen that the non-inverting input terminals of amplifier U1A and comparator U2A both receive a 3.3V power-on supply, and the capacitors and resistors in them serve as filters.

[0082] Furthermore, the infrared transmitting circuit includes an emitting diode DDT1, a second transistor Q2, and;

[0083] The positive terminal of the emitting diode DDT1 is connected to the collector of the second transistor Q2, the negative terminal of the emitting diode DDT1 is grounded, and the voltage input pin IRTxD is located on the base of the second transistor Q2.

[0084] like Figure 4 As shown, the voltage output pin IRRxD in the infrared transmitting circuit is connected to the voltage input pin IRTxD in the infrared receiving circuit.

[0085] When the voltage input pin IRTxD outputs a high level to the base of the second transistor Q2, current flows from the base to the collector of the second transistor Q2, and at the same time, the emitter current flows to the collector, which will cause a short circuit between the collector and the emitter, causing the second transistor Q2 to not conduct. At this time, no current flows through the emitter diode DDT1, so the emitter diode DDT1 does not emit light.

[0086] When the voltage input pin IRTxD outputs a low level to the base of the second transistor Q2, the base current of the second transistor Q2 is cut off, and the 3.3V power-on current can flow smoothly from the emitter to the collector, turning on the second transistor Q2. At this time, current flows through the emitting diode DDT1, so the emitting diode DDT1 lights up and simultaneously sends an infrared light signal with the upgrade program to the corresponding device to be upgraded.

[0087] The resistors in the infrared transmitting circuit are pull-up resistors and filter resistors.

[0088] Specifically, such as Figure 1 As shown, the portable one-button charging communication circuit also includes a USB interface 50 and a USB communication chip 60;

[0089] The interaction terminal of the USB communication chip 60 is connected to the interaction terminal of the USB interface 50, and the interaction terminal of the USB communication chip 60 is connected to the interaction terminal of the main control chip 10.

[0090] The USB communication chip 60 is located between the USB interface 50 and the main control chip 10. When the user sends an upgrade program or other data program to the near-infrared upgrader through the USB interface 50, the USB communication chip 60 can transmit the received upgrade program or other data program to the main control chip 10.

[0091] Specifically, such as Figure 1 As shown, the portable one-button charging communication circuit also includes a memory chip 7070;

[0092] The interaction terminal of the storage chip 70 is connected to the interaction terminal of the main control chip 10;

[0093] After the main control chip 10 receives the upgrade program or other data program through the USB communication chip 60, it sends the received upgrade program or other data program to the storage chip 70 for offline storage. When the portable one-button charging communication circuit, i.e. the near-infrared upgrader, enters the identification and upgrade state, it sends the upgrade program or other data program to the main control chip 10. The main control chip 10 sends the upgrade program or other data program to the near-infrared communication circuit 40, and based on the near-infrared communication circuit 40, it converts the upgrade program or other data program into infrared light containing the upgrade program or other data program and sends it to the device to be upgraded, thus completing the upgrade operation of the device to be upgraded.

[0094] Detailed operation function description

[0095] like Figure 5 The miniature near-infrared upgradeer shown has an infrared adsorption head for aligning with the infrared head of the device to be upgraded, an indicator light to show the user the current status of the miniature near-infrared upgradeer, buttons for easy switching of the status of the miniature near-infrared upgradeer, and a USB interface for connecting external devices to charge the miniature near-infrared upgradeer and send upgrade programs and other data programs.

[0096] When the user presses and holds the power button while the mini near-infrared upgrader is off, the upgrader will be powered on. At this time, the two indicator lights will switch from being off to solid red. When the infrared adsorption head is aligned with the infrared head of the device to be upgraded, the user presses the button briefly (in this embodiment, the brief press duration is no more than 3 seconds, and the duration can be set by the user) to put the mini near-infrared upgrader into the identification and upgrade state. At this time, the right indicator light will flash red. When the upgrade operation of the mini near-infrared upgrader on the device to be upgraded is completed, the right indicator light will solid green.

[0097] When the miniature near-infrared upgrader is charging, the left indicator light flashes red. When charging is complete, the left indicator light stays on green.

[0098] This embodiment also proposes a miniature near-infrared upgrader, which includes the portable one-button charging communication circuit described above, including a main control chip 10, a button control circuit 20, a charging circuit 30, and a near-infrared communication circuit 40.

[0099] The interactive terminal of the button control circuit 20 is connected to the interactive terminal of the main control chip 10, the interactive terminal of the charging circuit 30 is connected to the interactive terminal of the main control chip 10, and the interactive terminal of the near-infrared communication circuit 40 is connected to the interactive terminal of the main control chip 10.

[0100] The main control chip 10 is used to output power to the connected circuit and receive signal information from each circuit after reading that the key control circuit 20 has entered the power-on state.

[0101] The key control circuit 20 is used to adjust the level states of the power enable pin, the upgrade enable pin, and the key input pin according to the received key signal information.

[0102] The charging circuit 30 is used to supply power to the main control chip 10 through the first diode D1 or the second diode D2;

[0103] The near-infrared communication circuit 40 is used to receive and transmit infrared signal information.

[0104] The specific structure of the miniature near-infrared upgrader is as described in the above embodiments.
