Description

Technical Field

[0001] This utility model relates to the field of electronic equipment manufacturing and development technology, and in particular to an infrared-based wireless upgrade device. Background Technology

[0002] In fields such as electronic equipment manufacturing and embedded system development, software development and hardware upgrades typically require pre-writing the software program or code into a computer, then opening the casing of the device to be upgraded, connecting it to the computer via a cable and a programmer, and finally installing the programming software on the computer to perform the upgrade. This programming method is cumbersome and complex, and for upgrading large numbers of devices, it involves a huge workload. Another method uses an automatic programmer, but these programmers are bulky, and their price, maintenance, and update costs are relatively high. Due to hardware limitations, their applicability is narrow, only suitable for programming specific chips. Therefore, there is an urgent need for a new type of wireless upgrade device to improve the efficiency and convenience of upgrades. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide an infrared-based wireless upgrade device to address the shortcomings of existing technologies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An infrared-based wireless upgrade device includes a handheld upgrade device and a device to be upgraded. The handheld upgrade device includes a Type-C charging interface, a power management circuit, an upgrade device processor, button selection / control, an LCD screen, indicator lights, and an infrared emitting circuit. The button selection / control includes a logic control chip U2, a down button SW2, a power button SW3, and an OK button. The device to be upgraded includes an integrated infrared receiver chip U1, a filter capacitor C1, a device to be upgraded processor, LED indicator lights, and an LCD screen.

[0005] As a further improvement of this utility model, the infrared emitting circuit includes a current-limiting resistor, an infrared emitting tube D1, an NPN transistor Q1, and an upper button SW1. The current-limiting resistor includes a current-limiting resistor R1 and a current-limiting resistor R2.

[0006] As a further improvement of this utility model, terminal 2 of the upper button SW1 is connected to one end of the upgrade device processor, the other end of the upgrade device processor is connected to the current limiting resistor R1, the other end of the current limiting resistor R1 is connected to terminal 2 of the NPN transistor Q1, terminal 3 of the NPN transistor Q1 is connected to the current limiting resistor R2, and the other end of the current limiting resistor R2 is connected to the infrared emitting tube D1.

[0007] As a further improvement of this utility model, one end of the integrated infrared receiver chip U1 is connected to one end of the processor of the device to be upgraded, and the other end of the processor of the device to be upgraded is connected to the LED indicator and the LCD display.

[0008] As a further improvement of this utility model, the Type-C charging interface of the handheld upgrade device includes a charging chip U4, the power management circuit includes a voltage conversion chip U3, the button selection / control includes a logic control chip U2, a down button SW2, a power button SW3, and an OK button. The charging chip U4 provides a stable voltage to the handheld upgrade device and then outputs a 3.3V voltage to the upgrade device processor through the voltage conversion chip U3. The logic control chip U2 controls the power on or off of the handheld upgrade device by recognizing the short or long press action of the power button SW3.

[0009] As a further improvement of this utility model, the handheld upgrade device reuses the upper button SW1, that is, by pressing and holding the upper button SW1 (for example, the preset time is 2 seconds), the infrared emitting tube D1 emits an infrared light signal.

[0010] As a further improvement of this utility model, infrared wireless transmission is performed between the infrared emitting tube D1 and the integrated infrared receiving tube chip U1.

[0011] As a further improvement of this utility model, the handheld upgrade device is powered by a lithium battery and can operate normally while charging.

[0012] As a further improvement of this utility model, both the handheld upgrade device and the device to be upgraded use LED indicator lights to indicate the communication status and an LCD display screen to indicate the upgrade progress.

[0013] As a further improvement of this utility model, the LED indicator light of the handheld upgrade device flashes when it emits infrared light, and remains constantly lit in other states.

[0014] The beneficial effects of this utility model are: 1. This utility model provides an infrared-based wireless upgrade device. The handheld upgrade device has a built-in rechargeable lithium battery. When the power button SW3 is pressed briefly, KEY outputs a 200ms low pulse, P_KEY outputs a high level, and U3 outputs 3.3V. After the handheld upgrade device is powered on and the screen lights up, the user can select the program to be upgraded by pressing the up button SW1 or the down button SW2 briefly. After clicking the confirmation button, when the handheld upgrade device and the device to be upgraded are close together, the up button SW1 is pressed and held (for example, the preset time is 2 seconds). The internal microcontroller sets the TX pin to a high level, the transistor Q1 conducts, and the infrared emitting tube D2 works and radiates the corresponding infrared signal. The device to be upgraded has an integrated infrared receiving chip U1, which converts the received infrared signal into an electrical signal and sends it to the processor of the device to be upgraded through the RX pin. After successful communication between the two, the handheld upgrade device sends the pre-stored program to the infrared receiving chip U1 of the device to be upgraded again in the form of an infrared signal, that is, it performs the burning. During the burning process, the upgrade progress can be observed on the display screens of both the handheld upgrade device and the device to be upgraded. After the programming process is complete, press and hold the power button SW3 (assuming the preset time is 3 seconds). The KEY outputs two low pulses with a 200ms interval and a 500ms interval, and the P_KEY outputs a low level, thus powering off the handheld upgrade device.

[0015] 2. This infrared-based wireless upgrade device solves the complexity of traditional programming methods that require opening the casing and reserving interface wiring, as well as the bulkiness and limitations of automatic programmers. Furthermore, the handheld upgrade device can communicate with multiple devices to be upgraded simultaneously, allowing for simultaneous programming of multiple devices. The devices to be upgraded use chips with integrated infrared receivers, resulting in faster processing speeds. The use of integrated chips also reduces the number of components in the circuit design, lowering the probability of problems and reducing future maintenance costs. Both the handheld upgrade device and the devices to be upgraded use displays to indicate the upgrade progress, facilitating faster troubleshooting in case of issues during the upgrade process. This type of wireless upgrade device is suitable for upgrading various types of firmware and software formats, meeting the needs of different fields. Attached Figure Description
