Abstract
Description
Technical Field
[0001] The present invention relates to a converter, and in particular to a rechargeable LoRa to Type-C converter. Background Art
[0002] When debugging a device with LoRa radio frequency, to check whether the LoRa module is sending and receiving data normally, you often need to use a computer to configure another device with LoRa module. In addition, to detect the data sent and received by the LoRa module, the corresponding device needs to transfer it to the serial port so that the corresponding data can be seen on the computer.
[0003] Due to the advantages of high efficiency and low power consumption of LoRa wireless transmission, in some overseas power markets, electric meters use LoRa to transmit signals. LoRa (Long Range) is a modulation technology and one of the low-power wide area network communication technologies. It is an ultra-long-distance wireless transmission technology based on spread spectrum technology and can be used for different protocols and different network architectures. Usually, the electric meter is hung under the information collection device, and the information collection device collects the meter information through LoRa transmission signals. When the collection device is offline, that is, the main node of the meter is turned off, the on-site technicians have no way to directly obtain the meter information through the collection device. Collecting meter data information through a signal transfer device and converting it into information that can be received by a mobile phone, and displaying it through a mobile phone APP is a solution, but there is currently a lack of a low-cost and easy-to-carry signal transfer device on the market. Summary of the invention
[0004] In order to overcome the above existing phenomenon, the purpose of the present invention is to provide a rechargeable LoRa to Type-c converter. It can directly connect to the Typc-c interface on the mobile phone through the Type-c interface, and can also connect the mobile phone end and the electric meter end, and transfer the electric meter signal to the mobile phone, directly avoiding other troubles during detection. The converter is powered by a lithium battery, is rechargeable, and is easy to carry.
[0005] In order to achieve the above object, the technical solution adopted by the present invention is: A rechargeable LoRa to Type-C converter comprises a microprocessor (1), characterized in that the microprocessor (1) is connected to a power management module, a first signal input / output of the microprocessor (1) is bidirectionally connected to a LoRa module (9), a second signal input / output of the microprocessor (1) is bidirectionally connected to a first input / output of a serial port to Type-C chip (6), and the second input / output of the serial port to Type-C chip (6) is connected to a mobile phone terminal (8) via a Type-C interface (7); the microprocessor (1) is provided with a Bluetooth module (12) and a signal conversion module (10); and the LoRa module (9) is connected to an electric meter (11).
[0006] The power management module comprises a switch (4), a lithium battery with a charger (3) and an LDO chip, and is provided with an external power port (5). The LDO chip is used to convert the 5V voltage output by the power management module into 3.3V and supply power to each functional module.

[0008] The serial port to Type-C chip (3) is used to convert corresponding data and communicate with the mobile phone (8) via the Type-C interface (7).
[0009] The LoRa module (9) is connected to the microprocessor (1) and is used to obtain the meter data collection command of the microprocessor (1) and forward the command to the meter, and at the same time receive and transmit the data sent by the meter to the microprocessor (1).
[0010] The Bluetooth module is connected to the microprocessor (1) and is used to obtain the meter data acquisition command sent by the mobile phone and send it to the microprocessor (1), while transmitting the meter data obtained by the microprocessor (1) to the mobile phone.
[0011] The signal conversion module is connected to the microprocessor (1) and is used to communicate with the host computer and obtain parameter adjustment information and send it to the microprocessor (1), thereby configuring relevant parameters of the Lora module.
[0012] The power supply module is used to supply power to other functional modules.

Under the same power consumption conditions, it can transmit farther than other wireless methods, achieving the unity of low power consumption and long-distance characteristics. And under the same power consumption, it can expand the communication distance by 3-5 times compared with traditional wireless radio frequency, and can work for 5-10 years in an environment with only battery power supply. Users can directly configure the LoRa parameters on the converter through their mobile phones, and can receive, send and charge data through their mobile phones. BRIEF DESCRIPTION OF THE DRAWINGS
