Communication method between mobile phone and Raspberry Pi based on cloud database

Abstract

The invention discloses a communication method between a mobile phone and a Raspberry Pi based on a cloud database. The method specifically comprises the following steps that 1, a Python script program on the Raspberry Pi controls the hardware equipment by calling a GPIO port, and the Python program controls the high level and the low level of the GPIO port to achieve on-off of a lamp; step 2, themobile phone and the raspberry pi access mutually through ajax under the same wifi, and a program is called at a server side through php to realize interaction, thereby realizing data synchronization; step 3, the cloud server accesses the Raspberry Pi control terminal and the mobile phone app through the ajax based on the http and websocket protocols; and step 4, a background program of the cloudserver to add, delete, modify and check the cloud database. The Raspberry Pi and the mobile phone serve as terminals, the important data and programs are uploaded to the server side, and the server side stores the data in the cloud server through the background program, so that the data sharing and the program real-time modification are achieved.

Description

technical field [0001] The invention relates to a communication method, in particular to a communication method between a mobile phone and a raspberry pie based on a cloud database. Background technique [0002] In the prior art, the mobile app and the Raspberry Pi can communicate through Bluetooth. The mobile app generates instructions to send data to the Raspberry Pi through Bluetooth, and the Raspberry Pi receives the data through Bluetooth; otherwise, the Raspberry Pi sends data to the mobile app, and the mobile app receives it through Bluetooth. The obvious disadvantages of this technical solution are: 1. Short transmission distance: Bluetooth is a wireless technology standard, which belongs to the local area network, and the transmission data has a range limit. When the distance between the Raspberry Pi and the mobile phone exceeds this range, data transmission It will be unstable or even unable to connect. 2. Unable to realize multi-user data sharing: The mobile app...

AI Technical Summary

Problems solved by technology

The obvious disadvantages of this technical solution are: 1. Short transmission distance: Bluetooth is a wireless technology standard, which belongs to the local area network, and the transmission data has a range limit. When the distance between the Raspberry Pi and the mobile phone exceeds this range, data transmission become unstable or even unable to connect

2. Unable to achieve multi-user data sharing: the mobile app and Raspberry Pi communicate through point-to-point mode. Since the databases are all personal databases, multiple user data sharing cannot be achieved

3. Inconvenient software upgrade in the later stage: because the operating program is encapsulated in the product, product users cannot maintain and upgrade the product

The obvious disadvantages of this technical solution are: high cost, poor stability, consumption of computing and storage resources on the server side, etc.
