Problems solved by technology

[0003] At present, there are still great defects and deficiencies in traditional home furnishing. First, there are too many and too complicated smart home products. Most of them are devices with only a single function, and different devices are not compatible. It is difficult to achieve the systematization of smart home ; Second, for non-professionals, it is impossible to assemble many systems into a smart home system; third, the installation and maintenance work is cumbersome, and most families do not consider the needs of smart homes from the beginning of decoration. To renovate the existing house, which has caused troubles such as secondary decoration, rewiring, etc., and inconvenient construction of equipment on the original basis

Embodiment 1

[0022] A smart home control and security system based on WIFI technology is mainly characterized in that figure 1 It mainly includes two STM32 microcontroller main control modules (1) (2), voice control module (3), fire monitoring module (4), acceleration detection module (5), infrared signal receiving module (6), A WIFI communication module (7), an LCD display module (8), a data storage module (9), a camera image acquisition module (10), an environment detection module (11), and a household electrical appliance (12), among which various The protocol communicates with external sensors, and is equipped with a power supply voltage regulator module to connect the household 220V mains to the equipment for stable operation;

[0023] The environment detection module is as image 3 Shown: It includes the collection of PM2.5 in the home environment, the temperature and humidity of the environment, the light intensity, and the atmospheric pressure. All modules use high-precision indus...

Embodiment 2

[0030] A schematic diagram of the structure of a smart home control and security system based on WIFI technology is as follows figure 1 As shown, the main methods of the image acquisition module (10) and the data storage module (9) are as follows: the system supplies power through a 5V power supply module, supplies power to the single-chip microcomputer through a 3.3 voltage regulator chip, and then manages the camera power supply through the single-chip microcomputer. When the single-chip microcomputer controls the power of the camera to be turned on, the camera starts to work, and the camera passes the collected image through the field-line separation chip to obtain the field signal and the line signal. When copying a complete image, transfer the data to the data storage module.

[0031] The power conversion module such as figure 2 As shown in the figure, because the system is connected to the mains 220V, it cannot directly provide power for the system devices, and must pa...

Embodiment 3

[0033]A wireless upgrade technology of a smart home control and security system based on WIFI technology is shown in Figure (6). The present invention uses the IAP function of STM32 and designs the Bootloader code to realize the update of the device application program through the communication network, which is different from the traditional wired update. In contrast, the operator does not have to be on site to update the device firmware, which greatly reduces maintenance costs.

[0034] The device function of a smart home control and security system based on WIFI technology involved is relatively complex, including environmental monitoring, voice recognition, infrared control, vibration analysis, image storage, etc., and the use of single-chip bare metal to directly run a single-threaded program will lead to the system. The stability of the system is reduced, so the system transplants the ucosiii system into the equipment, and is equipped with a multi-task real-time system to...
