The summer harvest is coming to an end. Pay attention to the "black technology" in the grain warehouse. What kind of help do these "black technologies" bring...

1. The report that China's Zhengzhou Direct Grain Storage Bank realizes green grain storage through scientific and technological means to ensure the safety of wheat purchase and storage has attracted wide attention, so that traditional grain storage can create "black science Technology" digital and intelligent business.

2. Micro-air conditioning systems have appeared in many places, which can automatically filter viruses in high temperatures in summer. Don't worry that it will take up a large area in the house, and the volume is very small. In the hot summer, everyone's home is very hot. After having these, you can solve the problem very well.

3. Recently, JD.com's ecological partners have seen technology based on JD.com's artificial intelligence open platform NeAI capabilities such as image recognition provided by uHub have launched a "super glasses", which is applied to store intelligent shopping guide, intelligent inventory and intelligent store patrol in the form of intelligent wearable devices to help offline retail reduce costs and improve efficiency.

4. What are the black technologies of Huawei mate60? Satellite calls. Huawei Mate60 series will support the domestic PA power amplifier chip, and then cooperate with the Tiantong-1 satellite mobile communication system to realize the satellite call function, not just limited to the transmission of satellite messages.

5. In the Winter Olympics Village, there is also an intelligent screen projection, which can learn Chinese martial arts. The player's bed can also play a massage role, and it can also be folded, which can make the indoor space larger. The curtains of the floor-to-ceiling windows in the athlete's room are automatic and can be controlled in various places in the room.

6. Voice control technology of the movie "True Lies" If the audience who has seen early science fiction movies, it is not difficult to find that the most high-tech in these films is the voice control system. Compared with fingerprint recognition and iris recognition, voice control technology is more intuitive and does not require special effects.

The implementation process of the granary environmental monitoring system based on wifi module?

1. Monitoring station software can be implemented directly through C or assembly language, and application software can also be developed on real-time operating systems. For low-gear 4-bit or 8-bit single-chip microcomputers, the control ability is low, the system is simple, and the method of directly writing control programs is generally adopted.

2. Seismic monitoring By using a sensor network composed of a large number of interconnected micro-sensor nodes, continuous high-precision data collection can be carried out for different environments. The adoption of low-power wireless communication modules and wireless communication protocols can make the life of the sensor network last for a long time. Ensure the practicality of the sensor network.

3. The module integrates the complete Wi-Fi and Bluetooth application requirements.The hardware and software resources can support AP and STA dual-role connections, and also support classic Bluetooth and low-power Bluetooth connections. And it integrates priority-based Wi-Fi and Bluetooth coexistence control modules to achieve real-time priority and sending and receiving scheduling.

4. Wireless mobile sensor: The sensor becomes a wireless mobile sensor by integrating the WIFI wireless mobile module. The mine monitoring system can use wireless mobile sensors to obtain monitoring data from all over the underground in real time.

How to use the barn crowdsourcing platform
