Description

technical field [0001] The invention relates to a mobile device supporting wide-area wireless connection, in particular to a mobile smart phone-based wide-area wireless mobile device and a control method thereof. Background technique [0002] At present, since smart wireless mobile devices can already be equipped with monitoring and sensor equipment to replace humans for accurate perception of the environment, and can transmit the corresponding sensory data information and image information to the background through the wireless network, the operator can completely observe the environment through the background. The corresponding data information and image information are controlled through wireless network communication. Therefore, intelligent wireless mobile devices have been widely used in important fields such as mobile monitoring, investigation, environmental monitoring, anti-terrorism and disaster relief. [0003] The invention patent with the patent publication number...

AI Technical Summary

Problems solved by technology

However, the embedded multifunctional smart car has the following defects: First, the scope of use is limited, and the mobile device is connected to the monitoring terminal using a wifi local area network. The coverage of the wifi local area network is limited, and wide area control cannot be realized.

The second is that the system coupling is too high. The smart car is equipped with a fixed sensor module. Although some functions are functional modules that can be tailored, when different sensors need to be added in different environments, the system needs to be re-customized to cope with different uses. surroundings

But this smart car wireless monitoring system also has the following defects: First, the scope of use is limited

Although this solution does not use wifi to realize the network connection between the console and the control terminal, it uses the wireless communication module SI4432 and the wireless video transmission module JAV-RX2288. The effective and stable transmission distance is within 300 meters. The transmission distance is short, and the wide area network connection cannot be realized , the control range is small

Second, the system coupling degree is high

Third, the control process is complex

The existing intelligent wireless mobile devices mainly realize the connection between the mobile device and the background through the wifi local area network. Due to the limited coverage of the wifi local area network, wide area control cannot be realized, so the scope of use is small

[0007] Second, the system coupling is too high

The systems in the existing schemes are all customized systems, and the coupling degree among the various modules in the system is high. The specific background can only operate the corresponding mobile device, and the data of the mobile device can only be parsed by the corresponding background, which leads to system maintenance and upgrade. And the high cost and difficulty of secondary development

[0008] Third, the control process is complex

The system in the existing solution sends detailed monitoring data and images of the device to the background through the wifi module, and the operator makes corresponding judgments, and sends control commands through wifi to operate the mobile device to realize simple actions, and the data transmission process is very unstable. , prone to data packet loss and other phenomena, resulting in inaccurate post-control instructions
