Long-distance temperature and humidity monitoring method and system based on mobile phone

Abstract

The invention provides a long-distance temperature and humidity monitoring system based on a mobile phone. The system comprises a client-side, a signal transition system, a data collecting system and a controlling system. The data collecting system and the controlling system are connected respectively through the signal transition system and the client-side system. The invention further provides a long-distance temperature and humidity monitoring method based on the mobile phone. Operations of the data collecting system and the controlling system can be controlled through the mobile phone by a user. Application software of the method and the system is based on an open-source android operation system, and therefore operation cost of the system is reduced, and portability of the system is improved.

Description

technical field [0001] The invention relates to the technical field of remote temperature and humidity control, in particular to a remote temperature and humidity monitoring method and system based on an android mobile phone. Background technique [0002] At present, most remote temperature and humidity monitoring systems use PC as the control and application terminal, and carry out data transmission and monitoring through RS-232 / 422 / 485 and other field buses, or use Internet+GPRS for remote monitoring. Adopting the method of PC combined with single-chip microcomputer control system, that is, the mode of upper computer + lower computer, to realize the remote collection and equipment control of temperature and humidity. The operator sends the corresponding control command on the PC application terminal, and sends the control command to the control terminal in a wired or wireless manner to realize the opening and closing of the actuator. [0003] However, the temperature and ...

Problems solved by technology

[0005] However, the temperature and humidity monitoring system using PDA or Widows Mobile as the application terminal, on the one hand, its data transmission links are mostly GSM and GPRS, which increases the transmission cost and cannot meet the requirements of mass data transmission such as video and pictures. On the other hand, its operating system mostly uses WinCE or Widows Mobile operating system, which makes the development of its application system not flexible enough, free, and secondary development is relatively difficult, and it is necessary to purchase the corresponding authorization when it is put into mass production, which greatly Increased operating cost of the system
