Abstract

The invention relates to a hand-held terminal used for data acquisition and transmission of condition of stored grain, which comprises a humiture sensor, an interface module, a wireless acquisition module, a storage module, a display module, a wireless transmission module and a power supply module. The wireless transmission module transmits the humiture data of a grain bin collected by the humiture sensor and the grain temperature data collected by the interface module and the wireless acquisition module to a host computer in a wireless mode. The hand-held terminal can employ a wired mode to obtain the condition of stored grain data which requires measurement and control, and can employ a wireless sensor network transmission mode to obtain the condition of stored grain data, the usage scope of the hand-held terminal is enlarged, and the service life of the hand-held terminal is increased; a TD-LTE technology and the host computer are used for data transmission, so that the hand-held terminal has the advantages of fast transmission rate, anti-multipath interference, flexible supporting of different bandwidth, and is very suitable for wireless transmission and reception of mass data information between the hand-held terminal and the host computer.

Description

technical field [0001] The invention relates to a hand-held terminal, in particular to a hand-held terminal used for collecting and transmitting grain situation data. Background technique [0002] During the storage of grain in the granary, it is necessary to measure and control the grain data such as the temperature and humidity of the granary and the temperature of the grain pile to avoid mold and deterioration of the grain during storage. The existing technology usually uses wired communication to measure and control the temperature and humidity of the granary and the temperature of the grain pile. For example, the layout of the field bus and the layout of the distributed control bus are used. A large number of temperature measurement cables are arranged, and the installation and disassembly are complicated; at the same time, the wired communication method is also easily affected by the wire resistance and distributed capacitance, and the measurement error is relatively l...
