Abstract

The invention discloses a modular data logger based on Zigbee wireless communication and an operating method thereof, wherein a host module, a master node module and a plurality of salve node modules jointly form a star wireless network topological structure. The operating method comprises the following steps: the host module is set to configure functions of the salve node modules; the host module sends the set data information to the master node module; the master node module sends the set data information to the specified salve node modules through a first Zigbee wireless communication module and a transmitting and receiving antenna in a wireless transmission manner; after receiving the set data information, the salve node modules perform test configuration as requested, acquire and calculate signals of channels, and then sends a computing result to the master node module through a second Zigbee wireless communication module and the other transmitting and receiving antenna; and after receiving the computing result, the master node module stores the data in an EEPROM and then sends the data to the host module when the host module is idle. The invention realizes data acquisition modularization and convenient system expanding and updating, and requires no complicated wiring and power supply while establishing a system, thus achieving more reliable transmission.

Description

technical field [0001] The invention relates to a data recorder, in particular to a modular data recorder adopting wireless data transmission. Background technique [0002] At present, the traditional data recorder is mainly composed of two parts, a digital circuit board and an analog circuit board. These two parts are a whole circuit board structure, and the digital circuit board and the analog circuit board are connected by a communication cable. The defects are; 1. Function expansion is very inconvenient, and the entire circuit board often needs to be replaced when the function is upgraded; 2. The degree of modularization is not high, and the user needs to specify the number of channels when purchasing, which is very inconvenient for later upgrades and function additions; The sensor line needs to be extended very long during the distance test, resulting in a decrease in test accuracy and reliability. [0003] "Zigbee" is a new wireless network data communication technolo...
