Problems solved by technology

At present, some local specialty fish are usually bred in local rivers, but with the increasing demand of people, the wild quantity is far from meeting people's daily needs, which requires artificial breeding
However, after wild fish are transferred to artificial breeding, artificial farms often cannot be cultivated. The reason is that artificial breeding cannot meet the growth environment of fish; for data collection
Due to the need to collect data in water and on the water surface, data transmission, sensor maintenance, and installation and fixing are all troublesome and complicated
Most of the time, it cannot replace manual data collection, which leads to low labor efficiency, poor real-time data, and inability to detect and collect all-weather

Embodiment Construction

[0025] The specific implementation of the invention will be further described below in conjunction with the accompanying drawings.

[0026] Such as figure 1 As shown, a multi-point synchronous precise timing data acquisition system includes multiple data acquisition units 3 , ZigBee coordinator 2 and PC 1 .

[0027] The data collection unit 3 includes a fixing component 4 , a power supply component 5 and a data collection component 5 . The fixed assembly 4 includes a fixed plunger 7, a lower seal 8 and an upper seal 9. One end of the fixed plunger 7 is spike-shaped, and the other end is used to knock the fixed plunger 7 so that the spiked end of the fixed plunger 7 is inserted into the ground. The lower seal 8 is a waterproof sealing glass layer and is fixed around the middle and upper circumference of the fixed insertion rod 7 , and a sealing layer 10 is formed between the lower seal 8 and the fixed insertion rod 7 . The upper sealing part 9 is a sealed waterproof casing, w...

Abstract

The invention discloses a multipoint synchronous, precise and timed data acquisition system, and belongs to the technical field of data synchronous acquisition. A LabVIEW based multipoint synchronous, precise and timed data acquisition system comprises the steps of building a virtual data acquisition instrument by regarding LabVIEW of NI Company as development software and combining with a computer and a ZigBee network; realizing transparent transmission of multipoint data by utilizing a wireless transmission function of a ZigBee network; communicating with the computer by the ZigBee network through a serial port; and finally analyzing, processing, displaying and storing the acquired data by applying an application program developed by LabVIEW in the computer. Acquisition and transmission of multipoint transmission in aquaculture is realized; and normal work of a sensor is ensured.

Description

technical field [0001] The invention relates to the technical field of data synchronous acquisition, in particular to a multi-point synchronous and precise timing data acquisition system. Background technique [0002] With the rapid development of computer technology, VLSI technology and communication technology, traditional stand-alone instruments are far from being able to meet the requirements of large quantities and high-quality information collection. New testing domains continue to develop and evolve as various disciplines intersect. A measurement and control system with computer as the core control has been produced, and each unit in the system is interconnected through various buses, and then the information is transmitted. Especially in industries such as petroleum, electric power, water conservancy, water supply, gas and other distributed operations that require remote precise timing measurement and control, the distance between different measurement sites is larg...
