A Massive Sensor Data Acquisition System

Abstract

The invention relates to a massive sensor data collection system used for location control of a car model in a sand table. The system comprises a sensor, an isolator, at least four complex programmable logic devices, a controller and an upper computer. The output ends of the complex programmable logic devices are connected with an extension bus of the controller. Due to the fact that massive magnetic location devices are required to be collected, the plurality of complex programmable logic devices are connected into the parallel extension bus of a common single chip microcomputer, the problems caused by the fact that pins are not enough and the single chip microcomputer is poor in load capability are solved, location information can be effectively processed, and simultaneous reading and processing of massive sensors are achieved.

Description

technical field [0001] The invention belongs to the field of sensor data collection, in particular to the field of massive sensor data collection. Background technique [0002] There are roughly two types of domestic sand table technical solutions with moving models. One is sand tables with fixed tracks, and most of them are moving models such as trains that depend on fixed tracks. The second common one is to place a magnet under the road on the sand table, and use the attraction of the magnet to drive the movement of the car model on the surface of the sand table. These two solutions also have many shortcomings. The road network is too simple, the model cannot move freely, and it cannot support a large number of models to move at the same time. Therefore, another solution needs to be adopted to solve the above problems. [0003] Because the distance between the positioning grids of the car models traveling on the sand table is much smaller than the positioning accuracy of...

Problems solved by technology

Therefore, it is necessary to adopt another solution to solve the above-mentioned shortcomings, but due to the need to collect and process a large number of sensors, each sensor needs to be connected to the controller, and because the number of pins of an ordinary single-chip microcomputer is not enough , so there is an urgent need for a massive sensor data acquisition system
