Sensor Data Processing System

Abstract

The present invention relates to a sensor data processing system, comprising a host computer, PLC, sensors, address mapping table, processor and a memory storing computer programs, the host computer is connected to at least one PLC in communication, and the PLC is connected to at least one device, each A device is connected to at least one sensor; each device is provided with a corresponding data storage area in the connected PLC, including the first data bit, the second data bit and at least one sensor data bit, and each data bit corresponds to a PLC address ;When the first data bit is set to 0, it means that the sensor data corresponding to the data storage area has not been collected; when it is set to 1, it means that the collection is completed; The storage is completed. When it is set to 1, it means that the storage is completed; the address mapping table is used to store the PLC address corresponding to the device id and the corresponding data storage area. The invention can store target sensor data quickly and accurately.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a sensor data processing system. Background technique [0002] In the production process of vehicles and other products, it is usually necessary to store some important sensor data generated on the production line for subsequent assembly process call or quality traceability. In the prior art, a single-threaded or multi-threaded method is used to store target sensor data. However, for a single-threaded storage method, if the number of target sensors is large, the data processing speed will be slow and the storage efficiency will be low. For the multi-threaded storage method, usually multiple target sensor data are stored in parallel, which leads to complex storage procedures and a large amount of calculation. In addition, regardless of the existing single-threaded or multi-threaded methods, it is impossible to know in real time whether each target sensor data has data los...

Problems solved by technology

In the prior art, the target sensor data is stored in a single-threaded or multi-threaded manner. However, for the single-threaded storage method, if the number of target sensors is large, the data processing speed will be slow and the storage efficiency will be low.

For the multi-threaded storage method, usually multiple target sensor data are stored in parallel, which leads to complex storage procedures and a large amount of calculation

In addition, regardless of the existing single-threaded or multi-threaded methods, it is impossible to know in real time whether each target sensor data has data loss or not, and whether the storage is successful, and continuous collection of target sensor data may cause the next data to overwrite the previous data, which is easy cause data storage error
