Abstract

The invention discloses a data processing method. The method comprises the steps of receiving current to-be-recorded data uploaded by a lower computer through an upper computer; comparing the current to-be-recorded data with stored record data preloaded in a caching queue of a data caching library; when the same record data is found in the caching queue, returning recording success information; when the same record data is not found in the caching queue, storing the current to-be-recorded data in a database, and returning the recording success information; obtaining the current to-be-recorded data needed to be uploaded to the upper computer by the lower computer; receiving the recording success information returned by the upper computer; and when the current to-be-recorded data is all uploaded, deleting the current to-be-recorded data stored in the lower computer. According to the method, the consumption of database performance of the upper computer is reduced, and the problem of repeated recorded data of the upper computer is solved. In addition, the invention provides a data processing apparatus, a data interaction method and a data interaction apparatus with the abovementioned technical advantages.

Description

technical field [0001] The invention relates to the technical field of data interaction between upper and lower computers, in particular to a data processing method and a corresponding device, a data interaction method and a corresponding device. Background technique [0002] The data interaction mechanism between the upper computer and the lower computer is widely used in security equipment. The upper computer refers to the computer that can directly issue control commands, generally PC / host computer / master computer / upper computer, and various signal changes (hydraulic pressure, water level, temperature, etc.) are displayed on the screen. The lower computer is a computer that directly controls the device to obtain the status of the device, usually a PLC / single chip microcomputer / slave computer / lower computer and the like. The command issued by the upper computer is first given to the lower computer, and then the lower computer interprets the command into a corresponding ti...
