Data checking device and control method thereof

Abstract

The invention provides a data checking device and a control method thereof, and relates to the technical field of computer data processing. The data checking device includes a first processor, a second processor, and a third processor. The first processor is configured to receive first to-be-checked data obtained by pre-acquiring a preset object. The second processor is configured to receive second to-be-checked data obtained by pre-acquiring the preset object. The third processor is configured to compare the same type of sub-data in the first to-be-checked data and the second to-be-checked data, and generate a check result. The data checking device receives the pre-acquired to-be-checked data by the first processor and the second processor, and checks the to-be-checked data by the third processor, which, on the one hand, helps to reduce the service pressure of respective processors and timely obtain the checking results, on the other hand, helps to avoid potential safety hazards caused by delayed checking results.

Description

technical field [0001] The present invention relates to the technical field of computer data processing, in particular, to a data checking device and a control method thereof. Background technique [0002] In the railway industry, the train operation control system is the main equipment to control the operation of the train, ensure the safety of railway operation, and improve the transportation efficiency. However, the corresponding devices (such as speed sensors) that collect train-related data (such as running speed) are prone to failure after long-term operation, resulting in inaccurate data collected, or other unexpected failures of the corresponding devices. data is incorrect. In the prior art, two groups of modules for collecting data are usually set up, and the same processor obtains the corresponding data from the modules and checks the data. The workload of the processor is large, and when checking a large amount of data, delays are prone to occur. In this case, t...

However, the corresponding devices (such as speed sensors) that collect train-related data (such as running speed) are prone to failure after a long period of operation, resulting in inaccurate data collected, or the corresponding devices may cause a collection failure due to other unexpected failures. the data is incorrect

In the prior art, two sets of data collection modules are usually set up, and the same processor obtains the corresponding data from the modules and checks the data. The workload of the processor is large, and delays are prone to occur when checking a large amount of data. Due to the situation, the collected data cannot be verified in time, which is prone to safety hazards
