Multi-source constant value checking and comparing method

The invention discloses a multi-source constant value checking and comparing method, which comprises the following steps of: identifying a paper constant value sheet, acquiring identified constant value data, and extracting Bluetooth constant value data of a device in a wireless mode; establishing a dictionary database according to a constant value specification; unifying the unit of each constant value in the identification constant value data and the Bluetooth constant value data; modifying the constant value name of the identification constant value data and the constant value name of the Bluetooth constant value data according to the dictionary database; correcting and identifying the constant value of the constant value data according to the dictionary database; and performing association check on the constant value name in the identified constant value data and the constant value name in the Bluetooth constant value data. According to the method and the system, the fixed values are obtained in various m
