Non-contact automatic reading and writing system for dangerous chemical identity information

The invention relates to a non-contact automatic reading and writing system and method for dangerous chemical identity information, and belongs to the technical field of dangerous chemical identity information reading. The system comprises a main control circuit unit, a wireless autonomous sensing unit, a communication interface unit and an antenna; the main control circuit unit is connected withthe wireless autonomous sensing unit and the communication interface circuit unit. The wireless autonomous sensing unit is also connected with an antenna; the system solves the problems that an existing dangerous chemical identity information supervision system cannot directly reflect potential safety hazards existing in the dynamic circulation characteristics in the dangerous chemical circulationstage, errors are likely to happen when dangerous chemical identity information is managed manually, and efficiency is low. The invention is applied to warehouse-in and warehouse-out management of dangerous chemical identity
