Abstract
In order to overcome the problem of low tolerance in strong electromagnetic pulse and over-voltage circuitance,the author have done the experiments of over-voltage tolerance on communication interface device of Mine Safety Monitoring System ,using a standard mold by designing Test circuit of transmission signal and overvoltage suffertibility on netface communication interface.Then desiged Surge protection circuit of RS232 and RS432 interface by compareing the The greatest tolerence error-access capacitance caculated values and measured values.
