Described 800M frequency range reception antenna is built-in aerial.

Described controller is conventional programmable controller, and model is M30622.

Described 800M Train Approaching early warning information receiver is conventional programmable module, and model is M30622.

Described housing is provided with the DLL (dynamic link library) that is electrically connected with controller.

The described part of controlling comprises: LCDs, conversation emission PTT button, channel knob, indicator light, operation keyboard, function keyboard, red and yellow early warning button that can started by press emission early warning information.

The utlity model has following advantage and effect: adopt such scheme, 800M Train Approaching early warning information receiving function and 400M Radio train dispatching commander communication function is united two into one, allow security protection person needn't carry simultaneously two intercoms and corresponding reserve battery, effectively reduce security protection person's heavy burden, alleviate its labour intensity, convenient operation on an intercom, can receive 800MHZ, 400MHZ frequency band signals simultaneously simultaneously.By the voice reading function, can carry out voice reading to work at present frequency and battery low-electricity quantity, allow the user can understand clear, easily the operating state of intercom, find the circuit dangerous situation the security protection personnel, know when Train Approaching is arranged by 800M Train Approaching early warning information receiver again this moment, can in time in time stop by safety precaution function notice approaching train, occur to avoid the train safe accident, automatically state is used in the record early warning simultaneously, is convenient to management.
