ABSTRACT
The broadcast tonic train signalling alarm apparatus inquires two parts by the alarm apparatus and the statistics to be composed, the alarm apparatus by the monolithic integrated circuit control, is responsible for the real-time monitor stereo sound, two groups tonic train signallings, if discovered stops broadcasts, records the date and the time immediately which stops broadcasts, information and so on time which the signal restores, and saves them in monolithic integrate d circuit interior E2PROM, once has the IC card insertion, then will store up in E2PROM stops broadcasts the information storage to embrace to IC, again will stop through the IC card broadcasts the information with to read the card input to the computer in, or directly will read the fetching by the computer through the RS-485 connection from the alarm apparatus place according to, Again by manages software to carry on the analysis to compile finally uses the report form the form to print. Manages software also to be allowed through the database handling dbh, function and so on realization inquiry, statistics. This article tries from following several aspects to carry on the elaboration to this alarm apparatus design performance history:
1st, question proposing, briefly explained how background develops this system under.
2nd, this newspaper system design thought.
3rd, each part of more detailed flows, procedure statement.
4th, development method brief elaboration.
