Passenger train overload monitored control system based on singlechip

Passenger train overload monitored control system based on singlechip is including singlechip, pressure sensor, speaker, display screen. Relay, speaker, display screen are connected with the monolithic is electromechanical respectively, infrared photoelectric sensor is connected with the singlechip after connecting count processing circuit, pressure sensor is connected with the singlechip after connecting AD conversion chip. The utility model discloses can monitor the interior number of passenger of passenger train automatically to show in real time through liquid crystal display. When the number is greater than predetermined value appearance overload in the passenger train, system acousto -optic warning, the starting drive that the passenger train was closed through the relay to the while stops the passenger train operation, when the number is lighter than the predetermined value in the passenger train, remove acousto -optic warning and starting drive's locking, but passenger train normal operating can signi
