1. a safety system, comprising:

  • Control panel, is positioned at protected facility place;

    Multiple transducer;

    WithCentral monitoring station, described central monitoring station is connected to described control panel through the first and second communication paths, and the first and second paths are connected in parallel between described panel and described central monitoring station;

    Described multiple sensor electrical is coupled to described control panel, and it reports invasion in described facility or emergency usually;

    The primary communication device of the first communication path, for sending data to described central monitoring station by the Internet from described control panel and receiving data by the Internet from described central monitoring station at described control panel;

    With the auxiliary means of communication in second communication path;

    for sending data to central monitoring station from described control panel and receiving data at described control panel from described central monitoring station so that when utilize described primary communication device to carry out communication becomes unavailable time be used as spare communication;

    Also comprise;

    Be positioned at control panel or be directly coupled to the Internet intrusion detection device of control panel, each of described the Internet intrusion detection device and described first and second communication paths is connected in series, wherein said the Internet intrusion detection device is directly coupled to described primary communication device through described first communication path, and described the Internet intrusion detection device is directly coupled to described auxiliary means of communication through described second communication path, described the Internet intrusion detection device monitors the message communicating amount of described control panel and the message communicating amount detecting monitoring in described primary communication device is carried out the invasion of the Internet attack, wherein said intrusion detection device is when described invasion being detected, forbid described primary communication device, even if enable described auxiliary means of communication and communication be switched to described auxiliary means of communication so that when the invasion of attacking in the Internet occurs, also the communication between described control panel and described central monitoring station is kept through described auxiliary means of communication, andWhen the characteristic scalar of wherein attacking when newtype is found, described intrusion detection device can be upgraded by described central monitoring station.
