Title:
TEMPERATURE-SENSING FIRE DETECTION CABLE
Document Type and Number:
WIPO Patent Application WO/2021/227454
Kind Code:
A1
Abstract:
A temperature-sensing fire detection cable, comprising two conductors (1), wherein insulating layers (2) are arranged outside the conductors (1); an insulating tape (4) is connected between the insulating layers (2); an outer sheath (8) is arranged outside the insulating layers (2) and the insulating tape (4); a plurality of detection modules are arranged at intervals on the insulating tape (4); the detection modules are electrically connected to the conductors (1); the detection modules each comprise a temperature sensing element (9) and a temperature control chip (11); the temperature sensing elements (9) measure the temperature and transmit measured temperature data to the temperature control chips (11); the temperature control chips (11) process the received temperature data and transmit the processed temperature data by means of connecting points (13) and the conductors (1); the detection modules are connected in series by means of a fuse wire (7); the temperature control chips (11) monitor, in real time, the current, flowing through the detection modules, of the fuse wire (7), so as to obtain switching-on and switching-off signals of the current of the fuse wire (7); and the temperature control chips (11) process the received switching-on and switching-off signals, and transmit the processed switching-on and switching-off signals by means of the connecting points (13) and the conductors (1). The cable has the functions of a temperature measurement alarm, locating, electric energy supply and signal transmission, self-protection, etc.
