This utility model discloses a multispectral flame detection camera, including a front shell and a rear shell, which are connected by screws. A low-voltage circuit board and a high-voltage circuit board are disposed between the front and rear shells. The low-voltage circuit board and the high-voltage circuit board are connected by screws, and a screw sleeve is sleeved on the outside of the screw, forming a gap between the low-voltage circuit board and the high-voltage circuit board. A night vision filter switcher is installed on the low-voltage circuit board, and a visible light receiver is installed on the night vision filter switcher. A through hole is opened on the high-voltage circuit board, through which the visible light receiver extends to the outside of the high-voltage circuit board. This utility model, by isolating the high and low voltage circuits, ensures that they do not interfere with each other, significantly improving the stability of the application during use. At the same time, through acoustic and optical multimodal sensing, it achieves high-precision flame detection and rapid response in complex environments.

The utility model discloses an explosion-proof audible and visual alarm, which comprises a bus power supply module, an audible and visual alarm module, a first bus power supply module interface, a second bus power supply module interface, a third bus power supply module interface, a fourth bus power supply module interface, a fifth bus power supply module interface, a sixth bus power supply module interface, a fifth bus power supply module interface and a sixth bus power supply module interface, the first main controller module U2 receives and feeds back communication signals and is connected and powered by a fire-fighting two-bus power supply, the first 24V communication isolation module comprises a magnetic latching relay, and a control power supply 24V + and a fire-fighting two-bus form a power supply system or two independent power supply systems; the 24DVC voltage output end connected with the first power system clutch module receives signals of the first 24V communication isolation module or the first main controller module U and outputs the signals to the buzzer drive circuit to give out warning sound. According to the explosion-proof audible and visual alarm of the utility model, two-wire and four-wire working modes are adaptively switched.

The utility model discloses a multifunctional connecting line suitable for automatic production, including wire rod, first connector and accomodating piece, the wire rod includes main road section and a plurality of vice road sections, and the one end of every vice road section is connected fixedly with second connector, and every vice road section includes the sheath, and the sheath includes insulating sleeve, heat -resistant layer, reinforcing layer, metal shielding layer and insulating layer. Through setting accomodating piece on one vice road section, the rest vice road sections are fixed in fixed groove, remove accomodating piece and make all vice road sections align, so that the automatic equipment can directly snatch accomodating piece and make the one end of every vice road section stretch into injection mold, and the insulating body of second connector is formed by injection molding, so that the connecting line is suitable for automatic production, and the metal shielding layer is coated on the surface of reinforcing layer, when the connector connects different equipment simultaneously, even if the distance between each vice road section is very close, signal interference does not occur between each other, and the normal work of connecting line is not affected.
