A framework for centrally controlling a plurality of building automation systems. The architecture and method automates a plurality of existing and new building automation systems comprising access control, HVAC, fire safety etc. in such a way that the plurality of building automation systems can be monitored and controlled from a central dashboard. The central dashboard effectively monitors, takes right decisions and remotely controls the buildings across the globe from a centralized location.

The invention discloses an explosion-proof and fire protection emergency mark lamp. The explosion-proof and fire protection emergency mark lamp comprises a face cover, an indication mark transparent piece arranged on the face cover, a shell matched with the face cover, a sealing ring arranged at the matched position of the face cover and the shell, a control rod, a gland nut, an O-shaped sealing ring and padding arranged at the matched position of the gland nut and the shell, the control rod and the gland nut are arranged on the side wall of the shell, and the O-shaped sealing ring is arranged at the matched position of the control rod and the shell. The adjoining face of the face cover and the shell is a plane explosion-proof face. The adjoining face of the control rod and the side wall of the shell is a cylindrical explosion-proof face. The adjoining face of the gland nut and the side wall of the shell is a thread explosion-proof face. An independent and sealed explosion-proof cavity is formed by the face cover, the indication mark transparent piece, the shell, the sealing ring, the control rod, the O-shaped sealing ring, the gland nut and the padding. The explosion-proof and fire protection emergency mark lamp further comprises a reflector provided with a folded edge, and an LED light source plate is installed on the folded edge. The lamp can effectively solve the problem of the fire protection emergency line indication when a dangerous zone with the explosion-proof requirement is powered off, and the requirements for national fire protection safety and explosion-proof safety are met.

The invention relates to a fire extinguishing device. The fire extinguishing device comprises: a housing; a top cover, the top cover is fixed on the top of the housing, and there is a buffer cavity in the top cover; a porous member is fixed on the top Covered, accommodated in the housing, and the combustion chamber formed by the porous member and the top cover communicates with the buffer chamber; the gas generated by the combustion chamber enters the buffer chamber during operation, reducing recoil . The fire extinguishing device further includes: an initiator fixed on the top cover and accommodated in the cavity formed by the porous member and the top cover; a baffle plate sealed to the opening at the bottom of the casing. The buffer chamber communicates with the combustion chamber through the Laval hole. The buffer cavity is an annular cavity or several buffer cavities arranged concentrically in an annular shape or several buffer cavities arranged along the circumference. Therefore, the fire extinguishing device of the present invention utilizes the buffer chamber of the top cover to realize a slight recoil force, so the safety of use of the fire extinguishing device is improved, and the fire extinguishing ability can be further improved.

The invention discloses a fire safety monitoring system capable of starting emergency lighting, which comprises a system master control terminal, wherein one end of the system master control terminal is electrically connected with a circuit monitoring terminal, and one end of the system master control terminal is electrically connected with a circuit control terminal. According to the invention, firstly, a sequential flashing marquee program is programmed through a programming control module, when an emergency lighting lamp is installed, the emergency lighting lamp is installed according to a specific circuit, the sequential flashing marquee program is programmed to select the flashing sequence according to the lamp installation position, programming is carried out in the direction from the interior to the fire fighting access, when a fire disaster occurs, the system master control terminal controls the lighting control terminal to start the emergency lighting system, a programming operation module in the emergency lighting system operates the sequential flashing system, the emergency lighting system starts emergency lighting equipment, and sequential flashing is carried out in the direction from the interior to the fire fighting access, so that an effective prompting effect can be achieved, and the problem that when a fire breaks out, people cannot find the direction is prevented.

The invention discloses a clothing test assist device which comprises a machine body, a handle is fixedly arranged on the right side face of the machine body, an operation cavity penetrating front and back is formed in the handle, a first hydraulic cavity is formed in the machine body, hydraulic oil is arranged in the first hydraulic cavity, and a first piston is connected in the first hydraulic cavity in a left-right sliding mode. The right side surface of the hydraulic cavity I is internally provided with a through hole I which rightwards penetrates into the operation cavity. The device is small and exquisite in shape and convenient to carry, so that the device is suitable for real-time assault inspection, and the detection result tends to be real. The toughness and the stretching limit of the clothes can be detected, the quality of the clothes can be more visually determined through the detection item, the ignition point of the clothes can be measured, and the purity of materials used by the clothes can be preliminarily determined through the detection item; during ignition point detection, only a small piece of cloth separated from the whole clothing is ignited, and fire safety is guaranteed.
