Referring to fig. 1, a fire early warning apparatus includes:

a sensor assembly 10, the sensor assembly 10 comprising a carbon monoxide sensor 11, a carbon dioxide sensor 12, a smoke concentration sensor 13 and a temperature sensor 14;

a control hub 20, the control hub 20 being electrically connected to the sensor assembly 10;

a terminal alarm connected to the control hub 20.

By electrically connecting the control center 20 with the sensor assembly 10, the sensor assembly 10 comprises a carbon monoxide sensor 11, a carbon dioxide sensor 12, a smoke concentration sensor 13 and a temperature sensor 14, because in the early stage of a fire, a certain amount of carbon monoxide can be generated due to insufficient combustion, the carbon monoxide sensor 11 is used for measuring the content of the carbon monoxide, when the carbon monoxide is found to be increased rapidly or any data of the carbon dioxide, the temperature or the smoke concentration is found to be changed abnormally, the carbon monoxide is analyzed by the control center 20 in time, the carbon monoxide is used as leading data, and the carbon dioxide, the temperature and the smoke concentration are used as instant data for comparison and analysis, so that whether the fire breaks out can be analyzed earlier, and an alarm is given by a terminal alarm in time, so that a user has more sufficient time to escape, the fire extinguishing time is shorter, and the user loss is lower.

Because the existing indoor fire early warning equipment belongs to an instant warning mode, namely, if an indoor fire occurs, an alarm sounds indoors, the existing problem is that if an outdoor fire occurs, and a user is in an indoor room, the situation that the alarm does not hear may occur, and in the public early warning equipment, a plurality of sensors are connected in parallel in a set of circuits, so that when individual sensors fail, a control center can continuously receive a fire false alarm signal, an operator needs to close all the sensors in the set of circuits to avoid interference and wait for maintenance of a manufacturer, the maintenance duration usually lasts for months, so that the fire early warning equipment is in a failure state during maintenance, in fact, the control center basically does not receive the alarm signal at the initial stage of the fire in many domestic large public places, and comprehensively, preferably, the control center 20 is electrically connected with a wireless transmission module 30, the terminal alarm is provided with a first wireless receiving module in wireless connection with the wireless transmission module 30, and the first wireless receiving module and the wireless transmission module 30 enable the terminal alarm to be located beside a user in a manner of being separated from the limit of a power line, so that the user can conveniently know fire information, and the sensor assembly 10 and the control center 20 can be independently disconnected when a certain sensor assembly 10 is damaged without disconnecting the whole circuit.

Further, preferably, the terminal alarm is an audible and visual alarm 21.

Further optimized, the terminal alarm is preferably a mobile terminal 22 with a display device. In view of the breadth of alarm propagation, it is preferable that the terminal alarm includes both an audible and visual alarm 21 and a mobile terminal 22 with a display device.

Further, for faster fire fighting, it is preferable that the control center 20 is connected to a server 40 and a numerical control display 50 electrically connected to the server 40. Therefore, signals of a plurality of sensor assemblies 10 can be concentrated on one server 40, so that monitoring is facilitated for a user, and meanwhile, in order to avoid influence caused by a line, a second wireless receiving module in wireless connection with the wireless transmission module 30 is preferably arranged on the server 40, so that a human guarantee is added under the condition that a terminal alarm is provided.

In order to prevent the sensor assembly 10 from being out of operation due to power failure in case of fire, it is preferable that the sensor assembly 10 is provided with a backup power supply.

Further improve, in order to put out or reduce the influence of conflagration in time when the conflagration takes place, preferably control maincenter 20 electric connection has control switch, the last dry powder fire suppression jar of installing of control switch, when the conflagration takes place, control maincenter 20 control switch opens the dry powder fire suppression jar of relevant position to carry out the conflagration suppression earlier when the rescue personnel have not arrived, thereby reduce the speed that the conflagration propagated.

Further improve, because the initial stage takes place for the conflagration, carbon monoxide, carbon dioxide and the smog that the burning produced flow slowly, lead to carbon monoxide, carbon dioxide and smog to flow to having the time lag when being responded to by sensor assembly 10, in order to reduce the time lag, preferably still include a sleeve 60, install the fan in the sleeve 60, sensor assembly 10 set up in the sleeve 60, install sleeve 60 on the wall during the installation, through the drainage effect of fan, accelerate indoor air circulation to thereby carbon monoxide, carbon dioxide and the smog that enable the burning to produce can be faster circulate to be responded to by sensor assembly 10 in the sleeve 60, and then further reduced the early warning time lag, make the conflagration can be more quickly discovered, thereby reduce masses' loss.

The above is only the preferred embodiment of the present invention, not limiting the patent scope of the present invention, all of which are under the concept of the present invention, the equivalent structure transformation made by the contents of the specification and the drawings is utilized, or the direct or indirect application is included in other related technical fields in the patent protection scope of the present invention.
