In one embodiment, as shown in FIG. 1, a method for indicating a fire escape is provided, comprising the steps of:
s120: and acquiring the state information of each smoke sensor in the area.
The smoke sensor is powered by a bus, a plurality of smoke sensors can be connected to the bus, the smoke sensors are networked with the fire alarm controller and communicate to form an alarm system, no sound is generated on site during alarm, and the host machine has acousto-optic prompt. The smoke detector is divided into address coding and non-address coding. The state information of the smoke sensor comprises the concentration of smoke and the time for triggering the smoke sensor by the smoke, and the concentration of the smoke and the time for triggering the smoke sensor by the smoke can be used for judging the spreading condition of the fire.
S140: and determining the spreading condition of the fire according to the state information of each smoke sensor.
A fire may be considered to have occurred here when the smoke sensor detects that the concentration of smoke reaches a certain threshold. Wherein, the threshold value can be set according to the requirement. Furthermore, the fire spreading condition can be judged according to the smoke concentration, and the fire condition is more serious in the area with higher smoke concentration. When the smoke sensor is triggered by smoke, the triggering time can be recorded, the smoke triggering time can be used for judging the spreading condition of the fire, and the spreading direction of the fire can be judged according to the triggering sequence.
S160: indicating the escaping direction of the fire according to the spreading condition of the fire.
The fire spreading condition comprises a fire spreading direction and a fire degree, and the reverse direction of the fire spreading direction and/or the lighter side of the fire are determined as the fire escaping direction according to the fire spreading direction and the fire degree.
According to the method for indicating fire escape, the state information of each smoke sensor in the area is acquired in real time, the spreading condition of the fire is determined according to the state information of each smoke sensor, the direction of fire escape is indicated according to the spreading condition of the fire, the condition that escape personnel escape to the fire area is avoided, and the escape personnel can escape accurately according to the indication.
In one embodiment, as shown in fig. 2, S160 includes:
s220: determining the spreading direction of the fire according to the spreading condition of the fire;
s240: determining the escape direction to which each escape indicator lamp in the area needs to point according to the spreading direction of the fire;
s260: and outputting a control instruction to each escape indicating lamp according to the escape direction to which each escape indicating lamp needs to point, wherein the control instruction is used for controlling each escape indicating lamp to indicate the escape direction to which each escape indicating lamp needs to point.
After the spreading direction of a fire disaster is determined, the server can acquire the identity of each escape indicator lamp in the area, each escape indicator lamp has a unique identity, and the identity of each escape indicator lamp and the corresponding position of the corresponding escape indicator lamp have a relation which can be acquired based on the distribution setting data of the escape indicator lamps in the history record, so that the positions of the escape indicator lamps can be determined according to the identity of the escape indicator lamps. The server determines the escape direction to which the escape indicator lamp needs to point according to the position of the escape indicator lamp and the spreading direction of the fire, outputs a control instruction to the escape indicator lamp with the identity identification, and controls the escape indicator lamp to indicate the escape direction to which the escape indicator lamp needs to point.
According to the spreading condition of the fire, the spreading direction of the fire is determined, the place where the dense smoke spreads is known, the escape direction to which each escape indicator lamp needs to point in the area is determined, then, a control instruction is output to each escape indicator lamp according to the escape direction to which each escape indicator lamp needs to point, and each escape indicator lamp is controlled to indicate the escape direction to which the escape indicator lamp needs to point. For example, when a fire disaster occurs, according to the spreading condition of the fire disaster, it is determined that the escape passage on the left side of one escape indicator lamp is to be spread by dense smoke, at this time, it is determined that the right side of the escape indicator lamp is the escape direction to which each escape indicator lamp needs to point, a control instruction is output to the escape indicator lamp, and the escape indicator lamp is controlled to only light the indicating arrow on the right side, so that escape of evacuees to a dense smoke region is avoided, and the escape probability is further improved. When the fire spreading direction is determined to be the positive west direction according to the fire spreading condition, the dense smoke spreads towards the positive west direction, the positive east direction opposite to the positive west direction can be determined to be the escape direction to which each escape indicator lamp in the area needs to point at the moment, the server outputs a control instruction to each escape indicator lamp according to the fact that each escape indicator lamp needs to point at the positive east direction, and each escape indicator lamp is controlled to indicate the escape direction to which the server needs to point, namely the positive east direction opposite to the fire spreading direction.

When the time is longer when the conflagration takes place, whole floor has all been filled with dense cigarette, and at this moment, the pilot arrow of the direction of the smoke transducer that the control pilot lamp of fleing only lights towards the trigger time late, and the later that this ascending dense cigarette of direction stretchs, the intensity of a fire is less, and the condition of fleing from this direction, the probability of fleing is greater than another direction. For example, the four indication directions A, B, C, D of the escape indication lamp are all the spreading directions of a fire, the four indication directions of the escape indication lamp all point to smoke sensors, the trigger sequences of the smoke sensors are obtained and sequenced, if the sequence of the trigger time is ABCD, that is, the smoke sensor pointed by the direction D is triggered at the latest, the fire in the direction D is considered to be small, and the direction D is selected as the escape direction to which each escape indication lamp in the area needs to point.

An escape path can be generated according to the escape direction to which each escape indicator lamp needs to point, the end of the escape path is a safety exit, and when a user reaches the safety exit which does not belong to a fire area, the user can safely escape. The method comprises the steps of obtaining position information of a safety exit corresponding to an escape direction to which each escape indicator lamp needs to point, obtaining state information of a smoke sensor at the safety exit, determining the fire spreading condition of each safety exit according to the state information of the smoke sensor at the safety exit, and outputting a control instruction to each escape indicator lamp to point to each safety exit position area when the safety exit position area does not belong to a fire area. If the safe exit position area belongs to the fire area, the server can output a control instruction to each escape indicating lamp to point to other safe exit position areas. Furthermore, an induction switch is preset at the front section of the escape indicator light in the position area of the safety exit, when a person passes through the position area of the safety exit, the server can acquire the position information of the safety exit through the induction switch preset at the front end of the escape indicator light and output a control instruction to the escape indicator light to point to the safety exit.
