In one embodiment, as shown in fig. 2, a fire information control method is provided, which is described by taking the example of applying the method to the fire information control device in fig. 1, and includes the following steps:
The monitoring parameters refer to real-time monitoring data of external monitoring equipment, such as a smoke concentration value acquired by a smoke sensor and a temperature value acquired by a temperature sensor.

And obtaining the state of each fire fighting channel according to the monitoring parameters, for example, when the monitoring parameters of a certain fire fighting channel are greater than a preset threshold value, the state of the fire fighting channel is a dangerous state, otherwise, the state is a safe state. For example, in the case of a fire, the most fatal are high temperature and harmful gases in the smoke due to a big fire. The harmful gas is carbon monoxide generally, and the concentration of the harmful gas is too high, so that people are easily unconscious and suffocated, and casualties are caused. In view of this, in each fire fighting tunnel, a carbon monoxide sensor and a temperature sensor may be provided for detecting the concentration of carbon monoxide and the temperature of the fire fighting tunnel, respectively.

The preset threshold value of the temperature parameter can be set according to actual conditions, and can be set to 70 ℃ for example. If the temperature exceeds the preset threshold value, the temperature in the fire fighting channel exceeds the human body bearing range, generally, the situation of large fire or the situation of overhigh smoke temperature is shown. The preset threshold value of the carbon monoxide concentration parameter can also be set according to the actual condition, and according to statistics, when the carbon monoxide content in the air exceeds 1.3%, a person inhales two or three breath and loses consciousness, and the person breathes for 13 minutes to cause death. Specifically, the preset threshold value of the carbon monoxide concentration parameter may be set to 1.3%, that is, 1.3% of the amount of carbon monoxide.

The larger the void ratio of the fire fighting access in the safe state is, the smaller the crowding degree of the access is, the more convenient the rapid evacuation of people is, and the personnel evacuation efficiency is improved. It can be understood that, in an actual scene, the number of the determined fire fighting access in the safe state is not fixed, and may be one or more, if the number of the determined fire fighting access in the safe state is one, the indication direction of the current fire fighting access can be directly switched to the fire fighting access in the safe state, and the calculation of the void ratio is not performed, so that the operation efficiency of the system is improved. The method comprises the steps of determining the fire fighting channel in the safety state with the maximum void ratio by calculating the void ratio of the fire fighting channel in each safety state, and switching the indicating direction of an indicating lamp corresponding to the fire fighting channel in the dangerous state to the fire fighting channel indicating the safety state.

Then, the indication direction of the indicator light corresponding to the fire fighting access is switched to the fire fighting access indicating the nearest safety state, for example, the indication direction of the indicator light corresponding to the fire fighting access a is switched to the indication fire fighting access C. The indication direction of the indication lamp of the fire fighting access indicating the dangerous state is switched to the fire fighting access indicating the nearest safe state, so that the dangerous escape path can be reduced, and the escape efficiency is improved.

The fire-fighting indicator Light can be an LED (Light Emitting Diode) dot matrix screen, which is composed of a plurality of LED lamp beads and displays characters or pictures by lighting and extinguishing the lamp beads. Each lamp bead is connected to a power supply through a switch, and the switch is connected with the fire-fighting information control device. The fire-fighting indicator lamp lights different lamp beads through control to display different information according to the control instruction. Taking a pulse width modulation method as an example, each lamp bead can control the lighting time through an independent pulse width modulator, and in a period of repeated lighting, the light pulse width (i.e. duty ratio) is changed to adjust the brightness.
The fire-fighting indicator light can be respectively controlled to display different brightness by changing the pulse width, under the normal condition, the minimum brightness of the surface of a single LED is not less than 50cd/m2, and the maximum brightness is not more than 300cd/m 2; in a sudden situation, the minimum brightness of the surface of the single LED is not less than 500cd/m2, and the maximum brightness is not more than 1000cd/m 2.
In the second method, for example, the color of the indicator light is green under normal conditions, and the color of the indicator light can be changed into yellow or red to attract people's attention after the indication direction of the indicator light is switched. In the third mode, the indicator lamp is controlled to flash at a certain frequency to attract people's attention. It is understood that the above three highlighting means can be used alone or in combination. But may also be highlighted in other ways in other embodiments of the application, which are not listed here.
