Description

Equipment for monitoring temperature and fire risk

Technical Field

The utility model relates to a control field, in particular to an equipment that is used for temperature and conflagration risk to monitor.

Background

A fire refers to a catastrophic combustion event that loses control over time or space. Among the various disasters, fire is one of the main disasters that threaten public safety and social development most often and most generally. In order to find out fire accidents in time, fire alarm systems are installed in a plurality of places, and the existing fire alarm systems can monitor abnormal data such as high temperature and smoke in time after a fire disaster happens through the arrangement and the application of sensors, so that an alarm is given out.

However, the existing fire alarm systems are usually passively monitored, and only after a fire occurs, an alarm can be given, although there is a certain disaster reduction prevention and control capability, a certain time is required for data information such as high temperature and smoke to be transmitted to the sensors, and the smoke sensor for detecting smoke is usually installed inside the fire alarm, and the process that smoke enters the fire alarm and is detected by the smoke sensor usually has a delay, which also causes the fire alarm to fail to give an alarm in time.

Meanwhile, the existing fire alarm device can only passively detect the ambient temperature through a sensor for detecting the temperature, but due to the reasons of low air density and low heat conductivity, when the orientation of the fire alarm device is not ideal enough, for example, a fire point deviates from the alarm device, the temperature sensor is difficult to sense the high temperature radiated by the fire point in time, and the fire alarm device can not alarm in time.
