Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed as broadly as the present invention is capable of other embodiments without departing from the spirit and scope thereof as defined by the appended claims.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. As used herein, the terms "vertical," "horizontal," "left," "right," and the like are for illustrative purposes only and do not denote a single embodiment.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The cable tunnel fire early warning device is composed of a pyroelectric ion fire early warning system, a temperature sensing optical fiber detector 1, an environmental quantity sensor 3, a computer and an intelligent terminal 6.

The heat release ion fire early warning system is provided with a heat release ion fire detector 2, and the heat release ions in the 2 sampling cable tunnels of the heat release ion fire detector are analyzed, so that whether an early fire disaster exists or not can inform operation and maintenance personnel to notice after the early fire disaster appears. When the temperature of the temperature-sensitive optical fiber detection cable rises sharply, the cable in the cable tunnel has risks, and at the moment, the potential fire hazard needs to be judged.

The environment quantity sensor 3 detects the environment quantity in the cable tunnel, and the control logic of the environment quantity sensor 3 is as follows:

1. when the pyroelectric ion detector gives an alarm, the temperature sensing optical fiber data is further analyzed, the cable temperature of the alarm area of the pyroelectric ion detector is scanned, and the abnormal condition of the cable temperature is seen. If the temperature of the cable jumps, the problem of the cable in a specific area is determined, the problem belongs to fire risks, and the problem is reported to a server and is emergently processed by maintenance personnel, such as measures of power failure or starting of a fire extinguishing device. If the temperature of the cable is not jumped or normal, the possibility of fire is low, and maintenance personnel regularly patrols and examines the cable.

2. When the temperature-sensitive optical fiber detector 1 gives an alarm, the pyroelectric particles do not give an alarm, and the parameters are normal, which may be caused by external temperature, and at this time, the pyroelectric particles belong to normal conditions, and are periodically inspected and processed by maintenance personnel.

3. Because the cable tunnel is in the place several meters deep underground, there are many kinds of gas of maintaining human body in the tunnel, such as CO2, etc., after personnel enter, may endanger personnel's life safety, so, the pyroelectric ion detector monitors the content of tunnel ambient gas in real time, the gaseous state of the real-time display cable tunnel, and report to the backstage system, when the maintainer needs to go to the cable tunnel construction, patrol and examine or confirm the warning, can conveniently look over the environmental state, maintainer's personal safety.

The cable tunnel fire early warning device is also provided with a detection device body, and the detection device body is movably arranged in the tunnel through a track; the pyroelectric ion fire early warning system, the temperature-sensing optical fiber detector 1, the environmental quantity sensor 3 and the background computer 4 are arranged in the detection device body.

The heat release ion fire early warning system further comprises:

the environment temperature sensor is used for detecting the environment temperature in the tunnel;

the dust sensor is used for detecting the dust accumulation condition in the tunnel;

and the temperature and humidity sensor is used for detecting temperature and humidity data of the environment in the tunnel.

The environmental quantity sensor 3 includes:

the circulating current transformer is used for detecting circulating current data of the tunnel cable, detecting current data of the cable in the tunnel and transmitting the current data to the heat release ion fire early warning system;

the cable temperature sensor is used for acquiring temperature data of the tunnel cable;

and the gas sensor is used for acquiring the change data of the gas content of the environment around the tunnel cable.

In the cable tunnel, when the pyroelectric ion fire equipment works normally, the pyroelectric ion fire equipment, the temperature-sensing optical fiber detector 1 and the environment quantity detection data are all connected into the pyroelectric ion detector, form unified data and judge the data, and then upload the data to a background computer 4 of a duty room for checking by duty personnel, and simultaneously upload the data to a cloud server 5 for data query of an intelligent terminal 6.
