Detailed Description

The road tunnel evacuation inducing apparatus shown in fig. 1 includes inducing units disposed along the access roads at both sides of the tunnel, an environment sensing unit 4 installed at an evacuation exit 2 of the tunnel, and a central controller 3 connected to an input end of the inducing unit and an output end of the environment sensing unit 4, respectively; each of the tunnel evacuation exits 2 is provided with an induction unit including an upstream induction lamp group u disposed on an upstream side of the tunnel evacuation exit 2 ₁ ，u ₂ ，u ₃ ……u _n ]And a downstream induction lamp group ([ d ]) disposed at a downstream side of the tunnel evacuation exit 2 ₁ ，d ₂ ，d ₃ ……d _n ]) Each induction lamp group comprises a plurality of induction lamps 1 which are uniformly arranged at intervals, the induction lamps 1 are arranged facing the side wall of the tunnel and used for projecting induction images 11 which are directed to the side wall of the tunnel and close to the evacuation exit 2 of the tunnel, and the induction images 11 include, but are not limited to, human images moving towards the evacuation exit. The utility model discloses an utilize induced lamp 1 to the tunnel lateral wall throw the directional induced image 11 that closes on tunnel evacuation export 2, can be timely, effectual to sparse personnel induction, improve evacuation export 2's identifiability to improve evacuation efficiency by a wide margin. In addition, the evacuation induction device has simple structure and lower cost, and can be widely used according to actual conditionsThe method is applied to the highway tunnel.

In the present application, upstream means a vehicle entering direction in a traveling direction, and downstream means a vehicle leaving direction in the traveling direction. When a fire accident occurs in a tunnel, the general treatment measures are as follows: and the vehicles at the lower reaches of the accident point immediately exit the tunnel, the vehicles at the upper reaches of the accident point immediately stop, and the personnel in the vehicle immediately abandon the vehicle to escape in the upstream direction. In one embodiment of the present application, a green virtual human with an escape gesture is used as the induced image 11, and the escape gesture represents escape to the direction of the evacuation exit, then the escape gestures of the virtual human projected by the upstream light group and the downstream light group are just opposite, and the upstream light group will project a group of virtual human escaping to the downstream direction, and the downstream light group will project a group of virtual human escaping to the upstream direction,

an upstream switch is connected between the output end of the central controller 3 and the upstream induction lamp set, and a downstream switch is connected between the output end of the central controller 3 and the downstream induction lamp set. The central processing unit can adopt the existing drive circuit and the existing 51 single chip microcomputer. The induction lamp group adopts a control mode of a horse race lamp; when a fire disaster occurs in the tunnel, the central controller 3 controls a plurality of induction lamps 1 in the upstream lamp group or the downstream lamp group to be sequentially and circularly started from one side far away from the scattering port to one side near the scattering port according to a set frequency (such as 1Hz) through the upstream switch or the downstream switch, only one lamp in the lamp group is started at a time, after all the lamps are started once, the lamps are sequentially started again according to the sequence and the frequency, and the starting and extinguishing processes are repeated. By projecting the shadow gradually escaping to the evacuation exit at a certain frequency on the tunnel wall, a dynamic virtual human escape route is formed, so that the evacuation route selection of the staying people can be guided. Compared with evacuation indication signs, the induction lamp 1 is more intuitive, easier to identify and understand, and can guide detained people to make a quick decision on evacuation paths and improve evacuation efficiency under the emergency situation of fire accidents.

The distance between two adjacent induction lamps 1 can be set to be 10m-15m, and the arrangement amount of the induction lamps can be reduced while the induction effect is guaranteed, so that the cost can be saved. When there are a plurality of evacuation exits 2 in the tunnel, as shown in fig. 2, assuming that the distance between two adjacent evacuation exits 2 is L, the installation length of one set of lamp group is L/2, and the number of lamps in the upstream lamp group and the downstream lamp group is n ═ L/2 d. In general, the distance between two adjacent evacuation outlets 2 in the highway tunnel does not exceed 250m, and if d is 10m, the number n of the lamps in one lamp group is 12. FIG. 3 shows an example of a set of 12 inducing lamps 1, where 0 is on and 1 is off.

The induction lamp 1 can adopt an embedded projection lamp and is arranged on the maintenance way through an embedded structure; the installation mode of the induction lamp 1 does not occupy the space on the access road and does not influence the walking of people.

The environment sensing unit 4 comprises a carbon monoxide sensor, a visibility sensor, a temperature sensor and the like; and each tunnel evacuation exit 2 is provided with the above-mentioned environment sensing unit 4, and the environment sensing unit 4 can detect the environmental parameters such as CO (carbon monoxide), VI (visibility), Temp (temperature) in the tunnel. Each environment sensing unit 4 is in communication connection with the lamp group central controller 3 of the corresponding evacuation outlet 2, and the environment sensing unit blocks are also in communication connection with the tunnel remote control center.

When the environment sensing module detects that parameters such as CO, VI, Temp and the like near the evacuation exit 2 exceed standards (endanger personal safety), the environment information exceeding the standards is output to the tunnel remote control center and the central controller 3, the central controller 3 instructs a downstream switch to turn on a downstream induction lamp group according to the received information, an upstream switch turns off an upstream induction lamp group so as to induce detained people at the downstream of the evacuation exit 2 to continue to evacuate to the current evacuation exit 2, and detained people at the upstream of the evacuation exit 2 do not evacuate to the current evacuation exit 2 any more.

In this embodiment, when the environment sensing module detects that parameters such as CO, VI, Temp and the like near the evacuation exit 2 do not exceed the standard, the environment information that does not exceed the standard is output to the tunnel remote control center and the central controller 3, and the central controller 3 respectively turns on the upstream induction lamp group and the downstream induction lamp group by indicating the upstream switch and the downstream switch according to the received information, so as to induce the detained people on both sides of the evacuation exit 2 to rapidly escape to the current evacuation exit 2.
