Accompanying drawing explanation
Fig. 1 is function structure chart of the present utility model.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
See Fig. 1, the utility model provides a kind of illuminator based on RS485 bus, is mainly used in tunnel illumination, comprises optic module, RS485 gateway, at least one group of lighting apparatus and control centre.For system requirements, control centre is generally not on-the-spot in tunnel, for realizing controlling the lighting apparatus at scene, tunnel, utilizes RS485 bus protocol to realize carrying out bus marco to many group lighting apparatus.Optic module is fiber optic network, is located at scene, tunnel, convenient access RS485 gateway.
Control centre is connected with RS485 gateway by optic module, and lighting apparatus is connected with RS485 gateway; Described RS485 gateway for receiving the control signal from control centre, and sends a control signal to lighting apparatus.For control centre, by staff's control operation, the illumination opening and closing time etc. can be controlled.
Each group lighting apparatus includes processing terminal and fluorescent tube, and fluorescent tube is connected with RS485 gateway by processing terminal; Processing terminal is used for reception control signal, and controls lamp works according to this control signal.Fluorescent tube is preferably LED.
Tunnel illumination is generally divided into base lighting and adds strong illumination.Base lighting runs through whole tunnel, in the present embodiment, the mode that above-mentioned control centre controls lighting apparatus is defined as base lighting, the primary demand of tunnel illumination can be met, but further from aspects such as the energy savings of the fail safe of vehicle, tunnel illumination, the utility model also needs to add strong illumination.Add strong illumination and be generally positioned at entrance and outlet section.
For realizing adding strong illumination, the illuminator of the present embodiment also comprises sensor assembly, and sensor assembly realizes the automatic detection of environment to external world, realizes Automated condtrol LED.Sensor assembly can comprise in luminance sensor, automobile sensor and CO/VI detector any one or multiple.Wherein, luminance sensor is connected with RS485 gateway by optic module; Luminance sensor, for detecting ambient light line strength signal; RS485 gateway is used for by the light intensity signal of optic module reception from luminance sensor, and this light intensity signal is sent to processing terminal, to make processing terminal according to the brightness of this light intensity Signal Regulation fluorescent tube.So-called luminance sensor, be light sensor, the change of external environment light intensity can be detected, its Cleaning Principle is common practise, luminance sensor is installed and tunnel outer by the present embodiment, for detecting the light intensity outside Tunnel, lighting apparatus regulates the brightness adding strong illumination according to the light intensity of tunnel outer.
Automobile sensor can the work information of automobilism, as vehicle fleet size, Vehicle Speed convert electric signal to and be sent to lighting apparatus.For tunnel illumination, the different volume of traffic is different to lighting demand, and the volume of traffic is larger, the faster demand to illumination of average speed also strengthens thereupon.This automobile sensor is connected with RS485 gateway by optic module; RS485 gateway, for being received the first detection signal from automobile sensor by optic module, and is sent to processing terminal by this first detection signal, regulates the brightness of fluorescent tube to make processing terminal according to this first detection signal.This first detection signal is then contain the information such as vehicle fleet size information and the speed of a motor vehicle, makes lighting apparatus can regulate the brightness of fluorescent tube according to these external adjustment intellectualities, for vehicle provides safer environment in the traveling in tunnel.
Tunnel is a kind of special tubular structure thing, because space is little, there is the feature of seal, the waste gas that the vehicle of passing through tunnel discharges, as rationally emitted the gathering that can cause carbon monoxide and suspended particulate substance not in time, by the personal safety of the vehicle driver and conductor and maintenance staff that are directly connected to tunnel of passing through.CO/VI detector is carbon monoxide and the visibility checkout gear of tunnel tailored version, is generally arranged on tunnel side wall, provides concentration and the visibility detected value of the carbon monoxide in tunnel, to take corresponding measure in time.The CO/VI detector of the present embodiment is connected with RS485 gateway by optic module; Described RS485 gateway, for being received the second detection signal from CO/VI detector by optic module, and is sent to processing terminal by this second detection signal, regulates the brightness of fluorescent tube to make processing terminal according to this second detection signal.This second detection signal then includes carbonomonoxide concentration signal and visibility signal.
In the present embodiment, for base lighting with add strong illumination and be respectively arranged with preferably basic, the priority level of base lighting, higher than the preferred rank adding strong illumination, directly can control illumination by control terminal, can regulate brightness of illumination simultaneously.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection range of the utility model claim.
