Description of drawings
Fig. 1 is the wherein constructional drawing of an embodiment of the utility model light curtain control system;
Fig. 2 is the constructional drawing figure of another embodiment of the utility model light curtain control system.
The specific embodiment
As shown in Figure 1, a kind of light curtain control system comprises light curtain 110, door controller 120, master controller 130 and read out instrument 140; Described door controller 120 connects described light curtain 110 and described read out instrument 140, described master controller is open the door or the close the door master controller 130 of instruction of the delivering according to the described door controller 120 that receives, and described read out instrument 140 is for showing the read out instrument 140 of the luminous point mode of operation in described light curtain 110.The basic structural unit of light curtain is emission, the luminous point that receives infrared beam at present, therefore can be by to the reading judgement and control and realize setting logic of each luminous point state, block for a long time other customizable functionality such as logic such as simple shelter height judgement, single described luminous point.Described door controller 120 can receive the data message that light curtain 110 passes over, and described data message comprises: current total state of light curtain 110, the state of each luminous point.Current total state of described light curtain 110 refers to specifically whether the light curtain is blocked and the light curtain two states that whether works.The state of described each luminous point comprises: the luminous point in described light curtain 110 is blocked, the luminous point in described light curtain 110 is not blocked and described light curtain 110 in luminous point damage three kinds of states.
Above-mentioned light curtain control system, directly show by the status information of read out instrument with each luminous point in the light curtain, the user can know the mode of operation of particular location luminous point in the light curtain by read out instrument, thereby understand the mode of operation of light curtain, facilitate the user to be confirmed whether to notify the maintainer to keep in repair.
Therein in embodiment, described light curtain control system, described read out instrument comprises corresponding to the luminous point in described light curtain and the LED lamp that is equal to luminous point quantity in described light curtain.The read out instrument of the LED lamp that the luminous point quantity in employing and described light curtain is equal to, the mode of operation of luminous point in the display light curtain effectively, represent the unobstructed work of luminous point with LED lamp blueness, extinguish with the LED lamp and represent that luminous point is blocked, represent that with LED lamp redness luminous point damages or conductively-closed.The user is by the mode of operation of luminous point in LED lamp different colours and light on and off identification light curtain.
As shown in Figure 2, in embodiment, described light curtain control system also comprises warning device 150 therein; Described warning device 150 starts the warning device 150 of reporting to the police for when the discontinuous single described luminous point of setting quantity is blocked.The user is in use that the discontinuous single described luminous point that quantity can not occur setting is blocked under normal circumstances, object blocks luminous point through the induction region of light curtain, during normal the use, the single described luminous point of the single described luminous point in induction region upper end and lower end can not occur is blocked, and the middle situation that does not have luminous point to be blocked, when a plurality of discontinuous single described luminous points of appearance are blocked, the alert notice master controller, elevator door still normally cuts out.Setting quantity in the present embodiment can freely limit, and is 3 o'clock if select to set quantity, and the interval luminous point number of described warning device between the single described luminous point that is blocked is 3 o'clock, starts warning device.
In embodiment, described light curtain control system also comprises and detects the detecting device whether luminous point in described light curtain damages therein.Whether described detecting device damages for detection of the luminous point in the light curtain, and the result that detection obtains is transferred to door controller, by door controller, the damage luminous point that detects is shielded.
Therein in embodiment, described light curtain control system, described door controller in described light curtain arbitrarily luminous point shield, and the discontinuous single described luminous point of setting quantity is blocked the door controller of timing.This function of door controller makes described light curtain controller to mask some N/R luminous points according to residing working environment, does not open the part luminous point in described light curtain.In the present embodiment, door controller detects the luminous point in the light curtain that obtains damaging according to detecting device, and with its shielding, guarantees that described light curtain when minority light curtain luminous point damages, still can work.Door controller can be set certain hour and be blocked judgement time of timing as the discontinuous single described luminous point of setting quantity, if the lasting discontinuous single described luminous point that setting quantity occurs of light curtain is blocked in setting-up time, be considered as accidental occlusion state, if the state that the lasting discontinuous single described luminous point that setting quantity occurs of light curtain is blocked exceeds setting-up time, be considered as the malice occlusion state, door controller sends to master controller with malice occlusion state information, is determined the action of specifically taking by master controller.Described accidental occlusion state refers to involuntary blocking; Described malice is blocked and is referred to that subject intent blocks.
Therein in embodiment, described light curtain control system, the arrangement mode of LED lamp described in described read out instrument is identical with the arrangement mode of luminous point in described light curtain.Arrangement mode with the LED lamp in the present embodiment is designed to identical with the arrangement mode of luminous point in described light curtain, the user can obtain according to the mode of operation of the LED lamp on read out instrument luminous point mode of operation corresponding in the light curtain, obtain the current circumstance of occlusion in elevator every district, the mode of operation of judgement elevator door is convenient to distinguish faster that failure condition keeps in repair with notice repair and maintenance personnel.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
