Detailed description of the invention
Below with reference to accompanying drawing, technical scheme of the present invention is described in detail.
Step on Nuisance alarms system based on autosense elevator is anti-, comprise n Intelligent alarming terminal, wherein, n is less than or equal to the number of floor levels k of elevator process, n Intelligent alarming terminal is separately positioned on each floor of elevator process, the power supply that described Intelligent alarming terminal comprises microcontroller and is attached thereto respectively, combined aural and visual alarm, communication port and m opto-electronic pickup, wherein, m >=1, each Intelligent alarming terminal also comprises m Reflector, each opto-electronic pickup of each Intelligent alarming terminal is separately positioned on the diverse location of corresponding floor elevator hoistway inwall, each Reflector of each Intelligent alarming terminal is arranged on the inner side of corresponding floor elevator door, when elevator door is opened completely, each Reflector faces each opto-electronic pickup respectively.Described opto-electronic pickup launches light beam all the time, and when Reflector faces opto-electronic pickup, the light beam that opto-electronic pickup sends is received by opto-electronic pickup via Reflector reflection, illustrates that now elevator door is opened.Described microcontroller realizes the data interaction with remote monitor and control end by communication port.The composition structure of described Intelligent alarming terminal as shown in Figure 1.
In the present embodiment, when the Intelligent alarming terminal of certain layer detects elevator faults, then control communication port immediately, by communication network, alarm message is uploaded to remote monitor and control end.The security of elevator or the communication device (such as: mobile phone) of service personnel also connect in a communication network; remote monitor and control end can after receiving alarm message; the communication device being rapidly to Security Personnel sends information, notifies that Security Personnel overhauls elevator at once, trouble-shooting.
In the present embodiment, each terminal also comprises the alarm display be connected with microcontroller, and described alarm display to be located at outside every floor elevator door other, for reporting to the police to the passenger waited outside elevator into elevator in time when Lift out of order.
In the present embodiment, the number n=k-1 of Intelligent alarming terminal, namely the bottommost floor of elevator process does not arrange Intelligent alarming terminal, because the bottom can not be stepped on empty dangerous.
Elevator common is at present divided into midsplit type layer door elevator and other open type layer door elevator according to the unfolding mode of elevator door.If elevator type is midsplit type layer door elevator, in order to detect the on off state of left and right two side doors of elevator, each Intelligent alarming terminal at least comprises 2 opto-electronic pickups and 2 pieces of Reflector, and 2 pieces of Reflector are arranged on left and right two side doors respectively, and its schematic diagram as shown in Figure 2 and Figure 3; If elevator type is other open type layer door elevator, because elevator door is only from folding, therefore each Intelligent alarming terminal at least comprises 1 opto-electronic pickup and 1 piece of Reflector, and its schematic diagram as shown in Figure 4, Figure 5.
The present invention also comprises based on above-mentioned anti-control method of stepping on sky warning, and the Intelligent alarming terminal of every floor all adopts this control method; First, system carries out initialization, make alarming value i=0, then, microcontroller every detection time T read an elevator door state, if each opto-electronic pickup does not all receive the folded light beam of Reflector, then when illustrating that elevator door cuts out or elevator door opens, lift car is positioned at this layer, and now alarming value i resets; If have at least 1 opto-electronic pickup to receive the folded light beam of Reflector, when then illustrating that elevator door is opened, lift car is not at this layer, this seasonal alarming value i=i+1, when alarming value i equals alarm threshold value I, microprocessor control combined aural and visual alarm is reported to the police, alarm display is reported to the police, alerting signal is uploaded to remote monitor and control end by communication port, resets alarming value i simultaneously.
In the present embodiment, detection time, T was 1 second, and alarm threshold value I is 3, why alarm threshold value is set as 3, was because general elevator door opens needs 3 seconds, closed again thus the wrong report caused after setting alarm threshold value can avoid layer door to open instantaneously.
The diagram of circuit of above-mentioned control method as shown in Figure 5.
Utilize and above-mentionedly step on Nuisance alarms system and control method based on autosense elevator is anti-, can detect that the non-flat bed of elevator stops the fault of opening the door.So-called " non-flat bed stops and opens the door " refers to, when certain layer of elevator door is opened, lift car some be positioned at this layer, and another part is positioned at the situation of another layer.Utilize the present invention can detect the three state of elevator: enabling that elevator is normal, the non-flat bed of elevator stops and elevator do not stop at this layer completely.In order to detect the fault that the non-flat bed parking of elevator is opened the door, in the present embodiment, each Intelligent alarming terminal comprises 2 opto-electronic pickups and 2 pieces of Reflector, and 2 opto-electronic pickups are separately positioned on the top and bottom of answering floor elevator hoistway inwall.When 2 opto-electronic pickups all do not receive the reflected light signal of Reflector when elevator door is opened, then illustrate that lift car is normally stopped at this layer, its schematic diagram as shown in Figure 7; When 2 opto-electronic pickups all receive the reflected signal of Reflector when elevator door is opened, then illustrate that lift car is not completely at this layer, triggering system is reported to the police, and its schematic diagram as shown in Figure 8; The reflected light signal of Reflector is received when the opto-electronic pickup being positioned at upper end is at door-opened elevator, the opto-electronic pickup being simultaneously positioned at lower end does not receive the reflected light signal of Reflector, then illustrate that non-flat bed parking enabling fault occurs elevator, and lift car is between this layer and lower one deck, triggering system is reported to the police, and its schematic diagram as shown in Figure 9; The reflected light signal of Reflector is received when the opto-electronic pickup being positioned at lower end is at door-opened elevator, the opto-electronic pickup being simultaneously positioned at upper end does not receive the reflected light signal of Reflector, then illustrate that non-flat bed parking enabling fault occurs elevator, and lift car is between this layer and last layer, triggering system is reported to the police, and its schematic diagram as shown in Figure 10.Intelligent alarming terminal is reported to the police to remote monitoring terminal according to fault type, is conducive to security or service personnel understands rapidly elevator faults type, improves the efficiency of failture evacuation.
Above embodiment is only and technological thought of the present invention is described, can not limit protection scope of the present invention with this, and every technological thought proposed according to the present invention, any change that technical scheme basis is done, all falls within scope.
