Specific embodiment
Below with reference to accompanying drawing, technical scheme is described in detail.
Prevent stepping on Nuisance alarms system based on autosense elevator, including n Intelligent alarming terminal, wherein, n is less than or equal to electricity
The number of floor levels k that ladder passes through；N Intelligent alarming terminal is separately positioned on each floor of elevator process, described Intelligent alarming terminal
Power supply, audible-visual annunciator, COM1 and the m photoelectric sensor being attached thereto including microcontroller and respectively, wherein,
M >=1, each Intelligent alarming terminal also includes m reflecting piece, and each photoelectric sensor of each Intelligent alarming terminal is separately positioned on
The diverse location of corresponding floor elevator hoistway inwall, each reflecting piece of each Intelligent alarming terminal is arranged on corresponding floor elevator door
Inner side, when elevator door fully opens, each reflecting piece faces each photoelectric sensor respectively.Described photoelectric sensor is launched all the time
Go out light beam, when reflecting piece faces photoelectric sensor, the light beam that photoelectric sensor sends is via reflecting piece reflection by photoelectricity
Sensor receives, and illustrates that now elevator door is opened.Described microcontroller realizes the number with remote monitoring end by COM1
According to interaction.The composition structure of described Intelligent alarming terminal is as shown in Figure 1.
In the present embodiment, the Intelligent alarming terminal when certain layer detects elevator faults, then control COM1 to lead to immediately
Cross communication network and warning message is uploaded to remote monitoring end.The communication device of the security of elevator or maintainer is (for example: handss
Machine) also connect in a communication network, remote monitoring end can be after receiving warning message, rapidly to the communication dress of Security Personnel
Put the information of sending, notify Security Personnel to overhaul elevator at once, fix a breakdown.
In the present embodiment, each intelligent terminal also includes the alarm display being connected with microcontroller, and described alarm shows
Show that device is located at outside every floor elevator door other, in Lift out of order in time to the passenger waiting outside elevator into elevator
Report to the police.
In the present embodiment, number n=k-1 of Intelligent alarming terminal, the bottommost floor that is, elevator passes through is not provided with intelligence
Alarm terminal, because the bottom will not step on empty danger.
Elevator common at present is 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 include 2 photoelectric sensors and 2 pieces of reflecting piece, 2 pieces of reflecting piece are separately mounted on left and right two side doors, and its schematic diagram is such as
Shown in Fig. 2, Fig. 3；If elevator type is other open type layer door elevator, because elevator door is only from folding, therefore each is intelligently reported
Alert terminal at least includes 1 photoelectric sensor and 1 piece of reflecting piece, and its schematic diagram is as shown in Figure 4, Figure 5.
Present invention additionally comprises based on the above-mentioned anti-control method stepping on sky warning system, the Intelligent alarming terminal of every floor is all adopted
Use this control method；First, system is initialized, and makes alarming value i=0, and then, microcontroller reads every detection time t
Elevator door state, if each photoelectric sensor does not all receive the reflected beams of reflecting piece, illustrates that elevator door cuts out or electricity
When terraced door is opened, lift car is located at this layer, and now alarming value i resets；If at least 1 photoelectric sensor receives reflecting piece
The reflected beams, then explanation elevator door when opening lift car not in this layer, this seasonal alarming value i=i+1, as alarming value i etc.
When alarm threshold value i, microprocessor controls audible-visual annunciator is reported to the police, alarm display is reported to the police, and alarm signal is passed through communication ends
Mouth is uploaded to remote monitoring end, resets alarming value i simultaneously.
In the present embodiment, detection time t be 1 second, alarm threshold value i be 3, why alarm threshold value is set as 3, be because
Open needs 3 seconds for general elevator door, set alarm threshold value and layer door moment can be avoided again to close thus leading to after opening
Wrong report.
The flow chart of above-mentioned control method is as shown in Figure 6.
Prevent stepping on Nuisance alarms system and control method based on autosense elevator using above-mentioned, the non-of elevator can be detected
The fault that flat bed parking is opened the door.So-called " non-flat bed stops and opens the door " refers to, when certain layer of elevator door is opened, lift car has one
Divide and be located at this layer, and another part is located at another layer of situation.The three state of elevator: elevator can be detected using the present invention
Normally, the parking of elevator non-flat bed is opened the door and elevator does not stop in this layer completely.In order to detect the parking of elevator non-flat bed
The fault opened the door, in the present embodiment, each Intelligent alarming terminal includes 2 photoelectric sensors and 2 pieces of reflecting piece, and 2 light
Electric transducer is separately positioned on the top and bottom answering floor elevator hoistway inwall.When 2 photoelectric sensors are opened in elevator door
Shi Junwei receives the reflected light signal of reflecting piece, then explanation lift car is normally stopped at this layer, and its schematic diagram is as shown in Figure 7；
When 2 photoelectric sensors all receive the reflected signal of reflecting piece when elevator door is opened, then explanation lift car does not exist completely
This layer, triggers system alarm, and its schematic diagram is as shown in Figure 8；Receive when the photoelectric sensor positioned at upper end is in door-opened elevator
The reflected light signal of reflecting piece, the photoelectric sensor being simultaneously located at lower end does not receive the reflected light signal of reflecting piece, then illustrate
There is non-flat bed parking enabling fault in elevator, and lift car is located between this layer and next layer, triggers system alarm, its signal
Figure is as shown in Figure 9；Receive the reflected light signal of reflecting piece when the photoelectric sensor positioned at lower end is in door-opened elevator, simultaneously position
Photoelectric sensor in upper end does not receive the reflected light signal of reflecting piece, then explanation elevator occur non-flat bed stop open the door therefore
Barrier, and lift car, positioned between this layer and last layer, triggers system alarm, its schematic diagram is as shown in Figure 10.Intelligent alarm is eventually
Reporting to the police to remote monitoring terminal according to fault type in end, is conducive to security or maintainer to understand rapidly elevator faults type, carries
The efficiency of high failture evacuation.
Above example technological thought only to illustrate the invention is it is impossible to limit protection scope of the present invention with this, every
According to technological thought proposed by the present invention, any change done on the basis of technical scheme, each fall within the scope of the present invention
Within.
