Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention rather than limiting the invention.It also should be noted that in order to just
Only the parts related to the present invention are shown in description, attached drawing rather than entire infrastructure.
Embodiment one
Fig. 1 is the flow chart of the detection method for the accidental movement of elevator cage that the embodiment of the present invention one provides, the present embodiment
It is applicable to whether there is a situation where accidental movements to detect to lift car, this method can be by accidental movement of elevator cage
Detection device execute, which can be integrated in the equipment such as computer.
Gradually increased for accident rate caused by accidental movement of elevator cage, country in time issued elevator manufacture with
It is single that No. 1 modification of safety standard standard GB7588-2003 is installed.Leveling in the case of the standard requirements door-opened elevator, again leveling
Control need to check the accidental movement of carriage, and lock elevator, forbid running.No. 1 modification single needle of GB7588-2003 anticipates to carriage
The braking distance of outer movement has to get off clearly stipulate that accidental movement occurs from carriage and leaves level position to stop, total shifting
Dynamic distance is no more than 1.2 meters.For the standard requirements, many elevator control systems pass through hardware realization carriage currently on the market
Accidental movement defencive function, few detections by software realization accidental movement of elevator cage.For above situation, the present invention
Embodiment provides a kind of detection method of accidental movement of elevator cage, and Fig. 1 is a kind of elevator car that the embodiment of the present invention one provides
The detection method flow chart of compartment accidental movement, as shown in Figure 1, this method comprises:
S110, the condition feedback signal for monitoring elevator, and determined locating for the elevator according to the condition feedback signal
Working condition.
In the embodiment of the present invention, condition feedback signal can be the signal for being able to reflect elevator operating condition information, can be with
It is using sensor detection signal, comprehensive multiple and different signal determines working condition locating for elevator.Work locating for elevator
State can be divided into many types, such as can be high-speed cruising state, door area standby mode, suspected malfunctions state and enter door
Area starts to stop scalariform state etc..Optionally, the condition feedback signal includes: hall door lock signal, gate lock signal and door area signal.
In general, we claim the door that can be seen outside elevator to be known as hall door, are also layer door.And in electricity after elevator is shut in elevator
The door seen in ladder is known as gate.Elevator door zone is exactly the enabling region in elevator shaft, it is normal for, elevator in this area
Door can be just opened, does not otherwise allow to open door.Hall door lock signal can reflect the state of hall door, and car door lock can reflect gate
State, can determine whether elevator is located at normal door region by door area signal.It is understood that hall door lock signal,
Gate lock signal and door area signal all have two kinds of optional states.Optionally, first state can be OFF, and the second state can be with
For ON.It can be, when the hall door lock signal, the gate lock signal and door area signal are in first state, really
The fixed elevator is in suspected malfunctions state；It is described when the hall door lock signal, the gate lock signal are in first state
When door area's signal is in the second state, determine that the elevator is in door area standby mode.It specifically can be the hall door of acquisition elevator
Lock signal 40GS, gate lock signal 40DS, door area signal DZ, detect hall door lock signal 40GS and gate lock signal 40DS is
OFF, and door area signal DZ be ON when, determine that elevator is in door area standby mode.Detect hall door lock signal 40GS, car door lock letter
When number 40DS and door area signal DZ is OFF, determine that elevator is in suspected malfunctions state.
Optionally, it is described working condition locating for the elevator is determined according to the condition feedback signal after, also wrap
It includes: when the elevator is in door area standby mode, counting the duration of door area standby mode, wherein the door area
Standby mode is to confirm that hoistway door and gate are in open state according to the condition feedback signal, and carriage is in door
Area；If the duration of door area standby mode exceeds the second given threshold, judge whether the elevator is in described doubtful
Malfunction.Wherein, the second given threshold is used to limit response time and the time for signal filtering.It is super when the duration
Out when the second given threshold, hall door lock signal 40GS, the gate lock signal 40DS and door area signal DZ of elevator are detected again, if
When detecting that hall door lock signal 40GS, gate lock signal 40DS and door area signal DZ are OFF, determine that elevator is in suspected malfunctions shape
State.Optionally, the duration of the statistics door area standby mode, specifically: starting first timer, when described first
When timer meter is full, determine the duration of door area standby mode beyond the second given threshold.Illustratively, the first timing
Device can be T1, and timer duration can be 200ms.
S120, when the elevator is in suspected malfunctions state, count the duration of the suspected malfunctions state,
In, the suspected malfunctions state be confirm that hoistway door and gate are in open state according to the condition feedback signal, and
Carriage is not in an area.
If the duration of S130, the suspected malfunctions state exceeds the first given threshold, determine that lift car is anticipated
Outer movement.
In the embodiment of the present invention, when detecting that hall door lock signal 40GS, gate lock signal 40DS and door area signal DZ are OFF
When, determine that elevator is in suspected malfunctions state.When the duration of suspected malfunctions state being more than certain length, it may be considered that
There is failure in elevator, that is, hoistway door and gate are in open state, and within the scope of the area elevator Bu Men
Duration is too long, it is determined that accidental movement occurs for lift car.It is judged as that carriage accidental movement detects failure, forbids elevator
Operation.It can star corresponding alarm operation simultaneously, avoid the generation of accident.Maintenance measure can also be started as early as possible, avoid by
It is inconvenient in elevator faults bring.Optionally, the duration of the statistics suspected malfunctions state, specifically: starting the
Two timers determine the duration of the suspected malfunctions state beyond the first setting threshold when the second timer meter is full
Value.Wherein, the time span that the first given threshold is set under being the time required to elevator stopping, such as can be
300ms.Different accidental movement protective device braking abilities is different, and the brake response time is different, as long as passing through movement
Distance calculation formula calculates detection time and the response time of accidental movement, guarantees that total moving distance is no more than 1.2 meters and just accords with
It closes and requires.So it is more flexible to the detection time of carriage accidental movement, due to the performance difference of accidental movement protective device
It is fixed.The time span of namely above-mentioned first timer and second timer can be adjusted according to the actual situation setting, if
Determining result only needs to guarantee that total moving distance is no more than 1.2 meters.
The technical solution of the embodiment of the present invention determines work locating for elevator by monitoring the condition feedback signal of elevator
State determines that accidental movement occurs for lift car when the duration that elevator is in suspected malfunctions state being more than given threshold.
The response time for reducing accident improves the safety of elevator, avoids the occurrence of casualty accident.
