The embodiment of the utility model described referring now to attached drawing, similar element numbers represent similar member in attached drawing
Part.
As shown in Figs. 1-3, elevator malfunction autoalarm 100 provided by the utility model, including master controller
110th, shutdown detection device 120, human body sensing device 130, alarm unit 140 and relay K.Wherein, master controller 110 is used for
Control elevator runs and detects whether elevator has failure, and master controller 110 has the first test side X1, the second test side
X2, an output terminal Y0 and a common end M0, while master controller 110 also has 0V voltage connections, the 24V for connecting power supply
Voltage connection.Shutdown detection device 120 is connected to the first test side X1, is used to detecting whether elevator door-closing in-place and to export
Door-closing in-place signal.Human body sensing device 130 is set in lift car 200 and is connected to the second test side X2, is used to detect
Whether someone and human-induced signal is exported in lift car 200.Alarm unit 140 is connected to output terminal Y0 and 24V direct currents
Between the cathode N in source, one end of relay K is connected to the output terminal Y0, and the other end is connected to the common end M0, public
End M0 is also attached to the anode L of 24V DC power supplies.When master controller 110 detects elevator faults, while receives the shutdown
In place after signal, the human-induced signal, control relay K is closed so that 140 place circuit of alarm unit is connected, and then
Alarm unit 140 is acted to export the alarm signal.
In the utility model, master controller 110 detect elevator whether with failure can by the design of software and hardware come
It realizes, and is the conventional design of this field, therefore repeat no more.
Preferably, alarm unit 140 is set on the place of long-term someone, such as room security, monitoring center, rental housing landlord are lived
Place etc., so that people can be allowed to see and hear alarm in time.Certainly, alarm unit 140 is not limited to be arranged on above-mentioned place,
It is equally possible that it is set on other public places.
With continued reference to shown in Fig. 1, the alarm unit 140 includes alarm alarm bell 141 in parallel and warning lamp 142, described
One end after alarm alarm bell 141, warning lamp 142 are in parallel is connected to output terminal Y0, and alarm alarm bell 141, warning lamp 142 are in parallel
The other end afterwards is connected to power cathode N.When master controller 110 controls the relay K to be closed, positive pole L, common end M0, after
The circuit conducting that electric appliance K, output terminal Y0, power cathode N are formed, therefore, the 141 jingle bell alarm of alarm alarm bell, while warning lamp
142 flickers send out alarm signal.
As shown in Fig. 2, in a kind of embodiment of the utility model, the shutdown detection device 120 is normally opened contact
Switch, which is set at the door head of elevator cage door 210, and one end of normally opened contact switch 120 is connected to institute
State the first test side X1, another termination voltage signal of the normally opened contact switch 120.After elevator cage door 210 is closed the door, two fan sedan-chairs
Door 210 is closed and is closed the normally opened contact switch 120, and therefore, the first test side X1 of master controller 110 will detect voltage
Signal, the voltage signal are the door-closing in-place signal, and master controller 110 is judged as that elevator shutdown is arrived according to the voltage signal
Position.
Certainly, shutdown detection device 120 is not limited to normally opened contact switch, can also detect elevator by other means
Shutdown state.In another preferred embodiment of the utility model, elevator is detected using Elevator Door Control device
Shutdown state.Specifically, which includes door machine controller, is connected and is controlled by it with door machine controller
Door machine motor, and door machine motor has an encoder, at the same door machine controller memory contain recorded during door machine self study it is default
Pulse signal.Door machine controller controls door machine motor action to drive 210 open and close door of elevator cage door, when elevator cage door 210 is closed the door
Afterwards, encoder can feed back a shutdown pulse signal to door machine controller, when door machine controller judges the shutdown pulse signal
When consistent with predetermined pulse signal, door machine controller is judged as elevator door-closing in-place, therefore exports door-closing in-place signal to master control
Device 110 processed.
Referring now to shown in Fig. 3, in the utility model, the human body sensing device 130 is infra-red sensor switch or light
Inductance inductive switch, human body sensing device 130 are set on the top in lift car 200, and the induction range of human body sensing device 130
The floor area of car 200 can be covered, to sense the personnel in car 200.
With reference to shown in Fig. 1-3, the operation principle of the utility model elevator malfunction autoalarm 100 is said
It is bright.
Under normal circumstances, master controller 110 controls elevator operation, and in running process of elevator, each elevator cage door 210 closes
Door in place when, shutdown detection device 120 will all export door-closing in-place signal, and by door-closing in-place signal transmission to master controller
110 the first test side X1, meanwhile, human body sensing device 130 is detected the personnel in lift car 200, when car 200
During interior someone, human body sensing device 130 can all export human-induced signal, and the human-induced signal is transmitted to master controller
110 the second test side X2.
In running process of elevator, if master controller 110 detects Lift out of order, meanwhile, elevator main controller 110
First test side X1 receives door-closing in-place signal, the second test side X2 receives human-induced signal, that is, while meet elevator
In shutdown state, lift car 200 when three someone, elevator faults conditions, 110 automatic decision of master controller is elevator event
Hinder oppressive, and control relay K is closed in time so that is born by positive pole L, common end M0, relay K, output terminal Y0, power supply
The circuit conducting that pole N is formed, therefore, alarm alarm bell 141 jingle bell alarm, warning lamp 142 flicker to send out alarm signal.
To sum up, due to the elevator malfunction autoalarm 100 of the utility model, equipped with for detecting whether elevator closes the door
Shutdown detection device 120 in place and for detect in lift car 200 whether the human body sensing device 130 of someone, work as master control
Device 110 processed detects elevator faults while receives the door-closing in-place signal of the output of shutdown detection device 120 and human body sensing dress
When putting the human-induced signal of 130 outputs, master controller 110 controls alarm unit 140 to act with output alarm signal, so as to make
Monitoring personnel or rescue personnel can learn that elevator faults are oppressive in time, are conducive to rescue in time, do not know how to call for help even
Personnel it is stranded when, the stranded long period can be also avoided, so as to improve the safety that elevator uses.
Above disclosed is only the preferred embodiment of the utility model, certainly cannot be new to limit this practicality with this
The interest field of type, therefore the equivalent variations made according to present utility model application the scope of the claims still belong to the utility model and are covered
Range.
