The array of pressure sensors of level and skirt panel clearance pressure, detects elevator speed and the magnetic sensor in direction, according to pressure
Force sensor array exports first judged and judges controller, defeated according to photosensor arrays output and magnetic sensor
Second gone out judges controller, for the warning device array to give a warning to passenger, the emergency stop device for elevator emergency stop.
Further, the photosensor arrays share multiple units, are intervally arranged along staircase direction, each unit
On the skirt panel of staircase both sides, there are two groups of photoelectric sensors in a unit, sensor array output is transmitted to second
Judge controller.
Further, the array of pressure sensors shares multiple units, and each unit installed in for uplink by helping
Ladder forms on the lower step edge of upper step and skirt panel with multiple pressure sensors of step relative position, the biography
The output of sensor array is transmitted to the first judgement controller.
Further, the magnetic sensor by the different magnetic intensities installed in the step back side a plurality of magnetic stripe and be installed on
The magnetodiode circuit of staircase inlet is formed, and sensor output is transmitted to the second judgement controller.
Further, described first judges that controller is installed on staircase entrance, is filled respectively with array of pressure sensors, warning
Put array to be connected, for judging the output of array of pressure sensors, if the output abnormality at a certain position will activate the position
Warning device.
Further, described second judge controller also with photosensor arrays, magnetic sensor, emergency stop device phase
Even, for judging photosensor arrays output and magnetic sensor output, appearance is abnormal will to activate emergency stop device.
Further, the warning device array is respectively installed on skirt panel corresponding with each pressure sensor unit.
Further, the elevator emergency stop device is installed on staircase inlet.
Beneficial effects of the present invention are as follows：The supporting safety device of escalator of the present invention, employs a variety of sensings
Device detects a variety of possible security risks, and it is thorough to consider, False Rate is relatively low, and has warning device and emergency stop device, energy
Effectively prevent the generation of all kinds of escalator security incidents, ensure the life security of the people.

Embodiment
The present invention is described further below in conjunction with the accompanying drawings.
As shown in Figure 1, the photosensor arrays 1 share multiple units, it is intervally arranged along staircase direction, each unit
All on the skirt panel of staircase both sides, there are two groups of photoelectric sensors in each unit.Sensor array output is transmitted to the
Two judge controller.Whether the laser that the output of photoelectric sensor is produced by side is received by opposite side determines (i.e. in light path
Blocked with the presence or absence of object).Under normal circumstances, two sensors or detect there is thing in light path up and down in same unit
Body exists (i.e. currently with the presence of passenger in the unit position) or can't detect in light path and has object (i.e. currently without multiplying
Visitor is in the unit position).When upper sensor will can't detect light in the situation for having passenger and falling down accidentally, some unit
With the presence of object on road, and lower sensor is still detected in light path with the presence of object.The output of photoelectric sensor at this time will with just
Reason condition is different.
As shown in Fig. 2, the array of pressure sensors 2 shares multiple units, each unit is by installed in for uplink
Staircase forms on the lower step edge of upper step and skirt panel with multiple pressure sensors of step relative position.Should
Sensor array output is transmitted to the first judgement controller.When the foot of passenger steps down in or is pressed in pressure sensor position,
Different output will be produced.
As shown in figure 3, the magnetic sensor is by the different magnetic stripe 4 of the magnetic intensity installed in the step back side and installed in helping
The magnetodiode circuit 5 of terraced entrance is formed.Incremental a plurality of of magnetic intensity of identical quantity is fitted with per the level-one step back side
Magnetic stripe 4.Therefore whether uplink or descending elevator, under normal circumstances, the magnetic field residing for magnetodiode circuit 5 are periodically
Change and in one cycle strength increase change or change of successively decreasing, magnetodiode circuit 5 can be according to the change in magnetic field
Change outputs signals to the second judgement controller.When the unexpected speed of service of elevator changes or direction changes, magnetic field
The frequency of change by change or a cycle in change of magnetic field strength rule will with it is opposite under normal circumstances.Therefore magnetic
Quick 5 signal output of diode circuit will change.
Described first judges that controller is installed on staircase entrance, passes through with array of pressure sensors 2, warning device array 3
Circuit is connected.The output of array of pressure sensors is detected, if the pressure sensor unit output at a certain position reaches setting
Pressure threshold, will activate the warning device of the position.The setting of pressure threshold is considered as reducing erroneous judgement to the greatest extent, can carry out certain
Experiment determines pressure threshold.
Described second judges that controller is installed on staircase entrance, with photosensor arrays, magnetic sensor, emergency stop device
It is connected by circuit, can determines whether that passenger falls down according to the output of above-mentioned photosensor arrays, according to above-mentioned magnetic biography
The output of sensor judges whether elevator speed or direction change suddenly, once emergency stop will be activated by case above occur
Device.
As shown in Figure 2 and Figure 4, the warning device array 3 is installed on apron corresponding with each pressure sensor unit
On plate.When the warning device of a certain position receives the activation signal of the first judgement controller, voice reminder passenger will be reported and paid attention to
Underfooting safety.The emergency stop device receives the activation signal of the second judgement controller, will stop the operation of escalator, avoids out
Existing security incident, as shown in Figure 5.
First judges that controller can use the product of WS1521 models, but not limited to this；Second judges that controller can be with
Using the product of WS1521 models, but not limited to this；Warning device is MAX9812 voice module circuits.The emergency stop device is
The exigency stop system that elevator interior carries.
