Sensor assembly（2）There is the body of a matrix, and right in the two opposite side walls on the inside of the body concave port
A pair of infrared transmitters and a pair of infrared remote receivers should be embedded with.As shown in Figure 2, a pair of infrared transmitters and connect for infrared a pair
Receive device and be respectively infrared transmitter（51）, infrared transmitter（52）And infrared remote receiver（53）, infrared remote receiver（54）.Infrared connect
Receive device（53）Receive infrared transmitter（51）The infrared light that is launched, infrared remote receiver（54）Receive infrared transmitter（52）Sent out
The infrared light that penetrates.Infrared transmitter（51）With infrared remote receiver（53）One group of infrared emission receiving module is constituted, matrix is arranged in
The top of body；Infrared transmitter（52）With infrared remote receiver（54）Composition another set infrared emission receiving module, is arranged in
The bottom of matrix body.
Sensor assembly（2）With processor module（3）Connection, sensor assembly（2）The biography that sensor on body is obtained
Sense information, that is, the transmission of conducting situation and the processor module of two groups of infrared emission receiving modules（3）.Processor module（3）
Logical analyses and calculation process are carried out after receiving this heat transfer agent, so as to obtain the status information of elevator operation.
Sensor assembly（2）It is installed on outside lift car, when elevator runs to a certain floor stopping, elevator hoistways inwall
On flat bed block be exactly in sensor assembly（2）Concave port inside, infrared transmitter（51）And infrared transmitter（52）Send out
The infrared light that penetrates is blocked by flat bed block, infrared remote receiver（53）And infrared remote receiver（54）Infrared signal cannot be received.
Processor module（3）Be blocked using two groups of infrared emission receiving modules, with the logic state being not turned in the time, sentence
Power-off ladder is arrived at, rests on certain flat bed, floor.
Elevator from halted state be changed into uplink state when, lift car is moved upwards, and flat bed block will be relative to elevator car
Railway carriage or compartment position moves down.Infrared transmitter（51）Because being located at sensor assembly（2）Top, its launch infrared light will depart from first flat
Blocking for block of layer and first by infrared remote receiver（53）Receive.Infrared transmitter（52）It is located at sensor assembly（2）Bottom, its
The infrared light that penetrates is in blocking for flat bed block of disengaging afterwards by infrared remote receiver（54）Receive.Processor module（3）Using above
One group of infrared emission receiving module is first turned on, the sequential logic turned on after set below infrared emission receiving module, judges elevator
For uplink state.
Elevator from halted state be changed into downstream state when, lift car is moved downward, and flat bed block will be relative to elevator car
Move on the position of railway carriage or compartment.Infrared transmitter（52）Because being located at sensor assembly（2）Bottom, its launch infrared light will depart from first flat
Blocking for block of layer and first by infrared remote receiver（54）Receive.Infrared transmitter（51）It is located at sensor assembly（2）Top, its
The infrared light that penetrates is in blocking for flat bed block of disengaging afterwards by infrared remote receiver（53）Receive.Processor module（3）Using following
One group of infrared emission receiving module is first turned on, above the sequential logic that turns on after one group of infrared emission receiving module, judge elevator
For downstream state.
During elevator is travelled to next floor from a certain floor, in certain time length, two groups of infrared emissions connect
Receiving module, conducting state is simultaneously in because clear is blocked.Processor module（3）Using two groups of infrared emission receiving modules
The logical relation simultaneously turned in unit interval length, judges that elevator is enforcement state.
When passing through from arbitrary floor during elevator travels, two groups of infrared emission receiver modules can be hidden because of the flat bed block short time
Keep off and successively disconnect, afterwards again because quickly through flat bed block, departing from and blocking and priority is again at conducting state.Processor module
（3）Successively disconnect the logical relation of successively conducting again using two groups of infrared emission receiving modules at short notice, judge that elevator is passed through
A floor is crossed.
A kind of elevator operation information Internet video stacking apparatus with phonetic function, when the device is installed, by management
The total number of floor levels of software set elevator work and it is currently located floor.During ascending for elevator, per pass flat bed block, current
Jia 1 on number of floor levels, finally give current floor when elevator stops；When elevator is descending, per pass flat bed block, in current building
Subtract 1 in the number of plies, finally give current floor when elevator stops.Processor module（3）Addition is done using up, descending subtraction is done
Logical relation, the operation information of continuous updating elevator.
After ascending for elevator or downward movement, sensor assembly（2）On two groups of infrared emission receiving modules successively switched on,
When should travel in normal working hourss to next floor and be blocked, but do not blocked again all the time, but long-time is in
Conducting state, that is, after elevator have left a floor, cannot normally arrive at next floor all the time.Processor module（3）Profit
With two groups of infrared emission receiving modules in unit interval length both without flat bed block, and the logical relation not being blocked, judge
Elevator occurs in that unusual conditions such as " card layers ".When there is unusual condition, device can the prompting of image enterprising line character flicker,
The modes such as voice broadcast warning information are warned to related personnel.
Processor module（3）Also with voice module（4）Connection, processor module（3）The elevator operation letter that parsing is obtained
Breath synchronized transmission is to voice module（4）Real-time broadcasting is carried out, content is reported and volume can be changed and adjust.
Processor module（3）By mixed-media network modules mixed-media（5）With outside network digital camera（11）And digital hard disk recording
