The kind when inner side of bottom plate 1 is provided with, the clock is connected with embeded processor, and temporal information passes through embedded Processor is delivered to LCDs and shown.
The intelligent external calling device of the elevator is provided with multi-media display 2, and the multi-media display 2 includes liquid crystal Display screen, embeded processor, acoustic component, the embeded processor, acoustic component are arranged at the inner side of bottom plate 1, liquid crystal display Screen is arranged on bottom plate 1, and LCDs, the acoustic component are connected with the embeded processor described in the bottom plate 1.Institute State multi-media display 2 and play the content of multimedia such as propaganda film, advertisement, prompting and prompting elevator real time information.The bottom plate 1 Wireless communication module is built-in with, wireless signal can be transmitted and wireless signal, such as WIFI, bluetooth, the external calling device is received LCDs can be delivered to by wireless communication module date received, time, Weather information, and by embedded processor Display.
The button swiping card part 3, including card reader 5 and code keypad 6, card reader 5 are used to read owner's IC-card, send Call information forwards outgoing call request to embeded processor, by it, and certification is reached by rear direct calling elevator, and is sent to automatically Need arrival floor.Button is used to input password, sets the operation such as password, and visitor can call electricity by using code keypad 6 Ladder.User right has been set in the IC-card of owner, or the password of user and the elevator authority of the user are bindings, are made Used time user by swiped the card in card reader 5 or directly on code keypad 6 button, embeded processor certification passes through backward Elevator multiple control device sends instruction, and elevator multiple control device distribution elevator reaches user's calling layer, and user is sent into designated floor, Encrypted message is the same with card using information, is forwarded by liquid crystal display 2, while liquid crystal display 2 can provide operation indicating.Button brush Clamping part 3 is used for the security and convenience for ensureing owner-occupation environment.
The outgoing call key component 4 include up button and descending button, the up button, descending button with it is embedded Processor is electrically connected with.The outgoing call key component 4 is invalid when the function of button swiping card part 3 is normal, in button swiping card part 3 Ascending for elevator, descending is controlled when abnormal.The function of recovering traditional outgoing call button is played when button swiping card part 3 is abnormal. The circuit of embeded processor and outgoing call key component 4 is obstructed when the function of button swiping card part 3 is normal, when button is swiped the card portion When part 3 is abnormal, what the circuit of embeded processor and outgoing call key component 4 was to turn on.
The embeded processor gathers elevator information in real time from multiple lift control system, display ascending for elevator, it is descending, arrive Reach, the information such as floor.Simultaneously from clock, the device acquisition time such as temperature sensor, air particle collector, temperature, humidity, The presentation of information such as weather/air quality.Support to play the content of multimedia such as publicity pictures, advertisement, video.
Embeded processor, receives the call information of button swiping card part 3 when the function of button swiping card part 3 is normal and handles After be forwarded to elevator multiple control device so that control ascending for elevator, it is descending and stop at the same do not receive outgoing call key component 4 transmission Information.When the dysfunction of button swiping card part 4 can not transmit call information, receive the call information of outgoing call key component 4, And be forwarded to after handling elevator multiple control device so as to controlling ascending for elevator, it is descending and stop.
The LCDs receives the command signal of user's input, and command signal sends embedded processor to, embeds Formula processor sends elevator multiple control device to again after the command signal received is handled;Elevator multiple control device handle, which is received, to be come from Embedded processor is fed back to after the signal of embedded processor, processing;Embedded processor handle is received from elevator group controlling Send liquid crystal display 2 after the signal of device, processing to.
The intelligent external calling device of the elevator also includes the infrared thermal imagery sensor being arranged in car, and is arranged at bottom Demographics device in plate 1, infrared heat sensor is connected with demographics device by CAN, demographics device with it is embedded Processor is electrically connected with.
Infrared thermal imagery sensor can gather image and temperature information, and thermal image information, the infrared thermal imagery sensor is installed At the top of car medial surface.
The demographics device is microprocessor, and microprocessor can be by the thermal image that is gathered to infrared thermal imagery sensor Information obtains the statistics of number by the processing of rim detection.
Rim detection (object separation) is to Target Segmentation, and all rapidly, marginal point can be identified as registration and identification The location of pixels of gray level mutation.Thermal image is obtained by infrared sensor, each different human body is obtained using rim detection Border, to realize the counting to human body.
After each elevator door is shut, infrared thermal imagery sensor gathers a thermal image information, and is transferred to elevator operation side To next layer of demographics device, number in car is counted after demographics device processing, and on elevator traffic direction External calling device multi-media display on it is upper show, if there is no the action for switching car door, infrared heat on traffic direction As sensor, demographics device are without task again.
Multi-media display shows the instant stop of elevator or operation floor, while number in lift car is displayed that, The convenient passenger for waiting ladder understands number in car immediately, helps passenger to judge immediately and selects elevator ride fewer in number, Reduce waiting time.The present invention uses infrared thermal imagery sensor rather than infrared pulse counter, can reduce demographics Error, it is ensured that accuracy.
Also include the weighing device for being placed in cage bottom, real-time statistics elevator loading, prompting residue loading capacity.Weighing device It is electrically connected with embeded processor.The weighing device is pressure sensor.
Terraced people can be pointed out to wait in advance, and now whether weight is overweight in lift car, helps passenger to judge selection early, carries High user's boarding experience.
Holder holds the IC-card of control elevator operation, and IC-card is inserted into button swiping card part 3, and a kind of situation is stored up for IC-card There is the authority of holder, the authority includes floor authority, time authority, number of times authority etc., such as the card, which have recorded, holds The authority of people's first is in this moon in March, 2015 daily 8:00am~9:00pm can use the card control elevator to reach 5 layers of building, when then the card cancels to April.
When elevator is not responded to, embeded processor makes prompting after according to circumstances handling in liquid crystal display 2, such as When authority has failed, point out in liquid crystal display 2 " authority of swiping the card failed ", do not rung when elevator card-punching system is out of order At once, " failure of swiping the card please use outgoing call button " is pointed out in liquid crystal display 2, at this moment embedded processor can open button brush The authority of clamping part 3, user can use by outgoing call key component 4 to call elevator.When elevator runtime is out of order, Shown " elevator faults please use other elevators " in liquid crystal display 2, user can go to call other elevators.
Another situation is that holder has forgotten band IC-card, or also external personnel need to use elevator, at this moment, pass through The use password of holder or Migrant women elevator is informed in advance, and the password can be set under certain time and number of times Effectively, Migrant women or holder can input password to control the uplink and downlink of elevator on code keypad 6.
