That is, when the key swiping component 3 is abnormal, the function of restoring the traditional outbound key is played. When the key swiping component 3 functions normally, the circuit between the embedded processor and the outbound button 4 is disconnected. When the key swiping component 3 is abnormal, the circuit between the embedded processor and the outbound button 4 is connected.

The embedded processor collects elevator information from the elevator group control system in real time, and displays elevator up, down, arrival, floor and other information. At the same time, information such as time, temperature, humidity, weather/air quality and other information are collected from the clock, temperature sensor, air particulate matter collector and other devices. Supports the playback of multimedia content such as promotional pictures, advertisements, and videos.

Embedded processor, when the function of the key swiping component 3 is normal, it accepts the call information of the key swiping component 3 and forwards it to the elevator group control device after processing, so as to control the elevator up, down and stop while not accepting the information from the outgoing call button component 4 . When the function of the key swiping component 4 is abnormal and the call information cannot be transmitted, the call information of the outgoing call key component 4 is accepted, and after processing, it is forwarded to the elevator group control device to control the elevator up, down, and stop.

The liquid crystal display screen receives the instruction signal input by the user, and the instruction signal is transmitted to the embedded processor. The embedded processor processes the received instruction signal and then transmits it to the elevator group control device; the elevator group control device receives it The signal from the embedded processor is processed and fed back to the embedded processor; the embedded processor transmits the signal received from the elevator group control device to the liquid crystal display 2 after processing.

The intelligent outbound call device of the elevator also includes an infrared thermal image sensor arranged in the car, and a people counting device arranged in the bottom plate 1. The infrared thermal sensor and the people counting device are connected through the CAN bus, and the people counting device is connected with the embedded The processor is electrically connected.

The infrared thermal image sensor can collect images, temperature information, and thermal image information. The infrared thermal image sensor is installed on the top of the inner side of the car.

The people counting device is a microprocessor, and the microprocessor can obtain the statistics of the people by processing the thermal image information collected by the infrared thermal imaging sensor through edge detection.

Edge detection (object separation) segmentation, registration and recognition are very fast, and the edge point can be identified as the pixel position of the gray level mutation. The thermal image is acquired through the infrared sensor, and the boundary of each different human body is obtained by edge detection, so as to realize the counting of the human body.

Each time the elevator door is closed, the infrared thermal image sensor collects thermal image information and transmits it to the people counter on the next floor of the elevator running direction. After processing, the people counter counts the number of people in the car, and then moves it in the elevator running direction. It is displayed on the multimedia display of the outbound call device on the computer that if there is no action of opening and closing the car door in the running direction, the infrared thermal image sensor and the people counting device do not need to work again.

The multimedia display shows the elevator's immediate stopping or operating floor, and also shows the number of people in the elevator car, which is convenient for waiting passengers to know the number of people in the car instantly, helping passengers to make real-time judgments to choose elevators with fewer people, reducing waiting time . The invention adopts an infrared thermal imaging sensor instead of an infrared pulse counter, which can reduce the error of people counting and ensure accuracy.

It also includes a weighing device placed at the bottom of the car, which counts the elevator load in real time and prompts the remaining load. The weighing device is electrically connected with the embedded processor. The weighing device is a pressure sensor.

It can prompt the waiting person in advance whether the weight in the elevator car is overweight at this time, helping passengers to make early judgments of choices and improving the user's riding experience.

The cardholder holds an IC card that controls the operation of the elevator and inserts the IC card into the button swiping component 3. In one case, the IC card stores the cardholder's authority, which includes floor authority, time authority, frequency authority, etc., for example The card records that the cardholder A’s authority is that in this month of March 2015, the card can be used to control the elevator to reach the 5th floor of the building from 8:00 am to 9:00 pm every day. When it comes to April, the card is invalid.

When the elevator does not respond, the embedded processor will prompt on the LCD 2 after processing according to the situation. For example, when the authorization has expired, the LCD 2 will prompt "the credit card authorization has expired", when the elevator credit card system fails and there is no response , The LCD 2 prompts "card swiping failure, please use the outbound button", then the embedded processor will open the authority of the button swiping component 3, and the user can use the outbound button 4 to call the elevator. When the elevator operation system fails, the LCD display 2 displays "Elevator failure, please use another elevator", and the user can call other elevators.

Another situation is that the cardholder forgot to bring the IC card, or there are outsiders who need to use the elevator. At this time, the cardholder or outsiders need to use the elevator password in advance, and the password can be set at a certain time and It is valid under the number of times. Outsiders or cardholders can enter a password on the password keyboard 6 to control the elevator's upward and downward movement.
