 An elevator intelligent control system, comprising: a sensor module, a controller and a host computer, the sensor module and the controller are respectively installed in the elevator car, the sensor module and the controller are electrically connected, and the host computer is installed in the control machine room and electrically connected to the controller.
 The sensor module includes pressure sensor, magnetic sensor, infrared sensor, temperature and humidity sensor,
 The pressure sensor is used to detect whether the pressure value of the car exceeds the preset pressure value to avoid overweight; the magnetic sensor is used to detect the specific floor of the elevator and feedback the information to the controller; the infrared sensor is used to detect the specific number of people in the car and feedback To the controller; the temperature and humidity sensor is used to detect the temperature and humidity in the car and send it to the controller.
 In one of the embodiments, the elevator intelligent control system further includes an identity recognition module, and the identity recognition module is installed on the elevator door. In order to prevent non-maintenance personnel from entering after the elevator fails, an identity recognition module is set up to identify the maintenance personnel who need to carry out the faulty elevator. The identity recognition module includes face recognition, fingerprint recognition, RFID recognition, and the identified identity The information is compared with the information stored in the controller. If the information matches, the controller will control the elevator door to open and allow entry. If the information does not match, the elevator door will not be allowed to enter.
 A control method for an elevator,
 In the first step, the user sends a signal to obtain elevator information to the host computer;
 In the second step, the host computer sends a signal to obtain elevator information to the controller;
 In the third step, the controller sends the elevator information to the host computer; the elevator information includes the location information of the elevator and the time information of arriving at each floor;
 The fourth step, the upper computer sends the elevator information to the user;
 Step 5: The user sends information about taking the elevator to the host computer;
 Step 6: The user sends the information that the user has taken the elevator to the host computer.
 When the user wants to take the elevator, he sends a request to obtain all the elevator information of a building to the host computer. After obtaining the request sent by the user, the host computer sends a signal to obtain the elevator information to the controller. The location information and the arrival time information of each floor are sent to the host computer, and the host computer sends all elevator location information to the user, and the user determines which elevator to take at what time according to the location information of each elevator and the time information of each floor arrival , and send the information of taking the elevator to the host computer. After taking the elevator, send the information of the elevator that has been taken to the host computer. For example, scan the QR code in the elevator car, and pass the QR code to send the elevator information Send it to the controller, the controller then sends the information sent by the user to the host computer, and the host computer can determine which elevator the user has taken according to the information sent by the specific controller and communicate with the user to send the information sent by the elevator. Make a record after the comparison.
 It can be understood that the information sent by the user to the host computer to take the elevator can be general information or specific information. For example, it can send information to the host computer that the elevator will be taken immediately, or which elevator to take at a specific time.
 For example, there are 4 elevators in a building, namely elevator No. 1, elevator No. 2, elevator No. 3 and elevator No. 4. The user on the 20th floor sends a signal to obtain the information of elevator No. The controller of elevator No. 4 receives the floor information and the estimated arrival time of a certain floor to the user. In the elevator information, it finds that elevator No. 2 on the 22nd floor will arrive at the 20th floor in 1 minute. The user sends a message to take elevator No. 2 After the user takes the No. 2 elevator, scan the QR code in the No. 2 elevator car to send the information of taking the No. 2 elevator to the controller in the No. 2 elevator, and the controller sends the riding information to the The upper computer, the upper computer compares the riding information sent by the user with the information that has already been taken, and then makes a record.
 In the elevator intelligent control system and control method described above, the user obtains the floor information of all elevators in the building and the time information of the arrival time of each floor through the controller and the host computer in the elevator, so that the user can arrive at the designated elevator according to the time he takes the elevator. Elevator rooms on different floors reduce waiting time for elevators, save time and improve efficiency.
 Furthermore, the user can send information about the floor and time of taking the elevator to the host computer, and the host computer recommends the most suitable elevator to the user according to the user's needs.
 In one embodiment, in order to facilitate the user to choose a suitable elevator to take, the elevator information further includes information on the number of passengers in the elevator.
 In this way, after the user obtains the information on the number of people in the elevator sent by the host computer, he can choose which elevator to take based on the actual number of people in the elevator at present. There are a lot of people in the elevator and the elevator that is about to be fully loaded can be used to quickly reach the first floor without stopping in the middle, which improves the efficiency.
 In one of the embodiments, in order to reduce elevator faults, the elevator information further includes temperature and humidity information in the car.
 The equipment in the elevator, for example, if the motor works in the abnormal temperature and humidity range for a long time, the probability of failure will increase. Therefore, through the temperature and humidity sensor in the car, the temperature and humidity around the elevator can be monitored, and the temperature and humidity The value is sent to the controller for comparison. If the temperature and humidity value is within the preset range, the elevator is normal. If it is not within the preset range, the information will be sent to the host computer. The elevator maintenance personnel will maintain the elevator after obtaining the abnormal information. , to ensure that the elevator runs under normal temperature and humidity, which can reduce the occurrence of elevator failures.
 In one embodiment, in order to facilitate the user to take the elevator, the elevator information further includes elevator failure information. The elevator fault signal includes information about which elevator has a fault and specific fault information.
 The specific information about which elevator has failed is sent to the user. For example, after get off work, the building user receives the information sent by the host computer that the No. 3 elevator has broken down and cannot be used. Usually, there are 4 elevators working, but now the No. 3 elevator has broken down, and only 3 elevators are working. The number of customers will definitely be affected. Users can plan better and arrange to arrive earlier than usual to avoid being late.
In one of the embodiments, before the first step, the host computer sets the user's authority.
 In one of the embodiments, a user who has obtained a certain authority can request the elevator to reach a specified floor.
 When a user applies for registration, the authority is divided for different users. For example: ordinary users and advanced users respectively, the advanced users have the authority to get the specified elevator to the specified floor.
 The advanced user sends the ride information to the host computer; the ride information includes the floor information of the ride and the number of passengers.
 The host computer sends the elevator information to the controller; the elevator information includes the elevator floor information and the number of people. Select the elevator that matches the walking path and the number of passengers of the advanced user to stop on the floor where the advanced user is located. After the advanced user enters the elevator, the information of the elevator that has been taken is fed back to the host computer through the controller by scanning the code.
 For example, if an advanced user needs to take the elevator on the 18th floor to the first floor, and the number of passengers is 3, then the advanced user will send the above information to the host computer, and the host computer will send the elevator information to the controller, and the controller will send the elevator's floor , driving direction, and the number of people on the floor are sent to the host computer, and the host computer selects the optimal way after obtaining the information. For example, an elevator on the 20th floor just goes down to the first floor, and the current number of passengers is 3, and it is on the 19th floor The host computer will send a control signal to the controller, and the controller will control the elevator to stop on the 18th floor after receiving the information. After the advanced user enters the elevator, he will send the information that he has taken the elevator to the host computer through the controller by scanning the code. .
 Further, if the floor, running direction and the number of elevators of all elevators do not meet the requirements, the upper computer will send information to continue waiting to the advanced user. If the advanced user agrees to continue waiting, the upper computer will be the fastest among all elevators. The empty elevator is controlled to the designated floor of the high-level user. After the high-level user enters the elevator, the information that the high-level user has taken the elevator is sent to the host computer through the controller by scanning.
 In one of the embodiments, in order to ensure that resources are not wasted at will, if the host computer does not receive feedback information after obtaining the elevator information specified by the advanced user within a preset time, it will record the breach of contract.
 The upper computer obtains the information of the senior user taking the elevator, which includes the floor and the number of passengers. The upper computer controls the elevator to reach the designated floor through the controller. After waiting for the preset time, for example, 5 minutes, the upper computer has never received the advanced user’s information. The user's feedback information also believes that the advanced user has breached the contract, and the host computer should make a record. When the number of defaults reaches the preset number, advanced users will no longer enjoy the above privileges. In this way, high-level users can avoid wasting public resources at will.
