Remote control technology is a controlled object of remote control and monitoring technology, is the use of automatic control technology, computer technology and communication technology combined with each other and produced. In the daily life and production, and the application of remote control technology is widely, such as household electrical appliances TV, air conditioning, is the use of remote control on the remote control, power plant generating units of operation monitoring and control, but also the use of remote control technology.

Now the development of elevator industry has come to a relatively saturated state, in the mechanical structure, electrical components is already quite mature, but the elevator is in order to facilitate people's daily life and production, so there are many details of the innovation, or the potential for development of.

The remote control technology can be classified into wired and wireless remote control technology according to the channel medium. The main subject of this paper is the application of wireless remote control technology in elevator. The development of the automotive industry has led to the birth of the car elevator, many cities of the large parking lot, car 4S shop are equipped with a car lift.

Car elevator is actually a special point of the cargo lift, if in accordance with the traditional truck lift to do the car lift, which is clearly not enough. According to the usual to use the elevator, we want to use the elevator. The first is to the car outbound ladder, elevator leveling opened the door, then we got into the car, then by car in the control box on the target floor choice, finally is to arrive at the destination floor, leave the elevator. But the car, is not the same, although the car of elevator car is to be much larger than the ordinary cargo elevator, under a parked car is no problem, but the car into the car can open the door is not necessarily. So want to like the ordinary elevator ride as in the cage layer there is a problem, driver from the car use control box is too much trouble to and from the car down is not very convenient, and the other one is, in the elevator call elevator also require the driver from the car stuck his body to operate or down from the car, which is to use inconvenient. Through the use of remote control technology, the problem can be solved completely in the elevator.

A receiving device by a user's hand remote control device and the communication can be completed action, by users according to the different remote control button that sends different signals, the receiving device receives the signals of different make different actions and the corresponding relay is provided in the elevator car. The output terminal of the relay is connected with the control box button of the elevator, and the receiving device directly controls the elevator control box to complete the call. In the hall, according to the remote control of the car in the floor of the floor corresponding to the button, enter the elevator after the target floor button in the remote control.

There are many ways of wireless communication, which have different characteristics, such as communication distance, communication efficiency, anti-interference ability and so on. Because receiving device is installed in the control box, and the control box is formed by the metal, the receiving device is put in, the signal will be affected by the control box, and when the car in car outbound ladder, transmitter and receiver and the hoistway wall or floor separated, affect the signal. So need to adopt corresponding measures to ensure the reliability of the signal connection, such as increasing the transmitting power of the equipments, receive sensitivity, or can will receive antenna device is introduced, at the top of the car and the car placed a, so that the signal is to completely cover the whole well.

After the remote control technology is integrated into the elevator, it makes the use of the automobile lift more convenient and more user-friendly. The emergence of housing, car will make more extensive use of car of elevator, remote control technology used in elevator cars will also increasingly common, every household will be the car through the elevator cars delivered to his doorstep, if want to ordinary elevator that is absolutely can not adapt to the needs of the market, sooner or later is to through the corresponding method to make improvements to make it more convenient for the user's daily use.
