Remote control and monitoring technology is a controlled object for a long distance is the use of technology, automatic control technology, computer technology and communication technology are combined to produce. In the daily life and production, the application of remote control technology widely, such as household appliances TV, air conditioning, control is the use of remote control to the remote operation, monitoring and control of turbine power plant, but also the use of remote control technology.

The development of the elevator industry now has reached a relatively saturated state, the mechanical structure, electrical component is already quite mature, but the elevator is for the convenience of people's daily life and production, so there are a lot of details or innovation has great development potential.

Remote control technology can be divided into wired remote control and wireless remote control according to the channel medium. The theme discussed in this paper is mainly the application of wireless remote control technology in elevators. The development of the automobile industry has prompted the birth of the car elevator, and many large parking lots and 4S stores in the city are equipped with car elevators.

The car elevator is actually a special carrier elevator, which is obviously deficient if the traditional elevator is used to make a car elevator. According to the usual use of the elevator is concerned, we should use the elevator, the first is to call the car after the staircase, elevator leveling opened the door, and then we entered the car, and then through the control box in the car on the target floor, the last is to reach the target floor, leaving the elevator. But after changing into a car, it is different. Although the car elevator car is much larger than the ordinary elevator, there is no problem that it can accommodate a car, but whether the car can open the door after entering the car is not necessarily. You want to take an ordinary elevator like that in the car the layer selection is a problem, the driver from the car use control box more trouble, and down from the car is not very convenient, there is another call, also need the driver to operate out from the car body to or from the car down in the elevator it is also used to reflect, not convenient. Through the use of remote control technology, this problem can be solved completely in the existence of ordinary car elevators.

A receiving device is arranged in the elevator car, through remote communication with the users to complete the action, the user through the remote control button according to the different sounds of different signal after receiving different signal receiving device to make different movements, making the corresponding relay. The output end of the relay is in parallel with the control box button of the elevator, and the receiving device can directly control the elevator control box to complete the call ladder action. When outside the hall, press the button of the floor number of the floor of the car in the remote control, and then press the button of the target floor in the remote control after entering the elevator.

There are many ways of wireless communication. Different modes of communication have different characteristics, such as communication distance, communication efficiency, anti-interference ability and so on. Because the receiving device is installed in the control box within the control box, and is made of metal, the receiving device placed in the signal will be affected by the control box, and when the car in the car outside the ladder, and well wall or floor space between the transmitter and the receiver will affect the signal. So it is necessary to take appropriate measures to ensure the reliability of the signal connection, such as increasing the transmission power and equipment receiving sensitivity, or can be led out the antenna receiving device, in the car and the car roof placed a, the signal can completely cover the whole well.

After the remote control technology is integrated into the elevator, the use of the car elevators tends to be convenient and humanized. The car will also make use of residential elevator car is more wide, using remote control technology in the car in the elevator will be more and more common, every family will put the car through the car lift to his own home, if you want to lift that ordinary is absolutely unable to adapt to market demand, sooner or later is through the corresponding method to make improvements to make it more convenient for the users of daily use.
