Abstract

The invention relates to a wireless data processing method, wireless transmitting equipment and wireless receiving equipment. The method comprises the steps of obtaining encoded data obtained after encoding processing, wherein the encoded data is encoded output data corresponding to data to be transmitted; and expanding the encoded data into feature character data, wherein the feature character data is used for carrying out modulation and wireless transmission processing. The encoded data outputted after the traditional encoding is expanded into the feature character data through adding enhanced encoding processing in the process of data transmission, and then the feature character data is modulated and outputted, so that when signals are disturbed during the wireless transmission in the air and have error codes, the error codes can be corrected when the demodulated feature character data is correspondingly restored to the encoded data so as to reduce the error rate to the greatest extent, thereby greatly reducing the probability of an error caused by the error codes in the data transmission process, being conducive to the application of wireless communication in a long-distance and great-disturbance communication environment of an elevator shaft, and reducing the communication cost.

Description

technical field [0001] The present application relates to the technical field of communication, in particular to a wireless data processing method and a wireless sending and receiving device. Background technique [0002] With the development of communication technology, wireless communication technology has continuously made breakthroughs and become increasingly high-speed and efficient since its birth. The application range of wireless communication technology covers all aspects of social production and life, such as the application of public mobile communication, private network communication and home wireless network. Among them, in the field of elevator equipment, wireless communication technology is an indispensable basic technology for daily operations such as elevator calling and position monitoring during the operation of elevator equipment. The traditional wireless communication system applied to elevator equipment is composed of a sending end and a receiving end....
