Embodiment 1

[0069] In this embodiment, a meter reading tool and a meter-reading main control board form a wireless remote transmission signal transmitting and receiving terminal. Set the meter number read by the meter reading tool to 2016082614, send the meter reading signal in accordance with the "Shanghai Wireless Remote Transmission Protocol 1.0" format, and send the meter reading signal every five seconds. The receiving end should synchronize to the meter number, and recognize the real data behind the meter reading signal, and return a feedback signal that the meter reading is successful. After the meter reading tool receives this feedback signal, it indicates that the meter reading is successful.

[0070] figure 1 For the core of the inventive method, to synchronously output the meter number, there must be a comparison meter number compared with the code stream received, and the comparison meter number needs to be determined according to the data format and data protocol of the meter...

Abstract

The invention discloses a reliability method of processing a wireless tele-transmission air code stream. In the invention, each bit in the code stream is taken as a basic unit of code stream receiving and data processing, needed data can be synchronized in an air data flow signal and a synchronization code can be freely set according to a transmitting terminal protocol. After a wireless module receives and analyzes an air signal and generates a data flow signal, according to a data protocol of a wireless tele-transmission transmitting terminal, a receiving terminal sets a synchronization code and carries out data synchronization identification on the data flow signal. Once the data is correctly synchronized and real data behind the synchronization code is identified, the receiving terminal returns a feedback signal expressing that the real data is correctly received. The synchronization code is a table tool number during real exploitation and can be used in different numbers of different occasions. By using the method of the invention, a synchronization code stream of a series of data code streams can be synchronously identified so that receiving, storage and feedback of the real data can be realized.

Description

technical field [0001] The invention belongs to the technical field of wireless signal transmission, relates to an algorithm for data processing and analysis, and in particular to a reliability method for processing wireless remote transmission air code streams. Background technique [0002] At present, most areas in China use manual meter reading. This method of door-to-door meter reading by staff leads to a huge workload, and cannot guarantee the accuracy and timeliness of data, which increases the cost of meter reading and directly affects gas consumption. Company benefits. The development of informatization promotes the emergence of automatic meter reading systems. The existing automatic meter reading solutions are mainly through the laying of wired cables, but the complex real environment places great restrictions on laying cables, and existing communities need to re-lay cables. unrealistic. The wireless meter reading solution can effectively transmit data and avoid t...
