Embodiment Construction

[0007] Install the wireless collector near each user table to form a system with the table. In order to avoid data confusion or loss during meter reading, the wireless handheld unit is used as the host, and the wireless collector is used as the slave. Before meter reading, the host sends the address code as a call, and the slave with the corresponding address code receives the call. Compress and pack its own address code and data and send it to the host. The host will verify the returned address code after decompressing the data packet. If the verification passes, the data will be stored in the corresponding memory, otherwise it will be discarded. When reading the meter, after receiving a user data, the wireless handheld unit will automatically query the next user data until it finishes querying the nearby users.

Abstract

The invention discloses a wireless meter checking system based on an FPGA (Field Programmable Gate Array) and a low power-consumption RF (Radio Frequency) chip CC1100, which mainly comprises two parts, one part is a wireless handheld unit consisting of the FPGA and the low power-consumption RF chip CC1100, and the other part is a wireless acquirer consisting of an ultra-low power-consumption MSP430 series singlechip and an RF chip CC1100. The wireless handheld unit is mainly used for completing functions of reading data of the wireless acquirer and storing the data, carrying out human-machine interaction with workers, and the like. The wireless acquirer is used for completing functions of receiving query information of the handheld unit and then reading sheet information and sending the sheet information to the wireless handheld unit, and the like.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a wireless meter reading system based on FPGA and RF technology. Background technique [0002] The wireless meter reading system is generally composed of concentrators and collectors (collection terminals), as well as communication channels and meter reading software. Downlink channel, the current uplink channel is long-distance data transmission, generally there are telephone dial-up, GPRS (GSM or CDMA), etc. The transmission reliability and technical difficulty are not the main problems in meter reading. The key to community meter reading lies in the downlink channel. It is also the most difficult part of meter reading. At present, according to the different downlink communication channels, there are power carrier, RS485 bus, Ethernet, cable TV network and so on. The RS485 bus method is to connect the concentrator and the collector through the RS485 bus, and communicate through th...
