The Design Of A Ultra-low Power Wireless Remote Meter Reading Network Based On The Internet Of Things

Compared with the IC card gas meters, direct reading remote transmitting gas meters which basdon the Internet of Things can measure the flow directly and transmit the flow to a remote server, toavoid human manipulations and the loss of IC cards, and convenient the modification of the valuation.However, since the RF circumstance of the remote transmitting gas meters are complex, and thetopologies of the network of gas meters are not fixed, there are difficulties in the design of RFtransition and the networking of the remote transmitting gas meters. The Lack of outer power supplyalso make the power consuming of the meter design even difficult.In this paper, we designed a structure of the network of direct reading remote transmitting gasmeter which the Internet of Things, including the nodes of meters and a sink. We designed aMR-MAC based on a waking up schedule, and compared it with S-MAC on OPNET. The simulationsof OPNET show the advantages of MR-MAC in real time feature and power consuming. We alsorealize the MAC base on a TI CC1100e platform, and discussed the relationship between theparameters of the waking up schedule and the power consuming.Based on the MAC, we design the protocols of the network to perform the reading and valvecontrolling of the meters, including the definition of the frames and activities of the protocols. We alsodesigned the meters and sink on the platforms of TI MSP43, including the reading, transmitting, theHID and power control of the meters as well as the design of GPRS transmitting on a sink.We carried on a series of tests and verifications of our design in real circumstance, and developedsolutions for different environments. The success rate of meter reading and power consuming are testand calculated. The tests turned out to verify the soundness and validity of our design. In the last partof the paper, we also discuss about the future works, including the design of a handheld readingsystem, the building the remote server, and the design of RF repeaters in the network.
