Example 1.
The Walk by meter reading method described in this embodiment includes a hand-held device and an intelligent meter, where the hand-held device has two wireless transceiving channels, the first wireless transceiving channel is used to wake up the intelligent meter and the second wireless transceiving channel is used to collect data, and the two transceiving channels can work simultaneously and do not affect each other; the intelligent meter comprises a third channel for receiving and transmitting data; the second wireless transceiving channel and the third channel have a Mesh-structured network communication protocol; the meter reading is carried out according to the following steps:
a. the handspike device moves back and forth between the intelligent meters and sends a wake-up signal through the first wireless transceiving channel to wake up the intelligent meters;
b. and a Mesh network is formed among the awakened intelligent meter, a second wireless transceiving channel of the hand-copying device and the awakened intelligent meter, and the data is forwarded through the meter routing and the data of the intelligent meter is forwarded to the hand-copying device.
c. The handsheet device arranges an intelligent meter list to be collected in the Mesh network according to the meter route;
d. the awakened intelligent meter sends data to an adjacent intelligent meter through a Mesh network, and the adjacent intelligent meter receives the sent data, packages the data with the data of the meter and waits for a unicast data acquisition instruction of a meter reader;
e. the hand-copying device randomly selects an intelligent form broadcasting data acquisition instruction from the sorted intelligent form list, and the selected intelligent form reports the data packaged in the form after receiving the instruction;
f. and e, after receiving the packed data, the hand-copying device analyzes and deletes all the intelligent meters with the obtained data from the intelligent meter list needing to be collected, renews the intelligent meter list needing to be collected and continuously repeats the step e.
During specific work, the work flow of the handsheet is shown in fig. 4, and the work flow of the smart meter is shown in fig. 5. During operation, as shown in fig. 1, an operator carries the handspike device on the road, and simultaneously the handspike device sends a wake-up signal and broadcasts an acquisition instruction to wake up the intelligent meter in the coverage range of the first wireless transceiving channel. The Mesh networking of the awakened smart meters is shown in fig. 2, and the smart meters can forward data to each other through the Mesh network, so as to enhance the coverage range during data transmission, especially the coverage range of the hand-copy device. And when networking is carried out, the handsheet device arranges the list of the intelligent meters to be collected. And the smart meter directly starts to broadcast the data of the smart meter to the adjacent smart meters as shown in fig. 3, and after receiving the data broadcast by the adjacent smart meters, the smart meter fuses and packs the data of the smart meter and the received data of the adjacent smart meters into a data packet and waits for an acquisition instruction of the hand-reader.
