Method for communication between collector and concentrator of wireless remote meter reading system

Abstract

The invention discloses a method for communication between a collector and a concentrator of a wireless remote meter reading system, which can not only greatly reduce the cost of a wireless remote meter reading system but also be quite convenient for increasing a new collector. The method comprises the following steps: firstly, whether an increased collector is in the wireless communication rangeof a concentrator or not is judged; if not, the collector is used as a forwarding station; after the forwarding station receives a power data forwarding request and permits to forward power data, theincreased collector transmits the power data to the forwarding station; when the concentrator integrally receives the power data of the increased collector, which are transmitted by the forwarding station, the concentrator transmits receiving confirmed information to the forwarding station; after receiving the receiving confirmed information, the forwarding station transmits the receiving confirmed information to the increased collector; if the increased collector does not receive the confirmed information in a certain time limit, the increased collector requests that the power data are retransmitted; and when the concentrator does not receive the power data of the increased collector all the time, the concentrator gives an alarm.

Description

Communication method between collector and concentrator of wireless remote meter reading system Technical field The invention relates to the technical field of wireless remote meter reading systems, in particular to a communication method between a collector and a concentrator of a wireless remote meter reading system. Background technique At present, the communication between the collector and the concentrator of the wireless remote meter reading system is mainly wireless communication. Because wireless communication itself has the advantages of flexible networking and simple wiring, it has been widely used. However, in wireless communication, because the current The transmission distance of the wireless technology with moderate cost performance is limited, that is, the wireless signal coverage is limited. With the expansion of the power supply scale, the number of users is increasing. In this way, it is necessary to continuously increase the collectors to provide services to ...

Problems solved by technology

At present, the communication between the collector and the concentrator of the wireless remote meter reading system is mainly wireless communication, because wireless communication itself has the advantages of flexible networking and simple wiring, so it is widely used, but in wireless communication, because the current The transmission distance of the wireless technology with moderate cost performance is limited, that is, the wireless signal coverage is limited, and with the expansion of the power supply scale, the number of users is increasing. In this way, it is necessary to continuously increase the number of collectors to provide services for more users. Therefore, there may be an increase in the location of the collector because it exceeds the coverage of the wireless signal of the concentrator, so that the additional collector cannot establish communication with the original concentrator. At present, the means to solve the above problems is mainly to increase the concentrator. Quantity, so that the wireless signal of the concentrator covers all areas (the area where the collector has been installed and the area where the collector is expected to be installed in the future), this will greatly increase the cost of the wireless remote meter reading system, and secondly, because of the need to consider The wireless signal coverage of the concentrator and the addition of new concentrators, so a variety of requirements must be taken into account when adding collectors, that is to say, adding collectors is inconvenient and reduces construction efficiency
