tbusiness.
Intelligent instrument state comprises: instrument remaining sum, supplement number of times with money, the cycle adds up consumption, valve state, battery electric quantity, whether super stream, whether be in high pressure, whether be subject to magnetic interference, whether time-out, valve abnormal information, force pass valve etc.
In step S2, intelligent instrument is in the first manual intervention uplink time section, and in an initial condition, intelligent instrument is in unsorted state, the dormancy time T that after information upload completes one section of intelligent instrument is fixing
x1, wherein, dormancy time T
x1comprise intelligent instrument to concentrator, concentrator to the communication time of main website management system, but does not comprise the communication time of intelligent instrument to repeater, because under unsorted state, main website management system does not also know whether intelligent instrument is connected with repeater; If be in ordered state, each intelligent instrument has judged whether repeater information according to the sequencing information of oneself, and determines its sleep time further, if non-relay device information, then this sleep time is T
x1if there is repeater information, then this sleep time is T
x1+ T
rEG, wherein, T
rEGfor intelligent instrument is to the communication time of repeater, after this intelligent instrument dormancy a period of time, enter accepting state.
In step S2, if intelligent instrument receives the time of reception T of return message at intelligent instrument
rin, intelligent instrument receives the return message that main website management system sends, then continue in step S3 and step S4 after execution, this intelligent instrument is in dormant state always.
In step S3, intelligent instrument process its receive return message, the wireless communication module of this intelligent instrument is in dormant state, and its dormancy time is by the processing time T of intelligent instrument process return message
x2determine, after intelligent instrument processes return message, terminate dormant state, perform step S4.
The return message that in step S3, intelligent instrument receives comprises: information of opening an account, charging information, Query Information, price modification information, synchronous clock information, valve opening information, pass valve information etc.
In step S4, intelligent instrument returns response message to main website management system, and this intelligent instrument sends the time of return T of response message
s2automatically determined by the length of intelligent instrument according to return message, intelligent instrument automatically enters park mode after sending response message.
The response message that in step S4, intelligent instrument returns comprises the information such as device id, ordered state, timeslice ID, intelligent instrument single automatic uplink time ID, intelligent instrument state, instruction executing state.
