Meanwhile, the method of full coverage calling is adopted, so that the requirement of 'micro-power radio equipment management regulation' can be met, the energy consumption of the water meter is reduced, and the service time of a battery is prolonged. A low-power consumption wireless communication meter reading method of a wireless meter reading system based on intelligent water affairs,

and the meter reading APP is used for carrying out close-range communication meter reading on the water meter with unified remote meter reading failure.
Further, the step of performing meter reading channel occupation frequency for meter reading APP communication control specifically includes:
s11: the meter reading APP obtains a frequency-occupied area of a channel to be meter-read from a server;
s12: under the condition that the meter reading machine is in the frequency-occupying area in the step S11, the meter reading APP obtains the preset frequency-occupying set by the staff;

Further, the steps for performing meter reading full coverage calling meter reading by the meter reading APP communication control are specifically as follows:
s21: the meter reading APP acquires a meter reading list; and establishing a communication relation with the meter reading machine;
s22: the meter reading APP sends a request for starting a calling program and the calling data to the meter reading machine; the meter reading machine performs full coverage calling;

s24: the meter reading APP sends unified meter reading data to all the water meters through the meter reading machine; the unified meter reading data at least comprises automatic wake-up time, automatic meter reading calling frequency, each automatic calling time, adjacent two automatic calling interval time and automatic meter reading calling times.
After the calling program is started, the full-coverage calling is realized through the meter reading machine, unified meter reading data is sent to the water meters after the water meters are awakened, all the water meters are designated to wake up at a certain set time point, calling frequency, calling interval time and the like of the water meters are uniformly set, so that the work of all the water meters is kept in pace, the water meters only need to wake up in a designated time range, the number of water meter degrees is uploaded, the time is not needed, and the power consumption of the water meters is effectively reduced.
In the new micro-power radio equipment management regulation, the duration of single transmission is not more than one second, the transmission frequency of the meter reading machine is greatly increased, the power consumption of the water meter is also greatly increased, but after full-coverage calling is adopted, all the water meters are only required to be in a high-energy-consumption working state when being called for the first time, and after uniform working steps, the water meters can be collected in an endless manner only by short working time. Under the background of the latest communication regulations, the design scheme can finish meter reading work under the condition of the high-standard communication regulations without changing batteries of the original water meters or even the water meters.
Still further, the call data at least includes a call frequency f, a call period T of each round, a number of calls C of each round, a total number of calls C, a time T of each call, an interval time δt between two adjacent calls, and a start delay time δt of each round;

Each meter is periodically operated for a short period of time, and the time of operation of each meter is random in one area. The meter reading machine is alternately operated in working signal period and dormant period. With the duration of a single transmission under the newly prescribed conditions not exceeding one second, i.e. the meter reading machine operating signal period cannot exceed one second. Therefore, the water meter can only receive the working signal to execute corresponding operation when the working time falls within the single working signal period of the meter reading machine, and other water meters are in a dormant state anyway, so that the expected operation cannot be realized. The meter reading machine is used for carrying out full-coverage calling to carry out multi-round calling design on the water meter, after one round of calling is completed, a period of dormancy time is delayed to be executed, and then the next round of calling is executed, so that when the next round of calling is carried out, the dormancy time period of the previous round of calling can be covered by a part of signal time period of the next round of calling, and after the whole working period of the multi-round calling water meter is covered by the signal time period, the full-coverage calling is realized, and all water meters are awakened.
According to still further technical scheme, the method for realizing unified remote meter reading by the communication control of the regional water meter through meter reading APP communication comprises the following steps: after the automatic wake-up time is set in the unified meter reading data, the meter reading APP drives the meter reading machine to send out meter reading signals according to the automatic meter reading period and the automatic meter reading calling frequency, and the meter reading list with the acquired water meter degree is transferred into the meter reading list.
The automatic wake-up design is realized, and the water meter data can be obtained and transmitted only by sending a lora signal by the meter reading machine.
According to still further technical scheme, the steps of performing close-range communication meter reading on the water meter with unified remote meter reading failure by the meter reading APP are as follows:
after the meter reading APP starts the meter reading program and after waiting for an automatic meter reading period, if the water meter number still exists in the meter reading list, waiting for a worker to start the close-range meter reading program;
the meter reading APP obtains the operation of clicking the water meter number in any meter reading list by workers, and obtains a close-range meter reading starting signal;
the meter reading APP enters a water meter calibration module page, and displays the environment picture, remark description information, address and address map of the current water meter;
when the meter reading APP obtains the operation that a worker clicks an address map, third-party navigation software is started, and meter reading navigation is performed by taking the current position of the worker as a starting point and the position of a water meter as an end point;
and when the staff reaches the close range, the meter reading APP performs close range communication meter reading.
By adopting the scheme, even if meter reading cannot be realized at a long distance, the meter reading at a shorter distance can be realized by quickly reaching the periphery of the water meter through navigation.
Compared with the prior art, the invention has the beneficial effects that:
compared with the micro-power (short distance) radio equipment management regulation before revision, the invention meets the regulation that the single emission duration time in the new regulation is not more than 1 second, solves the problem of short service life of the water meter caused by high power consumption under the condition of frequent signaling, and unifies the working steps of the water meter in one area through full coverage awakening, so that all the water meters can awaken at the same time, and the data of the water meter can be rapidly fed back through the excitation of a meter reading machine, thereby realizing rapid and synchronous meter reading, shortening the feedback working time of the water meter and greatly reducing the energy consumption caused by subsequent meter reading. And each area occupies frequency in advance, so that the interference to other equipment is effectively avoided, and meanwhile, the condition of random acquisition of meter reading is avoided. The whole meter reading system design can reach the new standard without modifying the structure of the water meter, etc., and can reduce the energy consumption of the water meter and prolong the working time of the water meter.
