a step of carrying out meter reading channel frequency occupation by meter reading APP communication control;
a step for meter reading APP communication control to carry out meter reading full coverage calling;
the method comprises the steps of performing regional water meter communication control to realize unified remote meter reading through meter reading APP communication;
and the step of performing short-distance communication meter reading on the water meters which fail to be uniformly and remotely read by the meter reading APP.
Further, the step of controlling the meter reading APP communication to perform meter reading channel frequency occupation specifically is as follows:
s11: the meter reading APP acquires a frequency occupying area of a channel needing meter reading from a server;
s12: the meter reading APP acquires a preset frequency occupying frequency set by a worker under the condition that the meter reading machine is in the frequency occupying area in the step S11;

Further, the step of performing meter reading full coverage call meter reading by the meter reading APP communication control specifically includes:
s21: a meter reading APP obtains a list which is not read; establishing a communication relation with the meter reading machine;
s22: the meter reading APP sends a call starting program request and the call data to the meter reading machine; the meter reading machine carries out full-coverage calling;
s23: after the meter reading APP continuously calls the full coverage for the preset wake-up time, the step S24 is carried out;
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 awakening time, automatic meter reading calling frequency, each time of automatic calling, interval time between two adjacent times of automatic calling and automatic meter reading calling times.
After the calling program is started, firstly, full-coverage calling is realized through the meter reading machine, unified meter reading data are sent to the water meters after the water meters are awakened, all the water meters are appointed to be awakened at a certain set time point, the calling frequency, the calling interval time and the like of the water meters are uniformly set, all the water meters work in a consistent step, the water meters only need to be awakened within an appointed time range, the water meter degrees are uploaded, time-free working is achieved, and the power consumption of the water meters is effectively reduced.
In the new 'micropower radio equipment management regulation', if the duration of single transmission does not exceed one second, the transmission frequency of the meter reading machine is greatly increased, and the power consumption of the water meter is also greatly increased. Under the background of the latest communication regulation, the meter reading work under the high-standard communication regulation condition can be completed without replacing the battery of the original water meter or even the water meter by adopting the design scheme.
Still further, the call data at least includes a call frequency f, a call period T of each round, a call frequency C of each period, a total number of call rounds C, a call time T of each round, an interval time δ T between two adjacent calls, and an initial delay time δ T of each round;

Each meter is periodically operated for a short period of time, and the operation time of each meter is random within a region. The meter reading machine alternately operates in the signal period and the sleep period. With the duration of a single transmission under the newly specified condition not exceeding one second, the time interval of the working signal of the meter reading machine cannot exceed one second. Therefore, the water meter can receive the working signal only when the working time falls within the single working signal period of the meter reading machine so as to execute the corresponding operation, and other water meters are in the dormant state so as to cause that the expected operation can not be realized. The meter reading machine carries 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 executed in a delayed mode, then the next round of calling is executed, when the next round of calling is carried out, the dormancy time period of the previous round of calling is partially covered by the signal time period of the next round of calling, after the multi-round calling is carried out, the full-coverage calling is realized after the signal time period is covered in the whole working cycle of the water meter, and all the water meters are awakened.
According to a further technical scheme, the step for performing area water meter communication control and realizing unified remote meter reading through meter reading APP communication comprises the following steps: and after the set automatic wake-up time in the unified meter reading data is reached, the meter reading APP drives the meter reading machine to send a meter reading signal according to the automatic meter reading period and the automatic meter reading calling frequency, and the obtained meter reading list of the water meter number is transferred into the meter reading list.
The automatic wake-up design is realized, and the water meter data can be acquired only by sending a lora signal by the meter reading machine for data transmission.
According to a further technical scheme, the step of performing near distance communication meter reading on the water meter which fails in unified remote meter reading by the meter reading APP is as follows:
after the meter reading APP starts a meter reading program and waits for an automatic meter reading period, if no water meter number still exists in a meter reading list, waiting for a worker to start a close-range meter reading program;
the meter reading APP is used for obtaining the operation that workers click the water meter number in any non-meter reading list and obtaining a close-range meter reading starting signal;
the meter reading APP enters a water meter calibration module page and displays an environment picture, remark description information, an address and an address map of the current water meter;
when the meter reading APP obtains the operation of clicking an address map by a worker, starting a third-party navigation software, and carrying out meter reading navigation by taking the current position of the worker as a starting point and the position of a water meter as a terminal point;
and when the staff reaches the short-distance set range, the meter reading APP performs short-distance communication meter reading.
By adopting the scheme, even if the meter reading can not be realized in a long distance, the meter reading can also reach the periphery of the water meter quickly through navigation, and the meter reading in a shorter distance is realized.
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 does not exceed 1 second, solves the problem of short service life of the water meter caused by high power consumption under the condition of frequently sending signals, unifies the work pace of the water meters in one area through comprehensive coverage awakening, thereby leading all the water meters to wake up at the same time, rapidly feeding back the data of the water meters through the excitation of a meter reading machine, realizing rapid and synchronous meter reading, shortening the feedback work time of the water meters, and greatly reducing the energy consumption consumed by subsequent meter reading. Moreover, each region occupies the frequency in advance, so that the interference to other equipment is effectively avoided, and the condition of meter reading and random access is avoided. The whole meter reading system design does not need to modify the structure of the water meter and the like, and can reach the condition of a new standard, reduce the energy consumption of the water meter and prolong the working time of the water meter.
