Problems solved by technology

At this time, theoretically, it is impossible to read all the meter data within the meter reading cycle.
[0012] Therefore, in the water, electricity, heat centralized reading system, there is a problem that the effective meter reading time is tight, and all meter data cannot be read within the meter reading cycle.
[0013] To sum up, if it is necessary to meet the needs of most communities to read the water, electricity and heat data of all users within the meter reading cycle, one method is to directly reduce the single communication time (TC single ) and improve the average single communication success rate (RC single ); but this method needs to improve the performance of the underlying communication technology, requires a lot of research and experimental work, and also needs to modify the field equipment

Embodiment 1

[0036] Example 1: Combining figure 2 A method for dynamically time-sharing meter reading, which dynamically counts the communication success rate of the meter timing segment and reads the meter according to the communication success rate of the meter timing segment, wherein the calculation method for dynamically counting the communication success rate of the meter timing segment includes:

[0037](1-1) Divide a meter reading cycle into several meter reading periods; for example, the meter reading cycle is 1 day, which is divided into 24 meter reading periods on the hour;

[0038] (1-2) The communication success rate R of each meter in all periods is initially set to the initial value R int , and set the communication success weighted value W success , the communication success takes time to reduce the weight value W comm , communication failure reduction weight W fail , and the weight adjustment factor F; for example, R int 50%, W success 1%, W comm 0.01%, W fail 1% fo...

Embodiment 2

[0041] Embodiment 2: A kind of method for dynamic time-sharing meter reading meter as described in embodiment 1, in each meter reading period, according to the communication success rate of the current period of the meter, the non-reading meters are sorted, and the reading is given priority The meter with the highest communication success rate in the current period.

Embodiment 3

[0042] Embodiment 3: the method for a kind of dynamic time-sharing reading meter as described in embodiment 1, in step (1-3), described weighting algorithm of adding and subtracting is specifically: if the communication is successful, the time spent is t, then The number of times of successful communication in the current meter reading cycle S success Add 1, the communication success rate of the meter in the current period is adjusted to: R im = R im +W success –(t×W comm ), when R im >100% is fixed at 100%; if the communication fails, the number of communication failures in the current meter reading cycle S fail Add 1, the communication success rate of the meter in the current period is adjusted to: R im = R im -W fail , when R im im is 63%, if the communication is successful and the communication duration is 10 seconds, then adjust R im = R im +W success –(t×W comm )=63%+1%-(10×0.01%)=63.9%; if communication fails, adjust R im = R im -W fail = 62%.

Abstract

The invention discloses a dynamic time-sharing meter copying-reading method. When an integrated subsystem server or a concentrator is used for meter copying-reading, the dynamic time-sharing meter copying-reading method is used for solving problems that meters are too many, communication is unstable, and available meter copying reading time is short; dynamic statistic meter time-period communication success rate is promoted, and meter copying and reading are carried out based on meter time-period communication success rate. The dynamic time-sharing meter copying-reading method is capable of solving a problem that available meter copying reading time is short, and increasing integral meter copying reading success rate.

Description

technical field [0001] The invention belongs to the field of centralized copying of electricity, water, gas and heat information of residential users, in particular a reading method adopted in a sub-system or a concentrator when reading a meter for timing. Concretely, it is a method for dynamic time-sharing meter reading. Background technique [0002] In the field of centralized reading of water, electricity, heat, etc., it is necessary to use subsystems or concentrators to read data from meters such as water, electricity, heat, etc. The concentrator refers to the terminal equipment that collects the data of each collection terminal or meter, processes and stores it, and can exchange data with the master station or handheld device at the same time. The integrated subsystem server (subsystem for short) refers to the equipment that integrates the functions of the concentrator and the main station server to realize the functions of water, electricity, heat data collection, pro...
