Technical Field

The invention relates to the technical field of fluid metering, in particular to a fluid charging method for charging according to time.

Background

In the process of fluid metering, the charging is generally carried out according to time or flow rate according to the fixed flow rate of the fluid in the pipeline. For example, showers in schools or businesses, generally use a meter that can be swiped with an IC card, but the pressure of hot water may be reduced due to the diversion of multiple hot water pipes during peak water usage periods.

If the time-based billing method is used, the fluid pressure is reduced, so that the fluid flowing out in the same time is reduced, but the billing time is not changed, so that the user pays more expense, and the user experience is poor.

For the problem, the charging device charging according to time is directly replaced by the charging device charging according to flow under the general condition, the original charging device is not effectively utilized, and the waste of funds and resources is caused.

Disclosure of Invention

The embodiment of the invention provides a fluid charging method for charging according to time, which can solve the problems in the prior art.

The invention provides a fluid charging method based on time charging, which comprises the following steps:

detecting the real-time pressure of fluid in the pipeline;

comparing the real-time pressure with a standard pressure;

if the real-time pressure is less than the standard pressure but greater than the fault pressure, the real-time pressure is substituted into the billing time calculation formula t-0.000013P³+0.003456*P²-0.3256P +14.14 calculates the unit billing time per unit price required in case of a fault, where P represents the pressure, t is the unit billing time, and after determining the unit billing time, the total charge is calculated from the counted total time.

The fluid charging method based on time charging only needs to be modified on the basis of the original time charging device, and the modification cost is low. Even if pressure is reduced due to the fact that a plurality of pipelines are shunted in a peak period, when the charging device is used, charging time can change along with the pressure, the charging time is longer when the pressure is lower, the total flow which costs the same cost is unchanged, a charging result cannot exceed normal cost, a user normally expends the cost, and user experience is good.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention provides a fluid fee counter for charging according to time, which comprises a pressure sensor and a fee counter, wherein the pressure sensor is arranged on the inner wall of a pipeline close to an outlet and used for collecting the real-time pressure of fluid in the pipeline, and the fee counter calculates the fee according to the real-time pressure.

After receiving the real-time pressure data sent by the pressure sensor, the charging device compares the real-time pressure with the standard pressure to judge whether the pressure in the pipeline is normal or not. If the real-time pressure is greater than or equal to the standard pressure, the fee counter calculates the fee according to the standard fee price. For example 1 point every 3 s.

If the real-time pressure is less than the standard pressure but greater than the fault pressure, the meter substitutes the real-time pressure into a meter time calculation formula t-0.000013P³+0.003456*P²-0.3256P +14.14 calculates the required billing time per unit price in case of failure, where P represents the pressure and the unit KPa, t is the billing time per unit, s. And after the unit charging time is determined, the charger calculates the total charge according to the counted total time. In this embodiment, the charging time is calculatedThe formula is obtained by fitting data obtained by experiments, a curve corresponding to the formula is shown in figure 1, a pipeline used in the experiments is a DN20 steel pipe, and the inner diameter is 21 mm.

If the real-time pressure is less than or equal to the fault pressure, the meter stops the charging.

Based on the fluid fee counter, the invention also provides a fluid fee counting method based on time, which comprises the following steps:

detecting the real-time pressure of fluid in the pipeline;

comparing the real-time pressure with the standard pressure, and if the real-time pressure is greater than or equal to the standard pressure, calculating the cost according to the standard charging price;

if the real-time pressure is less than or equal to the fault pressure, the billing is stopped.
