Embodiment
The assay method and system of service factor while the present invention provides a kind of gas equipment, to make the mesh of the present invention
, technical scheme and effect it is clearer, clear and definite, the present invention is described in more detail below.It is it should be appreciated that described herein
Specific embodiment only to explain the present invention, be not intended to limit the present invention.
Referring to Fig. 1, the assay method preferred embodiment of service factor while Fig. 1 is a kind of gas equipment of the invention
Flow chart, as illustrated, it includes step：
S1, determine industrial and commercial customer flow table to be measured；
S2, the maximum gas consumption day chosen in meter reading metering period are sample time, choose the maximum hour flow of this day
As calculating flow；
S3, statistics and the metered flow for recording gas equipment；
S4, according to the following formula gas equipment while service factor：
In formula：QhFor the calculating flow of industrial and commercial user；K0For gas equipment while service factor；QxFor gas equipment
Metered flow；N is the quantity of gas equipment.
The industrial and commercial customer flow table is food and drink user, enterprises and institutions user, hotel user, school user, public place of entertainment
The flowmeter of institute user.
The industrial and commercial customer flow table includes target formula table, ultrasonic flowmeter, epithelium table or waist wheel table.
Coincidence factor K0Reflect the degree that is concentrated use in of gas equipment, K0Value is bigger, and gas equipment is concentrated use in
Degree is higher, and it is closely related with the management state of user, the quantity of gas appliance and species.
Service factor while industrial and commercial user, it can calculate as follows.
(1) methods of sampling and sample size
Because industrial and commercial number of users is huge, it is difficult to which all users are analyzed with gas record.Sample investigation can be taken
Method, a number of sample is chosen, calculate coincidence factor.The method that the present invention takes simple random sampling, takes out at random
Taking n unit, n takes 30 in this investigation as sample.
The commercial user of the influence, as far as possible cover all kinds of user type, including food and drink, wine are considered during sampling simultaneously
Shop, school, dining room etc..
(2) selection of actual maximum stream flow
The maximum gas consumption day chosen in meter reading metering period is sample time, chooses the maximum hour flow conduct of this day
With reference to calculating flow.
