In this embodiment, the electric energy analysis first needs to analyze the electric energy metering error, as shown in fig. 2, the user enters the house and configures the main intelligent switch K Z An intelligent switch K is respectively arranged on each power utilization branch 1 ～K 5 The intelligent switch can acquire information such as voltage, current, power, electricity utilization and the like of each branch in real time; assuming that the electric quantity measured by the electric energy meter in a specified time period is W 0 The electric quantity measured by the intelligent household-entering switch is K Z And the error between the two is gamma, then:
when gamma is less than or equal to gamma set When the electric energy metering error is qualified, the gamma is judged to be qualified set In practice, because the uncertainty of the power consumption of the user and the unstable state of the intelligent switch power metering are large in power metering error fluctuation, whether gamma is qualified at a certain time cannot be directly used as a standard for judging the qualified power metering error, and in the embodiment, the maximum gamma in the probability of 90% of the measured error is specified to be obtained 90 As a basis for judging whether the electric energy metering error is qualified or not, the probability value gamma 90 of the error 90% can be as followsMethod approximate selection: sorting the errors from large to small, discarding the large value of the first 10%, and taking the maximum value of the residual errors. In summary, when γ 90 ≤γ set And if not, judging that the metering is not accurate, and contacting a power department for verification.
In the embodiment, for the analysis of the saving of the electric energy, the analysis is carried out according to the electricity price of the resident electricity step, and the electricity consumption is less than W in a natural year jt1 Executing the first step of electricity price, the electricity consumption is more than W jt1 And is smaller than W jt2 Executing a second step price, and the power consumption is more than W jt2 And executing third step electricity price. As a general user, it is most economical to keep the electricity price at the first step.
The intelligent energy system calculates the daily planned power consumption W according to the first-step power consumption d,n If the actual power consumption W of the current day s,n Excess of planned power consumption W d,n In time, the intelligent energy system can send out a power saving prompt and prompt the exceeding power consumption W c,n ，
When the smart energy system is used for the first time, because the electricity consumption big data is lacked, the planned electricity consumption on the 1 st day is as follows:
the planned electricity consumption on the nth day was:
n is an integer greater than 1, n is 365 s,n The actual power consumption on the ith day is calculated according to the following formula:
W c,n ＝W d,n -W s,n 。
in the embodiment, the analysis of the electricity safety comprises the analysis of whether a single electric appliance is operated or not, and for high-power electric appliances, the rated power P is input in the comprehensive energy system e The system can automatically calculate the rated current value according to a formula
In the formula of U e,c Measured voltage value, I, for intelligent air switch e,c Calculating a current value for the integrated energy system; then other electrical equipment of the branch circuit is closed, and under the condition that only the electrical equipment is switched on, the actually measured current of the intelligent switch is I c When I is e,c >K Ie,c If K is a number greater than 1 and can be set to 1.05, the electric appliance is judged to be in electric leakage or overload operation, and if not, the electric appliance is judged to be in normal operation. The method also comprises the steps of monitoring the whole indoor electrical system in real time, checking whether electrical equipment is in leakage or overload operation one by one according to the safe operation analysis method of the individual electrical equipment, ensuring that the electrical equipment is in a normal state, and respectively turning on the intelligent air switches K as shown in figure 2 1 、K 2 Make all branch road electrical equipment and illumination, and record intelligent air switch K 1 、K 2 ，....，K n Measured current value of (I) k1 、I k2 ，...，I kn Current value of I k1 、I k2 ...I kn And inputting the energy into an integrated energy system. The comprehensive energy system monitors that the current of the ith branch is I in real time i When I is i ＞k set ×I ki When the branch circuit is in a leakage state, an alarm is sent out, and the branch circuit is judged to be in a leakage state, k set Can be set according to practical conditions, and is recommended to be 1.05 when I is i ≤I ki And judging that the branch is normal.
In this embodiment, including water resource saving analysis method and water safety analysis method to water resource analysis, when carrying out water resource saving analysis, the intelligent water gauge of installation passes through the network, with data transfer to wisdom energy system, wisdom energy system can the real-time supervision water consumption condition, through computational analysis, can monitor whether the water pipe has the condition of leaking, the water use condition of assay every day to give the water conservation suggestion. In the region where the stepped water price is implemented, the water consumption is less than m in a natural month 1 Performing a first step of water price, wherein the water consumption is more than m 1 And is less than m 2 Performing a second step of water priceWater quantity is more than m 2 And executing third step water price. It is obvious that controlling the water consumption in the first step is the most economical and the most water saving. The intelligent energy system in the demand side comprehensive energy system calculates the daily planned water consumption m according to the first-step water consumption d,n If the actual water consumption m of the day s,n Water consumption m beyond plan d,n In time, the intelligent energy system can give out a water-saving prompt and prompt the excessive water consumption m c,n 。
When using wisdom energy system for the first time, because lack the big data of water use, so the planned water consumption of day 1 is:
the planned water usage on day n,
n is an integer greater than 1, and n is equal to or less than 30. mm is s,i The actual water consumption on the ith day is calculated according to the following formula: m is c,n ＝m d,n -m s,n 。
In this embodiment, the water resource analysis further includes an analysis of water safety, and the analysis flow is as shown in fig. 3, according to the water usage law of the user: the water is used intermittently, namely, the water is continuously used for a certain time, and is used after being closed, according to the rule, in the time interval from t1 to t2, a user can set the time (recommended setting is 10 min) according to the actual longest continuous water use time, the reading of the water meter continuously moves, and under the condition of no stop, the water pipe can be judged to be water leakage or water dripping, in the time interval from t1 to t2, when the water meter stops moving, the timing is stopped, when the water meter moves again, the timing is restarted, and when the water flow is larger than the set maximum value, the water pipe is considered to be broken, and the main valve is prompted to be checked and closed.
In the embodiment, the use analysis of the natural gas comprises a natural gas saving analysis method, the natural gas is not subjected to step price in China at present, and in order to save the gas, the planned gas consumption q per month can be set j,h When the daily gas consumption exceeds the scheduleWhen the value is in value, a gas saving signal is sent; when the intelligent energy system is used for the first time, due to the lack of gas utilization data, the planned gas utilization amount on the 1 st day is as follows:
the planned gas usage on the n-th day,
n is an integer greater than 1, and n is equal to or less than 30. q. q.s s,i Actual gas usage on day i.
Exceeding gas consumption q c,n Calculated according to the following formula:
q c,n ＝q d,n -q s,n 。
the analysis on the use of the natural gas also comprises analysis on the use safety of the natural gas, and the analysis flow is shown in fig. 4. Users generally use natural gas through gas water heaters and natural gas stoves, and do not install gas leakage monitors at home. Generally, when cooking, the continuous use time of gas is the longest, and the use rule of a gas water heater is that the gas water heater is used for a plurality of times in a short time within a time period. According to the rule, in the time interval from t1 to t2, the user can set the gas time according to the longest continuous use (recommended setting is 20 min), the reading of the gas meter continuously moves, and the gas leakage can be judged under the condition that the gas meter is not stopped. If the air-using state is in the air-using state, the reset key can be pressed. And in the time interval from t1 to t2, when the gas meter stops moving, the timing is terminated, and when the gas meter moves again, the timing is restarted.
When water heating analysis is performed, in the embodiment, the structure diagram of the water heating system is shown in fig. 5, most areas in China currently adopt central heating, most areas collect the cost of one heating season at a time according to the building area, so that the heating time and temperature cannot be controlled, and meanwhile, due to the adoption of hot water circulation heating, when a heating pipeline is blocked or water leaks, a user cannot find the time in time.In order to solve the problems, the demand side comprehensive energy system, the energy-saving and safety analysis method and the energy-saving and safety analysis method can optimally save heating cost under the condition of ensuring comfortable indoor temperature, and can also monitor whether a heating pipeline is blocked or leaks in real time. As shown in FIG. 5, the intelligent heating meter collects the water flow Q of the water inlet pipe in real time input Flow rate of each branch Q input1 、 Q input2 、Q input3 、...、Q inputn Water flow Q of water outlet pipe output Temperature T of water inlet pipe input Temperature T of water outlet pipe output . And the intelligent heating meter transmits the acquired data to the comprehensive energy system. When the heating pipeline leaks and judges, because the cross-sectional area of inlet tube and outlet pipe is usually the same big, so theoretically the flow of inlet tube and outlet pipe should equal, promptly:
Q input ＝Q output
the cross-sectional area of each branch pipe of the inlet pipe is usually equally large, so in theory the flow of each branch pipe should be equal, i.e.:
Q input1 ＝Q input2 ＝Q input3 ＝...＝Q inputn
when the water pipe of the heating installation leaks, the water flow of the water inlet pipe is larger than that of the water outlet pipe, namely Q input -Q output ＞Q ls1 In the meantime, the water leakage of the heating pipe can be considered, Q ls1 Is a positive number, Q ls1 The larger the size, the more serious the water leakage. In the branch pipe, the pipe with the maximum flow and the pipe with the minimum flow are selected, and the flow of the pipe m is supposed to be Q at the maximum max.m The minimum flow of the pipeline n is Q min.n When the maximum and minimum difference is greater than Q ls2 If so, the water leakage of the pipeline m is judged. When the two conditions are met simultaneously, the comprehensive energy system sends a water leakage alarm signal of the heating pipeline and prompts the pipeline m to leak water.
Carry out heating pipe and block up the judgement, when certain branch heating pipe blocked up, the discharge of inlet tube still equaled outlet pipe discharge, works as | Q input -Q output |＜Q ds1 When the current is in the normal state; at the same time, inIn the branch pipes, the pipe with the maximum flow and the pipe with the minimum flow are screened, and the maximum flow of the pipe i is assumed to be Q max.i The minimum flow of the pipeline j is Q min.j When the maximum and minimum difference is greater than Q ds2 If so, it is determined that the pipe j is clogged. When the two conditions are met simultaneously, the comprehensive energy system sends out a warning signal for the blockage of the heating pipeline and prompts the blockage of the pipeline j.
On the premise of no blockage and no water leakage of a heating pipeline: the water flow of the water inlet pipe is more than Q, the actually measured water temperature of the water inlet pipe is more than T1, and the actually measured water temperature of the water outlet pipe is more than T2, the water inlet pipe is in a normal heating state, otherwise, the water inlet pipe is in an abnormal heating state, and the water inlet pipe can be connected with a heating company for processing; when the indoor temperature is lower than the set temperature value, the heating valve can be increased or the indoor window can be closed. When the indoor temperature is higher than the set temperature value, the heating valve can be closed, the flow of the heating air is reduced, and meanwhile, the indoor temperature can be reduced, so that the heating resource is saved.
The invention provides a demand side comprehensive energy system, energy-saving and safety analysis and a method, which respectively monitor the electricity, gas, water and heat energy consumption of a user in real time through an intelligent energy system, an intelligent electric energy meter, an intelligent natural gas meter, an intelligent water meter and an intelligent energy meter in the comprehensive energy system, judge the use amount of the user in the aspects of electricity, water, gas and heating installation and whether potential safety hazards exist or not through calculation and analysis of the use of each energy, send energy-saving and safety reminding signals when the use amount exceeds the standard and the potential safety hazards exist, save resources to the maximum extent for the user, achieve the optimal energy-saving effect, and assist China to realize 'carbon peak reaching and carbon neutralization'.
