Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
FIG. 1 schematically illustrates a flow diagram of a method for a zero cold water gas water heater in one embodiment of the invention. As shown in fig. 1, in an embodiment of the present invention, a method for a zero-cold water gas water heater including a jog cruise function is provided, which is described by taking the method as an example of being applied to a processor, and the method may include the following steps:
and step S110, acquiring water flow of a water inlet pipeline of the zero-cold-water gas water heater in a preset time period.
It can be understood that the inching cruise function is a working mode of starting combustion heating when the zero-cold-water gas water heater detects that a user regularly performs two or more than two short water switching actions at a water consumption point. The preset time period is a certain time period after the user starts to start the water switch, for example, within 5 seconds after the user starts to start the water switch. The water flow is the water flow variation of the water inlet pipeline in unit time or unit period, such as 2.5L/min.
Specifically, the processor may obtain a water flow rate of the water inlet pipeline of the zero-cold-water gas water heater within a preset time period (e.g., within 5 seconds after the user starts to start the water usage switch), for example, may establish a water flow queue buffer and a data pointer, and periodically update the water flow rate, so as to obtain the water flow rate within the preset time period, where the water flow rate may be detected by a water flow sensor installed in the water inlet pipeline of the zero-cold-water gas water heater.
And step S120, determining the water flow change rate according to the water flow.
It is understood that the water flow rate is the magnitude of the water flow change per unit time or per unit period.
Specifically, the processor determines the water flow rate change according to the acquired water flow, for example, the water flow in the current period and the water flow in the previous period may be subtracted from each other to obtain a difference value therebetween, and then the difference value is divided by the length of one period, so that the water flow rate change in the current period may be obtained.
And step S130, determining that the user triggers the inching cruise function according to the water flow change rate.
Specifically, the processor may determine that there are two consecutive actions of the user switching water according to the magnitude of the water flow rate change rate, for example, a positive-negative water flow rate change rate occurring twice in succession, so as to determine that the user has triggered the inching cruise function of the zero-cold-water gas water heater.
According to the method for the zero-cold-water gas water heater, the water flow of the water inlet pipeline of the zero-cold-water gas water heater in the preset time period is obtained, the water flow change rate is determined according to the water flow, and the inching cruise function triggered by a user is determined according to the water flow change rate. According to the method, whether the inching cruise function is triggered by the user or not is determined according to the water flow change rate, the problem that the inching cruise function is triggered by the user by mistake can be avoided, the problem that the identification accuracy rate of the inching cruise function is low is solved, and the trigger identification rate of the zero-cold-water gas water heater is improved.
In one embodiment, determining the rate of change of the water flow from the water flow comprises: determining a water flow curve according to the water flow; and (4) carrying out derivation processing on the water flow curve to obtain a water flow change rate curve.
FIG. 2 schematically illustrates a water flow rate curve and a water flow rate change curve in accordance with an embodiment of the present invention. As shown in fig. 2, the upper curve of the graph is a water flow rate curve, and the lower curve of the graph is a water flow rate change curve.
It is understood that the water flow rate profile is a profile including a plurality of continuous water flow rates within a preset time period. The water flow rate curve is obtained by performing derivation processing on the water flow curve.
Specifically, the processor may generate a corresponding water flow curve according to the water flow queue obtained within the preset time period, and obtain a first derivative of data on the water flow curve, so as to obtain a water flow change rate curve corresponding to the water flow curve.
In one embodiment, determining that the user triggered the inching cruise function based on the rate of change of water flow comprises: and determining the inching cruise function triggered by the user according to the water flow rate curve.
In particular, the processor may determine that the user triggered the jog cruise function based on the determined water flow rate profile, for example based on characteristics of the water flow rate profile.
In one embodiment, determining a user-triggered inching cruise function from a water flow rate profile includes: determining a positive wave crest and a negative wave crest of a water flow rate curve for continuous preset times; and determining the water switching action of the user for starting preset times so as to trigger the inching cruise function.
It is understood that the preset number is two or more.
Specifically, after the processor obtains the water flow rate curve, the processor analyzes the curve characteristics of the water flow rate curve, and determines that the user starts the water switching operation for the preset times when the water flow rate curve has continuous positive peaks and continuous negative peaks (refer to the water flow rate curve of fig. 2) for the preset times, that is, continuous multiple groups of positive peaks and continuous negative peaks appear on the curve, so as to trigger the inching cruise function. Referring to a water flow rate change curve below fig. 2, a derivative curve above the 0 axis indicates that water flow suddenly increases, a user opens a water faucet, and below the 0 axis indicates that water flow suddenly decreases, and the user closes the water faucet, and if the water flow suddenly decreases and is 0, the water flow is maintained, and if two continuous groups of positive peaks and negative peaks are detected, the two continuous positive peaks and negative peaks are detected, and the user continuously opens and closes the water faucet twice.
In this embodiment, when the user turns on the water switch, the water flow increases suddenly, and when the user turns off the water switch, the water flow decreases suddenly, so in this on-off process, the water flow change rate on the water flow change rate curve should be a positive number first and a negative number later, and if the user starts the switch water power operation for the preset number of times, the water flow change rate curve will have a positive peak and a negative peak for the preset number of times.
In one embodiment, the preset number of times is two.
In this embodiment, the two times are the minimum value of the preset times, and are distinguished from the normal water using action.
In one embodiment, further comprising: and filtering the water flow curve to obtain a filtered water flow curve.
FIG. 3 schematically illustrates a water flow rate profile before filtering and a water flow rate profile after filtering in accordance with an embodiment of the present invention. As shown in fig. 3, the filtered water flow rate curve is smoother than the pre-filtered water flow rate curve.
Specifically, after the water flow curve is determined, the processor may perform filtering processing on the water flow curve, filter out redundant inaccurate data, and obtain a smooth filtered water flow curve.
In one embodiment, the obtaining the water flow rate of the water inlet pipeline of the zero-cold-water gas water heater in the preset time period comprises the following steps: and under the condition that the water flow reaches a first preset water flow, acquiring the water flow of a water inlet pipeline of the zero-cold-water gas water heater within a preset time period.
FIG. 4 schematically illustrates a schematic diagram of a water flow event in accordance with an embodiment of the present invention. As shown in fig. 4, the horizontal axis represents time, the vertical axis represents water flow, and the vertical axis has two real-time thresholds, a start water flow threshold and a stop water flow threshold. The water flow is divided into 6 state events: water flow arrival, water flow departure, water flow existence, water flow constant absence, water flow temporary entry and water flow temporary exit.
1) And entering the T0 moment, indicating that the water flow is temporarily entering.
2) And the time T1 is entered, which indicates that the water flow arrives.
3) Entering the interval T1-T2 indicates that water flow exists.
4) Entering time T2, it indicates that the water flow is temporarily separated.
5) Entering time T3, indicates that water is leaving.
6) > T3 or < T0, indicating that water flow is constant.
It will be appreciated that the first predetermined water flow rate is the water flow rate at which the water flow event arrives at time T1 in fig. 4, for example 3L/min.
Specifically, when the water flow rate reaches a first preset water flow rate (e.g., 3L/min), that is, when a water flow event arrives, the processor may obtain the water flow rate of the water inlet line of the zero-cold-water gas water heater detected by the water flow rate sensor within a preset time period (e.g., 5 s).
In this embodiment, by dividing different water flow events, different water flow states can be determined more accurately according to water flow, so as to execute subsequent functional operations.
In one embodiment, determining the rate of change of the water flow from the water flow comprises: and determining the water flow change rate according to the water flow under the condition that the water flow reaches the second preset water flow.
It will be appreciated that the second predetermined water flow rate being greater than T3 or less than T0 in fig. 4 indicates a water flow rate that is constant over a water flow event, e.g., 1L/min.
Specifically, when the water flow reaches a second preset water flow (e.g., 1L/min), that is, when the water flow event is constant, the processor may determine the water flow change rate corresponding to the water flow data in the water flow queue according to the water flow queue within a preset time period (e.g., 5 s).
FIG. 5 schematically illustrates a flow diagram of a method for a zero cold water gas water heater in another embodiment of the invention. As shown in fig. 5, in an embodiment of the present invention, a method for a zero-cold water gas water heater including a jog cruise function is provided, which is described by taking the method as an example applied to a processor, and the method may include the following steps:
step S510, acquiring the water flow of a water inlet pipeline of the zero-cold-water gas water heater in a preset time period under the condition that the water flow reaches a first preset water flow.
And step S520, determining a water flow curve according to the water flow under the condition that the water flow reaches a second preset water flow.
Step S530, filtering the water flow curve to obtain a filtered water flow curve.
And step S540, performing derivation processing on the filtered water flow curve to obtain a water flow change rate curve.
And step S550, determining that the inching cruising function is triggered by the user according to the water flow rate change curve.
Specifically, when the processor determines that the water flow rate change curve has continuous positive peaks and continuous negative peaks for preset times, the processor determines that the user starts water switching actions for the preset times to trigger the inching cruise function.
In the embodiment, the water flow is obtained in the preset time period after the water flow event arrives (that is, the water flow reaches the first preset water flow), the water flow curve is generated according to the water flow under the condition that the water flow event is constant (that is, the water flow reaches the second preset water flow), the filtering processing is performed on the water flow curve, the noisy data are removed, the first-order derivation processing is performed on the filtered water flow curve to obtain the water flow change rate curve, whether the on-off water actions of the preset times in the preset time period exist or not is determined according to the characteristics of the water flow change rate curve, and therefore the fact that the user triggers the inching cruise function of the zero-cold-water gas water heater is determined. According to the method, whether the inching cruise function is triggered by the user or not is determined according to the water flow change rate, the problem that the inching cruise function is triggered by the user by mistake can be avoided, the problem that the identification accuracy rate of the inching cruise function is low is solved, and the trigger identification rate of the zero-cold-water gas water heater is improved.
FIG. 6 schematically illustrates a flow diagram of a method for a zero cold water gas water heater in another embodiment of the invention. In an embodiment of the present invention, as shown in fig. 6, a method for a zero-cold water gas water heater including a jog cruise function is provided, which is exemplified by applying the method to a processor.
Specifically, the processor judges whether a water flow event arrives according to the water flow, if not, the processor enters an ending step, if so, water flow signal (namely the water flow) queue acquisition is carried out, timing is started, whether the timing time reaches 5 seconds is judged, if not, the water flow signal queue acquisition is continued, if yes, whether the water flow event is constant or not is judged according to the water flow, if not, the ending step is carried out, if not, the water flow historical queue smoothing filtering processing step is carried out, first-order derivation is carried out on the water flow queue, the derivative characteristic is judged, whether 2 continuous positive and negative actions are detected or not is judged, if not, the ending step is carried out, if the detected action is determined to exist 2 times of switch water actions within 5 seconds, and at the moment, the inching cruising function mode of the zero-cold water gas water heater is started.
In the embodiment, the technical scheme adopts a software mode, whether the inching cruise function is triggered by a user is determined according to the water flow change rate, the problem that the inching cruise function is triggered by the user by mistake can be solved by accurately deducing whether 2 times of water switching actions of the user exist by using a queue control principle, a smooth filtering algorithm and a mathematical derivative function through a water flow sensor, the problem that the inching cruise function is triggered by the user by mistake is solved, the problem that the identification accuracy rate of the inching cruise function is not high is solved, the trigger identification rate of the zero-cold-water gas water heater is improved, the convenience of starting the zero-cold-water function is improved, and the use experience of the user is enhanced.

Referring to the water flow rate curve below fig. 2, the derivative curve shows that the water flow suddenly increases above the 0 axis, the user opens the faucet, and shows that the water flow suddenly decreases below the 0 axis, the user closes the faucet, and if 0 is detected, the water flow is maintained, and if two consecutive positive and negative peaks are detected, the positive and negative peaks are detected, and the user continuously opens and closes the faucet twice.
In this embodiment, when the user turns on the water switch, the water flow increases suddenly, and when the user turns off the water switch, the water flow decreases suddenly, so in this on-off process, the water flow change rate on the water flow change rate curve should be a positive number first and a negative number later, and if the user starts the switch water power operation for the preset number of times, the water flow change rate curve will have a positive peak and a negative peak for the preset number of times.
In one embodiment, the preset number of times is two.
In this embodiment, the two times are the minimum value of the preset times, and are distinguished from the normal water using action.
