EXAMPLE III
The method for automatically detecting the characteristics of the fire pump provided by the third embodiment is applied to the system as claimed in claim 4, and as shown in fig. 3, the method comprises the following steps:
and S1, obtaining the rated flow of the water pump to be detected. It should be noted that the rated flow rate of the water pump to be detected is generally marked on the nameplate.
S2, acquiring opening gradient information of the electric valve according to the rated flow; wherein, the opening gradient information comprises a group of opening signals. One possible opening gradient information includes: 10%, 30%, 50%, 70%, 80% and 95%. Wherein 10%, 30%, 50%, 70%, 80% and 95% refer to opening values of the electrically operated valve. It should be noted that the opening degree signal of the opening degree step information is related to the specific parameter of the electric valve used.
S3, sequentially sending opening degree signals to the electric valves according to the opening degree gradient information; and each opening signal is used for indicating the electric valve to adjust to a corresponding preset opening. That is, the controller sends a signal to the electrically operated valve to adjust the valve opening thereof. As described in S2, the opening degree of the electrically operated valve is adjusted to 10%, 30%, 50%, 70%, 80% and 95%, respectively, correspondingly.
And S4, receiving a plurality of flow value signals sent by the flow sensor in each preset opening state and a plurality of pressure value signals sent by the pressure sensor in each preset opening state. In this step, the controller will receive the flow value signal and the pressure value signal from the flow sensor and the pressure sensor, respectively. The flow rate value signal and the pressure value signal are plural and correspond to the opening degree of the electric valve one by one.
And S5, generating a graph according to the flow value signals and the pressure value signals. In other words, a graph that can be directly displayed by a terminal or other display device is generated based on the flow value signal and the pressure value signal.
By adopting the method to measure the characteristic parameters of the water-proof pump, the participation degree of manual measurement can be effectively reduced, and the detection efficiency and the measurement accuracy are improved; meanwhile, due to the fact that the graph is formed, a user can conveniently analyze the detection result according to the graph, and predict and adjust the detection process according to the graph, and therefore the possibility of prediction of the detection process is achieved.
Alternatively, as shown in fig. 4, step S4 includes:
s401, obtaining a stable time threshold value and a stable amplitude threshold value.
Wherein the stability time threshold is used to indicate a time span of the pressure detection, and the stability amplitude threshold is used to indicate a maximum variation amplitude of the pressure value. Further, the settling time threshold is a short observation period set for the accuracy of the measurement result. If the detected items (such as flow and pressure) are kept relatively stable (i.e. pressure is taken as reference, if the pressure fluctuation is not large and is expected), the observation process is taken as the detection process to obtain the relevant data.
S402, obtaining a first test flow value and a first test pressure value of a first preset time point under the opening degree, and a second test flow value and a second test pressure value measured between the first preset time point and a second preset time point; and the time interval between the first preset time point and the second preset time point is a stable time threshold. In the process, firstly, first measurement is carried out at a first preset time point to obtain first data (namely a first measured flow value and a first measured pressure value); and then randomly carrying out a second measurement (namely, a second measured flow value and a second measured pressure value) within a time which is not more than a stability time threshold value after the first preset time point, and averaging the two measurement results to be used as a target value if a certain reference is in accordance with the expectation (such as that the pressure fluctuation is not large) according to the two measurement results.
S403, if the absolute value of the difference between the first test pressure value and the second test pressure value is smaller than the stable amplitude threshold value, taking the average value of the first test flow value and the second test flow value as the flow value.
The average of the first test pressure value and the second measured pressure value is taken as the pressure value. As mentioned above, the purpose of this step is to use the mean value as the target value (the value of the corresponding term to be obtained).
Steps S402 and S403 are described by way of example. At present, characteristic detection is carried out on a certain fire pump, the threshold value of the stable time is 2 seconds, and the threshold value of the stable amplitude is 500Pa. At a certain opening k, at T1The first test flow value measured at the time point is Q1The first measured pressure value is P1(ii) a At T2A certain time T before the point in timexThe second measured flow value is measured as Q2The first measured flow value is P2And | P2-P1|≤500Pa. Wherein, T2＝T1Time point of +2 (S). Then, the flow rate Q of the fire pump at the opening degreekPressure value PkRespectively as follows:
and S404, respectively generating a flow value signal and a pressure value signal according to the flow value and the pressure value. The step is to convert the flow value and the pressure value respectively and generate corresponding signals so as to facilitate transmission.
According to the method, the measured value at any time point is adopted, the stable value is extracted at random at the later moment, and the average value of the measured value and the stable value is taken as the target value.
Alternatively, the graph regarding the flow rate value and the pressure value generated in step S5 is a two-dimensional line graph in which the flow rate value is the Y axis and the pressure value is the X axis. Fig. 5 is a schematic diagram showing a two-dimensional line chart of the automatic detection method for the characteristics of the neutral water pump in the third embodiment of the present invention.
This figure adopts two-dimensional line graph, is favorable to the user to observe the testing result on the one hand, and on the other hand is favorable to the user to judge the exactness of testing process accurately, and for other figures, this two-dimensional line graph more is favorable to the user to carry out the judgement whether this fire water pump's characteristic accords with relevant standard.
