The pulse flowmeter is an instrument for measuring the flow of fluid in a pipeline or an open channel by pulse counting, and the working principle of the pulse flowmeter is as follows: when fluid flows through the sensor shell, the blades of the impeller have certain angles with the flow direction, and the impulsive force of the fluid enables the blades to have rotating torque, so that the blades rotate after overcoming the friction torque and the fluid resistance, and the rotating speed is stabilized after the torque is balanced. Under certain conditions, the rotating speed is in direct proportion to the flow speed, and the blades have magnetic conductivity and are positioned in a magnetic field of a signal detector (consisting of permanent magnetic steel and a coil), so that the rotating blades cut magnetic lines of force, the magnetic flux of the coil is periodically changed, and electric pulse signals are induced at two ends of the coil.

The following describes a method for calibrating a flow meter disclosed in an embodiment of the present application.
As shown in fig. 4, fig. 4 is a schematic flowchart of a method for calibrating a flow meter according to an embodiment of the present application. Based on the electronic apparatus shown in fig. 2, the following steps S400 to S450 are implemented when the processor 22 executes the program stored in the memory 21.
Step S400: the pulse equivalent of the flow meter is obtained.
In the embodiment of the present application, the pulse equivalent represents the relation between the number of pulses output from the flow meter and the oil filling flow rate detected by the flow meter. The pulse equivalent is calibrated in advance when the flowmeter leaves a factory, and then the flowmeter is calibrated by the calibration method in the steps S400 to S450, so that the pulse equivalent can be continuously updated, and the latest calibrated pulse equivalent is stored, which is convenient for being directly called when the flowmeter is calibrated next time.
Step S410: and acquiring a specified first oiling flow.
In the embodiment of the application, the first oiling flow rate can be specified and adjusted by people. In an optional implementation manner, a monitoring interface may be generated on the electronic device, so that the composition structure and corresponding state information of the oiling system are displayed on the monitoring interface. Referring to fig. 5, fig. 5 is a schematic diagram of a monitoring interface applied in the embodiment of the present application. As shown in fig. 5, a status bar 50 corresponding to each flow meter is generated in the monitoring interface, and the status bar 50 includes a clear control 501, a first information frame 502, a second information frame 503, and a third information frame 504. The first information box 502 is used for displaying the first oil injection flow rate of the corresponding flow meter, and based on this, the electronic device may further obtain the first oil injection flow rate which is manually input through the first information box 502. The second information box 503 and the third information box 504 are used to display the current flow rate and the current flow velocity of the corresponding flow meter, respectively. And when a confirmation operation (such as a click operation) on the clear control 501 is detected, performing clear processing on the corresponding flow meter.
In addition, the monitoring interface is also used for graphically displaying various components and connection relations of the oil filling system shown in fig. 3, for example, an icon 51 represents a flow meter, an icon 52 represents equipment to be filled, an icon 53 represents an oil storage tank, an icon 54 represents a vacuum gauge, detection information 541 of the vacuum gauge is displayed at the icon 54, an icon 55 represents an evacuation pipeline, an icon 56 represents a condenser, an icon 57 represents a roots pump, and an icon 58 represents a vacuum pump, so that the visualization degree of oil filling monitoring is optimized.
Step S420: and calculating the target pulse number corresponding to the flowmeter according to the pulse equivalent and the first oil injection flow.
In an alternative embodiment, the target number of pulses is equal to the pulse equivalent × the first injection flow rate. In another embodiment, the proportionality coefficient for calculating the target pulse number may be adjusted according to actual demand, for example, where k is the proportionality coefficient, k is k × pulse equivalent × first oil injection flow rate.
Step S430: and controlling the oil injection device to inject oil into the equipment to be injected according to the target pulse number.
Specifically, the electronic device can control the oil injection device to open the oil delivery valve, so that the oil delivery pipeline is conducted, the oil injection device injects oil into the equipment to be injected, and the flow meter generates pulses to start pulse counting. When the accumulated pulse number acquired by the electronic equipment through the flowmeter reaches the target pulse number, the electronic equipment controls the oil injection device to close the oil delivery valve, so that the oil delivery channel is disconnected, oil injection is finished, and the primary oil injection process is completed.
Step S440: and acquiring calibration configuration information, and determining the configuration state of the flowmeter according to the calibration configuration information.
In some alternative embodiments, before step S440, the electronic device may generate a calibration configuration interface, and generate a configuration region corresponding to the flow meter in the calibration configuration interface, where the configuration region includes the selection control and the input region. Correspondingly, step S440 specifically includes: the electronic device detects operational information for the selection control and determines a configuration state of the flow meter based on the operational information. And acquiring the actual oil injection amount inside the equipment to be injected through the input area. The electronic device determines calibration configuration information based on the configuration status and the actual fill level.
Referring to fig. 6, fig. 6 is a schematic diagram of a calibration configuration interface according to an embodiment of the present application. As shown in fig. 6, the electronics display the configuration area of each flow meter in the calibration configuration interface, i.e., the row area in table 60. The configuration area includes selection controls (i.e., calibration selection boxes), an input area for detecting manually entered information, such as actual fill volume, and a display area for entering information that does not require configuration, such as the flow meter's numbered information "calibration selection 921" or the like. When the user needs to calibrate the flow meter with the serial number information of the calibration selection 921, the calibration selection frame corresponding to the flow meter can be selected, and then the electronic device determines that the configuration state of the flow meter is the calibration state. Conversely, when the user does not check the calibration selection box corresponding to a certain flow meter, for example, the flow meter with the number information of "calibration selection 922", the electronic device determines that the configuration state of the flow meter is not the calibration state.
In another alternative embodiment, the electronic device may also directly obtain weighing information of the device to be filled with oil through a weighing device, and calculate an actual amount of oil filled in the device to be filled according to a formula v-m/ρ, where v represents the actual amount of oil filled, m represents the weighing information, and ρ represents the medium density of the oil.
Step S450: and if the configuration state is the calibration state, acquiring the actual oil injection amount inside the equipment to be injected, and calibrating the pulse equivalent according to the target pulse number and the actual oil injection amount to obtain new pulse equivalent.
In an alternative embodiment, in step S450, if the configuration status is the calibration status, the electronic device may further calculate a flow deviation value according to the actual oil injection amount and the first oil injection flow rate. If the flow deviation value does not satisfy the preset calibration condition, calculating a new pulse equivalent according to the target pulse number and the actual oil injection amount, and continuing to execute the step S410. The preset calibration condition may be set and adjusted manually, for example, the preset calibration condition is that the flow deviation value does not exceed 0.1L, which is not limited specifically. Therefore, the electronic equipment can calibrate the flowmeter for multiple times until the latest flow deviation value does not meet the preset calibration condition, and the accuracy of flowmeter calibration can be optimized.
In some optional embodiments, in order to observe the actual oil injection condition more accurately, the electronic device may further acquire a designated acquisition period, and sequentially acquire the first pulse number and the second pulse number output by the flow meter according to the acquisition period during the process of controlling the oil injection device to inject oil into the device to be injected with oil. And then, the electronic equipment subtracts the second pulse number from the first pulse data to obtain a periodic pulse number, so that the flow rate information of the flowmeter is calculated according to the periodic pulse number and the pulse equivalent, and the oiling speed monitoring during the acquisition period is realized. Optionally, referring to fig. 5, the electronic device may determine, in the monitoring interface, that the third information box 504 corresponding to the flow meter displays the flow rate information.
Further, in an implementation manner, the electronic device may specifically calculate, according to a preset flow rate calculation formula, the flow rate information of the flow meter by combining the number of periodic pulses and the pulse equivalent. Wherein, the flow velocity formula is: flow rate information is (number of periodic pulses divided by pulse equivalent) × (preset duration divided by collection period). The preset time duration is related to a unit of the flow rate information, for example, if the flow unit is liter/minute, the preset time duration is 60 seconds, and if the flow unit is liter/hour, the preset time duration is 3600 seconds.
In some alternative embodiments, after step S450, the electronics can also add one to the running total of the number of calibrations for the flow meter to update the calibration count. Based on this, for each calibration, in step S410, the electronic device may first obtain the calibration time of the flow meter, and in a case that the calibration time of the flow meter is the first time, take the preset oil injection flow rate as the specified first oil injection flow rate. The preset oil injection flow rate is manually specified and adjusted, for example, the preset oil injection flow rate is 10 liters or 12 liters, which is not particularly limited.
And under the condition that the calibration times are not the first time, the electronic equipment acquires the historical oiling flow rate appointed in the last calibration, and calculates the appointed first oiling flow rate according to the historical oiling flow rate. It can be understood that the calculated relationship between the historical oiling flow rate and the first oiling flow rate can be adjusted according to actual needs.
For example, in one implementation, the first oil injection flow rate is equal to the historical oil injection flow rate + (the number of times of calibration-1) × the preset oil injection flow rate, for example, if the preset oil injection flow rate is 10 liters, the first oil injection flow rate specified in the second calibration is 20 liters. In another mode, the flow deviation value calculated in the last calibration may be obtained as a history deviation value, and the history deviation value is converted into a matching weighted weight, so that the first oil injection flow is the history oil injection flow + the weighted weight × the preset oil injection flow, where the history deviation value and the weighted weight may satisfy a positive correlation conversion relationship, and no limitation is made. Therefore, according to the deviation degree of the last calibration, the oiling flow can be adaptively adjusted, the calibration requirement is met, and the calibration efficiency is favorably improved.
In the case of adding the calibration count, further, in some optional embodiments, step S430 may specifically be: and under the condition that the calibration times are the first time, the electronic equipment initializes the flowmeter, and controls the vacuumizing device to vacuumize the equipment to be filled until the vacuum degree in the equipment to be filled meets the preset vacuum degree. The initialization process includes, but is not limited to, a process of clearing the number of pulses of the flow meter. And then, the electronic equipment controls the oil injection device to inject oil into the equipment to be injected, and detects the accumulated pulse number output by the flowmeter in the oil injection process. And when the accumulated pulse number reaches the target pulse number, controlling the oil injection device to stop oil injection so as to realize oil injection control.
In practical application, as shown in fig. 6, the electronic device may further generate a first configuration area 61 and a second configuration area 62 in the calibration configuration interface, detect an acquisition cycle input by the user through the first configuration area 61, and detect a preset vacuum degree input by the user through the second configuration area 62, so that the operation is convenient.
Therefore, by implementing the method embodiment, the pulse equivalent is taken as a variable for representing the ratio relation between the pulse number output by the flowmeter and the detected oiling flow, so that the method can respond to the actual requirement of a user, flexibly calibrate the pulse equivalent of the flowmeter when measuring different medium flows, is beneficial to widening the application scene of the flowmeter, and simultaneously improves the measurement accuracy so that the oiling device stably operates.
