Description

NON-MAGNETIC METERING TESTING DEVICE AND METHOD

TECHNICAL FIELD

MOM] The present disclosure relates to the technical field of water meter detection, and specifically relates to a non-magnetic metering testing device and method.

BACKGROUND ART

[0002] The intelligent water meter partially replaces a traditional mechanical water meter, and the metering modes, such as mechanical meter head detection, ultrasonic detection and magnetic detection, of the intelligent water meter are more and more diversified along with the development of the electronic technology. However, the metering modes have obvious defects and are prone to external electromagnetic interference. Or, metering errors are caused by accumulated adsorption of the permanent magnet to impurities in water. Or, the metering modes are manually utilized, missed and ignored. In order to solve the problems, a non-magnetic metering water meter is produced and has the advantages of high metering precision, no magnetism, no impurity adsorption, no artificial interference and the like. The non-magnetic water meter is formed by adding a lifting semicircular metal pointer on the basis of a traditional mechanical water meter. When water flows through the water meter, the semicircular metal pointer is driven to rotate, and the rotation of the metal pointer causes electromotive force influence on the non-magnetic sensor, so that non-magnetic metering data acquisition and reading are realized. Therefore, die optimal detection distance between the non-magnetic sensor and the semicircular metal pointer is a key factor influencing the accuracy of non-magnetic metering, and detection distance verification and conversion counting comparison are needed in the design and production process of the non-magnetic sensor to verify the accuracy of magnetic metering.

[0003] When the non-magnetic water meter is produced in batch, whether the product is qualified or not can be tested and identified only after the electronic modules and the mechanical parts of the whole non-magnetic water meter are completely assembled. Once the phenomenon of inaccurate water metering exists, the reason of die mechanical parts or the electronic module parts is difficult to determine. Usually, the whole non-magnetic water meter can be only used as an unqualified product, so that resource waste is caused.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The following describes the technical scheme in the embodiment of the present disclosure with reference to attached figures in the embodiments of the present disclosure. Referring to FIG. 1, FIG. 1 is a structural schematic diagram of a non-magnetic metering testing device provided by the embodiment of the present disclosure. The non-magnetic metering testing device comprises: [0032] a base 11; a rotating speed mechanism 12, the rotating speed mechanism comprising a driver 121, a coupling shaft 122 and an induction wheel 123, the bottom of the driver 121 being connected with the base 11, the driver 121, the coupling shaft 122 and the induction wheel 123 being sequentially connected, the coupling shaft 122 being used for being matched with the driver 121 to drive the induction wheel 123 to rotate, and the induction wheel 123 being used for rotating under the effect of the driver so as to simulate the rotating speed of water flow; a non-magnetic sensor 13, the non-magnetic sensor 13 being arranged on supporting plates of the base 11 and being used for sampling non-magnetic metering data; and a glass sheet 14, the glass sheet 14 being arranged between the induction wheel 123 and the non-magnetic sensor 13.

[0033] Exemplarily the driver 121, the coupling shaft 122 and the induction wheel 123 can be vertically connected in sequence upwards. The coupling shaft 122 serves as a fixing element to fix the induction wheel 123 to the driver 121 so as to simulate the actual use process of the non-magnetic water meter. Preset distances exist among the non-magnetic sensor 13, the glass sheet 14 and the induction wheel 123. By sampling non-magnetic metering data, the non-magnetic sensor records a non-magnetic induction distance interval and a non-magnetic signal intensity interval range so as to detect whether the non-magnetic water meter is qualified or not.

[0034] Wherein, the driver 121 can be a direct current motor or other electronic devices for generating driving torque. The glass sheet 14 can be tempered glass or organic glass. Glass made of various materials in the current market is used as a pressure-bearing element of the non-magnetic water meter, and the organic glass is applied to the water meter due to the fact that the non-magnetic water meter has strict requirements for the detection distance. The organic glass has the advantages of high strength and small size. Under the same static pressure condition, the thickness of the organic glass can be lower than that of the tempered glass, so that the distance between a metal pointer and a non-magnetic module can be shortened. However, the organic glass is expensive, and the time for applying the organic glass to the water meter is short. In addition, the organic glass in the current market is made of various materials, even if the organic glass is made of the same material and is different in adopted models, the dielectric coefficients of various kinds of glass are different, and a certain influence can be generated on non-magnetic signals.

[0035] According to the non-magnetic metering testing device 10 provided by the present disclosure, the glass sheet 14 is additionally arranged between the induction wheel 123 and the non-magnetic sensor 13, so that the non-magnetic metering testing environment is closer to the actual use process of the non-magnetic water meter, and the influence on the non-magnetic signals when the non-magnetic water meter selects glass made of various materials as the pressure-bearing element in the actual use process is simulated. Therefore, non-magnetic detection is carried out by using the non-magnetic metering testing device 10 disclosed by the present disclosure, so that the detection accuracy can be improved.

[0036] Optionally, the non-magnetic metering testing device 10 in the present disclosure further comprises a distance adjusting mechanism 15, the distance adjusting mechanism 15 comprises a connecting part 151, locking pieces 152, a first supporting plate 153 and a second supporting plate 154, the distance adjusting mechanism 15 is connected with the base 11 through the connecting part 151, the first supporting plate 153 and the second supporting plate 154 arc rotatably arranged on the connecting part 151 through the locking pieces 152, the locking pieces 152 are used for limiting vertical movement and horizontal rotation of the first supporting plate 153 and the second supporting plate 154, and the first supporting plate 153 is located below the second supporting plate 154; the first supporting plate 153 is used for accommodating the glass sheet 14; and the second supporting plate 154 is used for fixing the non-magnetic sensor 13.

100371 Exemplarily, the connecting part 151 can be of a cylindrical structure to facilitate rotation of the first supporting plate 153 and the second supporting plate 154 on the connecting part 151. The locking piece 152 can be a buckle around the connecting part 151. The locking piece 152 can be fixed to the connecting part 151 by closing the buckle. A pressure plate 1541 can be arranged on the second supporting plate 154. The second supporting plate 154 is matched with the pressure plate 1541 to stabilize the non-magnetic sensor 13.

I 0038] Exemplarily, after the non-magnetic sensor 13, the glass sheet 14 and the induction wheel 123 are placed at planned positions, the optimal distance is found after the positions are adjusted by the distance adjusting mechanism. Thc influence of these elements on the induction capability can he tested by changing different induction wheels 123, glass sheets 14, and non-magnetic sensors.

[0039] Therefore, the distance adjusting mechanism 15 is arranged on the non-magnetic metering testing device 10. The distances among the non-magnetic sensor 13, the glass sheet 14 and the induction wheel 123 can be flexibly adjusted. The rotatable supporting plates are arranged on the connecting part 151, the phenomenon that the induction wheel, the glass or the non-magnetic sensor cannot be taken out due to space limitation is avoided, and testing materials are convenient to replace, so that the detection efficiency is improved.

[0040] Optionally, the connecting part 151 is provided with an electronic scale and a limiting groove, the electronic scale is used for reading the positions of the first supporting plate153 and the second supporting plate 154, and the limiting groove is used for limiting the horizontal positions of the first supporting plate 153 and the second supporting plate 154.

[0041] Therefore, the electronic scale ruler is arranged on the connecting part 151, so that the positions of the first supporting plate 153 and the second supporting plate 154 can be conveniently read, the relative distance can be conveniently calculated, and the limiting groove is formed in the connecting part 151, so that the non-magnetic sensor 13 and the glass sheet 14 can be prevented from being out of the vertical induction range due to the fact that the rotation angle of the first supporting plate 153 or the second supporting plate 154 is too large.

[0042] Optionally, the rotating speed mechanism further comprises a speed adjusting switch 16 and a displayer 17, the speed adjusting switch 16 is used for adjusting the rotating speed of the driver 121, and the displayer 17 is used for displaying the rotating speed of the driver 121. When the rotating speed of the driver is detected to be abnormal, the abnormal rotating speed can be observed in time through the displayer and controlled through a rotating speed switch.

[0043] Therefore, the speed adjusting switch 16 and the displayer 17 are arranged on the non-magnetic metering testing device 10, and the rotating speed of the driver 121 can be controlled in real time, so that the detection accuracy is improved.

[0044] In addition, a power switch 18 can be further arranged on the non-magnetic metering testing device 10. The starting of the driving motor is controlled through die power switch 18, so that the detection progress can be conveniently controlled.

[0045] Optionally, the non-magnetic metering testing device 10 further comprises a main control board 19, and the main control board 19 is used for metering pulses of the non-magnetic sensor and pulses of the induction wheel and sending test results to a control terminal, [0046] Further, the main control board I 9 can also control the rotating speed of the driving mechanism and adjust the distance of the distance adjusting mechanism 15 according to instructions or a server. Moreover, the results are transmitted to the server through a communication port. The main control board 19 can also read an instruction of the terminal, and non-magnetic metering reliability evaluation, non-magnetic metering unit device evaluation and batch production non-magnetic sensor qualification evaluation are achieved according to a preset detection process.

[0047] In addition, the existing mechanism is single testing equipment, and a proper distance range of the non-magnetic sensor and the semi-metal induction wheel can be simulated and tested by a single machine only. A communication interface for connecting the non-magnetic metering testing device with the server can be further added, and a test conclusion can be uploaded to produce a wireless grid (MESH) system, so that subsequent tracking of detection data in the production process is facilitated, and production problem solving is assisted. When the device is used for incoming material inspection, incoming material inspection records can be conveniently recorded, and the problem of manual data recording is reduced.

[0048] Therefore, the main control board 19 is arranged on the non-magnetic metering testing device 10, the test results are sent to the terminal through the main control board, and detection steps are carried out according to instructions of the terminal, so that the non-magnetic metering testing efficiency can be improved.

[0049] Further, the non-magnetic metering testing device 10 provided by the present disclosure can also be used for detecting whether the non-magnetic sensor is qualified or not during batch production, so that the risk of bad rework after the non-magnetic sensor is online is reduced.

[0050] Optionally, a universal asynchronous receiver/transmitter (1.1ARI) interface (unshown in the figures) is arranged on the main control board 19, the main control board reads the non-magnetic induction intensity through the UART interface, and whether the distance between the non-magnetic sensor and the induction wheel is in an effective interval range or not is judged based on the non-magnetic induction intensity. [0051] Wherein, an existing device can only compare rotating speed values sensed by non-magnetic sensors at different intervals with rotating speed readings of a metering mechanism. The UART interface cannot read the induction intensity value of the non-magnetic sensor through a serial port, so that a proper design interval value of the distance between the non-magnetic sensor and the semi-metal pointer can be obtained only by mechanically comparing the rotating speed value, and the interval value is difficult to actually measure after the whole meter is assembled in the actual production process. In the design stage, the interval value of a non-magnetic induction intensity signal in a proper distance range is obtained through testing by combining the induction wheel 123, the non-magnetic sensor 13 and the glass sheet 14, Therefore, in the production process, whether the assembly size of the whole meter goes wrong or not and whether the distance between the non-magnetic sensor and the semi-metal pointer is within a proper interval range are judged by reading the non-magnetic induction intensity.

[0052] In the scheme provided by the present disclosure, a pulse metering method is adopted for metering data. Compared with the rotation turn number pulse of the induction wheel 123 and the non-magnetic induction metering pulse value, the verification error can be reduced to +/-1 pulse interval, and the requirement that the electromechanical conversion error +/-1 pulse is required for water meter type evaluation detection is better met.

[0053] Therefore, the UART interface is arranged on the main control board 19, so that the non-magnetic induction intensity can be directly read, and the non-magnetic detection efficiency is improved.

[0054] Optionally, the distance adjusting mechanism 15 further comprises a stepping motor, and the distance adjusting mechanism 15 is driven by the stepping motor to adjust the positions of the first supporting plate 153 and the second supporting plate 154.

[0055] Wherein, the stepping motor is an actuating mechanism for converting electric pulse into angular displacement. When the stepping motor receives a pulse signal, the stepping motor is driven to rotate by a fixed angle (called a step angle) according to a set direction, and the rotation of the stepping motor is carried out step by step at the fixed angle. The angular displacement can be controlled by controlling the number of pulses; and the rotation speed and acceleration of the motor can also be controlled by controlling the pulse frequency, so that speed adjustment and positioning are carried out. [0056] Therefore, the distance adjusting mechanism 15 is driven by the stepping motor to adjust the positions of the first supporting plate 153 and the second supporting plate 154, so that the non-magnetic metering testing device can automatically record a non-magnetic induction distance interval and a non-magnetic signal intensity interval range. In addition, the requirement for accurately adjusting the distance can be met. The testing time can be reduced, and the testing accuracy is increased.

[0057] In the second aspect, the embodiment of the present disclosure further provides a non-magnetic metering testing method. Referring to FTC. 2, FIG. 2 is a schematic diagram of steps of a non-magnetic metering testing method provided by the embodiment of the present disclosure. The method comprises the following steps: [0058] in step S21, respectively mounting a non-magnetic sensor to be tested, a glass sheet and an induction wheel on the non-magnetic metering testing device in the first aspect; [0059] in step S22, adjusting the distances among the non-magnetic sensor, the glass sheet and the induction wheel; and [0060] in step S23, starting the non-magnetic metering testing device to detect whether the non-magnetic sensor is qualified or not.

[0061] Distance adjustment of the existing non-magnetic sensor and semimetal pointer is achieved manually. When the induction distance range of non-magnetic induction wheels made of different sizes is measured, manual repeated adjustment is needed, a proper interval value is obtained, and the automation degree is low. Moreover, by using the non-magnetic metering testing device 10 disclosed by the present disclosure to carry out non-magnetic detection, the metal material, the diameter, the height, the glass material and the thickness of the induction wheel can be rapidly and accurately evaluated and tested in the design stage.

[0062] Optionally, the method further comprises the following steps: (00631 replacing at least one of the non-magnetic sensor, the glass sheet and the induction wheel, and detecting the influence of at least one of the non-magnetic sensor, the glass sheet and the induction wheel on the non-magnetic metering.

10064] Therefore, by means of the method, the component to be tested can be placed at the corresponding position in the non-magnetic metering testing device 10, so that batch non-magnetic induction detection can be carried out, the testing time can be effectively shortened, and the testing efficiency call be improved.

[0065] In addition, the present disclosure also provides a non-magnetic metering reliability evaluation method. Referring to FIG. 3, FIG. 3 is schematic diagram of steps of non-magnetic metering reliability evaluation steps provided by the embodiment of the present disclosure.

[0066] After the non-magnetic sensor 13 to be tested, the induction wheel 123 and the glass sheet 14 are placed in the non-magnetic metering testing device 10, the server controls the rotating speed mechanism 12 to rotate within a preset flow speed range, the difference between non-magnetic metering and synchronous wheel metering is compared. If the deviation is smaller than +/-1, the distance between the first supporting plate 153 and the second supporting plate 154 is increased, testing is continued, and the non-magnetic metering is inaccurate until the difference between the two metering is greater than +A, and the distance between the induction wheel 123 and the non-magnetic sensor and the signal intensity value of the non-magnetic module are automatically recorded at the moment.

[0067] According to the recorded data, the range of effective metering distance and signal intensity of the non-magnetic metering under the condition that the current non-magnetic sensor 13, induction wheel 123 and glass sheet 14 are combined can be effectively evaluated. According to the range and in combination with the tolerance of system structure design, whether the non-magnetic metering combination under the current combination has enough design allowance or not and whether the batch production requirement is met or not can be effectively evaluated.
