Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Example 1
In order to avoid the abnormal situation of the metering device in operation of the water meter in the use process due to the abnormal internal calibration parameters or the abnormal phenomenon of external artificial attack, and realize the automatic calibration of the water meter metering device, thereby ensuring the accuracy of the metering device, the utility model discloses a double-electromechanical conversion Internet of things water meter, please refer to fig. 1, which is a structural schematic diagram of the double-electromechanical conversion Internet of things water meter, comprising: a controller and a base table, wherein the controller comprises a magnetic sampling module, a non-magnetic sampling module and a controller main board 12.
In this embodiment, the magnetic sampling module and the nonmagnetic sampling module are electrically connected with the controller motherboard 12, wherein the magnetic sampling module obtains the first water flow information of the base table 5 by means of magnetic sampling, the nonmagnetic sampling module obtains the second water flow information of the base table 5 by means of nonmagnetic sampling,
when the non-magnetic sampling module is in metering error due to the attack of an external radio frequency signal, the controller main board 12 takes the first water flow information of the magnetic sampling module as the reference; when the magnetic sampling module measures errors due to external strong magnetic attack, the controller main board 12 is based on the second water flow information of the non-magnetic sampling module. It should be noted that, in this embodiment, whether the magnetic sampling module has a metering error is determined according to a preset error threshold, and when the sampling error is greater than the preset error threshold, the metering error is considered to have occurred; and when the sampling error is smaller than a preset error threshold value, the metering error is not considered to occur. In addition, the embodiment judges whether the non-magnetic sampling module has metering errors according to the detection frequency threshold, and when the counting frequency of the non-magnetic sampling module exceeds the preset frequency threshold or is not counted for a period of time, the metering errors are considered to occur; and when the counting frequency is smaller than the preset frequency threshold value, the counting error is not considered to occur.
The Internet of things water meter with double electromechanical conversion provided by the utility model adopts double combination of magnetic sampling and non-magnetic sampling, and metering cannot be influenced even if one sampling mode fails, complementation can be formed, measurement errors caused by single interference of a magnetic field or a radio frequency signal cannot be avoided, and abnormal operation of the water meter caused by external artificial attack or abnormal internal calibration parameters can be avoided.
Further, in the embodiment of the present utility model, as shown in fig. 2 and 3, the nonmagnetic sampling module includes a nonmagnetic pointer 1 and a nonmagnetic sampling circuit board 2 corresponding to the nonmagnetic pointer 1, wherein, referring to fig. 4, the nonmagnetic pointer 1 is connected to a first gear shaft 301 of a gear set 3 meshed with a sampling impeller 4, and the sampling impeller 4 is installed in a base table 5. It should be noted that, unlike the magnetic induction module, the nonmagnetic sampling module is not detected by magnetic induction, but the amplitude of the radio frequency signal generated by the LC resonant circuit is attenuated under the influence of the nonmagnetic pointer 1, and the measurement is realized by detecting the rotation direction and the rotation times of the nonmagnetic pointer 1, so that the ferromagnetic attack has no effect on the nonmagnetic measurement module.
Further, the water meter comprises a first shell 6 and a second shell 11, the controller main board 12 is arranged in the second shell 11, a first accommodating part 7 is arranged on one side of the first shell 6, the nonmagnetic sampling circuit board 2 is arranged in the first accommodating part 7, and the nonmagnetic pointer 1 is arranged right below the first accommodating part 7. Preferably, the first accommodating portion 7 is detachably connected to the first housing 6.
Further, in the embodiment of the present utility model, the magnetic sampling module includes a signaling pointer 8 and a hall sampling circuit board 9 corresponding to the signaling pointer 8, where the signaling pointer 8 is connected to the second gear shaft 302 of the gear set 3. It should be noted that, when water flows through the water meter, the sampling impeller 4 is driven to rotate along with the water meter, and when the sampling impeller 4 has the magnetic signaling pointer 8 close to the hall sampling circuit board 9, a changing electric signal is generated due to the hall effect. Therefore, when water continuously flows, a pulse signal can be obtained, the signal is converted into the rotating speed or the water flow speed of the rotor in different time periods through the Hall sampling circuit board 9, and the water flow in the time period is obtained according to the area and the time of the flowing water, so that the purpose of measuring the water consumption is achieved.
Further, a second accommodating portion 10 is provided on the other side of the first housing 6, the hall sampling circuit board 9 is disposed in the second accommodating portion 10, and the signaling pointer 8 is disposed directly under the second accommodating portion 10. Preferably, the second receiving portion 10 is detachably connected to the first housing 6.
Referring to fig. 5, the first housing 6 includes a first chamber 601 for accommodating the gear set 3, a second chamber 602 for accommodating the nonmagnetic pointer 1 and the signaling pointer 8, and a third chamber 603 for accommodating the first accommodating portion 7 and the second accommodating portion 10, and a partition is disposed between the chambers.
In addition, the water meter further comprises a signal antenna, no matter hall sampling abnormality or no magnetic sampling abnormality, the controller main board 12 reports warning information to the management system through the signal antenna, and maintenance personnel are reminded to maintain the water meter in time.
In summary, the sampling mode combining magnetic sampling and nonmagnetic sampling has the advantages of both magnetic sampling and nonmagnetic sampling, and can more effectively resist various external attacks or interferences. When one sampling mode fails, the normal operation of the water meter is not affected, and the operation is more reliable. In general, the nonmagnetic sampling precision is higher, and the sampling information is based on nonmagnetic sampling; when no magnetic sample fails or is subject to external disturbance, the magnetic sample is subject to control. When any sampling mode fails or is interfered by the outside, the water meter can send alarm information to remind maintenance personnel to maintain the water meter in time.
The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
