Description

Technical Field

[0001] This utility model belongs to the field of remote meter reading technology, specifically relating to a remote meter reading device for water meters. Background Technology

[0002] With the rapid development of my country's economy, tap water has entered thousands of households. Water meters are essential in the use of tap water. Water meters work by generating torque through the impact of water flow on their internal impellers, causing the impellers to rotate. Currently, the most widely used type is the mechanical water meter. At the end of the month, staff need to visit each household to read the water meter readings. This manual recording method results in a large workload for staff and low meter reading efficiency. Therefore, there is a need for a remote meter reading device that can read water meters without the need for staff to manually read the meters. This utility model addresses this technical problem. Utility Model Content

[0003] This utility model provides a remote meter reading device for water meters, which can realize automatic meter reading function, eliminating the need for staff to read meters on-site, reducing the labor intensity of staff, and improving the efficiency of meter reading work.

[0004] A remote meter reading device for water meters includes a support mechanism connected to the water meter dial, a camera mechanism connected to the support mechanism, and a data transmission mechanism electrically connected to the camera mechanism. The support mechanism is used to amplify the reading on the dial and support the camera mechanism. The camera mechanism is used to periodically capture the reading. The data transmission mechanism is used to transmit the collected data to a terminal device.

[0005] Furthermore, the support mechanism includes a transparent support block connected to the dial, and the shooting mechanism is connected within the support block.

[0006] Furthermore, the shooting mechanism includes a miniature camera connected within the support block, and the miniature camera is electrically connected to the data transmission mechanism.

[0007] Furthermore, the data transmission mechanism includes a PCB circuit board electrically connected to the camera and an IoT card connected to the PCB circuit board, the IoT card being used for data transmission.

[0008] Furthermore, the support block has an opening slot, the data transmission mechanism is connected in the opening slot, and the shooting mechanism is connected in the groove.

[0009] Furthermore, the side of the support block is provided with a cross-section, which is used for manual observation of the dial reading.

[0010] The technical effects of this utility model are as follows:

[0011] (1) This device uses a shooting mechanism to periodically photograph the readings on the water meter dial and transmits the data to the terminal device through a data transmission mechanism to complete the automatic data collection. This eliminates the need for staff to perform meter reading on-site, realizes remote automatic meter reading, reduces the labor intensity of staff, and improves meter reading efficiency.

[0012] (2) Since the miniature camera is located inside the support block and the side of the support block is a curved surface, the shape of the captured reading will be larger than the shape displayed on the dial, thus enabling the reading to be captured clearly and avoiding unclear images.

[0013] (3) The support block in this scheme not only plays a magnifying role, but also fixes the miniature camera. Furthermore, the side has a cut surface, which helps the staff to see the reading clearly through the cut surface, thus achieving a multi-functional effect. Attached Figure Description

[0019] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments and accompanying drawings.

[0020] Example 1

[0021] See Figure 1 , Figure 2A remote water meter reading device includes a support mechanism connected to the water meter panel 1, a camera mechanism connected to the support mechanism, and a data transmission mechanism electrically connected to the camera mechanism. The support mechanism is used to magnify the reading on the meter panel 1 and support the camera mechanism. The camera mechanism is used to periodically capture the readings. The data transmission mechanism is used to transmit the collected data to a terminal device 7. In this embodiment, the terminal device 7 can be a computer, a mobile phone, or other terminals, and staff can view the collected readings through a mobile app.

[0022] Furthermore, the support mechanism includes a transparent support block 2 connected to the dial 1, and the shooting mechanism is connected inside the support block 2. In this embodiment, the support block 2 can act as a magnifying glass to magnify the reading on the dial 1.

[0023] Furthermore, the shooting mechanism includes a miniature camera 4 connected within the support block 2, and the miniature camera 4 is electrically connected to the data transmission mechanism. Specifically, a cavity for accommodating the miniature camera 4 can be opened in the support block 2, and then the miniature camera 4 can be placed inside the cavity with the shooting direction facing the curved side of the support block 2.

[0024] In this embodiment, the support block 2 is a cylindrical resin, and the bottom surface of the resin does not cover the top of the reading on the dial 1, so that when the operator observes the reading through the resin, the resin will magnify the reading.

[0025] Furthermore, the data transmission mechanism includes a PCB circuit board 5 electrically connected to the camera and an IoT card 6 connected to the PCB circuit board 5. The IoT card 6 is used for data transmission. This solution can also upload data to the cloud, and the collected data can be used for statistical analysis and other tasks related to data from the waterworks.

[0026] Furthermore, the side of the support block 2 is provided with a cut surface 3, which is used for manual observation of the reading on the dial 1. In this embodiment, the cut surface 3 is an inclined plane. Under normal circumstances, when the staff observes the reading, the staff and the reading are located on opposite sides of the support block 2. The light of the reading itself first needs to pass through one side of the support block 2 to be magnified, and after magnification, it will pass through the other side of the support block 2 before reaching the human eye. Therefore, it will pass through the side of the support block 2 twice. When both sides of the support block 2 are curved, the staff will have difficulty seeing the reading on the dial 1. Therefore, the side of the support block 2 in this solution is provided with a cut surface 3, so that the light of the reading itself will only pass through the curved side once in the process of reaching the human eye. The cut surface 3 is a plane, so that the staff can see the reading clearly.

[0027] The working process of this embodiment is as follows:

[0028] The miniature camera is controlled to periodically capture the readings on the dial 1. The support block 2 makes the readings captured by the miniature camera larger and clearer. The captured image data is transmitted to terminal devices 7 such as computers and mobile phones and the cloud via the IoT card 6, thereby enabling the terminal devices 7 to collect data. When the miniature camera 4 malfunctions and staff need to read the meter on-site, the staff can observe the readings through the cross-section 3 of the support block 2. In this way, the device will not affect the staff's meter reading work.

[0029] Example 2

[0030] See Figure 3 , Figure 4 Based on Embodiment 1, this solution also provides another embodiment, the details of which are as follows:

[0031] The support block 2 has an opening slot 8, the data transmission mechanism is connected in the opening slot 8, and the shooting mechanism is connected in the groove 10.

[0032] Preferably, in this embodiment, the support block 2 is semi-cylindrical and covers half of the dial 1, so that the edge of the curved part of the bottom surface can fit with the edge of the dial 1.

[0033] Furthermore, in this embodiment, the support block 2 is provided with a plurality of connecting ears 9 on its side. The connecting ears 9 are fitted with the dial 1. Preferably, in this embodiment, the support block 2, the connecting ears 9 and the dial 1 can be processed by integral injection molding to achieve integration.

[0034] The miniature camera still shoots in the direction of the reading, and staff can choose either Embodiment 1 or Embodiment 2 based on actual needs. Although Embodiment 2 makes it difficult to achieve a magnification effect, it can still capture and record the reading.

[0035] The above embodiments are merely preferred embodiments of this utility model. Those skilled in the art can obtain other embodiments from the above embodiments without creative effort. Therefore, this application protects not only the above embodiments, but also the scope consistent with the principles and features of this application.
