Content Description
The invention relates to the technical field of pipeline valves, in particular to an intelligent water meter based on remote monitoring technology.
Background of the invention
At present, the Internet of Things meter is a new type of water meter that uses modern microelectronic technology, modern sensing technology, and smart IC card technology to measure water consumption, and uses water data transmission and settlement transactions. Compared with traditional water meters with flow collection and mechanical pointers displaying water consumption, the Internet of Things meter has more advantages in terms of functionality. The user can use the software to read and record the user's water consumption, and can also control the water consumption according to the agreement.
Traditional water meters can only calculate the amount of water used by the metering mechanism of the impeller. They cannot notify the user of the amount of water by wire and wireless at any time, so that they have to read the water meter every time. This inconveniences the use of workers and people. , And most of the water meters use cast iron material, but this type of iron watch is very easy to rust or even damage.
The existing Internet of Things meter includes electronic modules that can achieve the above functions. The signal transmission between each functional unit is completely realized by cables, which makes it easy to affect the other units when the controller is disassembled and installed. Usually, the meter is made of water meters. A whole. However, in the existing whole-table components, the failure rate of the electronic components of the water meter is relatively high. When the internal electronic module is damaged, the total water valve of the user needs to be shut down first, and then the entire water meter is removed, and then the maintenance or the replacement is performed. , The maintenance cost is high and it will affect the user's normal water use.
Summary of the Invention
The purpose of the present invention is to provide an intelligent meter for Internet of things based on a remote monitoring technology to overcome the above technical drawbacks.

Figure is a front view of the invention
The technical solution adopted by the present invention for the above problems is: an intelligent water meter for Internet of Things based on a remote monitoring technology, including a transmission mechanism component, an electronic module component, a sensor, a base surface, and an outer cover body. The electronic module component passes the cable and the transmission mechanism. The components are connected and the sensors are respectively connected with the electronic module assembly and the base meter. The transmission mechanism components, the electronic module components, the sensors and the base meter are all located inside the outer housing.
As a further improvement of the above technical solution, the electronic module assembly includes a wireless communication module wirelessly connected to the water supply company. The sensor detects the reading of the water quantity signal of the base meter, and transmits the water quantity signal to the electronic module assembly. Then, the electronic module assembly transmits the user's water consumption to the water supply company through the wireless communication technology, so as to realize the remote collection water meter; and the transmission mechanism The component is connected to the water meter switch valve and the trigger operation can be performed on the drive mechanism component through the electronic module assembly to achieve the function of remotely controlling the water meter switch valve.
The base watch includes a water meter movement, a watch glass and a watch cover. The watch glass is located above the movement of the water meter. The cover covers the movement of the water meter and the watch glass, and the sensor is electrically connected with the water meter movement. The outer cover body includes a lower cover body and an upper cover body. The lower cover body is mounted on the base table housing assembly, and the upper cover body and the lower cover body are detachably connected. The cover body is made of plastic material. The plastic upper cover body and the lower cover body can be sealed on the internal base table and other components, and can play a good role of waterproof, dustproof and protection, and effectively prevent rust corrosion or damage of the internal cast iron or other metal components.
The lower cover body and the upper cover body are connected to each other by a mounting screw, and an assembly screw is attached to the joint of the lower cover body and the upper cover body from above or from the side. Corresponding screw holes are respectively provided at the connection positions of the upper cover body and the lower cover body, and the upper screw cover and the lower cover body are connected together by the upper part or the side screw of the assembly screw, so as to connect the upper cover body and the lower cover body together. In the technique of mounting screws from bottom to top, the connection method according to the embodiment of the present invention can facilitate the installation and disassembly of the assembly screws. Mounting screws are vertically disposed at the corners of the lower and upper covers. There is a tamper-proof cap on the top of the mounting screw. By installing a tamper-evident cap, the Internet of Things meter can be effectively prevented from being disassembled and the meter can be effectively protected. The outer cover body is provided with a battery assembly for supplying power to the electronic module assembly and the sensor. The battery assembly can also be provided with an opening facing the side or above, so as to facilitate the installation or removal of the battery, and the replacement battery is convenient to operate.
The length of the connecting cable is greater than the height of the outer cover. When the electronic module assembly needs to be replaced or repaired, the upper cover body is opened, and when the connection cable between the electronic module assembly and the transmission mechanism assembly is long enough, the electronic module assembly can be conveniently removed and replaced or repaired. At the same time, the maintenance cost of the water meter is reduced, and the water valve does not need to be cut off, which will not affect the user's normal water use.
The beneficial effect of the present invention is that by using the upper and lower cover bodies that are detachably connected, not only the performance and the service life of the internal electronic devices can be improved, but also the upper cover body can be conveniently disassembled to replace the electronic module components. The Internet of Things meter of the invention facilitates after-sales personnel to perform on-site maintenance, and can replace and maintain the electronic module components of the Internet of Things, without disassembling the entire watch and without shutting down the water for residents, so that the maintenance work is more convenient and time-saving. Reduce maintenance costs without affecting users' normal water use.

10 Layer PCB

10 Layer PCB Stack Up thickness, Design and manufacturing


Usually, 10 layer PCB is HDI PCB board, but some are not.


10 Layer PCB Stack Up And Design


Regardless of the number of layers constituting the circuit board design, pad spacing, clearance, trace widths, copper weights and drill hole sizes must be tailored to your contract manufacturer (CM). If your design requires multiple layers, you need to consider additional DFM specifications for signals through vias, power and ground wiring, and PCB stackup.

For 10-layer PCB manufacturing, it is necessary to determine the number of layers, their arrangement or stacking, and the type of material. These choices require coordination between thickness constraints; material parameters; such as dielectric constant, thermal expansion coefficient and electrical strength; signal type isolation and drilling options. For PCB assembly, wiring options and their impact on welding process are very important. The function of CM limits the choice of vertical aspect of design.

When your PCB needs six layers of routing, you should choose to use ten layers of PCB. Because ten-layer circuit boards usually have six signal layers and four planes. Of course, we do not recommend the design of more than six signal layers on the 10-layer circuit board. Ten layers are also the largest number of layers, which can be easily manufactured on 0.062 inch thick sheets. Occasionally you will see a 12-layer PCB made of 0.062 inch thick board, but there are not many manufacturers who can make 12-layer circuit boards. Just right, besides making 10-layer circuit boards, we also have very rich experience in manufacturing 12-layer circuit boards.

High layer count boards (10 +) require thin dielectrics (usually 0.006 or smaller on 0.062 thick plates), so they are automatically tightly coupled. After stacking and wiring properly, they can meet all our goals and have excellent EMC performance and signal integrity.

This is a very common and nearly ideal 10 layer PCB stack up.

The reason why this stack has such good performance is the tight coupling between signal and return plane, the existence of high-speed shielding signal layer, multiple grounding layers, and tightly coupled power supply/grounding layer pairs in the center of circuit board.

This 10-layer PCB stacking up method abandons closely spaced power/ground pairs. In return, it provides three signal routing layer pairs, shielded by the ground layer on the outer layer of the board, and isolated from each other through the internal power supply and the ground layer.

This 10-layer PCB stackup allows the routing of orthogonal signals near the same plane, but in the process, the closely spaced power/ground plane must also be abandoned.

In addition, we list some other stacking methods of 10-layer circuit boards for your reference.
