Hereby, the technical content and detailed description of the present invention are described as follows in conjunction with the drawings: please refer to FIG. 1 which is a block diagram of the system architecture of the intelligent water meter system of the present invention. The smart water meter system 100 communicates with the regional base station 200, and the smart water meter system 100 includes a plurality of smart water meters 1-1˜1-n. Wherein, the regional base station 200 is, for example but not limited to, a base station 200 set up by a water company (it may be a cloud server platform or a remote monitoring system set up by a water company). The smart water meters 1-1~1-n are water meters with a wireless transmission function, and the data recorded by them can be transmitted by wireless transmission. Different from the water meters without the traditional wireless transmission function, the smart water meters 1-1~1-n do not need the water company to assign a special person to perform the meter reading operation, but directly transmit the data to the water company through wireless transmission. The regional base station 200 is set up to save time and labor cost due to running around. It is worth mentioning that in one embodiment of the present invention, although the smart water meter system 100 of the present invention mainly uses wireless transmission to transmit data, it can also use wired transmission to transmit data in certain specific situations, so This is not the limit.

Each smart water meter 1-1~1-n is set up on the user end, which is usually set up on the water supply pipeline A of individual users such as households or businesses, and measures the fluid data If of the water supply pipeline A (generally for self-employed water consumption, but may include data such as, but not limited to, velocity, flow, and even water quality). Each smart water meter 1-1~1-n integrates its own fluid data If and hardware data Ih into water meter data Iw, and generates a weight parameter Pw according to the water meter data Iw. Wherein, hardware data Ih is for example but not limited to intelligent water meter 1-1~1- Information such as number and power of n, and weight parameters Pw such as but not limited to parameters such as communication quality will be further described later.

When the smart water meters 1-1~1-n want to send water meter data Iw, the smart water meters 1-1~1-n will first communicate with the adjacent smart water meters 1-1~1-n, so that the adjacent The smart water meters 1-1~1-n know each other's weight parameter Pw. Wherein, usually, the better the communication quality, the more adjacent, but not limited thereto. Then, the smart water meters 1-1~1-n select one of them as the master transmission water meter according to the weight parameters, and the rest are slave transmission water meters. Wherein, the main transmission water meter is usually a water meter with better communication quality with the regional base station 200 . Then, the smart water meters 1-1~1-n establish a transmission connection by connecting with one of the adjacent ones according to the weight parameter Pw. The transmission connection mainly defines the wireless transmission relationship of smart water meters 1-1~1-n, and its main connection method is that a single smart water meter 1-1~1-n will only provide data to a single smart water meter 1 -1~1-n, connect all smart water meters 1-1~1-n in series.

After the transmission connection is established, the slave transmission water meter transmits its own water meter data Iw to the connected slave transmission water meter according to the transmission connection line, and transmits it to the final master transmission water meter according to the connection relationship. Finally, the master transmission water meter integrates the water meter data Iw of each slave transmission water meter and the water meter data Iw to which it belongs to the total area data Is, and transmits the total area data Is to the regional base station 200, so that the regional base station 200 knows each The usage status of the smart water meters 1-1~1-n. It is worth mentioning that in one embodiment of the present invention, the water meter data Iw is usually the data to be transmitted to the regional base station 200, and the weight parameter Pw is usually a parameter for communication and judgment of the smart water meters 1-1~1-n. The smart water meters 1-1~1-n can transmit the weight parameter Pw at the same time for reference when transmitting the water meter data Iw (and vice versa), or only transmit the water meter data Iw separately. The power consumption and transmission time of the water meters 1-1~1-n are considered comprehensively.

Please refer to FIG. 2A which is a circuit block diagram of the smart water meter of the present invention, and refer to FIG. 1 for the combination. Each smart water meter 1-1~1-n (indicated by smart water meter 1-1) includes a communication module 10, a measurement module 12 and a controller 14, and the communication module 10 and the measurement module 12 are coupled Connect to controller 14. The communication module is used to transmit the water meter data Iw, the weight parameter Pw and the total area data Is (if the smart water meters 1-1~1-n belong to the main smart water meter), and the measurement module 12 is used to measure the fluid data If. The controller 14 is used to detect the hardware data Ih belonging to itself, and integrate the fluid data If and the hardware data Ih into the water meter data Iw, so as to generate the weight parameter Pw according to the water meter data Iw.

Each smart water meter 1-1~1-n further includes a memory module 16 and a battery 18, the memory module 16 is coupled to the controller 14, and the battery 18 is used to supply the operating place of the smart water meter 1-1~1-n required electricity. The memory module 16 is used to store the fluid data If, the hardware data Ih, the weight parameter Pw, and the water meter data Iw and the weight parameter Pw of one of the adjacent smart water meters 1-1~1-n received through the transmission line and other information. Even if it is the main transmission water meter at the transmission end, it still provides the water meter data Iw to one of the main transmission water meters adjacent to the main transmission water meter according to the weight parameter Pw. Wherein, the fluid data If can include related data such as water consumption, flow rate, flow velocity or water quality, and the hardware data Ih can include the electric quantity of the battery 18, the memory capacity of the memory module 16, the communication module 10 and the adjacent smart water meter 1 - the first transmission quality of 1~1-n (or one of the adjacent ones), the second transmission quality of the communication module 10 and the regional base station 200, the table number or house number quality and other relevant information. It is worth mentioning that in one embodiment of the present invention, the memory module 16 can be a device for storing data such as a memory or a hard disk.

The controller 14 can make part (or all) of the above-mentioned fluid data If and hardware data Ih into water meter data Iw (which mainly depends on the needs of the regional base station 200), and can combine the above-mentioned fluid data If and Part (or all) of the data in the hardware data Ih is made into a weight parameter Pw (which mainly depends on the selection method of the smart water meters 1-1~1-n). Furthermore, due to the smart water meters 1-1~1-n The installation location is usually not a place where power lines can easily pass, so usually the power supply must be additionally wired. However, in some remote areas, the location of the power line may be too far from the location where the smart water meters 1-1~1-n are installed, and additional wiring may require huge costs. Therefore, using the battery 18 to supply power and using remote monitoring of the power is a preferred implementation. In this way, the power consumption of the smart water meters 1-1~1-n must be reduced as much as possible, so as to prolong the service life of the smart water meters 1-1~1-n, and reduce the replacement speed of the battery 18.

Wherein, the power consumption difference is generally related to the remaining power of the battery 18 , the remaining capacity of the memory module 16 and the transmission quality. Therefore, the controller 14 usually uses the remaining power of the battery 18, the remaining memory capacity of the memory module 16, the communication module 10 and the adjacent smart water meters 1-1~1-n (or one of the adjacent) The first transmission quality or the second transmission quality between the communication module 10 and the regional base station 200 is used as the weight parameter Pw. The transmission connection generated by the weight parameter Pw can reduce the power consumption of the entire smart water meter system 100 , thereby prolonging the service life of the entire smart water meter system 100 .

Furthermore, the network side of the smart water meter system 100 mainly uses a self-healing network architecture, which can automatically restore the lost data of the smart water meters 1-1~1-n without human intervention. Specifically, the self-healing network architecture is mainly used for replacing old and new water meters, especially when the main transmission water meter happens to fail, the total area data Is can still be transmitted to the area base station 200 without interruption. When the water meter is replaced, the existing data of the old water meter can be updated to the new water meter without human intervention. The main reason is that the memory module 16 of each smart water meter 1-1~1-n not only memorizes the fluid data If and the hardware data Ih, but also memorizes one of the adjacent smart water meters received through the transmission line. Water meter data Iw of water meters 1-1~1-n. Therefore, when one of the smart water meters 1-1~1-n intends to replace the old water meter with a new water meter, the new water meter can receive the old water meter stored in the memory module 16 of the adjacent one of them through the transmission line. The water meter data Iw of the water meter can inherit the previous data of the old water meter.

When the main transmission water meter happens to fail, the subsequent selection results will no longer use the failed water meter as the main transmission water meter. Since the main transmission water meter provides water meter data Iw to one of the adjacent main transmission water meters (the weight parameter Pw can be used as the basis for judgment), when the main transmission water meter fails and the old water meter is replaced by a new water meter, the new water meter can receive The water meter data Iw of the old water meter stored in one of the memory modules 16 adjacent to the original main transmission water meter can inherit the previous data of the old water meter. Therefore, whether it is the main transmission water meter or the secondary transmission water meter that needs to be replaced, there is no need to update it through the regional base station 200, or manually update it through the maintenance personnel. The maintenance personnel only need to copy the water meter number and house number of the old and new water meters. In this way, the effect of easy maintenance and no need for repeated confirmation can be achieved.

It is worth mentioning that in one embodiment of the present invention, the data that can be used as the weight parameter Pw are, for example but not limited to, the remaining power of the smart water meters 1-1~1-n, the remaining memory capacity of the memory module 16 and the wisdom One or more of the transmission quality between the type water meters 1 - 1 - 1 - n and the adjacent water meters or the regional base station 200 . When more than one is used as the material of the weight parameter Pw, the percentage weight can be made according to actual needs. However, it is not limited thereto, as long as the factors that affect the transmission, the power consumption of the battery 18 or the capacity of the memory module 16 can be used as the weighting parameter Pw.

Referring again to FIG. 2A , each smart water meter 1 - 1 - 1 - n (shown as a smart water meter 1 - 1 ) further includes a display module 20 . The display module 20 is coupled to the controller 14, and the controller 14 can provide the water meter data Iw (which may include all or part of the fluid data If and the hardware data Ih) to the display module 20, so that the display module 20 displays its The numerical value is convenient for the on-site operator to know the current operating status of the smart water meter 1-1 visually and intuitively.

Please refer to FIG. 2B which is a structural diagram of the water meter of the smart water meter of the present invention, and refer to FIGS. 1-2A for the combination. Smart water meters 1-1~1-n (represented by smart water meter 1-1) are connected in series to the water supply pipeline A, and measure the fluid flowing from the first end E1 to the second end E2 (or the fluid flowing from the second end E2). E2 flows to the first end E1). Then Chi The controller 14 inside the smart water meter 1-1 provides the water meter information Iw to the display module 20, so that the on-site operator can visually know the current operating status of the smart water meter 1-1. It is worth mentioning that in one embodiment of the present invention, the display content on the display module 20 is only a schematic example, and the actual display content is not limited thereto.

Please refer to FIG. 3A , which is a schematic diagram of the signal transmission method of the first embodiment of the smart water meter system of the present invention, and refer to FIGS. 1-2B for complex cooperation. In this embodiment, the smart water meter system 100 includes 16 smart water meters 1-1~1-16, and each smart water meter 1-1~1-16 measures the fluid data If and The hardware data Ih is integrated into the water meter data Iw, and the weight parameter Pw is generated according to the water meter data Iw. Then, when the smart water meters 1-1~1-16 want to send the water meter data Iw, the smart water meters 1-1~1-16 will first communicate with the adjacent smart water meters 1-1~1-16, so that Adjacent smart water meters 1-1 to 1-16 know each other's weight parameter Pw. For example, but not limited to, the smart water meter 1-4 communicates with the smart water meters 1-3, 1-7, and 1-8 to know each other's weight parameter Pw, and so on.

After knowing the weight parameters Pw of each other, one of them is selected as the master transmission water meter according to the weight parameter, and the rest are slave transmission water meters. In this embodiment, since the weight parameter Pw of the smart water meter 1-1 is better, the smart water meters 1-1~1-16 recommend the smart water meter 1-1 as the main transmission water meter, and the smart water meters 1-2~1-16 1-16 is the slave transmission water meter. Then, the smart water meters 1-1 to 1-16 are connected to one of the adjacent ones according to the weight parameter Pw to establish a transmission connection. In this embodiment, the smart water meters 1-1 to 1-16 that have established transmission lines (as shown in dotted lines) represent better mutual transmission conditions (it may be the quality of the connection or the condition of its own hardware) better). For example but not limited to, the smart water meter 1-16 is connected with the smart water meter 1-12, which means that the transmission status of the smart water meter 1-12 and the smart water meter 1-16 is still relatively low compared with the smart water meter 1-11 and 1-15. Good to come. Then, the smart water meter 1-1 as the main transmission water meter provides the water meter data Iw to one of the adjacent main transmission water meters, which can be judged according to the weight parameter Pw. In this embodiment, the smart water meter 1-1 as the main transmission water meter provides the water meter data Iw to the smart water meter 1-2 according to the weight parameter Pw.

After the transmission connection is established, the slave transmission water meter transmits its own water meter data Iw to the connected slave transmission water meter according to the transmission connection line, and transmits it to the final master transmission water meter according to the connection relationship. Taking the smart water meter 1-13 as an example, the water meter data Iw of the smart water meter 1-13 is transmitted to the smart water meter 1-1 (main transmission water meter) through the smart water meter 1-9, 1-5, and other slave transmission water meters The same is true for the transmission method. Finally, the smart water meter 1-1 integrates the water meter data Iw of each secondary water meter and the water meter data Iw to which it belongs to the total area data Is, and transmits the total area data Is to the regional base station 200, so that the regional base station 200 can obtain Know the usage status of each smart water meter 1-1~1-16.

Please refer to FIG. 3B , which is a schematic diagram of the signal transmission method of the second embodiment of the smart water meter system of the present invention, and refer to FIGS. 1-3A for complex cooperation. The difference between this embodiment and the first embodiment shown in FIG. 3A is that in the first embodiment, the old smart water meter 1-1A as the main transmission water meter happened to fail (indicated by a dotted frame), and has not been replaced by a new smart water meter. 1-1B. Similarly, each smart water meter 1-2~1-16 measures the fluid data If and hardware data Ih of the self-water supply pipeline A to integrate them into water meter data Iw, and generates a weight parameter Pw according to the water meter data Iw . Then, the smart water meters 1-2~1-16 communicate with the adjacent smart water meters 1-2~1-16, so that the adjacent smart water meters 1-2~1-16 know the weight parameters Pw of each other, And select the master transmission water meter and the slave transmission water meter. In this embodiment, since the weight parameter Pw of smart water meters 1-5 is better, smart water meters 1-2~1-16 recommend smart water meters 1-5 as the main transmission water meter, and smart water meters 1-2~1-16 recommend smart water meters 1-5 as the main transmission water meter, and smart water meters 1-2~1-16 1-4, 1-6~1-16 are slave transmission water meters.

Then, the smart water meters 1-2 to 1-16 establish a transmission connection by connecting with one of the adjacent ones according to the weight parameter Pw. Since the transmission line system changes according to the weight parameter Pw, and the weight parameter Pw will change due to the environmental factors or working factors of the smart water meters 1-2~1-16, so Figure 3B The transmission connection of is different from the connection relationship of FIG. 3A. Then, according to the line of the transmission connection, the slave transmission water meter transmits its own water meter data Iw to the slave transmission water meter of the connection, and transmits it to the main transmission water meter at the end according to the connection relationship (that is, the smart water meter 1-5 ). Finally, the smart water meter 1-5 integrates the water meter data Iw of each slave transmission water meter and the water meter data Iw to which it belongs to the total area data Is, and transmits the total area data Is to the regional base station 200, so that the regional base station 200 can obtain Know the usage status of each smart water meter 1-2~1-16.

Please refer to FIG. 3C , which is a schematic diagram of the signal transmission mode of the third embodiment of the smart water meter system of the present invention, and refer to FIGS. 1-3B for complex cooperation. The difference between this embodiment and the first embodiment shown in FIG. 3B is that the old smart water meter 1-1A has been replaced by a new smart water meter 1-1B. After the smart water meter 1-1A is replaced with the smart water meter 1-1B, the smart water meter 1-1B receives the water meter data Iw of the old water meter stored in the memory module 16 of the smart water meter 1-2 through the transmission connection, namely The previous data of the old smart water meter 1-1A can be inherited (the reason is that in Fig. 3A, the smart water meter 1-1A as the main transmission water meter transmits the water meter data Iw to the smart water meter 1-2 as the slave transmission water meter ). Thereafter, the operation steps are the same as those shown in FIG. 3A , and will not be repeated here. It is worth mentioning that in one embodiment of the present invention, the sequence of the processes and steps in FIGS. 3A-3C above can be fine-tuned according to actual needs, and is not limited to the sequence in FIGS. 3A-3C .
