Description

Technical Field

[0002] At present, the development of domestic electric meters has gone through four stages. The first stage: mechanical electric energy meter. The electric meter is connected to the cable. When current passes through the electric meter, it will work on the induction wheel, causing the wheel to rotate. The greater the current, the greater the power, and the faster the wheel rotates, so that the power consumption of the load can be recorded. Although mechanical electric meters can record electric energy, the accuracy level is very low, the error is large, and the error will become larger and larger as the electric meter ages. The second stage: ordinary electronic electric energy meter. The electric meter has an MCU. After the voltage and current are sampled, a digital signal is output to the MCU through a special metering chip. The MCU collects and analyzes these data to form data such as electric energy and power. The data is transmitted to the LCD display through the display interface. Some also have buttons or 485 communication interfaces, the purpose of which is to better interact with people. The third stage: multi-function electric meter. Multifunctional electric meters use high-precision metering chips and multi-resource MCUs, which can quickly measure data including voltage, current, power, frequency, electric energy, etc., and can identify the positive and negative directions of electric energy, the angle between voltages, etc. Many metering chips have harmonic metering functions, and the main chip also has more resources to participate in the calculation. The fourth stage: Internet of Things electric meters. The application of IOT in the field of electric meters is mainly reflected in the introduction of multiple communication methods, including wired 485, MBUS, RJ45, wireless Lora, Wifi, Bluetooth, NB-IoT, 4G, etc. The electric meter needs to have a wired communication plus a wireless communication. As far as the Internet of Things electric meters are concerned, there are still the following problems: most smart electric meters are integrated structures, which can only be replaced as a whole when used, and the production cost and maintenance cost are high. Although smart electric meters have wireless communication functions, their wireless communication is single.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] It should be noted that the descriptions of "first", "second", etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0039] Most of the related smart meters are integrated structures, which can only be replaced as a whole when in use, and the production and maintenance costs are high. Although the smart meter has a wireless communication function, its wireless communication is single. In actual applications, various wireless communication technologies vary greatly in frequency bands, power modes, power consumption, cascade modes, etc. Before determining which communication method to use, it is necessary to fully understand the on-site environment. For this reason, this scheme proposes a combined adaptive smart meter, which aims to realize the modular assembly of smart meters, improve assembly efficiency, and reduce production and maintenance costs; and it has a variety of wireless communication functions to meet the needs of different on-site environments. Please refer to the following embodiments for the specific steps of the combined adaptive smart meter.

[0040] Please refer to Figure 1 , Figure 1The structure diagram of a combined adaptive smart meter according to an embodiment of the present invention is shown in FIG. In the embodiment of the present invention, the combined adaptive smart meter includes a base meter 100, a sampling module 200, a key and display module 400, and a multifunctional wireless communication module 300. The base meter 100 is electrically connected to the sampling module 200, the key and display module 400, and the multifunctional wireless communication module 300 respectively; the base meter 100 has a first jack 120, a second jack 110, and a third jack; the sampling module 200 has a first pin 210, and the first pin 210 is electrically connected to the third pin 120 ... A socket 120 is plugged in and matched to enable the base meter 100 and the sampling module 200 to be hot-pluggable; the multifunctional wireless communication module 300 has a second pin 310, which is plugged in and matched with the second socket 110 to enable the base meter 100 and the multifunctional wireless communication module 300 to be hot-pluggable; the button and display module 400 has a third pin 410, which is plugged in and matched with the third socket to enable the base meter 100 and the button and display module 400 to be hot-pluggable.

[0041] In this embodiment, the combined adaptive smart meter adopts modular assembly of the sampling module 200, the button and display module 400, and the multifunctional wireless communication module 300 with the base meter 100. The base meter 100 can work independently, and the sampling module 200, the button and display module 400, and the multifunctional wireless communication module 300 can be disassembled independently, which is very convenient for installation and maintenance. In addition, the sampling module 200, the button and display module 400, and the multifunctional wireless communication module 300 are hot-swappable with the base meter 100 by means of pins and sockets, which is easy to operate and the electrical connection is more stable. The sampling module 200 is separated from the base meter 100 to physically separate the strong current and the weak current. When the external current is large, the transformer access module can be selected. When the external current is small, the direct access sampling module 200 can be used. It is also possible to select different power supply modes of three-phase three-wire or three-phase four-wire. The number of the first jack 120, the second jack 110, and the third jack can be set according to actual requirements, and there is no restriction here.

[0042] In some embodiments, in order to ensure the reliability of the connection, in the above-mentioned structure of the pin and the socket, the socket part is further provided with a bayonet, and the pin part is provided with a protrusion. Specifically, when the pin is inserted into the socket to a set depth, the protrusion of the pin sinks into the bayonet. At this time, the pin and the socket are stably connected to ensure the reliability of the connection. In addition, the pin can also be bent. When the pin is inserted into the socket to a preset depth, the bent part of the pin abuts the socket. At this time, the pin and the socket are stably connected to avoid continuing to insert the pin and damaging the pin.

[0043] In some embodiments, the base meter 100 can also be hot-swapped with at least one of the sampling module 200, the button and display module 400, and the multi-functional wireless communication module 300, so that the cost of the smart meter can be reduced, the volume of the smart meter can be reduced, and the miniaturization design of the smart meter can be facilitated. For example, the meter used in the charging pile only needs a button and display module 400 and the base meter 100.

[0044] In some embodiments, the pins and sockets can be replaced with corresponding male and female connectors to increase service life and make the connection more stable.

[0045] In one embodiment, the multifunctional wireless communication module 300 is any one of a Lora communication module, a Wifi communication module, a Bluetooth communication module, a NB-IoT communication module and a 4G communication module, and the second jack 110 includes a 0-end interface, a Lora communication interface, a Wifi communication interface, a Bluetooth communication interface, a NB-IoT communication interface and a 4G communication interface;

[0046] The O-end interface is combined with the Lora communication interface to identify the Lora communication module; the O-end interface is combined with the Wifi communication interface to identify the Wifi communication module; the O-end interface is combined with the Bluetooth communication interface to identify the Bluetooth communication module; the O-end interface is combined with the NB-IoT communication interface to identify the NB-IoT communication module; the O-end interface is combined with the 4G communication interface to identify the 4G communication module.

[0047] In this embodiment, the 0-end interface is a square hole 111, and the remaining interfaces are round holes 112. The second jack 110 includes 2 square holes 111 and 10 round holes 112, among which the 0-end interface is specifically a 485 communication interface, 1 is a Lora communication interface; 2 is a Wifi communication interface; 3 is a Bluetooth communication interface; 4 is a NB-IoT communication interface; 5 is a 4G communication interface. 485 communication is used between the base meter 100 and various wireless communication modules. 485 communication uses high-speed optical coupling, which is used for isolation on the one hand and to ensure high-speed communication rate, which is stable at more than 57600bps on the other hand. Taking into account the stability of the connection, in this embodiment, the square holes 111 and the round holes 112 are arranged in double rows. It should be noted that all multifunctional wireless communication modules 300 must have a 0-end interface, but one of the ports will appear at the 1, 2, 3, 4, and 5 ends depending on the specific module. Please refer to Figures 2 to 6 , Figure 2-Figure 6The following is a schematic diagram of the combination of the base meter 100 of an embodiment of the present invention with the Lora communication module, Wifi communication module, Bluetooth communication module, NB-IoT communication module and 4G communication module. As can be seen from the above figure, the Lora communication interface is terminal 0 and terminal 1; the Wifi communication interface is terminal 0 and terminal 2; the Bluetooth communication interface is terminal 0 and terminal 3; the NB-IoT communication interface is terminal 0 and terminal 4; and the 4G communication interface is terminal 0 and terminal 5. The base meter 100 can realize multi-channel power supply. Because the voltage, current and power of each module are different, there are higher requirements for the external power supply of the base meter 100, and 5 stable different power supplies are required. For example, the voltage of the Lora communication module is 3.3V, the peak current is 150mA, the voltage of the Wifi communication module is 3.3V, the peak current is 500mA, the voltage of the Bluetooth communication module is 3.3V, the peak current is 20mA, the voltage of the NB-IoT communication module is 3.8V, the peak current is 500mA, and the voltage of the 4G communication module is 3.8V, the peak current is 2-3A.

[0048] In some embodiments, the first pin 210 of the sampling module 200 and the third pin 410 of the button and display module 400 each have at least one identification pin, and the first jack 120 and the third jack of the base meter 100 each have at least one identification port. For the button and display module 400, the base meter 100 is used for power supply. The base meter 100 MCU has its own LCD driver, so it only needs to match the pins. The identification of the button and display module is mainly determined by the connection wires 30 and 31, and the judgment truth table is shown in Table 1.

[0051] In the program flow, the four states are judged one by one from top to bottom to determine the specific type of the key and display module 400. For the sampling module 200, the sampling module 200 is judged according to the No. 1 and No. 0 terminals of the sampling module 200, as shown in Table 2.

[0052] Table 2

[0053]

[0054] In some embodiments, the first jack 120, the second jack 110 and the third jack of the base meter 100 are respectively provided with baffles, and the baffles are respectively isolated from the first jack 120, the second jack 110 and the third jack. The baffles can prevent water from entering the base meter 100, ensuring that the smart meter can meet the protection requirements of IP54. It can be understood that the baffles can also be replaced by rubber pads, and the rubber pads are provided with plugs for the jacks to penetrate at the corresponding jacks, which can be waterproof and fall off when the pin is inserted. The plug can also be replaced by a soft part, which can be separated when the pin is inserted and closed when the pin is withdrawn.

[0055] The base table 100 is provided with an installation slot 130 for installing any one of the sampling module 200, the multifunctional wireless communication module 300 and the key and display module 400, and the first plug hole 120 of the sampling module 200, the second plug hole 110 of the multifunctional wireless communication module 300 or the third plug hole of the key and display module 400 are arranged on the slot wall of the installation slot 130. The installation slot 130 also has a limiting effect on the sampling module 200, the multifunctional wireless communication module 300 and the key and display module 400, which facilitates the installation of each module and can improve the stability of the connection.

[0056] In summary, the smart meter has at least the following effects:

[0057] 1. It can be operated after the base meter 100 and the sampling module 200 cooperate with each other, and no external modules are needed to form a minimized system.

[0058] 2. The sampling module 200 can be removed separately during maintenance. After the sampling module 200 is removed, the voltage of the base meter 100 or other modules will not exceed DC24V, ensuring that the base meter 100 and other modules are in a weak current state, which is convenient for maintenance and maintenance.

[0059] 3. If the customer wants to update the buttons, display module and wireless communication module after running for a period of time, it is easy to replace due to hot-swap support. Considering this aspect alone, a lot of costs can be saved, including disassembly costs, installation costs, hardware and transportation costs of the meter itself, debugging costs, etc., and the comprehensive calculation can save more than 60% of the costs.

[0060] 4. Since the protocol part and module identification program have been integrated into the basic and corresponding modules, the debugging work is greatly reduced, which can reduce 80% of the debugging workload.

[0061] 5. The basic and sampling parts can be used separately for charging piles, and the photovoltaic and other industries can save more than 40% of the meter hardware cost.

[0062] Please refer to Figure 7 , Figure 7The flowchart of the module automatic identification method of the combined adaptive smart meter according to an embodiment of the present invention. In the embodiment of the present invention, the module automatic identification method of the combined adaptive smart meter comprises the following steps:

[0063] S100, when an access module is detected to be inserted, obtaining coding information of the access module, wherein the access module includes any one of a sampling module, a key and display module, and a multifunctional wireless communication module;

[0064] S200, identifying the access module type according to the coding information of the access module; and

[0065] S300. Configure corresponding access module parameters according to the access module type and perform access processing. When the access module is a sampling module, configure the sampling module parameters and perform signal sampling processing; when the access module is a multi-functional wireless communication module, configure the multi-functional wireless communication module parameters and perform wireless communication processing; when the access module is a button and display module, configure the sampling module parameters and perform button and display processing.

[0066] Specifically, when the base meter of the smart meter is running, it will monitor whether there is an access module inserted. When the access module is detected to be inserted, the coding information of the access module is obtained. The coding information corresponds to the characteristic bits of each type of module, and the type of access module can be identified according to the characteristic bits. Then, the corresponding access module parameters are configured according to the access module type and the access processing is performed. In this way, the types of various modules currently matched can be realized and the matching and program running can be started automatically.

[0067] Please refer to Figure 8 , Figure 8 This is a flow chart of a module automatic identification method of a combined adaptive smart meter according to another embodiment of the present invention. Specifically, the sample module, the key and display module, and the multifunctional wireless communication module all have identification pins, and the identification pins form a characteristic code;

[0068] The configuring corresponding access module parameters according to the access module type and performing access processing also includes:

[0069] S310, configuring access module parameters according to the access module type and determining a feature code of the access module;

[0070] S330, executing access processing according to the feature code of the access module, and automatically identifying success.

[0071] In this embodiment, the identification pin can be coded with 0 or 1. If there are four types of access modules, 00, 01, 10, and 11 can represent the four specific access modules respectively. When there are more than four types of access modules, the coding position can be expanded. By determining the feature code, the specific type of the access module can be further determined to facilitate identification processing.

[0072] Please continue to refer to Figure 8 Specifically, the determining the feature code of the access module according to the access module type further includes:

[0073] S320, obtaining and determining whether the number of times of the feature code of the access module reaches the identification number threshold;

[0074] S330: When the number of times of obtaining the characteristic code for determining the access module reaches the identification number threshold, the characteristic code of the access module is determined according to the type of the access module, and the automatic identification is successful.

[0075] When the number of times the characteristic code for determining the access module is obtained is less than the identification number threshold, the automatic identification fails. In this case, manual matching is required, or the corresponding access module is replaced.

[0076] Specifically, configuring access module parameters according to the access module type and determining the feature code of the access module also includes:

[0077] Run the access module according to the parameters of the configured access module;

[0078] Determine whether the operation time of the access module reaches a threshold time;

[0079] When the operation time of the access module reaches a threshold time, a feature code of the access module is determined.

[0080] By setting the threshold duration, the smart meter can be guaranteed to work stably when connected to the access module, which facilitates the subsequent automatic identification of the access module.

[0081] It can be understood that when automatically identifying the access module, this embodiment adopts automatic identification of the access modules one by one. When there are multiple access modules, multiple access modules can also be identified in parallel according to the setting of the base table to improve the identification efficiency.
