The meter box terminal 40 may be, but not limited to, an electric energy meter for collecting electricity consumption, an electronic water meter for collecting water consumption, and an electronic gas meter for collecting gas consumption.

Understandably, the meter box terminal 40 can be one of the component devices in the data acquisition system 10 (the other component devices in the data acquisition system 10 can be the concentrator 20 and the master station device 30 ), or can be independent of the data acquisition system. The system 10 is not a device belonging to the data acquisition system 10 .

The main station device 30 may be, but is not limited to, a personal computer (Personal Computer, PC), a personal digital assistant (Personal Digital Assistant, PDA), a mobile Internet device (Mobile Internet Device, MID), a server, and the like.

Referring to FIG. 2 , an embodiment of the present application further provides a concentrator 20 . The concentrator 20 may include a first communication module 21, a second communication module 22, and a processing module 23. The components of the first communication module 21, the second communication module 22, and the processing module 23 are directly or indirectly electrically connected to achieve The transfer or interaction of data. For example, these elements may be electrically connected to each other through one or more communication buses or signal lines.

The processing module 23 may be an integrated circuit chip, which has signal processing capability. The above-mentioned processing module 23 may be a general-purpose processor. For example, the processor may be a microprocessor, a central processing unit (Central Processing Unit, CPU), a network processor (Network Processor, NP), etc.; it may also be a digital signal processor (Digital Signal Processing, DSP), an application-specific integrated circuit ( Application Specific Integrated Circuit, ASIC), Field-Programmable Gate Array (Field-Programmable Gate Array, FPGA), or other programmable logic devices, discrete gate or transistor logic devices, and discrete hardware components, can implement or execute the embodiments of the present application. The disclosed methods, steps and logical block diagrams.

For example, the processing module 23 can be a SAM9X25 chip, which has two USB ports 25 and two Ethernet ports (physical network ports 24 ), which can satisfy the connection with the first communication module 21 and the second communication module 22 .

The first communication module 21 may be, but is not limited to, a 4G communication module, a 5G communication module, etc., and is used to establish a communication connection between the concentrator 20 and the master station device 30 through a wireless network for data interaction. The second communication module 22 may be an HPLC (High-Speed Power line Communication, high-speed power carrier) module for establishing a communication connection between the concentrator 20 and the meter box terminal 40 through a network, and sending and receiving data through the network.

The concentrator 20 may also include a storage module connected to the processing module 23 . Understandably, the storage module can be integrated into the processing module 23, so that the processing module 23 has the function of storing data. Alternatively, the storage module is a separate device from the processing module 23 .

The memory module can be, but is not limited to, random access memory, read only memory, programmable read only memory, erasable programmable read only memory, electrically erasable programmable read only memory, Flash (flash) memory, and the like. In this embodiment, the storage module may be used to store the data collected from the meter box terminal 40 . For example, if the meter box terminal 40 is an electric energy meter, the storage module can store the electricity consumption recorded by the electric energy meter obtained by the concentrator 20 from the electric energy meter. Of course, the storage module can also be used to store a program, and the processing module 23 executes the program after receiving the execution instruction.

In this embodiment, a firmware program may be stored in the storage module of the concentrator 20 . The first communication module 21 can be connected to the processing module 23 through the USB port 25 . For example, the 4G communication module can be connected with the microprocessor through the USB port 25, and through the firmware, the communication connection between the concentrator 20 and the main station device 30 can be established through the 4G communication module. When the connection is successful, the concentrator 20 can obtain the application program from the fixed path of the main station device 30 through the NFS (Network File System, network file system) communication protocol, and then run the application program.

Since the signal connection between the processing module 23 and the first communication module 21 is realized through the USB port 25, compared with the connection mode of the physical serial port, the connection between the processing module 23 and the first communication module 21 is realized through the USB port 25 (that is, establishing a USB port 25). high-speed data channel), which can increase the maximum bandwidth of data transmission between the processing module 23 and the first communication module 21, thereby helping to improve the network speed of data transmission between the concentrator 20 and the main station device 30. When the concentrator 20 obtains the application program from the main station device 30, the application program can be downloaded quickly.

The second communication module 22 (such as the HPLC module) can be connected to the processing module 23 through the physical network port 24. When the second communication module 22 operates, the concentrator 20 operates in the server mode, and the second communication module 22 operates in the client mode. , the second communication module 22 can actively establish a Socket (socket) connection with the concentrator 20, and use the TCP/IP (Transmission Control Protocol/Internet Protocol, Transmission Control Protocol/Internet Protocol) protocol to communicate.

When the concentrator 20 is powered on, the first communication module (such as a 4G communication module) block starts to run. When the first communication module 21 is running, the concentrator 20 can automatically identify the virtual network port (such as the CDC_ECM virtual network port) under the USB port 25, and then the concentrator 20 establishes a socket connection with the host device 30 in the client mode, using TCP/IP protocol for communication.

Since the second communication module 22 is connected to the processing module 23 through the physical network port 24, compared with the physical serial port, the connection method of the physical network port 24 can increase the maximum bandwidth of data transmission between the processing module 23 and the second communication module 22, Therefore, it is helpful to improve the network speed of data transmission between the concentrator 20 and the meter box terminal 40 .

Understandably, the communication rate of the application layer of the HPLC module can reach 3Mbit/s, and the communication rate of the 4G communication module can reach 13Mbps. The applicant found that the communication rate of the existing physical serial port is only 115200bps≈112.5Kbit/s. Therefore, the connection method of the physical serial port will become a bottleneck for improving the rate of the concentrator 20, which restricts the concentrator 20, the main station device 30 and the meter box terminal. 40 overall communication rate. In the present application, by using the physical network port 24 and the USB port 25, the overall communication rate between the concentrator 20, the master station device 30 and the meter box terminal 40 can be improved.

It can be understood that the structure shown in FIG. 2 is only a schematic structural diagram of the concentrator 20 , and the concentrator 20 may also include more or less components than those shown in FIG. 2 . The components shown in FIG. 2 can be implemented in hardware, software, or a combination thereof.

Referring to FIG. 3 , an embodiment of the present application provides a data acquisition method, which can be applied to the above-mentioned concentrator 20 , and can be executed or implemented by the concentrator 20 in various steps of the method. In this embodiment, the data acquisition method may include the following steps:

Step S120, obtaining a current application program from the main station device 30 communicatively connected to the concentrator 20, and the current application program is used to drive the concentrator 20 to collect specified data;

Step S130, running the current application program to acquire specified data through the current application program.

In the above-mentioned embodiment, when the concentrator 20 is running, it obtains the application program from the main station device 30, which helps the concentrator 20 to directly obtain the updated application program from the main station device 30, and improves the application program update of the concentrator 20. problem of low efficiency.

Each step of the method shown in Figure 3 will be described in detail below:

Step S120: Acquire a current application program from the master station device 30 that is communicatively connected to the concentrator 20, where the current application program is used to drive the concentrator 20 to collect specified data.

In this embodiment, the application program of the concentrator 20 stored in the master station device 30 may be the latest version of the application program. Of course, other versions of application programs of the concentrator 20 may also be stored in the master station device 30 . If the application program of the latest version of the concentrator 20 is not stored in the main station device 30, the administrator can enter the application program of the latest version into the main station device 30, so that the application program of each concentrator 20 can be easily processed by the main station device 30. to update.

When the concentrator 20 acquires the application from the master device 30 , the master device 30 may compare the version of the application that was last used by the concentrator 20 with the version of the application currently stored by the master device 30 . If the version of the last used application (may be referred to as the first version) is smaller than the version of the application currently stored in the master device 30 (the second version), it means that the first version is older than the second version. At this time, the master station device 30 may send the application program of the second version to the concentrator 20 to update the application program of the concentrator 20 .

If the version of the first version is the same as the version of the second version, the master station device 30 can continue to send the application program of the second version to the concentrator 20, so that the concentrator 20 can obtain the application program, so that the concentrator 20 can pass the obtained application program. application to collect the specified data recorded by the meter box terminal 40 . The specified data can be set according to the actual situation. For example, the specified data includes but is not limited to data such as electricity consumption of an electric energy meter, water consumption of an electronic water meter, and gas consumption of an electronic gas meter.

Understandably, the current application program acquired by the concentrator 20 is usually the latest version of the application program in the master station device 30 for driving the concentrator 20 to collect the specified data, so that the concentrator 20 can use the latest version of the application program in time. to collect the data recorded by the meter box terminal 40. The new version of the application is usually a program that fixes some bugs in the old version of the application, or is updated with new functions. Therefore, based on this, it is possible to improve the problem of security risks in data collection caused by loopholes in the old version of the application program, or to increase the function of the concentrator 20 . The newly added function can be determined according to the newly added function of the updated application program, and the function can be set according to the actual situation (for example, changing the duration of uploading data from the concentrator 20 to the main station device 30 ), which is not specifically limited here.

In this embodiment, step S120 may include: when the concentrator 20 is powered on, identifying the designated virtual network port of the first communication module 21 connected to the concentrator 20; The virtual network port establishes the communication connection with the main station device 30 ; obtains the current application program from the main station device 30 .

For example, the first communication module 21 is a 4G communication module (of course, the first communication module 21 can also be other high-speed communication modules used for long-distance communication, such as a 5G communication module), and the processing module 23 can identify the specified connection with the 4G communication module. Virtual network port (this virtual network port can be set according to the actual situation, such as the CDC_ECM virtual network port, which is not limited here); then, the concentrator 20 communicates with the master station device through the designated virtual network port in client mode 30 Establish a Socket connection. After the connection is established, the concentrator 20 can obtain the latest version of the application program of the concentrator 20 from the fixed path of the main station device 30 through the 4G communication module and the NFS communication protocol, and the obtained application program is the application program of the concentrator 20 current application.

Based on this, when the application program of the concentrator 20 needs to be upgraded, the program can be updated by replacing the application program in the master station device 30 , thereby helping to simplify the operation steps of updating the program of the concentrator 20 . In addition, since the 4G communication module is connected to the processing module 23 through the USB port 25, it is helpful to improve the maximum network speed of the communication between the concentrator 20 and the master station device 30, thereby improving the efficiency of program update and shortening the transmission time of the application program.

Step S130, running the current application program to acquire specified data through the current application program.

In this embodiment, the current application program can be created according to the actual situation, for example, it can be set by the developer according to the data requirements of the terminal 40 of the collection table box. After the concentrator 20 obtains the current application program, it can collect data recorded by one or more meter box terminals 40 connected to the concentrator 20 in cooperation with the existing firmware program of the concentrator 20 to realize centralized meter reading of the data.

As an optional implementation manner, the method may further include: sending the specified data acquired within the preset time period to the master station device 30 every preset time period.

In this embodiment, the preset duration (which may be referred to as the first preset duration) may be set according to actual conditions, and may be 1 hour, 24 hours, one week, one month, etc. The preset duration is not specifically limited here. After the concentrator 20 collects the data, it can send the collected data to the master station device 30 every preset time period (for example, 1 hour, 24 hours, one week, one month, etc.). After sending the data to the main station device 30 , the concentrator 20 may delete the data in the cache to free up storage space for the cache, so as to cache new data collected from the meter box terminal 40 .

As an optional implementation manner, the method may further include: the concentrator 20 may set an interval of a certain period of time (this period of time may be referred to as a second preset period of time, which may be set according to the actual situation, for example, it may be 24 hours, one month Equal time) collects data from the meter box terminal 40, and after collecting the data, the concentrator 20 can directly send the collected data to the terminal device. Based on this, the concentrator 20 does not need to provide a storage module with a larger storage capacity. Understandably, the hardware cost of a storage module with a larger capacity (eg, greater than 64MB) is generally higher than that of a storage module with a small capacity (eg, less than 64MB), which helps to reduce the hardware fabrication cost of the concentrator 20 .

As an optional implementation manner, the method may further include: when the acquired total data capacity of the specified data is greater than or equal to a specified threshold, sending the specified data to the master station device 30 .

In this embodiment, the specified threshold can be continuously set according to the actual situation, for example, it can be 100KB, 1M and so on. When the total data capacity of the designated data collected by the concentrator 20 from the meter terminal 40 is greater than or equal to the designated threshold, the concentrator 20 can send all the total designated data collected so far to the main station device 30 .

After sending the data to the main station device 30, the concentrator 20 can delete the sent data locally, and then record the capacity of the new data collected from the meter box terminal 40. When the total amount of the collected new data is When the data capacity is greater than or equal to the specified threshold, all the collected data can be sent to the master station device 30 again, and the data can be collected and sent cyclically in this way, so that the concentrator 20 can continue (or long-term) from the meter box terminal 40. Collect data, and send the collected data to the master station device 30 .

As an optional embodiment, the method may further include: within a preset time period, judging whether the total data capacity of the specified data collected from the meter box terminal 40 is greater than or equal to a specified threshold; when the total data capacity is greater than or equal to a specified When the threshold value is reached, the designated data acquired up to now is sent to the master station device 30 . At this time, the concentrator 20 can re-time, and then continue to detect the newly collected data (designated data). Send it to the master station device 30; if the total data capacity of the collected data is less than the specified threshold within the preset time period after the retiming, then when the time period is the preset time period after the retiming, the collected specified data will be sent to Master device 30, and then re-time.

Of course, when the total data capacity is greater than or equal to the specified threshold, after the specified data obtained up to now is sent to the master station device 30, the concentrator 20 can also continue to time the time after the time of sending the data (that is, at this time No re-timing), and then continue to detect the newly collected data (excluding the data that has already been sent); within the preset time period, if the total data capacity of the collected new data is greater than or equal to the specified threshold, then Continue to send the newly collected data to the master station device 30 . When the time length is the preset time length, the time from the last data sent to the master station device 30 before the preset time length (the first time) to the time of the preset time length (the second time), the period (the first time to The designated data collected during the second time instant) is sent to the master station device 30 .

Referring to FIG. 4 , before step S120 , the method may further include a step of initializing the concentrator 20 . For example, before step S120, the method may further include step S110. Step S110: Initialize the concentrator 20 to delete the application program stored in the concentrator 20 in advance.

In this embodiment, when the concentrator 20 is powered on, the storage module can be initialized through a firmware program. Understandably, for the storage area used to store the application program in the storage module of the concentrator 20, during initialization, no matter whether the storage area stores the application program or not, in the process of initialization, the firmware program can be used to store the storage area. Data formatting to clear this storage area. Of course, if there is no application program in the storage area, the initialization operation may not be required; or, during initialization, the operation of formatting (or clearing) the storage area does not need to be performed.

Referring to FIG. 2 again, in the concentrator 20 provided in this embodiment of the present application, the first communication module 21 is configured to obtain the current application program from the master station device 30 communicatively connected to the concentrator 20 . The application program is used to drive the concentrator 20 to collect specified data.
