[0025] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] An embodiment of the present invention discloses a data acquisition method, which is applied to a power acquisition terminal integrated with multiple processes. The power acquisition terminal is communicatively connected to a carrier module through a USB interface and maps out multiple virtual serial ports. Specifically, the USB-CDC protocol can be used for USB protocol enumeration negotiation to map out multiple virtual serial ports. The carrier module is integrated with a communication module for communicating with external sensors. At least one of the multiple virtual serial ports is used for performing sensor identity confirmation with the carrier module, and at least one is used for receiving power data uploaded by the carrier module. In the embodiment of the present application, one of the mapped multiple virtual serial ports can be selected to communicate with the carrier module for sensor identity confirmation, and one virtual serial port is specifically used for receiving power data uploaded by the carrier module. Those skilled in the art can also select multiple virtual serial ports to receive power data respectively as needed, as long as it is ensured that the virtual serial port for receiving power data is only used for receiving power data. The power acquisition terminal in the embodiment of the present application is a power acquisition terminal obtained by fusing an energy controller terminal and a marketing intelligent terminal, and sufficient storage space and memory can be configured for the power acquisition terminal to support the software design of multiple processes. The power acquisition terminal can map out multiple virtual serial ports by communicatively connecting to the carrier module through a USB interface, with high scalability and capable of supporting the above-mentioned multiple-process services. As Figure 1 shown, the method includes the following steps:

[0027] Step 101, when the virtual serial port for performing sensor identity confirmation receives the sensor attribute data uploaded by the carrier module, determine the type of the sensor for the data to be uploaded according to the sensor attribute data. Exemplarily, in the embodiment of the present application, the carrier module is communicatively connected to the sensor that needs to perform data transmission. The carrier module can send an identity attribute data acquisition instruction to the sensor with which the communication connection is established, and then the carrier module can transmit the identity attribute data fed back by the sensor to the power acquisition terminal through the virtual serial port for performing sensor identity confirmation. The power acquisition terminal can listen to the virtual serial port channel to implement the negotiation operation of sensor identity with the carrier module, and determine the type of the sensor according to the acquired sensor data.

[0028] Step 102, based on the remaining virtual serial ports among the mapped multiple virtual serial ports, configure one virtual serial port and the process corresponding to the virtual serial port for each type of sensor. The remaining virtual serial ports are the remaining virtual serial ports except for the virtual serial port used for performing sensor identity confirmation with the carrier module and the virtual serial port for receiving the power data uploaded by the carrier module.

[0029] Exemplarily, in the embodiment of the present application, the power acquisition terminal can map out multiple virtual serial ports on the power acquisition terminal by communicatively connecting to the carrier module through a USB interface, as Figure 2As shown in the figure, define tty1, tty2... ttyN as the corresponding virtual serial ports of the mapping. Among them, at least one virtual serial port is used to transmit the sensor identity attribute information data, so as to confirm the type of the sensor. As the main collection service of the power collection terminal, at least one virtual serial port is used to receive the power data uploaded by the carrier module based on the standard communication protocol of the power user information collection system. The remaining virtual serial ports are used to transmit the sensor data. Specifically, the configuration process of the virtual serial port for receiving sensor data needs to be determined in combination with the type of the sensor to be uploaded (such as function type, protocol type). The power collection terminal negotiates with the carrier module for the sensor identity to determine the sensor type, and matches each type of sensor with the remaining virtual serial ports to determine the virtual serial port for receiving the sensor data of the corresponding type. At the same time, the channel function code corresponding to each virtual serial port is obtained. The channel function code is used to confirm which sensor the virtual serial port is connected to for data transmission. At the same time, the power collection terminal can configure the process matching each type of sensor according to its function type. A soft connection is formed between different processes and the corresponding virtual serial ports to form a data transmission channel, and the corresponding virtual serial port is accessed to realize data interaction with the sensor.

[0030] In a specific embodiment, as Figure 2 shown in the figure, the virtual serial port 1 is pre-configured to transmit the sensor identity attribute information data. The carrier module transmits the power data to the power collection terminal through the virtual serial port 2. The carrier module is connected to the temperature and humidity sensor, vibration sensor or other types of sensors (xxx sensors); taking the temperature and humidity sensor as an example, the carrier module transmits the identity attribute data of the temperature and humidity sensor to the power collection terminal through the virtual serial port 1. The power collection terminal determines the type of the temperature and humidity sensor (such as function type, protocol type, etc.), and confirms that the function code of the virtual serial port 3 is for temperature and humidity sensor data collection. The power collection terminal configures the temperature and humidity collection process. The temperature and humidity collection process identifies the virtual serial port 3 as the corresponding sensor data transmission channel, and communicates with the sensor and collects the sensor data based on the protocol followed by the temperature and humidity sensor.

[0031] Step 103: Send a communication request to the carrier module, so that the carrier module performs sensor data collection and transmission based on the communication request;

[0032] Exemplarily, in the embodiment of the present application, after the power collection terminal deploys the collection process of the corresponding sensor, the collection process identifies the virtual serial port corresponding to the corresponding sensor and sends a communication request to the carrier module, where the communication request at least includes a data collection request, etc. The carrier module performs sensor data collection and transmits the collected data to the corresponding process of the power collection terminal. In a specific embodiment, as Figure 2As shown, after the temperature and humidity acquisition process identifies virtual serial port 3 as the corresponding sensor data transmission channel, the temperature and humidity acquisition process sends a data acquisition request to the carrier module through virtual serial port 3. After the carrier module acquires the data of the temperature and humidity sensor, it transmits the temperature and humidity data to the temperature and humidity acquisition process through virtual serial port 3, only for example.

[0033] Step 104, when receiving the data uploaded by any virtual serial port, perform data acquisition based on the process corresponding to the virtual serial port.

[0034] Exemplarily, the data uploaded by any virtual serial port received can be power data or sensor data. Since the virtual serial ports and processes for receiving the corresponding type of data have been configured, the carrier module can transmit the data to the corresponding sensor acquisition process in the power acquisition terminal through the corresponding virtual serial port and perform the meter reading operation. This acquisition process can perform data acquisition and storage; after the carrier module transmits the temperature and humidity data to the temperature and humidity acquisition process through the corresponding sensor virtual serial port, the temperature and humidity acquisition process performs the acquisition and storage of the temperature and humidity data.

[0035] For the data acquisition method provided by the present invention, when the virtual serial port preconfigured for sensor identity confirmation receives the sensor attribute data uploaded by the carrier module, determine the type of the sensor, and based on the remaining virtual serial ports in the mapped multiple virtual serial ports, configure one virtual serial port and the process corresponding to the virtual serial port for each type of sensor, and send a communication request to the carrier module to enable the carrier module to perform the acquisition and transmission of sensor data. When receiving the data uploaded by any virtual serial port, perform data acquisition based on the data corresponding to the virtual serial port; the present invention configures different virtual serial ports to receive power data and sensor data, and can support the development of multiple services for other types of data while not affecting the main power data acquisition.

[0036] As an optional implementation manner of the present invention, the carrier module is connected to an external sensor through a wireless communication module. Exemplarily, as Figure 2 shown, in the embodiment of the present application, the carrier module is connected to an external sensor through adding a built-in Bluetooth or Zigbee and other common Internet of Things to acquire sensor data, which can reduce the wiring cost and cumbersome workload brought by wired communication. Taking Bluetooth communication as an example, Bluetooth broadcast can be sent after the power acquisition terminal is powered on to obtain the sensor data in the corresponding service scenario.

[0037] As an optional implementation manner of the present invention, different virtual serial ports correspond to different processes.

[0038] Exemplarily, in the embodiments of the present application, after the power collection terminal maps out multiple virtual serial ports, different processes are configured for different virtual serial ports, and each process is independent and does not affect each other. In a specific embodiment, as Figure 2 shown, the power collection terminal configures a main process for the virtual serial port 1. The main process determines the type of the sensor according to the transmitted sensor identity attribute information through the virtual serial port 1 and matches it with the remaining virtual serial ports; the power collection terminal configures a collection scheduling process for the virtual serial port 2. The collection process determines whether the power data transmission channel corresponding to the power service exists and receives the power data uploaded by the carrier module through the virtual serial port 2. This collection method increases the stability of the power data; the power collection terminal configures a temperature and humidity collection process for the virtual serial port 3. The temperature and humidity collection process sends a data collection request to the carrier module through the virtual serial port 3 and stores and records the data when the temperature and humidity data is received; in the power collection terminal of the present invention, different collection processes are deployed according to the types and protocols of different sensors, which does not affect the operation of the main process and the collection scheduling process, and increases the stability of the main collection services of the power collection terminal.

[0039] As an optional implementation manner of the present invention, the method further includes: when receiving the sensor data uploaded by any virtual serial port, using the corresponding process to collect and record the sensor data; summarizing the sensor data recorded by each process. Exemplarily, the collection processes corresponding to different sensors can store and record the sensor data according to common data formats such as json and XML, and the main process summarizes and reports the data according to the data record.

[0040] As an optional implementation manner of the present invention, a USB2.0 interface is used for communication between the power collection terminal and the carrier module. Exemplarily, in the embodiments of the present application, a USB2.0 interface is used between the carrier module and the power collection terminal, so that communication can be carried out based on a rate of 480Mhz, ensuring the support for the transmission of large amounts of data.

[0041] The embodiments of the present application also disclose a data collection system, as Figure 3 shown, the system includes: a carrier module for accessing external sensor data; a power collection terminal communicating with the carrier module through a USB interface for executing the data collection method described in the above embodiments.

By configuring different virtual serial ports to receive power data and sensor data, the present invention can support the development of multiple services for other types of data while not affecting the main power data acquisition.
