Referring to FIG. 1 , the system for constructing a distributed return of distributed energy-consuming equipment monitoring data by using a device control system message exchange mechanism provided by the present invention mainly includes:

A server-side mediation layer library 101 is configured to actively send settings, perform new device management functions, and passively receive data for data processing, storage, and utilization.

A device-side mediation layer library 102 is configured to passively receive settings, complete a new device management function, and actively send data to report the current status of the device to the system.

A library calls 103 (Request), sends the user's set value, and actively requests the underlying device to report the latest data.

A library responds to 104 (Response) and returns the read value of the device.

A Building Energy Management (BEMS) service software 111 for users Direct operation, contact system.

A device control system 112 interfaces with the underlying physical device to recover monitoring data.

In FIG. 1, the server-side media library 101 is embedded in the building energy management service software 111, and the device-side media library 102 is embedded in the device control system 112. The convergence completes the respective tasks, and calls 103 and the library response 104 through the library to complete the data collection.

For a detailed definition of the library call 103 and the library response 104, please refer to Figure 2, which will be described later. In the example of Figure 2, the data is transmitted based on the HTTP packet. The configuration of the data in the HTTP packet is:

An HTTP packet header (header 211) does not affect the method independently of each other.

An HTTP packet body 212 containing the CAC instruction set of the method.

An HTTP packet Multipart 213, which contains multiple formatted Formatted Device Values (FDVs) 223 data of the method.

A control action command header (CAC Header) 221, this part is a unified standard of several fields, respectively, control server number, message number, sender URL, receiver URL, message type and time stamp.

A control action instruction body (CAC Body) 222 type definition is wide In general, the CAC Body is the main spirit of the iEN-Box Message. The message category field summary describes different CAC Body contents. In particular, the equipment history and data records are necessary, as detailed below:

The device history: The message format defines the types of devices that can be supported, including Fatek (Yonghong Technology), Modbus, CQi (Vertical Technology) and other related control servers, controllers and devices. In the device history category, the main action is The building energy management service software 111 performs a requesting action on the control server, including a new management, cancellation management, or attribute change, as the building energy management service software 111 communicates with the control server to establish a management basis. In addition, for the abnormal situation, the message is used to record the error information (such as: ErrorInfo) to express the error message, so that when the error occurs in the process, the logic can be judged or the relevant record can be left to facilitate the management to handle the follow-up work.

The data record: the core content of the method, in the distributed energy-consuming device and its control server end, after the data is collected and processed by the control server, it is concentrated on the building energy management service software 111. The action is divided into two parts. In addition to the control action command (CAC), a number of formatted device read data are also added at the same time. This method is called device read data (Formatted Device). Values, FDVs) 223.

And the data record contains three levels, the first layer: the identification code of the control server, under which there will be device reading data (FDVs) 223 The file name and check code of the format file; the second layer: the device value (Device Values) of the device reading data (FDVs) 223, the file name and the check code list; the third layer: in the multi-section Device read data (FDVs) 223 attached to (Multipart).

A device read value data (Formatted Device Values, FDVs) 223; in the additional FDVs 223, Device Values is a two-dimensional form in the form of an electronic file (eg, the file name is csv), a two-dimensional form The vertical axis represents time, the horizontal axis represents different monitoring points, and the monitoring point (horizontal axis) information is not actually recorded in the Device Values, but is independently extracted and saved in the format file, device value. (Device Values) is preset to the contents of the format file, and is used as the monitoring point (horizontal axis) for filling in values.

In order to reduce the amount of data to further enhance the transmission efficiency, and at the same time take into account the simplicity of management and implementation, the method simultaneously adopts several strategies to achieve. For device reading data (FDVs) 223, the method separates the format (Format) from the data file of the device value (Device Values), and has a map file describing the Device Value Format, and Independently save the actual data file of Device Values; the advantage of this design is that according to the data collection strategy of different control servers, if the data file is saved as several data, then each data file will not be heavy. Overlay information related to "format" to avoid repeated formatting of the information. Then, when actually transmitting the data, the method first cuts the data size into a quantity of 10 KB, thereby avoiding the frequency of occupation. Wide negative effect.

By using the above-mentioned HTTP packet-based data transmission, the present invention provides a method for constructing a distributed energy-consuming device monitoring data summary report by using a device control system message exchange mechanism, and the steps include: a package device control system 112 has collected The power data step: the control action command (Control Action Command) is used to establish the header data such as the header and the body, and the sending step is divided into the instructions sent to the device control system 112, and the device. The data collection and collection sent by the control system 112 actively transmits the content of the encapsulated control action command (CAC) as the Http Post packet to the device control system 112 by the building energy management service software 111; The device control system 112 receives and parses the instructions, and the building energy management service software 111 receives the parsed data collection summary, and then receives and translates the instructions to the underlying device by the mediation layer library for the general control action instruction (CAC) instruction. Various control functions can be implemented.

Furthermore, the device-side mediation library 102 of the device control system 112 presets to collect the original data of the monitoring point every minute, and uploads the original data to the server-side intermediary of the building energy management service software 111 every two minutes. Layer library 101. The original data includes the original data file and the monitoring point number corresponding file, the original data file content includes: purpose (original data of each monitoring point), naming format (year/month/day, monitoring point controller number), content grid (File record time, monitoring point raw data value, monitoring point read status); and the monitoring point number corresponding file contains: purpose (storage under a controller, device number and monitoring point number correspondence), naming method (year/month/day, monitoring point controller number), content format (file name of the original data file), device number where the monitoring point is located, and monitoring point number.

In practical application, the method of the present invention has a process flow of equipment management and a data collection process, which are respectively introduced below.
