Referring to fig. 2, a schematic diagram of an intelligent energy monitoring and management system designed for the present application is shown. The cloud platform master station is used for processing electric energy data acquired by the acquisition device, specifically including data of energy sources such as water, electricity, natural gas and heat energy, and the acquisition electric energy data control device (namely the illustrated user side multi-resource acquisition electric energy data control device) is used for uploading data acquired by the acquisition layer to the cloud platform master station. And the cloud platform master station sends a control instruction to the electric energy data acquisition control device. And the electric energy data acquisition control device realizes energy-saving control and energy monitoring on an energy system. The acquisition layer device is used for acquiring energy data such as water, electricity, natural gas, heat energy and the like.
The electric energy data acquisition control device comprises a basic configuration module, a core control module and a user-defined module. Specifically, referring to fig. 3, a schematic structural diagram of a control device for collecting electric energy data provided in the embodiment of the present application is shown. The device comprises:
a base configuration module 301.
The basic configuration module 301 is configured to implement basic configuration for acquiring the energy data by the acquisition layer, including implementing power supply, storage, and communication functions. The basic configuration module can be connected to or disconnected from the electric energy data acquisition control device according to preset function requirements.
In this embodiment, the basic configuration module 301 includes a power module 3011, a storage module 3012, and a communication module 3013.
Specifically, the power supply module 3011 provides operating power to other functional modules. In the embodiment of the present application, the power module may be powered by a standard three-phase power supply, and simultaneously support dc power input. Even if one phase is lacked in the three phases, the power module can still supply power normally. In one possible implementation, the power module employs two outputs, one of which outputs DC24V for remote control of the acquisition loop. And one path of output direct current DC5V is used for controlling each functional module to work.
And the storage module 3012 is configured to store the acquired data. The storage capacity of the storage module is automatically adjusted according to the actual application scene. For example, in an actual application scenario, a large storage capacity is required, and a new storage module can be accessed to the control device for collecting electric energy data.

The control device for collecting the electric energy data has diversified communication modes and supports various communication protocols, so that the communication module is in a hot-pluggable mode, and networking in different communication modes is facilitated.
A core control module 302.
The core control module 302 is used for supplying power to the module power supplies of the basic configuration module, the core control module and the user-defined module according to a pre-stored power supply control strategy.
In a possible implementation manner, the power control strategy is allocated to the module of the microcomputer protection action module, namely, the module with higher real-time requirement, as a continuous power supply mode. For example, the electric quantity acquisition module and the control module have high real-time requirements and need to adopt continuous power supply. For functional modules that do not involve a microcomputer protection action module, a non-continuous power supply mode can be adopted. For example, the storage module and the human-computer interaction module have low requirements on real-time performance, and adopt a non-continuous power supply mode.
In one possible implementation, the core control module 302 may perform module sorting of the basic configuration module, the core control module, and the custom module according to a pre-stored cooperative work policy. Specifically, the functions of the work modules are prioritized according to the field application requirements, and when the shared bus is in a busy state, the shared bus is judged to transmit data according to the priority.
An exemplary illustration is as follows: the field application requirement is power supply → electric parameter acquisition → electric energy calculation → man-machine interaction → protection. The priority of each functional module is sorted into a power supply module, an electric parameter acquisition module, an electric energy metering module, a man-machine interaction module and a microcomputer protection action module.
In the embodiment of the application, except for the power module, each functional module can be upgraded by software to become a core control module.
In the embodiment of the present application, the core control module also enumerates descriptions of various functional modules, such as module addresses, module names, module service ranges, and module main data. The main data of the module comprises collected voltage, current, frequency and other electrical parameter data.
A custom module 303.
And the user-defined module is used for realizing the function expanding module according to the use scene requirements. The self-defining module can exit or access the electric energy data acquisition control device according to the actual requirements of an application field communication mode, a data acquisition type, a control mode, the number and the like according to the preset function requirements.
In the embodiment of the application, the self-defining module is at least one of an electric quantity collecting module, an electric energy metering module, a microcomputer protection action module, a residual electric quantity action module, a human-computer interaction module and an edge calculating module.
Wherein, electric parameter acquisition module: the method mainly comprises two types, wherein one type is electric parameter collection and mainly collects electric parameters such as voltage, current and frequency, the other type is standard analog quantity collection, and the method supports collection of standard analog quantity signals of 4 mA-20mA and DC 0V-DC 5V and can be selected according to actual requirements.
The electric energy metering module: the device has the functions of measuring electric parameters, electric energy, three-phase unbalance and frequency, and the measured data items comprise positive and negative peak flat valley active and reactive total electric energy, four-quadrant reactive electric energy, ABC three-phase and total active power, reactive power, power factors, voltage and current unbalance and the like.
The microcomputer protection action module: when the field power utilization condition has faults of overvoltage, overcurrent, short circuit and the like, the protection action receives a remote control command to carry out commands of tripping, closing and the like, so that the aims of reducing the fault range and quickly positioning the fault section are fulfilled.
Residual electric quantity action module: the circuit has a residual current monitoring function, and can receive a background remote instruction to realize the control execution of the residual current (electric leakage) protection function of the circuit.
A human-computer interaction module: the user side multi-resource electric energy data acquisition control device is provided with the LCD display and the keys, so that simple parameters can be conveniently checked on site, and the displayed information characters are clear and complete by adopting the liquid crystal screen and can be recognized without depending on an environmental light source. Meanwhile, the device is provided with local state indicator lamps, including a power-on indicator lamp, a communication indicator lamp and a fault indicator lamp, for indicating the working states of the device, such as power-on, communication, fault and the like.
An edge calculation module: the user side multi-resource electric energy data acquisition control device can locally calculate 10 fixed value out-of-limit protection function alarm events such as voltage out-of-limit, current out-of-limit, phase loss, voltage unbalance out-of-limit, temperature out-of-limit, residual current out-of-limit and the like according to a certain rule. At least 10 records of each event are stored. The event type can set the alarm function of the phase, and the alarm state is actively sent by the device.
In an exemplary mode, when a user needs to collect power parameters such as voltage, current and frequency, the user-defined module, namely the power parameter collection module, needs to be accessed to the control device for collecting power data. When the residual current monitoring function is not needed on site, the residual electric quantity action module quits the electric energy data acquisition control device.
Regarding the basic configuration module 301, or the custom module 302 exits the electric energy data collection control device, or when the function module needs to be replaced, that is, the function module needs to exit the electric energy data collection control device. At this time, the core control module 302 autonomously selects a functional module that needs to be exited or replaced according to the description of each enumerated functional module, and executes automatic exiting or replacing of the functional module. And after replacement, the core control module 302 readjusts the co-operating strategy and the power control strategy.
When the functional module is accessed to the electric energy data acquisition control device, the functional module can be accessed in an autonomous registration mode. The specific implementation is shown in fig. 4.
Referring to fig. 4, a schematic flowchart of a method for autonomous registration of a function module according to an embodiment of the present application is provided. The method comprises the following steps:
s401: the function module initiates a registration request to the core control module.
When the electric energy data acquisition control device is powered on or a new functional module is accessed, the functional module initiates a registration request to the core control. The registration request includes information such as module address, module type, and module task.
S402: the core control module receives the registration request.
S403: the core control module distributes a cooperative working strategy and a power supply control strategy.
And the core control module distributes a cooperative working strategy and a power supply control strategy to the functional module according to the received registration request. I.e. assigning the functional modules a combined priority in the device, and a power mode.
S404: the core control module sends a registration confirmation instruction to the functional module.
After the cooperative working strategy and the power supply control strategy are distributed, the core control module sends a registration confirmation instruction to the functional module. The registration confirmation instruction comprises information such as a module address, a module type, a module task and the like.
S405: and the functional module confirms and sends the confirmation result to the core control module.
And the functional module autonomously confirms whether the functional module is successfully registered according to the registration confirmation instruction and sends a confirmation result to the core control module.
In a possible implementation manner, the functional module receives the registration confirmation instruction, autonomously confirms that the registration result is successful, and sends the registration result to the core control module.
In a possible implementation manner, if the functional module does not receive the registration confirmation instruction, the functional module confirms that the functional module is not successfully registered, stops the registration confirmation, and does not send the confirmation result to the core control module.
S406: the core control module judges whether the registration time is overtime. If yes, go to step S403. Otherwise, S407 is executed.
And after the core control module receives the confirmation result sent by the function module, the core control module judges whether the registration time length exceeds the preset time length. If yes, the process returns to S403 to re-register. Otherwise, updating the module library.
S407: and the core control module updates the module library and starts a new function module.
And the core control module updates the module library and starts the functional module.
S408: the function module starts to operate.
Therefore, the functional module realizes plug and play of the module through autonomous registration. The system realizes random combined use according to different requirements and specific application scenes of different clients and according to actual requirements of application field communication modes, data acquisition types, control modes, quantity and the like, meets the use requirements of the clients, does not need to be completely replaced when functions are increased or decreased, is convenient for subsequent installation and maintenance, and saves cost.
In the embodiment of the application, each module adopts a unified preset bus and interface mode. The following describes a unified default bus and an interface method in detail.
Each functional module self-defines a bus mode and comprises an input port and an output port, wherein the input port and the output port adopt 12 buses. Referring to fig. 5, a schematic view of a bus port of a functional module according to an embodiment of the present disclosure is shown.
Wherein the 12 buses of the input port and the output port each include: two power lines: DC5V and GND, 4 data line group differential lines in total: i.e., transmit and receive (TX +, TX-; RX +, RX-), two data error signal lines: transmit/receive error prompt (TX _ ER/RX _ ER), two data valid signal lines: 2 spare control lines are designed for sending an enable signal and a receiving data valid signal (TX _ EN/RX _ DV). The power sharing between the modules is realized through the power line, the plug and play of each module is realized through the data line, and the effective and stable work of each module is ensured through the error prompt line and the effective data signal line. The communication mode can be matched with a flexible working mode.
Referring to fig. 6, a schematic diagram of module splicing provided in the embodiment of the present application is shown. The input port and the output port of each module are both in the self-defined bus mode shown in fig. 5, the output port of the module 1 is connected with the input port of the module 2, the output port of the module 2 is connected with the input port of the module 3, and the output port of the module … …, the module n-1, is connected with the input port of the module n.

From a software perspective, the modular combination is based on a client-server based message publish/subscribe transport protocol. In one possible implementation, the transmission protocol is the standard MQTT protocol. The core control module is used as a system information transmission hub to serve as a server, other function modules serve as clients, and the core control module is responsible for coordinating information communication among the modules and managing the function modules so as to ensure smooth communication among the modules and correct transceiving. The method mainly comprises the steps that a core control module receives online information and an application request of a functional module of an access system, processes subscription and unsubscribe requests from the functional module and sends related information to the subscribed functional module; the function module issues other (related) module subscription information, subscribes the information issued by other (related) function modules, and disconnects the connection with the core control unit.
The software design basis of the modularized combination is based on a unified standard MQTT protocol so as to realize the purposes of flexible configuration and random combination. Meanwhile, the MQTT is a message queue protocol and has the characteristics of small transmission, low overhead, simplicity, stability and minimized data transmission and exchange.
