Description

Technical Field

[0001] This invention relates to the field of low-voltage electrical equipment control technology, and more specifically, to a low-voltage remote control system based on mobile internet. Background Technology

[0002] Existing low-voltage control systems commonly employ remote control structures based on local area networks (LANs) or simple internet access. A typical operational flow is as follows: the user inputs control commands on a local control terminal or web interface. These commands are transmitted to the control server via a gateway device and parsed by the server into internal commands executable by the device. The control server then sends the parsed internal commands to the control module of the controlled low-voltage equipment, which drives relays, contactors, or voltage regulators to complete the specified operation. After the equipment completes its action, its internal detection circuits collect its current operating status and transmit the collected data, such as voltage, current, and switch status, back to the control server via the gateway. Finally, the control server presents the results on the local terminal interface or web interface, achieving traditional remote control and status monitoring functions. Such systems typically rely on fixed networks, LAN protocols, or traditional industrial communication methods to achieve the entire command flow and data transmission.

[0003] However, the aforementioned existing technologies still have several limitations and shortcomings in practical applications: First, traditional remote control relies heavily on fixed terminals or local area network environments, making it difficult to adapt well to mobile internet environments, thus limiting user access across regions; Second, the instruction encapsulation methods, data parsing methods, and device interaction processes in existing systems often lack modular structures, making it difficult to flexibly migrate or expand between different devices; Third, existing technologies generally lack clear data structure layering in the link from the mobile terminal to the device terminal, making the relationship between the input, parsing, execution, and feedback of control instructions unclear, which is not conducive to building an end-to-end remote control system with clear logic; Fourth, the cloud data management structure of traditional systems is relatively crude, often using simple storage methods, making it difficult to perform structured indexing of device status and failing to meet the need for rapid status retrieval in multiple devices and scenarios; Fifth, in terms of device feedback, existing technologies generally rely on single or periodic collection, lacking a mechanism to couple the execution process with status monitoring to form standardized status data frames, making device feedback unsuitable for further data analysis or system expansion. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a low-voltage remote control system based on mobile Internet, which solves the problems mentioned in the background art through the following solution.

Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the overall structure of the present invention. Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] refer to Figure 1 The low-voltage remote control system based on mobile internet shown includes: Mobile terminal operation module: used to set instructions for low-voltage equipment on the mobile terminal interface, and transmit relevant instructions to the instruction parsing module via the communication network. First, the instruction input unit receives the control parameters from the operator, and then the parameter verification unit verifies the input control instructions. Based on the verification result, the instruction encapsulation unit encapsulates the control data into a data packet of a preset format and transmits the data packet to the instruction parsing module.

[0018] The instruction input unit presents preset control entry points in the form of buttons, sliders, or numerical input boxes in the application interface of the mobile terminal, enabling the operator to select device switch control, set voltage parameters, or set timed execution parameters on the interface. After the operator completes the input, the instruction input unit summarizes the control type information, parameter content information, and execution timing information generated in the interface into raw control data in an internal format for subsequent processing.

[0019] After the raw control data is transmitted to the parameter verification unit, the parameter verification unit compares it with the preset parameter template, legal range, and encoding format inside the system to determine whether the raw control data meets the requirements in terms of numerical range, format arrangement, number of parameters, and encoding consistency. During the verification process, the parameter verification unit compares the raw control data item by item according to the internal template. Data with the same format and within the preset range remains unchanged, while data that does not meet the requirements returns a prompt message so that the operator can re-enter the data. After all verifications pass, the verified control data is output to the instruction encapsulation unit.

[0020] After receiving the verified control data, the instruction encapsulation unit writes the operation type, parameter content, time information, and operator identifier into the corresponding fields of the data structure in sequence according to the data packet encapsulation format set by the system. After encapsulation, a data packet for network transmission is formed. During the encapsulation process, the instruction encapsulation unit also supplements the necessary field order and length information to ensure that the data packet meets the format requirements agreed upon by the system. After the data packet is formed, it is sent to the instruction parsing module.

[0021] The entire mobile terminal operation module processes the control information input by the operator in sequence through the instruction input unit, parameter verification unit, and instruction encapsulation unit, so that the control information input by the operator is transformed into structured data suitable for network transmission for subsequent modules to parse.

[0022] Command parsing module: It is used to receive data packets from the mobile terminal operation module and transmit the parsed internal control commands to the device control interaction module. First, the data packet content is received by the data receiving unit, and then the format parsing unit is used to parse the data packet format. After the parsing is completed, the command conversion unit converts the parsed content into a control format that the device can recognize, and then transmits it to the device control interaction module according to the system status.

[0023] The data receiving unit maintains a data connection with the communication network and continuously receives data packets transmitted by the mobile terminal operation module on the system's preset listening port. After receiving the data packet, the data receiving unit performs preliminary identification on the length, integrity, and basic encoding format of the data packet, and after confirming that the data packet meets the preset reception conditions, it passes it to the format parsing unit so that the format parsing unit can perform subsequent parsing processing based on the complete data.

[0024] After receiving the data packet output by the data receiving unit, the format parsing unit parses the header information, instruction content, parameter content, timestamp, and source identifier of the data packet item by item according to the data structure set in the system. The format parsing unit extracts the instruction type, the parameter value associated with the instruction, and the identification information of the mobile terminal in sequence by identifying the structural order and length of the corresponding fields. During the parsing process, the field order of the data remains unchanged, so that the parsed content can be directly read and used by the instruction conversion unit.

[0025] After receiving the instruction type and parameter content output by the format parsing unit, the instruction conversion unit maps the parsed instruction content into an internal control instruction that can be recognized by the device control interaction module according to the internal control format defined by the system. The instruction conversion unit converts different types of control instructions into corresponding internal control formats such as relay control codes or voltage regulation trigger codes by directly calling the predefined mapping relationship. After the conversion is completed, the converted internal control instruction is output to the device control interaction module, so that the device control interaction module can execute the corresponding control action based on the internal control instruction.

[0026] Equipment control interaction module: It is used to write internal instructions from the instruction parsing module into the low-voltage equipment control terminal, and output the real-time status of the equipment during the execution process to the data feedback module after being processed by the status monitoring unit, control execution unit and field feedback unit. The equipment control interaction module realizes the triggering of equipment actions, the acquisition of equipment status and the generation of control response through the above units.

[0027] The status monitoring unit establishes an electrical connection with the sampling node of the low-voltage equipment and uses a current transformer, voltage sampling module and thermal sensor to collect operating parameters in real time. The collected analog signal first enters the signal conditioning circuit, and after filtering, amplification and isolation, it is input to the analog-to-digital conversion module. The analog-to-digital conversion module converts the analog quantity into a digital quantity. The converted digital quantity is transmitted to the processing core of the equipment control interaction module through the internal bus. The processing core completes data reading and buffering according to the monitoring cycle defined by the system.

[0028] After receiving the internal control command output by the command parsing module, the control execution unit provides a drive signal to the relay coil or contactor drive terminal through the control drive circuit to realize the opening, closing or adjustment operation of the low-voltage equipment. When the control command involves voltage regulation, the control execution unit maps the control quantity to the firing angle, duty cycle or step command of the voltage regulation module, and drives the relevant output interface to perform the adjustment action. After completing the action, the control execution unit temporarily stores the execution status for the field feedback unit to read.

[0029] The field feedback unit reads the current monitoring values ​​of the status monitoring unit and the action status of the control execution unit, and combines the two to form a feedback data structure. This data structure takes the device action result as the core, and combines the information such as whether the action is completed, the execution time, the monitoring value range, and the device location through an internal protocol to form the final status data frame. The status data frame is transmitted to the data feedback module through the internal communication interface for subsequent uploading to the cloud management module.

[0030] Data feedback module: It organizes the status data from the device control interaction module and sends it to the cloud management module. The data acquisition unit collects the feedback information from the device, and the data processing unit performs structured processing on the data. Then, the information uploading unit transmits the processed data to the cloud management module, so that the cloud can return the latest status according to the usage requirements of the mobile terminal operation module.

[0031] After obtaining status data frames from the field feedback unit, the data acquisition unit temporarily stores the data in the buffer area and reads the data in the buffer according to the acquisition cycle set by the system. The data acquisition unit marks the source device number and acquisition time of each data frame through the data channel and adjusts it into a unified data structure for further processing by the data processing unit.

[0032] The data processing unit parses the status data from the data acquisition unit, recombining the device number, action type, monitoring parameters, execution status, and timestamp according to the system-defined field order. The recombined data is then fitted with a verification field, including a CRC checksum or hash digest, to ensure data consistency during subsequent uploads. The processed data is stored in the output buffer in a unified structure format, ready for transmission by the information upload unit.

[0033] The information uploading unit encapsulates the data structure output by the data processing unit into a network transmission packet according to the upload interface format specified by the cloud management module. During encapsulation, encryption fields and session identifiers are added. After completing TLS or other security layer negotiation, a data upload channel is established with the cloud management module through the communication link. After a successful handshake, the information uploading unit sends data according to the preset upload strategy and receives confirmation information returned by the cloud after the transmission is completed to ensure the reliability of data upload.

[0034] The cloud management module is used to store and manage the status data uploaded from the data return module, and return device status information according to the request of the mobile terminal operation module. The cloud management module first records the data uploaded each time through the status storage unit, and then establishes an index structure of device status through the data index unit. When the mobile terminal operation module needs to query, the remote retrieval unit returns the corresponding status data according to the index, thus forming a two-way closed loop with the entire system.

[0035] The status storage unit stores the uploaded data from the data return module into the cloud database according to the device number. The storage process uses structured tables, key-value stores, or time-series databases, depending on the system design. When new status data arrives, the status storage unit sorts the data according to the timestamp and adds a storage index to ensure that it can be queried in chronological order later.

[0036] The data indexing unit indexes all stored status data, using inverted indexes, hash indexes, or multi-level index structures to enable fast retrieval of device numbers, instruction types, status parameters, and time intervals. In actual operation, the data indexing unit dynamically updates the index structure based on newly added data to ensure that the cloud management module can still return retrieval results with a short delay under high concurrency requests.

[0037] When the remote retrieval unit receives a status query request from the mobile terminal operation module, it first parses the requested device number and time range, then retrieves the corresponding status record through the data indexing unit. The retrieved data is reassembled into a status return packet, and after adding a response identifier and timestamp, it is returned to the mobile terminal operation module through the network interface. The entire retrieval process conforms to the system-defined response protocol, enabling the mobile terminal to view the latest device operation status in real time.

[0038] Secondly: The accompanying drawings of the embodiments disclosed in this invention only involve the structures involved in the embodiments disclosed in this invention. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this invention can be combined with each other. In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
