[0048] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0049] In the following description, the terms "first\second" involved are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0051] It should be understood that in the various embodiments of the present application, the size of the serial number of each implementation process does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0052] The technical solution of the present application relates to an energy-saving protector and a second device of a test device. The energy-saving protector can be a regulating device capable of regulating current, voltage, etc. The second device can be a device with a motor.

[0053] like Figure 1 The energy-saving protector of the embodiment of the present application is shown, and the energy-saving protector comprises: a sensor group 11, an energy-saving module 12, a power on / off module 13 and a controller 14;

[0054] The sensor group 11 is used to collect operating parameter data of the test device;

[0055] The controller 14 receives the operating parameter data and determines the operating state of the test device based on the operating parameter data, and sends a first control instruction to the energy-saving module 12 or sends a second control instruction to the power on / off module 13 according to the operating state;

[0056] The energy-saving module 12 adjusts the operating parameters according to the first control instruction so that the operating parameters are consistent with the current operating state of the test device; the first control instruction is used to control the operating parameters of the test device to be adjusted to be consistent with the current operating state;

[0057] The power on / off module 13 cuts off the power supply according to the second control instruction; the second control instruction is used to control the test device to cut off the connection with the power supply when the operating state of the test device is abnormal.

[0058] It can be understood that in the present application, the energy-saving protector is connected to the test device and can collect the operating parameter data of the test device, so as to know the operating status of the test device.

[0059] Specifically, the sensor group 11 in the present application includes multiple sensors, such as current sensors, voltage sensors, temperature sensors, residual current transformers, etc., and may also include other sensors, which are not limited in the present application. These sensors can collect energy usage data and environmental parameters of the equipment in real time, and provide key information for energy efficiency evaluation, fault prediction and monitoring of environmental conditions of the equipment. The voltage of the test device can be collected by the voltage sensor, the current sensor can collect the current of the test device, and the temperature sensor can collect the temperature of the motor of the test device. After obtaining the operating parameter data, the controller 14 of the present application can determine the operating state of the test device according to the operating parameter data. For example, after collecting the current and voltage of the test device, the power of the test device can be calculated, and the load of the test device can be determined according to the power. If the load of the device is low or idle, the energy-saving module 12 can adjust the operating parameters, such as lowering the current and voltage, and putting the device into a dormant state to reduce power consumption. When the device needs to run, the energy-saving module 12 can wake up the device in time to ensure that it can work normally. If the load is too high and the motor of the test device is at risk of burning, the connection between the test device and the power supply, or the power supply of the motor in the test device, can be cut off by the power on / off module 13, thereby ensuring the safety of the test device.

[0060] It should be noted that the controller 14 in the present application can calculate the operating state of the test device according to the operating parameter data, and generate the corresponding first control instruction or second control instruction according to the operating state, wherein, if the operating state does not conform to the current operating state of the test device, for example, according to the actual load condition and energy demand of the equipment, the operating parameters of the equipment, such as voltage, current, etc., are dynamically adjusted to achieve the purpose of energy saving, and the first control instruction is generated at this time. If the operating state is abnormal, for example, the current, voltage and other parameters in the circuit are monitored in real time, once an abnormality (such as overload, short circuit, leakage, etc.) is found, the circuit is immediately cut off to prevent electrical fires and electric shock accidents. After the circuit fault is resolved, the power supply can be automatically or manually restored as needed.

[0061] The energy-saving protector provided in the present application can realize real-time and intelligent monitoring of the energy usage of the test device, automatically adjust the working status of the equipment according to the preset energy-saving strategy, realize effective energy saving, and cut off the power supply in time under abnormal circumstances to protect the safety of the equipment.

[0062] In some embodiments, the energy-saving protector further comprises:

[0063] The touch control module 15 is used to receive the setting instruction of the operating parameters and display the current operating parameter data of the test device;

[0064] The touch control module 15 is connected to the controller 14 .

[0065] It is understandable that the energy-saving protector provided in the present application is also provided with a touch module 15, which includes a human-computer interaction interface, displays information such as energy usage and energy-saving effects, and allows users to set energy-saving parameters. The touch module 15 provided in the present application can display the operating parameter data of the test device, and the user can also input the parameter data of the test device operation through the touch module 15. The touch module 15 provided in the present application can display various parameters and status information of the circuit breaker in real time, including real-time data such as voltage, current, power, power factor, and fault alarm information. The display of the touch module 15 helps the user to understand the operating status of the circuit in a timely manner, so as to take corresponding measures. The human-computer interaction interface provides an interactive interface between the user and the energy-saving module 12, so that the user can remotely operate the energy-saving module 12, such as remotely controlling switches, setting parameters, etc. This interactive capability not only improves the convenience of use, but also enables the energy-saving module 12 to automatically adjust the operating mode according to the power grid conditions, and realize more intelligent management.

[0066] In some embodiments, the energy-saving protector further comprises:

[0067] Communication module 16, used to connect to a server; the server is provided with standard data of operating parameters;

[0068] The controller 14 calculates the operating data of the test device according to the operating parameter data, subtracts the operating data from the standard data, compares the difference with a preset threshold, and determines to generate a first control instruction or a second control instruction according to the comparison result.

[0069] In the present application, the energy-saving protector is connected to the server via the Internet of Things communication module 16. The server is preset with standard data of operating parameters. The controller 14 can calculate the actual load condition and energy demand of the test device based on the operating parameter data, and after comparing the actual load condition and energy demand with the standard data, generate a first control instruction or a second control instruction based on the comparison result, and provide the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation.

[0070] The energy-saving protector can also be connected to the test device through the Internet of Things communication module 16, and the energy-saving protector can also communicate wirelessly with other Internet of Things devices or cloud platforms through the Internet of Things communication module 16. By integrating intelligent algorithms and sensor technology, fault information is pushed in time after big data analysis.

[0071] In some embodiments, calculating the operating data of the test device according to the operating parameter data, subtracting the operating data from the standard data, comparing the difference with a preset threshold, and determining to generate a first control instruction or a second control instruction according to the comparison result includes:

[0072] If the difference between the operating data and the standard data is lower than a preset threshold, generating a first control instruction;

[0073] If the difference between the operating data and the standard data is higher than a preset threshold, a second control instruction is generated; wherein the operating data includes the load power of the test device.

[0074] Specifically, the controller 14 of the present application serves as a control center to process sensor data, execute energy-saving strategies, and control the on-off module 13. The controller 14 is responsible for receiving real-time data from a sensor array (including current sensors, residual current transformers, voltage sensors, temperature sensors, etc.). These data are processed and analyzed to determine whether the circuit state is abnormal. According to the analysis results, the on-off of the IGBT module is controlled to achieve circuit protection and energy-saving functions. The controller 14 is connected to the Internet of Things platform through a built-in communication module 16. Remote transmission and reception of data is achieved, allowing users to remotely monitor and manage circuit status through mobile phone APP or computer software. The controller 14 has a self-diagnosis function and can automatically detect and identify fault types. The built-in intelligent algorithm can analyze and process the collected data and provide a power consumption analysis report. Help users understand power usage habits, optimize power usage structure, and reduce energy consumption costs.

[0075] After the second control instruction is generated, the power-on and power-off module 13 receives the quality of the controller 14 to realize the power-on or power-off control of the equipment. According to the preset power consumption strategy or real-time power consumption data, the on and off of the circuit is intelligently controlled. During the peak power consumption period or when the power grid is overloaded, some non-essential circuits are automatically cut off to reduce energy consumption and reduce the burden on the power grid. Real-time monitoring of current, voltage and other parameters in the circuit, once an abnormality (such as overload, short circuit, leakage, etc.) is found, the circuit is immediately cut off to prevent electrical fires and electric shock accidents. After the circuit fault is eliminated, the power supply can be automatically or manually restored as needed. Through the Internet of Things technology, the power-on and power-off module 13 is connected to the remote monitoring platform to realize remote monitoring and management of the circuit. Users can view the circuit status, control the switch, and receive early warning information in real time through mobile phone APP or computer software.

[0076] In some embodiments, the energy-saving module 12 includes: a rectifier unit, a filter unit, a brake unit and an inverter unit connected in sequence;

[0077] The rectifying unit is used to convert the alternating current used by the testing device into direct current;

[0078] The filtering unit is used to filter the direct current;

[0079] The brake drive unit is used to adjust the current operating parameters;

[0080] The inverter unit is used to convert the regulated direct current into alternating current.

[0081] The energy-saving module 12 provided by the present application, wherein the rectifier unit converts AC power with a fixed operating frequency into DC power, the filter unit filters the DC power, the brake drive unit adjusts the current operating parameters, and the inverter is an electronic switch composed of a high-power switching transistor array, which converts DC power into square waves of different frequencies, widths, and amplitudes, so that the energy-saving module 12 controls the amplitude and pulse width of the output square wave, so that the AC power superimposed as an approximately sinusoidal wave drives the AC motor.

[0082] Specifically, in the present application, the energy-saving module 12 monitors the operating status and parameters of the test device in real time, such as current, voltage, power factor, etc., and dynamically adjusts the operating parameters of the equipment, such as voltage, current, etc., according to the actual load condition and energy demand of the test device, so as to achieve the purpose of energy saving. At the same time, the energy-saving module 12 also has fault warning and fault handling functions, which can timely discover and handle abnormal conditions of the equipment to prevent energy waste and safety hazards. The present application is an electric power control device that controls AC motors by changing the working power frequency of the motor using frequency conversion technology and microelectronics technology. It is mainly composed of rectification (AC to DC), filtering, inversion (DC to AC), braking unit, drive unit, braking unit, etc. The output power voltage and frequency are adjusted by intelligently adjusting the internal IGBT opening and closing through the big data algorithm, and the required power supply voltage is provided according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation.

[0083] In some embodiments, the energy-saving protector further comprises:

[0084] An alarm module 17, used for generating an alarm when the second control instruction is generated;

[0085] The alarm module 17 is connected to the controller 14 .

[0086] It is understandable that current protection, voltage protection, temperature protection, short circuit and ground fault protection and leakage protection can be implemented in the present application. Among them, current protection is specifically to monitor the current change of the equipment in real time to determine whether there are abnormal conditions such as overload or short circuit. Once an abnormality is found, the power supply is immediately cut off or other protective measures are taken to prevent equipment damage or fire and other safety accidents. Voltage protection is specifically to monitor the voltage change of the equipment to determine whether there are abnormal conditions such as overvoltage or undervoltage. According to the voltage change, adjust the operating parameters of the equipment or cut off the power supply to ensure that the equipment operates within a safe voltage range. Temperature protection is specifically to monitor the temperature change of the equipment in real time through the built-in temperature sensor. Once the temperature exceeds the preset safety threshold, the early warning or protection measures are immediately triggered to prevent the equipment from overheating and causing safety accidents such as fire. Short circuit and ground fault protection is specifically to monitor the short circuit and ground fault of the equipment in real time. Once a short circuit or ground fault is found, the power supply is immediately cut off to prevent the fault from expanding or causing more serious safety accidents. Leakage protection is specifically to monitor the leakage in real time. Once a leakage is found, the power supply is immediately cut off to prevent the fault from expanding or causing more serious safety accidents.

[0087] The energy-saving protector provided in the present application can sense the load changes of the equipment by monitoring the load of the test device in real time. According to the load changes, the operating parameters of the equipment, such as voltage, current, etc., are dynamically adjusted to match the actual load requirements of the equipment. When the load of the test device is low or idle, the energy-saving protector puts the device into a dormant state to reduce power consumption. When the device needs to run, the energy-saving protector can wake up the device in time to ensure that it can work normally. The energy-saving protector can also intelligently adjust the power output of the device according to the actual load of the test device. When the equipment load is low, the power output is reduced to reduce energy consumption; when the equipment load is high, the power output is increased to meet the performance requirements of the device. The task scheduling strategy can be optimized according to the priority and urgency of the task. By merging and batching tasks, the overhead of task switching and resource allocation is reduced, and the operating efficiency of the test device is improved.

[0088] like Figure 2 As shown, the embodiment of the present application also provides a control method for energy-saving protection, the method comprising:

[0089] S201, collecting operating parameter data of the test device;

[0090] S202, determining an operating state of the test device based on the operating parameter data, and generating a first control instruction or a second control instruction according to the operating state;

[0091] S203, adjusting the operating parameters according to the first control instruction so that the operating parameters conform to the current operating state of the test device; or cutting off the power supply according to the second control instruction;

[0092] Among them, the first control instruction is used to control the operating parameters of the test device to be adjusted to match the current operating state; the second control instruction is used to control the test device to cut off the connection with the power supply when the operating state of the test device is abnormal.

[0093] The control method of the energy-saving protector provided in the present application can monitor the energy usage of the equipment in real time, automatically adjust the working state of the equipment according to the preset energy-saving strategy, realize effective energy saving, and cut off the power supply in time under abnormal circumstances to protect the safety of the equipment.

[0094] like Figure 3 As shown, an embodiment of the present application provides an energy-saving protection system, comprising the energy-saving protector 1, the test device 2, the server 3 and the client 4 described in any of the above embodiments, one end of the energy-saving protector 1 is connected to the test device 2, and the other end is connected to the server 3, and the client 4 is connected to the server 3.

[0095] Reactive power not only increases line loss and heating of equipment, but more importantly, the reduction of power factor leads to a reduction in active power of the power grid. A large amount of reactive electric energy is consumed in the line, and the equipment is inefficient and wasteful. The energy-saving protector 1 provided by the present application reduces reactive loss and increases the active power of the power grid due to the effect of the internal filter capacitor of the energy-saving module. In addition, the hard start of the motor of the test device causes a serious impact on the power grid, and also places too high requirements on the capacity of the power grid. The large current generated during startup and the damage to the baffle and valve during vibration are extremely great, which is extremely detrimental to the service life of the equipment and pipelines. After using the energy-saving module, the soft start function of the energy-saving module will make the starting current start from zero, and the maximum value will not exceed the rated current, which reduces the impact on the power grid and the requirements for power supply capacity, and extends the service life of the equipment and valves. The maintenance cost of the equipment is saved.
