[0017] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0018] In actual industrial sites, the power supply of various types of equipment is usually obtained from a distribution cabinet (box). Among them, a three-phase AC distribution cabinet generally includes components such as an electric meter, a mutual inductor, an AC contactor, a protective device, buttons, and indicator lights. The functions of the distribution cabinet include power metering, AC on / off control, and abnormal power consumption protection.

[0019] In most scenarios, there are changes in electrical equipment, such as: the electrical equipment under a distribution cabinet is used by multiple personnel from different units at different times, and there are changes in the use of electrical equipment. In addition, when the electrical equipment under the distribution cabinet is replaced, it is necessary to readjust the action parameters of the protection device in the distribution cabinet for different electrical equipment to ensure the effective action of the protection device. At the same time, the change of electrical equipment will also be accompanied by the need for energy sharing and billing, that is, it is necessary to record the energy usage of different electrical equipment to share the cost.

[0020] In the related art, manual operation is required on site. Specifically, the AC contactor is controlled to be closed and disconnected by manually pressing the button on the distribution cabinet, thereby controlling the on and off of the power supply of the electrical equipment under the distribution cabinet. When the electrical equipment is replaced, the action parameters of the protection device are manually adjusted to match the power and other performance of the electrical equipment. When different electrical equipment are replaced, manually adjusting the action parameters of the protection device is troublesome and prone to missed operations and parameter errors, resulting in poor protection effect.

[0021] In addition, when different electrical equipment switches to use electricity, it is necessary to record the electricity usage of the electrical equipment by recording the meter reading or using a card-inserted meter. Specifically, on the one hand, in the card-inserted meter distribution cabinet, each time different electrical equipment is powered on to start, the corresponding meter card needs to be inserted into the meter of the distribution cabinet. Then, press the start button on the distribution cabinet, the AC contactor is energized, and the electrical equipment is powered on. When the meter card is pulled out or the stop button on the distribution cabinet is pressed, the AC contactor is disconnected, the electrical equipment is disconnected from the power supply, and the meter card will record the energy consumption of this period. On the other hand, in the ordinary meter distribution cabinet, each time different electrical equipment is powered on to start, it is necessary to manually record the meter reading and time of the distribution cabinet, then press the start button, the AC contactor is energized, and the electrical equipment is powered on. When the stop button is pressed, the AC contactor is disconnected, and the electrical equipment is disconnected from the power supply. Then manually record the meter reading and time to calculate the energy consumption of this period. Or the electricity cost sharing ratio can be estimated according to the electricity consumption period of different electrical equipment. Whether reading the meter reading or using a card meter to record manual data, it is necessary to open the power distribution cabinet, which is cumbersome and prone to errors. Users cannot obtain relevant electricity consumption information of electrical equipment according to their needs.

[0022] Based on the many limitations in the related art, this embodiment provides an electric energy monitoring method that can be applied to a power distribution device, a server and a user end, wherein the server can communicate with the power distribution device and the user end, without cumbersome manual operations, to achieve intelligent control. Figure 1 As shown, this embodiment is described by applying the method to a power distribution device, a server and a user end, and includes the following steps:

[0023] Step 101: The server receives device information, parameter protection rules and control instructions sent by the user, and sends the device information, parameter protection rules and control instructions to the power distribution device.

[0024] In this embodiment, the user's login information can be associated with the information of multiple electrical devices in the user terminal to meet the needs of time-sharing use of multiple electrical devices in actual application scenarios and improve the flexibility of equipment use. When using and replacing electrical equipment, there is no need for manual on-site operation. The user only needs to determine the corresponding equipment information in the user terminal according to the electrical equipment to be used this time, and set different parameter protection rules for different types of electrical equipment to achieve personalized abnormal protection for various electrical equipment, ensuring that each electrical equipment can operate under the protection mechanism that best suits its characteristics, reducing the risk of equipment damage. Then, the corresponding control instructions are set according to the use requirements, so that the user terminal sends the equipment information, parameter protection rules and control instructions to the server, and the server then transfers the equipment information, parameter protection rules and control instructions to the power distribution device, so as to achieve remote control of the electrical equipment and improve the convenience and efficiency of operation. Among them, the control instructions include start instructions and stop instructions, which are used to instruct the start and stop of the electrical equipment.

[0025] For example, based on actual application scenarios, the electrical equipment used by each user is relatively fixed. Therefore, when the user uses the user terminal for the first time, he needs to enter the user ID, the device information associated with the user ID, and the parameter protection rules corresponding to the device information in the user terminal. The user terminal automatically saves the information entered by the user. When the user uses it subsequently, he can directly select the required content on the user terminal interface.

[0026] Step 102: The power distribution device receives device information, parameter protection rules and control instructions sent by the server.

[0027] Step 103, the power distribution device controls the closing or opening of the power switch module associated with the target power-consuming device according to the control instruction, so that the target power-consuming device is connected to or disconnected from the power supply; wherein the target power-consuming device is determined according to the device information.

[0028] Among them, the power distribution device includes a power switch module and an electric energy metering module. The power switch module is used to control the connection or disconnection of the power supply of the electrical equipment, such as a circuit breaker, an AC contactor, a magnetic latching relay, etc. The electric energy metering module is used to collect the power consumption data of the electrical equipment.

[0029] In this embodiment, through a specific circuit connection, the power switch module in the distribution device is matched one-to-one with the electrical equipment corresponding to the device information stored in the user end, so as to control the connection or disconnection of the power supply of each electrical equipment respectively, thereby realizing remote control of the start and stop (start or stop) of each electrical equipment loaded under the distribution device.

[0030] Exemplarily, the power distribution device determines the target power device that needs to be controlled this time based on the device information, and then controls the closing or opening of the power switch module associated with the target power device according to the control instruction. For example, if the control instruction is a start instruction, the power distribution device controls the closing of the power switch module associated with the target power device so that the target power device is powered on, thereby remotely starting the target power device. Similarly, if the control instruction is a stop instruction, the power distribution device controls the opening of the power switch module associated with the target power device so that the target power device is powered off, thereby remotely stopping the target power device.

[0031] It should be noted that data communication can be established between the user end and the server through the network, and communication can be established between the distribution device and the server through the Internet of Things to achieve control of specific modules in the distribution device.

[0032] Step 104: The power distribution device collects power consumption data of the target power-consuming equipment through the power metering module.

[0033] In this embodiment, the power metering module in the power distribution device is used to collect power consumption data of the target power-consuming equipment, so as to provide basic data for monitoring the operation of the target power-consuming equipment.

[0034] Specifically, similar to the power switch module, the power metering module in the power distribution device can also correspond one-to-one with the power consumption equipment corresponding to the device information stored in the user end, so as to accurately collect the power consumption data of each power consumption equipment, reflect the actual power consumption of each power consumption equipment, and provide accurate data to support energy consumption sharing and billing. Exemplarily, the power distribution device collects the power consumption data of the power consumption equipment according to the second preset sampling period through the power metering module, wherein the second preset sampling period is used to determine the frequency of collection, which is determined according to the accuracy requirements of the power consumption data in the actual application scenario. For example, if it is necessary to understand the power consumption changes of the power consumption equipment more frequently, a shorter second preset sampling period can be set, such as 0.5 seconds, 1 second, etc.

[0035] It should be noted that the electricity consumption data may include electrical quantity data and electrical energy data. For example, the electrical quantity data includes voltage, current, frequency, impedance and capacitance, etc., and the electrical energy data mainly consists of power and time.

[0036] Step 105: The power distribution device adjusts the power switch module according to the power consumption data and the parameter protection rule, and determines the status information of the target power-consuming device.

[0037] In this embodiment, the power distribution device dynamically adapts the performance of target power equipment of different power types according to the power consumption data and the parameter protection rules issued by the server, monitors the operation of the target power equipment, performs abnormal protection on the target power equipment, and protects the power distribution device and the power equipment from damage caused by failures, which is convenient and safe. At the same time, the power distribution device monitors the start and stop status of the target power equipment in real time according to the current data in the power consumption data, and determines the status information of the target power equipment for query by the user end.

[0038] Furthermore, as a refinement and extension of the specific implementation methods of the above-mentioned embodiments, in order to fully illustrate the specific implementation process of this embodiment, the step of the power distribution device determining the status information of the target power equipment includes: if the current data in the power consumption data is greater than a preset threshold, the power distribution device determines the status information of the target power equipment as a start-up state; if the current data in the power consumption data is less than or equal to the preset threshold, the power distribution device determines the status information of the target power equipment as a stop state.

[0039] In this embodiment, the power distribution device detects the magnitude relationship between the current value in the three-phase AC circuit and the preset threshold value to intuitively and accurately determine the state of the target electrical equipment. The preset threshold value can be set to 0 to quickly respond to the current change when the target electrical equipment is switched on and off.

[0040] For example, if the current data at the current sampling time in the power consumption data is greater than the preset threshold value 0, it means that the target power-consuming device has been powered on and is running, and the power distribution device determines the state information of the target power-consuming device at the current sampling time as the startup state. Similarly, if the current data at the current sampling time in the power consumption data is less than or equal to the preset threshold value 0, it means that the target power-consuming device is disconnected and is not running, and the power distribution device determines the state information of the target power-consuming device at the current sampling time as the stop state.

[0041] Furthermore, as a refinement and extension of the specific implementation methods of the above-mentioned embodiments, in order to fully illustrate the specific implementation process of this embodiment, the power distribution device adjusts the steps of the power switch module according to the power consumption data and the parameter protection rules, specifically including: if the current data in the power consumption data is greater than the preset threshold, the power distribution device determines the operating parameters of the target power equipment according to the power consumption data according to the preset rules; if the operating parameters meet the parameter protection rules, the power distribution device controls the power switch module to disconnect, and determines the protection action information according to the operating parameters that meet the parameter protection rules, and sends the protection action information to the server.

[0042] In this embodiment, the power distribution device detects abnormal conditions during the operation of the target power equipment through parameter protection rules, and responds quickly when an abnormality occurs in the target power equipment, promptly controlling the power switch module to cut off the three-phase AC circuit to disconnect the power supply of the target power equipment, prevent equipment loss, and reduce the risk of fire and other hazards. At the same time, the power distribution device feeds back the protection action information to the server, so that the server sends the protection action information to the user end, so that the staff can promptly understand the fault condition of the target power equipment and repair it in time, thereby realizing remote monitoring.

[0043] Exemplarily, if the current data in the power consumption data is greater than a preset threshold, the power distribution device determines that the target power consumption equipment is in the startup state. At this time, the power distribution device calculates the operating parameters of the target power consumption equipment according to the power consumption data according to the pre-stored rules. For example, the operating parameters are calculated based on the voltage and current in the three-phase AC circuit to reflect the operating conditions of the target power consumption equipment. The operating parameters may include three-phase imbalance rate, three-phase voltage loss (the voltage of one or all phases in the three-phase AC circuit is lower than the critical voltage), power, three-phase current missing (the current of one or all phases in the three-phase AC circuit is lower than the critical current), etc.

[0044] Furthermore, if the operating parameters comply with the parameter protection rules, it indicates that the target electrical equipment is operating abnormally. At this time, the power distribution device immediately controls the power switch module to disconnect and cut off the three-phase AC circuit to disconnect the power supply of the target electrical equipment to prevent accidents.

[0045] At the same time, the distribution device determines the protection action information according to the operating parameters that meet the parameter protection rules, for example, three-phase imbalance, detection B missing item. And send the protection action information to the server, so that the server sends it to the user end, so that the staff can remotely analyze and locate the fault problem, so as to repair the fault in time.

[0046] In one embodiment, the electric energy monitoring method also includes: the distribution device determines the target sub-rule corresponding to the operating parameter according to the preset rule corresponding to the operating parameter; if the operating parameter at the current sampling moment is greater than the parameter threshold of the target sub-rule, the distribution device determines the target time according to the current sampling moment and the target duration of the target sub-rule; if the operating parameters corresponding to each sampling moment between the current sampling moment and the target moment are greater than the parameter threshold of the target sub-rule, the distribution device determines that the operating parameter complies with the parameter protection rule.

[0047] The parameter protection rule includes multiple sub-rules, and the sub-rules include parameter thresholds and target durations.

[0048] In this example, the parameter protection rule sets a target duration to avoid accidental triggering of protection actions on target electrical equipment due to momentary fluctuations or short-term abnormal conditions. The power switch module is only disconnected when the abnormal condition lasts for a certain period of time to improve the stability and reliability of abnormal protection of the power distribution device.

[0049] Exemplarily, the sub-rule is set corresponding to the preset rule, and the power distribution device determines the target sub-rule corresponding to the operating parameter from among the multiple sub-rules included in the parameter protection rule according to the preset rule used when obtaining the operating parameter. For example, after the three-phase unbalance rate as the operating parameter is obtained according to the three-phase current or three-phase voltage of the three-phase AC circuit, the target sub-rule corresponding to the three-phase unbalance rate is found in the parameter protection rule, such as the target sub-rule corresponding to the three-phase unbalance rate includes a three-phase unbalance rate threshold of 20% and a delayed action time (target duration) of 6 seconds.

[0050] Furthermore, if the operating parameter at the current sampling moment is greater than the parameter threshold of the target sub-rule, the operating parameter is continuously greater than the parameter threshold of the target sub-rule within the target duration of the target sub-rule after the current sampling moment. If so, the power distribution device determines that the operating parameter complies with the parameter protection rule, thereby detecting abnormal operation of the target electrical equipment.

[0051] Step 106: The power distribution device sends the power usage data and status information to the server, so that the server stores the power usage data and status information.

[0052] In this embodiment, the power distribution device sends the power consumption data and status information of the target power-consuming equipment to the server, which centrally manages the power consumption data and status information to ensure the integrity and continuity of the data for user-side query and facilitates long-term data analysis and trend research.

[0053] Further, as a refinement and extension of the specific implementation methods of the above-mentioned embodiments, in order to fully illustrate the specific implementation process of this embodiment, the step of the distribution device sending the power consumption data and status information to the server includes: if the current data in the power consumption data is greater than the preset threshold at each sampling moment within the first preset sampling period, the distribution device sends the power consumption data and status information of the last sampling moment in the first preset sampling period to the server; if in the power consumption data, the current data at the current sampling moment is greater than the preset threshold, and the current data at the previous sampling moment is less than or equal to the preset threshold, the distribution device sends the power consumption data and status information at the current sampling moment to the server; if in the power consumption data, the current data at the current sampling moment is less than or equal to the preset threshold, and the current data at the previous sampling moment is greater than the preset threshold, the distribution device sends the power consumption data and status information at the current sampling moment to the server.

[0054] In this example, the power distribution device distinguishes the methods of sending power consumption data and status information to the server according to the specific operating conditions of the target power-consuming equipment, transmits data efficiently, avoids continuous transmission of large amounts of data, and reduces network occupancy and data storage pressure.

[0055] For example, if the current data in the power consumption data is greater than the preset threshold at each sampling time within the first preset sampling period, the power distribution device determines that the target power consumption device is in a normal operating state, and sends the power consumption data and status information at the last sampling time in the first preset sampling period to the server, so that the power distribution device sends the power consumption and operating status of the target power consumption device to the server according to the first preset sampling period during the normal operation of the target power consumption device, thereby reducing unnecessary resource consumption. The first preset sampling period can be set to 60s.

[0056] Furthermore, if the power distribution device detects that the power supply of the target power equipment is turned on or off, that is, the state of the target power equipment has changed, it will immediately send the state information and power consumption data of the target power equipment at the time of change to the server, so that the server can detect all state changes of the target power equipment based on the state information received successively, thereby sending the changes in the state of the target power equipment to the user end and providing timely feedback to the staff.

[0057] Exemplarily, if the current data at the current sampling moment is greater than the preset threshold, and the current data at the previous sampling moment is less than or equal to the preset threshold, it means that the target power-consuming device is powered on at the current sampling moment, and the current sampling moment is the moment of change from the stopped state to the started state, and the power distribution device sends the power consumption data and status information at the current sampling moment to the server. Similarly, if the current data at the current sampling moment is less than or equal to the preset threshold, and the current data at the previous sampling moment is greater than the preset threshold, it means that the target power-consuming device is powered off at the current sampling moment, and the current sampling moment is the moment of change from the started state to the stopped state, and the power distribution device sends the power consumption data and status information at the current sampling moment to the server.

[0058] Step 107: The server receives and stores the power consumption data and status information sent by the power distribution device.

[0059] In this embodiment, the server saves the power usage data and status information sent by the power distribution device according to the device information corresponding to the power usage data and status information, so that the device information and its corresponding power usage data and status information are associated in the server.

[0060] In one embodiment, the power monitoring method also includes: if the status information currently received by the server is different from the status information last received, the server determines the status change information based on the currently received status information and the last received status information, and sends the status change information to the user end so that the user end displays the status change information.

[0061] In this instance, the server detects all status changes of the target electrical equipment based on the currently received status information and the last received status information, and sends the status changes of the target electrical equipment to the user end in a timely manner, so that the user can remotely monitor the start and stop status of the target electrical equipment in real time without having to check on site.

[0062] For example, if the status information currently received by the server is the startup status, and the status information last received is the stop status, the server determines the status change information as "at time XX, the target power-consuming device changes from the stop status to the startup status." Similarly, if the status information currently received by the server is the stop status, and the status information last received is the startup status, the server determines the status change information as "at time XX, the target power-consuming device changes from the startup status to the stop status."

[0063] In one embodiment, the electric energy monitoring method also includes: if the server does not receive status information sent by the distribution device within a preset time after sending a control instruction to the distribution device, the server determines abnormal operation information and sends the abnormal operation information to the user end so that the user end displays the abnormal operation information.

[0064] In this embodiment, after sending the control instruction to the power distribution device, the server continues to detect whether the power distribution device performs corresponding actions according to the control instruction, provides accurate information to the user, and improves the reliability of remote control.

[0065] Exemplarily, based on step 106, when the state of the target power-consuming device changes, that is, when the power supply of the target power-consuming device is connected or disconnected, the power distribution device will immediately report the state information of the target power-consuming device at the time of change to the server. If the server does not receive the state information sent by the power distribution device within a preset time after sending a control instruction to the power distribution device, it means that the power distribution device has not successfully controlled the power switch module to connect or disconnect the power supply of the target power-consuming device according to the control instruction. The server determines the abnormal operation information according to the control instruction and sends the abnormal operation information to the user end. The user end displays the abnormal operation information to remind the staff to check. For example, if the control instruction is a startup instruction, the abnormal operation information is determined as "the target power-consuming device failed to start."

[0066] In one embodiment, the electric energy monitoring method also includes: the server receives protection action information sent by the distribution device, and sends the protection action information to the user end, so that the user end displays the protection action information; if the server does not receive the status information sent by the distribution device within a preset time after receiving the protection action information, the server determines the protection abnormality information, and sends the protection abnormality information to the user end, so that the user end displays the protection abnormality information.

[0067] In this embodiment, similar to the server detecting whether the power distribution device performs corresponding actions according to the control instructions, when the server receives the protection action information, it continues to detect whether the power distribution device successfully completes the protection action to avoid accidents, thereby further improving the reliability and effectiveness of remote control.

[0068] Exemplarily, if the server receives protection action information, it means that the power distribution device detects that the target power equipment is operating abnormally, and at this time the power distribution device needs to control the power switch module to disconnect. Based on step 106, when the state of the target power equipment changes, that is, when the power supply of the target power equipment is connected or disconnected, the power distribution device will immediately report the state information of the target power equipment at the time of change to the server. If the server does not receive the state information sent by the power distribution device within a preset time after receiving the protection action information, it means that the power distribution device did not promptly control the power switch module to disconnect the power supply of the target power equipment when the target power equipment was abnormal. The server determines the protection abnormality information and sends the protection abnormality information to the user end. The user end displays the protection abnormality information, and the staff can make repairs in time according to the protection action information and the protection abnormality information.

[0069] It is worth mentioning that if the user receives the status change information sent by the server, but does not send a control instruction or receive a protection action information, it means that the status change of the target electrical equipment is not caused by the control instruction and the protection action. The staff needs to go to the site for further inspection, such as checking whether it is caused by the disconnection of the target electrical equipment's own line.

[0070] In one embodiment, the electric energy monitoring method also includes: in response to the electric energy query instruction and electricity rate period data sent by the user end, the server determines the electric energy information and electricity charge information based on the electricity rate period data and the electricity usage data associated with the device information in the electric energy query instruction, and sends the electric energy information and electricity charge information to the user end so that the user end displays the electric energy information and electricity charge information.

[0071] In this embodiment, users can view the power consumption of different power-consuming devices and the electricity charge information of the power-consuming devices in different time periods through the user-side interface, realize accurate statistics and efficient viewing of electric energy and time period electricity charges, and allow users to grasp the on-site power consumption and historical electricity charges at any time.

[0072] Specifically, users can not only view the relevant data of the running power-consuming equipment in real time on the user-side interface, but also query the historical data of different power-consuming equipment in different historical periods based on the historical data stored in the server, providing users with comprehensive equipment monitoring and management capabilities.

[0073] Exemplarily, the electricity rate period data includes electricity prices corresponding to different periods, and the electricity query instruction may include device information and the query period for which electricity needs to be checked. After receiving the electricity query instruction, the server determines the electricity consumption data in the query period associated with the device information, adds the electricity at each sampling time in the query period, and obtains the accumulated electricity. The electricity data in the query period can also be classified into different rate periods according to the timestamp, and the distribution of electricity consumption in each rate period is calculated, and the data in each rate period is processed to obtain the electricity consumption in each rate period. The electricity consumption in each rate period can also be multiplied by the corresponding electricity unit price to obtain the electricity fee in the rate period. The electricity fees of all rate periods are added together to obtain the total electricity fee in the query period.

[0074] In one embodiment, if Figure 3 As shown, the power distribution device includes a main control communication module, a drive module, a storage module, a power feedback module, an IO module, an energy metering module and an electric switch module.

The main control communication module has data processing capabilities, can determine the status information of the power-consuming equipment, and can communicate with the server. The networking form of the main control communication module can be a 4G module and a WiFi module. The main control communication module realizes the closing and disconnection of the power switch module by controlling the drive module. The power feedback module is used to accurately measure the electrical quantity and monitor the use of electric energy to obtain power consumption data. The power metering module is connected to the power feedback module to obtain the power consumption data measured by the power feedback module. The storage module is used to store the power metering module data and the parameter protection rules issued by the server. The IO module retains the traditional manual operation unit for the power distribution device. The IO module includes a start button, a stop button, a power-on indicator light, and a status indicator light.

[0075] In one embodiment, different teams in a food factory produce two types of products, popcorn chicken and crispy pork, of different brands. Before frying, the two types of products need to switch to different shaping equipment devices in the production line, and the power of the shaping equipment is different. The power monitoring method described in this application is used on site, and the electricity rate period data for this month has been set.

[0076] When producing popcorn chicken, team user A operates through the user interface to input the equipment information, startup instructions and parameter protection rule A1 of the popcorn chicken shaping equipment, and the user end sends the equipment information, startup instructions and parameter protection rule A1 of the popcorn chicken shaping equipment to the server. After receiving the equipment information, startup instructions and parameter protection rule A1 of the popcorn chicken shaping equipment, the server forwards it to the power distribution device. The power distribution device controls the power switch module associated with the popcorn chicken shaping equipment to close according to the startup instructions and the equipment information of the popcorn chicken shaping equipment, regularly reads the power consumption data collected by the electric energy metering module, and periodically reports to the server. If the power distribution device judges that the "missing item" result is obtained according to the parameter protection rule A1 and the three-phase current read by the electric energy metering module, the power distribution device controls the power switch module to disconnect. After the popcorn chicken shaping equipment is powered off, the power distribution device sends the status information of the popcorn chicken shaping equipment to the server, and at the same time sends protection action information, such as: three-phase imbalance, detection B missing item. After receiving the status information, the server determines that the status of the popcorn chicken shaping equipment has changed, determines the status change information, and pushes the status change information and protection action information to the user-side interface for display. After receiving the pushed status change information and protection action information, team user A can restore the disconnected phase B and restart it. When the team completes the task, team user A can send a stop command to the server through the user-side interface. After receiving the stop command, the server forwards it to the power distribution device. The power distribution device controls the power switch module to disconnect according to the stop command. After the power is cut off from the popcorn chicken shaping equipment, the power distribution device sends the status information of the popcorn chicken shaping equipment to the server. After receiving the status information, the server determines that the popcorn chicken shaping equipment has stopped successfully, records the power usage of team user A, and pushes it to the user-side interface for display in combination with the power usage and the rate of electricity.

[0077] When producing crispy pork, team user B operates through the user interface to input the equipment information, startup instructions and parameter protection rule B1 of the crispy pork shaping equipment, and the user end sends the equipment information, startup instructions and parameter protection rule B1 of the crispy pork shaping equipment to the server. After receiving the equipment information, startup instructions and parameter protection rule B1 of the crispy pork shaping equipment, the server forwards it to the power distribution device. The power distribution device controls the power switch module associated with the crispy pork shaping equipment to close according to the startup instructions and the equipment information of the crispy pork shaping equipment, regularly reads the power consumption data collected by the electric energy metering module, and periodically reports it to the server. If the power read by the power distribution device according to the parameter protection rule B1 and the electric energy metering module exceeds the power threshold set by the parameter protection rule B1, it is judged that the "overload" result is obtained, and the power distribution device controls the power switch module to disconnect. After the power-off of the crispy pork shaping equipment is completed, the power distribution device sends the status information of the crispy pork shaping equipment to the server, and at the same time sends protection action information, such as: power overload. After receiving the status information, the server determines that the status of the crispy meat shaping equipment has changed, determines the status change information, and pushes the status change information and protection action information to the user-side interface for display. After receiving the status change information and protection action information, team user B can perform corresponding processing and restart. When the team completes the task, team user B can send a stop command to the server through the user-side interface. After receiving the stop command, the server forwards it to the power distribution device. The power distribution device controls the power switch module to disconnect according to the stop command. After the power is cut off from the crispy meat shaping equipment, the power distribution device sends the status information of the crispy meat shaping equipment to the server. After receiving the status information, the server determines that the crispy meat shaping equipment has stopped successfully, records the power usage of team user B, and pushes it to the user-side interface for display in combination with the power usage and the rate electricity fee.
