[0002] A photovoltaic module control device (such as a photovoltaic module rapid shutdown device, etc.) is an important part of a photovoltaic power distribution system, mainly used to control the power supply output of photovoltaic modules. Thus, when there are safety problems or safety failures in the photovoltaic power distribution system, for example, when the output voltage and temperature of the photovoltaic modules in the photovoltaic power distribution system are abnormal, a fire breaks out, etc., the photovoltaic module control device can control the photovoltaic modules to respond quickly to stop the normal output of electrical energy from the photovoltaic modules and achieve rapid shutdown.

[0045] To make the technical solutions and beneficial effects of the embodiments of the present application more obvious and understandable, the following provides a detailed description by listing specific embodiments. Among them, the drawings are not necessarily drawn to scale, and local features can be enlarged or reduced to more clearly show the details of the local features; unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which the embodiments of the present application belong.

[0046] It should be noted that the terms "first", "second", etc. may be used in this document to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. When describing the "first", it does not necessarily mean that the "second" exists; and when discussing the "second", it does not indicate that the "first" necessarily exists in this application. The singular forms of "a", "an", and "the" may also be intended to include the plural forms, unless the context clearly indicates otherwise. The term "comprising" is used to determine the existence of the features included, but does not exclude the existence or addition of one or more other features. The term "and / or" includes any and all combinations of the related listed items. The meaning of the term "plural" is two or more.

[0047] This specification provides method operation steps such as in the embodiments or flowcharts, but may include more or fewer operation steps based on routine or non-creative labor. The step order listed in the embodiments is only one way among the execution orders of numerous steps and does not represent the only execution order. When the actual device, system, or server product is executed, it can be executed in the order shown in the embodiments or the drawings or in parallel (for example, in an environment with parallel processors or multi-threaded processing).

[0048] Such as Figure 1As shown in the figure, in Solution 1 of the photovoltaic module control device 200 according to an embodiment of the present application, the photovoltaic module control device 200 may include a bypass module 10, a controller 20, a voltage detection circuit 30, and a temperature detection circuit 40. The bypass module 10 may be connected in parallel with the photovoltaic module 300 and may be configured to be turned on or off under the control of a bypass control signal ctr, so that the photovoltaic module 300 is bypassed or normally powered. For example, the voltage input terminal of the bypass module 10 may be connected to the positive electrode PV+ of the photovoltaic module 300, and the voltage output terminal of the bypass module 10 may be connected to the negative electrode PV- of the photovoltaic module 300. When the bypass module 10 is turned on under the control of the bypass control signal ctr, the photovoltaic module 300 is bypassed, that is, the output voltage between the positive electrode PV+ and the negative electrode PV- of the photovoltaic module 300 depends on the voltage difference between the voltage input terminal and the voltage output terminal of the bypass module 10. Therefore, the photovoltaic module 300 can be regarded as being turned off, and the normal power supply output is turned off. Conversely, when the bypass module 10 is turned off under the control of the bypass control signal ctr, the photovoltaic module 300 can be normally powered. The bypass module 10 may include a controllable semiconductor switch device. For example, the controllable semiconductor switch device may include at least one of devices such as BJT (bipolar junction transistor), SCR (silicon controlled rectifier), GTO (gate turn-off thyristor), MOSFET (metal oxide semiconductor field effect transistor, simply referred to as MOS transistor), IGBT (insulated gate bipolar transistor), MCT (MOS controlled thyristor), and SIT (static induction transistor). In this way, it can be turned on or off under the control of a control signal to achieve controllable transmission of the signal.

[0049] The voltage detection circuit 30 may be configured to obtain the voltage vol output by the photovoltaic module 300 and output it to the controller 20. The temperature detection circuit 40 may be configured to obtain the temperature temp of the photovoltaic module 300 and output it to the controller 20. The controller 20 may be configured to determine and output a bypass control signal ctr according to the voltage vol and the temperature temp to control the on or off of the bypass module 10. Therefore, the controller 20 can achieve local control of the power generation of the photovoltaic module 300. When the photovoltaic module 300 generates power, the light intensity and the temperature of the battery panel will affect the battery panel current. Within a certain range, the stronger the light, the greater the output current, and the higher the temperature, the smaller the output voltage. When the photovoltaic module 300 fails, the photovoltaic curve voltage is very small. Therefore, whether a failure occurs can be judged by the voltage vol obtained by the voltage detection circuit 30 and the temperature temp obtained by the temperature detection circuit 40. If a failure occurs, the controller 20 controls the bypass module to conduct unidirectionally through the bypass control signal ctr, thereby protecting the photovoltaic module 300 and stabilizing the photovoltaic string power distribution system. Therefore, the single-component status monitoring of the photovoltaic module is realized, and the protection of the photovoltaic module is more accurate.

[0050] The controller 20 may include a communication module through which a remote control signal can be received to achieve remote control of the photovoltaic module 300. For example, when a special situation such as a house fire occurs and it is necessary to remotely control the photovoltaic module 300 to turn off, the controller 20 can receive a remote control signal through the communication module to control the bypass module 10 to conduct, so that the photovoltaic module 300 is bypassed.

[0051] The photovoltaic module 300 may include a plurality of cell units. The positive electrode of each cell unit can be connected to the cathode of a diode, and the negative electrode of the cell unit can be connected to the anode of the diode to form a reverse parallel connection of the diode. By reversely paralleling a diode to each cell unit, a unidirectional power channel can be formed to play a protective role. For example, as Figure 1 shown, the photovoltaic module 300 includes three cell units. The first cell unit is reversely paralleled and connected to the first diode D1, the second cell unit is reversely paralleled and connected to the second diode D2, and the third cell unit is reversely paralleled and connected to the third diode D3. The reversely paralleled diodes can also use other devices with unidirectional conduction functions to play a role in protecting the cell units, and are not limited to using diodes. As the second solution of the photovoltaic module control device 200 according to the embodiment of the present application, the photovoltaic module control device 200 may, in addition to including the components of the first solution, further include a plurality of diodes, and each diode is reversely paralleled and connected to a cell unit of the photovoltaic module 300.

[0052] The photovoltaic string power distribution system 001 may include a photovoltaic module array and a photovoltaic module control device array. The photovoltaic module array may mainly be composed of series and parallel connections of the photovoltaic modules 300. One photovoltaic module 300 or multiple photovoltaic modules 300 can be controlled by a photovoltaic module control device 200 for its power supply output. For example, as Figure 2 shown, the photovoltaic module array may include the 11th photovoltaic module PV11, the 21st photovoltaic module PV21,..., the nmth photovoltaic module PVnm, where there are a total of nm photovoltaic modules 300, and both n and m are natural numbers. Each photovoltaic module 300 corresponds to a photovoltaic module control device 200 one by one. Thus, the photovoltaic module control device array may include the 11th control device 211, the 21st control device 221,..., the nmth control device 2nm, where there are also a total of nm photovoltaic module control devices 200. The photovoltaic string power distribution system 001 can control the power supply output of the photovoltaic module array through the photovoltaic module control device array, and then transmit it to the power system to supply energy to the power system.

[0053] In addition, as Figure 3As shown, the existing photovoltaic module control device, such as a photovoltaic module rapid shutdown device, sends and loads a power line carrier signal onto the cable through a coupling element, and then senses and captures the power line carrier signal returning from the cable through a carrier signal coupling circuit, so as to transmit the power line carrier signal to the controller through a communication unit, realizing the control of the switching device to quickly shut down. Therefore, it accepts control in the form of power line carrier to switch the working state, and its communication unit sends and returns signals through the cable to control and detect the working state of the shutdown device. Therefore, the applicability and flexibility are relatively poor.

[0054] For this reason, Figure 4 The application environment of the photovoltaic management method according to the embodiment of the present application is shown, as Figure 4 shown, this application environment at least includes a control platform 100, a controller 20, and a gateway 400. The control platform 100 and the controller 20 can be communicatively connected through the gateway 400. The communication connection can adopt a wireless or wired connection method, and the wireless connection avoids the complex wiring method of wired, which is more convenient and fast.

[0055] The control platform 100 can send instructions to the controller 20 to configure the working state (such as conduction state or disconnection state) of the bypass module 10 of the photovoltaic module control device 200, set parameters (such as including voltage threshold and temperature threshold, etc.), and query data (such as including the conduction state or disconnection state of the bypass module 10, the voltage output by the photovoltaic module 300, and the temperature of the photovoltaic module, etc.); it can also collect these data reported by the controller 20.

[0056] The control platform 100 can be a terminal, and this terminal can include types of electronic devices such as smartphones, desktop computers, tablet computers, laptop computers, smart speakers, digital assistants, smart wearable devices, vehicle-mounted terminals, smart TVs, and cameras; it can also be software running on the above-mentioned electronic devices, for example, applications, application programs, applets, etc. The operating system running on the electronic device in the embodiment of the present application can include at least one of Android system, IOS system, linux, windows, etc.

[0057] The controller 20 can be an integrated chip integrated with a communication module, or it can also be the above-mentioned terminal.

[0058] In addition, it should be noted that, Figure 4The figure only shows the application environment of a photovoltaic management method. In actual applications, other application environments may also be included. For example, it may include a server, etc. The server can be communicatively connected to the control platform 100 to transmit instructions and / or data. The server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers. It can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, Content Delivery Network (CDN), and big data and artificial intelligence platforms.

[0059] As Figure 4 shown, the controllers 20 in the photovoltaic component control device array also correspondingly form an array. Any number of controllers 20 in the controller array can form a control module. For example, they can form k control modules (the first control module c1, ……, the kth control module ck) in total, where k is a natural number. The k control modules can be communicatively connected to k gateways one by one. For example, the first control module c1 can be composed of p×q photovoltaic component control devices and correspondingly has p×q controllers 20. They can be in the same geographical area, and both p and q are natural numbers. The p×q controllers 20 can be communicatively connected to the first gateway, thereby realizing the communication connection between the first control module c1 and the first gateway. The controller array can be connected to the gateway 400 through a 2.4G self-organizing network. Each gateway can be connected to the control platform 100 through Ethernet or WIFI. Thus, the control platform in the embodiment of the present application can achieve networked intelligent remote monitoring, overcome the defects of poor applicability and flexibility of the existing photovoltaic component control devices, improve the intelligent level, and meet the requirements of the smart Internet of Things.

[0060] Figure 5 It is a schematic flowchart of a photovoltaic management method provided by an embodiment of the present application. This photovoltaic management method can not only be applied to the above-mentioned controller 20, but also be applicable to many Internet of Things, such as multi-photovoltaic micro-inverter systems, intelligent factory motor drives or lighting systems, etc. This photovoltaic management method may include the following steps:

[0061] S100. Obtain working state data; the working state data includes at least one of the voltage vol output by the photovoltaic component 300, the temperature temp of the photovoltaic component 300, the temperature of the photovoltaic component control device 200 connected to the photovoltaic component 300, and the working state of the bypass module 10.

[0062] S200. Control the working state of the bypass module 10 according to the preset alarm enabling condition and the working state data, and obtain the reporting method to report the working state data according to the reporting method. The reporting method includes a preset heartbeat period reporting method or an immediate reporting method.

[0063] In the embodiment of the present application, the working state of the bypass module 10 may include a conducting state and a disconnecting state. When the bypass module 10 is in the conducting state, the photovoltaic component control device 200 corresponds to the "bypass state"; at this time, the photovoltaic component 300 can be regarded as being turned off. When the bypass module 10 is in the disconnecting state, the photovoltaic component control device 200 corresponds to the "non-bypass state"; at this time, the photovoltaic component 300 can be regarded as outputting power normally and generating electricity normally.

[0064] The preset alarm enabling condition can be set according to actual needs. For example, the control platform 100 can be used to send alarm enabling configuration parameters to the controller 20 to configure the preset alarm enabling condition. In an alternative embodiment, the preset alarm enabling condition may include bypass high-voltage alarm enabling and bypass low-voltage alarm enabling in the bypass state, as well as high-voltage alarm enabling, low-voltage alarm enabling, high-temperature alarm enabling, and low-temperature alarm enabling in the non-bypass state.

[0065] The preset heartbeat period reporting method can be to report the working state data according to a preset heartbeat period. The immediate reporting method can be to immediately report the working state data. The reporting object can be the control platform 100, or other devices, such as a server, etc. Reporting according to a preset heartbeat period can be a heartbeat (clock pulse) reporting mechanism structure, and data is reported according to the heartbeat period. The heartbeat period can be set according to actual needs. For example, a heartbeat period can be 180s.

[0066] In the embodiment of the present application, by controlling the working state of the bypass module according to the preset alarm enabling condition and the working state data, it is possible to timely control the conduction and disconnection of the bypass module to turn off the photovoltaic component when the voltage output by the photovoltaic component is too high or too low, the temperature of the photovoltaic component is too high or too low, etc., which simplifies the control logic and overcomes the voltage stress problem and power generation stability problem that occur during the turn-off control process of the series-connected photovoltaic component control device, thereby being able to shorten the turn-off time and improve safety. And by presetting the alarm enabling condition, it is convenient for the control platform to configure the preset alarm enabling condition, so that the control platform can add a platform protection mechanism by turning off and on the alarm enabling, which is convenient for the control platform to monitor and can better ensure the safety of the photovoltaic component control device.

[0067] In an alternative embodiment, in step S200, the working state of the bypass module 10 is controlled according to the preset alarm enabling condition and the working state data, and a reporting method is obtained to report the working state data according to the reporting method, including:

[0068] S211. When the photovoltaic module control device 200 is in the bypass state and both the bypass high-voltage alarm enabling and the bypass low-voltage alarm enabling are enabled, report the current working state data according to the preset heartbeat period, and control the working state of the bypass module 10 according to the voltage vol output by the photovoltaic module 300 and the temperature of the photovoltaic module control device 200 itself;

[0069] S212. When the working state of the bypass module 10 changes, immediately report the current working state data.

[0070] In the embodiment of the present application, when the photovoltaic module control device 200 is in the bypass state, by using the voltage vol output by the photovoltaic module 300 and the temperature of the photovoltaic module control device 200 itself, the control of the working state of the bypass module 10 is realized, the control strategy of the local protection mechanism is realized, and the safety is improved. And this control strategy has nothing to do with whether the control platform 100 configures each enabling in the non-bypass state of the photovoltaic module control device 200, simplifies the control logic, shortens the turn-off time, and also improves the safety. When the working state of the bypass module 10 changes, the change of the bypass state and the non-bypass state of the photovoltaic module control device 200 can be immediately obtained, so as to immediately report the current working state data, so as to notify the control platform 100 in time, etc., so as to make a timely response.

[0071] In an alternative embodiment, in step S211, controlling the working state of the bypass module 10 according to the voltage vol output by the photovoltaic module 300 and the temperature of the photovoltaic module control device 200 itself includes:

[0072] When at least one of the voltage vol output by the photovoltaic module 300 being higher than the bypass high-voltage threshold, the voltage vol output by the photovoltaic module 300 being lower than the bypass low-voltage threshold, and the temperature of the photovoltaic module control device 200 itself being higher than its own high-temperature threshold is satisfied, control the bypass module 10 to disconnect, and when the temperature of the photovoltaic module control device 200 itself returns below its own high-temperature threshold, start waiting and control the bypass module 10 to resume conduction after waiting for a preset time.

[0073] Figure 6A specific example of the control strategy of the local protection mechanism according to the embodiments of the present application is shown. The bypass high-voltage threshold, the bypass low-voltage threshold, and the self-high-temperature threshold can all be set according to actual requirements, and specific threshold parameters can be configured by the control platform 100 to send to the controller 20. For example, the bypass high-voltage threshold can be set to 2.2V, the bypass low-voltage threshold can be set to 1.2V, and the self-high-temperature threshold can be set to 150°C. In the embodiments of the present application, each threshold is used as the dividing point of each range. On the premise that the divided ranges do not overlap, it can be used as the endpoint value of any range in each range. The determination of the endpoint values of other ranges in the embodiments of the present application is similar and will not be elaborated here.

[0074] The preset waiting time can be set according to actual requirements. For example, the preset time can be set to 1 minute. As a specific example, the photovoltaic module control device 200 detects its own temperature and voltage (the voltage vol output by the photovoltaic module 300 in the bypass state can be the voltage of the photovoltaic module control device 200 itself, that is, the voltage between the voltage input terminal and the voltage output terminal of the bypass module 10). When the temperature is lower than the self-high-temperature threshold and the voltage is lower than the bypass high-voltage threshold and higher than the bypass low-voltage threshold, the photovoltaic module control device 200 maintains the "bypass state" and reports data (the current working state data) according to the preset heartbeat period; when the temperature is higher than the self-high-temperature threshold, the voltage is higher than the bypass high-voltage threshold, or the voltage is lower than the bypass low-voltage threshold, the controller 20 controls the bypass module 10 to disconnect, and the photovoltaic module control device 200 automatically disconnects the bypass and enters the "non-bypass state"; then continuously detects the temperature. When the temperature returns below the self-high-temperature threshold, wait for 1 minute to control the bypass module 10 to conduct again, and the photovoltaic module control device 200 enters the "bypass state"; then continue to monitor the temperature and voltage. And when the working state of the bypass module 10 changes, it will immediately report data (the current working state data). In the embodiments of the present application, the controller 20 can generate and output a bypass control signal ctr to the bypass module 10 by itself, so that the conduction and disconnection of the bypass module 10 can be controlled through the bypass control signal ctr.

[0075] In the embodiments of the present application, the preset alarm enabling condition may be that both the bypass high-voltage alarm enabling and the bypass low-voltage alarm enabling described above are enabled, or either one of them may be enabled and the other is disabled. When either one is enabled and the other is disabled, the conditions of the judgment steps included in step S211 may be adjusted accordingly. For example, when the bypass high-voltage alarm enabling is enabled and the bypass low-voltage alarm enabling is disabled, the conditions of the judgment steps included in step S211 may be correspondingly replaced with: in the case where at least one of the voltage vol output by the photovoltaic module 300 being higher than the bypass high-voltage threshold and the temperature of the photovoltaic module control device 200 being higher than its own high-temperature threshold is satisfied. Other cases are similar and will not be elaborated here.

[0076] In an alternative embodiment, in step S200, the working state of the bypass module 10 is controlled according to the preset alarm enabling condition and the working state data, and a reporting method is obtained to report the working state data according to the reporting method, including:

[0077] S221. When the photovoltaic module control device 200 is in a non-bypass state and the high-voltage alarm enabling, low-voltage alarm enabling, high-temperature alarm enabling, and low-temperature alarm enabling are all in effect, determine the reporting method according to the voltage vol output by the photovoltaic module 300 and the temperature of the photovoltaic module 300, and report the current working state data according to the reporting method;

[0078] S222. When the working state of the bypass module 10 changes, immediately report the current working state data.

[0079] In the embodiments of the present application, by reporting data in a timely manner according to the preset heartbeat period when the photovoltaic module control device 200 is in a non-bypass state, real-time monitoring of the voltage vol output by the photovoltaic module 300 and the temperature of the photovoltaic module 300 is achieved, thereby realizing the monitoring of the normal power supply output of the photovoltaic module 300 by the control platform and improving the safety. When the working state of the bypass module 10 changes, the current working state data can also be immediately reported to notify the control platform 100, etc. in a timely manner so as to make a timely response.

[0080] In an alternative embodiment, in step S221, determining the reporting method according to the voltage vol output by the photovoltaic module 300 and the temperature of the photovoltaic module 300, and reporting the current working state data according to the reporting method, includes:

[0081] In the case where at least one of the voltage vol output by the photovoltaic module 300 being higher than the high-voltage threshold, the voltage vol output by the photovoltaic module 300 being lower than the low-voltage threshold, the temperature temp of the photovoltaic module 300 being higher than the high-temperature threshold, and the temperature temp of the photovoltaic module 300 being lower than the low-temperature threshold is satisfied, immediately report the current working state data;

[0082] When the voltage vol output by the photovoltaic module 300 is lower than the high-voltage threshold and higher than the low-voltage threshold, and the temperature temp of the photovoltaic module 300 is lower than the high-temperature threshold and higher than the low-temperature threshold, the current working status data is reported according to a preset heartbeat period.

[0083] Figure 7 A specific example of the control strategy of the control platform according to the embodiments of the present application is shown. The high-voltage threshold, the low-voltage threshold, the high-temperature threshold, and the low-temperature threshold can all be set according to actual needs, and can all be configured by the control platform 100 to send specific threshold parameters to the controller 20. For example, the high-voltage threshold can be set to 55V, the low-voltage threshold can be set to 15V, the high-temperature threshold can be set to 150 °C, and the low-temperature threshold can be set to -10 °C. In the embodiments of the present application, the frequency of immediately reporting data can be set according to actual needs to avoid frequent alarms. For example, for the immediate reporting of data caused by the same reason (such as the immediate reporting of data caused by the voltage vol output by the photovoltaic module 300 being higher than the high-voltage threshold), it can be set to report once every 1 minute.

[0084] As a specific example, when the photovoltaic module control device 200 and the control platform 100 are turned on, the photovoltaic module control device 200 starts to work. At this time, the photovoltaic module control device 200 can be in a "non-bypass state". In the non-bypass state, the above steps S221 to S222 can be performed. For example, first, the photovoltaic module control device 200 detects whether the voltage and temperature exceed the high-voltage threshold and the high-temperature threshold. If they exceed, the controller 20 immediately reports the data to the control platform 100; if not, the controller 20 reports the data at a normal preset heartbeat period. When the control platform 100 issues an instruction to change the bypass state of the photovoltaic module control device 200, such as a change from the "non-bypass state" to the "bypass state", the controller 20 immediately reports the data to the control platform 100. In the bypass state, the above steps S211 to S212 can be performed to enter the local processing mechanism. For example, in the local sampling over-temperature or over-voltage protection mechanism, if the photovoltaic module control device 200 detects that the voltage and its own temperature exceed the bypass high-voltage threshold and its own high-temperature threshold, the controller 20 controls the bypass module 10 to disconnect, so that the photovoltaic module control device 200 switches to the "non-bypass state", and immediately uploads the data to the control platform 100. And continuously detect its own temperature. When it is lower than its own high-temperature threshold, after waiting for 1 minute, the controller 20 controls the bypass module 10 to conduct again, so that the photovoltaic module control device 200 returns to the "bypass state", and at this time, the data is also immediately uploaded to the control platform 100.

[0085] In an alternative embodiment, in step S200, the working state of the bypass module 10 is controlled according to the preset alarm enabling condition and the working state data, and a reporting method is obtained to report the working state data according to the reporting method, further including:

[0086] In response to the received bypass switching instruction, control the working state of the bypass module 10.

[0087] In the embodiment of the present application, as Figure 8 shown, if the controller 20 receives a bypass switching instruction sent by the control platform 100 through the gateway 400 when the photovoltaic module control device 200 is in the "non-bypass state", the controller 20 can control the bypass module 10 to conduct, so that the photovoltaic module control device 200 is switched to the "bypass state". If the controller 20 receives a bypass switching instruction sent by the control platform 100 through the gateway 400 when the photovoltaic module control device 200 is in the "bypass state", the controller 20 can control the bypass module 10 to disconnect, so that the photovoltaic module control device 200 is switched to the "non-bypass state".

[0088] In an alternative embodiment, the photovoltaic management method further includes the following steps:

[0089] S300. In response to the received setting parameter instruction, perform parameter setting; the parameters include at least one of bypass high-voltage alarm enabling, bypass low-voltage alarm enabling, high-voltage alarm enabling, low-voltage alarm enabling, high-temperature alarm enabling, low-temperature alarm enabling, preset heartbeat period, bypass high-voltage threshold, bypass low-voltage threshold, self-high-temperature threshold, high-voltage threshold, low-voltage threshold, high-temperature threshold and low-temperature threshold; and / or

[0090] S400. In response to the received query instruction, immediately report the current working state data.

[0091] In the embodiment of the present application, the above bypass switching instruction, setting parameter instruction and query instruction can all be sent by the control platform 100 through the gateway 400, or can be sent by a server or the like. By using the network platform control of the gateway in the embodiment of the present application, the working state of the photovoltaic module control device can be remotely detected and changed. Compared with the existing single control framework or short-range local wired control, the network platform control is more convenient and intelligent. And the network platform control is more conducive to meeting the intelligent requirements of large-scale photovoltaic power generation with tens of millions of components.

[0092] As Figure 9As shown in the figure, the reporting mechanism can be divided into four cases: First, when the photovoltaic module control device 200 is operating normally (in both non-bypass and bypass states), the reported data is reported according to a preset heartbeat cycle (for example, a heartbeat cycle can be set to 180 s); Second, when the on / off state of the bypass module 10 changes, the current working state data is reported immediately, including the change data of the working state of the bypass module 10; Third, when an alarm is triggered, the data is reported immediately, and for the same triggering condition, it is not reported repeatedly within one minute; Fourth, when the platform issues a query instruction, the query data is reported immediately. It can be seen that when the photovoltaic module control device 200 is operating normally, the reporting data cycle is reported according to the heartbeat cycle; while in the three cases of the on / off change of the bypass module 10, alarm triggering, and the platform issuing a query instruction, the reporting data cycle is immediate (such as a pulse interval).

[0093] The photovoltaic management method of the embodiment of the present application can provide a safe and stable intelligent control technology for the photovoltaic module control device, ensuring the safe and effective operation of the photovoltaic array. By monitoring the voltage output by the photovoltaic module, the temperature of the photovoltaic module, and the temperature of the photovoltaic module control device itself and the bypass module connected to the photovoltaic module, the safety of the photovoltaic string power distribution system is ensured, and the stable and effective power generation of the photovoltaic array is guaranteed. And combined with the alarm mechanism, the detected data is reported to the platform logically, providing a convenient detection method for operators and providing stable and safe protection measures for photovoltaic grid power generation.

[0094] Currently, there are two types of photovoltaic grid-connected power generation: 1) Photovoltaic micro-inversion: The photovoltaic array usually consists of several components, the voltage of the photovoltaic array is relatively low, and the inversion power is relatively small, which is suitable for household grid-connected power consumption. 2) Photovoltaic medium-high power inversion: The photovoltaic array is composed of multiple photovoltaic modules connected in series and parallel, the voltage is relatively high, and the electric energy enters the DC cabinet through the busbar box and then enters the inversion system, and the inversion power is relatively large, which is suitable for factory and enterprise power consumption. And no matter which type of photovoltaic grid-connected power generation, the requirements for the photovoltaic system protection mechanism are to reduce costs and power consumption and improve the output ratio, etc. The embodiment of the present application not only effectively overcomes the above defects, but also simplifies the complex control logic of the existing disconnector, optimizes the operation platform, and can manage the power generation of the photovoltaic array more reasonably.

[0095] The embodiments of the present application adopt a two - layer protection mechanism: one is the temperature and voltage detection protection mechanism local to the photovoltaic component control device; the other is the alarm protection mechanism for setting the "bypass state" and "non - bypass state" of the photovoltaic component control device on the control platform, which improves the safety and reliability of the photovoltaic component control device. And compared with the single local voltage and current protection of the existing disconnector and the lack of a platform control architecture, the two - layer protection mechanism is more comprehensive and effective, and further ensures the safety and reliability of the photovoltaic component control device. The embodiments of the present application apply Internet of Things technology to the modular control of the photovoltaic component control device, realizing intelligent remote monitoring of the photovoltaic component status, and can remotely and effectively control the working state of the photovoltaic component in case of emergencies, meeting the safety - regulation design standards.

[0096] Therefore, the photovoltaic management method of the embodiments of the present application comprehensively considers the characteristics of the bypass state of the photovoltaic component control device, the characteristics of the photovoltaic array, and the requirements of the intelligent Internet of Things, constructs an intelligent control system for the photovoltaic component control device, and realizes simple control logic, a multi - layer protection mechanism, and an intelligent control network platform. Multiple features improve the product competitiveness of the photovoltaic component control device.
