Description
Technical Field
The present invention relates to the field of electronic communications technologies, and in particular, to a method and a system for setting module attributes of a monitoring module.
Background
In a photovoltaic solar power station, a plurality of converging monitoring units, namely photovoltaic converging monitoring modules, are generally required to monitor key information such as power generation current, converging voltage, alarm state and the like of a photovoltaic solar panel in real time so as to ensure the normal operation of the power station. In actual engineering, the photovoltaic confluence monitoring modules are basically connected in series by using an RS485 bus, and then are communicated with a local upper computer through an industry standard MODBUS-RTU communication protocol. As is well known, when the MODBUS-RTU communicates on the serial bus, each serial device must be configured with a unique address (e.g. 1-244) on the bus, and the serial device can receive and send normally only when the serial properties of the device, such as baud rate, are consistent, otherwise, the serial device is a black box relative to the host computer. However, in summary of the current equipment networking installation process, the photovoltaic busbar monitoring module is usually required to be installed in a busbar box before shipment, and the busbar box usually has a certain weight and volume because other primary power equipment can be wrapped. In construction, a power station usually has hundreds to thousands of junction boxes, and addresses of photovoltaic junction monitoring module devices in the junction boxes are set in advance, so that the junction boxes are extremely inconvenient in the actual installation and use processes,
in addition, solar power plants are often remote, and during construction, the handling is troublesome, and especially, the parameter modification of the power supply of the equipment before the formal use of the equipment is also troublesome. Therefore, the solar panel is used for supplying power after the junction box is installed on a construction site, and then a professional engineering technician uniformly modifies parameters according to user habits. However, in a solar power plant, hundreds to thousands of "photovoltaic confluence monitoring modules" are generally used according to the size of the solar power plant, and the solar power plant is scattered (the distance between two modules is different from 100 meters to 1000 meters), and the solar photovoltaic panel is installed relatively short, so that the solar power plant is in a high-pressure working environment, and engineering personnel cannot easily pass through, therefore, the working efficiency of engineering technicians is very low and the solar power plant is very unsafe.

Detailed Description
For a clearer understanding of technical features, objects and effects of the present invention, a detailed description of embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in fig. 1, in a first embodiment of a method for setting module attributes of a monitoring module according to the present invention, the method is applicable to a plurality of interconnected monitoring modules connected to the same setting host, and includes the steps of: s1, any one of a plurality of monitoring modules is triggered to be switched from a default state to a trigger state; s2, the first monitoring module in the current triggering state receives module attribute data information broadcasted by the setting host according to a first preset rule, and when the current response state identification of the first monitoring module is a first state identification, the module attribute of the first monitoring module is set according to the module attribute data information; s3, the first monitoring module modifies the current response state identifier of the first monitoring module into a second state identifier after the module attribute is set, and generates a corresponding response instruction; s4, the host is set to receive a response instruction, and module attribute data information is updated according to a second preset rule; s5, triggering another monitoring module into a triggering state according to a third preset rule, and sequentially executing the steps S2 to S4; and S6, stopping broadcasting the module attribute data information when the setting host judges that the module attributes of the monitoring modules are all set according to the response instruction.
That is, the plurality of monitoring modules are connected to the setting host through a bus, that is, the plurality of monitoring modules can be connected to each other through a bus and to the setting host, and before the address setting is performed on the monitoring modules, the monitoring modules on the same bus are all set to a default state. When the monitoring module is set with the module attributes such as the module address of the monitoring module, any one of the monitoring modules is triggered to enter the triggering state from the default state. And defining the monitoring module in the current trigger state as a first monitoring module, wherein the first monitoring module receives module attribute data information broadcasted by the setting host according to a first preset rule. It can be understood that when the detection module address is set, before or after triggering the first monitoring module, the first monitoring module connected with the setting host broadcasts the module attribute data information, and after receiving the module attribute data information, the first monitoring module connected with the setting host acquires the current response state identifier inside the monitoring module to judge, and when the current response state identifier inside the monitoring module is the first state identifier, the first monitoring module responds to the received module attribute data, and sets the corresponding module attribute according to the module attribute data. After the module attribute setting is completed, the monitoring module modifies the current response identifier into a second state identifier and generates a corresponding response instruction for completing the module attribute setting. The response instructions may be broadcast on the same bus in broadcast form. After the setting host receives the response instruction, the module attribute data information is updated according to a certain rule, namely a second preset rule, so that the module attribute of the next monitoring module is set. The next monitoring module may be a monitoring module triggered to be in a triggered state according to a third preset rule, and after the next monitoring module is triggered, the setting of the module attribute of the monitoring module is sequentially performed according to the above steps. And sequentially performing, in the process of setting the module attributes of the monitoring modules, stopping broadcasting the module attribute data information when the host receives the response instruction and judges that the module attributes of a plurality of monitoring modules are set according to the received response instruction, namely finishing the setting of the module attributes of the monitoring modules. According to the above process, after each monitoring module is triggered, the module attribute of the monitoring module is set, the module attribute of each monitoring module is different, and the monitoring modules and the corresponding module attribute are in a one-to-one correspondence relationship, so that when the monitoring modules on the same bus are operated, the specific monitoring module can be identified to perform the required operation.
Further, the module attribute data information includes module address information and interface attribute information; in step S2, setting module attributes of the first monitoring module according to the module attribute data information, including: setting the module address of the first monitoring module according to the module address information and setting the interface attribute of the first monitoring module according to the interface attribute information. Specifically, the module attribute of the monitoring module may be defined as module address information of the monitoring module and interface attribute information of the monitoring module, when the monitoring module receives the module attribute information, the module address of the monitoring module is set according to the module address information, and meanwhile, the interface attribute of the monitoring module is set according to the interface attribute information, where the interface attribute may include the baud rate, stop bit and other common characteristics of the interface. It can be understood that, in order to realize the convenience of data transmission on the same bus, the set interface attribute information can be fixed, that is, the interface attributes of all the monitoring modules are set to be the same interface attribute.
On the above basis, in step S4, updating the module attribute data information according to the second preset rule includes: the module address information is updated in an incremental or decremental manner. That is, after confirming that the module attribute of the current monitoring module is set, the setting host may update the module address information in an incremental or decremental manner to obtain updated module attribute data information, and rebroadcast the updated module attribute data information to set the module attribute of the next monitoring module.
As shown in fig. 2, in an embodiment, after the host is set to stop broadcasting the module attribute data information, the following steps are further performed, and S7, the host is set to set the interface attribute of the host according to the interface attribute information. That is, after the setting host determines that the setting of the module attribute of all the monitoring modules is completed, the setting host may set the interface attribute of the setting host to be the same as the interface attribute of the monitoring module, that is, the setting host sets its own interface attribute according to the interface attribute information in the module attribute data information for broadcasting and defining the monitoring module, so as to facilitate the data communication between the setting host and each monitoring module.
As shown in fig. 3, in an embodiment, a module attribute setting method of a monitoring module of the present invention further includes: s0, setting a first triggered second monitoring module as a setting host, and setting a module address of the second monitoring module according to corresponding initial address information. Specifically, any monitoring module may be set as the setting host, that is, it may select the monitoring module that is triggered first, that is, the second monitoring module, to be set as the setting host. When the monitoring module is triggered to set up the host, the monitoring module can firstly set up the module address according to the corresponding initial address information, and simultaneously, the monitoring module starts to broadcast module attribute information data as the set host so as to set up corresponding module attributes of other monitoring modules.
Optionally, on the above basis, the second monitoring module sets a module address thereof according to the corresponding initial address information, including: reading default address information of the second monitoring module to set a module address of the second monitoring module according to the default address information of the second monitoring module; or receiving a user instruction to acquire initial address information and set a module address of the second monitoring module according to the user instruction. That is, in an embodiment, when the second monitoring module is set to set the host, it sets its module address according to the initial address information and may set its module address according to the default address information in the second detection module. In another embodiment, the initial address information may also be determined by the user instruction according to the user instruction received by the second monitoring module, so as to set the address of the second monitoring module.
In one embodiment, in step S6, the setting host determines that the module attributes of the plurality of monitoring modules are all set according to the response instruction includes: starting timing when the host computer is set to receive the response instruction, and judging that the module attributes of the monitoring modules are all set when the next response instruction is not received when the timing time length meets the preset time length; that is, the process of setting the host to receive the response instruction to determine that all the module attributes of the monitoring modules have been set may be to start timing after the host receives the response instruction, to end the current timing after receiving the next response instruction, and to perform new timing. The normal condition is that the monitoring modules are triggered one by one and the module attribute setting is carried out, the host is set to receive response instructions of the corresponding monitoring modules one by one until the response instruction of the last monitoring module is received, after the response instruction is received, the next response instruction can not be received within a longer time, at this time, all the monitoring modules can be judged to have completed the module attribute setting, and the host is set to stop broadcasting module attribute data information, namely, the module attribute setting of the monitoring modules is stopped.
In one embodiment, in step S6, the setting host determines that the module attributes of the plurality of monitoring modules are all set according to the response instruction includes: and the host is set to count the response instructions, and the module attributes of the monitoring modules are judged to be set completely when the count meets the preset condition. The number of the monitoring modules can be obtained, the host is set according to the number of times of obtaining the response instructions, when the number of times of obtaining the response instructions is consistent with the number of the monitoring modules, the host can judge that the monitoring modules all complete the module attribute setting, and the host stops broadcasting the module attribute data information, namely, stops the module attribute setting of the monitoring modules. It is understood that the number of monitoring modules may be set by user instructions, and when the host is set as the second monitoring module, it may reject the second monitoring module into the count of monitoring modules.
In one embodiment, in step S1, the setting host broadcasts module attribute data information according to a first preset rule includes: the host is set to broadcast the module attribute data information according to the first preset interval time. When the host is set to broadcast the module attribute data information, the host can broadcast the module attribute data information at certain intervals. That is, the module attribute data information is broadcast once at intervals to wait for a response instruction confirming whether the monitoring module replies, and if not, the module attribute data information is broadcast once again. It may also broadcast according to a predetermined interval time without actually having a reply instruction, and broadcast according to the same interval time after receiving a response instruction replied by the monitoring module and updating the module attribute data information. The broadcast rule may be preset.
Further, on the above basis, in step S1, the setting host broadcasting the module attribute data information according to the first preset rule further includes: and the host is set to modify the data attribute of the module attribute data information according to the second preset interval time. That is, in some application scenarios, the monitoring modules may be different monitoring modules, that is, the data protocols followed by the monitoring modules are different, the default interface attribute of the obtained monitoring module may be different from the default interface attribute of the setting host, when the setting host broadcasts data according to the default interface attribute, part of the monitoring modules may not receive the data, when the setting host broadcasts the module attribute data information, the interface attribute of the setting host may be modified to be different in sequence, and when the interface attribute of the setting host is updated once, the module attribute data information is broadcast once, and when the interface attribute of the setting host is consistent with the interface attribute of the first monitoring module, the first monitoring module can receive the broadcast information of the setting host and set. And simultaneously, the response instruction of the first monitoring module is returned to the setting host, and when the setting host receives the response instruction to set the module attribute of the next monitoring module, the interface attribute of the setting host is sequentially modified into different interface attributes again according to the same rule, and the process is repeated.
In one embodiment, in step S5, triggering another monitoring module to a triggering state according to a third preset rule includes: after the previous monitoring module is triggered to be in a triggering state, triggering the adjacent other monitoring module to be in a triggering state according to a third preset interval time. That is, the monitoring modules are triggered sequentially at a certain time interval, and the triggering process of the monitoring modules can also be triggered sequentially according to the installation position sequence of the monitoring modules. The ordering of the module addresses of the monitoring modules and the ordering of the installation positions of the monitoring modules can be formed into corresponding relations.
In an embodiment, the monitoring module being in a default state includes the monitoring module being in a powered-down state, and the monitoring module being in a trigger state includes the monitoring module being in a powered-up state; the monitoring modules are powered on, so that the monitoring modules are powered on to enter a powered-on state, namely, the triggering state is corresponding to the powered-on state. The sequential triggering process of the monitoring module is a sequential power-on process of the monitoring module.
In an embodiment, the monitoring module being in a default state includes the monitoring module being in a powered-on state and the state identifier of the monitoring module being a first identifier, the monitoring module being in a triggered state includes the monitoring module being in a powered-on state and the state identifier of the monitoring module being a second identifier. The monitoring module is in a power-on state, a state identifier is arranged in the monitoring module, and the monitoring module is in a default state when the state identifier is a default identifier, namely a first identifier. At this time, the monitoring module does not receive the module attribute data information broadcast by the set host even in the power-on state. Triggering the monitoring module to switch the state identifier of the monitoring module into a second identifier, wherein the monitoring module is still in a power-on state at the moment, can receive the module attribute data information broadcasted by the set host, and judges whether to respond to the module attribute data.
Optionally, the state identification of the monitoring module being the first identification includes the current response state identification of the monitoring module being a default state identification different from the first state identification and the second state identification; the state identification of the monitoring module being the second identification comprises that the current response state identification of the monitoring module is the first state identification or the second state identification, and triggering the monitoring module to be the triggering state comprises that the current response state identification of the monitoring module is the first state identification. The state identifier of the monitoring module may be represented by a current response state identifier of the monitoring module, that is, when the current response state identifier of the monitoring module is a default state identifier different from the first state identifier and the second state identifier, that is, the first identifier corresponding to the state identifier of the monitoring module, so as to confirm that the monitoring module is in the default state. Meanwhile, when the state identifier of the monitoring module is represented by the current response state identifier of the monitoring module, namely when the current response state identifier of the monitoring module is the first state identifier or the second state identifier, namely the second identifier corresponding to the state identifier of the monitoring module, the monitoring module is confirmed to be in a triggering state. When the trigger monitoring module is in a trigger state, the trigger monitoring module can trigger the current response state of the monitoring module to be a first state identifier.
In an embodiment, a method for setting module attribute of a monitoring module according to the present invention further includes: triggering any first monitoring module to generate a first triggering instruction, and setting a host to receive the first triggering instruction to stop broadcasting module attribute data information; that is, in the module attribute setting process of the monitoring module, the module attribute setting process of the whole monitoring module can be ended by triggering any first monitoring module to generate a first triggering instruction.

In an embodiment, the trigger control module 140 includes a power-on control module connected to the power supply module 130 and the monitoring module 120 for controlling the power supply module 130 to power on the monitoring module 120 so that the monitoring module 120 is powered on to enter a trigger state; in another embodiment, the trigger control module 140 is further configured to trigger the state identifier of the monitoring module 120 to switch from the first identifier to the second identifier. Specifically, the trigger control module 140 may trigger the current response state identifier of the monitoring module 120 to be the first state identifier. That is, the plurality of monitoring modules 120 are correspondingly connected with the plurality of monitored devices 150, the host 110 and the plurality of monitoring modules 120 are connected through buses, the triggering control module 140 controls the monitoring modules to trigger, the monitoring modules 120 correspond to the power supply modules 130, and the power supply modules 130 can provide power supply voltages for the monitoring modules 120. The module attribute setting of the monitoring module 120 thereof may be set with reference to the module attribute setting method of the monitoring module described above. And will not be described in detail herein.
In one embodiment, the host 110 includes a host computer or a monitoring module that first enters a trigger state; when the monitoring module is selected as the setting host 110, it may specifically set the module attributes of all the monitoring modules according to the module attributes of the monitoring modules described above.
In one embodiment, as shown in fig. 5, the power supply module 130 is a photovoltaic array, and the monitoring module 120 is a bus monitoring module. The connection between the host 110 and the monitoring module 120 is set to be connected through a serial bus, and the serial port can be an RS485 interface. That is, in solar power distribution engineering, the monitoring module 120 is a junction monitoring module, which is also referred to as a photovoltaic junction monitoring module. The converging monitoring module is used for monitoring the working characteristics of the photovoltaic square matrix, namely the monitored equipment corresponding to the monitoring module is the solar photovoltaic square matrix. Meanwhile, each photovoltaic confluence monitoring module is provided with an independent power supply, the power supply is connected to a nearby solar panel through an independent switch S1, and in the construction process, all the switches S1 are disconnected, namely the photovoltaic confluence monitoring modules are not powered and are in a non-working state. After the construction is completed, the switch S1 needs to be closed one by one to supply power to the photovoltaic confluence monitoring module. It is understood that the power supply module 130 for supplying power to the monitoring module 120 is disposed on the photovoltaic array, and may be understood as supplying power to the monitoring module simultaneously when monitored through the photovoltaic array. In the module attribute setting system of the monitoring module, the specific process of module attribute setting of the converging monitoring module is as follows: after wiring is completed, before the control module is triggered to control switching-on to electrify the confluence monitoring module, the upper computer is used as a setting host, and the upper computer is connected with the confluence monitoring module through a bus. The setting host operates first, the bus monitoring module is not electrified, the setting host broadcasts setting messages, namely module attribute data information, on a bus at certain time intervals, for example, 100ms, and the setting messages comprise serial port attributes such as baud rate and the equipment address needing to be set currently. In order to prevent the serial port attributes of the setting host and the bus monitoring module from being inconsistent, the setting host sets the setting host to be different in serial port attribute such as different baud rates at a certain time interval, for example, 100ms, before the setting host receives the response message, namely, the response instruction. When any one of the bus monitoring modules is powered on in a closing state, the bus monitoring module enters a trigger state, and the response state st of the bus monitoring module is set to 0. Only the bus monitoring module with the response state st of 0 responds to the setting message, and after the response is completed, the response state is modified to be the responded setting message, namely, the response state st=1. In this way, only the new bus monitoring module powered on by closing the switch S1 will respond to the setting message broadcast by the setting host. Meanwhile, it should be noted that when the convergence monitoring module receives the setting message sent by the setting host and can be resolved correctly, the setting host and the serial port attribute of the convergence monitoring module are consistent, and the response to the setting message can be achieved. And the convergence monitoring module modifies the equipment address and the serial port attribute of the local device according to the set message. The bus monitoring module modifies the response state of the local device to be a response set message, namely, the response state st=1, and the response set message is not responded any more next time. After receiving the reply message of the confluence monitoring module, the host changes the device address in the set message into the device address of the next confluence monitoring module, and usually calculates the device address of the next confluence monitoring module according to a certain rule, for example, accumulation 1. And repeatedly setting the device address of the next confluence monitoring module until the setting is completed or the host computer is abnormally exited, setting the host computer to exit the setting mode, and setting the host computer to have serial port attributes unified with the confluence monitoring module. It should be noted that, in the process of triggering the bus monitoring module in sequence, when the setting process is normally finished, it is indicated that all devices on the bus can normally receive and transmit messages. When the setting process is abnormal, the number of the confluence monitoring modules can be conveniently known to be abnormal. In order to increase reliability, the triggering of the bus monitoring module can also be performed by performing state confirmation on the bus monitoring module, that is, the bus monitoring module is not in a triggering state when being powered on, and can be confirmed to be in the triggering state only after the state of the bus monitoring module is set. Therefore, the secondary setting after the equipment is restarted and powered on can be avoided.
It is to be understood that the above examples only represent preferred embodiments of the present invention, which are described in more detail and are not to be construed as limiting the scope of the invention; it should be noted that, for a person skilled in the art, the above technical features can be freely combined, and several variations and modifications can be made without departing from the scope of the invention; therefore, all changes and modifications that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
