[0001] The present invention relates to the technical field of data non-disturbance switching, in particular to a method for data non-disturbance switching of a temporary chimney CEMS of a thermal power unit and an industrial control computer. Background Art

[0002] As one of the important power generation equipment in my country, the environmental emission issues of thermal power units have always attracted widespread attention. In order to monitor and control the environmental emissions of the units, CEMS (Continuous Emission Monitoring System) is widely used in thermal power plants.

[0003] However, in some cases, such as the temporary installation or modification of a unit chimney, CEMS access may be affected, resulting in interruptions in environmental data and affecting the assessment of environmental indicators. Therefore, it is of great significance to develop a method that can achieve online CEMS installation and data switching without disruption while saving modification costs.

[0004] There are currently some technical solutions related to CEMS systems, such as using supervisory software to remotely monitor CEMS systems and using intelligent algorithms to optimize CEMS data processing. However, there is currently no mature solution for the installation of temporary chimneys and the problem of non-disruptive data switching. Summary of the Invention

Some simplifications or omissions may be made in this section and the abstract and title of this application to avoid obscuring the purpose of this section, the abstract and the title of the invention, and such simplifications or omissions should not be used to limit the scope of the present invention.

[0006] In view of the above existing problems, the present invention is proposed.

[0007] Therefore, the present invention provides a method for non-disruptive switching of temporary chimney CEMS and industrial computer data of thermal power units, which can solve the traditional problem of inaccurate or unavailable monitoring data due to the inability to use the chimney CEMS equipment and industrial computer data normally during the shutdown and maintenance of thermal power units.

[0008] To solve the above technical problems, the present invention provides the following technical solutions: a method for non-disruptive switching of data between a temporary chimney CEMS and an industrial computer of a thermal power unit, comprising:

[0009] Connect the temporary chimney CEMS equipment to the distributor and into the equipment module;

[0010] Use the idle slave IPC of the standby unit to configure the environmental protection parameters of the master IPC of the host unit;

[0011] After the main chimney of the host unit is switched to the temporary chimney, the CEMS system is connected to achieve disturbance-free switching.

[0012] As a preferred solution of the method for disturbance-free switching of temporary chimney CEMS and industrial computer data of a thermal power unit described in the present invention, the equipment module includes a PLC module, a power adapter, a signal distributor, and a Phoenix terminal component.

[0013] As a preferred solution of the method for non-disruptive switching of temporary chimney CEMS and industrial computer data of a thermal power unit described in the present invention, the method of connecting the temporary chimney CEMS device to the distributor and accessing the device module includes: when the remaining memory space of the PLC module is greater than the set threshold, directly inserting the network cable into the port corresponding to the PLC module; if the remaining memory space of the PLC module is less than the set threshold, formulating a wiring plan for accessing the CEMS data to the PLC module according to the PLC memory capacity.

[0014] As a preferred solution of the method for disturbance-free switching of temporary chimney CEMS and industrial computer data of a thermal power unit described in the present invention, the wiring scheme includes: when the CEMS data volume is less than 100 data points and the PLC memory capacity utilization rate is less than 50%, the temporary chimney CEMS device is connected to the PLC module; when the CEMS data volume is greater than 100 data points and the PLC memory capacity utilization rate is between 50%-80%, the CEMS data is divided into multiple signals using a signal distributor and input into different channels of the PLC module; when the CEMS data volume exceeds 80% of the PLC memory capacity and the PLC memory utilization rate is greater than 80%, the CEMS data is stored in an external storage device, and the data in the device is read through the PLC module.

[0015] As a preferred solution of the method for non-disruptive switching of CEMS and industrial computer data of a temporary chimney of a thermal power unit described in the present invention, the environmental parameters include parameters of carbon dioxide, nitric oxide, oxygen, flow rate, pressure, temperature, smoke and humidity.

[0016] As a preferred embodiment of the method for non-disruptive switching of data between the temporary chimney CEMS and the industrial computer of a thermal power unit according to the present invention, the non-disruptive switching includes: when a hardware component of the main industrial computer fails, switching the backup industrial computer to the main industrial computer unit for normal operation, and simultaneously confirming that the software and hardware environment of the backup industrial computer is the same as that of the main industrial computer, and importing configuration files and parameter settings from the backup industrial computer;

[0017] When the operating system of the main industrial computer fails, the on-site staff will restart the main industrial computer to confirm whether the fault is resolved. If the fault is not resolved, the main industrial computer will be switched to the backup industrial computer and the software of the main industrial computer will be inspected and repaired.

[0018] When a communication failure occurs between the main industrial computer and the running equipment, check whether the network connection is normal and determine whether there is a network failure. If there is no network failure, switch the main industrial computer to the backup industrial computer and notify the on-site staff to diagnose and repair the main industrial computer. When the repair is completed, the system checks whether the software environments of the main and backup industrial computers are consistent. If the software environments are inconsistent, the host computer prompts the on-site staff to update the software environment. If the environments are consistent, perform basic function tests, stability tests, and performance tests on the main industrial computer.

[0019] When the database of the main industrial computer fails, all data writing is stopped, and important data is backed up. Preliminary repairs are performed using the database's own recovery function. If the repair fails, the backup industrial computer is switched to the main industrial computer, and the database of the main industrial computer is rebuilt.

During the switching process, if the detection system monitors the real-time status of the backup machine and finds that the takeover fails, the backup machine and the main control machine will be automatically switched back to the original state, and manual intervention will be performed to restore the operating status of the unit through manual operation, and the main control machine will be restarted or the control parameters will be adjusted until the backup machine can take over normally.

[0033] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of the specific embodiments of the present invention is given in conjunction with the accompanying drawings. It is obvious that the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in this field without creative work should fall within the scope of protection of the present invention.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0036] The present invention is described in detail with reference to schematic diagrams. For ease of illustration, cross-sectional views of device structures may be partially enlarged and not to scale when describing embodiments of the present invention. Furthermore, these schematic diagrams are merely illustrative and should not limit the scope of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0037] In the description of the present invention, it should be noted that the terms "upper, lower, inner, and outer" and other references to orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first, second, or third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] In this disclosure, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be interpreted broadly. For example, they may refer to fixed, removable, or integral connections. They may also refer to mechanical, electrical, or direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this disclosure.

[0039] Example 1

[0040] Reference Figure 1 , which is the first embodiment of the present invention, provides a method for non-disruptive switching of data between a temporary chimney CEMS and an industrial computer of a thermal power unit, comprising:

[0041] S1: Connect the temporary chimney CEMS equipment to the distributor and access the equipment module;

[0042] Furthermore, the equipment module includes a PLC module, a power adapter, a signal distributor, and a Phoenix terminal component.

[0043] It should be noted that connecting the temporary chimney CEMS device to the distributor and accessing the device module includes, when the remaining memory space of the PLC module is greater than the set threshold, directly inserting the network cable into the port corresponding to the PLC module; if the remaining memory space of the PLC module is less than the set threshold, then formulating a wiring plan for CEMS data access to the PLC module based on the PLC memory capacity.

[0044] It should also be noted that the wiring scheme includes connecting the temporary chimney CEMS device to the PLC module when the CEMS data volume is less than 100 data points and the PLC memory capacity utilization rate is less than 50%; when the CEMS data volume is greater than 100 data points and the PLC memory capacity utilization rate is between 50%-80%, using a signal distributor to divide the CEMS data into multiple signals and input them into different channels of the PLC module; when the CEMS data volume exceeds 80% of the PLC memory capacity and the PLC memory utilization rate is greater than 80%, using an external storage device to store the CEMS data and reading the data in the device through the PLC module.

[0045] Furthermore, for a smaller number of CEMS data points, the PLC memory capacity is sufficient to store all the data, so the temporary chimney CEMS device can be directly connected to the PLC expansion module for data acquisition. In this case, due to the low memory usage, a signal splitter or other memory management methods are not required.

[0046] Secondly, as CEMS data volume increases, PLC memory capacity may become a limiting factor. If the CEMS data volume is between 50 data points and half the PLC memory capacity, and there is still available memory, it is recommended to use a signal splitter to split the CEMS data into multiple signals and input them to different channels of the PLC module for data acquisition. This helps avoid memory overflow and ensures data integrity and accuracy.

[0047] Finally, when CEMS data volumes are extremely large, the PLC memory may be nearing capacity. In this case, more advanced solutions may be necessary, such as using an external storage device to store the CEMS data and then accessing it through the PLC module. Alternatively, upgrading the PLC module's memory may be considered. These solutions ensure that CEMS data is accurately recorded and processed, and avoid system crashes or failures.

[0048] S2: Use the idle slave IPC of the standby unit to configure the environmental protection parameters of the master IPC of the host unit;

[0049] Furthermore, the environmental parameters include carbon dioxide, nitric oxide, oxygen, flow rate, pressure, temperature, smoke and humidity.

[0050] S3: After the main chimney of the host group is switched to the temporary chimney, the CEMS system is connected to achieve non-disruptive switching.

[0051] Furthermore, the non-disruptive switching includes, when a hardware component of the main industrial computer fails, switching the backup industrial computer to the main industrial computer group for normal operation, and at the same time confirming that the software and hardware environment of the backup industrial computer is the same as that of the main industrial computer, and importing configuration files and parameter settings from the backup industrial computer;

[0052] When the operating system of the main industrial computer fails, the on-site staff will restart the main industrial computer to confirm whether the fault is resolved. If the fault is not resolved, the main industrial computer will be switched to the backup industrial computer and the software of the main industrial computer will be inspected and repaired.

[0053] When a communication failure occurs between the main industrial computer and the running equipment, check whether the network connection is normal and determine whether there is a network failure. If there is no network failure, switch the main industrial computer to the backup industrial computer and notify the on-site staff to diagnose and repair the main industrial computer. When the repair is completed, the system checks whether the software environments of the main and backup industrial computers are consistent. If the software environments are inconsistent, the host computer prompts the on-site staff to update the software environment. If the environments are consistent, perform basic function tests, stability tests, and performance tests on the main industrial computer.

[0054] When the database of the main industrial computer fails, all data writing is stopped, and important data is backed up. Preliminary repairs are performed using the database's own recovery function. If the repair fails, the backup industrial computer is switched to the main industrial computer, and the database of the main industrial computer is rebuilt.

[0055] It should be noted that for basic functional testing: If the main industrial computer needs to communicate with multiple running devices, you can first check whether there are any network connection issues, such as insufficient network bandwidth or incorrect network configuration. If the network connection is normal, you need to test each device individually to ensure that it can correctly respond to the main industrial computer's requests.

[0056] Stability testing: When conducting stability testing, the first step is to rule out the possibility of hardware failure. If no hardware issues are found, various system monitoring and diagnostic tools can be used to analyze device status information and identify potential software or configuration issues. Furthermore, testers should simulate various abnormal conditions, such as power outages or network interruptions, to test device performance in different environments.

[0057] Performance testing: When conducting performance testing, detailed test planning and design are required to ensure that all key points are covered. Testers can first consider the device's hardware and software configuration to identify performance bottlenecks. They can then evaluate the device's performance through stress testing, load testing, and other methods, and provide optimization recommendations based on the test results.

[0058] Furthermore, a problem database is built based on the problems that occur, and the problems that occur are recorded. When the same problem occurs next time, the system calls the database information and performs a system repair. If the system cannot repair it independently, the problem will be displayed on the host computer and an alarm message will be issued to notify the on-site staff or on-duty personnel to assist in the repair.

[0059] Furthermore, the worry-free switching also includes configuring a backup machine with the same software and hardware environment and parameter settings as the main machine, replacing the control function of the main machine with the backup machine through a predetermined strategy, converting the current unit state machine controller state to the unit state at the next moment, optimizing the objective function with the goal of minimizing the switching time, and achieving non-disturbance switching through the optimal controller and signal conversion function. During the switching process, if the detection system monitors the real-time status of the backup machine and finds that the takeover fails, the backup machine and the main machine will be automatically switched back to the original state, and manual intervention will be performed to restore the unit's operating status through manual operation, and the main machine will be restarted or the control parameters will be adjusted until the backup machine can take over normally.

[0060] Example 2

[0061] As an embodiment of the present invention, a method for disturbance-free switching of CEMS and industrial computer data of a temporary chimney of a thermal power unit is provided. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through experiments.

[0062] Taking a two-unit power plant as an example, while Unit 1 was shut down and Unit 2 was operating, the CEMS equipment for the No. 1 desulfurization outlet was first installed on the temporary chimney of Unit 2. All CEMS equipment was pre-commissioned, and then the temporary chimney was switched. The bumpless switchover design was implemented on the operating Unit 2, and online monitoring of the No. 2 outlet was restored in the shortest possible time. After the temporary chimney switchover was completed, the original No. 2 desulfurization outlet CEMS equipment was installed on the temporary chimney of Unit 1. Finally, after the maintenance of Unit 1 was completed, Unit 1 was started up and the temporary chimney switchover was performed, achieving a bumpless switchover.

[0063] The design concept of adding PLC modules and distributors to the CEMS rooms of the two existing units was designed and adopted to ensure the non-disruptive switching of the desulfurization outlet CEMS and industrial computer data of the No. 2 operating unit. The main steps are as follows:

[0064] (1) Purchase PLC expansion modules, power adapters, signal distributors, Phoenix terminal components, etc. separately in advance, cut them into cable troughs and install them, and assemble and wire the above equipment;

[0065] (2) Connect the wiring of the temporary chimney CEMS cabinet to each distributor and the PLC module in advance. After the temporary chimney is switched, just plug the network cable into the port to upload real-time data to the industrial computer and transmit it to the environmental protection website;

[0066] (3) In order to prevent abnormal environmental data, the master-slave redundant industrial computer of Unit 2 could not be configured online. It was reasonably suggested and used that the "slave" industrial computer of the idle unit of Unit 1 (the master industrial computer ensures that the environmental parameters of the idle unit continue to be transmitted normally) be used to configure and set the environmental parameters, including the sulfur dioxide, nitrogen monoxide, oxygen content, flow rate, pressure, temperature, smoke dust, and humidity (SO2 / NO / O2 / V / P / T / W / DUST) parameters of the desulfurization outlet, to ensure that the PLC module parameters are set accurately, which greatly shortens the debugging time after the temporary chimney switch is completed.

[0067] After the main chimney of the No. 2 online unit was switched to the temporary chimney, the CEMS system network cable crystal head was inserted, and the online environmental protection data was connected to the provincial environmental protection department normally, truly achieving "disturbance-free switching".

[0068] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.

For purposes of this specification, a "computer-readable medium" can be any device that can contain, store, communicate, propagate, or transport a program for use by, or in conjunction with, an instruction execution system, apparatus, or device.
