Description

Technical Field

[0001] The present application relates to the field of smart water technology, and specifically to a method for automatically setting communication parameters of pump room equipment based on VSOA. Background Art

[0002] In the smart water scenario, the main goal is to monitor various data on the water site. Therefore, data collection and control of sensors or controlled devices is the most basic and important part. In actual pump rooms, various sensor devices (such as current sensors, pressure sensors, flow sensors) are used, and there are also many different types of control devices (such as water pumps, frequency converters, solenoid valves, etc.). To realize the informatization and intelligence of the pump room, the central control module needs to communicate with these different sensors, and then further data collection and control can be carried out.

[0003] Currently, in the water pump room, the communication protocols used by the central control module to deal with the bottom-level sensor equipment are basically traditional industrial buses, such as ModbusRTU, RS485, etc. Before establishing this communication, the most basic thing is to configure various communication parameters, including the definition of the device station number, station number setting, baud rate setting, etc. Because all sensor devices are eventually connected to the same bus after entering the central control module, the setting of communication parameters must be unified and needs to be determined by the internal program design framework of the central control module to ensure no conflict.

[0004] The parameter confirmation and setting of sensors or controlled devices is the most tedious process in the on-site construction and debugging of the entire smart water industry. After the pump room of smart water enters the debugging stage, all equipment on site has been installed, and the construction and wiring of the central control module have also been completed. However, the sensors or controlled devices of various manufacturers that have been installed are still configured according to their parameters before leaving the factory. If there is only a single device on site, the central control module can also be set according to the communication parameters of the device without any conflict. But in fact, there are many devices on site and the parameters are messy. If the communication parameters of all sensors or controlled devices are not uniformly processed, the central control module cannot recognize them, let alone data collection and equipment control. In addition, the construction personnel who install and wire the equipment are different technical groups from the final debugging personnel, which also adds a lot of difficulty to the final debugging work. At present, in the final information debugging stage of the smart water industry, the debugging personnel implement the unified configuration of communication parameters according to the following method and process:

[0005] 1. Find and confirm the types, quantities, installation locations and wiring methods of all sensors and controlled equipment in the pump room;

[0006] 2. Confirm the interface type and wiring method of each sensor and controlled device to the central control module (including confirming one by one according to the line number corresponding to the sensor);

[0007] 3. Classify the equipment according to the confirmed information, and plan and define the communication parameters of sensors and controlled equipment according to the actual layout of the on-site equipment or the configuration structure defined within the system;

[0008] 4. According to the defined communication parameters (such as device station number, baud rate, etc.), manually set the sensors and controlled devices connected to the system one by one;

[0009] 5. On the central control module side, conduct overall communication testing and data docking for all sensors and controlled devices.

[0010] It can be seen that with the existing technology, the process of setting the communication parameters of sensors and controlled devices is very cumbersome, and the entire process requires manual access. Once too many human factors intervene, the probability of error is very high. As the number of sensor equipment and controlled equipment in the pump room increases, the more cumbersome it is, the greater the probability of error, and the longer the project delivery cycle.

[0027] S5: After the search for the first access device and the setting of the communication parameters are completed, the device detection module starts to automatically search for the second access device of the access system, and the data buffer channel opens a second communication channel for communicating with the second access device, while shielding the communication channel between the central control module and other access devices;

[0039] The technical solutions in the embodiments of the present application are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0040] In this article, the term "comprising" is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, the elements defined by the sentence "comprising..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0041] In the scenario of informatization debugging of smart water services, when using existing technical methods, engineers need to disassemble the communication wiring of each sensor or controlled device again, and then confirm each sensor or controlled device one by one, and set and test the communication parameters. After completing the parameter setting of the sensor or controlled device, it is necessary to reconnect its communication line to the central control module, and finally perform overall joint debugging of all devices from the central control module side. The entire process requires manual operation confirmation, and there are various uncontrollable and uncertain factors.

[0042] In this regard, this embodiment provides a Figure 1The method for automatically setting the communication parameters of pump room equipment based on VSOA shown in the figure comprises the following steps:

[0043] Step 1: Build an automatic control system;

[0044] Step 2: Start the automatic control system, which identifies the access device and automatically allocates or sets relevant parameters to achieve automatic connection with the access device, automatic data acquisition and automatic control of the device.

[0045] Wherein, the access device includes a sensor and a controlled device; Figure 2 As shown, the automatic control system includes a central control module and a VSOA service framework; the central control module is configured to: connect to various sensors and controlled devices in the pump room downward, and connect to various service platforms upward, and is the main control center of the entire system; the VSOA service framework is embedded in the central control module, and is a microservice communication architecture based on mission-critical areas, and is configured to: adopt a URL subscription and publishing model, and use a unified URL resource tag to achieve reliable and fast data publishing and processing.

[0046] Specifically, the central control module includes a data buffer channel, a detection model warehouse, a device detection module, a device information storage module, and a communication parameter setting module. The central control module uses the VSOA service framework to quickly realize the selective opening and blocking of the "data buffer channel" and other data access during the identification process of the sensor or the controlled device, which is a key technology for realizing automatic identification of sensor devices.

[0047] The data buffer channel is configured to separate and aggregate different sensors or controlled devices on a communication bus;

[0048] The detection model warehouse is configured to store parameter information of various sensors and controlled devices, and construct models of various sensors and controlled devices; the central control module abstracts different models (such as abstracting water pump models, flow sensor models, temperature sensor models, etc.) by classifying, sorting and refining this information. The classified and refined parameter information includes the name, data type, data structure, data format, device control method, device communication parameters, etc. of the collected data. Relying on these abstractions to form models, when the central control module uses the VSOA service framework for device identification, it only needs to call the corresponding model (without caring about or calling the specific subdivided parameter content) to automatically realize the matching detection of the specific communication parameter block under the model.

[0049] The device detection module is configured to: identify the access device based on the parameter information in the detection model warehouse; it is a detection mechanism of the central control module, which identifies different sensors and controlled devices in the access system by polling various device models stored in the warehouse.

[0050] The device information storage module is configured to store definition information of various sensors and controlled devices in the pump room; the definition information includes communication information; these definition information are related to the program framework of the central control module, and the central control module's setting principles for the parameters of the measured sensors and controlled devices, as well as the subsequent reading and writing operations of the data by the entire system, are all called and processed based on the data information in this module.

[0051] The communication parameter setting module is configured to set the communication parameters of the sensor under test or the controlled device based on the definition information stored in the device information storage module.

[0052] Based on the design of the central control module above, it should be noted that before performing step 2, all access devices have been installed and the construction and wiring with the central control module have been completed. Furthermore, step 2 specifically includes:

[0053] S1: Using the model polling detection method, the device detection module uses the VSOA service framework to access the model 1 of the detection model warehouse, wherein the access method is directly executed through the URL address method; the device type corresponding to the model 1 is , It is a sensor device or a water pump device (it can also be a more detailed division such as the aforementioned water pump device, flow sensor device, temperature sensor device, etc.); after accessing model one, the device detection module extracts the parameter information corresponding to model one, and the communication parameter setting module sets the communication parameters inside the central control module according to the same parameter value and format as the parameter information;

[0054] S2: The central control module uses the VSOA service framework to command the data buffer channel to open a first communication channel for communicating with the first access device by writing a URL address, and shields the communication channel between the central control module and other access devices. When the parameter information of the first access device meets the parameter information of the model 1, the first access device automatically establishes a communication connection with the central control module;

[0055] S3: After the communication connection is established, the communication parameter setting module starts to work and retrieves the device information storage module. Definition information of the device; when When representing a sensor device, set the station number of the first connected device to ,when When representing a water pump device, set the station number of the first connected device to ,in, is the total number of sensors in the access device;

[0056] S3: When the parameter information of the first access device does not conform to the parameter information of the model 1, the device detection module selects the model 2 from the detection model warehouse, and repeats steps S1-S4 for identification until a model conforming to the first access device is found;

[0057] S5: After the search for the first access device and the setting of the communication parameters are completed, the device detection module starts to automatically search for the second access device of the access system, and the data buffer channel opens a second communication channel for communicating with the second access device, while shielding the communication channel between the central control module and other access devices;

[0058] S6: The central control module performs the following steps S1 to S5: Access devices to retrieve and set communication parameters;

[0059] S7: After all access devices have completed the communication parameter settings, the central control module notifies the data buffer channel to open all communication channels in VSOA mode. At this time, all access devices are hung on one bus, and the central control module is connected to all access devices to complete subsequent data collection and control.

[0060] In order to more clearly describe the technical solution recorded in this embodiment, this embodiment takes a pump room with 1 "temperature sensor", 2 "flow sensors", and 3 "water pumps" as an example, and explains how the technology of this embodiment is implemented through comparative analysis. Among them, the basic premise is that the various sensors in the pump room come from different manufacturers and different brands. Before the information function debugging, all sensors and controlled equipment have been installed, and the construction wiring with the central control module has also been completed.

[0061] First, under the above conditions, the operation mode of the prior art is:

[0062] 1. Engineers confirm the actual installation location, wiring method and specific line number of equipment such as "temperature sensor", "flow sensor" and "water pump" on site;

[0063] 2. According to the planning of the sensor structure when the control system is designed, the communication parameters of the above sensors and controlled devices are uniformly classified, including the allocation and definition of communication sites;

[0064] 3. On the central control module side, or on the device side, remove the communication wiring between the device and the central control module, connect the device communication line to the debugging computer separately, and use the device-specific host computer tool to set the communication parameters of the sensor or controlled device one by one (such as resetting the station number). The parameter setting rules follow point 2;

[0065] 4. After the communication parameters are set, reconnect the communication line of the device to the central control module, and perform a communication test on the device on the central control module side to ensure that the control system can connect to the device;

[0066] 5. Other sensors and controlled devices are removed, modified, wired and tested one by one in the same way;

[0067] 6. After all the sensors and controlled equipment have established communication, the central control module can start the next step of data collection and equipment control operations.

[0068] It can be seen that the existing method of setting communication parameters such as station number requires the sensors or controlled devices to be disconnected, modified, wired and tested one by one, which is inefficient and cannot guarantee reliability.

[0069] Under the above conditions, the method for automatically setting the communication parameters of the pump room equipment based on VSOA in this embodiment, after starting the central control module, the automatic control system starts to automatically identify and process all the access devices in the local area network one by one, specifically:

[0070] 1. Use the model polling detection method. First, the "device detection module" uses the VSOA service framework to access the "model 1" (such as the "water pump model") of the "detection model warehouse". The access method is directly executed through the URL address method (such as: "VSOA: / / detection model warehouse / model 1..."). After accessing model 1, the detection system directly extracts the parameter values ​​of model 1 (such as baud rate 9600bit / s, station number 1), and sets the communication parameters inside the central control module according to the same parameter value and format (baud rate is set to 9600bit / s, station number of the access device is 1, etc.).

[0071] 2. The central control module also uses the VSOA service framework. By writing the URL address, it commands the "data buffer channel" to open the first communication channel (because it is the first sensor) and shield the communication channel between the system and other devices (that is, retain the Figure 1Channel 1 is disabled, and channels 2 to 6 are shielded), so in effect, it is equivalent to having only one sensor or controlled device hanging on the bus. At this time, the central control communication parameters are set to be consistent with the "water pump model". If the parameter information of the sensor or controlled device meets the "water pump model" (i.e., water pump), then the device will automatically establish a communication connection with the central control module.

[0072] 3. After meeting the "water pump model" and establishing a connection, the "communication parameter setting module" starts working and retrieves the number of water pump devices, the station number information defined by the system, the baud rate, etc. from the device information storage module (for example, there are 3 water pumps, the station numbers are 4, 5, and 6 respectively, and the baud rate is 9600 bit / s. Among them, this information is not the factory information of the sensor or the controlled equipment, but the communication parameter information defined by the central control module for the entire smart water pump project under the information program framework). Set the first water pump detected to 4 and the baud rate to 9600 bit / s (this is no longer the default factory parameter setting of the water pump equipment, nor is it the communication parameter recognized by the "water pump model"). If the water pump is already the third water pump device on the bus, set the water pump station number to 6, and so on.

[0073] 4. If the first sensor or controlled device does not conform to the "water pump model", it means that the sensor or controlled device is not a water pump. The "device detection module" will select another model 2 (such as the "flow sensor" model) from the "detection model warehouse" and continue to identify according to steps 1 to 4 until a model that conforms to the sensor or controlled device is found.

[0074] 5. After the retrieval and communication parameter setting of the first sensor are completed, it means that the central control module can communicate with it according to the original program design framework. The "device detection module" starts to automatically retrieve the second sensor device connected to the system. The central control module still uses the VSOA service framework to write commands through the URL address to notify the "data buffer channel" to open the second communication channel, while blocking the communication channel with other devices (that is, retaining Figure 1 Channel 2 is blocked, and channels 1, 3~6 are shielded).

[0075] 6. The central control module searches and sets the second, third, fourth, etc. sensor or controlled device in the same manner as in steps 2 to 5 above.

[0076] 7. After all sensors or controlled devices have completed the communication parameter settings, the central control module uses the VSOA method to notify the "data buffer channel" to open the communication channels of all devices. At this time, all sensor devices or controlled devices are hung on a bus. The central control module can connect with all devices according to the original program design architecture and design intent to complete subsequent data collection and control.

[0077] It can be seen that with this technology, after the installation and wiring construction of all sensors or controlled devices on site are completed, the commissioning engineers do not need to re-disconnect the wires, confirm the equipment one by one, and set the parameters. Just press the start button, and the central control module can automatically complete the detection of the connected equipment and self-set the communication parameters. The whole process does not require manual intervention, which improves reliability and efficiency, and shortens the delivery cycle of smart water information projects.

[0078] In summary, the characteristics of the method for automatically setting the communication parameters of pump room equipment based on VSOA in this embodiment are as follows:

[0079] 1. The central control module abstracts different sensors or controlled devices into different model organizations according to their characteristics, parameter properties, and device attributes, and stores them in the "device model warehouse". This model organization serves as the basis for the "device detection module" to identify sensors or controlled devices connected to the system.

[0080] 2. After different sensors or controlled devices enter the central control module, they enter different "data buffer channels" according to their classification, and then converge on the bus interface. This signal access method and structure provides the hardware conditions for subsequent automated detection.

[0081] 3. The "device detection module" uses the VSOA service framework to poll various "models" in the "detection model warehouse", and calls the model directly using the URL address access method (such as: "VSOA: / / detection model warehouse / model 1...").

[0082] 4. The central control module selectively opens and blocks the "data buffer channel" based on the detection object by using the URL address writing method of the VSOA service framework structure.

[0083] 5. Before identifying the sensor or controlled device, first fix the sensor or controlled device to be tested in order, and match the device to be tested by polling different models in the "Device Model Warehouse" to identify the type of device to be tested.

[0084] 6. In the process of polling different models in the "device model warehouse", the central control module will dynamically modify the communication parameters in its own system according to the selected model organizations to find out whether it matches the object to be tested. Until the selected model organization matches the properties of the sensor or controlled device, it is judged that the object to be tested belongs to the model organization selected at this time.
