Description

Technical Field

[0001] This invention relates to the field of building automation technology, and more specifically, to a smart Internet of Things control system for controlling various devices in a water-cooled air conditioning system. Background Technology

[0002] In most data centers today, water-cooled air conditioning systems are used for cooling. These systems consist of chillers, water pumps, cold storage tanks, cooling towers (water-cooled chilled water systems), heat exchangers, electric valves, various sensors, and precision air conditioners. The coordinated operation of these devices, except for the precision air conditioners, is achieved by the data center's Building Automation System (BAS). To ensure the security of the BAS, controllers are typically configured with a primary controller and a backup controller. The BAS network architecture usually adopts a ring network architecture, using a continuous ring network to control the various devices in the water-cooled air conditioning system, such as… Figure 1 As shown.

[0003] While existing ring network redundancy solves the problem of single-point failures—meaning that a failure at any point in the network system does not affect the operation of the entire system—it cannot handle multi-point failures. For example, simultaneous failures of the main controller and backup controller can directly paralyze the system. Similarly, multiple failures on communication links can severely impact system operation.

[0004] Furthermore, because all programs are deployed within the controller, the integration level of the programs within the controller is extremely high, with very high coupling between various operational logics, resulting in a lack of flexibility. During the delivery phase after data center construction, the control logic of the BA system needs to be tested, but the testing process cannot simulate all operating conditions of each device. The highly integrated programs are highly likely to cause program deadlocks and other issues during actual data center operation because the testing did not simulate all device operating conditions. When these situations occur, engineers are often unable to perform on-site program modifications and troubleshooting, which becomes a major security vulnerability in data center BA systems. Additionally, when upper-level server program commands, such as energy-saving policies, are issued, the highly coupled logic often hinders the push of control commands, thus affecting the implementation of energy-saving policies.

[0005] Therefore, after dedicated research, the inventor developed a smart IoT control system for controlling various devices in a water-cooled air conditioning system, which overcomes the above-mentioned defects. Summary of the Invention

[0006] To address the above problems, this invention provides a smart IoT control system for controlling various equipment units in a water-cooled air conditioning system. The smart IoT control system includes:

[0007] Multiple smart terminals interact with each other through dual networks. Each smart terminal is electrically connected to a device unit through a communication network. The device unit is divided according to the interlocking relationship of each device in the water-cooled air conditioning system.

[0008] The switch is electrically connected to multiple smart terminals through the communication network;

[0009] The server is electrically connected to the switch via the communication network, and the smart terminal outputs the data collected from the corresponding device unit to the client through the switch and the server.

[0010] Each of the smart terminals is pre-programmed with program logic that enables the corresponding device unit to work and communicate with the other device units in the water-cooled air conditioning system, thereby controlling each device in the water-cooled air conditioning system through the smart terminal.

[0011] In the aforementioned smart IoT control system, the dual networks include a star communication network and an I / O network. The smart terminal is connected to the switch through the star communication network, and each smart terminal is also connected to the other smart terminals through the I / O network. The data collected by each smart terminal is sent to the switch through the star communication network, and is also sent to the other smart terminals through the star communication network and the I / O network.

[0012] In the aforementioned intelligent IoT control system, each of the intelligent terminals includes:

[0013] Sensors are used to collect data from the device unit;

[0014] The I / O module transmits the collected data from the device unit through the I / O network;

[0015] The communication module transmits the collected data from the device unit through the star-shaped communication network;

[0016] The controller has a pre-set program logic that enables the corresponding device unit to work and communicate with the other device units in the water-cooled air conditioning system. After analyzing and judging the working conditions based on the collected data of the device unit, the controller controls the device unit in coordination with at least one other smart terminal according to the program logic.

[0017] The aforementioned intelligent IoT control system, in which,

[0018] The controller determines whether communication with the currently used network has been successfully established;

[0019] If so, the controller outputs the data of the device unit to the other controllers through the network currently in use, and at the same time receives the data of the device unit output by the other controllers;

[0020] If the network is not switched, the controller determines whether communication with the switched network has been successfully established. If so, the controller outputs the data of the device unit to the other controllers through the switched network, and at the same time receives the data of the device unit output by the other controllers.

[0021] In the aforementioned intelligent IoT control system, when the controller determines that communication between the switched network and the controller has failed to be established, the controller controls the corresponding device unit according to the preset program logic.

[0022] In the aforementioned smart IoT control system, after successful communication, when at least one device in the device unit corresponding to a controller fails, the controller outputs a fault signal corresponding to that device to the other controllers. At least one of the other controllers controls its corresponding device unit to operate based on the fault signal through the program logic and sends an enable success signal to the other controllers. The controller that sent the fault signal and its associated controller control its corresponding device unit to shut down according to the enable success signal.

[0023] In the aforementioned smart IoT control system, when communication between the switched network and the controller fails to be established, each controller performs load detection based on the output results of the sensors, and controls its corresponding device unit based on the load detection results through the program logic.

[0024] In the aforementioned smart IoT control system, each controller performs a data integrity check on the data received from the device unit, then sorts the devices of the device unit according to their running time based on the data it outputs and receives from the device unit, and controls the power on / off of each device of the device unit according to the sorting result.

[0025] In the aforementioned smart IoT control system, each controller sorts its corresponding non-operating and fault-free devices in real time according to their cumulative operating time, and controls the non-operating and fault-free devices to start up based on the sorting results according to usage requirements.

[0026] In the aforementioned smart IoT control system, each controller sorts its corresponding running and fault-free devices in real time according to their current running time, and controls the running and fault-free devices to shut down based on the sorting results according to usage requirements.

[0027] The advantages of this invention over existing technologies are as follows:

[0028] 1. The intelligent IoT control system adopts a dual-network architecture of star communication network and mesh I / O network. Each intelligent terminal has intelligent underlying security control logic, which greatly improves the security of data center operation.

[0052] Certain terms used to describe this application will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the application.

[0053] Please refer to Figure 2 - Figure 3 , Figure 2 This is a network topology diagram of the intelligent Internet of Things control system of the present invention; Figure 3 This is a structural diagram of a smart terminal. (Example) Figure 2 - Figure 3 As shown, the present invention discloses a smart IoT control system for controlling various equipment units 4 in a water-cooled air conditioning system. The smart IoT control system includes: multiple smart terminals 11…1N, a switch 2, and a server 3; the multiple smart terminals 11…1N interact through dual networks, and each smart terminal 11…1N is electrically connected to one of the equipment units 41…4N through a communication network. The equipment units 41…4N are divided according to the interlocking relationship of each device in the water-cooled air conditioning system; the switch 2 is electrically connected to the multiple smart terminals 11…1N through the communication network; the server 3 is electrically connected to the switch 2 through the communication network; the smart terminals 11…1N output the data collected from the corresponding equipment units 41…4N to the client 5 through the switch 2 and the server 3; wherein, each smart terminal 11…1N has a pre-set program logic for cooperating and communicating with the other equipment units in the water-cooled air conditioning system, thereby controlling each device in the water-cooled air conditioning system through the smart terminal 11…1N.

[0054] In this embodiment, the dual network includes a star communication network and an I / O network. The smart terminal is connected to the switch through the star communication network. Each smart terminal 11...1N is also connected to the other smart terminals through the I / O network. The data collected by each smart terminal 11...1N is sent to the switch 2 through the star communication network, and is also sent to the other smart terminals through the star communication network and the I / O network.

[0055] Specifically, the smart IoT control system adopts a dual-network architecture. The first is a communication network architecture, where each smart terminal is connected to a switch in a star topology via the communication network. The switch then connects to the server and clients, enabling data exchange between the smart terminals and between the smart terminals and the server and clients. The second is an I / O network architecture, which constructs an I / O network using cables to connect the I / O interfaces of each smart terminal. Information is transmitted between the smart terminals using digital and analog electrical signals input and output through the I / O interfaces. The I / O network serves as a backup network; in the event of a communication network failure, it continues to support communication between the smart terminals, ensuring the normal operation of the smart IoT control system. According to this network architecture, each smart terminal, based on its own intelligent functions, can communicate with each other to receive information from other devices, identify their operating status, and complete collaborative tasks, thus forming an interconnected and intelligent IoT data center (BA) system.

[0056] Based on this, the intelligent IoT control system of this invention breaks away from the traditional ring network architecture of BA systems, adopting a dual-network architecture of a star-shaped communication network and a mesh I / O network. When one network fails, such as the communication network, each intelligent terminal can communicate via electrical signals through the backup network, such as the I / O network, thus ensuring normal system operation. Furthermore, even if all networks in the system are completely interrupted—that is, the communication network, I / O network, switch, and server networks are all interrupted—the independent operation of each intelligent terminal is not affected, and the water-cooled air conditioning system can still maintain normal operation, thus greatly improving the security of the data center control system. At the same time, the deployment of each intelligent terminal follows the principle of equipment redundancy, and there is no interlocking relationship between intelligent terminals. Therefore, the system will only be paralyzed when all similar intelligent terminals in the system fail, causing all similar equipment units in the water-cooled air conditioning system, such as all refrigeration units, to cease operation, thereby improving the redundancy security of the control system.

[0057] Please refer to Figure 3 . Figure 3 This is a structural diagram of a smart terminal. (Example) Figure 3As shown, each of the smart terminals includes: a sensor 111, an I / O module 112, a communication module 113, and a controller 114; the sensor 111 is used to collect data of the device unit; the I / O module 112 sends the collected data of the device unit through the I / O network; the communication module 113 sends the collected data of the device unit through the star communication network; the controller 114 has a pre-set program logic for the corresponding device unit to work and communicate with other device units in the water-cooled air conditioning refrigeration system. After analyzing and judging the working conditions based on the collected data of the device unit, the controller controls the unit device in coordination with at least one other smart terminal according to the program logic.

[0058] Specifically, the smart terminal is the basic unit of the smart IoT control system and also the core part of this smart IoT control system. Its composition is as follows: the entire water-cooled air conditioning refrigeration system is divided into multiple equipment units according to interlocking relationships, such as refrigeration equipment units, cold tower equipment units, piping equipment units, water pump equipment units, and cold storage tank equipment units, etc. Figures 5-10 As shown. Each equipment unit is equipped with a controller, I / O modules and communication modules for equipment control and network communication, as well as sensors reflecting the equipment status, and these control devices constitute a control unit. The controller contains program logic for the coordinated operation and communication between the unit and the entire water-cooled air conditioning refrigeration system. This endows each control unit with intelligent functions such as receiving network information from the refrigeration system, analyzing and judging operating conditions, and realizing coordinated operation with the refrigeration system through logic control. These control units thus form a smart terminal. Smart terminals are categorized according to the specific water-cooled air conditioning system project, and their types include, but are not limited to, smart terminals for refrigeration units, smart terminals for cooling tower units, smart terminals for piping units, smart terminals for water pump units, and smart terminals for cold storage tank units, etc. Figure 4 As shown. The deployment of smart terminals follows the redundancy principle of the refrigeration system. If the chiller in the refrigeration system follows the redundancy principle of 3 in use and 1 in standby, then the smart terminals of the refrigeration units correspond one-to-one with them and also follow the redundancy principle of 3 in use and 1 in standby.

[0059] Based on this, each smart terminal possesses intelligent characteristics, and the system operates autonomously and collaboratively, relying on the intelligent functions and underlying logic of each smart terminal. Therefore, the system program has extremely low integration and high flexibility, preventing program deadlocks and effectively executing upper-level instructions (such as energy-saving strategies). This avoids situations where high program integration hinders instruction execution (such as energy-saving strategy implementation). Thus, the system can effectively collaborate with management platforms that employ AI algorithm models for energy-saving strategies, executing these strategies while ensuring the secure operation of the data center.

[0060] Each smart terminal establishes a communication connection with the others through a smart IoT control system. First, each smart terminal prioritizes the received information according to the operational steps within the cooling system. Then, it executes the program logic sequentially, putting the cooling equipment of each smart terminal into operation. This achieves intelligent, coordinated operation of the entire cooling system. Each smart terminal operates autonomously and collaboratively based on intelligent technology and underlying logic. When other smart terminals malfunction, the normal operation of the terminal remains unaffected. Due to the redundant configuration of the smart terminals in the data center, the normal operation of the cooling system is still guaranteed. Furthermore, when the communication network fails, each smart terminal can communicate via a backup I / O network, and vice versa, thus ensuring the normal operation of the cooling system and greatly improving system security.

[0061] Furthermore, the controller 114 determines whether communication with the currently used network has been successfully established;

[0062] If so, the controller outputs the data of the device unit to the other controllers through the network currently in use, and at the same time receives the data of the device unit output by the other controllers;

[0063] If the network is not switched, the controller determines whether the communication with the switched network is successfully established. If so, the controller outputs the data of the device unit to the other controllers through the switched network, and at the same time receives the data of the device unit output by the other controllers.

[0064] When the controller determines that communication between the switched network and the controller has failed to be established, the controller controls the corresponding device unit according to the preset program logic. When communication between the switched network and the controller has failed to be established, each controller performs load detection based on the output results of the sensor, and controls the corresponding device unit based on the load detection results through the program logic.

[0065] Wherein, after communication is successfully established, when at least one device in the device unit corresponding to a controller fails, the controller outputs a fault signal corresponding to the device to the other controllers. At least one of the other controllers controls its corresponding device unit to work based on the fault signal through the program logic and sends an enable success signal to the other controllers. The controller that sent the fault signal and its associated controller control its corresponding device unit to shut down according to the enable success signal.

[0066] Furthermore, after each controller performs a data integrity check on the data received from the device unit, the controller sorts the devices of the device unit according to their running time based on the data it outputs and receives from the device unit, and controls the power on / off of each device of the device unit according to the sorting result.

[0067] Each controller sorts its corresponding non-operating and fault-free devices in real time according to their cumulative operating time, and controls the non-operating and fault-free devices to start up based on the sorting results according to usage needs. Each controller also sorts its corresponding operating and fault-free devices in real time according to their current operating time, and controls the operating and fault-free devices to shut down based on the sorting results according to usage needs.

[0068] Based on this, the main controller and backup controller configured in traditional BA systems have good performance but are expensive. Although the number of controllers configured in each smart terminal of the smart IoT control system is large, the requirements for controllers and I / O modules are very low. As far as the system is concerned, the overall control equipment cost is less, which can effectively save construction costs.

[0069] Please refer to Figure 11 , Figure 11 This is the control logic diagram for the smart terminal. The following is combined with... Figure 11 The working process of the intelligent Internet of Things control system of the present invention is illustrated by the following example:

[0070] For example, when the network in the system is normal, but the chiller in a refrigeration unit malfunctions:

[0071] ①The smart terminal corresponding to the currently faulty chiller will transmit the chiller fault signal to other smart terminals;

[0072] ② At this time, the smart terminal corresponding to the backup chiller of the backup refrigeration unit receives the fault signal from the faulty unit and starts the refrigeration unit it controls;

[0073] ③The smart terminal corresponding to the interlocked cold tower equipment unit receives the instruction and starts the controlled cold tower equipment unit;

[0074] ④ Once the new refrigeration unit and the cold tower unit are successfully started, their corresponding smart terminals output their status values. The smart terminals corresponding to the faulty refrigeration unit and the interlocked cold tower units receive the signals and execute the shutdown command. The fault trip is successful.

[0075] For example, when all network connections in the system are down, and a chiller fails simultaneously:

[0076] ① All chillers are stopped, and each smart terminal begins load detection due to network disconnection;

[0077] ② At this time, the cooling load drops rapidly because there is no chiller running. The intelligent terminal of the pipeline unit detects the inlet water temperature and enters the cooling state to ensure the operation of the terminal equipment.

[0078] ③ The smart terminal of the standby chiller starts timing due to the reduction in cooling load. If the cooling load still has not returned to normal level after the set time, the chiller unit will be turned on.

[0079] ④ The smart terminal of the standby chiller interlocking chiller tower detects a rapid increase in cooling flow and executes the start-up command;

[0080] ⑤ At this point, since the backup refrigeration unit is operating successfully, the inlet water temperature of the cold storage tank decreases, the cold storage tank enters the charging mode, and the smart terminal of the faulty refrigeration unit detects a rapid increase in cooling load and shuts down the chilled water pump. The system fault trip is successful, and normal operation is restored.

[0081] This invention, a Building Automation (BA) system applied to data center water-cooled air conditioning systems, comprises a smart IoT control system architecture consisting of smart terminals, switches, an upper-level management platform server, and clients. The smart terminals are composed of multiple equipment units, each equipped with a corresponding controller, I / O modules, communication modules, sensors, and other control devices to form a control unit. The program logic is written into the controller, giving it intelligent functions for communication, judgment, and collaborative operation, thus forming a smart terminal. Simultaneously, each smart terminal connects to the system switch and the upper-level management platform server via a star-shaped communication network, enabling data exchange between smart terminals and between the smart terminals and the upper-level management platform. Furthermore, the smart IoT control system adopts a dual-network architecture mode, using both communication and I / O networks. In addition to the communication network, the I / O interfaces of each smart terminal are interconnected via cables to construct an I / O network. Even when all networks in the system are interrupted, each smart terminal can still operate independently, and the water-cooled air conditioning system can continue to function normally.

[0082] In summary, the intelligent IoT control system of this invention adopts a dual-network architecture of star communication network and mesh I / O network. Each intelligent terminal has intelligent underlying security control logic, which greatly improves the security of data center operation. At the same time, it endows the system with intelligence and high flexibility, which can effectively execute upper-level instructions, improve system security, ensure the effective implementation of data center energy-saving strategies, and save costs.

[0083] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
