Description

Technical Field

[0001] The present invention relates to the technical field of computer room control, and in particular to a computer room group control system based on carrier communication and a rapid implementation method. Background Art

[0002] The computer room group control system is mainly implemented for the cold station computer room, which provides cooling for the entire building system to achieve the cooling effect of the water system central air conditioning. Its main function is to link a series of internal and external related components of the cold station computer room, such as the chiller host, cooling water pump, refrigeration water pump, cooling tower, electric valve, etc., to achieve data collection and overall control capabilities. Its structure is usually a PLC star-connected sensor and actuator. Among them, PLC, as the main control system, is mainly responsible for collecting information from various sensors and controlling the actions of the actuators according to the existing logic. Its topology is shown in the attached figure. Figure 1 shown.

[0003] At present, most of the existing market has not designed a computer room group control system, so this part of the work is generally done manually. For cold station computer rooms that have not installed computer room group control, the implementation of computer room group control mainly includes construction and renovation wiring, point matching debugging, PLC programming, and sensor acquisition signal debugging. Among them, the largest workload is wiring construction, and the biggest impact during the construction process is to ensure the correspondence between the two ends of the wiring harness. In addition, for newly installed sensors and actuators, power supply and communication are usually required. It is usually difficult to obtain power for sensors and actuators locally. Therefore, most scenarios require four-core cables to connect the communication line and the power line to the control cabinet together, which increases the construction cost.

[0004] For cold station computer rooms that have installed computer room group control, the service life of computer room group control equipment is generally 5 to 7 years. After the system exceeds the service life, various abnormal problems will occur. For example, key sensors are damaged and the overall function is lost. Since computer room group control is implemented in a project-based manner, if the designer at the time cannot be contacted, it is difficult to locate the damage after the damage. The traditional solution is to directly dismantle or replace the original computer room group control. However, during the replacement process, the wiring harness and equipment of the original computer room group control cannot be reused, which is equivalent to reinstalling it in the same way as if the computer room group control was not installed. Summary of the invention

[0005] The purpose of the present invention is to provide a computer room group control system based on carrier communication and a rapid implementation method, which can quickly solve the corresponding relationship between sensor and actuator control data and the internal software in the computer room group control. In order to achieve the above purpose, the present invention solves it through the following technical solutions:

[0006] In a first aspect, the present invention provides a computer room group control system based on carrier communication, comprising:

[0007] A conversion board integrates a variety of interfaces compatible with the interface types of sensors and actuators. After accessing the interface, the conversion board can be bound to the configuration information of the sensor or actuator; a carrier communication circuit is also provided;

[0008] The controller integrates a multi-channel carrier circuit, wherein a certain channel of the carrier circuit is connected to a certain carrier communication circuit on the conversion board in an unordered manner using a communication line, and the controller can scan and read the configuration information bound to the conversion board.

[0009] As a further technical solution, the interface types provided on the conversion board include acquisition and output interfaces for digital quantities, current analog quantities, voltage analog quantities, and 485 communication interfaces.

[0010] As a further technical solution, the conversion board integrates a Bluetooth communication circuit, which can be connected to a mobile phone and configure internal parameters through a mobile phone applet.

[0011] As a further technical solution, the controller is also provided with 485, network port and CAN interface.

[0012] In a second aspect, the present invention provides a method for quickly implementing a computer room group control system based on carrier communication, which is implemented using the computer room group control system based on carrier communication as described in the first aspect, and includes the following steps:

[0013] Identify the actuators that need to be controlled and the sensors that need to be collected, identify the interface type, connect to the corresponding interface of the conversion board, and bind the actuator or sensor configuration information to the conversion board; after completing the binding of all actuator and sensor information, connect the carrier communication circuits on all conversion boards to the carrier circuits on the controller in an unordered manner through communication lines; the controller starts the scanning mode and reads the configuration information of all connected conversion boards, thereby realizing the mapping between the controller and the sensor or actuator.

[0014] As a further technical solution, for renovation projects where computer room group control has been installed, the original communication line can be cut at the nearest end of the sensor or actuator, one end connected to the corresponding interface of the conversion board, and the other end connected to the carrier communication circuit, so as to realize the reuse of the original communication line as a power line and a communication line.

[0015] As a further technical solution, for projects where computer room group control is not installed, the laid communication line can be cut at the nearest end of the sensor or actuator, with one end connected to the corresponding interface of the conversion board and the other end connected to the carrier communication circuit.

[0016] As a further technical solution, through a mobile phone applet, the Bluetooth communication circuit of the conversion board is connected, and the type and function of the sensor or actuator connected to the conversion board are input to achieve the binding of the conversion board and the sensor or actuator configuration information.

[0017] As a further technical solution, staff can identify the interface type of the sensor or actuator based on the wiring harness sheath markings.

[0018] The beneficial effects of the present invention are as follows:

[0019] (1) The present invention can quickly resolve the correspondence between the sensor and actuator control data and the controller in the computer room group control by binding configuration information and scanning and reading information. For scenarios without computer room group control, the wiring process of installing and implementing the computer room group control does not need to consider the line sequence, which greatly improves the efficiency of construction wiring and saves labor costs. For scenarios with existing computer room group control, the lines of the original computer room group control can be reused, and there is no need for point matching to confirm the specific point correspondence, saving wiring costs and wire costs.

[0021] (3) The carrier communication circuit provided on the conversion board and the multi-channel carrier circuit provided on the controller in the present invention enable the power supply and communication of the sensor and the actuator to be realized simultaneously by using the communication line, thus saving the wiring cost and the wire material cost.

[0027] The technical solutions in typical embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Example 1

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, this embodiment provides a computer room group control system based on carrier communication, including a conversion board and a controller.

[0029] like Figure 2 As shown, the conversion board integrates a variety of interfaces that are compatible with the sensor and actuator interface types. After accessing the interface, the conversion board can be bound to the sensor or actuator configuration information.

[0030] The interface types set by the conversion board include the acquisition and output interface of digital quantity, current analog quantity, voltage analog quantity and 485 communication interface. The above interface types can adapt to most sensors and actuators on the market. For common control components based on 485 channels such as inverters, the conversion board supports one 485 communication. The interface protocol layer supports multiple protocol types such as MODBUS / RTU and PRFBUS.

[0031] In addition, the conversion board is also provided with a carrier communication circuit, which is connected to the communication line as an output terminal.

[0032] The interface of the conversion board can be connected to sensors and actuators of different interface types, and has good adaptability to meet most needs. It is used as the input end to connect the communication line connected to the actuator or sensor; and the carrier communication circuit can be used as the output end to connect the communication line. For the renovation project of the installed computer room group control, the original communication line is cut at the nearest end of the sensor, one end of which can be connected to the corresponding interface of the conversion board, and the other end of the cut communication line is connected to the carrier communication circuit of the conversion board, so as to realize the reuse of the original communication line as a power line and a communication line.

[0033] The conversion board integrates Bluetooth communication circuits, which can be connected to mobile phones and configure internal parameters through mobile phone applet. The purpose of the setting is to establish communication between the mobile phone and the conversion board through Bluetooth communication, and to use the mobile phone to configure the type and function of sensors or actuators, such as the chilled water outlet temperature of the temperature sensor, and save the configuration information in the conversion board to achieve information binding between the sensor and the conversion board.

[0034] like Figure 3 and Figure 4 As shown, the controller integrates multiple carrier circuits, and a carrier circuit is connected to a carrier communication circuit on a conversion board in an unordered manner using a communication line. The controller can scan and read the configuration information bound to the conversion board.

[0035] In this embodiment, the carrier communication circuit provided on the conversion board and the multi-channel carrier circuit provided on the controller enable the communication lines to be used to simultaneously realize the power supply and communication of the sensor and the actuator, thus saving the wiring cost and the wire material cost.

[0036] The controller of this embodiment is installed in the control cabinet, using Linux to enhance the data and logic processing capabilities. Each carrier circuit can be connected to one or more conversion boards, but in this embodiment, they are connected one by one. In addition, the controller also has universal interfaces such as 485, CAN, and network ports for communication purposes. Example 2

[0037] This embodiment provides a rapid implementation method of the computer room group control system based on carrier communication as described in Embodiment 1, including the following steps:

[0038] Clearly identify the actuators that need to be controlled and the sensors that need to be collected, and identify the interface type. The staff can identify the interface type of the sensor or actuator based on the wiring harness outer sheath markings.

[0039] After determining the interface type, cut the communication line at the nearest end of the sensor or actuator and connect it to the corresponding interface of the conversion board (such as current output, voltage input, 485, etc.). Specifically, for renovation projects that have installed computer room group control, the original communication line can be cut at the nearest end of the sensor or actuator, one end connected to the corresponding interface of the conversion board, and the other end connected to the carrier communication circuit, so as to realize the reuse of the original communication line as a power line and a communication line. For projects without computer room group control installed, the laid communication line can be cut at the nearest end of the sensor or actuator, one end connected to the corresponding interface of the conversion board, and the other end connected to the carrier communication circuit.

[0040] Bind the actuator or sensor configuration information to the conversion board; specifically, connect the Bluetooth communication circuit of the conversion board through the mobile phone applet, input the type and function of the sensor or actuator connected to the conversion board, and realize the binding of the conversion board and the sensor or actuator configuration information.

[0041] After all sensors and actuators have completed the binding of all actuator and sensor information according to the above method, inside the control cabinet, the carrier communication circuits on all conversion boards are connected to the carrier circuits on the controller through communication lines in an unordered manner. In this process, there is no need to pay attention to the wiring sequence, and fast wiring can be achieved.

[0042] After completing the above operations, the controller starts the scanning mode and reads the configuration information of all connected conversion boards, thereby realizing the mapping between the controller and the sensor or actuator, and establishing the corresponding relationship.

[0043] The technical solution of this embodiment can quickly solve the correspondence between the sensor and actuator control data and the controller in the computer room group control by binding configuration information and scanning and reading information. For scenarios without computer room group control, the wiring process of installing and implementing computer room group control does not need to consider the line sequence, which greatly improves the efficiency of construction wiring and saves labor costs. For scenarios with existing computer room group control, the lines of the original computer room group control can be reused, and there is no need for point matching to confirm the specific point correspondence, saving wiring costs and wire costs.

[0044] Although the present invention has been disclosed as above in the form of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art may make possible changes and modifications to the technical solution of the present invention by using the methods and technical contents disclosed above without departing from the spirit and scope of the present invention. Therefore, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall fall within the protection scope of the technical solution of the present invention.
