Description

Technical Field

[0001] The present invention relates to the technical field of water system air conditioning, and in particular to a standardized water system air conditioning remote data acquisition system and method. Background Art

[0002] Water system air conditioners (water system central air conditioners) mainly include host machines, internal circulation pumps (chilled water pumps), external circulation pumps (cooling water pumps), cooling towers, etc. The host machines are used to achieve heat exchange, the internal circulation pumps are used to deliver the internal circulation water to the terminal room to control the temperature of each room, and the external circulation pumps are used to deliver the exchanged heat to the cooling tower for heat dissipation. Energy-saving control of water system air conditioners mainly includes adjusting the power of the host compressor and the power of the water pump, which is achieved by setting the inlet and outlet water temperatures.

[0003] As a necessary equipment for large buildings, hotels, and residences, water system air conditioners have a huge market share. However, due to the blockade of manufacturers, different brands of water system air conditioner hosts have their own protocols and bus forms, and the protocols are not open, so it is difficult to achieve centralized control of water system air conditioner hosts. Water system air conditioners consume a lot of energy. The inlet and outlet water temperatures, water pump speed control, and terminal load conditions all determine the operating efficiency. Centralized control of water system air conditioners plays a decisive role in energy saving in air conditioning systems.

[0004] At present, there are two main solutions for data collection of water system air conditioners: (1) Purchase the original adapter board, realize data communication through the adapter board, and then read the host temperature, pressure, flow and other data, and realize the water system air conditioner host power on and off, temperature setting and other operations through the data protocol. However, the original adapter board is expensive, especially for American air conditioners. Most centralized control solution providers can hardly afford the cost. In addition, due to technical blockade, different manufacturers have their own adapter boards. Each modification project needs to be negotiated and purchased separately, which is a cumbersome process and wastes manpower and material resources. (2) Abandon the original controller and use its own controller and sensor for data collection. However, this method requires external temperature, flow, pressure and other sensors, and requires the original pipeline to be modified. The construction cost is also expensive. Summary of the invention

[0005] The purpose of the present invention is to provide a standardized water system air conditioner remote data acquisition system and method to solve the problem that multi-brand water system air conditioners are difficult to centrally control due to different protocols. In order to achieve the above purpose, the present invention solves the problem through the following technical solutions:

[0006] In a first aspect, the present invention provides a standardized water system air conditioning remote data acquisition system, comprising:

[0007] The screen clicking robot is used to click the water system air conditioning human-computer interaction screen according to the instruction and generate a trigger signal;

[0008] A learning bus repeater, used for receiving the trigger signal and starting to capture the interactive data between the water system air conditioner human-machine interactive screen and the water system air conditioner host;

[0009] The cloud data processing center is used to receive and process the interaction data.

[0010] As a further technical solution, the screen clicking robot is controlled by a back-end control expert and realizes button clicking based on video transmission.

[0011] As a further technical solution, the screen clicking robot has three degrees of freedom, and a screen pressing probe is installed at its execution end.

[0012] As a further technical solution, the pressure screen probe is composed of a spring, a movable push rod and a sliding rheostat.

[0013] As a further technical solution, the learning bus repeater is configured with multiple interfaces to realize bus data collection and forwarding of different brands and interfaces.

[0014] In a second aspect, the present invention provides a working method of the standardized water system air conditioning remote data acquisition system according to the first aspect, comprising the following steps:

[0015] The screen clicking robot clicks the water system air conditioning human-computer interaction screen according to the instructions. After each successful click, a trigger signal is sent to the learning bus repeater. Then the learning bus repeater starts to capture the interaction data between the water system air conditioning human-computer interaction screen and the water system air conditioning host. The interaction data are sent by the learning bus repeater to the cloud data processing center. The interaction data saved by the cloud data processing center are analyzed by manual analysis tools to realize the learning operation of key instructions.

[0016] As a further technical solution, after the learning operation is completed, the screen clicks on the robot and loses control. The control instructions are sent directly from the cloud data processing center to the water system air-conditioning host, and the water system air-conditioning host data is directly collected from the cloud.

[0017] As a further technical solution, the interactive data includes a control code sent by the water system air conditioner human-computer interaction screen and an ACK code returned by the water system air conditioner host.

[0018] As a further technical solution, the screen clicking robot is controlled by back-end control experts, which realizes the clicking of key buttons based on video transmission, imitating the manual operation of the screen process.

[0019] As a further technical solution, the coordinate recording of the function keys is realized based on the coordinate mapping principle, and the operation process is as follows:

[0020] S1: Manual control screen clicks on the end of the robot to reach a button on the water system air conditioning human-computer interaction screen, and enters the corresponding button function and whether to change pages;

[0021] S2: Repeat step S1 to map all buttons for required operations;

[0022] S3: Manually control the screen to click on the robot to map the coordinate position, button function and whether to change pages, and record them in the internal flash;

[0023] S4: The user sorts all buttons at once according to the operations performed;

[0024] S5: The manually controlled screen clicking robot performs the clicking operation according to the button sequence arranged by the user. For the buttons with page switching function, a camera is used to take pictures;

[0025] S6: After the user confirms the setting status before changing pages, the user manually controls the screen and clicks the robot to continue running until all functions are completed.

[0026] The beneficial effects of the present invention are as follows:

[0027] (1) The present invention takes the human-computer interaction screen as the starting point, and realizes the communication protocol learning between the water system air conditioning human-computer interaction screen and the water system air conditioning host through a learning bus repeater, a screen clicking robot, and a cloud data processing center. It simulates the water system air conditioning human-computer interaction screen to send control data to the water system air conditioning host, and then controls the reading of the water system air conditioning host status and key parameters, forming a standardized and replicable water system air conditioning parameter collection and centralized control solution.

[0028] (2) Video transmission is based on the camera, and the screen clicking operation is performed manually, which consumes a huge amount of traffic. The present invention realizes the coordinate recording of the function keys based on the coordinate mapping principle. By running in this way, the traffic cost in the process of remote operation of the screen clicking robot can be greatly saved.

[0029] (3) The present invention fully solves the problem of standardized centralized control in the process of energy saving of water system air conditioners, so that energy-saving companies can quickly realize the connection and communication of the air-conditioning host without having to worry about the specific relevant protocols of the air-conditioning. In addition, the process avoids the need to purchase original factory adapter boards, which greatly saves the project costs of energy-saving companies.

[0030] (4) The present invention makes it possible to adjust the peak power consumption of air conditioners. Water system air conditioners are large energy consumers. If air conditioners are turned on on a large scale in hot weather areas, it may cause overload of the power grid. Based on the control method provided by the present invention, data access and air conditioner control can be achieved through 4G communication, and the operating power of air conditioners can be adjusted in batches to achieve the purpose of peak power consumption of the power grid and avoid the original power outage.

[0037] 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.

[0038] Embodiment 1

[0039] like Figure 1 As shown, this embodiment provides a standardized water system air conditioning remote data acquisition system, including a screen clicking robot 1, a learning bus repeater 3 and a cloud data processing center 5.

[0040] The screen clicking robot 1 is used to click the water system air conditioner human-computer interaction screen 2 according to instructions and generate a trigger signal; in order to realize human-computer interaction, the water system air conditioner host 4 control box is mostly integrated with a touch screen system, and some products realize human-computer interaction through screens and mechanical buttons to realize local control. The human-computer interaction content mainly includes the setting of inlet and outlet water temperature, power on and off control, and reading of the water system air conditioner host status, including inlet and outlet water flow, water temperature, compressor power, etc. These parameters play a major role in energy saving of water system air conditioners.

[0041] The learning bus repeater 3 is used to receive the trigger signal and start capturing the interaction data between the water system air conditioner human-machine interaction screen 2 and the water system air conditioner host 4.

[0042] The cloud data processing center 5 is used to receive and process the interactive data. The cloud data processing center 5 stores a large amount of interactive data between the water system air conditioner human-machine interactive screen 2 and the water system air conditioner host 4. The cloud data processing center 5 is composed of data analysis experts and computer-aided tools, and the analysis of key instructions is realized by combining manual analysis tools.

[0043] The water system air conditioner human-computer interaction screen 2 and the water system air conditioner host 4 are both components of the original water system air conditioner itself.

[0044] This embodiment starts with the human-computer interaction screen, and realizes the communication protocol learning between the water system air-conditioning human-computer interaction screen 2 and the water system air-conditioning host 4 through the learning bus repeater 3, the screen clicking robot 1, and the cloud data processing center 5. It simulates the water system air-conditioning human-computer interaction screen 2 to send control data to the water system air-conditioning host 4, and then controls the reading of the water system air-conditioning host 4 status and key parameters, forming a standardized and replicable water system air-conditioning parameter collection and centralized control solution.

[0045] The screen clicking robot 1 is controlled by a back-end control expert and realizes button clicking based on video transmission.

[0046] Specifically, the screen clicking robot 1 is connected to the installation plate of the water system air conditioning human-computer interaction screen 2. The screen clicking robot 1 is controlled by the back-end control expert, and the clicking of key buttons is realized based on video transmission to imitate the manual operation screen process. The screen clicking robot 1 can run independently to control the state parameters of the water system air conditioning host 4 in real time according to the energy-saving control strategy. At the same time, it can also cooperate with the learning bus repeater 3 to provide a trigger source for the water system air conditioning human-computer interaction screen 2 to send data.

[0047] like Figure 4 As shown, the screen clicking manipulator 1 has three degrees of freedom, and its execution end is equipped with a screen pressing probe 11. The three degrees of freedom are specifically two horizontal rotation degrees of freedom and one vertical movement degree of freedom.

[0048] The screen clicking robot 1 comprises a small arm 12, a large arm 13 and a rising arm 14, which are rotatably connected in sequence. A small arm servo 15 is arranged at the connection between the small arm 12 and the large arm 13, and a large arm servo 16 is arranged at the connection between the large arm 13 and the rising arm 14. A screen pressing probe 11 is arranged at the end of the small arm 12, and the rising arm 14 is slidably connected to a bracket 17, on which a camera 18 is arranged.

[0049] The screen pressure probe 11 is composed of a spring, a movable push rod and a sliding rheostat. When the water system air conditioner human-machine interaction screen is pressed, the spring is compressed, and the movable push rod drives the sliding rheostat to move. The sliding rheostat divides the voltage with the internal voltage divider resistor. The voltage change is collected by the AD acquisition unit of the single-chip microcomputer system, and the magnitude of the downward pressure can be determined by Hu Ke's law. The user can configure the corresponding downward pressure according to the click type.

[0050] like Figure 3 As shown, the learning bus repeater 3 is configured with multiple interfaces to realize bus data collection and forwarding of different brands and interfaces.

[0051] In order to fully adapt to equipment of different ages and brands, the learning bus repeater 3 is equipped with a pair of 485 interfaces, a pair of 232 interfaces, and a pair of Ethernet interfaces. Through multi-interface configuration, it can realize bus data collection and forwarding of different brands and interfaces. The device has an integrated 4G module for cloud access of key data.

[0052] Embodiment 2

[0053] This embodiment provides a working method of the standardized water system air conditioning remote data acquisition system as described in Embodiment 1, comprising the following steps:

Then the learning bus repeater 3 starts to capture the control code sent by the water system air conditioning human-computer interaction screen 2, and waits for the ACK code returned by the water system air conditioning host 4. The interactive data are all sent by the learning bus repeater 3 to the cloud data processing center 5. The interactive data saved by the cloud data processing center 5 are analyzed by manual analysis tools to realize the key instructions, and then the learning operation of the key instructions is realized.

[0055] like Figure 2 As shown, after the learning operation is completed, the screen click robot 1 loses control, and the control command is directly sent from the cloud data processing center 5 to the water system air-conditioning host 4, and the data of the water system air-conditioning host 4 is directly collected by the cloud.

[0056] The screen clicking robot 1 is controlled by a back-end control expert, and realizes the clicking of key buttons based on video transmission, imitating the process of manual screen operation.

[0057] The video transmission is based on the camera, and the screen operation is performed manually, which consumes a huge amount of traffic. This embodiment realizes the coordinate recording of the function keys based on the coordinate mapping principle, and the operation process is as follows:

[0058] S1: Manual control screen clicks on the end of robot 1 to reach a button on water system air conditioning human-machine interaction screen 2, and inputs the corresponding button function and whether to change pages;

[0059] S2: Repeat step S1 to map all buttons for required operations;

[0060] S3: Manually control the screen to click on robot 1 to map the coordinate position, button function and whether to change pages, and record them in the internal flash;

[0061] S4: The user sorts all buttons at once according to the operations performed;

[0062] S5: Manually control the screen clicking robot 1 to perform a clicking operation according to the button sequence arranged by the user, and use the camera 18 to take a photo of the button with a page switching function;

[0063] S6: After the user confirms the setting status before changing pages, the user manually controls the screen and clicks on robot 1 to continue running until all functions are completed.

[0064] By operating in this way, the flow fee in the process of remote operation of the screen clicking robot 1 can be greatly saved.
