Description

Technical Field

[0001] The present invention relates to the technical field of greenhouse environment control air conditioning, and in particular to a mobile terminal centralized control method and system for greenhouse environment control air conditioning. Background Art

[0002] Air conditioners are HVAC equipment that controls the ambient temperature. In order to control the temperature, current air conditioners are generally equipped with corresponding control panels for each independent device or each duct unit of the central air conditioner to control the temperature and working mode of each part of the space. In some environments where large areas need to centrally control the working status of equipment and achieve precise temperature control, it is necessary to manually switch each unit one by one, or use computer batch control. For unattended operation, time-sharing control is required, and even control is required according to changes in the natural environment such as environment, season, and sunshine. Computers or PLCs rely on complex wiring and programming to achieve precise temperature control, and the flexibility is relatively poor. At present, there is no means that have flexible temperature adjustment, simple deployment, no programming, batch control, and timed automatic control.

[0003] In the use of conventional temperature control equipment, there are generally only two ways to adjust the temperature: cooling or heating. However, when the ambient temperature exceeds the preset value, the device will enter standby mode. For example, if the heating temperature of the air conditioner is set to 26 degrees Celsius, and the actual ambient temperature is 30 degrees Celsius, the device will generally stop working and cannot control the temperature at the set temperature. It will only enter standby mode, or the device's own PID algorithm will control the switching of working modes. For environments that require precise temperature control, such as workshops, agricultural production, and livestock farms, control panels or remote controls usually do not have this function. The use of controllers such as PLCs and single-chip microcomputers requires complex programming logic, and the programs are relatively rigid, difficult to use, and unable to adapt to the impact of environmental changes. Therefore, temperature control failure may cause relatively large losses. Summary of the invention

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0018] It should be noted that, in the description of the present invention, terms such as "up", "down", "left", "right", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is merely for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0019] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Embodiment 1:

[0020] like Figure 1 As shown, a mobile terminal centralized control method for greenhouse environment control air conditioner is applied to the mobile terminal centralized control system of greenhouse environment control air conditioner described in Example 2, see Figure 2 The system includes a mobile terminal with communication connection, multiple greenhouse environment control air conditioners and a server. The greenhouse environment control air conditioners can be household air conditioners, commercial air conditioners, central air conditioners, fresh air fans, humidifiers, dehumidifiers, etc.

[0021] The control method comprises the following steps: Step S10: setting the current working mode and / or working parameters through the mobile terminal and transmitting them to the server; It should be noted that: the server may be but is not limited to an IoT cloud server, and the IoT cloud server is connected to the mobile terminal through wireless communication, such as using a cellular network for communication connection; a human-computer interaction interface is set on the mobile terminal, and convenient and quick settings can be made through the human-computer interaction interface. The mobile terminal may be but is not limited to a smart phone; the working parameters may include constant temperature, temperature value, cooling mode target temperature, heating mode target temperature, scheduled start time, scheduled shutdown time and / or greenhouse environment control air conditioning grouping, etc.

[0022] Step S20: the server determines whether the current working mode is a constant temperature mode; It should be noted that the server matches the received current working mode with the preset mode, which may include constant temperature mode, custom mode, etc. When the signal corresponding to the current working mode is consistent with the signal corresponding to the constant temperature mode, the server determines that the current working mode is the constant temperature mode. The constant temperature mode means: maintaining a constant temperature in a certain area or the entire area. The temperature value in the constant temperature mode can be set in real time or as a preset value to meet different real-time temperature requirements.

[0023] Step S30: If the current working mode is the constant temperature mode, the server obtains the real-time temperature transmitted by each greenhouse environment control air conditioner; It should be noted that each greenhouse environment control air conditioner is provided with a temperature sensor, which can detect the ambient temperature of the area where the greenhouse environment control air conditioner is located in real time and transmit it to the server.

[0024] Step S40: The server calculates an average temperature based on all real-time temperatures. The average temperature is the average temperature of a certain area or the entire area in the constant temperature mode. Step S50, comparing the average temperature with the constant temperature; Step S60: Generate a control signal for each greenhouse environment control air conditioner according to the comparison result, and then transmit the control signal to the corresponding greenhouse environment control air conditioner; in this embodiment, the comparison between the average temperature and the constant temperature can be as follows: If the average temperature is within the range of ±1°C of the constant temperature, the control signals are all maintenance signals, indicating that no adjustment is required and the operation can be maintained; If the average temperature is not within the range of ±1°C of the constant temperature, the real-time temperature transmitted by each greenhouse environment control air conditioner is compared with the constant temperature. According to the comparison result, the control signal generated is a cooling signal, a heating signal or a maintenance signal; Transmit cooling signal, heating signal or maintenance signal to the corresponding greenhouse environment control air conditioner.

[0025] It should be noted that: when the average temperature is not within the range of the constant temperature ±1°C, it indicates that the temperature value of the area where one or more greenhouse environment control air conditioners are located has exceeded the required range and needs to be adjusted. The specific adjustment is determined based on the real-time temperature transmitted by each greenhouse environment control air conditioner. For example: the real-time temperature transmitted by one of the greenhouse environment control air conditioners is greater than the constant temperature +1°C, indicating that the real-time temperature of the area where this greenhouse environment control air conditioner is located has exceeded the maximum value and needs to be cooled. The control signal transmitted by the server is used to cool it, thereby adjusting the real-time temperature of the area; similarly: when the real-time temperature transmitted by one of the greenhouse environment control air conditioners is less than the constant temperature -1°C, it indicates that the real-time temperature of the area where this greenhouse environment control air conditioner is located is lower than the minimum value and needs to be heated. The control signal transmitted by the server is used to heat it, thereby adjusting the real-time temperature of the area; when the real-time temperature transmitted by one of the greenhouse environment control air conditioners is within the range of the constant temperature ±1°C, it indicates that the real-time temperature of the area where this greenhouse environment control air conditioner is located meets the demand and does not need to be adjusted. The control signal transmitted by the server keeps it running. Of course, the present invention can set the temperature upper limit value and the temperature lower limit value. When the real-time temperature transmitted by one of the greenhouse environment control air conditioners is greater than the temperature upper limit value, or less than the temperature lower limit value, the control signal transmitted by the server can be shutdown, thereby ensuring the safety of operation.

[0026] Step S70, each greenhouse environment control air conditioner switches to a corresponding working mode according to the received control signal, and then executes step S20 to form a PID closed-loop control in sequence. In this embodiment, the following steps are specifically included: The greenhouse environment control air conditioner maintains the current working mode according to the received maintenance signal, and then executes step S20; The greenhouse environment control air conditioner switches to the cooling mode according to the received cooling signal, and then executes step S20; The greenhouse environment controls the air conditioner to switch to the heating mode according to the received temperature increase signal, and then executes step S20.

[0027] It can be seen that the mobile terminal centralized control method of the greenhouse environment control air conditioner of the present invention can set the current working mode of the entire area through the mobile terminal, and control the working mode and operating parameters of each greenhouse environment control air conditioner through the server, so that a certain area or the entire area maintains a constant temperature, and the entire constant temperature adjustment does not require manual adjustment. In a production environment where different temperatures need to be set at different time periods, such as agricultural planting, it is necessary to control the ambient temperature at certain times to avoid losses caused by temperature changes and increase production. PLC or panel still cannot achieve the function of flexible control.

[0028] In actual use, the system can automatically determine the working mode that all devices in the environment should switch to, and perform heating or cooling, based on the real-time temperature collected and the constant temperature set by the user through the mobile terminal. The change in ambient temperature is a continuous and gradual process. When waiting for the next sampling, the working mode of the next node is re-determined. This process repeats and repeats to achieve a constant temperature in a local environment.

[0029] The mobile terminal centralized control method of the greenhouse environment control air conditioner of the present invention further includes the following steps: Step S20: The server determines whether the current working mode is a custom mode; It should be noted that the custom mode in the present invention mainly includes a time segment mode and an on-site configuration mode.

[0030] Step S30: If the current working mode is the custom mode, execute step S61; Step S61, the server obtains the control signal and operating parameters of each greenhouse environment control air conditioner through the working parameters or the preset operating parameters, and then transmits the control signal and operating parameters to the corresponding greenhouse environment control air conditioner, and then executes step S71; Step S71: Each greenhouse environment control air conditioner switches to a corresponding working state according to the received control signal and operating parameters.

[0031] In order to understand the custom mode more clearly, the following describes it in different situations: After determining that the current working mode is the custom mode, the server determines whether the custom mode is a time-divided mode; If the custom mode is time period mode, the server obtains the current time period; Then, the preset operating parameters are obtained according to the current period; By presetting the operating parameters, the control signal and operating parameters of each greenhouse environment control air conditioner are obtained, and the control signal and operating parameters are transmitted to the corresponding greenhouse environment control air conditioner; Each greenhouse environment control air conditioner switches to a corresponding working state according to the received control signal and operating parameters.

[0032] It should be noted that the control signals are heating, cooling, maintaining, powering on and powering off, and the operating parameters include but are not limited to temperature values, operating time, etc. The temperature value specifically refers to the temperature value of the greenhouse environment to control the operation of the air conditioner. In actual use, the user can divide a day into several time periods in advance through the mobile terminal, and can set the temperature value, working mode, etc. in each time period separately. When the current working mode is the time period mode, the server calls the preset operating parameters according to the current time period to control the corresponding greenhouse environment to control the operation of the air conditioner, and the required temperature environment can be obtained without manual monitoring. Of course, the operating parameters of each time period can be modified in real time.

[0033] If the current working mode is the custom mode, the server determines whether the custom mode is the field configuration mode; in addition, the field configuration mode is the control panel that comes with the air conditioner, and the working parameters can be overwritten by the instructions sent by the server, and the parameters configured on site can also overwrite the instructions sent by the server; If the custom mode is the on-site configuration mode, the server will work according to the parameters; Obtaining control signals and operating parameters of each greenhouse environment control air conditioner, and then transmitting the control signals and operating parameters to the corresponding greenhouse environment control air conditioner; Each greenhouse environment control air conditioner switches to a corresponding working state according to the received control signal and operating parameters.

[0034] It should be noted that the working parameters are the temperature value, working mode (cooling mode, heating mode, shutdown and startup) and running time set by the user through the human-computer interaction interface of the mobile terminal. When the actual time is set, the user can quickly adjust it according to actual needs to meet different needs, and the operation is convenient.

[0035] In this embodiment, step S20 also includes: The server determines whether the current working mode is one-key startup; The server determines whether the current working mode is one-key shutdown; Step S30 also includes: if the current working mode is one-key startup, the server transmits a one-key startup signal to each greenhouse environment control air conditioner, and executes step S10; If the current working mode is one-key shutdown, the server transmits a one-key shutdown signal to each greenhouse environment control air conditioner, and executes step S10. The greenhouse environment control air conditioners with one-key shutdown and one-key startup can be each greenhouse environment control air conditioner in the same greenhouse.

[0036] Through the above steps, users can use the mobile terminal and server to realize one-key power on and one-key shutdown functions, making it more convenient to use and easier to operate.

[0037] In summary, the present invention makes full use of the Internet of Things, cloud computing and sensor technology to connect the greenhouse environment control air conditioner to the Internet, solving the problem that conventional equipment cannot maintain a constant temperature; it can realize unattended control according to the instructions issued by the user from the mobile terminal, through server data collection and processing, and the temperature fluctuation range can be achieved by ±1°C. The custom time period control function greatly reduces the difficulty of integrated wiring through the Internet of Things technology, avoiding the problems of difficulty in getting started with PLC, relatively rigid programs, high costs, and inflexible configuration. Allow users to adjust the control environment temperature in a timely manner according to actual production needs, which is more efficient; it achieves the significant advantages of good temperature control effect, manpower saving, and low deployment cost. Embodiment 2:

[0038] like Figure 2 As shown, a mobile terminal centralized control system for a greenhouse environment control air conditioner can apply the mobile terminal centralized control method for a greenhouse environment control air conditioner described in Example 1. The system of the present invention includes a server 2, a mobile terminal 1 that is communicatively connected to the server 2, and multiple greenhouse environment control air conditioners 4.

[0039] Each greenhouse environment control air conditioner 4 is respectively communicated with the server 2 and the mobile terminal 1. A temperature detection unit 5 and a data transmission unit 3 are set on each greenhouse environment control air conditioner 4. The temperature detection unit 5 is used to detect the real-time temperature and transmit it to the server 2 through the data transmission unit 3. The data detection unit is bidirectionally communicated with the server 2; the mobile terminal 1 is used to set the current working mode and working parameters, and transmit them to the server 2, which is used to control each greenhouse environment control air conditioner 4 and to control the power on and off of all greenhouse environment control air conditioners 4 with one click; the server 2 is used to control each greenhouse environment control air conditioner 4 according to the received current working mode, working parameters and real-time temperature.

[0040] The mobile terminal 1 is connected to the server 2 by wireless communication, and the server 2 is connected to each greenhouse environment control air conditioner 4 by wired communication or wireless communication. The mobile terminal is connected to the Internet through wireless communication and communicates with the server; each greenhouse environment control air conditioner is connected to the Internet through wired communication or wireless communication and communicates with the server.

[0041] A human-machine interaction interface is provided on the mobile terminal 1, and the working mode and operating parameters of each greenhouse environment control air conditioner 4 are set through the human-machine interaction interface.

[0042] The server 2 controls each greenhouse environment control air conditioner 4 to start up and shut down at a scheduled time; or, each greenhouse environment control air conditioner 4 starts up and shuts down at a scheduled time by itself.

[0043] When the mobile terminal centralized control system of the greenhouse environment control air conditioner 4 of the present invention is actually used, multiple greenhouse environment control air conditioners 4 are configured in a certain area, and each greenhouse environment control air conditioner 4 establishes a communication connection with the mobile terminal 1 and the server 2 respectively. Specifically, a wired connection can be established using a network cable or optical fiber, and a wireless connection can be established using a cellular network.

[0044] All greenhouse environment control air conditioners 4 can be grouped through the mobile terminal 1 for centralized control, and can also be pre-set through the mobile terminal 1, such as setting a constant temperature, dividing each day into several time periods, heating target temperature, cooling target temperature, timed shutdown time for the entire zone, timed startup time for the entire zone and other working parameters or operating parameters. Of course, on-site configuration can be performed through the mobile terminal 1 to set real-time temperature values, etc.

[0045] When the current working mode is set to the constant temperature mode through the mobile terminal 1, each greenhouse environment control air conditioner 4 will transmit the detected real-time temperature to the server 2. The server 2 calculates the average temperature based on all the received real-time temperatures, compares the average temperature with the constant temperature, and then controls each greenhouse environment control air conditioner 4 according to the comparison result to realize PID closed control, so that the entire area or a certain area is automatically in the constant temperature mode without manual adjustment.

[0046] When the current working mode is set to the custom mode through the mobile terminal 1, the server 2 can control the corresponding greenhouse environment control air conditioner 4 according to the wage parameters set on site or the preset operating parameters to achieve the customized operating effect.

[0047] Users can also use the mobile terminal1 to shut down and start the machine with one button, which simplifies the control and makes operation easier.

[0048] In the present invention, each greenhouse environment control air conditioner 4 can operate independently. In addition, a communication connection can also be established between each greenhouse environment control air conditioner 4, so that any greenhouse environment control air conditioner 4 can communicate with the server 2 to set the current working mode and operating parameters, making the use more flexible.

[0049] In summary, the mobile terminal centralized control system of the greenhouse environment control air conditioner of the present invention makes full use of the Internet of Things, cloud computing and sensor technology, connects the air conditioning equipment to the Internet, and solves the problem that conventional type equipment cannot maintain a constant temperature. The system can realize unattended control according to the instructions issued by the user from the mobile terminal, through server data collection and processing, and the temperature fluctuation range can be realized by ±1°C. The custom time-sharing control function greatly reduces the difficulty of integrated wiring through the Internet of Things technology, avoiding the problems of PLC being difficult to get started, relatively solidified programs, high costs, and inflexible configuration. Allow users to adjust the control environment temperature in time according to actual production needs, which is more efficient; compared with other traditional air conditioning equipment, it achieves significant advantages of good temperature control effect, manpower saving, and low deployment cost. In a production environment where different temperatures need to be set at different time periods, such as agricultural planting, it is necessary to control the ambient temperature at certain times to avoid losses caused by temperature changes and increase production. PLC or panel still cannot achieve the function of flexible control.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
