The indoor unit, the outdoor unit and the refrigerant distributor are controlled and distributed and adjusted by a centralized controller. At the same time, the refrigerant flow direction of the refrigeration and heating cycles is controlled, thereby making it possible for users to freely combine the indoor unit and the outdoor unit.

[0004] Some existing air-conditioning control systems work according to fixed parameters when controlling the air-conditioning and cannot reasonably adjust the air-conditioning power according to the real-time temperature, which further causes a waste of power resources. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an air-conditioning startup control system based on a terminal device, which solves the problem that reasonable power adjustment cannot be performed according to real-time temperature conditions, resulting in waste of electric power resources.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an air-conditioning startup control system based on a terminal device, comprising:

[0007] The parameter control and analysis unit is used to judge the start of the air conditioner according to the start temperature and indoor temperature transmitted by the start parameter acquisition unit, and generate a temperature monitoring signal and a control start signal, then analyze the control start signal, and compare the real-time indoor temperature according to the control standard to generate a stability monitoring signal and a stability analysis signal, and transmit the stability monitoring signal to the motor speed adjustment unit;

[0008] The motor speed regulating unit is used to process the acquired stable monitoring signal, generate a voltage compensation regulating signal and a speed analysis signal by judging the load of the motor current of the air-conditioning water pump, calculate the working power and the standard speed according to the control standard for the speed analysis signal, and judge the real-time speed to generate a speed increase regulating signal and a speed decrease regulating signal, and analyze and generate a stable monitoring signal;

[0009] The voltage compensation signal is analyzed, and the corresponding excitation current is adjusted according to the real-time motor current to generate adjustment information, and the adjustment information is transmitted to the control information output unit and the adjustment monitoring and analysis unit.

[0010] As a further solution of the present invention: it also includes an adjustment monitoring and analysis unit, which is used to monitor the acquired adjustment information, and generate a stable analysis signal and a secondary analysis signal by judging the real-time indoor temperature, and further adjust the real-time indoor temperature according to the secondary analysis signal to generate secondary adjustment information and transmit it to the control information output unit.

[0011] As a further solution of the present invention: the specific manner in which the parameter control and analysis unit generates the stable monitoring signal and the stable analysis signal is:

[0012] Acquire the real-time indoor temperature, and compare the real-time indoor temperature with the start-up temperature. If the real-time indoor temperature reaches the start-up temperature, generate a control start signal. If the real-time indoor temperature does not reach the start-up temperature, generate a temperature monitoring signal. Transmit the generated temperature monitoring signal to the control information output unit, and analyze the control start signal.

[0013] For the generated control start signal, the control standard is obtained, and the control range is specifically the temperature range interval. The air conditioner is started and adjusted according to the control standard. At the same time, the real-time indoor temperature after a time period t is obtained, and the real-time indoor temperature is compared with the control standard. If the real-time indoor temperature reaches the control standard, a stability analysis signal is generated. Otherwise, if the control standard is not reached, a stability monitoring signal is generated, and the generated stability analysis signal is transmitted to the motor speed adjustment unit.

[0014] As a further solution of the present invention: the specific method in which the motor speed regulating unit analyzes the stable monitoring signal is:

[0015] Obtain the real-time speed and motor current of the air conditioning water pump, and determine whether the motor current has a load. If the motor current has a load, a voltage compensation adjustment signal is generated. If the motor current has no load, a speed analysis signal is generated.

[0016] Based on the generated speed analysis signal, the control standard is obtained, and the working power of the water pump is calculated according to the minimum temperature in the control range. At the same time, the standard speed of the water pump is calculated according to the working power. Then the standard speed is compared with the real-time speed. If the real-time speed is greater than the standard speed, a speed reduction adjustment signal is generated. Conversely, if the real-time speed is less than the standard speed, a speed increase adjustment signal is generated.

[0017] As a further solution of the present invention: the motor speed regulating unit analyzes the speed increase regulating signal and the speed decrease regulating signal in a specific manner as follows:

[0018] The specific method of analyzing the generated speed reduction adjustment signal is: adjusting the real-time speed with the standard speed, generating adjustment information, and transmitting the adjustment information to the control information output unit;

[0019] The specific analysis method for analyzing the generated speed increase adjustment signal is: adjust the real-time speed with the standard speed, and obtain the adjusted working power as the real-time power, and monitor the real-time power. By analyzing the changes in the motor current, it is determined whether there is a load condition. If there is a load condition, a voltage compensation adjustment signal is generated. Otherwise, if there is no load condition, a stable monitoring signal is generated and transmitted to the adjustment monitoring and analysis unit.

[0020] As a further solution of the present invention: the specific manner in which the motor speed regulating unit analyzes the generated voltage compensation signal is:

[0021] The real-time motor current and the standard motor current are obtained, and the standard motor current here is represented as the motor current corresponding to the normal working condition, and the difference between the real-time motor current and the standard motor current is calculated, and the corresponding excitation current is adjusted at the same time, and the adjustment information is generated, and then the adjustment information is transmitted to the control information output unit.

[0022] As a further solution of the present invention: the specific manner in which the adjustment monitoring and analysis unit analyzes the adjustment information is as follows:

[0023] The air conditioner is adjusted according to the adjustment information, and the real-time indoor temperature is obtained and compared with the control standard. If the real-time indoor temperature meets the control standard, a stable analysis signal is generated. Otherwise, if the real-time indoor temperature does not meet the control standard, a secondary analysis signal is generated and further processed.

[0024] As a further solution of the present invention: the specific manner in which the adjustment monitoring and analysis unit processes the secondary analysis signal is:

[0025] Determine the real-time indoor temperature. If the real-time indoor temperature is greater than the control standard, and here it means that the real-time indoor temperature is greater than the maximum value of the control standard, a cooling signal is generated. Otherwise, a heating signal is generated. At the same time, the water pump speed is adjusted secondary according to the generated signal to further generate secondary adjustment information.

[0026] As a further solution of the present invention: it also includes a startup parameter acquisition unit and a control information output unit;

[0027] A startup parameter acquisition unit, used to transmit the acquired startup information to the parameter control and analysis unit, and the startup information includes the startup temperature and the indoor temperature;

[0032] Figure 2 This is a diagram of the cooling water pump control scheme of the present invention. DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] For example, see Figure 1 and Figure 2 The present application provides an air-conditioning startup control system based on a terminal device, including: a startup parameter acquisition unit, a parameter control analysis unit, a motor speed adjustment unit, an adjustment monitoring and analysis unit, and a control information output unit.

[0035] The startup parameter acquisition unit is used to acquire startup information and transmit the startup information to the parameter control and analysis unit, wherein the startup information includes the startup temperature and the indoor temperature.

[0036] The parameter control analysis unit is used to analyze the acquired startup information, and the specific analysis method is as follows:

[0037] The indoor temperature is monitored in real time, measured by the corresponding temperature sensor, and compared with the preset start temperature threshold. When the real-time indoor temperature reaches or exceeds the start temperature, the system will automatically generate a control start signal. On the contrary, if the real-time indoor temperature is lower than the start temperature, the system will generate a temperature monitoring signal. The temperature monitoring signal will then be transmitted to the control information output unit, and the system will conduct in-depth analysis of the generated control start signal.

[0038] Once the control start signal is generated, the system immediately calls the control standard. The control standard here is the indoor temperature range preset by the operator. Based on this standard, the system starts and adjusts the air conditioner accordingly. After the set time period t, the system will obtain the real-time indoor temperature again and compare it with the control standard;

[0039] If the real-time indoor temperature after time period t has entered the preset temperature range, the system will generate a stable analysis signal, indicating that the indoor temperature has reached a stable control state. On the contrary, if the real-time indoor temperature has not yet entered the control standard range, a stable monitoring signal will be generated, indicating that the indoor temperature needs to be continuously monitored and adjusted until the control standard is reached.

[0040] The motor speed regulating unit is used to analyze and process the acquired stable monitoring signal, and the specific analysis and processing method is as follows:

[0041] The system collects the speed data and motor current information of the air conditioning water pump in real time. With this data, the system can evaluate whether the motor is under load. Specifically, if the motor current is detected to indicate that there is a load, the system will generate a motor power supply analysis signal to further analyze the motor power supply and its impact on system performance. On the contrary, if the motor current shows no load, the system will generate a speed analysis signal to evaluate the operating efficiency of the water pump and possible optimization measures.

[0042] Faced with the generated speed analysis signal, the system will first refer to the control standard for adjustment. This control standard covers the minimum threshold of temperature control. Based on this threshold, the system will calculate the working power of the water pump. Then, based on the working power of the water pump, the system will further calculate the standard speed of the water pump.

[0043] Next, the system will compare this standard speed with the current real-time speed of the water pump. If it is found that the real-time speed exceeds the standard speed, the system will generate a speed reduction adjustment signal to indicate that the water pump speed needs to be reduced to optimize energy consumption and system operating efficiency. On the contrary, if the real-time speed is lower than the standard speed, the system will generate a speed increase adjustment signal, indicating that the water pump speed needs to be increased to ensure that the temperature control reaches the predetermined standard.

[0044] The specific method of analyzing the generated speed reduction adjustment signal is: adjusting the real-time speed with the standard speed, generating adjustment information, and transmitting the adjustment information to the control information output unit;

[0045] The specific method of analyzing the generated speed increase adjustment signal is as follows: the system will adjust the real-time speed of the water pump according to the standard speed. After the adjustment is completed, the system will record and monitor the adjusted real-time power. At the same time, by analyzing the changes in the motor current, the system can determine whether the motor is loaded. If the analysis results show that there is a load, the system will generate a voltage compensation adjustment signal to adapt to the power demand changes caused by the load. This signal will guide the system to make necessary voltage adjustments to ensure that the motor can operate at the optimal voltage level to avoid performance degradation or damage caused by insufficient voltage;

[0046] Conversely, if the motor current analysis results indicate that there is no load present, the system will generate a stability monitoring signal. This indicates that the motor and pump are operating stably without additional load, and no further voltage adjustment is required. The system will continue to operate in the current state and continuously monitor to maintain operational stability and efficiency.

[0047] The system will conduct in-depth analysis of the generated voltage compensation signal to ensure that the motor can operate in an optimal state. First, the system will obtain real-time motor current data and compare it with the standard motor current, which is the expected motor current value under normal working conditions.

[0048] By calculating the difference between the real-time motor current and the standard motor current, the system can determine the magnitude and direction of the excitation current that needs to be adjusted. This adjustment is to ensure that the motor can operate at the optimal efficiency point while avoiding overload or underload operation.

[0049] Combined with actual analysis, there are many ways to change the excitation current, including adjusting the output voltage of the excitation device, adjusting the parameters of the power amplifier circuit, and using an intelligent controller for precise control;

[0050] Adjust the output voltage of the excitation device, for example in the following ways:

[0051] The thyristor rectifier system is the most common excitation device. It adjusts the output voltage by changing the trigger angle of the thyristor, thereby changing the excitation current.

[0052] Automatic excitation regulator: This type of regulator can automatically adjust the excitation current according to the generator load and the needs of the power system to control the terminal voltage and reactive power distribution of the generator;

[0053] Adjust the power amplifier circuit parameters, such as the following methods:

[0054] Control phase-shift pulse: In the digital excitation regulator, the output of the three-phase fully controlled rectifier bridge can be adjusted by controlling the phase-shift pulse, thereby changing the excitation current.

[0055] Synchronous and digital trigger control circuits: These circuits ensure that the control signal is synchronized with the phase of the AC power supply, achieving accurate triggering of multiple thyristors and thus finely regulating the excitation current.

[0056] Use smart controllers for precise control, such as the following:

[0057] PI C16F877 single-chip microcomputer: This microcontroller integrates multiple A / D converters and peripheral device modules, which can directly collect analog signals such as voltage and current during the operation of the generator, and perform real-time calculations and logical judgments to achieve precise control of the excitation current.

[0058] CPU control module: As the control core of the excitation regulator, it can efficiently execute complex control algorithms and flexibly adjust the excitation current to adapt to different operating conditions.

[0059] A control information output unit is a functional unit used to transmit the acquired adjustment information and stability analysis signal to the terminal device.

[0060] Embodiment 2, as Embodiment 2 of the present invention, is implemented on the basis of Embodiment 1, and differs from Embodiment 1 in that.

[0061] The motor speed regulating unit transmits the generated regulating information to the regulating monitoring and analyzing unit, and the regulating monitoring and analyzing unit analyzes the regulating information, and the specific analysis method is as follows:

[0062] Based on the adjustment information received, the system will adjust the operating parameters of the air conditioner accordingly to ensure more accurate temperature control. At the same time, the system continuously monitors the real-time indoor temperature and compares it with the preset control standard. If the real-time indoor temperature is within the control standard range, the system generates a temperature monitoring signal, indicating that the current temperature control is effective and continues to maintain stable operation. On the contrary, if the real-time indoor temperature deviates from the control standard, the system will generate a secondary analysis signal.

[0063] The system will continuously evaluate the real-time indoor temperature and compare it with the control standard. The control standard is defined here as an ideal temperature range, including maximum and minimum values. If the real-time indoor temperature is found to exceed the maximum value of the control standard, the system will generate a cooling signal, which indicates that measures need to be taken to reduce the indoor temperature to return to the control standard range. On the contrary, if the real-time indoor temperature is lower than the minimum value of the control standard, the system will generate a heating signal, indicating that the indoor temperature needs to be increased;

[0064] Based on these generated signals, the system will make secondary adjustments to the pump speed. By accurately adjusting the pump speed, the temperature output of the air conditioning system can be effectively controlled, thereby achieving precise adjustment of the indoor temperature. After the adjustment is completed, the system will generate secondary adjustment information.

[0065] And the regulated water pump and motor current will continue to be monitored for the generated secondary adjustment information, and the monitoring method is the same as the monitoring method in the first embodiment.

[0066] A control information output unit is used to transmit the acquired secondary adjustment information to the terminal device.

[0067] Embodiment 3, as the embodiment 3 of the present invention, focuses on combining the implementation processes of embodiment 1 and embodiment 2 for implementation.

[0068] Some of the data in the above formulas are dimensionless and numerically calculated. Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0069] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
