Detailed ways:

The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

Embodiment one:

As shown in Figure 1 and Figure 2, a blower system (such as an air conditioner) is installed in a typical ventilation duct (referred to as the air duct). There is an air filter, and when the motor is started, it starts to blow air. Since the number of air outlets and air inlets is related to the number of rooms, there is no uniform standard for the design of the pipeline. At the same time, the air filter may have different pressure drops. If you want to obtain a constant The air volume must have a good technical solution.

An air conditioner of the present invention includes a motor, a wind wheel, a power supply and a system controller. The system controller has a main control circuit board that realizes the functions of the electrical equipment itself. The main control circuit board drives the motor to drive the wind wheel to rotate, wherein: the The motor unit is a motor unit without a controller, including a shaft, a permanent magnet rotor assembly, a stator assembly, and a casing assembly. Permanent magnets are installed on the permanent magnet rotor assembly, and the permanent magnet rotor assembly and the stator assembly form a magnetic coupling. , the stator assembly includes a stator core and a coil winding wound on the stator core; the main control circuit board is arranged with a system microprocessor, an inverter circuit and a motor operating parameter detection circuit, and the operating parameter detection circuit connects the motor The real-time operating parameters are input to the system microprocessor, the output terminal of the system microprocessor controls the inverter circuit, and the output terminal of the inverter circuit is connected with the coil winding.

As shown in Figure 3 and Figure 4, the above-mentioned motor is a motor unit 1, and the described motor unit 1 includes a stator assembly 12, a rotor assembly 13 and a casing assembly 11, the stator assembly 13 is installed on the casing assembly 11, and the motor The monomer 1 is equipped with a Hall sensor 14 (rotor position measurement circuit) for detecting the rotor position. The rotor assembly 13 is set on the inside or outside of the stator assembly 12. The rotor position measurement circuit detects the rotor position signal and inputs it to the system microprocessor. The bus current detection circuit inputs the detected bus circuit to the system microprocessor, the bus voltage detection circuit inputs the DC bus voltage to the system microprocessor, the system microprocessor controls the inverter circuit, and the inverter circuit controls each phase of the stator assembly 12 Coil winding on and off. The rotor position measurement circuit, the bus current detection circuit and the bus voltage detection circuit are part of the motor operation parameter detection circuit.

As shown in Fig. 5 and Fig. 6, assuming that the PM motor is a 3-phase brushless DC permanent magnet synchronous motor, the rotor position measurement circuit 14 generally uses 3 Hall sensors, and the 3 Hall sensors respectively detect a 360-degree electrical angle cycle The position of the rotor changes the energization of the coil windings of each phase of the stator assembly 12 every time the electrical angle of 120 degrees is turned, forming a 3-phase 6-step control mode. After the AC input (AC INPUT) passes through the full-wave rectification circuit composed of diodes D7, D8, D9, and D10, the DC bus voltage Vbus is output at one end of the capacitor C1. The DC bus voltage Vbus is related to the input AC voltage, and the AC input ( After the voltage of AC INPUT) is determined, the line voltage UP of the 3-phase winding is the PWM chopper output voltage, UP=Vbus*w, w is the duty cycle of the PWM signal input from the system microprocessor to the inverter circuit, changing the line voltage UP can change the DC bus current Ibus. The inverter circuit is composed of electronic switch tubes Q1, Q2, Q3, Q4, Q5, and Q6. The control terminals of the electronic switch tubes Q1, Q2, Q3, Q4, Q5, and Q6 are controlled by the microprocessor The output is controlled by 6 PWM signals (P1, P2, P3, P4, P5, P6). The inverter circuit is also connected to the resistor R1 to detect the bus current Ibus. The bus current detection circuit converts the detected bus current Ibus of the resistor R1 and then transmits to the system microprocessor. The motor input power control is controlled by the electronic switch tube Q7, and a PWM signal output by the microprocessor, that is, P0, controls the conduction time of the electronic switch tube Q7 to control the input power of the motor. The motor input power is equal to the DC bus current Ibus multiplied by the DC bus voltage Vbus. The rotational speed of the motor and the signals detected by the Hall sensor are calculated respectively.

Assuming that a constant air volume control unit is established in the system microprocessor, the constant air volume control unit sets the control function P=f(n) of the constant air volume, where P is the input power of the motor, and n is the motor running speed, and the control function P=f of the constant air volume (n) is obtained in this way: first collect the original data, and adjust from low static pressure to high static pressure for at least one target air volume. This static pressure must cover the actual static pressure range of the application. During the process of adjusting the static pressure In , let the motor be under constant speed control, and keep the air volume as the target air volume by adjusting the motor speed n and the real-time input power Pi of the motor, and record the steady-state speed n of the motor at this time and the corresponding real-time input power Pi of the motor. In this way, for a certain For each target air volume, a set of rotational speed n and the real-time input power Pi of the motor are generated, and then a number of target air volumes are generated by the method of curve fitting, and each target air volume corresponds to a function P=f(n). The constant air volume control function relation P=f(n) can be a second-order function: P=C ₁ +C ₂ ×n+C ₃ ×n ² , the specific derivation process can be found in the patent announcement number applied by our company in 2014 CN104180858A. Name: a method for measuring air volume by a fan motor, which describes in detail how to establish a control function P=f(n) for constant air volume. As long as the two parameters of the speed n and the real-time input power Pi of the motor are controlled, the constant air volume control can be realized.

The following shows the experimental data of our test output air volume of 1200CFM.

The curve fitting diagram shown in FIG. 7 was established using the above-mentioned table. The control function P=f(n) of constant air volume is obtained. Using the constant air volume control function P=f(n) can make the motor work in the constant air volume mode. As for the constant speed mode of the motor, it has been described in detail in many patent documents at home and abroad, and will not be described in detail here.

The above determination of whether the air conditioner is in the sweeping state can be determined by detecting the two parameters of the input power and the rotational speed of the motor. When the input power and speed change periodically, and the change range is relatively large, the air conditioner is considered to be in the sweeping state; when the input power and speed change periodically, or the change range is small, the air conditioner is determined not to be in the sweeping state; As mentioned above, when the motor is working in the constant air volume mode, it is judged whether the air conditioner is in the sweeping state by detecting the two parameters of the motor input power and speed; Whether it is in sweeping state. The current value can be the DC bus current Ibus. If the DC bus current Ibus shows periodic changes, it is determined that the air conditioner is in the sweeping state; if the DC bus current Ibus shows non-periodic changes, it is determined that the air conditioner is not in the sweeping state. The motor enters the constant speed working mode from the constant air volume working mode, and the speed V selected to enter the constant speed working mode is equal to the sum of the maximum and minimum speed fluctuations when the air conditioner is in the sweeping state and the motor is in the constant air volume working mode, and then divided by 2 , to get an average speed.
