Description
Technical Field
The invention relates to a method for forming multi-gear control based on a few physical gears and a direct current brushless motor.
Background
In general, a motor is used for driving a fan of an air conditioner, the output air volume of the fan is divided into a plurality of levels, so that the motor is required to have a plurality of gear rotating speeds, and the rotating speed operation of the plurality of gears depends on the gear detection circuit in a motor controller to identify the instruction requirement of a load.
Currently, the most common methods are: the motor controller is provided with a plurality of physical gear detection circuits, the physical gear detection circuits receive a control instruction of a load and input a signal into a microprocessor MCU of the motor controller, and the motor controller selects the rotating speed of one gear to control the motor to operate according to the signal of the physical gear detection circuits. Only one physical gear detection circuit in the plurality of physical gear detection circuits is connected with the signal source at each time, and the other physical gear detection circuits are disconnected. Such an arrangement has the following disadvantages: because every physics gear detection circuit all is connected with a microprocessor MCU's an I/O mouth, the quantity of physics gear detection circuit can not be too much, leads to the quantity of the gear rotational speed of chooseing limited, and the quantity of physics gear detection circuit also is more, and part number is many, and the cost increases, and occupies more microprocessor MCU's I/O mouth.
The simplest method is to simultaneously switch on a plurality of physical gears to generate a new gear, so that the input signal specification of each gear (comprising a plurality of physical gear combinations) is the same, the traditional 24VAC 60Hz signal can be utilized, hardware change of the main control board is less, and the cost is lower. For example, a 5-gear (physical gear) electric machine, in principle 2 can be realized in this way 5 -1 = 31 gears.
At present, in a large factory in the air conditioning industry, a 5 × 2 connector is adopted, and a load of 9 gears is realized through a combination of a plurality of (5) physical gears. From this it can prove, produce more input gears with few physics gear detection circuit, not only have the needs of motor producer, also have market demand: one of the benefits of this is that fewer motor part numbers can be used to cover more load models (because of the different number of gears, each model of load originally corresponds to a certain model of motor); the second advantage is that more gears are provided in the same load for users to select, and more air volume selections are provided according to different ventilation pipeline laying on the site of the users, so that the novel ventilation pipeline is a good selling point.
However, the combination of the above physical gear detection circuits realizes control of more gear inputs, and still cannot meet the requirement, that is, the number of gears generated under the condition of the same number of physical gear detection circuits is not enough, for example: a3 physical gear detection circuits (A, B and C are assumed) can form 7 gears at most according to the traditional method (namely 7 combinations of A, B, C, AB, AC, BC, ABC and the like). Thus, U.S. patent nos.: US20210355951A1 shows a method of generating at least 17 gears using 4 physical gear detection circuits using a combination of two signal sources, 24VAC 60Hz and 24VAC 120Hz. However, this brings a trouble, it is necessary to provide two signal sources of 24VAC 60Hz and 24VAC 120Hz, which are obtained by converting 120VAC, and the selection and cost of 120VAC as a signal source is higher than those of 24VAC as a signal source in PCB related components, and not all loads have an existing 120VAC signal source available, and additional components must be added.

Detailed Description
The present invention will be described in further detail below with reference to specific embodiments and accompanying drawings.
The first embodiment is as follows:
as shown in fig. 1 and fig. 2, the present embodiment provides a method for forming multi-gear control based on a small number of physical gears, including N physical gear detection circuits and a microprocessor MCU, where only 3 physical gear detection circuits are shown in the figure, but not limited to 3 physical gear detection circuits, and may be 2 or 4 or 5 physical gear detection circuits, an output terminal of each physical gear detection circuit is connected to an I/O port of the microprocessor MCU, and an input terminal of each physical gear detection circuit is connected to a single signal source S, which is characterized in that: the microprocessor MCU identifies whether each physical gear detection circuit is connected with a signal source S or not through input signals of N physical gear detection circuits, if at least two physical gear detection circuits are connected with the signal source S, the sequence and the delay time t of the connection of each physical gear detection circuit with the signal source are also recorded, and M gear controls (namely M logic gear inputs) are generated by using output signals and the delay time of each physical gear detection circuit, wherein M is larger than N, and N and M are integers.
According to the invention, on the premise of a single signal source, namely that customers are not required to provide more signal sources and change the circuit structure, more gear control is generated through a few physical gear detection circuits, more load models are covered by fewer motor part numbers, the production management is convenient, the circuit structure is simple, the manufacturing cost is low, the requirements of more gear control of the load are met, and the application range is widened.
The recording of the sequence of turning on the signal source by each physical gear detection circuit is realized by the time point of turning on the signal source by each physical gear detection circuit, for example: assuming that the time point when the first physical gear detection circuit is connected to the signal source S is t01, and the time point when the second physical gear detection circuit is connected to the signal source S is t02, comparing the two time points t01 and t02 can know which physical gear detection circuit is connected to the signal source S first, and the difference between the two time points t01 and t02 is the connection delay time of the first physical gear detection circuit and the second physical gear detection circuit.
In fig. 1 and 2, N1 represents an input signal of the first physical gear detection circuit; n2 represents an input signal of a second physical gear detection circuit; n3 represents an input signal of a third physical gear detection circuit, and the input signal N1 forms an output signal IO1 after passing through the first physical gear detection circuit and enters an I/O of the microprocessor MCU; the input signal N2 forms an output signal IO2 after passing through a second physical gear detection circuit and enters a second I/O of the microprocessor MCU; and the input signal N3 forms an output signal IO3 after passing through a third physical gear detection circuit and enters a third I/O of the microprocessor MCU. And the microprocessor MCU identifies whether each physical gear detection circuit is connected with the signal source S or not through input signals of the N physical gear detection circuits.
In fig. 2, the physical gear detection circuit is an optical coupling isolation circuit, and the first physical gear detection circuit includes a resistor R1, a resistor R2, a resistor R3, a capacitor C1, a zener diode D1, and an optical coupling chip U1; the second physical gear detection circuit comprises a resistor R4, a resistor R5, a resistor R6, a capacitor C2, a voltage stabilizing diode D2 and an optocoupler chip U2; the third physical gear detection circuit comprises a resistor R7, a resistor R8, a resistor R9, a capacitor C3, a voltage stabilizing diode D3 and an optocoupler chip U3;
as shown in fig. 1, when the switch K1 is pressed, the first physical gear detection circuit turns on the signal source S, the input signal N1 passes through the first physical gear detection circuit to form an output signal IO1 which is a high-level signal, and when the switch K1 is turned off, the output signal IO1 is a low-level signal; when the microprocessor MCU receives the IO1 signal with high level, recording the time; when the switch K2 is pressed, the second physical gear detection circuit is connected with the signal source S, the input signal N2 passes through the second physical gear detection circuit to form an output signal IO2 which is a high-level signal, and when the switch K2 is disconnected, the output signal IO2 is a low-level signal; when the microprocessor MCU receives the IO2 signal with high level, recording the time; when the switch K3 is pressed, the third physical gear detection circuit is connected with the signal source S, the input signal N3 passes through the third physical gear detection circuit to form an output signal IO3 which is a high-level signal, and when the switch K3 is disconnected, the output signal IO3 is a low-level signal; when the microprocessor MCU receives the signal that IO3 is high level, and records the time.
Taking fig. 1 and fig. 2 as an example, 3 physical gear detection circuits are included, the microprocessor MCU detects each I/O port connected to the physical gear detection circuits, when a certain physical gear detection circuit is connected to a signal source, the input signal of the I/O port is a high level signal and records time, the microprocessor MCU generates M gear controls as follows:
a) Only one physical gear detection circuit in the 3 physical gear detection circuits is connected with a signal source, and then 3 gear control signals are formed;
b) At least two physical gear detection circuits in the 3 physical gear detection circuits are connected with a signal source, and 4 combined gear control signals are formed without considering the time delay connection;
c) At least two physical gear detection circuits in the 3 physical gear detection circuits are connected with a signal source, and 12 combined gear control signals can be formed under the condition of considering the time of delayed connection;
m =3+4+12= 19.
The method is realized by identifying the delay time of each physical gear detection circuit for switching on a signal source: assuming that the switch control signal of the input motor is not changed, or the traditional 24VAC 60Hz signal, more gears can be generated by combining a plurality of physical gear detection circuits of the connected signal source, and except the physical gear detection circuit of the first connected signal source, the physical gear detection circuits of the other connected signal sources are started in a delayed mode. Each physical gear detection circuit is represented by a lower case letter T1, T2 \8230, tn, and an input gear generated by the physical gear detection circuit is represented by a capital letter T, such as T1, T2, \8230, tn, and the like. And the physical gear of delayed start is represented by t1d, t2d, \8230andtnd. Where d denotes the second gear being actuated within a certain defined time after the actuation of the first physical gear, this "defined time" being a reasonably short period of time that allows the motor controller to correctly identify the time for the delayed actuation, for example in the range of 1 to 5 seconds.
Similarly, 19 input gear positions can be realized by 3 physical gear position detection circuits, and the combination logic is as follows:
T1 = t1
T2 = t2
T3 = t3
T4 = t1 + t2
T5 = t1 + t3
T6 = t2 + t3
T7 = t1 + t2 + t3
T8 = t1 + t2d
T9 = t1 + t3d
T10 = t2 + t1d
T11 = t2 + t3d
T12 = t3 + t1d
T13 = t3 + t2d
T14 = t1 + t2 + t3d
T15 = t1 + t3 + t2d
T16 = t2 + t3 + t1d
T17 = t1 + t2d + t3d
T18 = t2 + t1d + t3d
T19 = t3 + t1d + t2d
similarly, 5 input gears can be realized by 2 physical gear detection circuits, and the combination logic is as follows:
T1 = t1
T2 = t2
T3 = t1 + t2
T4 = t1 + t2d
T5 = t2 + t1d
a flow chart of a specific program in a microprocessor MCU (microprogrammed control unit) for realizing 5 input gears by 2 physical gear detection circuits is shown in figure 3; the microprocessor MCU initializes variables and an I/O port; detecting whether a first physical gear detection circuit is connected with a signal source S, if so, outputting a signal IO1 which is a high-level signal by the physical gear detection circuit and recording the initial time of connection; if not, the output signal IO1 is a low level signal and is in a standby state; detecting whether a second physical gear detection circuit is connected with a signal source S, if so, outputting a signal IO2 of the physical gear detection circuit to be a high-level signal and recording the initial time of connection; if not, the output signal IO2 is a low level signal and is in a standby state. And (3) judging by the MCU combinational logic:
a) Only one physical gear detection circuit in the 2 physical gear detection circuits is connected with a signal source, and then 2 gear control signals are formed; i.e. generating T1, T2 gears, i.e. T1 = T1, T2 = T2;
b) At least two physical gear detection circuits in the 2 physical gear detection circuits are connected with a signal source, and under the condition that time delay connection is not considered, 1 combined gear control signal is formed, namely T3= T1+ T2;
c) At least two physical gear detection circuits in the 2 physical gear detection circuits are connected with a signal source, and under the condition of considering the time of delayed connection, 2 combined gear control signals are formed, namely T4 = T1+ T2d and T5 = T2 + T1d; wherein, T4 = T1+ T2d means that the two physical gear detection circuits are both connected to the signal source, but the first physical gear detection circuit is connected to the signal source first, the second physical gear detection circuit is connected to the signal source later, and the two circuits are connected to the signal source to form Delay time, and the Delay time Delay2 is more than 4 seconds, then the microprocessor MCU selects the gear T4; the table T5 = T2 + T1d means that both the two physical gear detection circuits are connected to the signal source, but the signal source is connected after the first physical gear detection circuit, the signal source is connected first by the second physical gear detection circuit, and the Delay time is formed when both the two physical gear detection circuits are connected to the signal source, and the Delay time Delay1 is greater than 4 seconds, then the microprocessor MCU selects the gear T5. In the flowchart of fig. 3, the Delay times Delay2 and Delay1 are limited to 4 seconds, but the Delay times Delay2 and Delay1 may be set to 2 seconds as appropriate.
