Fig. 1 is a schematic diagram of a computer board of a water heater in the prior art, as shown in fig. 1, the computer board of the water heater generally includes two parts, namely a control unit and a power output unit, where the control unit plays a role in displaying and controlling by being connected to a display unit, and exemplarily, the control unit and the display unit are integrated together to form a display operation board, and the display operation board can be used for displaying information for a user, receiving a user instruction, and correspondingly controlling the water heater according to the user instruction. One end of the power output unit is connected with 220V household electricity, and the other end of the power output unit outputs a low-voltage power supply, so that the functions of power transformation, load control and the like are achieved. The power output unit is connected with the water pump controller, in a possible mode, the power output unit and the water pump controller are integrated together, the water pump controller is connected with the control unit, and the water pump controller can control the water pump of the water heater and change the flow of the water pump by receiving a control instruction sent by the control unit, so that the functions of switching on and off, temperature regulation and the like of the water heater are realized.
In the prior art, a water pump controller is generally designed and implemented by two types, one type is a relay, the relay is an electric control device, and the electric control device is an electric appliance which enables a controlled quantity to generate a predetermined step change in an electric output circuit when the change of an input quantity (excitation quantity) meets a specified requirement. It has an interactive relationship between a control system (also called an input loop) and a controlled system (also called an output loop). It is commonly used in automated control circuits, which are actually a "recloser" that uses low current to control high current operation. Therefore, the circuit plays the roles of automatic regulation, safety protection, circuit conversion and the like. The other type is a thyristor, which is a short name for a thyristor rectifier element, and is a high-power semiconductor device with a four-layer structure of three PN junctions, also called a thyristor. The semiconductor device has the characteristics of small volume, relatively simple structure, strong function and the like, and is one of the more commonly used semiconductor devices. The device is widely applied to various electronic equipment and electronic products, and is mainly used for controllable rectification, inversion, frequency conversion, voltage regulation, contactless switches and the like. Compared with a relay, the silicon controlled rectifier has the advantages of higher response speed, better performance and higher cost. In different products, silicon controlled rectifiers and relays are common implementation schemes of water pump controllers according to different product requirements.
However, because the control methods of the relay and the thyristor are different, the types of the control signals are different, and different control units are required to control, so in the prior art, different control units are usually configured for the relay and the thyristor respectively, and therefore, in the process of producing the water heater, two different display operation panels need to be produced, a control unit matched with the relay and a control unit matched with the thyristor are respectively arranged, and because the control units have no universality, the production cost and the management cost of the display operation panels are increased, and the reliability is reduced.
The following describes the technical solution of the present invention and how to solve the above technical problems in detail by specific examples. These several specific embodiments may be combined with each other below, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 2 is a flowchart of a computer board control method according to an embodiment of the present invention, where the computer board control method according to the embodiment is applied to a control unit of a water heater, the water heater further includes a power output unit and a water pump controller, the control unit is respectively connected to the power output unit and the water pump controller, and the power output unit is connected to the water pump controller, as shown in fig. 2, the computer board control method according to the embodiment includes the following steps:
and S101, acquiring an adaptation signal sent by the power output unit, wherein the adaptation signal represents the type of a water pump controller connected with the power output unit.
In a possible implementation manner, after the water heater is powered on, the power output unit in the water heater is powered on, and here, the power output unit sends a signal, namely an adaptation signal, to the control unit. When the power output unit is connected with different water pump controllers, the types of the adaptation signals sent to the control unit are different, for example, when the water pump controller is a relay, the adaptation signals sent to the control unit by the power output unit are high-level signals, and when the water pump controller is a silicon controlled rectifier, the adaptation signals sent to the control unit by the power output unit are pulse signals.
And step S102, determining the type information of the control signal according to the adaptation signal.
When the control unit controls the water pump controller, the control signals used by different water pump controllers are different, specifically, in order to reduce the problem of self-heating of the silicon controlled rectifier, the control signal sent to the silicon controlled rectifier by the general control unit is a pulse control signal, and the control signal sent to the relay by the control unit is a high/low level control signal. And the adaptation signal is information that characterizes the type of water pump controller. When the type information of the control signal is determined according to the adaptation signal, the signal characteristic of the adaptation signal is determined by carrying out signal analysis on the adaptation signal, and then the signal characteristic of the control signal is determined according to the consistency corresponding relation between the adaptation signal and the control signal according to the signal characteristic of the adaptation signal, so that the type information of the control signal is determined. The type information is used for characterizing the type of the control signal, such as a pulse control signal or a high-low level control signal.
And step S103, sending a control signal of a corresponding type to the water pump controller according to the type information of the control signal, so that the water pump controller adjusts the flow rate of the water pump according to the control signal.
Fig. 3 is a schematic diagram of a computer board of a water heater provided in an embodiment of the disclosure, and as shown in fig. 3, the control unit may include two or more signal sending ports for sending different types of control signals to the water pump controller to adapt to different water pump controllers. After determining the type information of the control signal, the control unit sends a control signal of a matched type to the water pump controller through the corresponding signal sending port according to the type of the water pump controller represented by the type information, as shown in fig. 3, and according to the adaptation signal, the control unit sends the control signal of the matched type to the water pump controller through the signal sending port 2. Therefore, the control unit can control the water pump controllers of different types, and the control unit has the generalization characteristic. After the control unit and the display unit are integrated into the display operation board, the control unit in the display operation board can be adapted to different types of water pump controllers, so that the display operation board can also be used as a universal part to be adapted to water heaters with different water pump controllers, and the universality of a computer board of the water heater is improved.
The computer board control method provided by the embodiment is applied to a control unit of the water heater, the water heater further comprises a power supply output unit and a water pump controller, the control unit is respectively connected with the power supply output unit and the water pump controller, and the power supply output unit is connected with the water pump controller. The method comprises the steps that adaptation signals sent by a power output unit are obtained, wherein the adaptation signals represent the type of a water pump controller connected with the power output unit; determining type information of the control signal according to the adaptation signal; and sending a control signal of a corresponding type to the water pump controller according to the type information of the control signal so that the water pump controller regulates the flow of the water pump according to the control signal. After the adaptation signal sent by the power output unit is received, the specific type of the water pump controller can be determined according to the adaptation signal, and then the corresponding control signal is sent according to the specific type, so that the control unit of the computer board can be matched with the power output units of different types, the universality of the control unit is improved, the production and management cost of the computer board is reduced, and the reliability of equipment is improved.
Fig. 4 is a flowchart of a computer board control method according to another embodiment of the present invention, and as shown in fig. 4, the computer board control method provided in this embodiment further details S101-S102 on the basis of the computer board control method provided in the embodiment shown in fig. 2, and then the computer board control method provided in this embodiment includes the following steps:
step S201, acquiring an adaptation signal sent by the power output unit.
For example, when the power output units are different, the transmitted adaptation signals are also different, for example: if the type of the water pump controller connected with the power output unit is a relay, receiving a high-low level signal sent by the power output unit; and if the type of the water pump controller connected with the power output unit is controlled silicon, receiving a pulse signal sent by the power output unit.
In a possible implementation manner, the water pump controller connected to the power output unit is a thyristor, the power output unit includes a zero-crossing detection subunit, and the acquiring of the adaptation signal sent by the power output unit includes: receiving a zero-crossing detection signal sent by a zero-crossing detection subunit; and determining an adaptation signal according to the zero-crossing detection signal. In the scene that the water pump controller is the silicon controlled rectifier, because the self characteristic of the silicon controlled rectifier needs to be provided with the zero-crossing detection circuit, namely the zero detection subunit, the control unit can directly use the zero-crossing detection signal output by the zero-crossing detection circuit as the adaptation signal to determine the type of the control signal, so that a special circuit does not need to be additionally arranged on the power output unit to output the adaptation signal, and the circuit cost is reduced.
Step S202, the adaptation signals are analyzed, and the signal characteristics of the adaptation signals are determined.
In step S203, if the signal characteristic is a pulse signal characteristic, it is determined that the type information of the control signal is a pulse control signal.
In step S204, if the signal characteristic is a high-low level characteristic, it is determined that the type information of the control signal is a high-low level control signal.
Illustratively, after receiving the adaptation signals, different adaptation signals have different signal characteristics, specifically, the signal characteristics include time domain characteristics and/or frequency domain characteristics, and for different adaptation signals, the corresponding time domain characteristics and/or frequency domain characteristics are different, for example, the time domain characteristics and the frequency domain characteristics between a pulse signal and a high-low level signal are different, and the signal characteristics of the adaptation signals can be determined by performing time domain analysis and frequency domain analysis on the adaptation signals.
Further, after the signal characteristic is determined, according to the principle that the adaptation signal is consistent with the control signal, the type of the control signal corresponding to the signal characteristic of the adaptation signal can be determined, for example, if the signal characteristic is a pulse signal characteristic, the control signal is a pulse control signal; the signal characteristic is a high-low level signal characteristic, and the control signal is a high-low level control signal.
And step S205, if the signal characteristic is not the pulse signal characteristic or the high-low level characteristic, outputting alarm information.
In a possible implementation manner, if the signal characteristic is not the pulse signal characteristic or the high-low level characteristic, an error adaptation signal may be generated due to a circuit problem, and at this time, the control unit outputs alarm information to avoid a safety problem caused by the control unit sending an error type of control signal. Specifically, the control unit can output alarm information through a display unit connected with the control unit, or broadcast the alarm information through a prompt tone through a sound production unit connected with the control unit, and the control unit is not specifically limited here.
And step S206, sending a control signal of a corresponding type to the water pump controller according to the type information of the control signal, so that the water pump controller adjusts the flow rate of the water pump according to the control signal.
In this embodiment, the implementation manner of step S206 is the same as the implementation manner of step S103 in the embodiment shown in fig. 2 of the present invention, and is not described in detail here.
