At present, with the development of modern industry, a large number of electronic devices are widely applied to the solenoid valve. The electromagnetic valve is an industrial technology controlled by electromagnetism, is an automatic basic element for controlling fluid, belongs to an actuator, and is not limited to hydraulic pressure and pneumatics. It is a valve body composed of electromagnetic coil and magnetic core, and containing one or several holes. When the coil is energized or de-energized, the operation of the core will cause the fluid to pass through the valve body or be cut off, achieving the purpose of changing the direction of the fluid.
The induction flushing electromagnetic valve used for controlling the size flushing in the market is mostly powered by single voltage, cannot adapt to various common power supply modes, such as 5V adapter power supply, 4.5V (3 dry batteries) batteries or 3.6V lithium sub-batteries and the like, cannot provide various choices for customers, and is limited in application range. The conventional automatic identification mode of the power supply is that after the main control board is powered on, the voltage value of the power supply input by direct sampling detection is directly identified, such as the power supply mode of 3.6V or 4.5V. The power source identification method has the disadvantage that the voltage of a high-voltage old battery (such as 3 old dry batteries with the voltage of only 3.4V) can be overlapped with the voltage of a new low-voltage battery (such as 3.6V of a new lithium sub-battery), so that the voltage cannot be identified.

The invention is described in further detail below with reference to the following figures and specific examples.
Detailed Description
The invention is further described below by means of specific embodiments.
Referring to fig. 1, a method for automatically identifying a power supply of a solenoid valve includes the following steps:
1) detecting a power supply voltage value Vi1 when the power supply is lightly loaded to make a preliminary judgment to determine whether the power supply is a high-voltage power supply or a low-voltage power supply;
2) driving the electromagnetic valve to work to enable the power supply load to work, and detecting the power supply voltage value Vi2 again;
3) and comparing the difference value of the power supply voltage values Vi1 and Vi2 with a preset threshold value, and determining the specific type of the high-voltage power supply or the specific type of the low-voltage power supply by using the change conditions of the power supply voltage values before and after loading of different power supplies.
In the step 1), the preliminary judgment is that a threshold Vo is preset, then Vi1 is compared with the threshold Vo, if Vi1 is not less than Vo, the power supply is a low-voltage power supply, and otherwise, the power supply is a high-voltage power supply. In the present invention, Vo is a self-set power supply voltage boundary, such as 4.5V, but not limited thereto. The high-voltage power supply is a high-voltage power supply, and comprises a 5V adaptive power supply, a 4.5V power supply and the like, wherein the power supply voltage value of the high-voltage power supply is greater than Vo, and the 4.5V power supply can be a new series connection of 3 dry batteries or other types. The low-voltage power supply is a low-voltage power supply, and comprises 3.6V lithium sub-batteries or old 3 dry batteries connected in series, and the power supply voltage value of the low-voltage power supply is less than Vo.
In this step, if it is determined as a high-voltage power supply, a preset threshold V1 and V1 are reference constants for a preset solenoid valve closing to generate a power-down variation value for the power supply voltage, and are used to distinguish between a new dry battery series connection and an adaptive power supply, for example, V1 is 0.2V, but is not limited thereto. If the low-voltage power supply is determined, a threshold V2 for distinguishing the old dry battery series and the lithium sub-battery is preset, and V2 > V1, for example, V2 is 0.5V, but the invention is not limited thereto.
Further, the power supply is a light load when the power supply is not loaded, for example, when the electromagnetic valve is not used. When the electromagnetic valve is used, the power supply supplies power to the electromagnetic valve. In the step 2), the electromagnetic valve is driven and controlled to work, and the power supply load works according to the type of the electromagnetic valve, including when the electromagnetic valve is opened or closed, or at the moment of opening or closing.
The change conditions of the power supply voltage values before and after loading of different power supply sources are as follows:
first, according to kirchhoff's second law KVL, i.e., E ═ Ir + Ir, E is the electromotive force of the power supply, R is the internal resistance of the power supply, R is the external resistance, and I is the total current (main current). When the battery works under light load, the working current is small, the voltage occupied by the internal resistance of the battery is small, and the output voltage of the battery is large; when the battery works under load, the working current is large, the internal resistance of the battery occupies large voltage, and therefore the output voltage of the battery is small.
According to the relation between the battery voltage and the battery electric quantity, the battery output voltage reflects the battery electric quantity; when the electric quantity of the battery is reduced, the internal resistance of the battery is large, and the output voltage is small; when the electric quantity of the battery is large, the internal resistance of the battery is small, and the output voltage is large. The battery discharges with large current when being loaded, and the voltage of the battery with small electric quantity and capacity is reduced quickly and much; conversely, the battery with large capacity decreases slowly.
Referring to fig. 2a to 2c, in which fig. 2a is a 5V adaptive power supply, there is no voltage occupied by internal resistance of battery due to dc power supply, and the power supply voltage after loading has no change basically;
as shown in Δ V1 of fig. 2b, the fresh dry cell and the li-sub cell have large capacitance and small internal resistance, and the voltage change of the cell is small when the heavy load of Δ t time is applied;
Δ V2 as in FIG. 2 c; the old dry battery has small capacitance and large internal resistance, and the voltage change of the battery is large when the heavy load of delta t time is added.
Based on the above principle, the difference between the supply voltage values Vi1 and Vi2 is compared with a preset threshold value to determine the specific type of the power supply. The method comprises the following specific steps:
in step 3), for the specific type of the high-voltage power supply: and judging whether the difference between the supply voltage values Vi1 and Vi2 meets the condition that Vi1-Vi2 is more than or equal to V1, if so, the change of the supply voltage is explained, and the high-voltage supply power supply is formed by connecting new dry batteries in series, for example, 3 new dry batteries with 4.5V. If not, the voltage change of the power supply with sufficient power supply is small and can be ignored, and the high-voltage power supply is an adaptive power supply, such as a 5V adaptive power supply.
And when the new dry battery is judged to be connected in series, making a corresponding under-voltage prompt and executing corresponding dry battery under-voltage protection. And when the adaptive power supply is judged, controlling to execute corresponding adaptive power supply power-down protection.
Further, for a specific type of low voltage power supply: judging whether the difference value of the supply voltage values Vi1 and Vi2 meets the condition that Vi1-Vi2 is more than or equal to V2, if so, the change of the power supply voltage is large, the low-voltage power supply is formed by connecting old dry batteries in series, for example, 3 old dry batteries, the voltage is low, the internal resistance is large, and the supply voltage change before and after loading is large; if not, the change of the power supply voltage is small, and the low-voltage power supply is a battery with large capacity but low-voltage output, such as a 3.6V lithium sub-battery, which has low voltage and low internal resistance, and has small internal resistance even in the later discharge period and small change of the power supply voltage before and after the load.
When the old dry batteries are judged to be connected in series, corresponding under-voltage prompt is given and corresponding dry battery under-voltage protection is executed. And when the lithium sub-battery is judged, making a corresponding under-voltage prompt and executing corresponding under-voltage protection of the lithium sub-battery.

The power supply circuit 10 is further provided with a voltage conversion circuit, which is connected to the power supply to convert the voltage of the power supply, and the converted voltage supplies power to the main control board 40 and other module circuits. The power supply voltage value detected by the power supply detection circuit 20 is a voltage value before conversion.

The flush valve may include a solenoid valve 80 and a spray head 81, the spray head 81 being mounted to the water outlet end of the solenoid valve 80.
According to the flushing valve circuit and the urinal, after the power supply is installed, the power supply is connected to the main control board, and the working principle of identifying the type of the power supply is as follows:
when the power supply is powered on, firstly, the power supply voltage value Vi1 when the power supply is detected to be light by the power supply voltage detection circuit 20 is preliminarily judged, and whether the power supply is a high-voltage power supply or a low-voltage power supply is judged; then, the main control board 40 controls the electromagnetic valve driving circuit 30 to drive the electromagnetic valve 80 to be closed or opened, the electromagnetic valve serves as a power supply load, the power supply load works, the power supply voltage value Vi2 is detected again through the power supply voltage detection circuit 20, the main control board 40 compares the difference value between the power supply voltage values Vi1 and Vi2 with a preset threshold value, and the specific type of the high-voltage power supply or the specific type of the low-voltage power supply is determined by using the power supply voltage value change conditions before and after loading of different power supplies.
