Abstract

The invention relates to an output signal detection circuit and a detection method of a dish-washing machine flowmeter, wherein the detection circuit comprises a singlechip, a detection circuit and a flowmeter, the detection circuit receives the output signal of the flowmeter, the signal is processed by the detection circuit and is then transferred to the singlechip, and the singlechip validates the input signal through the detection method. The detection method comprises a low level validation phase, a high level validation phase and a pulse validation phase. The invention has the beneficial effects that: the universal singlechip resources can be utilized, the pulse is identified and processed through the logical judge of the software algorithm, so the purposes of reducing the development cost and improving the water inflow accuracy of the dish-washing machine flowmeter are realized, the hardware is simpler and is easy to maintain, and the software design algorithm is easy to transplant.

Description

technical field

[0001] The invention belongs to the field of dishwasher water inlet precision detection, in particular to a detection circuit and a detection method for output signals of a dishwasher flowmeter, and belongs to an improvement technology for the output signal detection circuit and detection method of a dishwasher flowmeter. Background technique

[0002] Dishwashers have different washing stages in the process of washing tableware. Each washing stage requires a certain amount of water, and water consumption is an important parameter of dishwasher products. The accuracy and reliability of each water intake directly affects to the performance and energy consumption of dishwasher products.

[0003] At present, the dishwasher in the prior art usually uses a flowmeter to measure the water intake. During the water intake process, this water intake device can convert the water volume into a certain number of on-off interval cycles. After processing by the conversion ci...
