The using method of checkout equipment of the present invention is:
Detection for " sensitivity and nerve " parameter: the warm-cold inleting pipe 5, rising pipe 6 and the flowing water joint 201 that connect tested water swivel 4, by the handle connection fixture 107 of tested water swivel 4, connect the handle 7 of tested water swivel 4, open hot and cold water pump 211, and move PLC301.By horizontal circumference stepper motor 106, driving tested water swivel 4 to do circular-rotation moves, drive tested water swivel 4 from complete cold position (ultra-Right), to start to rotate to hot water direction with the speed of 0.5 °/s, while arriving full thermal site (ultra-Left), with same speed, be back to complete cold position at once.
A, analog temperature detect: the hot and cold water data synchronous transmission that the data of horizontal circumference stepper motor 106 motions and hot and cold water flowmeter 212 are collected, to PLC301, converts signal to and is input in computer by signal picker 302.Computer expert crosses the unit rotational angle of collecting horizontal circumference stepper motor 106, and the faucet outlet temperature that synchronous collection calculates to the flow proportion of cold water and hot water forms following " rotational angle-water temperature " curve map, as shown in Figure 2 and Figure 3.
From cold water to hot water process, the water swivel angle position P01 when temperature reaches 34 ℃, the water swivel angle position P02 when temperature reaches 42 ℃, computer calculates angle value (sensitivity) G1=P02-P01 in this scope automatically; From hot water to cold water process; Water swivel angle position P11 when temperature reaches 42 ℃, the water swivel angle position P12 when temperature reaches 34 ℃, system is calculated angle value (sensitivity) G2=P11-P12 in this scope automatically.
