firstly, storing the signal value acquired in the standby state after the urine analyzer is started, namely the stored value,

then the signals of the urine analyzer are collected in real time and compared with the stored values,

when setting the storage value and the storage value range, according to the urine analyzer, the alternating current voltage is 220V, the current is zero when the urine analyzer is shut down,

after the machine is started, the standby current is 0.20A, the working current value is 0.33-0.38A, and the current value is reduced to the standby level after the working is finished.

Therefore, the current value is increased by more than 60 percent when in work compared with the current value when in standby, the alternating current voltage is set to be +10 percent to-20 percent (the regulated allowable fluctuation range of the national grid voltage is +/-10 percent) in consideration of the influence of the change of the alternating current voltage on the current value,

Therefore, the change of the network voltage can bring the change within 10 percent of the current value,

therefore, a change in the current value exceeding 10% or more should be caused by a change in the state of the device.

For the sake of safety, in the embodiment, when the set storage value and the range thereof are collected, it is considered that the state is the on state or the working state when the storage value is greater than 40% of the standby current, and the state is considered that the state is the off state when the storage value is lower than 40% of the standby current.
