Base station, cleaning system, and method for self-checking thereof
The present disclosure provides a base station for a mobile cleaner. The base station includes a dock, a cleaning unit, a water assembly, and a self-checking module. The dock is configured to accommodate the mobile cleaner. The cleaning unit is configured to clean the mobile cleaner accommodated in the dock. The water supply assembly is configured to supply water to the cleaning unit from a water source. The self-checking module is configured to detect a malfunction regarding conveyance of water from the water source to the cleaning unit.
1. A base station for a mobile cleaner, comprising: a dock configured to accommodate the mobile cleaner; a cleaning unit configured to clean the mobile cleaner accommodated in the dock; a water supply assembly configured to supply water to the cleaning unit from a water source, wherein the water supply assembly comprises: an inlet connected to the water source, an outlet connected to the cleaning unit, and a water tank configured to accumulate water conveyed from the water source through the inlet and to supply water to the cleaning unit through the outlet; and a self-checking module configured to detect a malfunction regarding conveyance of water from the water source to the cleaning unit, wherein the self-checking module comprises: a memory configured to store a computer program; a processor configured to execute the computer program to perform functions of the self-checking module; a first water level detector configured to detect an amount of water accumulated in the water tank, and to generate a complete signal in response to the amount of water accumulated in the water tank reaching a first water level, wherein when the complete signal is received from the first water level detector before expiration of a first preset period, the self-checking module is configured to generate, by the processor, a type-I warning signal; when the complete signal is not received from the first level detector after a second preset period has passed, the self-checking module is configured to generate, by the processor, a type-II warning signal; and wherein the second preset period is equal to or longer than the first preset period.
2. The base station of claim 1 , further comprising a valve positioned between the inlet and the water source, wherein the self-checking module comprises a controller electrically coupled to the valve and configured to control the valve, and wherein the self-checking module is configured to detect a correct working state of the valve, and generate, by the processor, a type-III warning signal when the valve is not in the correct working state.
3. The base station of claim 1 , wherein the self-checking module comprises a first flow meter configured to detect an inlet velocity of the water conveyed into the water tank through the inlet, and wherein the self-checking module is configured to compare, by the processor, the detected inlet velocity with a default inlet velocity, and generate, by the processor, a type-IV warning signal when the detected inlet velocity deviates from the default inlet velocity beyond a first margin.
4. The base station of claim 1 , wherein the self-checking module comprises a second water level detector configured to detect an amount of water accumulated in the water tank,
wherein the second water level detector generates an overflow signal in response to the amount of water accumulated in the water tank reaching a second water level, and the second water level is equal to or higher than the first water level; and
wherein, when the overflow signal is received from the second water level detector, the self-checking module is configured to generate, by the processor, a fifth warning signal.
5. The base station of claim 4 , wherein, when the overflow signal is not received from the second level detector after a third preset period has passed, the self-checking module is configured to generate, by the processor, an eighth warning signal, and the third preset period is equal to or longer than the second preset period.
6. The base station of claim 1 , wherein the self-checking module comprises an anti-overflow detector configured to generate a spill-over signal in response to the water overflowing from the water tank, and
wherein, when the spill-over signal is received, the self-checking module is configured to generate, by the processor, a sixth warning signal.
7. The base station of claim 1 , wherein the self-checking module comprises a second flow meter configured to detect an outlet velocity of the water conveyed out of the water tank through the outlet, and
wherein the self-checking module is configured to compare, by the processor, the detected outlet velocity with a default outlet velocity, and generate, by the processor, a seventh warning signal in response to the detected outlet velocity deviating from the default outlet velocity beyond a second margin.
8. The base station of claim 1 , wherein a user of the mobile cleaner is notified of at least one of the type-I and type-II warning signals, and wherein the notification is in at least one of the following forms: displaying on a screen of the mobile cleaner, displaying on a screen of the base station, emitting an acoustic signal from the mobile cleaner audible by the user, emitting an optic signal from the mobile cleaner viewable by the user, emitting an acoustic signal from the base station audible by the user, emitting an optic signal from the base station viewable by the user, transmitting a wireless signal from the mobile cleaner to a terminal device of the user, or transmitting a wireless signal from the base station to the terminal device of the user.
