1. Every time the power is on, the functions of the whole set of system are self-checked, if the equipment is successfully initialized without abnormal voice prompt, the intelligent water drinking equipment in the rich source of the century is welcomed to be used. At the moment, the power indicator lamp on the main control board is turned on, the working state indicator lamp flickers (when the communication with the display screen is normal), the power indicator lamp of the drive board is normally turned on, and the working state indicator lamp flickers (when the communication with the main control board is normal).

2. A water preparation part: after the self-checking of the first electrifying equipment is completed, after a source water level (controlled by a hydraulic switch and a display screen water shortage icon is lightened during disconnection) switch is switched on, a power supply of a water purifier is switched on (a DC24V switching signal) and the water purifier starts to work (a corresponding work indicator lamp on a drive plate is lightened) until the water purifier is switched off to a full water level (controlled by the hydraulic switch and the display screen water full icon is lightened after the water purifier is switched off), all working states of a water making part are stopped, and when the full water level is switched on again, the water making state is delayed for 30 seconds and then the water making part normally works (the circulation. The source water level switch is continuously switched off for 10 minutes, then the voice of the lack of water of the source water is prompted (the fault code E7 can be automatically recovered after being switched on) is sent to the server side, under the normal water production state, the water production is stopped after the source water level is continuously switched off for 10 seconds, and the water production fault is prompted after the low water level is continuously switched off for 15 minutes (the fault code E12 voice prompts the water production fault to be checked, and the low water level can be automatically recovered when being switched on again without power failure and restart), but other functions are not influenced; when the continuous water production time exceeds 3 hours, water production is suspended no matter what state the water level is in, and normal operation is continued after 10 minutes (the original E11 fault is cancelled).

3. Heating part: after the self-checking of the electrified equipment is finished for the first time, the heating liner starts water inflow while water making work is carried out, when the water level reaches the water level of the heating liner (controlled by a mechanical float switch) and is switched on, the heat preservation heating is started (2 groups of heating relays start the heat preservation icon to roll) and the heating is stopped (the heat preservation icon is static) when the upper limit of the set heat preservation temperature is reached, the heat preservation heating is started again (the circulation is carried out, the switching and starting are carried out among 3 groups of relays when the heat preservation heating is started every time) when the heat preservation temperature reaches the lower limit of the set heat preservation temperature, the upper limit and the lower limit of the heat preservation temperature can be adjusted on the display screen (the adjusting range is 0-97 default upper limit is 85 degrees, the lower limit is 80 degrees, the heat preservation temperature is detected by a heat preservation temperature sensor), when a boiling water key is switched on, 3 groups of heating (the, the heating temperature is detected by a heat temperature sensor), the heating is switched to intermittent heating (the starting time and the stopping time of the intermittent heating can be adjusted by a display screen, the adjusting range is 1-20 seconds, the default starting time is 10 seconds and the stopping time is 5 seconds), and the heating is stopped (the heating icon is static) when the boiling water key is disconnected, so that the heating enters a heat preservation working state. The upper and lower limits of the heat preservation temperature and the boiling water temperature cannot conflict, whether each working state and working are normal or not needs to be reflected at the server end, whether the heating part is normal or not is detected by the three-phase current transformer, if abnormal heating is detected, voice prompt 'abnormal heating, no use is needed' (the abnormal heating is prompted only when the boiling water key is switched on, if the boiling water key is not switched off for a long time, the boiling water key is continuously switched on for 3 minutes at intervals for 2 minutes and then is automatically switched off), and meanwhile, the heating water cannot be taken at the server end (the server end needs to prompt in real time and is not influenced by the boiling water key). The prompt and normal water use may not be cancelled until the fault is restored.

4. A refrigerating part: after the self-checking of the first-time power-on equipment is completed, the compressor is started to refrigerate (corresponding compressor working indicator lamps on a drive plate are turned on simultaneously, a display screen refrigeration icon rolls) according to refrigeration temperature setting (refrigeration temperature is set to be adjustable through a display screen and is divided into starting temperature and stopping temperature, the set range is 10-25 ℃, the default starting temperature is 23 and stopping temperature is 18), the compressor is started to refrigerate (corresponding compressor working indicator lamps on the drive plate are turned off simultaneously, the display screen refrigeration icon is static), and when the temperature rises to the starting temperature again, the compressor is started to refrigerate (the circulation is performed), and the refrigeration is started again, so that a limitation exists: the starting time and the last stopping time are separated by more than 3 minutes before starting. If the compressor continuously works for more than 1 hour, the compressor is not stopped, refrigeration is required to be stopped regardless of the temperature, and the voice prompt that the refrigeration is abnormal and the maintenance is required in time (the prompt prompts the compressor once every 2 minutes until the compressor can be recovered after power-off and restart) is carried out, the working state and the working state are normally reflected in real time at the server end.

A water taking part: in the networked charging mode, various water can be discharged only after receiving a corresponding instruction of WeChat payment (the non-networked mode does not need to receive the instruction), when a sound prompt of a buzzer for dropping water is received, corresponding button light flickers and a voice prompt of scanning success is carried out, a user can operate after touching a key to take water and a drinking icon is lightened (the drinking icon is controlled by a lower limit value of the water temperature, the lower limit value is lightened when the drinking icon is reached, the lower limit value is lower than the lower limit value, the lower limit value of the water temperature is 0-85 adjustable, and the scanning key is defaulted to be 82 ℃), and when the water boiling key is switched on, the user can not scan the key again to discharge water until the water temperature is heated to be reached. When the water temperature is in the range of water outlet, a water boiling button is switched on, the water boiling solenoid valve is firstly prompted by voice to use the boiled water and scald carefully (the icon of the water boiling valve on the display screen is lightened), the water boiling solenoid valve is switched on to discharge water after the voice prompt is finished, when the water temperature is not enough in the process of taking the boiled water, the water boiling button is switched off and the water boiling solenoid valve stops discharging water, but the heating cannot stop (the water boiling button is switched off to be in a heat preservation state) until the water is heated to the upper limit value of the heat preservation temperature, the warm water and the ice water are not subjected to temperature control, water can be discharged as long as a water taking instruction is received in a networking mode, the display screen is lightened corresponding to the icon of the water outlet valve when the water outlet valve is opened, the current accumulated flow and flow rate are displayed on the display screen when the water is taken, the current flow rate is uploaded to a microcomputer end in real, but the total water intake amount of each time needs to be added up to the total water consumption. And if the water getting instruction is received for 10 seconds, the current water getting instruction is automatically cancelled if no flow signal is detected. When the water outlet electromagnetic valve is damaged and water can not be discharged in a normal water taking state, the flow meter needs to report the fault of the corresponding water outlet electromagnetic valve when the flow meter can not detect a water flow signal, and the fault is interconnected with the server side, and the fault cannot be detected when the low water level is not connected. In any mode, the water is automatically cut off after a single faucet continuously discharges water for 3 minutes, and the water is automatically cut off when the water taking balance is detected to be insufficient.
