On the APP side, an anti-freezing reminding inlet can be arranged for each family (namely, for each group of outdoor units), and the opening/closing can be set by a family administrator.
The cloud platform may have pre-stored information as follows: the area (i.e., the home address) where each group of outdoor units is located, the device identification number of each wireless gateway device, and the open/close state (e.g., open or closed) of the anti-freezing point reminding entrance under each home.
Of course, the information may also include the home number ID, and the home administrator account.
The above information may be stored in a database of the cloud platform.
For example, two families (for example, one in the Qingdao and one in the Harbin) are set under the same APP account, and each family is provided with a group of outdoor units.
For example, a family in the Qingdao is provided with a group of outdoor units, and the group of outdoor units is provided with two outdoor units, namely: 11# outdoor unit and 12# outdoor unit.
The family of harbin sets up a set of outdoor unit, and this set of outdoor unit is provided with three outdoor unit, marks as: 21# outdoor unit, 22# outdoor unit and 23# outdoor unit.

And judging whether the wireless gateway equipment is offline, pulling the state of the wireless gateway equipment for multiple times through the cloud platform, and indicating that the wireless gateway equipment is offline when the feedback of the wireless gateway equipment is not received.
When monitoring the state of the wireless gateway device, attention needs to be paid to whether the wireless gateway device fails.
The wireless gateway device may fail in an online state, and when the failure occurs, the anti-freezing operation of the outdoor unit may be affected, so that the failure state of the wireless gateway device also needs to be monitored.
Reminder for outdoor unit
Referring to fig. 2, a process of reminding the multi-connected air-conditioning floor heating system is described in detail as follows.
S1: and the cloud platform updates the outdoor temperatures of different areas in the database at regular time.
The cloud platform receives the outdoor temperature on the third-party weather data platform and is used for updating the outdoor temperature of different areas in the database at regular time, for example, 1 time/day.
S2: and regularly inquiring the outdoor temperature of different areas in the database.
The database stores: and the anti-freezing reminding entries in different regions and the equipment identification numbers of at least one wireless gateway equipment in different regions.
The outdoor temperature corresponds to the area, the anti-freezing reminding inlet and the identification number of each device in the area.
S3, judging the outdoor temperature T in different areas Outer cover And if the temperature is less than or equal to the preset temperature T, the step S4 is carried out, and if not, the step S3 is carried out.
The preset temperature can be set to 0 ℃, and the value of the preset temperature can be configured through a WEB port opened by the cloud platform.
S4: judging the outdoor temperature T Outer cover All areas with the temperature less than or equal to the preset temperature TWhether each wireless gateway device is off-line or at an outdoor temperature T Outer cover And if the fault that the anti-freezing operation cannot be performed on each device in the multi-split air-conditioning floor heating system in all the regions with the temperature less than or equal to the preset temperature T occurs, if any one or both of the equipment are yes, the step is S5, and if not, the step is S7.
For example, the outdoor temperatures of the Qingdao area and the Harbin area in the database are both less than or equal to the preset temperature, and at this time, it is necessary to determine whether each wireless gateway device under at least one outdoor unit in the Qingdao area is offline and whether each wireless gateway device under at least one outdoor unit in the Harbin area is offline.
Specifically, the offline mode may be determined by actively pulling the state of the wireless gateway device by the cloud platform, repeating the state for multiple times, for example, after 5 times, no feedback exists, and considering that the wireless gateway device is offline.
For example, the 11# wireless gateway device in the 11# outdoor unit in the Qingdao area is offline, and the 21# wireless gateway device in the 21# outdoor unit in the Harrison area is offline.
For example, the outdoor temperatures of the Qingdao area and the Harbin area in the database are both less than or equal to the preset temperature, and at this time, it is necessary to determine whether a failure that the devices in the multi-split air-conditioning floor heating system in the Qingdao area cannot perform antifreeze operation exists or not and whether a failure that the devices in the multi-split air-conditioning floor heating system in the Harbin area cannot perform antifreeze operation exists or not.
The fault can be detected by a floor heating system of the multi-split air conditioner, and the fault can refer to abnormality of a sensor for detecting the temperature of a water supply pipeline, abnormality of a sensor for detecting the outdoor temperature, communication abnormality and the like.
When the fault occurs, the original anti-freezing operation protection can be stopped, and the outdoor unit pipeline is easy to freeze.
Therefore, when a fault occurs, a user needs to be reminded to repair the unit in time or drain the water in the unit in time. S5: and judging whether the anti-freezing reminding entrance in the area is opened or not, if so, going to S6, and if not, not performing anti-freezing reminding.
At the APP side, a freeze-proof reminding inlet is arranged under different regions for a group of outdoor units.
For example, an 11# anti-freezing reminding inlet is arranged under the Qingdao area, and a 21# anti-freezing reminding inlet is arranged under the Harbin area.
And when the 11# wireless gateway equipment is offline, judging whether the 11# anti-freezing reminding inlet under the corresponding Qingdao area is opened or not.
When the 21# wireless gateway equipment is offline, whether the 21# anti-freezing reminding inlet in the corresponding Harbin region is opened or not is judged.
When the equipment in the multi-split air-conditioning floor heating system under the Qingdao area has the fault that the anti-freezing operation cannot be carried out, judging whether the corresponding No. 11 anti-freezing reminding inlet under the Qingdao area is opened or not.
When the equipment in the multi-split air-conditioning floor heating system under the Harbin region has a fault that the anti-freezing operation cannot be performed, whether the corresponding 21# anti-freezing reminding inlet under the Harbin region is opened or not is judged. S6: and sending reminding information to the APP, and then returning to S3.
And sending reminding information to the APP to remind the user to carry out corresponding protective measures, such as recovering the power supply of the outdoor unit.
The content of the reminding message can be: user just your! In order to avoid frost cracking damage of your unit when outdoor temperature is low, do not cut off the unit power. If normal supply of electric power cannot be guaranteed, water in the unit must be emptied to prevent the unit from freezing.
Alternatively, when the phone number of the home administrator is stored on the cloud platform, the cloud platform may push the short message information to the phone number of the administrator, and the content of the short message information may be as described above.
Alternatively, at least the mobile phone number of the administrator (and the opening and closing states of the area and the anti-freezing reminding entrance) can be sent to the after-sales service platform, and when the condition that the APP sends the reminding information is met, the after-sales service platform initiates phone reminding.
The after-market platform may notify 400 the return visit/auto-dial user to make a phone call alert for emergency purposes.
S7: and (6) ending.
In S7, the outdoor unit performs the normal protection of the existing freezing operation, such as the protection of the water circuit.
By adopting the reminding mode, when the outdoor temperature is lower than the preset temperature, namely, the outdoor state is represented, whether the outdoor unit has power supply abnormity is judged by judging whether the corresponding wireless gateway equipment is off-line, and when the wireless gateway equipment is off-line, the reminding information is sent through the anti-freezing reminding inlet opened at the APP side to remind a user of timely adopting protective measures for the outdoor unit.
When the outdoor temperature is lower than the preset temperature, the wireless gateway equipment is judged off line, and the pressure of the server is reduced.
And when the outdoor of a certain area is in a low-temperature state and equipment in the multi-split air-conditioning floor heating system under the area has a fault that the anti-freezing operation cannot be performed, the anti-freezing reminding inlet opened on the APP side is used for sending reminding information to remind a user of taking protective measures for an outdoor unit group in time. To optimize the platform process, the above-described reminders may be implemented only for defined seasons and/or regions, e.g., during months other than 6, 7, 8, 9 months of the year, not in the Hainan region, etc.
