Please select the most similar patent number from A, B, C and D. Which number is?
Provided are a bathroom safety control system and an air conditioner. The air conditioner comprises: an acquisition module, which is used for acquiring information of a user entering and exiting a bathroom, and a water consumption volume; a storage module, which is used for storing a water consumption volume threshold value corresponding to a normal bathroom activity of the user, and/or a historical water consumption volume-time curve corresponding to a plurality of normal bathroom activities of the user or a preset historical water consumption volume-time curve normal fluctuation range; and a control module, which is used for generating a water consumption volume-time curve according to the water consumption volume and the corresponding time, and outputting alarm information when the water consumption volume exceeds the water consumption volume threshold value corresponding to the normal bathroom activity of the user and/or when the water consumption volume-time curve does not meet the historical water consumption volume-time curve or the preset historical water consumption volume-time curve normal fluctuation range. Therefore, by means of the present invention, a water consumption situation of a user in a bathroom is acquired by means of the air conditioner, whether the user has had an accident is determined according to the water consumption situation, and an alarm is given when an accident occurs.
A: A water usage pattern-based user profiling method and system, comprising the following steps: (1) collecting water usage data and a user type label of a user; (2) extracting from the collected water usage data the average water usage of several periods to serve as eigenvectors, combining with the type label of the user to construct a training sample set, constructing a depth-stratified fuzzy system on the basis of an automatic machine learning technique, utilizing the training sample set to train the system, thus constructing a classification model; and (3) inputting the collected water usage data of the user into the constructed classification model, thus completing user profiling. The method, by means of user profiling, combines characteristics of individual users and user groups, thus providing individual users with a service of increased accuracy, and implementing a reasonable allocation of resources between areas.
B: An air conditioner intelligent control method and device and an air conditioner. The method is used for controlling air conditioners in other rooms outside a bathroom, and the method comprises: receiving a user instruction; starting a water heater in a bathroom in a linkage mode according to the user instruction; when the water heater reaches set parameters, issuing a reminder; monitoring a bathing state of a user in the bathroom; and controlling the air conditioner to operate according to the bathing state of the user. According to the air conditioner intelligent control method and device and the air conditioner, the air conditioner and the water heater are controlled in the linkage mode to form an intelligent home control method for bathing of a user, the water heater can be started by means of the air conditioner, and a reminding function is additionally set; in addition, the air conditioner is controlled to operate according to the bathing state of the user, the temperature in a room can be regulated and controlled by means of the air conditioner when the user takes a bath, and the user is prevented from feeling a large temperature difference when walking into the room after taking the bath, thereby reducing the risk of catching a cold, and improving the comfort level.
C: Provided is a method for controlling a water heater, said method for controlling a water heater comprising the following steps: obtaining a first water consumption parameter corresponding to a user within a first time period, said first water consumption parameter comprising a first water consumption amount and a first water temperature, said first water consumption amount being determined according to water reliability; according to the first water parameter and the heating power of the water heater, determining a target advance heating time corresponding to the first time period of the water heater; according to the target advance heating time, controlling the operation of the heating device of the water heater.
D: A sewage pipe network real-time simulation method based on water supply Internet of Things data drive. The method involves an offline module and a real-time online module, wherein the offline module integrates a sewage pipe network model and a water supply pipe network hydraulic model, corrects historical water consumption of each node of the water supply pipe network hydraulic model, establishes a correction single-objective optimization model of the sewage pipe network model, and determines a transfer coefficient between the water consumption of each node and an inflow of an inspection well; and the real-time online module realizes the real-time simulation of hydraulic parameters of the sewage pipe network model. The method fills a vacancy in the field of sewage pipe network real-time simulation, and is an important supplement to the field of urban drainage pipe network management research; and important technical support is provided for the management of sewage pipe network systems, and the method has good value in promotion and practical engineering application.
