Description
Technical Field
The present disclosure relates to toilet maintenance. More particularly, the present disclosure relates to toilet management systems and methods employing IoT sensor devices.
Background
Sanitary products and equipment such as faucets, urinals, toilets, soap dispensers, hand dryers, toilet paper roll dispensers and other toilet products all work independently. These devices are typically not connected to any network and therefore do not provide any electronic feedback or status information to cleaning staff and technical staff servicing the toilet. The tasks of cleaning, diagnosing, inspecting, and replenishing dispensable items such as soap, toilet paper rolls, or paper towels are performed manually by cleaning staff. Also, technicians servicing the equipment must perform a walk through inspection or otherwise be reminded by cleaning staff to schedule the service. Since the consumption of consumables and the cleaning requirements are not precisely known, the maintenance of the toilet may be unpredictable, leading to inconsistent results and higher labor costs.
Whenever a malfunction or break occurs (e.g., water leak, faucet overflow, no flush), the technician typically does not realize until someone reports or complains of the problem. A technician is then deployed to identify and repair the malfunctioning plumbing fixture equipment. There is a need for a system or method with real-time information and predictive capabilities to better alert employees about any problems in the facility's toilet and immediately direct technical or cleaning staff to proceed with troubleshooting.

A Wi-Fi access point is a wireless access point that allows Wi-Fi devices to connect to a wired network. It is usually connected to the router as a stand-alone device (via a wired network), but it may also be an integral part of the router itself.
NB-IoT refers to a low power WAN standard that uses SIMs to implement cellular devices and services. NB-IoT is particularly focused on indoor coverage, low cost, long battery life, and high connection density. 3G is a widely used cellular telephone communication standard. NB-IoT or 3G may both provide coverage for remote areas without wired telecommunications infrastructure.
Message queue telemetry transport) is an ISO standard publish-subscribe based messaging protocol. It works on top of the TCP/IP protocol. It is designed for connection to remote locations that require small code footprint or limited network bandwidth.
The consumption status may be calculated based on sensor data of at least one of a soap dispenser sensor, a faucet sensor, a hand dryer power meter, a toilet paper roll dispenser sensor, a paper towel sensor, a waste bin sensor, at least one urinal flush sensor, and at least one toilet flush sensor. The environmental status may be calculated from sensor data of at least one of a temperature sensor, a humidity sensor, a sound level sensor, a smoke sensor, an odor sensor, a water leakage sensor, and an air quality sensor. The flow pattern may be calculated from sensor data of at least one of the RFID sensor, the person counter, the at least one urine flush sensor, and the at least one toilet flush sensor. The at least one odor sensor may be an ammonia sensor. Each emergency maintenance alert may be determined based on at least one of a consumption status, an environmental status, a traffic pattern, and a loss of communication between the server 12 and one of the IoT sensors.
The emergency maintenance alert may be categorized by at least one of a water leak, a faucet overrun, a flush failure, a soap dispenser refill indication, a paper towel refill indication, and a toilet paper refill indication. The flush failure may be due to, for example, insufficient water pressure, insufficient water flow, air in the water line, and/or excessive water pressure.
Machine learning or AI (sometimes referred to as machine intelligence) is the intelligence exhibited by machines, in contrast to the natural intelligence exhibited by humans and other animals. Machine learning or AI programs can mimic human functions associated with other human thoughts, such as learning and problem solving. The server 12 may use machine learning or AI to step up the quality of service ("QoS") for a particular cleaning task and predict future changes in the demand for consumables, maintenance, and repairs. For example, if the occupancy rate of a toilet 01 increases, the system 1-01 may predict that the toilet 01 will have an increased demand for soap, paper towels, and toilet paper rolls. For use in larger facilities, such as airports, machine learning or AI connections may also be used to connect additional data outside of the toilet management system, such as passengers that are about to arrive at the airport, to predict consumption and maintenance needs due to possible usage increases.
The report may include at least one of: (a) a consumption history comprising at least one of energy consumption, water consumption, paper towel consumption, trash bin usage, toilet paper roll consumption, and soap consumption, wherein the consumption history is calculated from sensor data in the time series profile; (b) a building management summary indicating a cleaning status and a maintenance status of the toilet 01; (c) a human management summary indicating at least one of availability of cleaning staff, availability of technical staff, a staff scheduling turn table, response time statistics, staff attendance statistics, staff efficiency statistics, and a plurality of staff replacement recommendations; (d) a performance index summary indicating at least one of an outage time metric, an equipment fault history, a cleanliness index, and a flow history; (e) system state including each IoT sensor and gateway 10; and (f) occupancy of each toilet 01 determined from sensor data collected from the urine flush sensor and the toilet flush sensor of each toilet 01. The entry in the equipment failure history record may include at least one of a unit identifier, a location, a frequency of failure, and a type of failure. The server 12 may be configured to recommend alternative toilets 01 to the user based on the occupancy of each toilet 01. Reports may be presented in at least one dashboard screen in each user interface 06.
Each user interface 06 may be configured to: (a) associating each task item with at least one member of the employee; (b) allowing the current task state of each task item to be updated; (c) recording readings of at least one motion sensor 05; and (d) recording the specific cleaning. Each user interface 06 may be at least one of a portable tablet, a smart phone, a dedicated device, a laptop computer, or a desktop computer. Each employee profile may include a work location, an employee ID, a work indication, and a work schedule.
