FIELD

The device and method disclosed in this document relates to occupancy sensing and, more particularly, to an occupancy sensing system for custodial services management.

BACKGROUND

Unless otherwise indicated herein, the materials described in this section are not prior art to the claims in this application and are not admitted to the prior art by inclusion in this section.

Custodial service provides the cleaning services in buildings. It is expensive and has a multi-million-dollar market in airports, hospitals, stadiums, theaters, academic buildings, and convention centers. Current custodial services are typically based on static schedules and do not monitor or take into account the number of people using the facility in real-time. Accordingly, some restrooms which are heavily used may be under-serviced by custodial staff and restrooms are only rarely used may be over-serviced by custodial staff, leading to inefficient workforce management and increased costs.

SUMMARY

An occupancy sensing system is disclosed. The occupancy sensing system comprises: a plurality of occupancy sensors, each occupancy sensor being installed at an entryway to a respective site of a plurality of sites, each occupancy sensor having a depth sensor that faces the entryway to the respective site and is configured to provide depth sensor data, each occupancy sensor being configured to (i) determine a flow of people through the entryway to the respective site based on the depth sensor data and (ii) determine a number of people occupying the respective site at a plurality of different times based on the determined flow of people through the entryway to the respective site; and a server communicatively coupled to the plurality of occupancy sensors and configured to receive data from the plurality of occupancy sensors indicating the number of people occupying each of the plurality of sites at the plurality of different times.
