Self-checkout terminal sleep and wake operations
Disclosed are self-checkout terminals and systems and methods for controlling the same. The systems and methods may include receiving a first image of the customer queuing area from the first camera and determining that a customer is in the customer queuing area. A first wakeup signal may be transmitted to one of the self-checkout terminals when the customer is in the customer queuing area. A second image of the customer queuing area may be received from the first camera and a determination may be made that the customer queuing area is void of customers. A first sleep signal may be transmitted to the one of the self-checkout terminals when the customer queuing area is void of the customers.
1. A method comprising:
receiving, at a computing device from a camera, an image of a customer queuing area;
determining, by the computing device, that a customer is in the customer queuing area based upon the image containing the customer in the customer queuing area;
determining one of a plurality of self-checkout terminals the customer is approaching based on multiple frames of the customer in the customer queuing area;
transmitting, by the computing device, a first wakeup signal to the one of the plurality of self-checkout terminals when the customer is in the customer queuing area; and
waking the one of the plurality of self-checkout terminals in response to transmitting the first wake up signal,
wherein the first wakeup signal includes an indication of an awake stage from a plurality of awake stages, each of the plurality of awake stages corresponding to a different power consumption level, and
wherein waking the one of the plurality of self-checkout terminals includes waking the one of the plurality of self-checkout terminals to the awake stage.
2. The method of claim 1 , wherein transmitting the first wakeup signal to the one of the self-checkout terminals includes transmitting the first wakeup signal to a self-checkout terminal closest to the customer.
3. The method of claim 1 , further comprising transmitting a second wakeup signal to a second one of the plurality of self-checkout terminals.
4. The method of claim 1 , further comprising transmitting a first sleep signal to the one of the plurality of self-checkout terminals.
5. The method of claim 1 , wherein determining that a customer is in the customer queuing area includes determining a proximity of the customer to the one of the plurality of self-checkout terminals.
6. A method comprising:
receiving, at a computing device from a camera, an image of a customer queuing area;
determining, by the computing device, that the customer queuing area is void of customers based upon the image being void of the customers in the customer queuing area;
determining one of a plurality of self-checkout terminals the customer is approaching based on multiple frames of the customer in the customer queuing area;
transmitting, by the computing device, a first sleep signal to the one of the plurality of self-checkout terminals when the customer queuing area is void of the customers; and
putting to sleep the one of the plurality of self-checkout terminals in response to transmitting the first sleep signal,
wherein the first sleep signal includes an indication of a sleep stage from a plurality of sleep stages, each of the plurality of awake stages corresponding to a different power consumption level, and
wherein putting to sleep the one of the plurality of self-checkout terminals includes power down the one of the plurality of self-checkout terminals to the sleep stage.
7. The method of claim 6 , wherein transmitting the first sleep signal to the one of the self-checkout terminals includes transmitting the first sleep signal to a self-checkout terminal furthest from the customer queuing area.
8. The method of claim 6 , further comprising transmitting a second sleep signal to a second one of the plurality of self-checkout terminals.
9. The method of claim 6 , further comprising transmitting a first wake signal to the one of the plurality of self-checkout terminals.
10. A system for controlling a plurality of self-checkout terminals, the system comprising:
a first camera arranged to capture images of a customer queuing area;
a processor; and
a memory that stores instructions that, when executed by the processor, cause the processor to perform actions comprising:
receiving a first image of the customer queuing area from the first camera,
determining that a customer is in the customer queuing area based upon the image containing the customer in the customer queuing area,
determining one of the plurality of self-checkout terminals the customer is approaching based on multiple frames of the customer in the customer queuing area,
transmitting a first wakeup signal to the one of the plurality of self-checkout terminals when the customer is in the customer queuing area,
receiving a second image of the customer queuing area from the first camera,
determining that the customer queuing area is void of customers, and
transmitting a first sleep signal to the one of the plurality of self-checkout terminals when the customer queuing area is void of the customers,
wherein the first wakeup signal includes an indication of an awake stage from a plurality of awake stages, each of the plurality of awake stages corresponding to a different power consumption level, and
wherein the first sleep signal includes an indication of a sleep stage from a plurality of sleep stages.
11. The system of claim 10 , further comprising the plurality of self-checkout terminals, wherein each of the plurality of self-checkout terminals is configured to wake or sleep in response to receiving the first wakeup signal or the first sleep signal.
12. The system of claim 10 , further comprising a plurality of cameras, the first camera being one of the plurality of cameras, each of the other plurality of cameras arranged to capture images of a respective one of the plurality of self-checkout terminals.
13. The system of claim 10 , wherein transmitting the first wakeup signal to the one of the self-checkout terminals includes transmitting the first wakeup signal to a self-checkout terminal closest to the customer.
14. The system of claim 10 , further comprising transmitting a second wakeup signal to a second one of the plurality of self-checkout terminals.
15. The system of claim 10 , wherein determining that the customer is in the customer queuing area includes determining a proximity of the customer to the one of the plurality of self-checkout terminals.
16. The system of claim 10 , wherein transmitting the first sleep signal to the one of the self-checkout terminals includes transmitting the first sleep signal to a self-checkout terminal furthest from the customer queuing area.
17. The system of claim 10 , further comprising transmitting a second sleep signal to a second one of the plurality of self-checkout terminals.
