Heat source body is detected inside fruit locker, then representing has child or animal to be strayed into locker, server to apart from locker most
Nearly administrator or customer service send a warning message, and illustratively, warning information includes locker position, bin position, warning edge
By, wherein warning cause may include child or the time that animal is strayed into.Alarm is sent to administrator or customer service in server
After information, server can also control locker and issue sound flash alarm system, ask for help to the neighbouring masses, can also be in display screen
On show child or animal is strayed into the information of locker.Administrator or customer service can rapid organizers after receiving warning information
Member opens the locker bin and is rescued.
If server, which does not detect, to be had inside locker similar in human body or the IR wavelength distributed with human body
Whether animal dis exists, then server starts distance measuring sensor, detect with the presence of package inside locker, if it is present ranging
Sensor detects the size of the package, and server adds up the deposit time for being wrapped in locker, if this is wrapped in
The deposit time of locker is more than preset time threshold, illustratively, when preset time threshold can be the storing of user
It is long, or to increase a period of time on the basis of storing duration, or regular time, server to administrator or
Person's customer service sends work order process and administrator or customer service is notified to handle according to rules and regulations, and illustratively, work order process includes
Locker position, bin position, storing duration, deposit time and package size.If this is wrapped in the deposit time of locker
It is not above preset time threshold, then according to storing duration normal storage.If existed in locker without package, service
Device sends the prompting message of the locker bin without package to administrator, and administrator can be handled according to rules and regulations.
Alternative, server is detecting the IR wavelength for having human body inside locker bin or distributing with human body
In the presence of similar animal, locker can be directly controlled and open the bin, child or animal is prevented to be strayed into, and in a period of time
More than after preset frequency threshold value, server can send to administrator or customer service and remind letter the number of repetition of this interior operation
Breath, administrator or customer service can arrange personnel on site to check.
The technical solution of the present embodiment, server by when detect the cabinet door close when, detect locker in whether
There is heat source body；If having heat source body in detection locker, send a warning message to administrator；If detected in locker without heat
Whether source body then detects in locker with the presence of package；When the locker is there are when the package, posting for the package is judged
Deposit whether the time is more than preset time threshold；It is detained package information if it does, then sending to administrator, solves deposit bin
It is easy to happen child/toy and is strayed into the problem of either package is detained, realize that detection child or animal are strayed into express delivery in time
Cabinet and alarm reduce the effect of personal risk.
Note that the above is only a better embodiment of the present invention and the applied technical principle.It will be appreciated by those skilled in the art that
The invention is not limited to the specific embodiments described herein, be able to carry out for a person skilled in the art it is various it is apparent variation,
It readjusts and substitutes without departing from protection scope of the present invention.Therefore, although being carried out by above embodiments to the present invention
It is described in further detail, but the present invention is not limited to the above embodiments only, without departing from the inventive concept, also
It may include more other equivalent embodiments, and the scope of the invention is determined by the scope of the appended claims.
