Abstract
The utility model relates to the field of information technology and especially to a shopping cart alarm based on a wifi network. The shopping cart alarm comprises a shopping cart, a wifi connection terminal, a wifi local area network connector, a wifi connection monitor. The wifi local area network connector is connected with wifi connection monitor in a wireless or wired manner. The wifi connection terminal is installed on the shopping cart. One or more wifi local area network connectors are fixed to a supermarket building or parking lot building. The shopping cart alarm based on a wifi network utilizes wifi network technology and gives an alarm if a terminal is outside the range of wifi network coverage so as to effectively decrease shopping cart losing cases.
Description
Technical field
The utility model relates to areas of information technology, relates in particular to a kind of shopping cart alarm based on wifi network.
Background technology
Present part supermarket, in order better to serve, to make things convenient for customers, can allow client that shopping cart is released to parking lot outdoors, supermarket, makes things convenient for customers goods is pushed and is discharged on car; Yet supermarket, for such service is provided, needs to drop into larger manpower and comes monitoring management shopping cart to avoid shopping cart stolen; Though more existing supermarkets are used wireless induction technology and supervised shopping cart, as infrared induction technology, because its distance of reaction is short, be difficult to cover parking lot, supermarket scope, thereby the more difficult client of meeting shifts shopping cart onto parking lot position.For overcoming the above problems, the utility model has designed a kind of shopping cart alarm based on wifi network, has used wifi induction technology, can cover preferably larger parking lot scope, and when exceeding certain limit, report to the police, can effectively reduce like this situation that shopping cart is lost.
Summary of the invention
Technical problem to be solved in the utility model is: the problem that shopping cart is stolen, existing wireless induction technology distance of reaction is short.
For solving the technical scheme that its technical matters the utility model adopts, be: a kind of shopping cart alarm based on wifi network, comprise: shopping cart 1, wifi connect terminal 2, wifi local area network connector 3, wifi connection monitoring device 4, wifi connects terminal 2 and is arranged on shopping cart 1, and one or more wifi local area network connectors 3 are fixed on supermarket building thing or parking lot buildings;
It is characterized in that: wifi connects in terminal 2 and comprises wireless signal transceiver 5, network connecting circuit 6, network analysis circuit 7, alarm 8, wireless signal transceiver 5, network connecting circuit 6, network analysis circuit 7 is connected successively with alarm 8, wireless signal transceiver 5 connects by network connecting circuit 6 and wifi local area network connector 3 after the wireless signal that receives wifi local area network connector 3, connection signal in network connecting circuit 6 is input to network analysis circuit 7, network analysis circuit 7 is controlled alarm 8 according to its analytic signal, when having the wifi of appointment network to connect, alarm 8 is in closed condition, when connecting without wifi network or connect without the wifi network of appointment, alarm 8 sends alarm sound, wifi local area network connector 3 can be set up wireless or wired connection with wifi connection monitoring device 4, wifi connection monitoring device 4 can monitor that each wifi of wifi local area network connector 3 connects the connection status of terminal 2.
Principle of work: wifi connects terminal 2 and is arranged on shopping cart 1, and wifi connects terminal 2 by search wifi signal, and judges wifi signal source ID; If the ID that its signal source is appointment, is also wifi local area network connector 3 in supermarket and sends signal, wifi connects terminal 2 and connects its LAN, and now alarm 8 is in closed condition; If without specifying ID or there is no wifi signal, also exceed the wireless signal scope of wifi local area network connector 3 in supermarket, wifi connects terminal 2 in without network connection state, and now alarm 8 is in open mode, and sends alarm sound.
Accompanying drawing explanation
Fig. 1 is that this practical wifi connects terminal theory structure schematic diagram;
Fig. 2 is the utility model schematic diagram;
In figure: 1 be shopping cart, 2 for wifi connect terminal, 3 for wifi local area network connector, 4 for wifi connection monitoring device, 5 for wireless signal transceiver, 6 for network connecting circuit, 7 for network analysis circuit, 8 be alarm.
Embodiment
With reference to accompanying drawing, further illustrate and realize embodiment of the present utility model (as shown in Figure 1, Figure 2):
Scheme one: a kind of shopping cart alarm based on wifi network, comprise: shopping cart 1, wifi connects terminal 2, wifi local area network connector 3, wifi connection monitoring device 4, wifi connects in terminal 2 and comprises wireless signal transceiver 5, network connecting circuit 6, network analysis circuit 7, alarm 8, wireless signal transceiver 5, network connecting circuit 6, network analysis circuit 7 is connected successively with alarm 8, wireless signal transceiver 5 connects by network connecting circuit 6 and wifi local area network connector 3 after the wireless signal that receives wifi local area network connector 3, connection signal in network connecting circuit 6 is input to network analysis circuit 7, network analysis circuit 7 is controlled alarm 8 according to its analytic signal, wifi local area network connector 3 is set up wired connection with wifi connection monitoring device 4, wifi connection monitoring device 4 can monitor the connection status of each connection terminal of wifi local area network connector 3, wifi connects terminal 2 and is arranged on shopping cart 1, wifi local area network connector 3 is fixed on supermarket building thing.
Further illustrate, during enforcement, above-mentioned wifi local area network connector 3 can be with common wireless router, and monitor 4 can be used common computer.
Scheme two: be with scheme one difference: the wireless connections that are connected to of wifi local area network connector 3 and wifi connection monitoring device 4, a plurality of wifi local area network connectors 3 are fixed on supermarket and parking lot buildings, and wifi connects the terminal 2 the strongest wifi local area network connector 3 of signal that can certainly be dynamically connected.
