Abstract
The utility model relates to a circuit device and particularly relates to an anti-lost device. The anti-lost device comprises a pressure sensing device I a pressure sensing device II which are respectively in electrical signal connection with an information processing device, wherein the information processing device is in electrical signal connection with an alarm device; the pressure sensing device I is internally provided with a smart switch and is arranged on a chair; and the pressure sensing device II is arranged on a desk. The anti-lost device has the beneficial effects of being not required to carry about at every time when in use, being capable of reminding a user in time as the standing and sitting actions of a person are associated with the smart switch of a power supply, and being good in operability.
Description
Technical field
The utility model patent relates to a kind of circuit arrangement, especially a kind of anti-something lost dropping control device.
Background technology
At present, a kind of loss prevention device that existing development occurs comprises handset and machine tool two parts, and the user can input the title of wanting anti-lost article by letter key, shows the title that article are lost when article are lost on liquid crystal display.The patent No. is: 200910013869 " a kind of loss prevention device " and the patent No. are that 200720143485 " a kind of Oblivion-proof prompting device for portable article " is exactly such device.But the user needs to be with two machines--machine tool and handset in use, but also needs the input Item Title, quite bothers when using for a long time.
Summary of the invention
Technical problem to be solved in the utility model is: overcome existing loss prevention device and use inconvenient deficiency, a kind of prompting prevents from losing the smart circuit device that falls, this alarm set in time reminding user falls article, as long as and one-time fix to be arranged on tables and chairs when using and just can use for a long time, do not need to carry at every turn.
The utility model solves the technical scheme that adopts: a kind of anti-something lost dropping control device, comprise pressure sensitive device one and pressure sensitive device two, described pressure sensitive device one be connected pressure sensitive device two and be connected with the signal conditioning package electric signal respectively, described signal conditioning package is connected with the warning device electric signal, described pressure sensitive device one inside is equipped with intelligent switch, described pressure sensitive device one is arranged on chair, and pressure sensitive device two is arranged on desk.
The beneficial effects of the utility model are, do not need during use to carry at every turn, and people's the intelligent switch of sitting with power supply that rises interrelates, and in time reminding user, have operability preferably, can also allow the student take away voluntarily the rubbish that remains in desk.
Description of drawings
Fig. 1 is the utility model process flow diagram.
Embodiment
As shown in Figure 1, when pressure sensitive device one not during pressurized (nobody takes a seat), the intelligent switch acquiescence is closed, pressure sensitive device one is delivered to message handler to pressurized signal not, and message handler checks whether pressurized of pressure sensitive device two, if pressurized (without omitting article) not, message handler does not send alerting signal to warning device, if pressurized (the omission article are arranged), message handler sends alerting signal to warning device, and warning device warning reminding people has thing to lose; When pressure sensitive device pressurized (have people present), intelligent switch is opened, and sends signal to signal conditioning package, and after message handler was received signal, message handler did not send alerting signal to warning device.
Claims (1)
1. prevent losing dropping control device for one kind, it is characterized in that: comprise pressure sensitive device one and pressure sensitive device two, described pressure sensitive device one be connected pressure sensitive device two and be connected with the signal conditioning package electric signal respectively, described signal conditioning package is connected with the warning device electric signal, described pressure sensitive device one inside is equipped with intelligent switch, described pressure sensitive device one is arranged on chair, and described pressure sensitive device two is arranged on desk.
