Abstract
The invention discloses a handheld terminal with a sound-light alarm device. The handheld terminal with the sound-light alarm device comprises an inductor, a main alarm and a handheld terminal body. The inductor and the main alarm are each internally provided with a signal transmitting device, a signal receiving device and a buzzer. The main alarm is arranged on the handheld terminal body. The inductor is carried around a user of the handheld terminal. After the handheld terminal is lost, the inductor can receive wireless signals sent by the main alarm within a certain distance range, once the distance exceeds the set distance, the buzzer on the inductor gives an alarm, and a prompt indicating that the handheld terminal is lost is given to the user of the handheld terminal; the farther the distance is, the louder the alarm sound of the buzzer is, when the user returns to the set distance range to look for the handheld terminal, the buzzer on the inductor stops giving the alarm, an LED lamp on the main alarm starts to flicker, and therefore the user can find the handheld terminal conveniently.
Description
Technical field
The present invention relates to a kind of handheld terminal with acoustic-optic alarm, particularly relate to a kind of high precision Big Dipper handheld terminal with acoustic-optic alarm, belong to electronic anti-theft field.
Background technology
High precision Beidou handset is a kind of industrial handheld terminal integrating GPS/BDS location, 3G communication, intelligent call, function of wireless talkback, can use under complex environment in the wild.High precision Beidou handset adopts android system, ARM dual core processor, is widely used in the fields such as intelligent patrol detection, rivers and lakes generaI investigation, monitoring logistics transportation, forestry examination, store management, one dimension two dimension code reading, urban operating mechanism generaI investigation, electrical production and marketing.When using in complex environment in the wild, handheld terminal is easily lost and is found inconvenience.
Summary of the invention
In view of this, an object of the present invention is to provide a kind of handheld terminal with acoustic-optic alarm.
Object of the present invention is realized by following technical scheme:
With a handheld terminal for acoustic-optic alarm, comprise inductor, main alarm and handheld terminal body, in described inductor and main alarm, be provided with sender unit and signal receiving device; In addition, described inductor is provided with hummer, main alarm is provided with LED.
Described main alarm is arranged on handheld terminal body, and described inductor is carried with by the user of handheld terminal.
The mode of operation of described inductor is divided into normal mode of operation and looks for pattern, and the sender unit in inductor is wireless signal emission under the pattern of looking for only.
In the normal mode of operation, the signal receiving device in described inductor receives the wireless signal that the sender unit in main alarm sends, and when not receiving this wireless signal, the hummer buzzing on inductor is reported to the police.
Under the pattern of looking for, when the wireless signal that the sender unit that the signal receiving device in described main alarm receives in inductor sends, the LED in main alarm starts flicker.
On the dismountable shell being connected to handheld terminal body of described main alarm;
Described main alarm magnetic absorption is on the metal shell of handheld terminal body.
Principle of work:
Described inductor has two kinds of mode of operations, is respectively normal mode of operation and looks for pattern, and user is according to needing to set suitable alarm distance in inductor.Sender unit in inductor is wireless signal emission under the pattern of looking for only.
When using handheld terminal in the wild in complex environment, open the power switch of main alarm and inductor, now inductor is in normal mode of operation, main alarm wireless signal emission, within the scope of the alarm distance of setting, inductor can receive the wireless signal that main alarm sends, and the hummer now on inductor can not send warning.When distance between user and handheld terminal exceedes the alarm distance of setting, inductor does not receive the wireless signal that main alarm sends, and the hummer now on inductor will send warning, and prompting user handheld terminal now exceedes alarm distance; The distance of handheld terminal and user is far away, and on main alarm, the chimes of doom of hummer is larger.
Now, inductor is switched to the pattern of looking for by user, under the pattern of looking for, and inductor wireless signal emission, when the distance between user and handheld terminal is in the alarm distance set, the hummer stop alarm on inductor; And main alarm can receive the wireless signal that inductor sends, the LED now on main alarm starts flicker, and person easy to use finds.
In order to prevent false alarm, the inductor carried with can be closed when the user of handheld terminal initiatively leaves.
Beneficial effect
Handheld terminal with acoustic-optic alarm of the present invention has the function of bidirectional alarming, searches conveniently, reduce Loss Rate, can avoid causing loss unnecessary, as the data etc. that handheld terminal recorded and stored after handheld terminal is lost.
Accompanying drawing explanation
The alarm principle figure of this handheld terminal of Fig. 1.
Wherein, 1-inductor; 2-main alarm; 3-handheld terminal body.
Embodiment
Below in conjunction with the drawings and specific embodiments in detail the present invention is described in detail, but is not limited thereto.
The present embodiment provides a kind of handheld terminal with acoustic-optic alarm, realizes bidirectional alarming function by the cooperation of inductor 1 and main alarm 2.
As shown in Figure 1, magnetic absorption main alarm 2 on the metal shell of handheld terminal body 3, described inductor 1 is carried with by the user of handheld terminal.Sender unit and signal receiving device is provided with in described inductor 1 and main alarm 2; In addition, described inductor 1 is provided with hummer, main alarm 2 is provided with LED.
The mode of operation of described inductor 1 is divided into normal mode of operation and looks for pattern, and the sender unit in inductor 1 is wireless signal emission under the pattern of looking for only.
In the normal mode of operation, the signal receiving device in described inductor 1 receives the wireless signal that the sender unit in main alarm 2 sends, and when not receiving this wireless signal, the hummer buzzing on inductor 1 is reported to the police.
Under the pattern of looking for, when the signal receiving device in described main alarm 2 receives the wireless signal that the sender unit in inductor 1 sends, the LED in main alarm 2 starts flicker, finds with person easy to use.
The present invention includes but be not limited to above embodiment, every any equivalent replacement of carrying out under the principle of spirit of the present invention or local improvement, all will be considered as within protection scope of the present invention.
