Abstract
A display screen with alarming function is provided, which comprises a display screen box body and a box door, and is characterized in that: the display screen is provided with a microprocessor. The utility model also comprises a detection circuit arranged at the box door of the display screen box body; one end of the detection circuit is connected to the input/output port of the microprocessor and the other end is earthed.
Description
[technical field]
The utility model is about a kind of display device, but refers to a kind of display device of outdoor burglar alarm especially.
[background technology]
Outdoor LED display, be deployed in the open air, stolen easily when people such as night are few, chamber door is pried open by malice easily, how when theft takes place, can report to the police automatically, in time notify the maintainer to hurry to the scene, be a large amount of out of doors problems that LED display faced of disposing of installing.The general method that adopts manual inspection, cost height and inefficiency can't effectively find to steal the generation of destruction rapidly.
Therefore, prior art is improved, the display screen with anti-theft alarm function that provide a kind of high-level efficiency, cost is low, safe coefficient is high, performance is good is real in necessary.
[summary of the invention]
The display screen that the purpose of this utility model is to provide a kind of high-level efficiency, cost is low, safe coefficient is high, performance is good with anti-theft alarm function.
To achieve these goals, the utility model adopts following technical scheme:
A kind of display screen with warning function is provided, it comprises display screen box body, chamber door, be provided with microprocessor MCU in the display screen, this display screen with warning function also comprises the testing circuit of the chamber door position that is installed in display screen box body, this testing circuit one terminates to the I/O I/O port of microprocessor MCU, other end ground connection.
This testing circuit can be to comprise the door switch that is installed on the chamber door, this door switch is in the state of connection in the display screen box body closure, the input/output end port of display screen microprocessor is that ground connection is low level, this door switch opens circuit when display screen box body is opened, and the input/output end port of display screen microprocessor is unsettled to be high level.
This microprocessor is connected with several leaflet unit.Number leaflet unit can adopt CDMA or GPRS to transmit warning message.Change by the level on the I/O I/O mouth that detects LED display microprocessor MCU, can judge whether chamber door is opened, when detecting chamber door and be opened, pass by CDMA or GPRS number warning message is passed back.
This testing circuit can also adopt another embodiment, and the conductive filament that can adopt polyphone to be bonded on the glass chamber door is realized testing circuit.
This conductive filament adopts ultra-fine copper wire, is adhesive on the glass chamber door with optics.Do not influence the translucent effect of glass like this, do not examine and to discover.
This conductive filament is ground connection when the glass chamber door is intact, the I/O I/O port of display screen microprocessor MCU is the low level of ground connection, this conductive filament disconnects in the glass box gate crasher, and the I/O I/O port of display screen microprocessor MCU is unsettled, is high level.
This microprocessor MCU is connected with several leaflet unit, and this is counted leaflet unit and adopts CDMA or GPRS number to pass.Change by the level on the I/O I/O mouth that detects LED display microprocessor MCU, can judge whether glass is broken, when detecting the glass fragmentation, warning message is passed back by CDMA or GPRS number biography.
Compared with prior art, of the present utility model have a following beneficial effect:
The display screen that the utlity model has warning function is installed the door switch circuit of ground connection on chamber door, and connect the I/O I/O port of microprocessor MCU, accurately judge the on off state of chamber door, when chamber door is opened by malice, can in time detect door switch disconnects, thereby give the alarm signal, degree of safety height, performance are good, and simple in structure, cost is low.
[description of drawings]
Fig. 1 is the synoptic diagram that the utlity model has the display screen of warning function.
[embodiment]
As shown in Figure 1, the utlity model has the display screen of warning function, it comprises display screen box body, chamber door, is installed in the door switch circuit in the display screen box body, be provided with microprocessor MCU in the display screen, this on-off circuit comprises door switch, one terminates to the I/O I/O port of microprocessor MCU, other end ground connection.This microprocessor MCU is connected with CDMA/GPRS and counts leaflet unit.
This on-off circuit switch when chamber door is closed cuts out, this circuit ground, the I/O I/O port of display screen microprocessor MCU is the low level of ground connection, switch is opened when chamber door is opened, this circuit breaker, the I/O I/O port of display screen microprocessor MCU is unsettled, is high level.Microprocessor MCU detects high level and then sends alerting signal, counts leaflet unit by CDMA/GPRS and transmits alerting signal.As shown in Figure 1.
This testing circuit that has in the display screen of warning function can also adopt other embodiments to substitute, as shown in Figure 1, the circuit of a ground connection can be installed at the glass chamber door, this circuit adopts the ultra-fine copper wire that does not influence glass chamber door light transmission to make electric action, this ultra-fine copper wire is used up and is learned that to be adhesive in chamber door on glass, connects the I/O I/O port of display screen microprocessor MCU.When the glass chamber door is intact, this circuit ground, the I/O I/O port of display screen microprocessor MCU is the low level of ground connection, when the glass chamber door is broken, ultra-fine copper wire fracture, this circuit breaker, the I/O I/O port of display screen microprocessor MCU is unsettled, is high level.Microprocessor MCU detects high level and then sends alerting signal, counts leaflet unit by CDMA/GPRS and transmits alerting signal.As shown in Figure 1.This embodiment is the further perfect anti-theft alarm function of door switch circuit.
The above only is preferred embodiment of the present utility model, and protection domain of the present utility model is not limited thereto, and those of skill in the art are any to be included within the utility model protection domain based on non-material change on the technical solutions of the utility model.
