Description
Technical field
The invention belongs to monitoring equipment field, relate in particular to a kind of Multifunctional liquid crystal and show commissioning device.
Background technology
Current safety monitoring commissioning device on the market generally shows dimensions as 2.4 cun to 3.5 cun left and right, and display effect is not ideal enough; And function ratio is more single, only support composite video signal input test (being the test of common simulation camera signal).In addition, " having " or " nothing " that it can only test video signal, intensity that can not test simulation camera video signal.And cannot test for signals such as VGA, HDMI in current security protection industry monitoring product, SDI.Single composite video signal is tested, and can not meet user's demand far away.
Summary of the invention
The object of the invention is to utilize at a kind of Multifunctional liquid crystal and show commissioning device, be intended to solve the display effect existing in existing safety monitoring commissioning device not ideal enough, function ratio is more single, only support composite video signal input test, " having " or " nothing " that can only test video signal, the problem that the signal such as intensity that can not test simulation camera video signal and VGA, HDMI in security protection industry monitoring product, SDI cannot be done to test.
The object of the present invention is to provide a kind of Multifunctional liquid crystal to show commissioning device, this equipment comprises liquid crystal display screen, VGA signal input interface, HDMI signal input interface, battery cover, DC12V output interface, video CVBS signal input interface, plastic casing; Described liquid crystal display screen is arranged on described plastic casing, described VGA signal input interface and HDMI signal input interface are arranged on the side of described plastic casing, described DC12V output interface and video CVBS signal input interface are arranged on the back side of described plastic casing, and described battery cover is arranged on described plastic casing.
Further, described Multifunctional liquid crystal shows that commissioning device adopts 5.6 cun of plastic casings, decoding mainboard, 5.6 cun of liquid crystal display screens, No. 5 batteries of four joints.
Multifunctional liquid crystal in the present invention shows commissioning device, adopts the liquid crystal display screen 1 of 5.6 cun, and the display size of relative 2.4 cun or 3.5 cun, can bring display effect more clearly; Abundant signal input interface makes commissioning device function no longer single, and workmen need not worry for job site has multiclass signal format to have no idea to test again; Can be in the situation that whole supervision control engineering have not been set up, front end signal collecting part and back end signal display section are carried out to system debug, effectively save human and material resources, financial resources, equipment volume of the present invention is small and exquisite, easy to carry, get final product work not accessing external power source, aspect engineering debug, have good practical value.
