Along with led chip and Development of Packaging Technology, LED is showing and lighting field has obtained the development of advancing by leaps and bounds that LED has the characteristics of low energy consumption and high life, is that other light emitting source is incomparable.
Existing led controller has two kinds: a kind of is isochronous controller, its control shows the signal source real-time Transmission synchronously to led display unit, it (can be digital signal such as DVI interface signal that the signal source of isochronous controller is come the input signal of self-controller outside, the LVDS interface signal, the HDMI interface signal, TFT digital interface signal or other digital interface signals, or simulating signal such as AV interface signal, other analog signal interface signals such as S terminal interface signal, or through optical fiber, Ethernet, the programme signal that delivering paths such as less radio-frequency transmit); Another kind is the off line controller: i.e. control is read the program and the control that are stored in the storage medium and is shown in led display unit, the signal source of off line controller is the program that is stored in the local storage, and storer can be storage mediums such as hard disk, USB flash disk, CF card, SD card.
Because the programme source of isochronous controller is the controller external input signal, if the programme content of outside input does not exist, led display unit is display program normally just; And the programme source of off line controller is the programme content that is stored in the controller internal storage medium, and is if the user needs the interim necessary updated stored device of programme content of changing, very inconvenient.
The utility model content
Technical problem to be solved in the utility model is to propose a kind of synchronous off line integral LED controller that is applied to various LED screens, LED fluorescent tube, LED billboard etc., and has this led controller LED display device, to realize that the control of synchro control and off line combines, flexible switching program makes things convenient for the user.
For addressing the above problem, the utility model discloses a kind of synchronous off line integral LED controller, and it comprises: the data acquisition receiving circuit that is used to gather external input signal; Be used to store the storer of displaying contents; The displaying contents that is used for receiving the output data of described data acquisition receiving circuit or reading described storer is handled, and for led display unit provides the signal processing unit of shows signal, it connects described data acquisition receiving circuit and described storer; Be used for as the output data of data acquisition receiving circuit as described in the signal processing unit selective reception as described in the pre-conditioned control or the control module of the displaying contents of storer as described in reading, it connects described signal processing unit.
More excellent, described control module comprises: the unit that is provided with that is used for the parameter setting; Be used for detecting described signal processing unit and be output data that receives described data acquisition receiving circuit or the detecting unit that reads the displaying contents of described storer when the signal source of pre-treatment; Be used for the testing result of detecting unit as described and in conjunction with the switch unit of the described signal processing unit switching signal source of pre-conditioned control, it connects described detecting unit.
More excellent, described switch unit comprises real-time handover module and timing handover module.
More excellent, described signal processing unit is MCU processor, FPGA processor or asic processor.
More excellent, described signal processing unit can separate setting with described control module, also can integratedly be arranged at a system level chip (System On Chip, SOC) among.
Compared with prior art, the utlity model has following beneficial effect:
The utility model is improved the shortcoming of two class led controllers, and two quasi-controllers are integrated in one, and both can realize synchro control, also can realize off line control, and flexible switching program makes things convenient for the user.
Description of drawings
Fig. 1 is the structural representation of a preferred embodiment of the utility model.
Fig. 2 is the structural representation of another preferred embodiment of the utility model.
Embodiment
In view of two known class led controllers all have intrinsic shortcoming, the utility model is improved the shortcoming of two class led controllers, and two quasi-controllers are integrated in one, both can realize synchro control, also can realize off line control, flexible switching program makes things convenient for the user.
As shown in Figure 1.Present embodiment comprises: data acquisition receiving circuit 110, storer 120, signal processing unit 130, control module 140 and led display unit 150.
Wherein, data acquisition receiving circuit 110 is used to gather outside input signal, and the data of gathering are inputed to signal processing unit 130, offers led display unit 150 after being handled by signal processing unit 130 and shows; Simultaneously, after signal processing unit 130 can also read storage from storer 120 content is handled, offer led display unit 150 and show.That is to say that signal processing unit 130 can offer in 2 signal sources (one of them is outside input signal, and another is the content of storage in the storer 120) any one led display unit 150 and show after handling.
For guaranteeing that signal processing unit 130 can be according to user's requirement or setting, selection offers led display unit 150 with synchronous control mode with the input signal of outside and shows, or read the content of storage and offer led display unit 150 from storer 120 with the off line control mode and show, therefore, the utility model passes through signal processing unit 130 external control modules 140, and this control module 140 is MCU processor, FPGA, asic processor or selects to handle.
Wherein, control module 140 comprises: what be used for the parameter setting is provided with unit 141; Be used for detecting described signal processing unit 130 and be output data that receives described data acquisition receiving circuit 110 or the detecting unit 142 that reads the displaying contents of described storer 120 when the signal source of pre-treatment; Be used for the testing result of detecting unit 142 as described and in conjunction with the switch unit 143 of described signal processing unit 130 switching signal sources of pre-conditioned control, it connects described detecting unit 142.Simultaneously, be the requirement that the carrying out of satisfying the user switched in real time and regularly switch, real-time handover module that can in switch unit 143, be provided for switching in real time and the timing handover module that carries out regularly switching.
Such as, when the signal source of led display unit 150 current broadcasts goes wrong, as: external signal is interrupted or storer 120 damages, can and switch to another signal source fast by control module 140 real-time these faults of detection and show, obtain better assurance thereby can make the program demonstration of some important events or play.
Certainly, the user also can need or the personal preference as reality, at control module 140 the various conditioned disjunction modes that switch in the control signal source is set by unit 141 is set, thereby selects for the user provides more demonstrations, to further facilitate the user.Therefore, as shown in Figure 2, in order to satisfy the demand for control of user individual, can be arranged at a system level chip (System On Chip is SOC) among 20 described signal processing unit 130 and described control module 140 are integrated.
