Abstract
The invention discloses a start control system for an on-vehicle LED display equipment. The system comprises a module power supply and a main power supply relay, wherein a power supply circuit of the LED display equipment is formed by connecting the main power supply relay with an on-vehicle storage cell; and after an on-vehicle generator starts, electricity is transmitted to the module power supply connected with the generator for filter rectification and voltage regulation, then the electricity is inputted to the main power supply relay to ensure that the generator is electrified and connected with the power supply circuit of the LED display equipment. The system also comprises a maintenance/automatic switch with an automatic path connected between the on-vehicle generator and the module power supply as well as a maintenance path for directly connecting the on-vehicle storage cell and the main power supply relay. Because an automobile generator is used to control current source for a coil of the main power supply relay, when a vehicle is not started, the main power supply relay of the LED display equipment can not be turned on, and can not obtain electricity from the on-vehicle storage cell so as to carry out protection and control.
Description
Technical field
The present invention relates to a kind of electric-control system, specifically is a kind of start control system for on-vehicle LED display equipment.
Background technology
Present vehicle LED read-out is public transport means (bus especially; taxicar etc.) vehicle mounted LED screen on is used very extensive; but great majority all are small sizes; color mono-literal screen; continuous development along with the LED technique of display; cost constantly descends; manifestation is more and more abundanter and reliability is also more and more higher; therefore; it also will be more and more widely in the application aspect vehicle-mounted; but it is corresponding; the power consumption that it constantly increases; the original electric system of vehicle is exerted a certain influence, how it is carried out control corresponding and protection when starting, perfect solution is not arranged at present as yet.
Summary of the invention
Technical matters to be solved by this invention provides a kind of start control system for on-vehicle LED display equipment, it can to vehicle electrical systems play better controlled and protective effect, particularly under the bigger situation of LED power of display equipment.
For solving the problems of the technologies described above, a kind of start control system for on-vehicle LED display equipment of the present invention comprises modular power source and main power relay, and wherein, the feed circuit of LED display equipment are connected to form by main power relay and Vehicular accumulator cell; Mobile generator starts back transmission of electricity to connected modular power source and carries out the filter rectification voltage stabilizing, and then the input main power relay, makes this relay get the feed circuit of electric connection LED display equipment; Also comprise maintenance/automatic switch, the automatic path of this switch is connected between mobile generator and the modular power source, and the maintenance of this switch is with Vehicular accumulator cell and main power relay direct connection.
As a preferred embodiment of the present invention, described start-up control system also comprises the time closing circuit, and described time closing circuit function delays time main power relay between modular power source and main power relay.
As further preferred version of the present invention, described start-up control system comprises that also the time-delay cut off is arranged between above-mentioned maintenance and the main power relay, makes the main power relay delay cut-off.
As another preferred version of the present invention, the modular power source of described start-up control system adopts the scope load module power supply of 9～36V, and its output voltage is 12V.
Owing to utilize automobile current generator to be the coil control current of main power relay source, thereby make LED display equipment main power relay when vehicle does not start to connect, can not protect and control from the Vehicular accumulator cell power taking.In addition, the time closing circuit is set makes the LED display equipment avoid the influence of vehicle repeated priming, be beneficial to the maintenance steady-working state; Time-delay cut off luxus consumption storage battery electric energy can avoid keeping in repair the time is set, causes the vehicle launch difficulty.The different automobile of the compatible power-supply system of the made native system of wide region load module power supply.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structured flowchart of the preferred embodiment for the present invention.
The specific embodiment
Fig. 1 is the structured flowchart of a kind of start control system for on-vehicle LED display equipment of the present invention.As seen from the figure, the mobile generator in this preferred implementation is connected with modular power source by the automatic path in the maintenance/automatic switch, and modular power source is connected with main power relay by the time closing circuit then; In addition, also having a kind of bonded assembly to exist, is exactly that Vehicular accumulator cell is connected in the time-delay cut off by the maintenance in the maintenance/automatic switch, is connected with main power relay then.It can also be seen that by figure the feed circuit of LED display equipment are connected to form by main power relay and Vehicular accumulator cell.
Occupation mode one, under the normal condition of service, maintenance/automatic switch uses automatic path, after starting, mobile generator produces electric current, this electric current directly is transfused to connected modular power source, modular power source carries out the filter rectification voltage stabilizing to this electric current, imports main power relay after the time-delay through the time closing circuit again, makes it get the feed circuit of electric connection LED display equipment.Owing to utilize automobile current generator to be the coil control current of main power relay source, thereby make LED display equipment main power relay when vehicle does not start to connect, can not protect and control from the Vehicular accumulator cell power taking.In addition, the time closing circuit is set makes the LED display equipment avoid the influence of vehicle repeated priming, be beneficial to the maintenance steady-working state.
Occupation mode two, vehicle be in dead ship condition and carry out the maintenance of LED display and the situation of maintenance under, maintenance/automatic switch working service path, directly connect Vehicular accumulator cell, electric current makes it get the feed circuit of electric connection LED display equipment through time-delay cut off input main power relay.The time closing circuit is controlled its automatic cutout behind certain hour, in order to avoid luxus consumption storage battery electric energy, cause the vehicle launch difficulty.
Because common manned vehicle is different with commercial passenger vehicle power-supply system, divide DC12V and DC24V, the charging signals voltage of mobile generator output also has difference, be compatible two kinds of signals, thereby, in an embodiment of the present invention, modular power source adopts the scope load module power supply of 9～36V, and its output voltage is 12V.
For avoiding the influence of vehicle repeated priming, make LED display equipment stable operation, in an embodiment of the present invention, the time closing circuit is set to export after 10 seconds.
Vehicle be in dead ship condition and carry out the maintenance of LED display and maintenance, when needing directly to connect battery feed, in the embodiments of the invention, the cut off of delaying time is set to automatic cutout after 3 minutes, in order to avoid luxus consumption storage battery electric energy, cause the vehicle launch difficulty.
Certainly, in practice, can replace modular power source with filtering and mu balanced circuit; but just can not realize compatible 12V and 24V, promptly need to use two kinds of different relays, this conversion; belong to the technology of the present invention feature is simply replaced, still fall within protection scope of the present invention.
