Description of drawings
Fig. 1 is the theory diagram of signal controlling change-over panel of the present invention.
Embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.
As shown in Figure 1, signal controlling change-over panel of the present invention is comprised of programmable power supply, the first numerical value translation interface, second value translation interface, programmable power supply is connected (specifically can realize connecting by the RS485 bus) with a personal-machine interactive interface, the first numerical value translation interface, second value translation interface all are connected with programmable power supply.The first numerical value translation interface can also be connected with an input electricity measuring instrument, the second value translation interface can also be connected with an output electricity measuring instrument, programmable power supply, the first numerical value translation interface, second value translation interface all are connected with a LED driving power, programmable power supply also leaves short circuit current and is connected with one, and opening short circuit current can also be connected with a LED lamp.Take the voltage of LED driving power as example, the voltage actual value will be adjusted into a benchmark, how much current voltage numerical value is, deliver to human-computer interaction interface after all will the simulating signal of voltage value being changed into digital signal by the first numerical value translation interface, second value translation interface, and then deliver to programmable power supply, adjust voltage value after analyzing, and then deliver to human-computer interaction interface, see whether the voltage value after whether adjusting reaches standard, if do not reach, again deliver to programmable power supply, repeatedly adjust several times contrast, be as the criterion until numerical value reaches standard value.No matter be human-computer interaction interface in the middle of the whole process to programmable power supply or programmable power supply in this process of human-computer interaction interface, the first numerical value translation interface, second value translation interface are operating always, that is to say in the signals transmission of the first numerical value translation interface, second value translation interface and programmable power supply does not have sequencing, all carries out at the same time all the time.
Programmable power supply integrates the MCU(micro-control unit), can regulate autotransformer, relay switch, civil power is through programmable power supply transformation (0V ~ 300VAC), as the input power of LED driving power, input simultaneously electricity measuring instrument and detect the input characteristics that this end electric weight obtains the LED driving power; Programmable power supply and human-computer interaction interface consist of both-way communication by the RS485 bus, the setting parameter numeric data streams such as the change in voltage scope the when series of instructions of being sent by human-computer interaction interface such as manual open and close test key commands, programmable power supply test and the holding time of each process etc. are for the programmable power supply built-in MCU receives, processing, as the LED lamp end of one of process open, the action of short circuit relay mechanism and retention time etc.; Programmable power supply is connected to the relay signal and is connected with opening short circuit current, is sent open circuit signaling, the short-circuit signal of LED lamp end by the programmable power supply built-in MCU, opens short circuit current and carries out open circuit order, short circuit order.Principle that realize to set rated voltage is as follows: based on the user to different input voltage testing requirements, by the human-computer interaction interface parameter page is set and sets 0V ~ 300VAC arbitrary integer threshold voltage, this numerical value is received by the in-built MCU of programmable power supply by the RS485 bus, in the control procedure MCU based on current voltage value and the positive and negative error amount of setting value through PI(ratio, integral adjustment) process given governor motion regulated quantity, until be adjusted to (bearing accuracy of the present invention is ± 3%) in the permissible error scope.Based on MCU control is lower line voltage is made amplitude adjusted (0 ~ 300V scope), record synchronously the corresponding electrical quantity of driving power, then obtain the response of continuous dynamic tested driving power, provide authentic data or foundation for whether judge measurand (LED driving power) meets the requirements.Industry or standard-required LED driving power product must have output terminal short circuit and open circuit protecting function; and short circuit, the open circuit requirement of holding time are arranged; all can able to programmely automatically finish based on the MCU framework; the interval of acceptance that automatic and able to programme realization can be surveyed index to the LED driving power is set and judgement (sound and light of alarm); automatic and able to programme realization can survey tested driver index certified products important parameter record, produce daily sheet, automatic and able to programme realization can survey tested driver index unacceptable product important parameter record, produce a day alarm meter.
The present invention carries out the signal conversion by the first numerical value translation interface, second value translation interface, so just can operate by human-computer interaction interface, and is easy to operate, increases work efficiency.Human-computer interaction interface is communicated by letter with programmable power supply, input electricity meter, output electricity meter, in real time centralized displaying measurement, processing, record data and realization load end able to programme open circuit, short-circuit test.
Those skilled in the art can carry out various remodeling and change to the present invention.Therefore, the present invention has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
