Description
Affiliated technical field
The present invention relates to a kind of operating mode switching apparatus, relate in particular to a kind of the elephant in the plasma display digitizers such as (PDP-Plasma Display Panel), when being necessary the download system program or utilizing PC to control, the mode converting device of can finishing the work automatically.
Background technology
Usually in order to use the RS232C communication between download system software PC and the PDP in the flexible memory (flex memory) of PDP (Plasma Display Panel).
Pass through the RS232C communication with PC, the PDP module is operated or is controlled, or download system software.
After opening PDP, determine whether carrying out normal running or download system software according to HIGH/LOW (high/low) value that starts sign (BOOT ID), in the loop, must set in advance the switch of determining to start sign, so that when download system software, use for this reason.
Fig. 1 is in the traditional PDP module, and decision starts the figure of the switch of sign.
As shown in Figure 1, be provided with switch 10 in a side of PDP module, whether the button 11 on the above-mentioned switch 10 is pressed and different startup values of statistical indicant occurred.
That is, when the button 11 on the switch 10 is not pressed as yet, as shown in Figure 2,, apply the 3.3v power supply for the startup sign because 3.3v applies voltage and do not have ground connection.
Thereby, just apply voltage and start the PDP module and carry out general operation or control model with 3.3v.
On the contrary, when the button 11 on the switch 10 was pressed, as shown in Figure 3, because 3.3v applies voltage by switch 10 ground connection, therefore giving the startup voltage that sign applies was 0v.
Thereby the PDP module is just with downloading mode work, and can the download system program.
There is the possibility of user's maloperation in aforesaid switch, so operated by rotary motion is in place that the user is not easy to touch.
But this switch is provided with the position, the fabricator is told bring inconvenience in the use, also has the shortcoming that is not easy to be provided with.
In addition, because the special mounting switch must improve manufacturing expense.
Summary of the invention
The present invention its objective is that for the problem that solves above-mentioned existence proposes providing a kind of is not installing under the situation of switch in addition, also can finish the operating mode switching apparatus of download state or state of a control working mode change automatically.
Operating mode switching apparatus of the present invention is made of following components: in order to be connected the required connectivity port with a plurality of joints of complete operation/control or download system software with PC; Can be connected with above-mentioned connectivity port, and the conversion port of two plugs is housed; One end links to each other with the model selection loop, two electric connections that the other end is connected with above-mentioned connectivity port or conversion port; When the other end of above-mentioned two electric connections directly linked to each other with the connectivity port, the model selection loop was coupled with certain voltage, was operation/control model thereby make mode of operation; When the other end of these two electric connections was connected with the connectivity port by conversion port, the model selection loop was grounded, and was to download mode of operation thereby make mode of operation.
Above-mentioned conversion port is the RS232C cable.
Effect of the present invention is as follows:
The present invention does not need to be provided with in addition under the situation of switch, and the operating mode switching apparatus that is transformed into download state or operation/state of a control automatically is provided, and this is a big advantage.

Embodiment
Below, with reference to accompanying drawing, operating mode switching apparatus of the present invention is described in detail below.
Fig. 4 is operating mode switching apparatus figure of the present invention
With reference to Fig. 4 as seen, the present invention includes following components: in order to be connected the required connectivity port with a plurality of joints 20 of complete operation/control or download system software with PC; Can be connected with above-mentioned connectivity port, and the conversion port 30 of two plugs is housed; Can be connected with above-mentioned connectivity port or conversion port, and ground connection one of in two plugs that are connected with above-mentioned conversion port, another loop with decision power supply or mode of operation links to each other, be grounded as if just being connected with conversion port, be defined as mode of operation, if be connected and add that to the loop certain voltage decides the model selection loop 40 of mode of operation with the connectivity port.
Be described in more detail as follows: connectivity port 20 is connected with conversion port 30 on Fig. 4, and conversion port 30 is connected with model selection loop 40.
In the above-mentioned pattern, the voltage ground connection of 3.3v, apply 0v voltage for microprocessor 41 by No. 7 on the conversion port 30 and No. 8 joints.According to the voltage decision mode of operation of being added, come work by the download pattern during 0v.
Above-mentioned connectivity port 20, an one example are to link to each other with the RS232C cable.
And above-mentioned conversion port 30 is selected the reason of No. 7 and No. 8 joints, is owing to No. 7 and No. 8 just in time obsolete causes of joint in the RS232C cableport, so the selection of electric connection can not changed when not using the RS232C cable.
In addition, though not expression on figure replaces No. 7 and No. 8 joints play other joints that determine the mode of operation effect, can be undertaken by other communication modes.
So just can transmit the information of download, other control signals of input and output.
Fig. 5 is in the operating mode switching apparatus of the present invention, the loop-coupled structural drawing of connectivity port and model selection.
As shown in Figure 5, when connectivity port 20 was not connected by conversion port 30 with model selection loop 40, then the electrical connection of No. 7 and No. 8 joints disconnected, and therefore microprocessor 41 is applied 3.3v voltage.When applying 3.3v voltage, just by operation or the work of Control work pattern, can utilize other joints to operate or control by PC this moment.
Thus, the present invention is different with the method for using switch in the past, and only whether the use according to conversion port 30 decides mode of operation.
Fig. 6 is an operating mode switching apparatus workflow diagram of the present invention.
As shown in Figure 6, at first give loop power supply after, the user couples together (S100) with connectivity port and model selection loop.
When directly connectivity port and model selection loop being coupled together, No. 7 and No. 8 joint electricity disconnect, and the value that starts sign just becomes HIGH (height), just by operation/control model work (S110) (S140) (S150).
On the contrary, if the connectivity port is connected with conversion port and conversion port and model selection loop-coupled the time, No. 7 and No. 8 joints electrically contact, and the value that starts sign just becomes LOW (low), just presses download mode of operation work (S110) (S120) (S130).
As mentioned above, the present invention does not need switch is set in addition, utilizes the mode of operation that conversion port just can decision-making circuit.
