Description

Automation equipment and method for producing bus-controlled television

The invention relates to an automatic device and method for producing a bus-controlled television set. Specifically, the present invention has developed an apparatus and method capable of high-speed production of bus-controlled televisions in a factory equipped with a bus-control device.

In conventional TV sets, each functional control unit (for example: multiple voice, voice signal processor, image signal processor, graphic circuit and picture-in-picture circuit, etc.) is controlled by a microcomputer (or system controller) The port receives the control signal and executes the corresponding function. Thus, since the microcomputer cannot perform other functions while controlling the relevant function control unit, the signal processing time is prolonged. Moreover, with the increase of such control functions, the burden on the microcomputer is getting heavier, the wiring is more complicated, and the PC board configuration area and the number of devices will increase accordingly. In this way, the system design is very difficult and the reliability is poor.

Therefore, the bus control method is adopted in the TV set. The microcomputer and each functional control unit are connected to each other through a serial data line and a serial clock line with bidirectional data transmission capability. In addition, each controlled functional control unit is assigned a corresponding dedicated address. In this way, when the microcomputer generates data and address information, the corresponding functional control units execute their respective control functions. This system is called the I ² C bus system, and this kind of TV is also called a bus-controlled TV.

In order to produce bus-controlled television sets, the factory is equipped with a bus-control device as shown in Figure 1. The figure shows a situation where a bus control television is being produced with a bus control device.

In the production method, both the bus control device 3 and the television set 1 are connected to a bus connector. In this case, the operating camera 2 and the bus control device 3 adjust the preset values of the television set 1 in accordance with the television test signal transmitted via the television test signal cable. This type of adjustment increases production time.

Therefore, an object of the present invention is to develop an automatic production apparatus for producing television sets by automatically testing the functions of the television sets in a factory equipped with a bus control apparatus.

Another object of the present invention is to develop an automated production method for producing television sets by automatically testing their functions in a factory equipped with bus control equipment.

The factory remote control 40 receives the remote control signal sent by the remote control signal generator 33 in the bus control device 30 and sends it to the TV set 20 . The remote control signal is used to set the automatic factory debugging mode to check the state of the fluorescent screen of the TV set 10 and select the corresponding function control signal of each control item.

The automatic connector 50 automatically connects the TV set 10 to the bus control device 30 according to the control signal output by the improved personal computer 32 through the control cable, and sends the TV test signal generated by the TV test signal generator 35 to the TV through the TV test signal cable.

However, the SDA and SCL lines can also be used to connect other functional control units to the microcomputer 12 here.

Fig. 4 shows a flow chart of the automated method for producing bus-controlled television sets proposed by the present invention. This method will be described below with reference to FIGS. 2 and 3 .

As shown in Figure 4, when the video camera 20 detects that the TV set 10 on the conveyor belt has been in place in the idle state, after the bus control device 30 recognizes the signal picked up by the video camera 20, it controls the automatic connector 50 to The TV 10 is connected to the bus control device 20, and the TV test signal generated by the TV test signal generator 35 is input into the TV 10 (steps 1 to 3).

Among them, the bus control items controlled by the TV test signal are listed in the table below. key bus control project 1 RD (Red Drive) 2 GD (Green Drive) 3 BD (Blue Drive) 4 RC (red cut off) 5 GC (Green Cutoff) 6 BC (blue cut-off) 7 SB (sub-brightness) 8 VA (Vertical Amplitude) 9 VS (vertical offset) 10 HS (horizontal offset)

After inputting the television test signal, under the control of the bus control device 30, the remote control signal corresponding to the factory commissioning key and the calling key is sent to the television set 10 by the factory remote controller 40, thereby establishing an automatic factory commissioning mode (steps S4 and S5 ).

It should be noted here that the factory remote control 40 has a receiver for receiving the remote control signal generated by the remote control signal generator 33 and a transmitter for sending the remote control signal to the remote control signal receiver 11. This remote control can be See US Patent No. 5,045,843.

After setting up the automatic factory commissioning mode, input the corresponding control items listed in the table above with the number keys on the factory remote controller 40, and select the corresponding corresponding control items (step S6).

Among them, in order to select the bus control item, a procedure of sequentially inputting numeric keys "2" to "9" into the TV 10 through the factory remote control 40 can be used.

For example, if the number key "2" is input to the TV set 10 through the factory remote controller 40, the microcomputer 12 will display the "GD" character data generated by the character data generator 14 after determining that the bus control item is "GD". In some cases, however, character data overlaps with image data on the CRT 16, preventing data from being read out. Therefore, character data can be blanked so that image data can be displayed without disturbance.

Here, the bus control device 30 utilizes the image signal captured by the camera 20 to determine the display state of the CRT 16, and utilizes the increase/decrease key on the factory remote controller 40 to change the control value for "GD" (step S7).

The bus control device 30 checks the display state of the CRT16 by the changed "GD" value through the camera 20, and if the display state is good, then sends the remote control signal for selecting other control item number keys.

Then, the control value for "GD" is stored in the E ² PROM 13 of the television 10 (step S8).

It is then determined whether all control items have been completed. If also control item is not completed, then return to step S6, if all control items have been completed, then cancel factory commissioning mode (step S9 to S10) with factory commissioning mode key or power key.

In addition, the bus control device 30 outputs a control signal to the automatic connector 50 through the control cable, cuts off the connection between the TV set 10 and the bus control device 30, and stops transmitting the TV test signal (step S11).

As described above, with the present invention, it is possible to automatically produce bus control televisions at high speed in a factory equipped with bus control equipment.
