The present invention relates to a control unit of a TV receiver installed in each room of a hospital, and in particular, to provide convenience and ease of use by using an electronic card without using coins as before.

Conventionally, a TV control device installed in a hospital is equipped with a coin inlet and a coin storage box, which has a large volume of the product, and a coin input method is adopted, so that the device frequently breaks down and charges even when the initial setting and the TV (TV) are off. Not only was this paid, but there was an uncomfortable problem in the management and collection of coins.

Therefore, the present invention has been made to solve the problems of the prior art, and by adopting the electronic card method without adopting the coin insertion method as in the conventional case, it can be used easily by a prepaid electronic card holder like a public telephone card. It is an object of the present invention to provide a hospital TV control device for solving the inconvenience of miniaturization, ease of management, and collection of coins.

The present invention for achieving the above object will be described in detail with reference to the accompanying drawings.

1 is a block diagram of the present invention, as shown therein, an electronic card lead / light unit 1 for storing an initial usage fee and a balance, and an electronic card protection unit 2 for preventing damage to an electronic card. ), A function selection switch (3) for selecting the balance of the card, the accumulated amount, and setting status, an external power use check unit (4) for checking the use of external power, and operations of each unit A microcontroller 5 for controlling, an inactive memory 6 for storing data such as function setting, fee, secret code, user code, etc., an external power supply 7 for controlling external power supply, a fee for use, It is comprised by the display part 8 which displays a balance and the accumulated amount setting state.

The operation and the effect of the present invention configured as described above will be described with reference to FIGS. 2 to 5.

First, the control operation of the microcontroller 5 checks the electronic card input / output status in the initialization state as shown in FIG. 2, and then checks the function selection switch state and then checks whether the external power is used or not.

Next, after checking the read state of the electronic card, the write state of the electronic card is checked and the result is displayed on the display unit 8.

On the other hand, the timer driving inside the microcontroller 5 increases the system time as shown in FIG. 3, performs the blinking operation of the display unit 8, and checks whether the external power is used or not. Check if the external power usage time is longer than the setting unit usage time, and if it is long, reduce the balance of the electronic card and end.

On the other hand, if the external power is not in use or the external power is shorter than the set unit, it will be terminated immediately.

The main routine control operation of the present invention shown in FIG. 2 will be described in more detail with reference to FIG.

First, the electronic card input / output check operation checks the electronic card input state as shown in (a) of FIG. 4 and supplies power when the electronic card is in the input state, and cuts off the power supply when the electronic card input state is not. Next, the check operation of the function selection switch 3 is checked by pressing the function selection switch as shown in Fig. 4 (b). Or exit immediately.

Next, the external power usage check operation detects whether the current is supplied from the outside as shown in (c) of FIG. 4 and checks whether the detection value at the stop is smaller than the detection value at the time of use. If it is big, it detects the stop status and exits.

Next, the electronic card read check operation checks whether the electronic card input elapsed time has passed the first predetermined time (one second) as shown in (d) of FIG. It is checked whether the second predetermined time (750 ms) has elapsed.

On the other hand, if the first predetermined time (for one second) has not elapsed, the process ends immediately. If the second predetermined time (750ms) does not pass, the process ends immediately.

If the elapse of the second predetermined time (750ms) is checked, the secret code of the electronic card is read, and if the secret code matches the secret code stored in the inactive memory 6, the electronic code is checked. After ending the card classification code (master card, test card, cash card).

If it does not match, it is determined that the negative electronic card is inserted and the power supply is stopped and then terminated.

Next, the electronic card write check operation sequentially checks whether a cash card, a test card, or a master card is used as shown in (e) of FIG. 4, and in the case of a cash card, checks whether the external power is used or not. Check if the time has elapsed.

If the external power is not in use, it is terminated immediately, and if the unit time has elapsed, it is checked whether the cash card balance is insufficient. If the balance is insufficient, the external power supply is stopped. If the balance is insufficient, the decrease value of the cash card balance is written. Then exit.

On the other hand, if it is not a cash card, check if it is a test card, and if it is a test card, end after the electronic card lead / write test.If it is not a test card, check whether it is a master card. The current detection values at the time of external power supply OFF and ON are respectively measured. After reading the user secret code, they are stored in a specific ROM and then terminated.

Finally, the operation of the display unit 8 checks whether the electronic card is in the input state as shown in (f) of FIG. 4 and ends after displaying the CARD if it is not the input state. In this case, FALL blinks and if it is not input, it checks whether it is Master card input status.

If the master card is in the input state, check whether the predetermined time (for 5 seconds) has elapsed after the OFF display. If the predetermined time (for 5 seconds) has not elapsed, immediately end. If the predetermined time (for 5 seconds) has elapsed, display again after the TV ON. Check if the time has elapsed (for 5 seconds). If the predetermined time has not elapsed, it ends immediately. If the predetermined time has elapsed, GOOD displays.

On the other hand, if it is not the master card input status, check whether it is a cash card input status. If it is not a cash card input status, check whether it is a test card, and if it is not a test card, return to the FALL blinking display process. do.

At this time, it is checked whether the external power supply is used even when the cash card is input.

In this way, it checks whether the external power supply is used and if it is not in use, it displays HOLD and if it is in use, it checks whether the cash balance is insufficient. If it is insufficient, it displays 0 and stops the external power supply and ends. Otherwise, display the cash card balance and exit.

Figure 5 shows an example of the installation configuration of the device of the present invention, it is used attached to any location on the side of the TV (TV) receiver, where 9 represents the electronic card insertion hole, 3b is the balance display flashing light emitting element, 3c is OK Display Blinking Light emitting device.

As described above, the present invention is a control device of a hospital TV receiver, by adopting the electronic card method without adopting the coin input method as in the prior art, it can be used simply if only the electronic card, as well as coins By not using the product, the miniaturization of the product, ease of management, and the inconvenience of collecting coins can be greatly improved.
