The present invention relates to a method of selecting and using a pattern, an inspection method for detecting an abnormal state by checking an operation state of a controller, and a neon trans controller equipped with these functions.

It is no exaggeration to say that modern times are the days of advertising and promotion. The streets are wild with advertisements of shops and companies, and billboards such as neon signs are used to express the contents they want to advertise. These billboards are equipped with neon tubes and try to make them more visible and accurate by humans by controlling them with a controller. Therefore, the neon transformer controller for controlling these neon tubes is usually to turn on and off the neon tube by interrupting the alternating current flowing through the neon transformer, a conventional example thereof has been posted in FIG.

FIG. 6 is an exemplary circuit diagram of a zero bolt detection unit in the present invention, and FIG. 7 is a waveform diagram output from each part of the zero bolt detection circuit shown in FIG. 6. Hereinafter, the zero bolt detection method will be described in more detail with reference to these two drawings and FIG. 3.

As described above, the zero bolt detection unit 122 senses the point where the polarity of the voltage crosses the alternating voltage, that is, the zero volt point, in order to synchronize with the passage of time in the microcontroller 112 and the signal generator 123. Generate a signal.

When AC power as shown in FIG. 7 (a) is applied to ① and 의 of FIG. 6, the pulse flow as shown in FIG. 7 (b) flows in ②. After the pulse flows through the resistor R3, the portion higher than the zener voltage is absorbed by the zener diode as shown in (c) of FIG. 7 by the diode D2, and only the signal indicated by the black portion in the drawing is lower.

8 is a waveform diagram illustrating a voltage control method using the pattern data of the present invention, and FIG. 9 is a flowchart sequentially showing the voltage control method using the pattern data of the present invention. The voltage control method by the pattern data of the present invention will be described in detail with reference to these drawings and the aforementioned FIG. 3 as follows.

When power is supplied, all variables such as speed counter and data comparison counter are initialized. When the detection signal (Fig. 8 (d)) is input from the zero bolt detection unit 122, the microcontroller 112 increases the speed counter and compares it with the set value. (Steps I, II, III) If the set values match, the speed counter is initialized, the data is read from the pattern data memory 121, and transmitted to the signal generator 123.

The signal generator 123 initializes the data comparison counter when the detection signal (d) of FIG. 8 is input from the zero bolt detector 122. As soon as the initialization is completed, the clock generator generates a reference signal to increase the data comparison counter. (Steps IV and V) At this time, the data comparison counter increases from 0 to 255, at a speed of 30,720 per second. It is increased 120 times per second from 0 to 255.

The signal generator 123 then compares the pattern data input from the microcontroller 112 with the data comparison counter value increased above. (Step VI) In this case, when the pattern data value is large, the current ON signal is generated. And when the pattern data value is small, the current OFF signal is transmitted to the data latch 124. (Steps Ⅷ, Ⅷ, Ⅸ) This current control signal is the maximum as shown in (f) of FIG. When driving the current at 20% of brightness, signal as ⓐ, when driving 50% current at maximum brightness, as ⓑ, and when driving 75% current at maximum brightness, it appears as ⓒ.

In this way, since the current control signal input to the data latch 124 is a digital signal, it is converted into a signal (DC 12V) required by the current driver 132 through the optical converter 131 and then applied to the current driver 132. do. The current driver 132 interrupts the pulse current (Fig. 8 (b)) supplied from the rectifying unit 134 when the current control signal (Fig. 8 (f)) is inputted to the neon trans drive current (Fig. 8 (f)). g)) is supplied to the overcurrent protection unit 135. The overcurrent protection unit 135 controls the brightness of the neon tube by applying the thus supplied neon transformer driving current to the neon transformer. At this time, the overcurrent protection unit 135 composed of a fuse (FUSE) when the current supplied from the current driver 132 excessively flows, that is, when the current flows to the current driver 132 when the overcurrent flows to the current The driving unit 132 is prevented from being overheated and broken.

In this way, the brightness of the neon tube is controlled by supplying a current to the neon transformer for the time set in the data using the pattern data.

FIG. 10 is a circuit diagram illustrating a preferred embodiment for implementing a voltage control method using pattern data of the present invention. The above-described voltage control method may be implemented with the same circuit as in FIG. 10. As shown in (a) of FIG. 8, the signal generated in ① of FIG. 10 is the waveform as shown in FIG. 8 (b), and ② and ③ of FIG. 10 is the waveform as shown in FIG. In addition, the signal generated in ④ of FIG. 10 forms a waveform as shown in FIG. 8 (g).

On the other hand, the present invention is to enable the user to input 1 to 8 pattern data to use the pattern freely. This will be described in detail with reference to FIGS. 11 and 12.

11 is a configuration diagram of a pattern data memory for implementing the pattern data selection method of the present invention. 12A to 12D illustrate embodiments in which pattern data is loaded in the memory illustrated in FIG. 11, and shows patterns in which pattern data is loaded in the memory according to the type of pattern data. The pattern data selection method will now be described with reference to these figures and FIG. 3 described above.

As shown in FIG. 11, a user first inputs a desired number of pattern data into the pattern data memory 121. At this time, the number of input pattern data is 1 to 8. When the power is turned on, the microcontroller 112 selects the pattern data selection signal selected by the operator based on the external input signal or the communication input signal input through the communication input terminal block 114 when there are a plurality of pattern data. ) The pattern data selection signal is used in connection with the upper address of the pattern data memory 121 and is maintained until the pattern data selection signal is updated with new data. For example, when the pattern data memory 121 is 4 Mbit, the address signals are 19 (A0 to A18), and when the pattern data is four, the pattern selection signals are two upper address signals (A17 and A18). The pattern data selected by the outputted pattern data selection signal is loaded from the pattern data memory 121 to the microcontroller 112 so that the changed new pattern data is applied to the neon billboard.

The data selection signal is different depending on the number of pattern data, but when there is one pattern data as in FIG. 12A, the data selection signal is not used. In case of two pattern data as in FIG. 12B, the data selection signal is used. Uses 1 bit (Bit). In addition, as shown in FIG. 12C, when there are four pattern data, the data selection signal uses two bits, and when there are eight pattern data as shown in FIG. 12D, the data selection signal uses three bits.

13A and 13B are views for explaining a controller abnormality check method of the present invention. 14 is a circuit diagram showing an embodiment of the output voltage detection sensor in the present invention.

In the steady state as shown in Fig. 13A, the "four" letter is displayed in red and the "on" letter is displayed in blue. However, due to a failure of the neon trans controller, as shown in FIG. 13B, if the letters are not normally lit, the contents to be delivered cannot be faithfully represented. In addition, it is not good for aesthetics, and can also cause great damage to the image of the product and the company to be promoted. Therefore, in order to overcome these shortcomings, it is most important to confirm the abnormality of the neon transformer controller in real time as in the present invention, and to promptly notify the operator of the abnormality in case of an error so that a quick action can be made.

Now, with reference to the above drawings and the above-described 3 and 8 will be described in detail with respect to the abnormality check method of the neon transformer controller of the present invention.

Then, the current driver 132 controls the pulsation current output from the rectifier 134 in accordance with this control signal and supplies a current to the output terminal block 133 through the overcurrent protection unit 135. Accordingly, when current starts to flow to the output terminal block 133 and becomes equal to or higher than the reference voltage shown in FIG. 8G, current flows in the diode D1 and PC1 as shown in FIG. As such, when a current flows in the PC1, the sensor output signal as shown in FIG. 8H is generated in the output signal OUT. In particular, the diode D1 emits light so as to easily find a fault position when a fault occurs in the controller, thereby facilitating confirmation of abnormality.

On the other hand, the signal generator 123 outputs the current driver control signal, and when the voltage output from the rectifier 134 is the highest, that is, the value of the data comparison counter is 127 (A, ⓑ, ⓒ in Fig. 8E). ) Latches the current driver control signal (FIG. 8F) and the output signal OUT and requests an interrupt to the microcontroller 112. The microcontroller 112 compares the sensor data signal (Fig. 8 (h)) and the current driver control signal (Fig. 8 (f)) when an interrupt request is received from the signal generator 123. It is determined that the controller does not operate normally and an error occurs. The error data generated in this way is stored in the error data memory 116 and transmitted to the operator through the relay system when requested by the operator.

15A and 15B are circuit diagrams showing other embodiments of the output voltage detection sensor in the present invention. As shown, the circuit of the output voltage detection sensor shown in FIG. 14 is designed using the comparator U1 as in 15A. Alternatively, the transistor Q1 may be used as shown in FIG. 15B.

As described above, the present invention has the effect of increasing the advertising effect in a variety of different colors by the method of controlling the neon transit so that light of various colors in the neon tube. In addition, since the operator can select and use a pattern arbitrarily by embedding various pattern data, it can not only attract people's attention with various expression patterns but also increase the advertising effect by highlighting the content. In addition, the present invention can detect the abnormal state by checking the operating state of the controller, it is possible to quickly cope with a failure in the controller.
