Abstract

The present invention relates to a power line transmission means of a remote control signal in a ballast for a fluorescent lamp. In the related art, a method of completely removing a sinusoidal upper wave on a power line or transmitting a data corresponding phase modulation wave is known. The problem is that the upper waveform uses a signal that has been completely truncated, thereby increasing the loss of its transmission power. In the latter case, there is a problem of ensuring the data transmission quality due to ambient noise and waveform distortion.

The present invention provides a fluorescent lamp address and dimming control information set on the input side of the system so that the transmit side of the sine wave can be used as two types of phase control waves on the transmitting side of the system so as to improve the problems of the prior art. According to the logic 1 and 0, the transmission means for transmitting the data and the two kinds of phase control waves transmitted from the transmission means are checked to match the predetermined fluorescent lamp address, and the digital data for the dimming control information is checked. The present invention provides a power line transmission method of a remote control signal and a circuit thereof in an electronic ballast for fluorescent lamps, which comprises a processing means integrally with a receiving means for converting a value into an analog and providing the same to a fluorescent lamp.

The present invention relates to a power line transmission means for remote group (Dimming) control signal for remote control transmission of the group number of the electronic ballast for fluorescent lamps and the dimming control signal using a power line, which is particularly such a remote control transmission means By minimizing the loss of transmit power that can be generated by cutting and transmitting the waveform transmitted by partial erasing, the power transmission efficiency of the control signal can be actively improved and the power transmission of the remote control signal can be improved. The present invention relates to a power line transmission system of a remote control signal in an electronic ballast that can be reliably achieved.

Means have been known for remotely controlling a group of electronic ballasts for fluorescent lamps using power lines or for dimming individual fluorescent lamps, of which the typical type has been performed by the following means.

In this case, the transmitting end for the remote control is a signal that completely removes the sinusoidal top of the remote control signal on the power line and transmits the period N at intervals.

However, this means that the power transmission efficiency is low due to the small effective value and the crest factor of the transmission power of the remote control signal, and on the one hand, the distortion of the power waveform may cause other equipment (EMI) to fail. This is not desirable because it also increases the power loss by sending the missing pulse again to determine the period.

Another type is known, in which data is transmitted as a waveform-modulated signal at a corresponding phase. However, this also causes noise and distortion when there is a large amount of dimming or a group of ballasts. It has been a problem because it has a disadvantage that is difficult to distinguish.

An object of the present invention is to implement a simple system for transmitting a remote control signal using a power line to solve the problems of the prior art as described above and to minimize the transmission failure while increasing the power transmission efficiency compared to the conventional method One electronic ballast is to provide a power line transmission system of a remote control signal.

According to the present invention, in order to make the sinusoidal phase wave into two kinds of phase control waves, the transmit side of the system is a phase control corresponding to logic 1 and 0 according to the fluorescent lamp address and dimming control information set at the input side. A transmission means for transmitting data and a two-phase phase control wave transmitted from the transmission means to check whether the address matches a predetermined fluorescent lamp address, and converts the digital value of the dimming control information into an analog and provides it to the fluorescent lamp side. There is provided a power line transmission method of a remote control signal to an electronic ballast for a fluorescent lamp, characterized in that the processing means including the receiving means and integrally.

Another feature of the present invention is a remote control transmission transmitter for generating a waveform cut signal of the upper wave side corresponding to the binary code bit of the transmission data and transmitting it on the power line, and a control signal sent through the power line from the remote control transmission transmitter side. It is characterized by the remote control signal power line transmission circuit in an electronic ballast consisting of an associated configuration with a remote control transmission receiver which decrypts and processes the signal.

Hereinafter, by referring to this in more detail with the accompanying drawings will be understood more specific features of the present invention.

That is, FIG. 1 shows a remote control transmission transmitter used in the remote control signal power line transmission system according to the present invention.

Here, a power supply unit 1 which is connected to an AC single phase power line which is a normal power line to provide a system power supply, and a transmission side zero crossing detector 2 which is connected to the power supply unit 1 and detects whether a sine wave phase on the power line is zero; A transmission-side microcomputer 3 that is connected to the output of the zero-cross detector 2 and receives an interrupt signal from the zero-cross detector 2 and controls a waveform cut SCR switch 10 or the like on the power line side; A manual ballast switch (5) and a manual light control switch (6) connected to an input port of the microcomputer (3) for inputting an electronic ballast address and dimming information of a remote site required by a system user; A remote control receiver 4 connected to an input port and receiving an operation signal provided from an external remote control transmitter, the manual ballast switch 5 and the dimming switch 6 and a remote control means Which has been selected by manual remote control switch 7, a configuration that includes a clock generator, such as the transmission side (8) to provide a drive clock to the microcomputer (3).

In addition, the power supply unit 1 of the transmitter is adapted to supply a relay drive power supply in the microcomputer 3 and the system, which outputs the output voltage of the power transformer 20V to 15V and 5V, respectively. C. was used, and the ZERO-CROSSING detector 2 consists of a diode, a zediode and two transistors.

In the system, the ballast group number and dimming information are inputted from the user switch in the current manual mode and from the remote control in the remote control mode. This was done in an infinite loop.

Further, in the transmitting side microcomputer 3, the remote control transmission receiver corresponding to the remote control transmission transmitter of the first embodiment is shown as in FIG.

Here, a power supply unit 11 that connects to the power line to provide driving power to the system, a reception side zero crossing detector 12 connected to the power supply unit 11 to detect a zero crossing state, and the zero crossing detector 12 A receiving side microcomputer 13 for controlling the system following the output of the output signal as an interrupt signal, a receiving side clock oscillator 14 for providing a driving clock to the microcomputer 13, and the microcomputer ( 13) is connected to the output side, and has a related configuration with the DA converter 15 for converting a digital signal into an analog dimming control signal.

2A shows a transmission signal setting program 100 mounted in the transmission side microcomputer 3.

Here, the system is initialized at the start stage, and then it is checked whether the manual key has been pressed (steps 101 and 102). In step 102, if Y (Yes), the address of the remote fluorescent lamp to be lit is input (step 103), and the system reads the manual key value (step 104).

If N in step 102, a remote control value such as dimming is read (step 105), and the process proceeds to step 102.

In addition, the transmission data transmission program 200 for data transmission processing using the power line in the system is shown as (b).

In this case, it is checked whether the transfer is completed from the start step (step 201), where Y goes to return, and when N goes off, the relay is turned off (step 202).

After step 202, each data bit is transferred (step 203), and a series of processing steps are performed after the relay is opened (step 204).

4 (a) and (b) show the reception data processing program 300 and the reception data reading program 400 associated with FIG.

Here, the reception data processing program 300 initializes the system at the start step and detects whether there is a signal (steps 301, 302). Here, if the signal is Y, dimming data is read (step 303).

After the step 303, the address data is read (step 304), the address is correct (step 305), and if Y, the digital value for the dimming signal is converted to analog and provided to the system (step 306). If N, go to step 301.

The reception data reading program 400 as shown in (b) checks whether there is an interruption at 90 degrees (step 401), and if Y, the data is read as logic 1 and stored (steps 405 and 404). In step 401, it is checked whether N is 135 degrees (step 402), and if Y, data is read as logical 0 (step 403), and data is stored.

If N in step 402, the system is initialized (step 406), and a series of processing steps to return are performed.

The present invention of such a configuration is as follows.

That is, in the remote control transmitter according to the present invention of the first embodiment, the power supply unit 1 connected to the power line provides driving power required for the system, while the transmission side zero crossing detector 2 generates a square wave that is synchronized with the power line signal. An interrupt is generated to the sending side microcomputer 3.

The system microcomputer 3 is interrupted at the polling edge of every 60 Hz sine wave from the moment of interruption, and from this point on, the trigger time of the SCR switch 10 is determined.

In the SCR switch 10, the period from the interrupt point to the trigger point is a time when the signal is deleted from the upper wave portion of the power line, and the SCR switch 10 maintains the original waveform for the remaining time of the upper wave. The system microcomputer 3 calculates the time point at which the upper wave of the power signal is removed in the 90 degree (logical value 1) or 135 degree (logical value 0) phase, and at that time, the trigger circuit 9 To generate a trigger signal.

The trigger circuit 9 amplifies the current, separates the system from the power line, and applies a trigger pulse to the SCR switch 10.

In addition, the microcomputer 3 connected to the clock generator 8 is a ballast required by the user through the remote controller receiver 4, the manual ballast switch 5, and the manual light control switch 6 by the manual remote control setting switch 7; Enter the address and dimming information.

In the system microcomputer 3, the system on the transmission side is driven by the system programs 100 and 200 as shown in Figs. 2 (a) and (b).

That is, here, as shown in (a), the transmission signal setting program 100 initializes the system and checks whether the manual key has been pressed (steps 101 and 102). At this time, if the manual key is pressed, the address of the fluorescent lamp to be turned on remotely is input (step 103), and the system reads the manual key value (step 104).

If N in step 102, the input is processed by reading a remote control value such as dimming (step 105). In the interrupt situation as shown in (b), the transmission data transfer program 200 is driven.

In other words, if there is data already transmitted from the interruption step, it is checked whether the transfer is completed, and the transfer is not completed and the relay is turned off (step 202).

After step 202, each data bit is transferred (step 203), the relay is turned on (step 204), and the interrupt service routine is exited.

Data transmitted through the power line from the transmission transmitter side is received and processed by the remote control transmission receiver side provided on the electronic ballast side of the fluorescent lamp as shown in FIG.

On the remote control transmission receiver side, the power supply unit 11 supplies system power, and the receiving side zero crossing detector 12 converts the input power signal into a square wave and inverts its phase.

At this time, the receiving side microcomputer 13 connected to the clock generator 14 receives the signal of the zero-crossing detector 12 as an interrupt terminal, and the microcomputer 13 receives the interrupt signal at the rising edge from the point where the interrupt is applied. Calculate the time to the converted point in time.

The calculated time is changed to the received data, and when the ballast group number on the receiving side and the received group number match, the dimming data is output as a dimming signal through the DA converter 15.

In addition, the system microcomputer 13 checks whether the fluorescent lamp of the corresponding address is selected from the predetermined fluorescent lamp group by the reception data processing program 300 and the reception data reading program 400 as shown in FIGS. 4A and 4B. The dimming control value of the predetermined fluorescent lamp is read again to dimming the fluorescent lamp.

That is, the reception data processing program 300 initializes the system at the start step and detects whether there is a transmission signal (steps 301, 302). If there is a signal, first reads address data (step 304) and checks whether the address is correct. Subsequently (step 305), if the address is that of the fluorescent lamp, the digital value for the dimming signal is converted to analog and sent to the electronic ballast side of the fluorescent lamp.

Also, in the reception data reading program 400 as shown in (b), if there is an interrupt, it is checked whether the data is 90 degrees (step 401). If the data is 90 degrees, the data is read as logic 1 and the data is stored (steps 405 and 404). . In step 401, it is checked whether it is 90 degrees or 135 degrees (step 402). If it is 135 degrees, the data is read as logic 0 (step 403) and data is stored.

In the present invention, in the electronic ballast of the fluorescent lamp, these groups remotely control the dimming control by using the power line, and generate a signal in which the wave is cut at an arbitrary phase within the upper wave on the power line, and including the start and end signals. By encoding and transmitting the group signal and the dimming signal, loss of transmission power can be reduced as compared with the conventional method in which two signals whose upper waves are completely cut are transmitted at intervals of N periods. Compared with the conventional method of transmitting a waveform modulated signal at a phase, it is advantageous that a reliable data transmission is possible due to transmission noise and distortion.
