Definitions

  • Electrical connection and method of amplitude modulation for transmission of information in the power line 230 V is related to switchboards, power line cables, appliances and communication between them over the common power line network. This is primarily about dimming control of the lighting via power line cables without additional control cables.
  • Remote control of electrical appliances can be performed in several ways. Most common way is with usage of the additional communication wiring near power line cable. Appliances must be tailored to this function. This means that the appliance with its power circuits contains an input to which the communication wiring is connected. One can influence the activity of the unit through the communication wiring. The necessity for the existence of communication wiring creates a various problem issues in many situations. Therefore, there are methods of wireless communication.
  • radio -frequency communication There is also a method of wireless communications using electromagnetic radio waves, i.e. radio -frequency communication.
  • Each appliance is equipped with radio-frequency receiver and a demodulator so that the received information is properly demodulated and sent to the electric appliance.
  • the systems called ZigBee, Telea work in such way.
  • the new proposed solution does not pose specific requirements of the power line cables. It is simple, robust and resistant to interference.
  • SK UV Nr. 5243 discusses a similar principle, but does not enable demodulators to be addressable, so modulation is difficult to be practiced under this arrangement and there is little tolerance to voltage fluctuations.
  • the essence of the invention lies in the amplitude modulation and demodulation of the power line voltage.
  • the essence is electrical connection to perform amplitude modulation and method of amplitude modulation of the power line voltage 230 V in the power line cables.
  • the electrical connection for amplitude modulation in the power line voltage 230 V consists of modulator block and demodulator block, interconnected by power line cable with the fact that the demodulator block is connected to power control unit block, which is connected to the appliance block.
  • Demodulator block is connected by a switching or control unit of the appliance.
  • the essence of the invention is also method of amplitude modulation of the 230V power line voltage in the power line cables, according to the power line voltage amplitude of the modulator block achieved in a way that modulator block limits the amplitude of the power line voltage during the half period by a level proportional to the voltage modulation depth while the amplitude is limited according to the transmitted instruction.
  • Power line frequency is used as the synchronisation for the information transmission.
  • the demodulator block uses power line voltage half-period amplitude peak as the reference value with power line voltage half-period of opposite polarity amplitude peak information as the information carrier. More periods of power line voltage are used to transfer instruction.
  • Modulation depth is lesser than permissible fluctuation of power line voltage.
  • Modulation clock frequency is synchronized with the power line frequency.
  • the demodulator block is synchronized with the power line frequency.
  • Demodulation process starts with the first half period, the value of which differs from the reference value of the previous half-period and ends with evaluation of defined half-period cycles.
  • the evaluation process consists of two steps, demodulating and demodulated signal decoding.
  • Modulator is in the switchboard from which is the power line voltage distributed.
  • the modulator changes amplitude of the output power line voltage according to the selected protocol synchronously with the power line frequency. Number of amplitude modulation levels may be different. As an advantage, two levels are used for this purpose. The original level (as non- reduced) and reduced by about 5%.
  • Bit word is a combination of reduced and non-reduced supply voltage half periods with the final, defined number. Only one half-period is modulated. The positive or negative half-period is modulated. The second half-period is stable and serves as a reference for the evaluation circuit of the appliance. For reasons of power line voltage fluctuations the reference is required for us. Let us take the negative half-period and positive data period as the reference.
  • the evaluation circuit compares these half-periods. It always scans negative following by its comparison with the positive one. If they are the same, nothing happens. If reduced positive follows the negative, the register is started with a defined number of bit locations. In the case of eight-bit word, there will be eight locations. Levels are assigned to the positive half-period after the register start in this way: same positive half-period is at logical zero level and decreased half-period is at logical one level. After filling the register with the clock frequency synchronized by power line frequency are data transmitted for further processing and for executing commands such as light source dimming. Bit word may have various length and may contain different instructions. Value preceding the start of the register can be used as the reference value of the power line voltage.
  • Amplitude modulation and demodulation with comparison of reference voltage value has higher fault tolerance in power line network.
  • This method of communication is suitable for lighting control, whether internal or external. There is no need for further cable installation. This information gets to the appropriate location over the power line cables.
  • Fig.l there is a principal scheme of amplitude modulation electrical circuit serving to transmit the information over power line cables.
  • Fig.2, Fig.3, Fig.4 there are possible methods of amplitude modulation and evaluating information.
  • amplitude modulation in fig.l consists of a modulator block 1, demodulator block 2, power control unit block 3, appliance block 4, while the power control unit block 3 and appliance block 4 are connected together.
  • Modulator block 1 is connected to demodulator block 2 by the line 5.
  • the modulator affects only the positive half-period. It carries instruction on the value of information. Binary modulation is used. If the positive half-period peak value is equal to the negative - reference half-period, this means logic 0 for the evaluation circuit. If the positive half-period peak value is decreased, it means logical 1. The value of the positive half-period is always compared to the previous negative reference half-period. If the demodulator identifies reduced positive half-period, recording starts automatically in the register. The register records and stores data in amount of 18. Registry operation is clocked by power line frequency. After loading of the necessary number of data, the register passes stored data for processing. Decoding circuit evaluates the incoming series of logical zeros and ones and transmits them to the power control unit.
