Description

Technical Field

[0001] The present invention relates to the technical field of power data acquisition, and particularly to a three-phase HPLC broadband carrier module. Background Art

[0002] The power system is an electric energy production and consumption system composed of power plants, power transmission and transformation lines, power supply and distribution stations, and electricity consumption. In the power system, power lines are not only used to transmit electric energy, but also can be used as a communication medium to realize information transmission. Power line carrier communication (PLC) precisely utilizes this characteristic to transmit analog or digital signals at high speed through power lines. Currently, power line carrier communication has been widely applied in fields such as power management, lighting control, and remote meter reading.

[0003] In the prior art, for the transmission of power data through power line carrier communication, especially in the field of data transmission of carrier energy meters, the proximal end of the three-phase HPLC broadband carrier module is connected to the carrier energy meter, and the distal end communicates with the master station. It is powered by a capacitor as the power source. In a power outage state, data transmission can be achieved within a short period of time.

[0004] However, the capacitor provided in the existing broadband carrier module has been electrically connected to the broadband carrier chip all the time. Therefore, the maintenance time in a power outage state is relatively short. When communication fails, it is difficult to perform multiple data transmissions, resulting in the inability to report the data of the carrier energy meter in a power outage state.

Therefore, they do not have substantial technical significance.

[0041] Figure 1 It is a structural block diagram of a three-phase HPLC broadband carrier module provided by the present invention. Specific embodiments

[0042] The following specific embodiments illustrate the implementation manners of the present invention. Those familiar with this technology can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0043] In order to solve the technical problems existing in the prior art, in this embodiment, a three-phase HPLC broadband carrier module is provided. The proximal end is signal-connected to a carrier energy meter, and can collect the data of the carrier energy meter in real time. At the same time, the distal end is signal-connected to a master station. The broadband carrier module can transmit the collected data of the carrier energy meter to the master station. Specifically, as Figure 1 shown, it includes:

[0044] A broadband carrier chip, a carrier data sending unit, a carrier data receiving unit, a data signal coupling unit, a capacitor power supply unit, a capacitor power supply adjustment unit, a power supply data processing unit, and a data acquisition unit. Among them, the input end of the broadband carrier chip is signal-connected to the output end of the data acquisition unit, and the data acquisition unit is used to collect the relevant operation data of the carrier energy meter. The output end of the broadband carrier chip is signal-connected to the input end of the carrier data sending unit, and the input end of the broadband carrier chip is also signal-connected to the output end of the carrier data receiving unit. The output end of the carrier data sending unit and the input end of the carrier data receiving unit are signal-connected to the data signal coupling unit. The output end of the data acquisition unit is signal-connected to the input end of the power supply data processing unit. The output end of the power supply data processing unit is signal-connected to the input end of the capacitor power supply adjustment unit. The output end of the power supply data processing unit is connected to the capacitor power supply unit. The capacitor power supply unit is connected to the broadband carrier chip. The capacitor power supply adjustment unit is also signal-connected to the carrier data sending unit and the carrier data receiving unit.

[0045] As described above, the power supply data processing unit processes the relevant data collected by the data acquisition unit. At the same time, the capacitor power supply adjustment unit controls the capacitor power supply unit based on the relevant data fed back by the power supply data processing unit to provide electrical energy for the carrier data sending unit, and appropriately powers off and silences the capacitor power supply unit to save electrical energy.

[0046] Among them, the data acquisition unit is used to collect the power outage report data of the carrier watt-hour meter. The power supply data processing unit is used to receive the power outage report data transmitted by the data acquisition unit and process and calculate the power outage report receipt. The capacitor power supply adjustment unit is used to receive the calculation result of the power outage report data and adjust the power supply voltage of the capacitor power supply unit.

[0047] Specifically, the data acquisition unit is used to collect the power outage report data of the carrier watt-hour meter. The specific steps include:

[0048] Obtain the power outage trigger signal of the carrier watt-hour meter, that is, when the carrier watt-hour meter has a power outage, trigger the data collection command of the collection unit;

[0049] Based on the power outage trigger signal, obtain the power metering data, real-time power consumption data, remaining power data, remaining electricity bill data, and fault data;

[0050] Process the power metering data, real-time power consumption data, remaining power data, remaining electricity bill data, and fault data to obtain the power outage report data.

[0051] At the same time, the power supply data processing unit is used to receive the power outage report data transmitted by the data acquisition unit and process and calculate the power outage report receipt, including:

[0052] Obtain the power outage report data and calculate the data volume to be transmitted of the power outage report data; that is, after collecting the power metering data, real-time power consumption data, remaining power data, remaining electricity bill data, and fault data, calculate the total data volume of the above data, such as the total data volume is 200K.

[0053] Compare the data volume to be transmitted with the data transmission threshold, and determine the data transmission scheme based on the comparison result; set a threshold for each data transmission, and determine how to transmit the data based on whether the comparison result is greater than the data transmission threshold.

[0054] In one case, when the data volume to be transmitted is less than the data transmission threshold, direct transmission is performed;

[0055] Another case is that when the amount of data to be transmitted is greater than the data transmission threshold, the power outage report data is split into at least two sub-amounts of data to be transmitted, and each sub-amount of data to be transmitted is less than the data transmission threshold. For example, the power metering data and the real-time power consumption data are combined into one sub-amount of data to be transmitted, and the remaining power data, the remaining electricity bill data, and the fault data are combined into another sub-amount of data to be transmitted, so as to ensure that the two sub-amounts of data to be transmitted are lower than the data transmission threshold, thus facilitating the transmission of the amount of data to be transmitted.

[0056] Meanwhile, the capacitor power supply adjustment unit is used to receive the calculation result of the power outage report data and adjust the power supply voltage of the capacitor power supply unit, including:

[0057] Obtain the data transmission distance data with the master station and the preset data transmission rate data, and calculate the data transmission time of the amount of data to be transmitted, including:

[0058]

[0059] Wherein, L is the data transmission distance data, S is the preset data transmission rate data, and T 1 is the data transmission time.

[0060] Based on the calculated data transmission time and the amount of data to be transmitted, calculate the power supply voltage of the amount of data to be transmitted on the carrier data sending unit, including:

[0061]

[0062] Wherein, L is the data transmission distance data, S is the preset data transmission rate data, B is the amount of data to be transmitted, and V 0 is the power supply voltage, and V max is the maximum voltage.

[0063] Allocate the loaded voltage on the carrier data sending unit based on the obtained power supply voltage data.

[0064] Meanwhile, obtain the data transmission distance data with the master station and the preset data transmission rate data, and calculate the data transmission time of the amount of data to be transmitted, and also include:

[0065] Based on the obtained data transmission time, determine the reception time when the carrier data receiving unit receives the backhaul data;

[0066] Based on the data transmission time and the reception time, determine the silent time of the capacitor power supply unit.

[0067] Furthermore, the silent time is less than the sum of the data transmission time and the reception time, including:

[0068] T 3 <T 1 +T 2

[0069] Among them, T 1 is the data transmission time, T 2 is the reception time, and T 3 is the silent time.

[0070] As shown above, T 1 is the time for data to be transmitted from the broadband carrier module to the master station, and T 2 is the time when the data sent by the master station is received by the broadband carrier module. After the data is sent from the broadband carrier module, it is necessary to wait for a period of T 1 +T 2 to obtain feedback. In order to better save the power of the capacitor power supply unit, the electrical connection between the capacitor power supply unit and the broadband carrier chip, the carrier data sending unit, the carrier data receiving unit, etc. is cut off during this period, and after the silent time T 3 , the capacitor power supply unit is powered on again. Through this process, the electric energy of the capacitor power supply unit can be greatly saved and the power supply time can be extended.

[0071] The present application provides a three-phase HPLC broadband carrier module, which includes a broadband carrier chip, a carrier data sending unit, a carrier data receiving unit, a data signal coupling unit, a capacitor power supply unit, a capacitor power supply adjustment unit, a power supply data processing unit, and a data acquisition unit. The input end of the broadband carrier chip is signal-connected to the output end of the data acquisition unit, the output end of the broadband carrier chip is signal-connected to the input end of the carrier data sending unit, the input end of the broadband carrier chip is also signal-connected to the output end of the carrier data receiving unit, the output end of the carrier data sending unit and the input end of the carrier data receiving unit are signal-connected to the data signal coupling unit, the output end of the data acquisition unit is signal-connected to the input end of the power supply data processing unit, the output end of the power supply data processing unit is signal-connected to the input end of the capacitor power supply adjustment unit, the output end of the power supply data processing unit is connected to the capacitor power supply unit, the capacitor power supply unit is connected to the broadband carrier chip, and the capacitor power supply adjustment unit is also signal-connected to the carrier data sending unit and the carrier data receiving unit. By collecting the power outage report data and calculating the amount of data to be transmitted, and determining the transmission scheme according to the size of the amount of data to be transmitted. At the same time, based on the data transmission distance, data transmission rate, and the maximum voltage of the capacitor power supply unit, an optimized supply voltage is provided for the carrier data sending unit, so as to improve the data transmission effect. At the same time, considering the situation where the amount of data to be transmitted is relatively large, the amount of data to be transmitted is split into multiple sub-amounts of data to be transmitted, which is beneficial to the smoothness of data transmission. Moreover, by setting the silent time, the loss of the capacitor power supply unit in the power outage state is reduced, preparing for providing the voltage for secondary data transmission after the data transmission fails.

Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of the present invention claimed.
