Description

Technical Field

[0001] The present invention relates to the technical field of power supply systems, and more specifically, to an adaptive cable compensation system for implantable power supply cables. Background Art

[0002] For wired power supply systems, the material and length of the power supply cable have different requirements in different application scenarios. Changes in the cable material and length will also bring about changes in the cable resistance. In addition, the power consumption at the power-consuming end will also change with the variation of application requirements. The conventional approach is to determine the power supply current on the power supply cable based on the power consumption under typical and worst-case operating conditions at the power-consuming end on the premise of determining the cable material and length, so as to evaluate the line loss of the power supply cable.

[0003] Then, the evaluated line loss is added to the power supply voltage at the power supply end. The disadvantages of this method are as follows: 1) It cannot adapt to changes in the material and length of the power supply cable: Changes in the material and length of the power supply cable will result in changes in the resistance, thus requiring re-evaluation of the line loss and readjustment of the power supply voltage at the power supply end.

[0004] 2) It cannot meet the changing requirements of power consumption at the power-consuming end: Changes in power consumption at the power-consuming end, especially when the power consumption at the power-consuming end increases with the change of application requirements, will lead to an increase in line loss. The increase in line loss requires readjustment of the power supply voltage at the power supply end.

[0005] 3) It cannot meet the requirements of low power consumption: On the premise of ensuring the normal operation of the power-consuming end, the power supply voltage at the power supply end will greatly affect the overall power consumption of the system. However, in the conventional approach, the power supply voltage at the power supply end is fixed and cannot be flexibly adjusted. Summary of the Invention

[0006] The purpose of the present invention is to solve the drawbacks existing in the prior art, and to propose an adaptive cable compensation system for implantable power supply cables.

[0007] To solve the above problems, the present invention adopts the following technical solutions:

[0008] An adaptive cable compensation system for implantable power supply cables, comprising a power supply end and a power-consuming end:

[0009] The power supply end includes a power supply end main control, an adjustable voltage power supply unit, and an output power protection unit;

[0010] The adjustable voltage power supply unit is responsible for providing the output voltage of the power supply end to the power-consuming end, and receiving the control of the power supply end main control, and adjusting the output voltage value according to the control signal;

[0011] The output power protection unit is responsible for overvoltage, overcurrent, short-circuit protection and processing of the power supply output by the power supply end;

[0012] The main controller at the power supply end is used to control the output voltage of the adjustable voltage power supply unit and make voltage adjustment decisions based on the voltage values collected at the power consumption end;

[0013] The power consumption end includes a main controller at the power consumption end, an input power protection unit, a voltage sampling unit, and a functional circuit unit;

[0014] The input power protection unit is responsible for protecting against reverse connection, overvoltage, overcurrent, and short - circuit of the input power supply and the power supply at the power consumption end or handling such situations;

[0015] The voltage sampling unit collects the input power supply voltage by the main controller at the power consumption end through a sampling control signal;

[0016] The functional circuit unit is used to execute preset power consumption functions;

[0017] The main controller at the power consumption end is used to detect abnormalities in the input power supply and is interconnected with the main controller at the power supply end through a communication bus.

[0018] As a further solution of the present invention: The processing at the power supply end includes the following steps:

[0019] S1. Turn on the output power supply;

[0020] S2. The output power protection unit determines whether there are overvoltage, overcurrent, and short - circuit abnormalities in the output power supply. If there are abnormalities, it reports and processes the abnormalities; if the output power supply is normal, it attempts to obtain the voltage value at the power consumption end through the communication bus;

[0021] S3. Judge the normal reading of the voltage value. If the voltage value reading is abnormal, such as the voltage value cannot be read or the communication bus is abnormal, it attempts to increase the output voltage; if the voltage value reading is normal, it judges and processes the read voltage value;

[0022] S4. The main controller at the power supply end makes a decision on the output voltage adjustment according to the obtained voltage value and the voltage adjustment strategy, increasing / decreasing or maintaining the current output voltage;

[0023] S5. After the output voltage adjusted by the adjustable voltage power supply unit passes through the abnormal judgment of the input power protection unit and the acquisition of the voltage value at the power consumption end, it makes a decision on the output voltage adjustment again according to the obtained voltage value and the voltage adjustment strategy, increasing / decreasing or maintaining the current output voltage; and loops in turn;

[0024] S6. Turn off the output voltage and end the process.

[0025] As a further solution of the present invention: The processing at the power consumption end includes the following steps:

[0026] S1. The input power protection unit detects abnormalities in the input power supply. If the power supply is abnormal, it enters the abnormal reporting and handling program; if the power supply is normal, the voltage sampling unit samples the input voltage.

[0027] S2. Input voltage sampling; the master control at the power consumption end obtains the input voltage sampling value from the voltage sampling unit through the sampling control signal.

[0028] S3. The master control at the power supply end reports the voltage sampling value through the communication bus.

[0029] S4. The input power protection unit determines abnormalities in the input power supply again, samples the voltage, and then reports the sampled voltage value through the communication bus, and so on in a loop.

[0030] As a further solution of the present invention: The communication bus is a bidirectional communication bus, which is used for data transmission and command control between the power supply end and the power consumption end.

[0031] Compared with the prior art, the advantages of the present invention are as follows:

[0032] The present invention can adapt to power supply cables with different line resistances, and at the same time, the power supply end can adjust the voltage of the power supply end in a timely manner according to the change of the power consumption of the power consumption end, so that it can not only meet the power supply requirements of the power consumption end under different power supply cables and different power consumptions, but also reduce the overall power consumption of the system as much as possible.
