As shown in fig. 3, an embodiment of the present invention provides a method for adjusting a signal transmission rate of a power line, which is applied to a host of a power line system, where the power line system is composed of a host and a slave cluster mounted on a power line, and the method for adjusting a signal transmission rate of a power line includes:

S1: responding to the trigger of the debug mode, and sending a debug instruction to the slave cluster based on a first communication rate so as to enable the slave cluster to enter the debug mode;

s2: constructing a communication enhancement frame at least based on a preset confirmation code, wherein the confirmation code is used for determining a second communication rate adopted when the host transmits the communication enhancement frame, and the second communication rate is not less than the first communication rate;

s3: transmitting the communication enhancement frame to the slave cluster based on a second communication rate, and obtaining first feedback information generated by a first slave based on the communication enhancement frame, wherein the first slave is one or more slaves in the slave cluster;

s4: verifying the first feedback information, and determining a second slave machine capable of correctly analyzing the content of the communication enhancement frame from the first slave machine based on a verification result, wherein the second slave machine is a slave machine capable of communicating based on a second communication rate;

s5: and determining an adjustment strategy corresponding to the second communication rate based on the proportion of the second slave machine to the slave machine cluster.

The scheme based on the embodiment can enable the host to adaptively adjust the transmission rate of the power line of the slave cluster, ensure that the transmission rate can be matched with the performance of most or all of the slaves, and ensure that the slaves can normally transmit and receive signal data. The power line system is high in overall flexibility, wide in application range, and after the speed is adjusted, each slave can stably operate, and normal operation of the power line system can be effectively guaranteed after the speed is adjusted.

Further, the method further comprises:

s6: after power-on, a group inspection frame is sent to the slave cluster through a third communication rate, and second feedback information fed back by part or all of the slaves in the slave cluster through responding to the group inspection frame is obtained, wherein the second feedback information represents that the slaves are currently in an on-line state;

s7: determining a slave machine in an online state based on the second feedback information;

s8: and when the proportion of the slave machines in the online state relative to the slave machine cluster meets a preset threshold, determining that the trigger condition of the debugging mode is met.

For example, after power-up, the host may first send a group patrol frame at a third communication rate to collect on-line device information on the bus (power line), that is, determine which slaves are on-line, and count the number of on-line devices, and also determine the identity of the slaves, such as the slave code. The third communication rate is specifically indefinite, and may be set along with the communication rate of the patrol frame at the last power-up, or may be set by user-definition, for example, setting a slower communication rate, or setting a relatively faster communication rate, etc. After the state of the online slave device is confirmed, the host can issue a debug instruction, such as by broadcasting a command, so as to inform all online slave devices to enter a debug mode.

In the embodiment, the comparison is performed by determining that the current system state meets the triggering condition of the debug mode, for example, the total number of slaves in the original slave cluster is compared, if the calculated duty ratio is calculated, if the proportional relationship between the current number of slaves and the total number of slaves meets the preset threshold representing the system abnormality, the master can determine that the current power line system may have a situation that some slaves may be in the online state, but limited by the communication rate, so that information cannot be fed back, or information cannot be analyzed to realize feedback, so that the master can determine that the current system state meets the triggering condition of the debug mode, and needs to adjust the communication rate of the slaves.

In yet another embodiment, for the determination of the triggering condition, the method further comprises:

s9: under a normal running state, determining the quantity of third feedback information received in a preset period, wherein each third feedback information corresponds to one slave;

s10: and when the duty ratio of the quantity of the third feedback information relative to the total quantity of the slaves in the slave cluster meets a preset threshold, determining that the triggering condition of the debugging mode is met.

The method comprises the steps that when a host finds that a slave in a system has communication abnormality in a period of time, a command for entering a debugging mode is automatically issued, so that the host and the slave enter the debugging mode, and pulse width is properly adjusted through the method, namely, the communication rate is adjusted, so that all the slaves can send and receive signals normally, and communication is normal.

Or after obtaining the instruction input by the debugger, the host controls the host to enter the debugging mode in response to the input instruction, and simultaneously informs the slave in the system to enter the debugging mode.

Further, in this embodiment, the constructing the communication enhancement frame based at least on the preset acknowledgement code includes:

s11: determining the acknowledgement code based at least on a second communication rate, the acknowledgement code consisting of one or more of 0 and 1;

s12: and constructing the communication enhancement frame by combining the confirmation code based on a preset format, wherein the preset format is a frame header, the confirmation code, a frame type, an address, data and a slave code return area.

The sync acknowledgement code is specific content, such as 10101, and each 1 and 0 has a corresponding code width, and the slave can determine the communication rate by calculating and measuring the code element width of the acknowledgement code, that is, determine the communication rate of sending the communication enhancement frame.

Upon verifying the first feedback information, comprising:

s13: verifying whether the format of the first feedback information is the preset format;

s14: if yes, verifying whether the corresponding slave machine code return area part in the first feedback information contains information about frame type, address and data returned by the slave machine, wherein the information about the frame type, the address and the data is obtained by analyzing the content of the communication enhancement frame by the slave machine according to a second communication rate, and the second communication rate is determined by measuring the pulse width of the confirmation code.

For example, during verification, it is first verified whether the first feedback information is configured according to the format of the frame header, the acknowledgement code, the frame type, the address, the data, and the slave return code area. If so, further verifying the correctness of the content of the slave code region part in the first feedback information, namely whether the part of data is of correct frame type, address and data. And after the secondary machine determines the second communication rate through the confirmation code calculation, analyzing the content positioned behind the confirmation code in the communication enhancement frame based on the second communication rate, thereby obtaining corresponding code return data.

Specifically, as shown in fig. 5, in this embodiment, after receiving an instruction that the bus enters the debug mode, a plurality of slaves on the bus are converted into the debug mode, and the rate detection engine in the slave chip counts the high level and the low level and the acknowledgement code in the signal frame waveform through the clock, so as to calculate and obtain the pulse width of the synchronous acknowledgement code issued by the host. Then, the rate control module in the slave chip performs an average process on the multiple pulse widths to obtain the communication rate of the frame, namely, the second communication rate, and records the communication rate, so as to adjust the rate settings of the RX receiving module and the TX transmitting module according to the communication rate. After the slave updates the rate configuration, the command content after the confirmation code in the communication enhancement frame is analyzed according to the new rate setting, and the code returning is performed based on the analysis result. If the analysis fails, the code is not returned. After the host acquires the first feedback information fed back by the slave, sequentially verifying the format and the content of the first feedback information, when the verification is successful, the slave providing the first feedback information can be determined to be the equipment capable of realizing communication based on the second communication rate, and the slave failing to feed back the first feedback information and the slave corresponding to the first feedback information failing to verify are determined to be the equipment incapable of carrying out communication at the second communication rate.

In an alternative embodiment, the determining the adjustment policy corresponding to the second communication rate based on the ratio of the second slave to the slave cluster includes:

s15: when the proportion of the second slave machine relative to the slave machine cluster meets a first threshold value, the second communication rate is adjusted downwards to form a fourth communication rate;

s16: when the proportion of the second slave machine relative to the slave machine cluster meets a second threshold value, the second communication rate is adjusted upwards to form a fifth communication rate;

s17: updating an acknowledgement code based on the fourth communication rate or the fifth communication rate, and constructing a new communication enhancement frame based on the updated acknowledgement code, so as to detect the slave cluster again based on the new communication enhancement frame, and determine a third slave capable of communicating at the fourth communication rate or the fifth communication rate;

s18: repeating the steps until the obtained proportion of the fourth slave machine to the slave machine cluster meets a third threshold value, determining the current communication rate, informing the slave machine cluster to operate at the current communication rate, exiting the debugging mode, and entering a normal operation mode; or (b)

S19: and when the proportion of the second slave machine to the slave machine cluster meets the third threshold, informing the slave machine cluster to operate at a second communication rate, exiting the debugging mode and entering a normal operation mode.

In this embodiment, the foregoing scheme means that when the number of slaves capable of implementing communication at the second communication rate is determined to be not matched with the total number of slaves in the slave cluster through verification, or if the number is smaller, a rate down adjustment is required based on the second communication rate, and the specific down adjustment ratio is not fixed, and the host may be comprehensively determined according to a preset adjustment value or according to the configuration performance of the slaves. And then repeatedly executing the steps based on the down-regulated communication rate, detecting the slave computer cluster again by using the new communication enhancement frame, obtaining a detection result, and if the detection result still does not reach the standard, continuing to regulate until a communication rate which can be adapted to all the slave computers and meets the requirements of the power line system is found, for example, reducing the communication rate or maximizing the system requirements of the communication rate while meeting the normal communication of all the slave computers. If the number of the slaves passing the verification is the same as the total number of the slaves, the current second communication rate is not the highest rate in the feasible range, and there is an optimization space, and the host can adjust the second communication rate upwards and detect again, especially when the power line system needs to increase the rate, the host in the embodiment can adjust the communication rate upwards in response to the requirement until the maximum communication rate in the feasible range is obtained, so as to meet the requirement of the power line system.
