As shown in fig. 1, this embodiment provides a method for intelligent state management and monitoring of a digital receiving module, which includes the following steps:
step S1, establishing voltage and current data acquisition of a PMBUS inside a module;
specifically, voltage and current monitoring data acquisition and enabling management of a power supply rail are completed when the module works through information interaction of the PMBUS power supply management chip and an internal circuit of the digital receiving module;
step S2, carrying out mode distinction on working conditions of the digital receiving module under different power consumption;
specifically, mode distinction is carried out on working conditions under different power consumption and power rail requirements of the digital receiving module, and the mode distinction is marked as an A mode, a B mode, a C mode and the like;
wherein, the A mode is: in the standby mode, only the FPGA (including a communication interface chip) and the PMBUS power management circuit work, and the rest low-noise amplifier and the radio frequency digital-analog sampling circuit do not work. The digital receiving module can receive an external instruction to switch the working modes, and the power consumption is minimum at the moment.
The B mode is as follows: in a static working mode, the FPGA, the PMBUS power management circuit, the low-noise amplifier and the radio frequency digital-analog sampling circuit work, but the FPGA kernel program is in an initialized state, and the power consumption is low.
The C mode is as follows: in a dynamic working mode, the FPGA, the PMBUS power management circuit, the low-noise amplifier and the radio frequency digital-analog sampling circuit work, and the FPGA kernel program is in an operating state, so that the power consumption is maximum.
S3, enabling management of the power rail in various working modes is completed through bus data;
specifically, the PMBUS bus data is used for completing the power rail enabling management under the working conditions of the A mode, the B mode and the C mode; and in a standby mode (the working mode is judged by the FPGA after recording the received upper computer instruction), other circuit power supplies except the FPGA power supply are turned off, so that the standby power consumption is reduced.
S4, recording bus data in each mode and setting acquired data errors;
specifically, the PMBUS bus data under the working conditions of the A mode, the B mode and the C mode are recorded and the acquired data tolerance is set;
the data tolerance setting is set according to the PMBUS bus data and the voltage and current sampling precision in the PMBUS power management circuit under the working conditions of the A mode, the B mode and the C mode.
Specifically, in a certain A system, the fluctuation range of input voltage is +/-5%, the sampling precision of PMBUS power supply management voltage and current is 16 bits, the sampling range of voltage is 0-20V, and the sampling range of current is 0-10A. The voltage of each working condition is 12V (taking the input voltage and current of the power supply as an example), and the working current of the A mode is 1.5A, the working current of the B mode is 4A, and the working current of the C mode is 7A.
The ideal resolution of the circuit current
The circuit voltage ideal resolution
The sampling precision is far greater than the voltage fluctuation and current fluctuation range, and the measurement error introduced by the sampling precision is negligible.
The input voltage fluctuates by +/-5%, the tolerance of the voltage acquisition data is set to +/-8% by considering factors such as fluctuation of the high-low temperature stress of the acquisition data system, namely, the voltage is judged to be normal at 12V +/-8%.
Considering that the voltage fluctuation brings the change of the working efficiency of the power supply and the change of the power supply current in a high-low temperature range, the tolerance of the current collection data is set to be +/-15% of the current data under the rated working voltage, namely the current in the A mode is judged to be normal at 1.5A +/-15%, the current in the B mode is judged to be normal at 4A +/-15%, and the current in the C mode is judged to be normal at 7A +/-15%.

As shown in fig. 3, the intelligent state management monitoring method of the digital receiving module aims at the false alarm correction process flow chart of step S5 under the condition of manual intervention.
After the start, judging a working mode according to a working instruction recorded by the FPGA, when the working mode is in the A mode, reading and recording data of each power rail in the A mode, and setting the tolerance to be 2 times of the acquisition error according to the acquisition error of a PMBUS hardware circuit, specifically, taking a TPS40428 chip as an example, wherein the voltage acquisition precision is +/-0.8% Vout, and the current acquisition precision is +/-640 mA (maximum 50A).
However, due to the influence of some nonlinear parameters of circuit spurious parameters and transient characteristics, the data collected by the PMBUS may be disturbed to generate weak changes, and at this time, false alarms are generated due to insufficient tolerance setting.
And (3) carrying out false alarm correction under the condition of manual intervention, carrying out baking machine test verification on parameters before the step S5, judging whether the false alarm is carried out according to external detection conditions or system working states by manual intervention when reporting the abnormal processing, carrying out tolerance correction according to abnormal data conditions when confirming the false alarm, adjusting down the corresponding data threshold if the return value is too small to compare the false alarm with the abnormal data, and adjusting up the corresponding data threshold if the return value is too large to compare the false alarm with the abnormal data.
As shown in fig. 4, the invention is a software judgment flow chart of final intelligent on-line monitoring,
firstly, determining a current working condition mode according to a command record, then reading according to working condition current and voltage data corrected in the step S5, setting an abnormality judgment standard, specifically, setting the working current of a certain digital receiving module in the working mode A to be 0.25-0.28A, and determining that the current is abnormal when the detected current is out of the range under the working condition.
The on-line judging process is to periodically extract and judge the voltage and current of the PMBUS bus data. The period can be adjusted according to the equipment use requirement and the resource occupation condition.
