Detailed Description
For a further understanding of the present invention, reference is made to the following detailed description taken in conjunction with the accompanying drawings and examples.
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly and may include, for example, a fixed connection, an integral connection, and a detachable connection; either mechanically or electrically, or internally communicating two elements; they may be directly connected or indirectly connected through an intermediate, and those skilled in the art will understand the specific meanings of the above terms according to specific situations.
Example 1
With reference to fig. 1, the technical scheme of the invention is a charging pile disaster recovery charging method, which comprises the following steps:
acquiring the same input signal;
respectively carrying out independent signal processing on the input signals to respectively obtain signal processing results;
voting is carried out on all the signal processing results, and execution signals are output according to the voting distribution results;
and executing a charging action according to the execution signal.
In the above embodiment, the object for acquiring the input signal is each control mainboard arranged in the charging pile, and each control mainboard performs operation processing on the same input signal to obtain a corresponding signal processing result; each control mainboard which finishes the operation shares the signal processing result to other control mainboards; each control main board can obtain the signal processing results of all the control main boards, and each control main board votes for all the signal processing results to obtain the voting distribution result.
In the above embodiment, the signal processing result is an instruction for controlling the main board to perform an action on a certain switch, for example, an on/off action of a relay on a certain power output loop.
In the above embodiment, under normal conditions, the results of processing the same input signal by all the control main boards are consistent; however, if the hardware is aged or affected by strong magnetic interference, different control mainboards can output different signal processing results; for example, the signal processing result of one control mainboard is that the relay is powered on, and the signal processing results of the other control mainboards are that the relay is powered off. After the operation results are shared among the control main boards, each control main board votes according to the power-on or power-off instruction, a uniform voting distribution result can be obtained, at the moment, high and low sequencing is carried out according to the ticket obtaining rate or the ticket obtaining number of the signal processing result, and the signal processing result with the high ticket obtaining rate or the high ticket obtaining number is used as a final execution signal.
In this embodiment, a first main body is determined from the distribution result of the votes, the signal processing result of the first main body coincides with the signal processing result corresponding to the highest voting rate in the distribution result of the votes, and the execution signal is output by the first main body.
In the above embodiment, the control main board consistent with the signal processing result with the high ticket obtaining rate or the high ticket obtaining number is used as the first main body, and the final execution signal is sent by the control main board; in another embodiment, the final execution signal may be sent by a control main board other than the first main body.

For example, the control boards numbered 2 and 3 are both the first body, and the control boards numbered 2 and 3 confirm that the control board numbered 1 is not the first body by sharing the operation result, and then the control board numbered 2 undertakes the task of sending the execution signal according to the arrangement sequence.
In this embodiment, when there are at least two kinds of signal processing results in the distribution result of the votes, a second main body is determined according to the distribution result of the votes, and the signal processing result of the second main body coincides with the signal processing result corresponding to the lowest voting rate in the distribution result of the votes.
In the above embodiment, in the process of executing a charging action, only when different signal processing results are generated between the control motherboards, the second main body can be determined; in other words, the control board listed as the second body is a control board whose signal processing result is abnormal.
In this embodiment, the charging action, the execution signal, the distribution result of the corresponding votes, and the input signal constitute a charging response event, and the charging response event is reported and stored.
In the above embodiment, the charging response events sent by the charging pile are uploaded to the cloud server for storage and recording, the uploading main body may be a control main board sending an execution signal, and event transmission is completed through a communication module arranged in the charging pile.
In this embodiment, when the number of times listed as the second subject in the charging response event exceeds a preset threshold, the charging pile in which the charging response event occurs is marked.
In the embodiment, when the number of times that one charging pile is listed as the second main body is too many, the charging pile is marked, and the cloud server reminds operators of overhauling through an alarm mode.
In the above embodiment, the preset threshold may be the total number of times that one charging pile is listed as the second main body, or the number of times that one control main board in one charging pile is listed as the second main body.
In this embodiment, the input signal is at least one of a power signal, a current signal and a voltage signal.
In this embodiment, the execution signal is a switch switching signal, and the switch switching signal has only two states, i.e., on and off.
In the above embodiment, the charging pile disaster recovery charging method mainly aims at the decision that the influence on the charging of the automobile is large, and for some signal processing with small influence on the charging of the automobile, a single control mainboard processing mode is adopted, such as an indicator light, charging information display and the like.
In the above embodiment, when a single control motherboard processes, other control motherboards may be in a sleep state; when a signal which needs to be voted for decision output is acquired, the control mainboard in the dormant state is awakened by the signal, and the specific awakening mode can be awakened by the single board which is always in the working state, or an awakening circuit is arranged to awaken the control mainboard in the dormant state when the control mainboard receives power, voltage and current signals.
According to the technical scheme, the number of the control main boards is increased in the charging system of the charging pile, each control main board independently processes key input signals, each control main board sends the signal processing result of the control main board to other control main boards for result sharing, namely, each control main board can obtain the signal processing results of all the control main boards, all the signal processing results are voted to obtain the voting distribution results, so that correct execution signals are obtained, and any control main board sends the execution signals to the output module to execute charging actions.
