61850协议 相关代码程序

61850协议是一种用于通信和控制的标准化协议，主要用于电力系统自动化领域。以下是一些相关的代码程序：

1. 61850-9-2采样值传输协议的解析程序

#include <stdint.h>

#define SAMPLES_PER_SEC 10

struct SampledValueHeader
{
    uint16_t confRev;
    uint16_t dataSet;
    uint8_t sampledValues[256];
};

void parseSampledValue(const uint8_t* data, size_t len, SampledValueHeader* header)
{
    // Parse header
    header->confRev = (data[0] << 8) | data[1];
    header->dataSet = (data[2] << 8) | data[3];

    // Parse sampled values
    const uint8_t* valuesData = data + sizeof(SampledValueHeader);
    size_t valuesLen = len - sizeof(SampledValueHeader);
    for (size_t i = 0; i < valuesLen; i += 2)
    {
        header->sampledValues[i / 2] = (valuesData[i] << 8) | valuesData[i + 1];
    }
}

2. 61850-8-1报文传输协议的编解码程序

#include <stdint.h>
#include <string.h>

#define MAX_APDU_SIZE 1024

enum ApduType
{
    CONFIRMED_REQUEST = 0x00,
    CONFIRMED_RESPONSE = 0x01,
    UNCONFIRMED = 0x02,
    REQUEST = 0x03,
    RESPONSE = 0x04,
    ERROR = 0x05
};

struct ApduHeader
{
    uint32_t len;
    uint8_t type;
    uint8_t service;
    uint16_t invokeId;
    uint32_t errorCode;
};

size_t encodeApdu(const ApduHeader* header, const uint8_t* data, size_t dataLen, uint8_t* buf, size_t bufSize)
{
    if (bufSize < sizeof(ApduHeader) + dataLen)
    {
        return 0;
    }

    memcpy(buf, header, sizeof(ApduHeader));
    memcpy(buf + sizeof(ApduHeader), data, dataLen);

    header->len = sizeof(ApduHeader) + dataLen;

    return header->len;
}

size_t decodeApdu(const uint8_t* buf, size_t bufSize, ApduHeader* header, uint8_t** data)
{
    if (bufSize < sizeof(ApduHeader))
    {
        return 0;
    }

    memcpy(header, buf, sizeof(ApduHeader));

    if (header->len > MAX_APDU_SIZE)
    {
        return 0;
    }

    if (header->len > sizeof(ApduHeader))
    {
        *data = new uint8_t[header->len - sizeof(ApduHeader)];
        memcpy(*data, buf + sizeof(ApduHeader), header->len - sizeof(ApduHeader));
    }
    else
    {
        *data = nullptr;
    }

    return header->len;
}

以上代码仅供参考，实际应用中需要根据具体需求进行修改。
