首先，可以考虑将常量定义为宏，这样可以减少代码量，并且提高代码可读性。例如：

#define NEC_0 19
#define NEC_1 60
#define IR_CODE 167

然后，可以考虑将 send 函数拆分为多个小函数，这样可以提高代码的可维护性。例如：

void send_bit(unsigned char bit) {
if (bit) {
Send_NEC_1();
} else {
Send_NEC_0();
}
}

void send_data(unsigned char data) {
for (unsigned char i = 0; i < 12; i++) {
send_bit(data & 0x01);
data >>= 1;
}
}

void send(unsigned char s1, unsigned char s2) {
Send_NEC_1();
Send_NEC_0();
Send_NEC_1();
Send_NEC_1();

Send_NEC_0();
Send_NEC_0();
Send_NEC_1();
Send_NEC_0();

Send_NEC_0();
Send_NEC_1();
Send_NEC_0();
Send_NEC_0();

Send_NEC_1();
Send_NEC_1();
Send_NEC_0();
Send_NEC_1();

send_data(s1);
Send_NEC_0();
Send_NEC_0();
Send_NEC_0();
Send_NEC_0();

send_data(s2);

Send_NEC_1();
Send_NEC_1();
Send_NEC_1();
Send_NEC_1();
}

最后，可以考虑将 Send1 函数拆分为多个小函数，这样可以提高代码的可读性和可维护性。例如：

void send_repeat() {
Send_IR(IR_CODE);
NotSend_IR(IR_CODE);
Send_IR(IR_CODE);
}

void send_finish() {
Send_NEC_1();
Send_NEC_1();
Send_NEC_0();
Send_NEC_1();

Send_NEC_0();
Send_NEC_1();
Send_NEC_0();
Send_NEC_1();

Send_NEC_0();
Send_NEC_1();
Send_NEC_1();
Send_NEC_0();

Send_NEC_0();
Send_NEC_1();
Send_NEC_1();
Send_NEC_0();

Send_NEC_0();
Send_NEC_0();
Send_NEC_0();
Send_NEC_0();

Send_NEC_0();
Send_NEC_0();
Send_NEC_0();
Send_NEC_0();

Send_NEC_0();
Send_NEC_0();
Send_NEC_0();
Send_NEC_0();

Send_NEC_0();
Send_NEC_0();
Send_NEC_0();
Send_NEC_0();

Send_NEC_0();
Send_NEC_0();
Send_NEC_0();
Send_NEC_0();

Send_NEC_0();
Send_NEC_0();
Send_NEC_0();
Send_NEC_0();

Send_NEC_0();
Send_NEC_0();
Send_NEC_0();
Send_NEC_0();

Send_NEC_0();
Send_NEC_0();
Send_NEC_0();
Send_NEC_0();

Send_NEC_0();
Send_NEC_0();
Send_NEC_0();
Send_NEC_0();
}

void Send1(unsigned char s1, unsigned char s2) {
send_repeat();
send(s1, s2);
send_repeat();
send(s1, s2);
send_repeat();
send_finish();
}
