位域结构体定义故障位

[ROOF150823]

项目中有57个故障要处理，在故障模块中定义了位域结构体来管理故障位，因为用的是32位单片机，最长无符号整型只用到uint32_t，就设计了两个位域结构体来处理57个故障，用底32位和高32位来区分，代码如下，请教各路大神，有没有更好的设计方法？

typedef union
{
	struct
		{
			uint32_t hpc_com_err    		:1;
            uint32_t coresen_com_err        :1;
            uint32_t fan_com_err            :1;
			uint32_t freq_fault				:1;
			uint32_t hi_refg_pres			:1;
			uint32_t hi_temp_cmpdis			:1;
			uint32_t pres_trans_err			:1;
			uint32_t inwat_sens_err			:1;
			uint32_t outwat_sens_err		:1;
			uint32_t distemp_err    		:1;
			uint32_t suctemp_sens_err		:1;
			uint32_t evap1_coiltemp_err		:1;
			uint32_t evap2_coiltemp_err		:1;
			uint32_t evap1_temp_err			:1;
			uint32_t evap2_temp_err			:1;
			uint32_t lo_refg_pres			:1;
			uint32_t hi_wat_temp			:1;
			uint32_t ambient_temp_err		:1;
			uint32_t rsrv					:14;
			
		}LoFaultBit;
	
		uint32_t all;

	

}LoFaultFlag;

typedef union
{
	struct
	{
		uint32_t rsrv					:32;

	}HiFaultBit;
	
	uint32_t all;

}HiFaultFlag;

typedef struct
{
	LoFaultFlag lofaults;
	HiFaultFlag hifaults;
	
}FaultBits;
