格式化数据方法：

格式化数据方法：
setData(data, deviceTypeMap) {
				let pdids = []
				data.forEach(dev => {
					if (!pdids.includes(dev.ibdr_pdid)) {
						pdids.push(dev.ibdr_pdid)
					}
				})
				pdids = pdids.sort() // 按pdid从小到大排序
				const tempDataList = []
				pdids.forEach(pdid => {
					let title = ''
					const name = deviceTypeMap[pdid]
					if (name) {
						title = pdid + '-' + name
					}
					const item = {
						title: title,
						equipmentList: []
					}
					data.forEach(dev => {
						if (pdid === dev.ibdr_pdid) {
							item.equipmentList.push(dev)
						}
					})
					tempDataList.push(item)
				})
				
				this.typeList = tempDataList
				console.log("this.typeList",JSON.stringify(this.typeList))
			},
