具体实施方式
为更进一步阐述本实用新型为达成上述目的所采取的技术手段及功效，以下结合附图及较佳实施例，对本实用新型的具体实施方式、结构、特征及其功效进行详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本实用新型，并不用于限定本实用新型。
如图1所示，图1是本实用新型用于检测食用肉新鲜度的便携式设备优选实施例的外部结构示意图。在本实施例中，所述用于检测食用肉新鲜度的便携式设备包括设备本体10以及连接在设备本体10上的第一探针4和第二探针5。所述设备本体10包括键盘7、显示屏8以及USB接口9。所述键盘7和显示屏8安装在靠近第一探针4的设备本体10一端的上表面，所述USB接口9安装在靠近第一探针4的设备本体10一端的侧面，也可安装在设备本体10的其他位置。
所述设备本体10采用硬质的无毒塑料材质或者轻质的不锈金属材质（例如，金属铝、不锈钢等）制作，使用者可以单手握住设备本体10的中间部位对食用肉20的新鲜程度进行检测操作。所述第一探针4和第二探针5均为导电的电极探针，其外部包裹有绝缘材料。当需要检测食用肉20的新鲜程度时，所述第一探针4和第二探针5分别用于与待测的食用肉20接触（即分别将第一探针4和第二探针5插入食用肉20内）。所述键盘7包括多个控制键和一个电源开关键，所述控制键用于控制食用肉20新鲜程度的检测过程，所述电源开关键用于开启或关闭用于检测食用肉新鲜度的便携式设备，以便对食用肉20的新鲜程度进行检测。所述USB接口9可以作为将检测数据（例如食用肉20的新鲜程度的信息等数据）传输至外部设备的数据传输接口，也可以作为所述便携式设备内部电源的充电接口。
本领域可以理解的是，交变电流能够连续地通过生物组织，通过生物组织的有效交变电流量可以用阻抗值（Z）来描述。在本实施例中，所述食用肉20的脂质细胞膜具有一定的阻抗，能够传导交变的电流信号，因此本实用新型所述用于检测食用肉新鲜度的便携式设备通过测量食用肉20的阻抗值就可以检测所述食用肉20的新鲜程度。
如图2所示，图2是本实用新型用于检测食用肉新鲜度的便携式设备的设备本体优选实施例的内部结构示意图。在本实施例中，所述设备本体10的内部还包括微控制器1、数模转换器2、压控振荡器3以及振幅衰减检测器6。所述数模转换器2的输入端连接至微控制器1上，输出端连接至压控振荡器3的输入端。所述压控振荡器3的一个输出端连接至第一探针4上，另一输出端连接至振幅衰减检测器6的一个输入端，该振幅衰减检测器6的另一输入端连接至所述第二探针5上，该振幅衰减检测器6的输出端连接至所述微控制器1上。所述键盘7、显示屏8和USB接口9均连接至所述微控制器1上。
在本实施例中，所述微控制器1可以为一种微处理器、微控制单元（MCU）、信号处理芯片、或者具有信号控制功能的信号控制单元。当需要检测食用肉20的新鲜程度时，使用者将第一探针4和第二探针5分别与食用肉20接触（即分别将第一探针4和第二探针5插入食用肉20上），并开启键盘7上的电源开关键。所述微控制器1产生并发送检测信号至数模转换器2上，该数模转换器2将所述检测信号转换为模拟电平信号，并将模拟电平信号发送至所述压控振荡器3上。
所述压控振荡器3全称为电压控制振荡器，通常由VCO(Voltage Controlled Oscillator)表示，它是一种将电平变换为相应频率的脉冲变换电路，或者说是输出脉冲频率与输入信号电平成比例的电路，被广泛应用在自动控制、自动测量与检测等技术领域。在本实施例中，所述压控振荡器3用于根据所述模拟电平信号产生激励电信号，并将所述激励电信号通过第一探针20发送至待测的食用肉20上。
所述第二探针5从所述食用肉20中检测所述激励电信号经过该食用肉20后的反馈电信号，并将获取的反馈电信号发送至振幅衰减检测器6上。
所述振幅衰减检测器6是一种具有检测和分析信号振幅衰减程度的处理器，被广泛应用在阻抗检测等技术领域。在本实施例中，所述振幅衰减检测器6用于接收压控振荡器3产生的激励电信号以及第二探针5检测到的反馈电信号，并根据所述激励电信号和反馈电信号分析出食用肉20的阻抗值。
所述微控制器1用于根据所述食用肉20的阻抗值分析出所述食用肉20的新鲜程度。具体地，所述微控制器1判断所述食用肉20的阻抗值是否小于预设范围。本领域可以理解的是，新鲜肉的细胞膜具有阻抗具有电流传递特性，而变质肉（例如过期的肉或煮过的肉）的细胞膜被破坏，相应的电流传输能力将增强，体现在阻抗上就是阻抗的降低。肉类细胞膜的阻抗随着交变电流的频率增加而降低。随着肉类纤维细胞膜的老化，相应的阻抗也会发生变化，通常来讲新鲜肉类的阻抗值在340-540ohms之间，这个阻抗值随着肉类随着存储时间的增长而降低。本实施例中，本实施例中，所述预设范围定义为340ohms至540ohms之间，其中，ohms为阻抗值的单位。由于新鲜肉类的阻抗值一般在340 ohms至540ohms之间，因此，如果食用肉20变质，该食用肉20的阻抗值只能小于340 ohms，而不会大于540ohms。
当所述食用肉20的阻抗值小于预设范围（即小于340 ohms）时，所述微控制器1产生一条食用肉为变质肉的信息（即表明该食用肉20的新鲜程度较低），并控制显示屏7显示所述食用肉为变质肉的信息。当所述食用肉20的阻抗值介于预设范围时，产生一条食用肉为新鲜肉的信息（即表明该食用肉20的新鲜程度较高），并控制显示屏7显示所述食用肉为新鲜肉的信息。
在本实施例中，所述键盘7、显示屏8和USB接口9均连接至所述微控制器1上。所述键盘7包括多个控制键和一个电源开关键，所述控制键用于控制食用肉20新鲜程度的检测过程。所述显示屏8用于显示所述激励电信号和反馈电信号的波形以及显示食用肉20的新鲜程度。所述USB接口9用于将检测数据传输至外部设备或者用于为所述用于检测食用肉新鲜度的便携式设备内部电源进行充电。
在本实施例中，所述微控制器1也可以通过所述USB接口9或者其它通信接口将食用肉20的检测数据传输至质检部门的外部设备，以供质检人员对食用肉20进行食品安全检查。
以上仅为本实用新型的优选实施例，并非因此限制本实用新型的专利范围，凡是利用本实用新型说明书及附图内容所作的等效结构或等效功能变换，或直接或间接运用在其他相关的技术领域，均同理包括在本实用新型的专利保护范围内。
