背景技术
目前，随着人民生活水平的提高，人们对工作环境的热表面接触提出了更高的要求，即对劳动过程中的人体进行保护。
例如，人体在操作某些发热设备时，表面温度会影响工人作业效率和作业安全。为了以防人在接触热产品表面时发生灼伤，必须规定相关接触表面温度极限值。如何选择合理的接触表面温度极限值是非常重要，不同的工作任务下，与发热表面接触时间也不一样。另外对于工作区域内一些高温物体，虽然不需要用手直接接触去操作，但是无意间的触碰也会造成烫伤，因此对于工作区域内可能触碰到的高温物体表面温度也需要进行限定，以保证作业人员工作和安全。运行时是热的又易于接触到的机械表面是烧伤风险源。接触该热表面，可能是有意识发生的，例如操纵机器手柄；也可能是机器旁边的人员无意识所为。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。
在本发明的描述中，术语“纵向”、“横向”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明而不是要求本发明必须以特定的方位构造和操作，因此不能理解为对本发明的限制。本发明中使用的术语“相连”、“连接”、“设置”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接；可以是直接相连，也可以通过中间部件间接相连；可以是有线电连接、无线电连接，也可以是无线通信信号连接，对于本领域的普通技术人员而言，可以根据具体情况理解上述术语的具体含义。
参见图1～3，本发明实施例提供了一种测试皮肤表面接触高温物体反应的试验装置，其包括：加热设备和接触件4。
其中，加热设备用于提供热量，其可以是将电能转变成热能，此时加热设备的加热方式为电加热；还可以是将化学能转变成热能，此时加热设备的加热方式为燃料燃烧加热，本实施例对此不进行限定。接触件4用于传导加热设备的能量以使得可以用接触件4的温度表征高温物体的温度，应用时，可以是两者的温度相同或者两者的温度在误差范围内。接触件4设置于加热设备上，与待测试皮肤表面接触，还与加热设备的加热表面相对，接触件4的材质为高温物体的材质，从而使得可以用接触件4表征高温物体。物体因 工作或受热会使得其自身温度升高，当自身温度高于温度阈值时，则将该物体称之为高温物体，温度阈值可以是室温，还可以是(室温+5℃)，或者其他值。
通过设置加热设备和接触件4，接触件4的材质为高温物体的材质，接触件4的温度为高温物体的温度，进而使得用接触件4可以表征高温物体，便于测试人体皮肤在接触高温物体时的反应，从而可以为实际生产或生活操作过程中会接触到热表面的人机工效学提供试验数据，能进一步的保护劳动者(即生产或生活操作的执行者)。
试验时，通过皮肤与接触件4接触，可以测试不同温度、不同测试方法下人体皮肤接触热表面的时间阈值，接触热表面则主要是烫伤阈值，从而为评估热表面引起的烧伤风险提供数据，为热表面温度和时长在人机交互过程中的影响研究工作提供支持。
为了使加热设备的结构简单和能较精准地控制接触件4的温度，加热设备包括：箱体1、电加热体、加热控制器和温度输入单元。箱体1用于提供支撑和容纳空间，其形状可为长方体。电加热体用于将电能转变为热能，其一端置于箱体1外，与接触件4相对，另一端置于箱体1上或箱体1内。加热控制器与电加热体连接，用于控制电加热体的加热过程以使经电加热体加热后接触件4的温度达到预设温度，其所用加热方式可以是现有技术中的PID控制方法，也可以是其他控制方法。温度输入单元与加热控制器连接，用于输入预设温度，其可以设置在箱体1上。温度输入单元的表现形式可以是按钮，还可以是旋钮2，又可以是触摸显示屏。为了便于试验人员及时掌握当前预设温度，本加热设备还包括：第一显示单元3，与加热控制器连接，用于显示预设温度。
实际工作中，与高温物体的接触方法(或称测试方法)通常有抓握方法，如用手掌抓握，还有触碰方法，如用手指或其他皮肤部位触碰，为了使本试验装置能适应不同的接触方法，接触件4呈筒状，并套设于电加热体的一端外，接触件4的底端延伸至箱体1的表面。接触件4的上端为封口状，如此利于电加热体的热量较多的传导给接触件4，在较短时间内实现接触件4的温度与预设温度一致。可以将接触件4和电加热体合成为温度接触测量棒9。接触件4的直径范围为25-35mm，如25cm、26cm、27cm、28cm、29cm、30cm、 31cm、32cm、33cm、34cm、35cm，可以利于人体手抓握接触件4。接触件的横截面优选呈圆形。
为了提高传热效率，接触件4与电加热体的周向表面和顶面接触，即接触件4套接于电加热体外且接触件4的内端面与电加热体的顶面接触。在电加热体和接触件4之间粘接有导热硅胶，使得两者可以很好的接触，在提高导热性能的同时，还能稳定地将接触件4固定在电加热体上。电加热体为电加热棒5。
当用手抓握时，手掌与接触件4的接触面积较大，若接触件4表面温度一致性较差，则不能很好地完成试验工作，为了提高接触件表面温度一致性，可以通过改变接触件4径向方向上的厚度和轴向方向上的厚度来实现，通常电加热体顶端由于受电加热体结构影响，尤其当电加热体为电加热棒时，散热面积较大，因此接触件4轴向方向上的厚度小于其径向方向上的厚度，即接触件4的顶端厚度小于接触件4的侧壁厚度。接触件4的具体尺寸会因接触件4材质的不同而异，其可以通过表面温度一致性的标定测试来确定。表面温度一致性的标定主要是针对接触件4表面各个方向进行表面温度测量，如果各测点温差超过误差限值，则通过改变接触件4各方向的壁厚来调节。
为了便于控制试验开始时间，本试验装置还包括：测点传感器7和第二显示单元6。测点传感器7用于测量接触件4的温度，其设置于接触件4内，如镶嵌。第二显示单元6与测点传感器4连接，用于显示测点传感器4测试的温度。测点传感器7的温度数据可由导线8沿接触件4内部输入给设置在箱体1上的第二显示单元6。当第二显示单元6显示的温度与预设温度一致时，便可以开始测试。由于测试时皮肤部位接触接触件4后会造成接触件4表面温度的下降，因此测试时也要记录皮肤部位与接触件4表面接触后的温度，该温度为显示温度，可以通过第二显示单元6观察并记录。在其他的实施例中，测点传感器7可以与电加热器连接。加热控制器可以根据测点传感器7测量的温度对电加热体的加热过程进行控制。测点传感器7还可以通过加热控制器与第二显示单元6连接。
受接触件4外环境空气温度影响，测点传感器7通常不会布置在接触件4的外表面，而是布置在接触件4内部。为了使第二显示单元6显示的温度与接触件4的表面温度一致，即两者的差值符合误差要求，需调整测点传感 器7在接触件4内的埋入深度，该深度是相对于接触件4径向外表面的深度。该深度可以通过显示温度与实际温度(即接触件的实际温度)偏差标定测试来确定。标定时，温度可采用红外热线仪进行测量。
实际的生产或生活中，皮肤部位可能会接触高温物体，还可能会接触低温物体，为了得到全面的试验数据，即得到皮肤部位接触冷表面后的数据，本试验装置还包括：低温环境室，其用于提供低温环境，低温环境的温度通常低于室温，具体可以根据试验要求确定。应用时，将加热设备和接触件4置于低温环境室内，此时加热设备不工作，达到一定时间后，进行测试。此时，通过皮肤与接触件4接触，可以测试不同温度、不同测试方法下人体皮肤接触冷表面的时间阈值，接触冷表面包括疼痛、麻木、冻伤等阈值。
高温物体的材质会不同，不同材质在相同温度下接触热感觉不同，为了提高试验效率，本试验装置的加热设备的数量为多个，接触件4的数量也为多个，多个接触件4的材质互不相同，多个接触件4与多个加热设备一一对应，以使得每个接触件4有独立的加热设备，从而可以一次性测试多种材质。加热设备数量的多少可根据具体的试验需求来确定。需要注意的是：不同材质的接触件4之间的间距也应符合人手抓握时的尺寸，不应相互干涉，如间距大于15cm。
由技术常识可知，本发明可以通过其它的不脱离其精神实质或必要特征的实施方案来实现。因此，上述公开的实施方案，就各方面而言，都只是举例说明，并不是仅有的。所有在本发明范围内或在等同于本发明的范围内的改变均被本发明包含。
