本发明涉及移动穿戴设备领域，具体涉及一种基于移动穿戴设备的气密性持续检测泄漏系统及方法。The invention relates to the field of mobile wearable devices, in particular to a system and method for continuously detecting leakage of airtightness based on mobile wearable devices.
背景技术Background technique
随着智能穿戴设备的普及，移动健康监测智能穿戴设备产品(智能手表)对实用性和防水性能要求的提高，防水级别从生活防水提高到专业潜水达到ATM5/ATM10的专业级别防水。设备在出厂检测之后完成判定防水级别。用户在使用1-2年后气密性能出现老化降低防水性能后漏水，使用过程中不知道产品的气密状态产生误以为是防水，实际老化漏水的状态无法得知，导致进水损坏。厂家申明在规定环境中测试否则进水不保修，进水后自己负责。用户在使用过程中设备一旦腔体漏水导致PCBA烧坏产生高昂的维修费用后对产品质量产生怀疑。防水设计通过检测后合格，但在使用环境和温度变化差异不同，气密性的时间周期也会发生变化，无法得知气密性的有效周期和泄漏的时间点。With the popularization of smart wearable devices, mobile health monitoring smart wearable device products (smart watches) have higher requirements for practicality and waterproof performance, and the waterproof level has been raised from daily life waterproof to professional diving to ATM5/ATM10 professional level waterproof. After the equipment is tested at the factory, the waterproof level is determined. After 1-2 years of use, the airtightness of the product deteriorates and the watertightness deteriorates, and then water leaks. The user does not know the airtightness of the product during use and mistakenly thinks it is waterproof. The actual aging and leaking state cannot be known, resulting in water damage. The manufacturer declares that the test should be carried out in the specified environment, otherwise the warranty will not be guaranteed if the water enters, and you will be responsible for it after entering the water. During the use of the equipment, once the cavity leaks and the PCBA is burned out, the user will doubt the product quality after high maintenance costs. The waterproof design is qualified after passing the test, but the time period of airtightness will also change depending on the use environment and temperature changes, and it is impossible to know the effective period of airtightness and the time point of leakage.
现有技术缺点：防水是基于物理结构的生产方法和材料性能可靠性申请专利保护，只是出厂检测合格，就交付质量检测判断出厂，合格就完成产品。使用后期用户无法判断设备的气密性能失效时间。国家标准ATM5、ATM10系列检测标准，出厂后质保时间有限，在加上用户使用环境不同产品的气密周期会各有不同。在消费电子一般质保一年，超过保修范围的进水导致维修费用由客户自己承担，用户在使用过程中无法判断设备的气密性什么时间老化失效，给用户的使用会出现困扰，不同的使用环境下质量稳定周期不同，无法及时维修保养气密性能，在气密性功能损坏的情况浸泡水中导致设备受损的维修麻烦。Disadvantages of the existing technology: Waterproofing is based on the production method of the physical structure and the reliability of the material performance to apply for patent protection. Only the factory inspection is passed, and the delivery quality inspection is judged to leave the factory, and the product is completed after passing the inspection. After use, the user cannot judge the expiration time of the airtight performance of the device. The national standard ATM5 and ATM10 series testing standards have a limited warranty period after leaving the factory, and the airtight cycle of different products in different user environments will be different. In consumer electronics, the general warranty is one year, and the maintenance costs caused by water ingress beyond the scope of the warranty shall be borne by the customer. The user cannot judge when the airtightness of the device will age and fail during use, which will cause trouble for the user. Different uses The quality stability cycle is different in the environment, and the airtight performance cannot be repaired and maintained in time. If the airtight function is damaged, immersion in water will cause trouble in maintenance of equipment damage.

如图2所示，本发明的一种基于移动穿戴设备的气密性持续检测泄漏系统，包括：As shown in Fig. 2, a kind of airtight continuous leak detection system based on mobile wearable device of the present invention includes:
移动穿戴设备，穿戴在人体上，具有气密性持续检测泄漏系统，当跟随人体在运动状态下产生高低落差时，利用气密性持续检测泄漏系统检测设备腔体内外气压值；Mobile wearable equipment, worn on the human body, has an airtight continuous detection leakage system. When following the human body in motion, there is a height difference, and the airtight continuous detection leakage system is used to detect the air pressure inside and outside the equipment cavity;
气密性持续检测泄漏系统，包括采集判断模块，通过采集判断模块对移动穿戴设备在人体移动有高低落差的气压变化时，通过内外气压差的不对等，来判断腔体的气密性；Airtightness continuous detection leakage system, including the acquisition and judgment module, through the acquisition and judgment module, when the mobile wearable device has a height difference in the air pressure change when the human body moves, the air tightness of the cavity is judged by the unequal difference between the internal and external air pressure;
还包括预警模块，与采集判断模块之间通过串口通信连接，用于根据判断的结果记录时间并进行声和/或光和/或震动预警；It also includes an early warning module, which is connected to the acquisition and judgment module through serial port communication, and is used to record time and perform sound and/or light and/or vibration early warning according to the judgment result;

本实施例中，采集判断模块包括主控芯片以及检测元件，所述检测元件为分别布设在移动穿戴设备外部的第一气密性检测传感器1以及布设在移动穿戴设备内部密闭腔室中的第二气密性检测传感器2，利用第一气密检测传感器与第二气密检测传感器在产生高低落差气压变化时识别设备腔体的内外气压差并将检测值传输至主控芯片进行判断。In this embodiment, the acquisition and judgment module includes a main control chip and a detection element, the detection elements are the first air
采集判断模块：输出信号0/1(0代表气密完整；1代表泄漏)系统记录时间，出现信号1就提醒用户此设备出现气密功能失效，请及时维修。Acquisition and judgment module: Output signal 0/1 (0 means complete airtightness; 1 means leak) system records time, when
其中，第一气密性检测传感器与第二气密性检测传感器均采用气压传感器。气压传感器的工作原理：如图1所示，气压传感器主要的传感元件是一个对压强敏感的薄膜，它连接了一个柔性电阻器。当被测气体的压强降低或升高时，这个薄膜变形，该电阻器的阻值将会改变。电阻器的阻值发生变化。从传感元件取得0-5V的信号电压，经过A/D转换由数据采集器接受，然后数据采集器以适当的形式把结果传送给采集判断模块。Wherein, both the first air tightness detection sensor and the second air tightness detection sensor use air pressure sensors. The working principle of the air pressure sensor: As shown in Figure 1, the main sensing element of the air pressure sensor is a pressure-sensitive film, which is connected to a flexible resistor. When the pressure of the gas being measured decreases or increases, the membrane deforms and the resistance of the resistor changes. The resistance value of the resistor changes. The signal voltage of 0-5V is obtained from the sensing element, which is accepted by the data collector through A/D conversion, and then the data collector sends the result to the acquisition and judgment module in an appropriate form.
其中，移动穿戴设备还包括显示屏模组、振动马达以及扬声器模组，比如：移动穿戴设备的声音模组喇叭发出紧急嘟嘟声报警；显示屏模块的红色图案的弹出，电信通讯模块的传输给云端上报记录，震动马达发出震动佩戴者设备的气密状态的通知。Among them, the mobile wearable device also includes a display module, a vibration motor and a speaker module, such as: the sound module speaker of the mobile wearable device emits an emergency beep alarm; the pop-up of the red pattern of the display module, the transmission The record is reported to the cloud, and the vibration motor sends out a notification to vibrate the airtight state of the wearer's device.
本发明在检测时，如图2所示，首先在移动穿戴设备的外部安装第一气密性检测传感器，以及在移动穿戴设备内部密闭腔室中安装第二气密性检测传感器；In the detection of the present invention, as shown in FIG. 2 , first, a first airtightness detection sensor is installed outside the mobile wearable device, and a second airtightness detection sensor is installed in a closed chamber inside the mobile wearable device;
如图4所示，当移动穿戴设备跟随人体在运动场景下并产生气压高低差值时，利用第一气密性检测传感器与第二气密性检测传感器检测移动穿戴设备的内外气压差值，如(走楼梯、深蹲)产生(h值)高低落差1.5米左右产生气压变化识别设备腔体的内外气压值的差值给出结果，监测的顺序是在现有高度落差变化时气压传感同时采集，计算出内外的气压差值。As shown in Figure 4, when the mobile wearable device follows the human body in a sports scene and generates a difference in air pressure, use the first air tightness detection sensor and the second air tightness detection sensor to detect the difference between the internal and external air pressure of the mobile wearable device, For example, (walking stairs, squatting) produces (h value) a height difference of about 1.5 meters, resulting in pressure changes, identifying the difference between the internal and external pressure values of the equipment cavity, and giving the results. The order of monitoring is to sense the air pressure when the existing height difference changes. At the same time, the air pressure difference between the inside and outside is calculated.
将检测得到的内外气压差值利用采集判断模块进行判断，判断逻辑为：当内外气压差值不同时，判定为气密状态完整；当内外气压差值相同或差值减小时，内外气是没有受到阻隔，判定为气密状态为泄露状态；具体的，针对移动的穿戴设备有高低落差时，腔体内外的气压值监测和识别，做出气压差的判断。判断状态1：采集到的气压值A是不等于B，这时采集模块判定为气密状态完整，如图5所示；判断正常状态2：采集到的气压值A是等于B，内外气压是没有收到阻隔，这时采集模块判定为气密状态泄漏状态，如图6所示。The detected internal and external air pressure difference is judged by the acquisition and judgment module. The judgment logic is: when the internal and external air pressure difference is different, it is judged that the airtight state is complete; when the internal and external air pressure difference is the same or the difference decreases, the internal and external air is not If it is blocked, it is determined that the airtight state is a leakage state; specifically, when the mobile wearable device has a height difference, the air pressure value inside and outside the cavity is monitored and identified, and the air pressure difference is judged. Judgment state 1: The collected air pressure value A is not equal to B, and the acquisition module judges that the airtight state is complete, as shown in Figure 5; Judgment normal state 2: The collected air pressure value A is equal to B, and the internal and external air pressure is If no barrier is received, the acquisition module is judged to be airtight and leaking, as shown in Figure 6.
当判定气密状态为泄露状态时，利用串口模块发送消息给预警模块；利用预警模块根据判断的结果记录时间并进行声音、光线以及振动的预警，完成对气密功能的检测与预警；最后将预警信号无线上传至云端上报记录。When it is judged that the airtight state is a leakage state, use the serial port module to send a message to the early warning module; use the early warning module to record the time according to the judgment result and perform early warning of sound, light and vibration to complete the detection and early warning of the airtight function; Early warning signals are wirelessly uploaded to the cloud for reporting records.
本发明的构思在于：在密闭腔体内部和外部放置各放置一个气压传感器，高精度气压传感器在落差超过1米以上的落差时会有气压的值的变化，设备会监测到气密结果，如果腔体出现泄漏现象则内部与外部的气压一致就可以判定是腔体破损，发出提示，系统记录下泄漏时间便于维修处理。The idea of the present invention is to place an air pressure sensor inside and outside the airtight cavity. The high-precision air pressure sensor will change the air pressure value when the drop exceeds 1 meter, and the device will monitor the airtight result. If If the cavity leaks, the internal and external air pressures are the same, it can be judged that the cavity is damaged, a reminder will be issued, and the system will record the leakage time for easy maintenance.
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何不经过创造性劳动想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求书所限定的保护范围为准。The above is only a specific implementation of the present invention, but the scope of protection of the present invention is not limited thereto, and any changes or replacements that do not come to mind through creative work shall be covered within the scope of protection of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope defined in the claims.
