背景技术Background technique
传统的气压测量装置一般采用机械式气压表直接测量或者单一的传感器测量，由人工现场读数完成数据采集，机械式气压表测量虽然简单，但需要花费大量劳动力且实时性较差，在数据采集过程中还容易出现人为错误；当现场有大量的气压（如气囊船舶下水施工技术中有大量的气囊）需要测量时，每读完一次所有气压数据需要大量的时间。而基于ZigBee网络模式的无线气压传感器网络则可测量多个测量点的气压并通过ZigBee协调器将各气压点的气压数据收集在一起，再通过PC界面显示，也可以通过网络协议转换器将其送入云端并通过手机、平板电脑等查看气压数据。Traditional air pressure measurement devices generally use mechanical barometers for direct measurement or single sensor measurement, and data collection is completed by manual on-site readings. Although mechanical barometer measurement is simple, it requires a lot of labor and has poor real-time performance. During the data collection process It is also prone to human error; when there are a large number of air pressures on site (such as a large number of air bags in the air bag ship launching construction technology) to be measured, it takes a lot of time to read all the air pressure data once. The wireless air pressure sensor network based on the ZigBee network mode can measure the air pressure of multiple measurement points and collect the air pressure data of each air pressure point through the ZigBee coordinator, and then display it through the PC interface, or transfer it through the network protocol converter. Send to the cloud and view barometric pressure data through mobile phones, tablets, etc.
ZigBee技术是一种新兴的近距离、低复杂度、低功耗、低数据速率、低成本的无线网络技术。在要求数据采集或监控的网点多、传输数据量不大但设备成本低、数据传输安全性高、设备体积小、地形复杂需要较大的网络覆盖等条件下，ZigBee技术可以充分发挥它的优势。而且ZigBee联盟制定了一个全球开放的标准，适用于设计可靠的、成本效益型、低功耗无线网络监测及其控制产品。ZigBee technology is an emerging wireless network technology with short distance, low complexity, low power consumption, low data rate and low cost. ZigBee technology can give full play to its advantages when there are many network points required for data collection or monitoring, the amount of transmitted data is not large but the equipment cost is low, the data transmission security is high, the equipment is small, and the terrain is complex and requires large network coverage. . Moreover, the ZigBee Alliance has developed a global open standard for designing reliable, cost-effective, low-power wireless network monitoring and control products.
ZigBee技术组成的无线传感网络为中短距离、低速率无线传感器网络。射频传输成本低，各节点只需要很少的能量；功耗低，适于电池长期供电；可实现一点对多点，两点间对等通信；具有快速组网自动配置、自动恢复功能；任意个传感器之间可相互协调实现数据通信。可适用于工业控制、现代化农业监控、数字家庭、智能楼宇监控、环境监测等领域。The wireless sensor network composed of ZigBee technology is a short-range and low-speed wireless sensor network. The cost of radio frequency transmission is low, and each node requires only a small amount of energy; low power consumption, suitable for long-term battery power supply; one-to-multipoint, peer-to-peer communication between two points; fast networking automatic configuration, automatic recovery functions; any The sensors can coordinate with each other to realize data communication. It can be applied to industrial control, modern agricultural monitoring, digital home, intelligent building monitoring, environmental monitoring and other fields.
基于ZigBee网络的气压传感器由锂离子电池驱动。由于电池容量有限，一次充电传感器只能工作有限的时间，故现有传感器在使用现场由于电池续航能力差，存在需频繁拆装传感器以更换充电电池的麻烦。随着无线充电技术的不断发展和日趋成熟，传统工业检测技术传感器节点电源的续航能力有限这一问题也迎刃而解。无线充电技术是指具有电池的装置通过电磁感应等无线方式取得电力而进行充电。无线充电技术的出现，一是为了解决在现有电池技术跟不上电子产品发展的情况下，使用户得到相对方便快捷的充电需求；二是可以将现有不统一的电子产品电源接口进行统一，解决充电设备通用性的问题；三是无线充电不需要外接充电接口，从而解决电子产品浸水问题，还可以防止灰尘进入电子产品。The barometric pressure sensor based on ZigBee network is driven by Li-ion battery. Due to the limited battery capacity, a charging sensor can only work for a limited time. Therefore, due to the poor battery life of the existing sensor in the field of use, there is a trouble of frequent disassembly and assembly of the sensor to replace the rechargeable battery. With the continuous development and maturity of wireless charging technology, the problem of limited endurance of sensor node power supply in traditional industrial detection technology has also been solved. Wireless charging technology means that a device with a battery obtains power through wireless means such as electromagnetic induction for charging. The emergence of wireless charging technology, one is to solve the situation that the existing battery technology can not keep up with the development of electronic products, so that users can obtain relatively convenient and fast charging needs; the other is to unify the existing non-uniform power interfaces of electronic products , to solve the problem of versatility of charging equipment; third, wireless charging does not require an external charging interface, thereby solving the problem of electronic products being immersed in water, and can also prevent dust from entering electronic products.
