It with wired compares mainly has the cost to be low, carries conveniently, omits the wired wiring the worry; Specially is suitable to grasping the equipment the correspondence, the battery power supply equipment, the vehicles monitoring, the remote control, the telemetering, the small wireless network, wireless copies the table, the system, the plot messenger call, the industry data acquisition system, the wireless label, the status recognition, must contacts the RF smart card, the small wireless data terminal, the safe fire protection is systematic, wireless domain and so on in external guidance system, biological signal gathering, hydrometeorology monitoring, robot control, digital audio frequency, numeral image transmission the low power loss, the microminiaturization is the current wireless correspondence product then takes along the product in particular the urgent need and the key question.

它与有线相比主要有成本低，携带方便，省去有线布线的烦恼；特别适用于手持设备的通信、电池供电设备、车辆监控、遥控、遥测、小型无线网络、无线抄表、门禁系统、小区传呼、工业数据采集系统、无线标签、身份识别、非接触RF智能卡、小型无线数据终端、安全防火系统、无线遥控系统、生物信号采集、水文气象监控、机器人控制、数字音频、数字图像传输等领域中。低功耗、微型化是当前无线通信产品尤其是便携产品的迫切要求和关键问题。无线通信的另一个关键问题是数据传输的可靠性，这取决于诸多因素，如频率选择、同频干扰、传输距离、天线选择等，这些在设计无线通信系统时都要认真考虑和比较。

Of course, if we find that the local node in the wireless LAN equipment has been illegal attacker encryption, they can not normally enter the local wireless LAN, we can force the wireless device node parameter setting back to default, to restore the specific ways to view the corresponding wireless node equipment manuals, usually as long as we press the wireless node equipment in the control panel button to complete the reset function to restore the task parameters.

当然，要是我们发现本地无线局域网中的节点设备已经被非法攻击者加密，自己不能正常进入本地无线局域网时，我们可以强行将无线节点设备的参数设置恢复到默认状态，具体恢复方法可以查看对应无线节点设备的操作说明书，通常情况下我们只要按下无线节点设备控制面板中的reset功能按钮来完成参数设置恢复任务。

Steering by automatic pilot and by magnetic compass in stead of automatic pilot, Measure the exactness of magnetic compass by qualified calibrator and provide compass adjustment card.

自动驾驶仪操舵和用磁罗经代替自动驾驶仪，通过合格的校准器来测定罗经的正确功能并提供罗经校正卡。

A simple dry magnetic pocket compassA compass, magnetic compass or mariner's compass is a navigational instrument for determining direction relative to the earth's magnetic poles.

Fluxgate sensor inducts the environment magnetic field, outputs the compass course signal to the CPU system. This signal then is transformed into digital signal. CPU processes it and then gains compass course. When use rotary mathod to measure the deviations, CPU first collects timed the compass course come from the Fluxgate sensor, then calculates automatically their deviations and the correspondent coefficients. Based on all this, CPU can calculates out the real-time magnetic course or the real-time ture course, then sents them to display on the digital displayer.

本系统采用磁通门传感器来直接敏感合成磁场，输出罗航向直流感应电压信号送A/D转换器进行转换，并经CPU计算处理得到罗航向度数值，以及利用&旋回法&测定自差时，CPU按照船舶旋回的角速度定时地采集罗航向度数值，在此基础上CPU自动地计算出各采集罗航向上的白差，再由此计算出自差系数，并实时地解算出磁航向值或真航向值，送数码显示器显示。

The objectives of this study were to develop a wireless sensor network technologies for agrometeorological disaster early alarm system and processing system. In this study, the foehn with a high temperature and low humidity has been monitored. The wireless sensor acquisition module ZigBee has been used to monitor the climate conditions combined with a GPRS wireless transmission module to construct wireless disaster alarm sytem. Graphical programming computer software package LabVIEW 8.2 was used to develop the control and monitoring systems.
