摘要
海上漏油监测日益重要,但现有的各种方法多用于大型漏油事故的监测。针对水下小型漏油和漏油初期监测,提出利用USB数据线微型USB端的4个针脚作为电极测量阻抗,通过阻抗的突变表明检测到油滴,即实现海水漏油监测。在盐水中测量400次阻抗的标准差为0.058Ω。分别对汽油、柴油、润滑油3种油类和盐水进行区分,从盐水到油中阻抗的变化增量最少为418%,响应时间小于0.19 s。此方法可以实现对海水中漏油的高灵敏、快速监测,未来有着广阔的应用前景。
The monitoring of offshore oil spills is becoming increasingly important, but the various methods available are mostly used in the monitoring of large-scale oil spills. In view of the monitoring of underwater small oil spills and initial oil spills, this paper proposes to use the four pins at the micro USB end of the USB data cable as electrodes to measure the impedance, and the mutation of the impedance indicates the detection of oil droplets, that is, the monitoring of seawater oil spills is realized. The standard deviation for measuring 400 impedances in salt water is 0.058 Ω. The three types of oil(gasoline, diesel and lubricating oil) and salt water were distinguished, and the impedance change from salt water to oil increased by at least 418% and the response time was less than 0.19 seconds. This method can realize the high-sensitive and rapid monitoring of oil spills in seawater, and has a broad application prospect in the future.
