Abstract
The utility model discloses a drunk driving alarm system, which comprises alcohol sensors, a signal amplification circuit, a relay switch and an ignition circuit, wherein a normally-closed switch is arranged on the ignition circuit; the alcohol sensors are connected with the normally-closed switch on the ignition circuit after passing through the signal amplification circuit and the relay switch; the drunk driving alarm system further comprises an alarm and an alcohol testing instrument; the alarm is respectively connected with the relay switch and the alcohol testing instrument; and a respirator is connected to the alcohol testing instrument through a hose. According to the drunk driving alarm system, the alcohol sensors, the signal amplification circuit, the relay switch, the normally-closed switch and the ignition circuit form a passive testing system for a drunk driver, and if the alcohol content is overproof, the normally-closed switch is turned on and an engine cannot be started, thereby preventing the driver from drunk driving; and the respirator, the alcohol testing instrument and the alarm form an active testing system, so that the driver can test own alcohol content by self.
