Embodiment 1
[0034] Such as figure 1 The illustrated embodiment is a detection system for preventing drunk driving, which includes an alcohol detector 1, an automobile engine management system 4, a driver's license scanner 6, a lung capacity tester 2, a data collector 7, and an alarm processing system. Device 5 and detection controller 3; the driver's license scanner is connected with the data collector, the data collector, spirometry instrument and alcohol detector are respectively connected with the detection controller, and the detection controller is respectively connected with the alarm processing device and the automobile engine management system is connected. The alcohol detector is a breath-type semiconductor alcohol detector, and the side wall of the blowing port of the spirometer is provided with a hole for passing through the blowing port of the alcohol detector. The testing controller includes a horn and a storage unit provided with testing software. The alarm processing devi...
Embodiment 2
[0047] The structural part of embodiment 2 is the same as that of embodiment 1. Such as image 3 As shown, step d in step (5) in embodiment 1 is replaced by the following steps, and other steps are the same as in embodiment 1.
[0048] Such as image 3 as shown,
[0049] If the driver's lung capacity is greater than or equal to the standard vital capacity and the driver drinks alcohol, the car engine management system can only drive the car at a speed of 10 kilometers to 30 kilometers; the detection controller controls the speed of the car through the car engine system and is inversely proportional to the alcohol content. The higher the alcohol content, the lower the speed of the car; at this time, the driver is allowed to drive on country roads, roads in urban areas, etc., and cannot enter the main road.
Embodiment 3
[0051] Such as figure 1 As shown, the alarm processing device 4 in Embodiment 3 includes an alarm horn, a remote help-seeking device, and a satellite positioning system. Other structural parts are the same as in Embodiment 1.
[0052] Such as Figure 4 As shown, the implementation steps include all the steps of Example 1, and the step d in the step (5) also includes the following steps:
[0053] The alarm processing device informs the driver that the alcohol test is unqualified through the horn voice; and sends the vehicle positioning information in the satellite positioning system and the driver's status to the emergency contact person, the driver company and the traffic control department through the remote help device.
[0054] It should be noted that, in addition to the above-mentioned embodiments, according to actual needs, the detection system and control method for preventing drunk driving described in the present invention can selectively add various alcohol detector...
