The invention provides an anti-cheating alcohol interlocking detection method and system, and the method comprises the steps: entering a pre-starting locking state in response to a detected driving side vehicle door opening and driver seating event, and prohibiting vehicle starting and power output; after it is detected that the driving side vehicle door is closed, an alcohol detection process is started, a driver is prompted to conduct an expiration test, and first biological characteristic information of the driver is synchronously collected in the expiration test process; acquiring an expiration alcohol detection result, if the detection result is that the expiration alcohol passes, storing the first biological characteristic information, and releasing the prohibition on the starting of the vehicle; in response to the fact that the vehicle is engaged in the driving gear, second biological characteristic information of a driver on the driving position is collected; comparing the second biological characteristic information with the stored first biological characteristic information; if yes, the vehicle is allowed to run normally; and if the comparison result is inconsistent, a safety intervention measure is executed, so that the anti-cheating intrinsic safety of the alcohol lock system is greatly improved.

This invention relates to the field of medical breath testing equipment technology, and provides an integrated valve-pump electronic control structure for a breath testing device. The structure includes a microcontroller unit, a multi-channel valve drive circuit, a pump drive circuit, and a bus interface circuit for connecting pressure sensors and gas sensors, all mounted on the same control board. The microcontroller unit outputs valve control signals and pump control signals, which drive the multi-channel valves and the circulating pump respectively through the valve drive circuit and the pump drive circuit. The bus interface circuit connects to the pressure sensors and gas sensors via a unified communication bus and provides the collected sensor signals to the microcontroller unit. When the system is powered on or reset, the multi-channel valve drive circuit and the pump drive circuit enter a preset default safety state, closing the valves and stopping the circulating pump or entering a safe venting mode, thereby improving the operational safety and reliability of the device under abnormal operating conditions.
