Description
Technical Field
The invention relates to alcohol detection equipment, in particular to an airway return-to-zero alcohol tester and a detection method thereof.
Background
In order to maintain the personal safety of people and fight against drunk driving and drunk driving to harm the safety of other people, traffic law enforcement departments continuously strengthen the investigation and treatment of drunk driving. In the process of law enforcement and investigation at urban roads and highway checkpoints, an alcohol detector is usually used for detecting the alcohol concentration contained in the gas exhaled by a driver, and the alcohol concentration is used as the basis for investigating drunk driving and drunk driving.
The new national standard (national standard GB/T21254-2017 of the people's republic of China) requires that the alcohol tester has a zero resetting function after blowing detection, and the currently adopted method is mainly a sensor zero resetting method, but whether the zero resetting is carried out in a gas pipeline of the alcohol tester cannot be determined, and only the residual alcohol gas can be naturally scattered. If the detection accuracy is considered, the next detection can be performed only after residual gas and water vapor in the detection equipment are scattered, and the detection accuracy of the next user cannot be influenced by the use of the previous user.
In actual use, the alcohol detector generally needs to be used continuously, and after one detection is completed, the alcohol detector is quickly prepared to perform the next detection, so that the alcohol detector generally only performs sensor resetting. After the instrument is used for the first time, the worker does not wait for the residual gas in the instrument pipeline to be completely dispersed, and then uses the instrument for the second time; due to the existence of residual gas in the air channel, the detection accuracy of a subsequent driver is greatly influenced.
In addition, in the process of blowing in alcohol detection, the gas to be detected is easily condensed on the gas passage pipe wall, especially on the irregular gas passage pipe wall, even forms water drops, so that the difficulty of cleaning the gas passage after detection is increased, and even the gas passage is not cleaned completely or the cleaning time is long.
In order to solve the above problems, people are always seeking an ideal technical solution.

Example 5
The embodiment provides a detection method of the airway return-to-zero alcohol tester, which comprises the following steps:
the current detection cycle of the airway return-to-zero alcohol tester comprises a preparation time period, a concentration detection time period and an airway return-to-zero time period;
the alcohol detector enters a current detection period and starts to time in a preparation period; when the timing of the preparation time period reaches the preset time, the alcohol detection device starts to collect the concentration value of the gas to be detected in the air passage and transmits the concentration value to the main controller, and meanwhile, the timing of the concentration detection time period is started;
when the concentration detection time period reaches the preset time, the air exhaust device starts to exhaust residual gas in the air passage to the outside of the alcohol tester, and meanwhile, the air passage zero resetting time period is started to be timed; and when the timing of the airway zeroing period reaches the preset time, closing the air suction device.
It should be noted that, the current detection cycle refers to the whole process from the start of detection by the detected driver to the completion of the airway zeroing work; diffusing the gas to be detected in the air passage in the preparation period to prepare for sampling of the alcohol detection device; in the concentration detection period, sampling the gas to be detected in the air passage by the alcohol detection device, and converting the gas into a gas concentration electric signal; in the air passage zero resetting time period, the air exhaust device is started to discharge residual gas in the air passage to the outside of the alcohol tester, so that the aim of air passage zero resetting is fulfilled.
Example 6
This example differs from example 5 in that:
the main controller is connected with an air blowing pressure detection device, and the air blowing pressure detection device is communicated with the air passage in a sealing manner and is used for detecting whether gas to be detected enters the air passage;
the preparation period comprises a blowing confirmation period and a gas diffusion period; the alcohol detector enters a current detection period, timing is started in an air blowing confirmation period, and meanwhile, the air blowing pressure detection device starts to acquire a pressure value of gas to be detected in an air passage and transmits the pressure value to the main controller; if the blowing pressure value detected by the blowing pressure detection device exceeds a preset value, timing is finished in a blowing confirmation time period, timing is started in a gas diffusion time period, and meanwhile, an air extraction device is started to guide the flow direction of the gas to be detected in the air passage; and when the gas diffusion time period reaches the preset time, closing the gas extraction device.
In embodiment 5, the air exhaust device is started to clean the air passage after the detection of the alcohol concentration is completed, but the gas to be detected is easily condensed on the wall of the air passage in the process of blowing in the alcohol detection, and even water drops are formed; the difficulty of cleaning the air passage after the concentration detection is finished is increased under the condition, and the air passage is easy to be cleaned unclean or the cleaning time is long; especially, it is inconvenient to clean the irregularly shaped airway wall.
Therefore, the present embodiment detects whether the gas to be detected enters the air passage by arranging the blowing pressure detection device; the timing ending time of the blowing confirmation time period is dynamic, when the blowing pressure value detected by the blowing pressure detection device exceeds a preset value, the timing ending time of the blowing confirmation time period is timed, and the air extraction device is started in time to guide the flow direction of the gas to be detected in the air passage, so that the gas to be detected is prevented from diffusing in no direction; under the combined action of blowing force and suction force of the air exhaust device, the gas to be measured is not easy to form vapor condensation on the wall of the air passage pipe, and the air passage cleaning efficiency is improved.
Fig. 4 shows a workflow of a detection method of the airway return-to-zero alcohol tester in the present embodiment.
Example 7
This example differs from example 5 in that: the main controller is connected with an air blowing pressure detection device, and the air blowing pressure detection device is communicated with the air passage in a sealing manner and is used for detecting whether gas to be detected enters the air passage;
the preparation period comprises a blowing confirmation period and a gas diffusion period; the alcohol detector enters a current detection period, timing is started in an air blowing confirmation period, and meanwhile, the air blowing pressure detection device starts to acquire a pressure value of gas to be detected in an air passage and transmits the pressure value to the main controller; when the timing of the blowing confirmation time period reaches the preset time, if the blowing pressure value detected by the blowing pressure detection device does not exceed the preset value, starting an air extraction device to collect the gas to be detected into the air passage, and starting timing the gas diffusion time period; and when the gas diffusion time period reaches the preset time, closing the gas extraction device.
In practical application, the detected driver is not matched or loses blowing capacity, and the detected driver cannot be effectively detected, so that the time and the energy of workers are wasted.
Therefore, the present embodiment detects whether the gas to be detected enters the air passage by arranging the blowing pressure detection device; and after the timing of the blowing confirmation time interval is finished, the blowing pressure value detected by the blowing pressure detection device still does not exceed the preset value, and the detected driver does not cooperate or loses blowing capacity, the air extraction device is started immediately, and the gas to be detected is collected into the air passage to assist the detected driver in wine detection and detection, so that the aim of detecting drunk driving is fulfilled.
Example 8
The present embodiment differs from the above embodiments in that: the air exhaust device is provided with a variable frequency motor for driving the air exhaust device to rotate, and the variable frequency motor is connected with the main controller through a frequency converter; the main controller controls the air extractor to operate according to the concentration value of the received gas to be tested so as to discharge the residual gas in the air passage out of the alcohol tester, and the following steps are executed:
if the concentration value of the gas to be detected is less than 11mg/100mL, a first cleaning instruction is sent to a variable frequency motor of the air extraction device, and the air extraction device is controlled to work at a first rotating speed within the air passage zero resetting time period; if the concentration value of the gas to be detected is greater than or equal to 11mg/100mL and less than or equal to 70mg/100mL, sending a second cleaning instruction to a variable frequency motor of the air exhaust device, and controlling the air exhaust device to work at a second rotating speed within the air passage zeroing time period; and if the gas concentration value is greater than 70mg/100mL, sending a third cleaning instruction to a variable frequency motor of the air exhaust device, and controlling the air exhaust device to work at a third rotating speed within the air passage zeroing time period.
It can be understood that, when the concentration value of the gas to be tested is less than 11mg/100mL, it indicates that the driver to be tested is not drinking wine or the alcohol concentration in the airway is very low, and the next alcohol test result is not influenced or is very slightly influenced, and at this time, the air exhaust device operates at the first rotation speed. Preferably, the first rotation speed is zero, i.e. the next test is performed directly without opening the airway purge. When the concentration value of the gas to be measured is greater than or equal to 11mg/100mL and less than or equal to 70mg/100mL, it indicates that the alcohol concentration in the airway may affect the next test result, and the airway needs to be cleaned continuously. When the gas concentration value is larger than 70mg/100mL, the alcohol concentration in the air passage is larger, and a larger rotating speed and a longer time are needed for cleaning.
In this embodiment, the first rotation speed is less than the second rotation speed, and the second rotation speed is less than the third rotation speed; the airway zeroing time period corresponding to the first rotating speed is less than the airway zeroing time period corresponding to the second rotating speed, and the airway zeroing time period corresponding to the second rotating speed is less than the airway zeroing time period corresponding to the third rotating speed.
The first rotation speed, the second rotation speed, the third rotation speed and the respective cleaning time of the air extractor can be set according to parameters such as an air extraction method, the type of the air extractor, the air volume and the like, and specific conditions during testing. The values of the first rotating speed, the second rotating speed, the third rotating speed and the corresponding cleaning time are not fixed, and can be set according to different air path structures and specific test conditions, and are increased or decreased appropriately. The division interval of the alcohol concentration is not fixed, and more specific division may be performed according to the alcohol gas concentration in the airway, and the fourth rotation speed, the fifth rotation speed, and the like may be increased to achieve an optimal configuration.
For example, when the air extractor adopts a fan air extraction method, if the fan size is 20mm multiplied by 10mm, the maximum rotating speed is 13000rpm, and the maximum air quantity is 0.037m 3/min. When the driver is unknown whether to drink, the first rotating speed of the air extractor is set to be 6000 rpm, and the air passage zero recovery time period corresponding to the first rotating speed is set to be 0-2 s; when alcohol gas exists in the air passage, a second rotating speed is set to 9000rpm, and the air passage zero resetting time period corresponding to the second rotating speed is set to 3 s; the third rotating speed is set to 13000rpm, and the air passage zero resetting time period corresponding to the third rotating speed is set to 5 s.
Therefore, the cleaning time of the rotating speed of the air extracting device is intelligently adjusted according to the detection result of the alcohol detection device, when high-concentration alcohol gas exists in the air passage, the rotating speed is automatically increased, the cleaning efficiency is improved, and the time is saved; and when alcohol gas concentration is lower in the air flue, the rotating speed is automatically kept, reduced or the air exhaust is closed, so that the electric quantity can be saved, the service time of the instrument is prolonged, and the aim of efficiently and intelligently cleaning the air flue is fulfilled.
Example 9
The present embodiment differs from the above embodiments in that: the tester shell is provided with a camera for collecting face information of a detected driver; if the face information of the detected driver is consistent with the face information in the prestored driving license information, starting to time the preparation time interval; and if the face information of the detected driver is inconsistent with the face information in the prestored driving license information, marking the detected driver and starting to time the preparation time interval.
In the embodiment, the airway return-to-zero alcohol tester stores the driving license information in advance, carries out face comparison before detection, and directly starts to prepare time interval timing if the face information of the detected driver is consistent with the face information in the pre-stored driving license information; if the detected time interval is not consistent with the preset time interval, marking the detected driver, and then starting to time the preparation time interval. Meanwhile, the detection result of the alcohol detection device and the face information of the detected driver are stored in a correlated mode so as to facilitate subsequent searching and analysis.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the invention or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the invention as defined by the appended claims.
