Description
技术领域Technical Field
本发明涉及酒精锁校准领域，具体涉及一种用于酒精锁的便携式校准系统及方法。The invention relates to the field of alcohol lock calibration, and in particular to a portable calibration system and method for an alcohol lock.
背景技术Background Art
随着我国经济社会高质量发展，各类机动车的大量增加，酗酒滋事、酒后驾车所引发的刑事案件、治安案件及交通事故亦日渐增多。每年由于酒后驾车引发的交通事故达数万起；而造成死亡的事故中50％以上都与酒后驾车有关。酒后驾车的危害触目惊心，已经成为交通事故的第一大“杀手”。With the high-quality development of my country's economy and society, the number of various types of motor vehicles has increased significantly, and criminal cases, public security cases and traffic accidents caused by drunk driving have also increased. Every year, there are tens of thousands of traffic accidents caused by drunk driving; and more than 50% of fatal accidents are related to drunk driving. The harm of drunk driving is shocking, and it has become the number one "killer" of traffic accidents.
目前，酒后驾车的治理主要是依靠公安交通部门现场使用的警用酒检仪判断驾车司机是否酒后驾车。该方法由于警力有限，在时间和空间的查处覆盖面非常有限。交通管理部门的查处工作制止的是正在进行的酒后驾驶行为，无法在源头上制止驾驶员酒后驾车。若能在酒后驾驶行为前制止机动车启动，将有效杜绝酒后驾驶的行为，将给人民群众的生命和财产带来更大的安全保障。At present, the governance of drunk driving mainly relies on the police alcohol detector used on-site by the public security traffic department to determine whether the driver is driving under the influence of alcohol. Due to the limited police force, this method has a very limited coverage in time and space. The investigation and punishment work of the traffic management department stops the ongoing drunk driving behavior, and cannot stop the driver from driving under the influence of alcohol at the source. If the motor vehicle can be stopped from starting before the drunk driving behavior occurs, the behavior of drunk driving will be effectively eliminated, which will bring greater safety protection to the lives and property of the people.
酒精锁是安装在汽车的点火装置内以阻止驾车人在血液中的酒精浓度超过安全标准时启动汽车的装置，酒精锁需要驾车司机在汽车点火前先进行吹气测试，如果测试结果超过安全水平，汽车联锁装置将会被激活，汽车将无法启动。经酒精锁测试认定驾驶员没有饮酒后，酒精锁才会开启，驾驶员才可以安全启动汽车。The alcohol lock is a device installed in the ignition of the car to prevent the driver from starting the car when the alcohol concentration in the driver's blood exceeds the safety standard. The alcohol lock requires the driver to perform a breathalyzer test before the car is ignited. If the test result exceeds the safety level, the car interlock device will be activated and the car will not be able to start. The alcohol lock will only be opened after the alcohol lock test determines that the driver has not drunk alcohol, and the driver can start the car safely.
由于当前的酒精锁一般使用燃料电池作为传感器，而该传感器的特性是输出随着使用的时间或次数下降。所以使用该方案时，需要进行实时标定才能保证测试精度。因酒精锁与汽车启动装置是联锁装置，不易拆卸，要验证其准确性需要通过酒精锁校准装置进行校准。Since current alcohol locks generally use fuel cells as sensors, and the characteristic of this sensor is that the output decreases with the time or number of times it is used, real-time calibration is required to ensure the test accuracy when using this solution. Since the alcohol lock and the car starting device are interlocking devices and are not easy to disassemble, to verify its accuracy, it is necessary to calibrate it using an alcohol lock calibration device.

显示单元6：接收用户的操作指令、参数设置以及进行标定结果显示。Display unit 6: receives user's operation instructions, parameter settings and displays calibration results.
各单元的具体实现如下：The specific implementation of each unit is as follows:
所述气体控制单元2包括依次连接的气瓶21(装有空气乙醇，浓度可配)、减压阀22、流量控制器23以及气体管路24，所述气体管路24的出口与至少一台酒精锁200的进气口连接。减压阀22物理控制气瓶21的气体开关，并进行减压处理。流量控制器23通过串口RS232与主控单元1进行通信，控制气体通路的气体流量。同时，流量控制器23充当电子气阀的功能，控制气体管路24的导通与关闭。The gas control unit 2 includes a gas cylinder 21 (containing air ethanol, the concentration can be adjusted), a pressure reducing valve 22, a flow controller 23 and a gas pipeline 24 connected in sequence, and the outlet of the gas pipeline 24 is connected to the air inlet of at least one alcohol lock 200. The pressure reducing valve 22 physically controls the gas switch of the gas cylinder 21 and performs pressure reduction. The flow controller 23 communicates with the main control unit 1 through the serial port RS232 to control the gas flow of the gas passage. At the same time, the flow controller 23 acts as an electronic gas valve to control the conduction and closing of the gas pipeline 24.
所述酒精锁控制单元3，包括依次连接的系统串口控制模块31、至少一个RS485串口控制模块32以及串口线路通路；每一个待校准酒精锁200分别与一个RS485串口控制模块32连接；所述系统串口控制模块31用于接收主控单元1发送的串口指令，所述串口指令用于使外接的酒精锁200进入特定状态(比如，标定状态)；所述至少一个RS485串口控制模块32用于转发或过滤串口指令，使指定的酒精锁200进入特定状态实现校准。The alcohol lock control unit 3 includes a system serial port control module 31, at least one RS485 serial port control module 32 and a serial port line path which are connected in sequence; each alcohol lock 200 to be calibrated is connected to an RS485 serial port control module 32 respectively; the system serial port control module 31 is used to receive a serial port instruction sent by the main control unit 1, and the serial port instruction is used to make the external alcohol lock 200 enter a specific state (for example, a calibration state); the at least one RS485 serial port control module 32 is used to forward or filter the serial port instruction so that the specified alcohol lock 200 enters a specific state to achieve calibration.
由于串口通常为一对一进行通讯。本系统通过系统串口控制模块31发送指定RS485串口的控制指令，对应的RS485串口控制模块32执行指令从而控制对应的酒精锁200，实现一对多通讯。比如，同时测试3台酒精锁时，3台酒精锁200分别与3个RS485串口控制模块32连接。当系统串口控制模块31发送的串口指令为标定第1台酒精锁时，第一RS485串口控制模块32转发该串口指令，同时第二第三RS485串口控制模块32过滤该指令，不进行转发。当第1台酒精锁200标定完成后，系统统串口控制模块31发送标定第2台酒精锁200的串口指令，第二RS485串口控制模块32转发该串口指令，同时第一第三RS485串口控制模块32过滤该指令，不进行转发，依此类推。Since the serial port is usually one-to-one communication. This system sends a control instruction for the specified RS485 serial port through the system serial port control module 31, and the corresponding RS485 serial port control module 32 executes the instruction to control the corresponding alcohol lock 200, realizing one-to-many communication. For example, when testing three alcohol locks at the same time, the three alcohol locks 200 are connected to three RS485 serial port control modules 32 respectively. When the serial port instruction sent by the system serial port control module 31 is to calibrate the first alcohol lock, the first RS485 serial port control module 32 forwards the serial port instruction, and the second and third RS485 serial port control modules 32 filter the instruction and do not forward it. When the calibration of the first alcohol lock 200 is completed, the system serial port control module 31 sends a serial port instruction for calibrating the second alcohol lock 200, and the second RS485 serial port control module 32 forwards the serial port instruction, and the first and third RS485 serial port control modules 32 filter the instruction and do not forward it, and so on.
通过对待标定酒精锁200进行串口通信，自动控制酒精锁200进入标定状态，无需手动点击。通过多个RS485串口控制模块32实现串口指令的转发或过滤，实现一次标定操作可以标定多台设备，做到数据互不干扰。By performing serial communication with the alcohol lock 200 to be calibrated, the alcohol lock 200 is automatically controlled to enter the calibration state without manual clicking. The serial port command is forwarded or filtered through multiple RS485 serial port control modules 32, so that multiple devices can be calibrated in one calibration operation without data interference.
所述网络传输单元4用于与后台建立网络连接，进行数据传输；可以包括以太网模块以及WIFI模块。通过网络传输单元4的通信，接入到广域网内，实现装置和后台的数据通信。The network transmission unit 4 is used to establish a network connection with the background for data transmission, and may include an Ethernet module and a WIFI module. Through the communication of the network transmission unit 4, access is made to the wide area network to realize data communication between the device and the background.
所述数据库单元5用于对标定的记录进行保存，比如当前的标定时间、设备编号、设备型号、标定浓度、标定流量、标定结果以及操作者信息。在一种可能的实现方式中，数据库单元通过Android系统自带的Sqlite3.0数据库，保存多张数据表。The database unit 5 is used to save calibration records, such as current calibration time, device number, device model, calibration concentration, calibration flow, calibration results and operator information. In a possible implementation, the database unit saves multiple data tables through the Sqlite3.0 database provided by the Android system.
所述显示单元6用于接收用户的操作指令、参数设置以及进行标定结果显示。The display unit 6 is used to receive user operation instructions, parameter settings and display calibration results.
实施例二Embodiment 2
