Column.
As shown in Fig. 2, the PWM square-wave signal of different duty represents different numbers.The duty ratio of square wave is 0% expression
Number 0, duty ratio are 10% expression number 1；Duty ratio is 20% expression number 2 ... and so on, and duty ratio is 90% table
Registration word 9.If the identification code for the treatment of fluid supply module 20 is 0347526189, then the identification code passes through 10 continuous PWM
Square-wave signal indicates that the duty ratio of these continuous square waves is once 0%, 30%, 40%, 70%, 50%, 20%, 60%,
10%, 80% and 90%.Fig. 3 shows the 5th P05 and the 6th square wave P06 in square wave sequence.
Those skilled in that art should be understood that apart from the above any communication mode that can be realized identical function all may be used
To use.
It should also be appreciated by one skilled in the art further including except treatment fluid supply module 20 and treatment fluid in SCR device
In the case where other modules except jet module 30, the authentication module of the application can in a manner analogous to that described above with it is described its
Its module communication connection, and can with above-mentioned similar mode to the target component in other described modules or other modules into
Row verifying.
According to the application, utilization is typically comprised using the method that SCR device as described above carries out vehicle exhaust processing
Object module (treatment fluid supply module 20 and/or treatment fluid jet module in the authentication module verifying SCR device of SCR device
It 30) whether is expected or original-pack module or the step of component.Preferably, energization of this step before vehicle motor igniting
The self-test stage carries out.Specifically, this step includes, according to presetting or in response to the human-computer interaction device from vehicle
User's instruction is received the identity information for indicating object module or target component by the authentication module of SCR device from object module
Identification code and make the step of it is compared with the identification code of pre-stored expected module or component.As above-mentioned, verifying mould
Block can send query message to object module first, then receive the feedback from object module, or only receive target
The identification code that module active transmission comes.
It is further preferred that according to actual needs, the control unit 40 of authentication module, example as shown in figure 1 is able to respond in current
Object module or component be not expected module or component and issue alarm.Correspondingly, authentication module is configured to
It is communicated to connect with the alarm module being optionally arranged and/or the vehicle man machine's interactive device being optionally arranged.Alarm module and people
Machine interactive device can be presented as widely known any viable means in the art.
SCR device according to the application includes authentication module, the object module or object module being able to verify that in SCR device
In target component whether be expected module or component.It is in each of SCR device module or module according to the application
Component assign and be different from that the exclusive identification code of other modules or component is the module for verifying SCR device or whether component is expected
Module or component a kind of embodiments possible.However, it will be understood to one skilled in the art that can be realized this verifying function
Can possible form be not limited solely to above-mentioned identification code, on the contrary, those skilled in that art it is conceivable that can represent it
It can be used different from the unique features of other supply modules.The avatar of identification code is also not limited to above-mentioned square wave sequence
Form.
Using the SCR device of the application, as needed, those skilled in the art can combine SCR device or its module
Or use data, performance data and the other related datas of component, more completely, targetedly track or record SCR dress
The service performance set and more comprehensively for statistical analysis.This provides advantage and foundation for the subsequent research and development and improvement of product.
In addition, user or client may need that target product is verified or assessed using this additional information, such as in purchase two
When handcart.
If necessary, verification result can be carried out showing or triggers real-time, local or remote alarm when necessary, by
This is realized to the composition module of SCR device or a degree of monitoring of component parts.
