Embodiment
Of the present invention kind of emergency data quality control system, as shown in Figure 1, is made up of quality of data Rule Extraction unit 1, quality of data rule control module 2 and quality of data rule base 3 three parts.Quality of data Rule Extraction unit 1 is for extract different quality of data rules from quality of data rule base 3, and the quality of data rule of extraction is sent to quality of data rule control module 2.Quality of data rule control module 2 receives the quality of data rule that quality of data Rule Extraction unit 1 sends, and the data content that uses the quality of data rule of receiving to input data to data entry terminal 4 carries out quality check.Quality of data rule base 3 is the databases for storing quality of data rule, supports the function of interpolation, deletion, amendment and retrieve data quality rule.
Fig. 2 is the data flowchart of a kind of emergency data quality control system of the present invention.The current situation information of accident is sent to quality of data Rule Extraction unit 1 by Police Command Center.Data entry terminal 4 is inputted a new data, and the data type of input data is sent to quality of data Rule Extraction unit 1, and the data content of input data is sent to quality of data rule control module 2.The data type that data are inputted according to the grade of the type of accident, accident and data entry terminal 4 in quality of data Rule Extraction unit 1 is extracted quality of data rule from quality of data rule base 3, and these rules are sent to quality of data rule control module 2.Quality of data rule control module 2 carries out quality check to the data content of input data one by one according to these quality of data rules, if find that the data content of input data does not meet the requirement of certain data quality rule, just error message is sent to the data entry terminal 4 of input data, data entry terminal 4 is selected to cancel data input or is re-entered according to error message.If the data content of input data meets the requirement of each data quality rule, these data are sent to data updating unit 5 by 2 of control modules of quality of data rule, and will input Data Update to emergency data storehouse 6 by data updating unit 5.
Fig. 3 is the method flow diagram of a kind of emergency data method of quality control of the present invention.Set forth a kind of emergency data method of quality control of the present invention by a specific embodiment below.
Event context: event of fire has together occurred in the wood land in certain city, has multiple emergency mechanisms to participate in emergency disposal rescue, comprises city's Police Command Center, Municipal Forestry Bureau, fire department of city, municipal health bureau etc.
City's Police Command Center has been issued current accident situation information: the forest fire that this city occurs is at present positioned at A district and to the north of B district intersection ten kilometers, and disaster-stricken area of woods exceedes approximately 200 hectares, causes 5 people's death.
Steps A 1: the staff L of Municipal Forestry Bureau is in the data that data type be " expert " of data entry terminal input, the field that the packet that type is " expert " in emergency data storehouse 6 contains has " name, mobile phone, professional speciality, work unit, ID (identity number) card No., post, academic title " etc.
Steps A 2: the data type of input data is sent to quality of data Rule Extraction unit 1 by the data entry terminal of the staff L of Municipal Forestry Bureau, and data type is " expert ".
Steps A 3: the data content of input data is sent to quality of data rule control module 2 by the data entry terminal of the staff L of Municipal Forestry Bureau, and data content is " name: Zhang San; Mobile phone: 139******** (note: save rear 8 bit digital in reality herein); Specialty speciality: forest fire is puted out a fire to save life and property ".
Steps A 4: quality of data Rule Extraction unit 1 is from Police Command Center Dynamic Acquisition accident situation information, and with reference to the rank division method to forest fire event in this urban forests fire disaster emergency prediction scheme, analysis obtains:
(a) the current type of subject of accident: forest fire
(b) the current grade of accident: 3 grades
(c) the current coverage of accident: A district and to the north of B district intersection ten kilometers, approximately 200 hectares, disaster area
In the time that data type is " expert ", in quality of data rule base 3, there is different quality rules, wherein part quality rule example is as following table.
To the requirement of quality of data dynamic change along with the urgency level of accident, requirement may improve also and may reduce.Such as under regular situation, need user input information such as expert " professional speciality, work units " be need to be repeatedly data exchange process, in conventional data updating process, be necessary, because can ensure better the integrality of data.But in the situation that the accident state of affairs is urgent, in order to save time, can suitably ignore the factor that needs consideration under some normal conditions, while generation such as vital emergent event together, the urgent expert info of submitting to of certain department all can match with the required expert's of this accident professional speciality conventionally, under this precondition, it is most important can relating to expert the very first time, therefore under this condition, need consider data integrity quality rule can be different under normal condition, the requirement of the integrity rule that is as above " expert " to data type in table can decrease on the contrary with the rising of accident grade.
For this example, quality of data Rule Extraction unit 1 utilizes the current type of subject of accident, the current grade of accident and the current coverage of accident, be the condition of " expert " with inputting data type, two data quality rules below extracting from above table.
Data integrity rule R1: " name, mobile phone, professional speciality, work unit " can not be respectively empty; The rules of data consistency R2: cellular phone is necessary for significant figure.
Steps A 5: above-mentioned data integrity rule R1 and the rules of data consistency R2 are sent to quality of data rule control module 2 by quality of data Rule Extraction unit 1.
Steps A 6: quality of data rule control module 2 is the data content " name: Zhang San to input data according to R1 and R2; Mobile phone: 139********; Specialty speciality: forest fire is puted out a fire to save life and property " carry out quality check.For the rules of data consistency R2, the data content of input data meets the demands.But for data integrity rule R1, the data content of input data lacks work unit's information, does not therefore meet the demands.
Steps A 7: because the data content of inputting data is by the inspection of data integrity rule R1, quality of data rule control module 2 " lacks error message work unit's information " and sends to the data entry terminal of the staff L of Municipal Forestry Bureau, work unit's information that the staff L of Municipal Forestry Bureau can cancel data input or supplement this expert data according to error message.
Steps A 8: when the data content of input data has passed through the inspection of every item number according to quality rule, quality of data rule control module 2 sends to data updating unit 5 by these data and completes Data Update.
Along with impact development, if city's Police Command Center has upgraded accident situation information, when accident grade changes, quality of data Rule Extraction unit 1 extracts also corresponding the changing of quality rule obtaining.
Although above according to specific embodiment, invention has been described, the invention is not restricted to this, those skilled in the art can carry out various amendments according to principle of the present invention.Therefore every amendment of carrying out according to principle of the present invention, is all construed as and is included in protection scope of the present invention.
