The user uses this user information that the public security personnel entered just automatic matching after the ID card discernment at cell-phone APP end, connects according to the room number of predetermineeing automatically.
The backstage supporter logs on the function module 224 to manage the public security personnel, and the public security personnel logs on the system through the set number and password.
The evidence obtaining module 228 is used for the public security personnel to inquire the record, call the notice, call the evidence list, seal after the user confirms that the signature is correct, and export and print the document.
The police management background 22 further comprises a role authority module 222, a stamp module 225, an assignment module 226 and an inquiry writing module 227. The role permission module 222 is used for managing the menu permission of the system for the public security personnel at different levels to log in, and setting which roles can view which permission menus.
The stamp module 225 is used for uploading one-to-one stamp pictures by public security personnel, so that the stamping operation is convenient in the preparation of interrogation data.
The identification module 226 is used for public security personnel to display preset information needing identification to the user, so that the user can conveniently identify the information in the inquiries. The basic data are title and remark. After the saved title is selected, N pictures (head portraits) can be added to the saved title, so that the user can conveniently identify the saved title in the trial. And recording the assigned photos in the user assignment process.
The inquiry record module 227 is used for filling in the inquiry record by the police personnel at the background, and storing the inquiry record in a local disk and printing the inquiry record. The query script is paginated in accordance with the A4 print size, filled in, saved locally and printed.
In addition, the public security personnel can also call related notice books and evidence lists, and the public security personnel can edit and page the preset calling notice book template which is stamped with the stamp. For the evidence list, the title is preset by the public security personnel, and other contents are edited during inquiry. It is paginated in conjunction with a4 print size, filled in, saved locally and printed.
