when the user lifts up the seal (303) and the seal (303) leaves the paper, the main control board (5) needs to identify the paper pattern and the color brightness, wherein the main control board (5) compares the shot paper pattern with an authorization sample drawing for comparing the examined and approved files allowed to be stamped with the stored stamp (303) base drawing, the stamping on the unauthorized files can be prevented from being mistakenly effective through comparison, if the matching degree of contrast exceeds a specified fourth threshold value, the content of the seal at the time is determined to be error-free, otherwise, the seal (303) is judged to be selected wrongly or the paper file is selected wrongly, wherein the difference value of the contrast between the color brightness of the seal (303) and the designated color brightness exceeds a designated fifth threshold value, the seal display at the time is determined to be error-free, when the contrast difference between the color brightness of the seal (303) and the designated color brightness is lower than a designated sixth threshold, the main control board (5) accumulates the number of times of color darkening;

when the stamping is successful, the stamping times are accumulated to be 1 and displayed on an OLED display screen (602), and a main control panel (5) drives two LED lamps (501), a buzzer (502) and the OLED display screen (602) to act;

when the stamping fails, the stamping times are accumulated to be 1 and displayed on an OLED display screen (602), and a main control panel (5) drives two LED lamps (501), a buzzer (502) and the OLED display screen (602) to act;

the master control board (5) sets the reset of the timer to be T =0, and a user carries out the next operation according to the prompts of the LED lamp (501), the buzzer (502) and the OLED display screen (602);

step f, reapplying the printing oil: when the contrast difference value between the color brightness of the seal (303) and the designated color brightness is continuously and repeatedly lower than a designated sixth threshold value, namely, the color is repeatedly darker, it is judged that the seal (303) needs to be applied with printing ink, the main control board (5) drives the two LED lamps (501), the buzzer (502) and the OLED display screen (602) to act, the main control board (5) controls the stepping motor (302) to act in the reverse direction, the stepping motor (302) pulls back the seal (303) to the initial position upwards, a user closes the main body cabin (3) on the bottom cover cabin (4) and locks the electromagnetic lock (403) according to a confirmation key, the printing ink is reapplied according to the method in the step c, and the methods in the step d and the step e are installed for continuous stamping, wherein the stamping times are continuously accumulated;

if the color brightness of the seal stamp (303) after the ink is reapplied is continuously darker and is continuously lower than a specified seventh threshold value for multiple times according to the method in the step c, the main control board (5) drives the two LED lamps (501), the buzzer (502) and the OLED display screen (602) to act, and the inkpad (402) needs to be replaced at the moment;

step g, the seal (303) is reset and locked: when the stamping times reach the permitted stamping times of the user, or the user presses a confirmation key for keeping for 5s, or the timer counts that the operation time of single stamping is greater than a specified eighth threshold value, or the communication abnormality of the communication equipment and the monitoring center exceeds a specified ninth threshold value; the main control board (5) drives the two LED lamps (501), the buzzer (502) and the OLED display screen (602) to act, the main control board (5) controls the stepping motor (302) to act in the reverse direction, and the stepping motor (302) pulls back the stamp mark (303) to an initial position;

when a user buckles the main body cabin (3) in the bottom cover cabin (4), the distance value and the photosensitive value of the main control board (5) are returned by the stamp (303) sensor, and after the fact that the bottom cover cabin (4) and the main body cabin (3) are buckled into a whole is judged, the main control board (5) issues a locking instruction to drive the electromagnetic lock (403) to act, and the lock pin of the electromagnetic lock (403) moves into the lock hole (308) to complete locking; the seal locking is judged to be successful by the main control according to the state of the electromagnetic lock (403) and the feedback data of the seal (303) sensor, the main control board (5) drives the two LED lamps (501), the buzzer (502) and the OLED display screen (602) to act, and the main control board (5) reports the seal use end to the monitoring center through the communication equipment.

10. The intelligent stamp using method according to claim 9, wherein the content displayed in the OLED display screen (602) is synchronized to the monitoring center via the communication device together with the "time stamp" information; when the electromagnetic lock (403) is illegally opened under the condition of incorrect authorization, the main control board (5) drives the buzzer (502) to continuously conduct high-frequency buzzing alarm, an illegal operation alarm signal is generated, and then the illegal operation alarm signal attached with a 'time mark' is sent to the monitoring center by the main control board (5).
