The invention provides a security control method, an operation management billing system, an application store and a mobile terminal. The method includes receiving a billing short message sent by a mobile terminal, wherein the billing short message includes short message billing service content, a random number, and first security check information, and the short message billing service content includes an application identification of a mobile terminal application ; According to the user identification of the mobile terminal and the application identification, obtain the security serial number and the application version identification corresponding to the user identification and the application identification, adopt a digest encryption algorithm, and encrypt the short message according to the set order Encrypt the billing service content, the security serial number, the application version identifier, and the random number to obtain second security check information; compare the first security check information with the second security check information At the same time, billing is performed on the mobile terminal application. The embodiment of the present invention can ensure the billing safety of the short message in the stand-alone application downloaded from the application store.

The application relates to a train type identification method and system and a safety inspection method and system. The train type identification method according to the present disclosure includes using a line array camera that moves relative to the inspected train to continuously take pictures of the inspected train to generate multiple train sub-images, and splicing the multiple train sub-images to obtain the train of the inspected train image, extracting at least one train characteristic parameter from the train image, comparing the at least one train characteristic parameter with a pre-stored model template, and automatically determining the model of the inspected train according to the comparison result.

The invention provides an automobile speed determining method and device, and an automobile, and relates to the technical field of automobile control. The automobile speed determining method comprisesthe steps that the rotational speed of a motor of the automobile and the rotational speeds of a plurality of wheels are obtained in real time; if the current obtained rotational speeds of the multiple wheels are all within a first preset range, the first theoretical automobile speed is calculated according to the rotational speeds of the multiple wheels; if the current obtained rotational speed of the motor is within a second preset range, the second theoretical automobile speed is calculated according to the rotational speed of the motor; and the current output automobile speed of the automobile is determined according to the first theoretical automobile speed and the second theoretical automobile speed. According to the automobile speed determining method and device, and the automobile,the calculated theoretical automobile speeds are subjected to security checking, the possibility of accident occurring caused by automobile speed miscalculation due to unit exception is decreased, and the safety and reliability of the automobile are improved.

A sparse array three-dimensional imaging security inspection device and method, the present invention relates to a sparse array three-dimensional imaging security inspection device and method, which includes: a sparse antenna array, a radio frequency transceiver front end, a signal processing module, a display module and one or more manual processing seats . Under the control of the signal processing module, the position information of the human body is determined by rough scanning, and then according to the position information of the human body, the device is controlled by the signal processing module to enter the fine scanning mode. In the fine scanning mode, the signal processing module sends scanning instructions, and the RF transceiver front-end generates and transmits RF signals from the sparse antenna array. After the RF signal interacts with the target, the echo signal reflected by the target is received by the sparse antenna array and transmitted by the sparse antenna array. After the front-end processing of the radio frequency transceiver, it is transmitted to the signal processing module, and after analog-to-digital conversion in the signal processing module, and after calibration and imaging processing, the imaging processing results are sent to the detection module and the manual processing seat respectively. Finally, through the combination of automatic detection and manual processing of seats, it is determined whether the inspected person is carrying dangerous goods.
