The present application provides an array-type image detection device, including two columns of imaging arrays arranged at intervals along a first direction, each column of the imaging array includes a plurality of imaging modules arranged at intervals along a second direction, each imaging module includes a magnifying lens and an imaging chip arranged in sequence along its optical axis; each imaging module magnifies the image to be detected located in its detection area and images it in its imaging area and is acquired by the imaging chip located in its imaging area; and except for the detection areas located at the head and tail sides of the second direction, each detection area has overlapping parts with other detection areas at both ends along the second direction. The array-type image detection device provided by the present application can effectively solve the problems of low resolution of existing contact image sensors, difficulty in detecting high-resolution images, and detection blind spots when performing magnified detection, and can obtain a clear magnified image of the image to be detected within the full-frame range.

The invention discloses a data storage method and system for a storage chip, and the method comprises the steps: selecting reference data and sample data from target storage data, and carrying out the analysis, and obtaining a data similarity value; the data similarity value is compared with a data similarity threshold value, and if the data similarity value is larger than or equal to the data similarity threshold value, the reference data and the sample data are classified into the same classification data set; obtaining a residual storage space, judging whether the residual storage space is smaller than a residual storage space threshold value or not, and if yes, analyzing data in the classified data set to obtain a data set key value; identifying the non-key data group to generate a compression optimization signal; based on the compression optimization signal, judging whether the residual storage space of the system is smaller than a residual storage space threshold after compression processing, and if yes, analyzing the non-high access frequency data to obtain a compression priority value; and performing optimization compression on the non-high access frequency data according to the compression priority value.

The invention discloses an air-situation fusion data recording and playback system and a playback method thereof. The air-situation fusion data recording and playback system comprises a data recording module, a data analysis module and a data visual display module. The method comprises the following steps: firstly, embedding a data recording module into an air-situation fusion system through an interface, acquiring key data in the system through a data recording interface in the working process of the system, and recording the data according to a preset rule to form a data file; secondly, the data analysis module operates file pointers of data files recorded in the system process according to a data recording rule to perform data offset so as to realize data anti-translation; and finally, the visual display module carries out time registration on the read data and then carries out visual playback display. According to the method, comprehensive analysis, recording and objective and real reproduction of the air situation information in the multi-source radar system and the fusion situation of the air situation information are achieved, a new thought is provided for data recording and playback of the multi-source radar air situation fusion system, reusability is high, and expandability is high.

The application relates to a construction site safety management method and system, an access control system and a safety helmet, and belongs to the field of engineering construction. After a construction personnel issues an access request to an access control system of a construction site, the access control system cooperates with the safety helmet of the construction personnel to understand the current wearing condition of the protective tool of the construction personnel, and processes the access request of the construction personnel based on the wearing condition of the protective tool, so that the construction personnel who do not wear the protective tool in a qualified manner can be prevented from entering the construction site, and in turn, the safety hazards caused by the non-compliance of the wearing of the protective tool can be reduced. Moreover, the safety helmet is the most basic and common protective tool, a radio frequency card reader is arranged on the safety helmet, the construction personnel do not need to carry an independent radio frequency card reader, the burden of the construction personnel is reduced, and the radio frequency card reader can also ensure that the radio frequency tags on other protective tools worn by the construction personnel can be normally read.
