according to the article turnover mode of the political system, the robot automatically transports in the whole process according to the electronic tag information, so that case-irrelevant personnel are prevented from touching case-involved articles, meanwhile, the system also relates to information encryption and data validity check links in the tag information writing process, and non-case-involved prison managers cannot obtain tag information plaintexts, so that illegal information writing is avoided;
meanwhile, the defects that if an RFID label and a two-dimensional code label are adopted, the label is easily stained, so that the identification is difficult, the data verification cannot be carried out, and the data is easily tampered can be effectively overcome; the identity of the turnover basket is identified by adopting a two-dimensional code mode, the installation of two-dimensional code scanning identification equipment on a robot structure is difficult, the requirement on illumination light of an identifier is high, the batch scanning identification speed is slow, and especially when the turnover basket is placed on a material box rack of a robot body, the turnover basket needs to be respectively identified by one basket scanning code; in addition, the mechanical arm of the robot can simultaneously clamp a plurality of turnover baskets at one time and also can quickly identify the identities of the turnover baskets in the clamping process, and the two-dimension code identification cannot simultaneously identify 2 two-dimension code identities and cannot meet the requirements of use scenes.
Meanwhile, the robot body of the system also sends a query instruction to the bus polling through the CAN bus period until an electronic tag responds; the robot body actively sends the identity information of the robot body to the electronic tag through the CAN bus, the electronic tag verifies whether the identity ID of the robot is consistent with the robot ID information stored in the FLASH of the MCU main control chip or not, if so, a destination address is sent to the robot, and the robot receives the destination address information and then sends the turnover box to a specified destination; if the difference is not consistent, controlling an electronic tag buzzer to alarm, and not sending a destination address to the robot so as to prevent the problem of material evidence article turnover error;
the problem that the prison management has a leak and is lost management and is not under inspection due to the fact that the personnel who work and want to attend the prison transfer articles and ventilate and report letters to the suspect by using the working convenience is effectively solved.
