The invention discloses a digital multimeter display method based on a double-ARM processor platform. Comprising the following steps: receiving a digital display signal and a digital display instruction from an ARM processor in a double-ARM processor platform; driving the digital multimeter to display data based on the digital display signal and the digital display instruction; wherein the main ARM processor controls the simulation conditioning acquisition unit to execute a measurement task based on a remote command; the main ARM processor communicates with the slave ARM processor through an LAN interface, and the main ARM processor is physically isolated from the slave ARM processor; and the slave ARM processor drives the digital multimeter to display data based on the digital display signal and the digital display instruction, and the slave ARM processor is also used for executing a digital task. According to the invention, low power consumption, high integration, flexible division of labor and low cost are realized while the performance is ensured to meet the measurement requirement.

The application provides a false news identification method based on text and image multi-scale features and background knowledge, which fully and effectively extracts news content from three aspects of news text features, news image features and news background knowledge features, compares the extracted text features and image features through a comparison network to obtain a comparison result of multi-scale text and image features, compares the background knowledge and the news text to obtain a comparison result of the news and the background knowledge, finally performs cross-modal fusion on the two comparison results and the news text features, and sends the fusion result to a true and false identifier, so that the true and false of the news is identified. The method can effectively improve the accuracy and robustness of false news detection.
