Image forming device and safety control system

Abstract

The invention provides an image forming device and a safety control system thereof. The safety control system comprises a first control system and a second control system. The first control system comprises a safety module, and the safety module is configured to perform safety supervision on information of the image forming device; the second control system is configured to control the image forming device to execute imaging operation; the first control system is in communication connection with the terminal equipment, the first control system is further electrically connected with the secondcontrol system; and when the image forming device transmits data to the terminal equipment, if the communication connection between the first control system and the terminal equipment is disconnected,the first control system firstly controls the second control system to be closed, then, the first control system is automatically restarted, and the second control system is controlled to be started.According to the image forming device, when the communication connection between the first control system and the terminal equipment is disconnected, the first control system can firstly control thesecond control system to be closed and then automatically restarts, and can control the second control system to be started.

Description

【Technical field】 [0001] The invention relates to the technical field of image formation, in particular to an image forming device and a safety control system. 【Background technique】 [0002] With the development of imaging technology, more and more image forming devices are used in office and daily life. Common image forming devices include but are not limited to printers, copiers, scanners, fax machines or integrated printing, copying, scanning, and fax functions. One or more multifunctional business machines. In the prior art, printing information security has become important, so image forming apparatuses are supporting security-related functions such as developing a control system (for example, SoC (System on Chip) loaded with firmware , system on a chip)) controls the data input and output of the image forming device, but the control system in the existing image forming device needs to control the engine mechanism of the image forming device in addition to controlling...

Problems solved by technology

However, there is a problem with this image forming device. If the first control system detects that the USB data line between the image forming device and the PC is disconnected during the process of transmitting the scan data to the PC, the first control system needs to send the second data to the second PC. The control system informs it that the USB communication with the PC end is disconnected, but because the time when the second control system obtains the information is not at the same time as the time when the USB cable between the first control system and the PC end is disconnected, it may not be possible Stop transmitting data in time, so that system failure may occur, and the user needs to manually restart the image forming device, which is troublesome
