The invention discloses a method for converting data format between IP data packages on a CAN bus and CAN messages, comprising the steps of: (1) virtualizing a CAN interface: while registering a CAN device in a system, registering according to the standard format of a registered Ethernet interface; while defining an input/output interface module, using a custom IPoverCAN processing interface for interacting with a network layer and the CAN device; and (2) sending IP messages and receiving CAN messages: while sending IP messages, invoking a Socket interface used by the Ethernet interface, and invoking to an IPoverCAN module after invoking layer by layer by the system; while receiving the CAN messages, placing the CAN messages from the same source address in the same IP packet buffering area, and submitting to an upper layer until a complete IP packet is assembled. In the invention, a hardware structure is simplified, the application range is expanded, and the upper layer application is wider so that the processing of data and application programming by the upper layer is convenient by abstracting the CAN device to be an Ethernet interface.

A differential pulse detecting apparatus for terahertz wave time domain information and a differential pulse detecting method are provided. The apparatus includes a femtosecond laser generating unit with a certain repetition frequency, a beam splitting unit, a terahertz pulse generating unit, a unit containing a sample to be detected, a terahertz pulse collecting unit, a detecting laser pulse focusing unit, a detecting unit, a spatial light modulation unit and a terahertz pulse reduction unit. As the spatial light modulation unit can regulate the spatial optical path difference between a terahertz pulse and a detecting laser pulse, the difference between the terahertz pulse and the detecting laser pulse simultaneously reaching the detecting unit is an integral multiple of an adjacent pulse interval, and therefore the method can regulate the optical path difference in real time according to the size of a detected object under a condition that a whole optical path system is determined, a design of the overall system is not limited to the size of the detected object, and limitation of traditional terahertz time-domain spectroscopy systems on the size of the detected object is got rid of.

The invention discloses an illumination device. Laser light is adopted for irradiating any one wavelength conversion area, obtained stimulated light is reflected by a corresponding reflective cover to be emitted in the set direction, and it is ensured that the emitted light brightness of the illumination device is high due to the fact that a laser light source is high in brightness. Meanwhile, the illumination device is simple in structure, all components of the device are limited in size, and therefore it is ensured that the illumination device is small in size. By means of the semi-airtight fixing way of each reflective cover and a first substrate, it is ensured that simulated light is completely emitted, and light waste is avoided. A control device controls a wavelength conversion device to switch different wavelength conversion areas for receiving laser light, and therefore different light emitting effects of the illumination device are achieved. By optimizing the parameters such as light spots of second simulated light transmitted by the wavelength conversion device and first simulated light reflected by the wavelength conversion device, the different light emitting effects of the illumination device are further achieved, and then applicability and flexibility of the illumination device are improved.
