Abstract:
1. A method for identifying pulse optical signal, comprising performing the following steps by a hardware processor: A. receiving first trigger information and deleting data in a storage area; B. in response to the first trigger information, collecting and identifying a pulse optical signal with a predetermined method to obtain a unit of data; C. parsing the unit of data and determining type of the unit of data; if the unit of data is unit of data representing header information, performing D; if the unit of data is other type of unit of data, performing E; D. setting a corresponding packet header id for the unit of data and going back to B; E. determining whether the unit of data matches the currently-set packet header id; if yes, performing F; if no, discarding the unit of data and going back to B; F. determining whether there is unreceived unit of data corresponding to the currently set packet header id; if yes, going back to B, if no, performing G; G. packeting the unit of data represented by the currently-set packet header id and all units of data corresponding to the currently-set packet header id to obtain a group of data packets; wherein the predetermined method comprises: B1. identifying the pulse optical signal collected at the same time with a predetermined receiving method to obtain at least one bit of information and taking the at least one bit of information as one bit of information group; B2. determining whether the obtained at least one bit of information group constitutes one unit of data, if yes, combining the obtained at least one bit of information group to obtain a unit of data; if no, going back to B1.
