Provided are a forming terminal of a time slot data frame compatible with a data chain and a working method of the same. Based on correlation of data redundancy and requirements for communication quality of service, under the condition of constant radio-frequency bandwidth, the terminal can visually and clearly display the formation process of the time slot data frame through the coordination of parts. The received service data is analyzed, and an appropriate encoding, a modulation, a spread spectrum combined technology and a data encapsulation formats are selected, then the combined technical information is creatively mapped to a fine synchronization field stuffing bits for the time slot data frame, so that when the receiving terminal is in the fine synchronization, the encoding, the modulation and the spread spectrum subsequent combined technical information of the subsequent received data are obtained, which can shorten the preprocessing time of the received data, satisfy the requirement of anti-interference, confidentiality, real-time and coverage of the data chain, and further enhance the adaptability of the data chain to future complex environments and improve system throughput. The forming terminal of the time slot data frame compatible with the data chain has the advantages of being compact, reasonable and artful in structure, being simple, convenient and easy to operate, and being promising in application prospect.
