The invention belongs to the technical field of spaceflight, and discloses an adaptive rocket telemetry system and an implementation method thereof. The system comprises a communication front-end processor which is used for receiving rocket telemetry data and converting the rocket telemetry data into telemetry message information according to a user-defined application layer protocol; a communication center machine used for analyzing and processing the telemetry message information and storing the telemetry message information in a database in a classified manner; a Web server end which is connected with a database of the communication center machine; and a browser front end connected with the Web server end. According to the system, the information of different rocket models can be packaged into messages of a fixed format through a user-defined application layer protocol, the system can adapt to the different rocket models, the universality is high, the repeated development of a rocket system can be avoided, and the cost of the system is reduced.

An adaptive rocket telemetry system and an implementation method thereof

The invention provides a communication protocol for information interaction between an intelligent miniature circuit breaker and a control center. The communication protocol comprises a data structurewhich comprises a frame header, an address, a control code, a data length, a command code, data content, and a checksum. The control code comprises a frame type, and the frame type comprises a data frame foractively uploading heartbeat data, a data frame for copying and reading the data and a data frame for setting the data; the data frame foractively uploading heartbeat data is defined as a data frame actively sent by a circuit breaker and a data frame passively received by a control center, and is used for actively uploading data when the data is changed so as to reduce the burden of a server for querying the data; wherein the data frame for copying and reading the data is used for acquiring a command related to copying and reading data; the data frame for setting the data is used forsetting circuit breaker parameters and control states. According to the method, the real-time intelligent micro-break state can be obtained in time, meanwhile, the transmitted data size is effectively reduced, the transmitted data is more economical and effective, the burden of a server is reduced, and the construction cost and the operation cost are reduced.

The invention relates to a large data volume concurrent access method based on a real-time database and electronic equipment, which are applied to data communication in an intelligent building, the intelligent building comprises a plurality of hardware equipment, and the method comprises the following steps: establishing communication connection between the real-time database and the plurality ofhardware equipment; detecting whether data is collected or not; if yes, receiving a message uploaded by a plurality of hardware devices, wherein the message comprises running data in the running process of the hardware equipment; analyzing and processing the message to obtain operation data in one-to-one correspondence with the plurality of hardware devices; and performing conversion processing onthe operation data, and storing the operation data in a real-time database by adopting a preset storage method. According to the invention, real-time communication with a large amount of hardware equipment can be realized, data acquisition is completed, a real-time database is taken as a basis, a data acquisition and data storage mode is optimized, large amount of data interaction can be rapidlycompleted when a large amount of data is concurrently transmitted, and the requirement that a large amount of data needs to be interacted at the same time in an intelligent building is met.

Large data volume concurrent access method based on real-time database and electronic equipment

The present invention provides a telemetry data organization method and device for Internet of Things communication, and relates to the technical field of Internet of Things communications. The methodcomprises the following steps: collecting telemetry data information; generating a message according to the telemetry data information, wherein the data structure of the message comprises an information object address field, a parameter change indication field, and a change parameter data field; the information object address field is used for storing the address of a telemetry data information collection device; the parameter change indication field comprises a plurality of indication bits, and each parameter of the collection device corresponds to an indication bit; the indication bit is assigned according to whether the amount of change of the parameter in the current collection period is greater than a threshold value; the change parameter data field is used for storing data of the parameter whose amount of change is greater than the threshold value according to a preset order; and sending the message to a control end. The telemetry data organization method and device for the Internet of Things communication provided by the embodiment of the invention can improve the data transmission efficiency, alleviate the problems of data accumulation and high concurrency of the server.

Telemetry data organization method and device for Internet of Things communication

The invention relates to an IOT (Internet of Things) communication method and device, and relates to the technical field of IOT communication. The method comprises the steps: initializing reference data of a parameter of a collection device; acquiring real-time data of the parameter; calculating a change amount of the parameter according to the real-time data and the reference data; comparing thechange amount of the parameter with a preset change amount threshold value, and making the parameter whose amount of change is greater than the change amount threshold value as a first parameter; anduploading the real-time data corresponding to the first parameter. The IOT communication method and device provided by the embodiment of the present invention can improve data transmission efficiency,and solves the problems that the data accumulation, untimely transmission and excessive server-side processing pressure of an IOT gateway or a data collection terminal in mass data transmission.
