The present invention provides a method, apparatus and system for transmitting and receiving a client signal. The method for transmitting a client signal includes, at the transmitting end, mapping a client signal to be transmitted to a corresponding low-order Optical Channel Data Unit (ODU) in a low-order ODU set, wherein low-order ODUs in the low-order ODU set having rates increased in order, and having rate correspondence relations with the client signals; mapping the low-order ODU to a timeslot of a high-order Optical Channel Payload Unit (OPU) in a high-order OPU set; and adding overheads to the high-order OPU to form an Optical Channel Transport Unit (OTU), and transferring the OTU to an Optical Transport Network (OTN) for transmission.

The invention discloses a construction environment monitoring system and monitoring method based on big data, belonging to the technical field of environmental protection monitoring. The system includes a data acquisition module, a wireless transceiver module, a data transmission module, a main controller, an early warning module, a display module and a power supply module , database and information monitoring platform; monitoring methods include registering and recording information on all monitoring points; using wireless data transmission for remote data transmission; entering data with normal dust particle concentration into the normal information database; Data processing; manual review of results to ensure the authenticity of the results. The construction environment monitoring system of the present invention obtains the construction dust concentration in different construction stages, grasps the dust pollution situation and emission characteristics in different processes, provides data support for further research on the diffusion law of construction dust on construction sites, and can also strengthen the dust on the construction site. Pollution Prevention and Control.

The invention discloses a system used for test paper management by applying radio frequency identification technology and a method thereof. The system consists of a central control server used for treating and storing input information, a reading and writing device used for reading and writing code information of a wireless radio frequency automatic identification label that is stick on the test papers and a switch control module used for obtaining unlocking code of reading people or reviewers of the test papers. Compared with the prior art, the radio frequency identification technology applied in the test paper management system of the invention can record every link of circulation management of the test papers timely and automatically so as to realize tracking management of the test papers and provide powerful management against man-made actions of surreptitious change, modification, etc., during paper reviewing at the same time by using the code information of the wireless radio frequency automatic identification label.

The invention discloses a distributed access control model and access method. The access control subject sends access request information, and the neighbor nodes of the access control subject judge whether they are the access control object according to the access request information; if so, judge the access control subject's Whether the access request complies with its own access control strategy, if so, provide corresponding access content and operations; The control strategy judges whether the access control subject in this access request has permission to access the access control object in this access request; if it has permission, it forwards the access request to its neighbor nodes and repeats the above operations; if not, then Return a rejection message. The access control strategy of the present invention adopts a distributed management method, so that each node in the network that has an access relationship with it jointly manages the access control strategy of the entire network.

The invention discloses a static switch and a control method applied to a connection of a microgrid and a public supply network. The static switch and the control method applied to the connection of the microgrid and the public supply network are characterized by comprising a main circuit and a controller, wherein the main circuit is placed between the public supply network and the microgrid, the controller controls the main circuit to turn on and turn off, and on-grid and off-grid of the microgrid are achieved through the power on and power off of the main circuit. Voltage, frequency and phase position of the public supply network and the microgrid and currents flowing past a bypass circuit are sampled by the controller to acquire a sampling signal, the power on or power off of the instruct main circuit are judged to achieve the on-grid and off-grid of the microgrid through calculation. According to the static switch and the control method applied to the connection of the microgrid and the public supply network, full automatic control on the smooth on-grid and off-grid of the microgrid is achieved, a micro source inverter of the microgrid can be monitored and controlled by the controller, and the purpose of energy management of the microgrid or assisting an upper level device to achieve energy management of the microgrid is achieved.

The invention discloses a business interface management method, device, storage medium, and terminal, and relates to the field of communication technology. The business code of the APP interface is numerous and messy. Including: when the service controller receives the service processing request sent by the APP interface, extract the configuration information to be initialized corresponding to the service to be processed requested by the service processing request in the configuration file; Configure the initialization parameters and business information initialization configuration information; the service controller sends the initialized configuration information to the service class of the service controller; the service class of the service controller parses the business processing request type in the configuration information, and proceeds according to the parsed type Business processing; the service class of the service controller feeds back the processing results to the APP interface through the service controller.

The invention belongs to the field of radar target echo simulation of radar simulation test equipment, and specifically relates to a pulse compression radar dense target simulation method based on frequency-domain matched filtering. Through a dense target real-time simulation method, a standard multi-target signal can be generated flexibly with fewer device logic resources to test the multi-target detection resolution precision of radar, a flaky clutter target signal based on dense targets can be generated in a simulated manner to detect the anti-clutter detection ability of radar in signal processing, and a smart noise jamming signal based on dense targets can be generated in a simulated manner to detect the anti-smart-noise-jamming ability of radar in signal processing.
