Indoor positioning method, device and system based on RFID (radio frequency identification)

The embodiment of the invention discloses an indoor positioning method, device and system based on RFID (radio frequency identification). The method comprises the following steps of controlling an RFID antenna to rotate at the preset angle; obtaining the rotating angle of the RFID antenna for rotating to the current position; scanning a label; obtaining the label signal intensity corresponding to the rotating angle; determining a first elliptic equation and a second elliptic equation corresponding to the label according to the rotating angle, the label signal intensity and the rotating antenna positioning algorithm; processing the first elliptic equation and the second elliptic equation according to the elliptic intersection point calculation algorithm to obtain the corresponding two elliptic intersection points; whether the distance between the intersection point and the origin is greater than the first preset distance or not; if so, the intersection point is output; otherwise, the rotating angle when the RFID antenna rotates to another position is continuously obtained, and the cyclic operation is performed until the final intersection point is obtained. The embodiment of the invention has the advantages that only one RFID antenna is used; the advantages of simple system structure, low cost, low deployment difficulty and high hardware utilization rate are realized.

Power inverter with functions of UPS (uninterrupted power supply) and active power filter

The invention relates to a power inverter with functions of a UPS (uninterrupted power supply) and an active power filter, belonging to the technical fields of power inverters. The power inverter comprises an active power filter a digital control circuit and further comprises a storage battery, wherein the storage battery and the digital control circuit are respectively electrically connected with the active power filter. The power inverter has the beneficial effects that the storage battery is parallel connected to the direct-current side of the main circuit of the active power filter, and when harmonic current and reactive compensation are finished, energy is stored for the storage battery, thus when malfunctions of power supply through the power grid voltage occurs, power can be supplied for the load by the storage battery through the inverter; through the control of the inverter, the additional UPS device is saved for the system, thus the device cost is lowered; and when power is supplied normally for the power supply, after certain voltage stabilization and filtering is carried out on the power supply by the UPS, power is sent to the load, thus an alternating-current power supply with better quality can be obtained for the load.

InactiveCN106131005AImprove hardware utilizationBroaden data service capabilitiesAdvertisingTransmissionThe InternetCrowds
The present invention provides an internet health detection system with an advertisement network function. The system comprises a communication network, a cloud platform, an advertisement push device, a health advertisement all-in-one machine, a mobile terminal and a big data server that are all communicated with the communication network. The big data server acquires a physical sign database for detection by the health advertisement all-in-one machine from the cloud platform through the communication network, analyzes the physical sign database, determines health defects or lesion existing in the physical sign database, and sends an advertisement push advise related to the defects or lesion to the advertisement push device. The advertisement push device pushes advertisement information suitable for watching by corresponding users to the health advertisement all-in-one machine to play. The mobile terminal is used for identity logging by the user, authenticating or acquiring the physical sign database. Through adoption of the system, a hardware use ratio of a traditional advertisement system is improved, a function of checking detection data and advertisement information remotely at any time is realized, advertisement display attention is increased, and a crowd effect is improved.

A method for enhanced self-adapted data retransfer

The invention discloses a method for retransmitting enhanced self-adaptive data. The method adopting a self-adaptation technique is: when a communication channel is in good condition, to code data by means of a high bit rate coder which has a high transmission rate and few redundant error-correcting codes and to complete initial transmission of the data, or to use a method of information bit puncturing hybrid retransmission of data for improving the utilization rate of hardware and the system throughput and saving energy; and when the communication channel is in poor condition, to code data by means of a low bit rate coder which has a high transmission rate and more redundant error-correcting codes and to complete initial transmission of the data, or to use a method of parity bit puncturing hybrid retransmission of data for guaranteeing the reliability of communication transmission. The method of the invention has the combined advantages of technologies of information bit puncturing hybrid retransmission and parity bit puncturing hybrid retransmission, and thus can not only improve the utilization rate of the hardware, reduce the time delay for transmission processing, improve thesystem throughput and saves energy, but also ensure good error-correcting transmission performance in poor communication channel condition.
