This application discloses a wireless low-frequency communication method and a wireless low-frequency communication system. The wireless low-frequency communication method includes: a first low-frequency communication terminal modulates a first carrier signal loaded with first data into a first low-frequency signal and sends the first low-frequency signal to a second low-frequency communication terminal. The first data refers to instruction data issued by a user. When receiving the first low-frequency signal, the second low-frequency communication terminal demodulates the first low-frequency signal into the first carrier signal and analyzes the first carrier signal to obtain the first data. Communication is carried out through wireless low-frequency signals penetrating metal shields. Communication signals can be strengthened while communication distances can be increased with the metal shields. This application solves the problems of weak communication signals and short communication distances caused by wireless high-frequency signals failing to penetrate a sensor or a roaster device.

An object of the invention is to improve communication quality in a power storage management system.

The above-mentioned problem may be solved by the following one solution. When a communication error where transmission, reception, or both transmission and reception of a signal is not allowed occurs between one or a plurality of a plurality of information acquisition devices that acquires states of a plurality of power storage cells and an information collection device that communicates with the plurality of information acquisition devices in a time-division manner, and collects information related to the states of the plurality of power storage cells acquired by the plurality of respective information acquisition devices, a process for resolving a communication error is executed by putting all the plurality of information acquisition devices in a state in which communication with the information collection device is allowed at all times. Here, the plurality of information acquisition devices is in a state in which communication with the information collection device is allowed in a first period in which the plurality of information acquisition devices communicates with the information collection device, and is in a state in which the state, in which communication with the information collection device is allowed, is canceled in a second period in which other information acquisition devices communicate with the information collection device in a relation of n to 1 (n is a positive natural number indicating the number of communication channels of the information collection device).

A method and system for the post-adjustment (i.e., offline) of event timestamps to implement virtual time synchronization amongst detection node clocks. In existing methodologies with the goal of clock synchronization, clocks (and timestamps generated therefrom) are disciplined or adjusted at the recordation time of the events on a detection node (e.g., a switch/router, an Internet-of-Things (IoT) device, a wireless sensor, etc.). However, there is no particular reason for these clocks or timestamps to be accurate during the recordation time, but rather, should be accurate at their use or interpretation time. Further, through these recordation time adjustments, clock drifts and timing errors may be gradually introduced, leading to runaway inaccuracies. The disclosed method and system intentionally avoids the disciplining of clocks at event recordation times on the detection node and, instead, adjusts timestamps during interpretation times, to overcome the aforementioned issues.

The automated remote reading of fluid meters implemented in a system includes fluid meters, each measuring a consumption of fluids, and at least one gateway. Each gateway can exchange frames in accordance with a wireless communication standard with a plurality of meters via a first communication network, and to communicate with a management entity responsible for processing, in a centralised manner, information representing a consumption of fluids, referred to as readings, coming from meters via a second network. The method comprises for each gateway: defining meter reading periods for a set of meters paired with said gateway, the gateway being on standby outside each period and awake during each period; successively interrogating each meter in said set during each period in order to obtain a reading, each meter waking up at the start time of each period and going on standby as soon as it has transmitted a reading.

The present disclosure relates to the field of food chain monitoring at a plurality of situations and more particularly to a system and method for remotely monitoring of atmospheric conditions of one or more products. The remote monitoring system may comprise a data logger, a data collector, and an industrial tablet. The data logger may be enabled to log atmospheric data of the products present in a container and further send the atmospheric data to the data collector through data packet channels. The system may be further enabled for providing unique time slot to each data logger for sending the data packets without collision. The system may be further enabled with re-synchronisation methods for updating and synchronising the time of each data logger to avoid collision of two or more advertising packets.
