Estimating the term…
The invention refers to wireless safety systems and it relates to a method for transmitting data by a sensor of a wireless safety system that enables to transmit massive data to large distances (up to 2000 m). A method for transmitting data by a sensor of a wireless safety system that comprises at least one sensor and a receiver, which are coupled by means of a radio communication, is proposed. The method comprises: continuously exchanging data and/or data announcements, which are transmitted, by sending statuses and/or alarm signals through a main radio channel between the sensor and the receiver that is equipped with at least two radio modules, which are configured to perform the continuous data exchange, and activating a separate data channel for the data transmission using one of the radio modules that is not used for the main radio channel, and with a decision making unit. Wherein the sensor, through said main radio channel by means of the alarm signal (“Data Pending”), sends a request regarding a necessary data transmission through the separate data channel to the receiver, by means of the decision making unit, the receiver sends the corresponding signals to the sensor. After the signal regarding the beginning of the data transmission is received, the sensor begins to transmit the data through the data channel with a continuous series of the data packets. At the end of the data transmission the receiver sends the request with a control number of packets to confirm a completeness of the data transmission. After the control number of the packets and the fact that the data has been completely transmitted from the sensor are confirmed, the data channel is emptied for a next session of the data transmission, and the sensor, after the data transmission session is completed, switches to operation through the main radio channel. Also, a wireless safety system for implementation of the described method is proposed.
A method for transmitting data by a sensor of a wireless safety system that comprises at least one sensor and a receiver, which are coupled by means of a radio communication, the method comprising:
A wireless safety system that comprises a receiver and at least one sensor with a main radio channel with TDMA and a separate data channel between them, the data channel is configured to transmit data continuously, wherein said radio channels are distributed across frequencies, and the receiver comprises at least two radio modules, one of which is reserved only for creation of the separate data channel, and a decision making unit that is configured to control the data reception through the data channel.
