Reception level acquisition system for FSK wireless transceiver circuit and method thereof

Abstract

The invention provides a reception level acquisition system for an FSK (frequency-shift keying) wireless transceiver circuit and a method thereof, and relates to a reception level acquisition technology. The method comprises the following steps: (1) a master machine device and a slave machine device form a two-way simplex communication system; the master machine device actively makes a call, the slave machine device answers a message after receiving the call from the master machine device, and then the master machine device receives the answered message and then completes one-time transceiver communication; (2) for a plurality of the slave machine devices, the master machine device sequentially carries out transceiver communication with the slave machine devices; and (3) when the master machine device carries out transceiver communication with the slave machine devices, the master machine device and the slave machine devices acquire FSK reception level. The invention can be applied to a short-distance wireless transceiver and a middle and long-distance mobile communication optical fiber relay system for acquiring the FSK reception level as the monitoring quantity of the working condition of the FSK transceiver circuit.

Description

technical field

[0001] The invention relates to a receiving level acquisition technology, in particular to an FSK (Frequency-shift keying, frequency-shift keying) wireless transceiver circuit receiving level acquisition system and method thereof. Background technique

[0002] FSK wireless communication circuits have been widely used in short-distance wireless transceivers, and can also be matched with photoelectric conversion circuits to realize medium and long-distance transceiver communications; the mobile communication optical fiber relay system uses this method to realize the monitoring data transmission of near and far terminals and communication. Regardless of short-distance FSK wireless transceivers or medium- and long-distance FSK communication links, it is necessary to collect the receiving level of the FSK communication circuit, monitor the state changes of the communication link, and then judge whether the communication link is normal.
