Problems solved by technology

[0003] FSK codec radios are widely used in agricultural and pastoral areas and forest areas where these facilities are relatively simple, which is convenient for receiving weather warning information and is widely used. However, for SK codec radios in the prior art, herdsmen or other users need to use The radio can be carried with you to receive information immediately. For people at work, they hope to have a device that is more convenient to carry with them to listen to early warning information in real time.

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with preferred embodiments. The present invention provides a kind of meteorological early warning radio 100 that adopts FSK encoding and decoding, such as figure 1 As shown, it includes a first arc-shaped receiver body 110 and a second arc-shaped receiver body 120, the two sides of the first arc-shaped radio body 110 and the two sides of the second arc-shaped receiver body 120 pass through the first arc-shaped receiver body 120 respectively. The elastic part 130 is connected with the second elastic part 140, so that the first curved radio body 110 and the second curved radio body 120 form a body that can be worn on the arm through the first elastic part 130 and the second elastic part 140. Arm ring weather warning radio 100.

[0025] In a preferred embodiment of the patent of the present invention, the first curved radio body 110, such as figure 2 As shown, it includes a first arc-shaped o...

Abstract

The invention discloses a weather early-warning radio adopting FSK coding and decoding. The radio comprises a third arc-shaped body. The third arc-shaped body comprises a fifth arc-shaped outer wall and a sixth arc-shaped outer wall which are opposite. The fifth arc-shaped outer wall and the sixth arc-shaped outer wall are connected through a fifth annular bottom cover and a sixth annular top cover to form a radio containing body. The radio containing body comprises a battery bin. A bulb is arranged on the outer wall of a third elastic part. The third elastic part is fixedly and electrically connected with the third arc-shaped body. According to the weather early-warning radio adopting FSK coding and decoding, the radio is arranged to be in an arm ring style, so that carrying is convenient, and grazing and other work will not be affected while the radio is carried; furthermore, a control button is arranged on the outer wall of a radio body, so that operation is convenient.

Description

technical field [0001] The invention relates to a radio, in particular to a weather early warning radio adopting FSK coding and decoding. Background technique [0002] At present, data transmission generally adopts broadband wired or wireless transmission, such as QPSK modulation and demodulation often used in satellite transmission. Digital signal transmission can be realized with QAM, BPSK and QPSK modulation and demodulation technologies, but these technologies are more complicated and costly, and are mainly used in the fields of digital cable TV, 3G transmission and satellite transmission. In narrowband data transmission, such as low-frequency wireless transmission in the voice field, the loss is large and the bit error rate is high. The radio signal of the radio station is a narrowband, high bit error rate wireless transmission signal. The modulation and demodulation technology of ASM amplitude modulation and FM frequency modulation adopted by the existing radio stati...
