Provided is an intelligent transport and detection electronic label with relay protection, comprising a casing. One side of the lower part of the casing is provided with a through hole. The internal part of the casing is provided with a swing motor, a second label shoe plate, a first pressure transducer, a second pressure transducer, and a control means. The second label shoe plate is disposed atone side of the through hole. The side part of the second label shoe plate is provided with a plurality of second strip-packed adhesive stickers arranged in one row. An output shaft of the swing motoris provided with a rotation rod, and the rotation rod is vertical to the output shaft of the swing motor. The first label shoe plate and the second label shoe plate can be respectively adhered to different relay labels. When it is required to replace a relay label, the relay label can be rapidly replaced by controlling the rotation of the swing motor, and thereby the trouble of manually scrapingthe relay label down can be avoided. The invention is advantageous in that the rotation rod is hinged to the upper part of the first label shoe plate, and when the rotation rod is driven by the swingmotor to rotate, the first label shoe plate will move downwardly to block the second label shoe plate, and thereby label replacing can be realized.
