[0021] Such as Figure 1As shown in the figure, an Internet of Things intelligent lead seal includes a main body 1, a main board 2, a lead seal wire 3, and a fastener 4; a cavity is provided inside the main body 1, and the main board 2 is placed in the cavity; both ends of the lead seal wire 3 respectively pass through the fastener 4 and are connected to the main board 2 for power supply. The fastener 4 is arranged inside the inner cavity, and the fastener 4 enables the lead seal wire 3 to move in only one direction and not in two directions; through holes are respectively provided on both sides of the main body 1, and both ends of the lead seal wire 3 are respectively inserted into the through holes. The lead seal wire 3 passes out from one through hole, then the lead seal wire 3 is sleeved on the object to be sealed, and then passes into the other through hole, so that after the main board 2 is powered on, the object to be sealed is sealed. An insulating layer is provided on the part of the lead seal wire 3 in contact with the object to be sealed to prevent the lead seal wire 3 from forming a circuit with the object to be sealed. The part of the lead seal wire 3 in contact with the main board 2 has no insulating layer to facilitate forming a circuit with the main board 2.
[0022] As Figure 2 and Figure 3 shown in the figure, the main body 1 includes an upper cover 11 and a bottom cover 12, and the upper cover 11 and the bottom cover 12 are connected by bolts; a sealing strip 13 for sealing is provided between the upper cover 11 and the bottom cover 12. The sealing strip 13 is fitted between the upper cover 11 and the bottom cover 12 to prevent impurities such as dust or water from entering the cavity of the main body 1 and affecting the service life of the main board 2.
[0023] As Figure 4 shown in the figure, the upper cover 11 is provided with a first fixing groove 111 and a second fixing groove 112. The first fixing groove 111 is located above the second fixing groove 112; the first fixing groove 111 is oval-shaped, and a display cover 113 adapted to the first fixing groove 111 is arranged in the first fixing groove 111. The display cover 113 has a connecting bolt, and bolt holes are provided on both sides of the first fixing groove 111. The connecting bolt is adapted to the bolt holes to detachably fix the display cover 113 in the first fixing groove 111; the second fixing groove 112 is square-shaped, and an identification cover 114 adapted to the second fixing groove 112 is arranged in the second fixing groove 112. The identification cover 114 is in clearance fit in the second fixing groove 112, and an identification code is pasted on the identification cover 114. The identification code is used to identify the number of the lead seal and determine the position of the lead seal.
[0024] Upper fixing parts 115 are respectively provided on the left and right sides of the upper cover 11, and lower fixing parts 116 adapted to the upper fixing parts 115 are respectively provided on the left and right sides of the bottom cover 12. The fastener 4 is located between the upper fixing part 115 and the lower fixing part 116. Two fasteners 4 are respectively placed between the corresponding upper fixing part 115 and lower fixing part 116 to effectively limit the movement of the lead seal wire 3.
[0025] The main board 2 is connected to a power supply 21, and a daughter board 22 is arranged on the main board 2; an information transmission module 23, a display module 24 and a wake-up module 25 are arranged on the main board 2. The display module 24 is used to detect the state of the seal wire 3 and can obtain the state information of the seal wire 3 from the display cover 113. When the loop formed by the seal wire 3 is normal, the information transmission module 23 will transmit the information to the receiving end, proving that the sealed object has not been opened. If the seal wire 3 is violently damaged, the information transmission module 23 will transmit the short-circuit information to the receiving end, proving that the sealed object has been opened. A keyhole 117 is arranged on the upper cover 11, and a wake-up button 118 is arranged in the keyhole 117. The wake-up button 118 is adapted to the wake-up module 25. When the seal device is placed for a long time, it will be in a sleep state to save resources. When the seal wire 3 is violently damaged, the seal device will be activated. When manual operation of the seal device is required, the wake-up button 118 needs to be used to wake up the seal device.
[0026] A plurality of bolt holes 121 are symmetrically arranged on the left and right of the bottom cover 12. Connecting holes adapted to the bolt holes 121 are arranged on the upper cover 11, and nuts 123 adapted to the bolts 124 are arranged in the connecting holes. The bolts 124 pass through the bolt holes 121 and the nuts 123 on the connecting holes to connect, so that the upper cover 11 and the bottom cover 12 are bolt-connected. A tension sensor is arranged in the cavity of the main body 1. The tension sensor is connected to the seal wire 3. The tension sensor effectively ensures that the seal wire 3 is in a taut state. If the seal wire 3 is violently damaged, the seal wire 3 will bounce off under the action of tension, and the short-circuit operation difficulty coefficient is very large and basically impossible to complete, effectively preventing short-circuiting. If the seal wire 3 is too long and the tension of the seal wire 3 is not large enough, it provides convenience for short-circuit operation, resulting in the problem that the sealed object can be opened but the signal of being opened cannot be received.
[0027] Working principle:
[0028] One end of the seal wire 3 enters the cavity of the main body 1 from one of its through holes, and passes through the fastener 4 to connect the seal wire 3 to the main board 2 and contact the main board 2. The other end of the seal wire 3 passes through the object to be sealed and then enters the cavity of the main body 1 from the other through hole, and also passes through the fastener 4 to connect the seal wire 3 to the main board 2 and contact the main board 2, thus forming an electric current loop. After the tension sensor makes the tension of the seal wire 3 reach the target value, the power supply 21 is started to energize the main board 2 to form an electric current loop, completing the sealing operation.
[0029] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
