The invention especially refers to the technology that the end customer can previously do the actual test and quality control to test whether the electronic seal is functioning normally by using the mobile phone, so that it can be used in a discarding manner.
The prior art is as shown by the inventor's approved patents U.S. Ser. No. 08/558,700B2, U.S. Ser. No. 08/866,609B2, and U.S. Ser. No. 09/508,271B2; however, after being reflected by the customer, since the spring is formed in one-piece in the lock-seat in those previous patents and in order to maintain the strength of the spring structure, the spring activity margin is not large. But, there is a tolerance when the circuit board is mounted on the plug-bolt and there is also a tolerance when the plug-bolt is engaged, lock and positioned in the lock-seat; it is inevitable that there will be the defective products in which the cumulative tolerance affects the spring activity margin. The result is that the plug-bolt and the lock-seat are manufactured separately and their quality controls are met; however, when the end customer engages and locks the plug-bolt and the lock-seat with each other to use it as a cargo-container seal, the signal will be invalid or the read rate will be deteriorated and the expected function of supervision will be lost, but the end customer cannot know from the actual test.
The main content of the present invention is that the circuit board of the electronic seal is provided with a chip, a main circuit, and a secondary circuit, wherein the secondary circuit is matched with a detection antenna.
And, when the plug-bolt and the lock-seat are used in engaging and locking; the main circuit, the chip, and the main antenna of the lock-seat are electrically connected to emit a first signal for providing the identification host to monitor, and controlling the secondary circuit to be electrically connected with the chip and the detection antenna to emit a second signal. The second signal can be used for the mobile phone software to do the quality control of the first signal to decide whether operating normally or not, and the first signal and the second signal can be cut-off simultaneously when the plug-bolt is broken. This can allow the end customer to do the actual test and quality control using the mobile phone, thus avoiding the use of defective products.
The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following detailed description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
The foregoing and other aspects, features, and utilities of the present invention will be best understood from the following detailed description of the preferred embodiments when read in conjunction with the accompanying drawings.

The bolt-piece 10 is made of a metal material of a relatively strong structure, which has a rod-body 11, a cap-head 12 radially and outwardly extending from the top end of the rod-body 11, and an accommodating-hole 13 penetrating through the top surface and the bottom surface; wherein the bolt-piece 10 is further recessedly set with an engaging-fit configuration 14 on the lower outer circumference ring. The circuit board 20 has a neck-shrinking section 201 that can be inserted into the accommodating-hole 13 from top to bottom, and an external-expansion section 202 is defined above the neck-shrinking section 201; which the bottom end of the external-expansion section 202 can be positioned on the cap-head 12 to make the neck-shrinking section 201 able to be suspended in the accommodating-hole 13. The circuit board 20 is further distributedly set with a main circuit 21 on the front surface of the neck-shrinking section 201 and is distributedly set with a secondary circuit 22 on the back surface, so that the main circuit 21 and the secondary circuit 22 can be distributedly set in a wide range on the upside and downside of the neck-shrinking section 201 and can be kept non-conducted with each other. Wherein, the main circuit 21 at least comprises a lower-contact point 211 set at the bottom surface of the neck-shrinking section 201, a starting point 212 set at the top edge of the neck-shrinking section 201, and an ending point 213 set at the top edge of the neck-shrinking section 201; as for the secondary circuit 22, it comprises a beginning point 221 and an terminal point 222 set at the top edge of the upside of the neck-shrinking section 201; therefore a chip 23 can be enabled to mount among the starting point 212, the ending point 213, the beginning point 221, and the terminal point 222. Wherein the chip 23 and the main circuit 21 can emit an RFID frequency band or a microwave frequency band; wherein the chip 23 and the secondary circuit 22 can emit a magnetic field frequency band which can provide a mobile phone software to do the quality control, and the magnetic field frequency band can be adopted by an NFC system or an LF system; in other words, the chip 23 is a system chip and has the pins which can emit at least two different frequency bands; and the pins correspond and connect with the starting point 212, the ending point 213, the beginning point 221, and the terminal point 222. The surface of the external-expansion section 202 is set with a detection antenna 24 in a spiral shape, and the detection antenna 24 is matched with the secondary circuit 22 and the chip 23 through the beginning point 221 and the terminal point 222 to form a closed-loop, wherein the closed-circuit shown in the figure is selected a serial connection. The top edge of the external-expansion section 202 is set with a startup unit 25, and the startup unit 25 can adopt a micro-motion type switch as shown in the figure; which the startup unit 25 can disconnect the detection antenna 24 and the secondary circuit 22. Additionally, the external-expansion section 202 and the outer periphery of the cap-head 12 are wrapped and covered with a waterproof sleeve W as shown in

The first signal and the second signal can have the same serial number (identification code) built in, so that the mobile phone and the customs host can determine whether the cargo-containers indicated by the serial number are the same.
The present invention indeed has the following advantages:
