In this process, most RFID readers are used as intelligent logistics sorting systems to improve efficiency and ensure accuracy. Existing RFID readers, especially handheld RFID readers, if the distance between two handheld RFID readers is shortened, the signals of the two will interfere with each other, and the reading and writing of electronic tags will become weaker.

[0036] Reference Figure 1-Figure 5 As shown, an intelligent logistics distribution system based on the Internet of Things includes an RFID reader, a forklift, a robot, and a logistics vehicle, wherein the structure of the RFID reader includes:

[0037] A housing 5, wherein a radio frequency interface module 2 is provided on the front end surface of the housing 5, a voice announcer 3 is installed on the bottom surface of the housing 5 directly below the radio frequency interface module 2, and a handle 4 is installed on the rear end bottom surface of the housing 5, and the handle 4 and the voice announcer 3 are on the same horizontal line;

[0038] The reading and writing system 1 is housed inside the housing 5 and is connected to the infrared camera and the voice announcer 3;

[0039] The reading and writing system 1 comprises the following structure:

[0040] The integrated circuit board 12 is arranged in the middle of the inner bottom end surface of the housing 5, the front end of the integrated circuit board 12 is fixed to the inner front end of the housing 5 by the second fixed horizontal plate 14, and the rear end of the integrated circuit board 12 is fixed to the inner rear end of the housing 5 by the first fixed horizontal plate 10, the first fixed horizontal plate 10 and the second fixed horizontal plate 14 are parallel to each other, and the horizontal ends of the first fixed horizontal plate 10 and the second fixed horizontal plate 14 are fixed to the inner wall of the housing 5;

[0041] A filter 13, which is accommodated in the housing 5 between the front end of the integrated circuit board 12 and the radio frequency interface module 2, and the filter 13 is circuit-connected to the integrated circuit board 12 and the radio frequency interface module 2;

[0042] Anti-collision structure 11, the number of the anti-collision structure 11 is two groups, the two groups are respectively arranged on the left and right sides of the integrated circuit board 12, and the anti-collision structure 11 is movably connected to the integrated circuit board 12;

[0043] The anti-collision structure 11 includes the following structures:

[0044] The blocking bar 116 has a wavy top surface and a smooth bottom surface. The blocking bar 116 is installed in a recess 117 on the side of the soft panel 113 close to the integrated circuit board 12. When the integrated circuit board 12 is skewed due to a collision, it will gradually tilt toward the soft panel 113. Because the wavy top surface of the blocking bar 116 increases the difficulty of its movement, the buffering force is increased to prevent the integrated circuit board 12 from directly colliding with the inner surface of the shell 5 and causing damage. At the same time, the interface with the filter 13 is unstable, resulting in information deviation.

[0045] The soft panel 113 is made of PP or polypropylene, has outstanding ductility and fatigue resistance, and serves as a buffer.

[0046] There are more than two ball milling blocks 112, with three ball milling blocks 112 forming a group. The distances between two adjacent groups of ball milling blocks 112 are equal, and the ball milling blocks 112 are horizontally linearly arranged at the top of the notch 117 of the blocking bar 116. When the integrated circuit board 12 is skewed due to a collision, the blocking bar 116 can not only serve as a horizontal buffer, but also can be fixed by friction from top and bottom through the ball milling blocks 112.

[0047] refer to Figure 2 , Figure 3The anti-collision structure 11 also includes a buffer spring 114. A circular placement opening 115 is opened at the end of the soft panel 113. There are two buffer springs 114, which are respectively installed in the placement openings 115 at the front and rear ends of the soft panel 113. The buffer spring 114 not only serves as a cartilage support for the soft panel 113, but also serves as a guide for its rebound and expansion. After the collision, it serves as a reverse force to give the soft panel 113 the power to reset.

[0048] refer to Figure 2 , Figure 3 The surface of the ball mill block 112 is provided with more than two groups of curved bending circles, and each group of bending circles is formed by the straight roots of two adjacent curved bending bars being crossed and fixed, and the curved bending bars are made of tanned polyester fibers, which will not cause wear when the ball mill block 112 contacts the ball mill block 112.

[0049] refer to Figure 2 , Figure 3 The number of the blocking bars 116 is an odd number, and they are arranged in parallel on the bottom surface of the soft panel 113 at the bottom of the recess 117 , thereby improving the blocking friction effect of the blocking bars 116 .

[0050] refer to Figure 2 , Figure 3 The number of the blocking bars 116 is an even number, with two blocking bars forming a group, and two blocking bars 116 in each group are arranged crosswise to improve the blocking friction effect of the blocking bars 116.

[0051] Please refer to Figure 1 , Figure 4 , the structure of the filter 13 includes:

[0052] Resistor 131, more than two resistors 131 are provided, the number is an even number, these resistors 131 are evenly divided into two groups, the two groups are connected in parallel and are electrically connected to the integrated circuit board 12 and the ground pin 136 respectively, the outer side of the resistor 131 is wrapped with an insulating shell 133, the insulating shell 133, the other end surface of the insulating shell 133 opposite to the integrated circuit board 12 is provided with more than two wedge-shaped blocks 134, the wedge-shaped block 134 is fixed to the shell 5 through a fixing ring a; the multiple resistors of the present invention are connected in series into a group and then connected in parallel, and the signal converted by the radio frequency interface module 2 will be clearer after being filtered by these resistors, so that the electronic tag read and written by the integrated circuit board 12 is clearer.

[0053] Please refer to Figure 1 , Figure 4 , Figure 5The cross-sectional shape of the fixing ring a is concave, and an arc-shaped piece b is provided on the bottom surface of the notch of the fixing ring a. The length of the arc-shaped piece b is greater than the horizontal width of the notch of the fixing ring a. The horizontal ends of the arc-shaped piece b are embedded in the side surfaces of the fixing ring a. The arc-shaped top surface of the arc-shaped piece b and the wedge-shaped block 134 are movably fitted. The bottom surface of the fixing ring a is glued to the bottom end surface of the shell 5. By utilizing the structural characteristics of the arc-shaped piece b and the fixing ring a, once the wedge-shaped block 134 is embedded in the notch of the fixing ring a, the horizontal fixation of the end surface of the fixing ring a and the upward push of the bottom arc-shaped piece b are clamped together, and it is not easy to fall off, thereby enhancing the connection relationship between the filter 13 and the shell 5.

[0054] Please refer to Figure 1 The RF interface module 2 is provided with triangular support plates 15 on both horizontal sides. The support plates 15 are right-angled triangles, and are fitted with the RF interface module 2 along their vertical right-angled sides. By utilizing the stable characteristics of the triangle, when the RF interface module 2 falls heavily, its stability is enhanced, and it is not easy to be skewed. The RF interface module 2 is always kept on a central axis, so that the connection port is not easy to loosen.

[0055] The use steps and technical effects of the present invention in an intelligent logistics distribution system based on the Internet of Things are as follows:

[0056] First, hold the handle 4 and align the exposed portion of the radio frequency interface module 2 on the surface of the housing 5 with the electronic tag for reading and writing;

[0057] Second, compared with the handheld RFID reader / writer on the market, the signal read and written by the radio frequency interface module 2 of the present invention will be connected in series through multiple resistors into a group and then connected in parallel. The signal converted by the radio frequency interface module 2 will be clearer after being filtered by these resistors, making the electronic tag read and written by the integrated circuit board 12 clearer, thereby improving the anti-interference ability;

[0058] Third, if a serious collision occurs when holding the handheld RFID reader, such as falling to the ground or hitting the wall, firstly, because the front and rear ends of the integrated circuit board 12 are fixed on the housing 5, if this position is offset, whether it is to the left or to the right, the integrated circuit board 12 will gradually tilt into the soft panel 113. In this process, the wavy top surface of the blocking bar 116 will increase its movement difficulty, increase the buffering force, and prevent the integrated circuit board 12 from directly hitting the inner surface of the housing 5, causing damage. At the same time, the interface with the filter 13 is also unstable, resulting in information deviation. The ball mill block 112 is also used to rub and fix from top to bottom to enhance the buffering effect;

[0059] Fourth, after the collision, the buffer springs 114 on both sides of the soft panel 113 not only serve as cartilage supports for the soft panel 113, but also serve as guides for its rebound and expansion. After the collision, they serve as a reverse force to give the soft panel 113 the power to reset.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
