DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0023] Combination Figure 1-Figure 7 The utility model of the wireless intelligent anti-collision equipment for automated warehousing and transportation includes a transmitting device 1 and a receiving device 5. The transmitting device 1 includes a transmitting base 2, and a trigger device 4 is installed inside the transmitting base 2. The trigger device 4 is connected to the transmitter 3 installed inside the transmitting base 2. The receiving device 5 includes a receiving base 6, and a receiver 7 is installed inside the receiving base 6. The transmitting device 1 is respectively installed on the four corners of the rectangular fork arm of the transportation equipment, and the receiving device 5 is installed near the control unit of the transportation equipment and connected to the PLC. The receiver 7 is wirelessly connected to the transmitter 3.

[0024] Specifically, when in use, the transmitting bases 2 of the four transmitting devices 1 are respectively installed on the four corners of the rectangular fork arms of the transportation equipment, and the receiving base 6 of the receiving device 5 is installed near the control unit of the transportation equipment and connected to the PLC. When any trigger device 4 of the four transmitting devices 1 is triggered, the transmitter 3 will be controlled to send a coded signal, and after the receiver 7 on the receiving device 5 receives the signal, it will output a signal indicator light signal and an alarm signal. After receiving the alarm signal, the PLC controls the motor to execute a stop command, thereby preventing a collision from occurring. The wireless collision avoidance system can avoid losses caused by collisions, provide safety protection for on-site equipment, and reduce the difficulty of monitoring safety equipment. The linkage detection of the four transmitting devices 1 can achieve all-round coverage of the surrounding environment of the transportation equipment, thereby ensuring high-precision collision detection.

[0025] The utility model is further described below in conjunction with embodiments.

[0026] Embodiment 1:

[0027] Combination Figure 4-Figure 5 Two symmetrical card plates 202 and a fixed plate 203 are fixed inside the launch device 1. The trigger device 4 includes a guide sleeve 402 fixed between the fixed plate 203 and the side wall of the launch base 2. A pressure rod 401 is slidably connected inside the guide sleeve 402. One end of the pressure rod 401 is connected to a slider 403. The slider 403 slides between the two card plates 202. One end of the slider 403 contacts a pressure block 404. The eccentric protrusions on both sides of the pressure block 404 are rotatably connected to the card plate 202. There is a self-generating module 405 directly above the pressure block 404, which is fixed at the bottom of the launcher 3. The top surface of the pressure block 404 contacts a rotating button 4051 installed at the bottom of the self-generating module 405. When a collision occurs, the pressure rod 401 will be touched first, and the pressure rod 401 will slide inside the guide sleeve 402. The guide sleeve 402 is fixed between the fixed plate 203 and the transmitting base 2 and does not move. The pressure rod 401 and the slider 403 are tightly connected, so the slider 403 will also move forward. With the movement of the slider 403, the eccentric protrusions on both sides of the pressure block 404 will rotate on the card plate 202, moving the pressure block 404 upward to generate thrust, so that the rotating button 4051 is pressed once, triggering the self-generating module 405 to work. When triggered, a DC voltage of 2.2V is generated for 17 milliseconds to power the receiver 7, and the receiver 7 will send the encoded signal through the antenna.

[0028] A spring 406 is connected between the pressure rod 401 and the inner cavity of the guide sleeve 402, and the spring 406 is compressed when the pressure rod 401 touches and slides into the inside of the launching base 2. The spring 406 is connected between the pressure rod 401 and the inner cavity of the guide sleeve 402, so that after the device stops moving and is moved to a safe state, the pressure rod 401 is automatically reset. There is no need to manually adjust the reset of the pressure rod 401, thereby improving applicability and efficiency of use. Automatic reset can also prevent continuous pressing of power supply and save energy.

[0029] Embodiment 2:

[0030] Combination Figure 2-Figure 3 and Figure 6-Figure 7 A transmitting upper cover 201 is arranged on the top of the transmitting base 2, and a receiving upper cover 601 is arranged on the top of the receiving base 6. Arranging the transmitting upper cover 201 on the top of the transmitting base 2 and the receiving upper cover 601 on the top of the receiving base 6 can effectively prevent dust from entering the interior of the device and effectively improve the service life of the device.

[0031] The four corners of the transmitting base 2 and the receiving base 6 are set to be concave and are provided with bolt holes. The four corners of the transmitting base 2 and the receiving base 6 are set to be concave and bolt holes are provided in the concave parts, which facilitates the installation of the device without protruding bolts. The bolts are installed within the range of the device to increase the safety of the device.

[0032] The transmitting frequency of transmitter 3 is 433.2MHZ, and the receiving frequency of receiver 7 is 433.2MHZ. Setting transmitter 3 and receiver 7 to the specified frequency of 433.2MHZ can reduce frequency conflicts with other wireless communication devices, which helps to ensure the stability and reliability of wireless communication. This frequency has lower attenuation and better penetration ability as well as lower noise and interference, which helps to improve the quality and reliability of wireless communication.
