[0002] With the progress of technology and the development of society, mobile robots (such as AGV, AMR, etc.) are increasingly widely used in buildings, hospitals, warehouses and other places. These places often have multi-storey building structures, and mobile robots need to be able to efficiently and safely cross floors, which involves the use of elevators. The demand for intelligent buildings increases with the popularity of the concept of intelligent buildings, and more and more buildings begin to use automated equipment and service robots to improve operational efficiency and service quality. In this case, as the key equipment connecting different floors, the efficiency of the elevator directly affects the automation level of the entire building. Logistics and warehouse automation In the logistics and warehousing industry, automated handling robots (AGV) and autonomous mobile robots (AMR) are increasingly widely used. In order to achieve cross-floor material handling, these robots need to be able to use elevators independently, thereby improving handling efficiency and accuracy. Development of medical service robots Medical service robots are also increasingly common in hospitals, and they can help transport medicines, samples, medical records and other items. In multi-storey hospital buildings, these robots need to be able to use elevators independently to complete tasks, ensuring the timeliness and safety of medical services. Service robots in commercial and office environments In commercial and office environments, service robots can be used for tasks such as receiving visitors, providing information consultation, and transporting documents. In order to be able to provide services between different floors, these robots also need to have the ability to use elevators. For safety and efficiency considerations, traditional elevator control systems are usually designed for people and lack support for mobile robots. Therefore, it is necessary to develop a special mobile robot elevator control system so that the special needs of the robot can be better met, such as faster response speed, higher safety standards, etc. SUMMARY

[0011] The mobile robot elevator control system will be further described below in combination with the drawings and embodiments:

[0012] A mobile robot elevator control system includes a wireless radio frequency module, an industrial computer, an Ethernet-port RFID card reader, RFID electronic tags, and a relay output module with a 485 communication switch output. The wireless radio frequency module, model E90-DTU, is installed in the mobile robot and the elevator car. The wireless radio frequency module in the elevator car communicates with the wireless radio frequency module on the mobile robot through a wireless serial port to implement robot-to-elevator call control. The industrial computer and the Ethernet-port RFID card reader are installed on the top of the elevator car. RFID electronic tags are distributed on each floor. The Ethernet-port RFID card reader reads the RFID electronic tag information on each floor. The Ethernet-port RFID card reader interacts with the industrial computer. The industrial computer processes the data and controls the elevator floor button triggering or door opening signal triggering through the relay output module with a 485 communication switch output.

[0013] The wireless radio frequency module converts the serial data into 433 data for remote transmission, and the wireless serial port transmits the information to the robot.

[0014] During operation, the E90-DTU wireless radio frequency module installed on the elevator car roof communicates wirelessly with the E90-DTU installed inside the robot. The industrial computer on the elevator car roof works in conjunction with an Ethernet-based RFID reader for floor information collection to read the RFID tags on each floor, determine the elevator's location, and then transmit this information to the mobile robot via a wireless serial port. The robot then feeds back elevator control information to the industrial computer, which then controls the elevator's floor button triggering or door opening signal triggering via a relay output module and a 485 communication switch output module. This wireless connection between the mobile robot and the elevator system provides users with a more convenient and intelligent service experience, especially in large buildings, hospitals, warehouses, and other places, greatly improving the efficiency of transporting personnel and materials.
