An operator cab 53 , which is mounted rotatable on the vehicle body 51 of a hydraulic mini-shovel 50 , comprises a cab box 1 , a door 2 , upper and lower link members 3 and 4 , a slide member 6 , a closed door lock 7 , an opened door lock 9 and a handle 13 . The cab box 1 has an internal cab room 1 a and an entrance 15 , which leads into the cab room 1 a. The door 2 closes and opens the entrance 15 when it is moved forward and rearward, respectively. The upper and lower link members 3 and 4 have fixed ends 3 a and 4 a, each of which is connected pivotally to the cab box 1 , and moving ends 3 b and 4 b, each of which is connected pivotally to the front end of the door 2 . The slide member 6 is connected pivotally to the rear end of the door 2 so as to swing freely and slides along a slide rail 5 , which is provided externally on the cab box 1 . The closed door lock 7 , which is provided at the front end of the door 2 , engages with a closed door striker 8 , which is provided on the cab box 1 , when the door 2 is closed. The opened door lock 9 , which is provided at the front end of the door 2 , engages with an opened door striker 10 , which is provided on the cab box 1 , when the door 2 is opened. The handle 13 is provided at the front end of the door 2 and interlocked with the closed door lock 7 and the opened door lock 9.

The invention provides a method for vehicle safety remote control and diagnosis and a system thereof. A control and diagnosis terminal and a cloud side instruction server perform first identity authentication and key agreement; a vehicle-mounted terminal and the cloud side instruction server perform second identity authentication and key agreement; and the control and diagnosis terminal establishes communication connection with the vehicle-mounted terminal through the cloud side instruction server and performs remote control or remote diagnosis on a vehicle according to the control and diagnosis instruction of a user. Different secret keys are adopted between the control and diagnosis terminal and the cloud side instruction server and between the vehicle-mounted terminal and the cloud side instruction server and so that the information security of remote control and diagnosis information can be guaranteed, and the problem of security insufficiency in the prior art can be effectively solved. The system for vehicle safety remote control and diagnosis has the advantages of being scientific in design, high in practicality, convenient and rapid, high in security and high in reliability.

The invention provides a security remote control system and method for industrial equipment. The system comprises industrial equipment, a control terminal and a cloud platform, wherein a security module I is arranged in the industrial equipment, a security module II is inserted into or arranged in the control terminal, the cloud platform comprises a security access gateway, a management system, aCA certificate management system and a forwarding server, and a security module III is arranged in the security access gateway. In remote control, the industrial equipment and the security access gateway perform bidirectional identity authentication and key negotiation and create a first session key; the control terminal and the security access gateway perform bidirectional identity authenticationand key negotiation and create a second session key; the control terminal and the industrial equipment perform bidirectional identity authentication and key negotiation through the forwarding serverand then create a third session key; and the control terminal performs security remote control on the industrial equipment by using the third session key through the forwarding server.

The present invention relates to a 5G-based industrial control security communication system and method, including a cloud and at least two control terminals; the cloud includes a certificate server, a cloud security module and an industrial control server; the control terminal includes a 5G communication module, a control terminal security module and Industrial control module; the industrial control server communicates with the 5G communication module through the 5G network, and the control terminal is connected by the field bus. The cloud security module and the control terminal security module provide password and storage services. The password service includes random number generation, signature verification calculation, Encryption and decryption operations, session key generation and hash operations; the industrial control server calls the cloud security module password service, and the industrial control module calls the control terminal security module password and storage services; the certificate server generates public key certificates for the cloud and the control terminal, and the public key The certificate public key is written into the security module of the control terminal; the cloud security module and the security module of the control terminal store the corresponding private key to realize identity authentication and group secure encrypted communication between control modules.

The present invention relates to a 5G-based V2X Internet of Vehicles security communication system and method, including a cloud, a vehicle terminal, a roadside terminal, and a pedestrian terminal, and the sum of the vehicle terminal, roadside terminal, and pedestrian terminal is at least two; the cloud includes a certificate Server, cloud security module and Internet of Vehicles server; the vehicle end includes the short-distance direct communication module of the vehicle end, the 5G communication module of the vehicle end, the security module of the vehicle end and the control module of the vehicle end; the roadside end includes the short-distance direct communication module of the roadside end, Roadside terminal 5G communication module, roadside terminal security module and roadside terminal control module; pedestrian terminal includes pedestrian terminal short-distance direct communication module, pedestrian terminal 5G communication module, pedestrian terminal security module and pedestrian terminal control module; according to 5G and V2X The characteristics of the Internet of Vehicles realize the V2X Internet of Vehicles identity authentication and group secure encrypted communication, making the V2X Internet of Vehicles identity authentication and group secure encrypted communication safe, reliable, simple and efficient.
