5results about How to "Simplify communication" patented technology

The invention relates to a communication isolation device and a safety communication method of the isolation device, and belongs to the technical field of safety communication. According to the method, a communication port range is added in a secure communication strategy configuration file of a communication isolation device, the port range compatibly represents an existing single port mode, and the communication isolation device judges whether to communicate with a port requesting communication or not according to an ip address, an mac address and the communication port range in the secure communication strategy configuration file. And if the port requesting communication is within the normal communication port range configured in the security communication strategy configuration file, allowing communication, otherwise, blocking the communication request. The method and the device are used for solving the problems that in the prior art, when communication is carried out with different port services on the same physical link, a secure communication strategy configuration file needs to be modified again, so that the configuration process is troublesome, and use is inconvenient.

The invention relates to the technical field of communication, and discloses a method for industrial wireless communication and data transmission, which is applied to a gateway of an industrial detection system, and the industrial detection system comprises: a PLC device configured to collect detection data of a target device; the gateway is configured to communicate with the PLC equipment and receive detection data sent by the PLC equipment; the router is configured to wirelessly communicate with the gateway and receive the detection data sent by the gateway; the server is configured to communicate with the router and draw a detection curve for detection analysis according to the detection data sent by the router; the method comprises the following steps: storing detection data sent by PLC equipment in a message queue of a gateway; determining target data in the message queue according to the message ID in the request instruction under the condition that the request instruction for requesting the detection data sent by the router is received for the nth time, n being equal to 1, 2,...; and sending the target data and the received message ID to the router, and storing the received message ID. According to the method, the communication process is simpler, and the communication efficiency is improved.

The invention relates to a sitting posture and fatigue monitoring device and method.The device comprises a seat, a support, a mobile phone and a server, the seat is provided with a backrest, a cushion and a control circuit, the backrest and the cushion are provided with a plurality of pressure sensors, the control circuit is arranged at the bottom of the seat, one end of the control circuit is connected with the pressure sensors, and the other end of the control circuit is connected with the mobile phone through Bluetooth; the mobile phone is supported in front of the seat through the support, a camera of the mobile phone faces the seat, the mobile phone is connected with the server through application software, the pressure sensor collects pressure data, the mobile phone shoots video data, and the server obtains a sitting posture evaluation result and a fatigue monitoring result through the pressure data and the video data. Compared with the prior art, the method has the advantages of high accuracy, high robustness and the like.

A system for sensing the position of a work machine or loading truck includes an actuator arm suspended downwards from a secondary conveyor of a milling assembly. The actuator arm responds to contact with the truck's tailgate or rear via motion and angle measurements detected using a linear transducer, inclinometer, rotary position sensor, or proximity switch. Based on a predetermined angle measurement, the system triggers an indicator light visible to the truck driver to indicate when to stop or move forward to achieve uniform load distribution. The system can be integrated with software for enhanced control options and requires only a power supply and grounding connection for mounting on the work machine.
