The invention relates to a Bluetooth communication technology, and particularly relates to a device communication method and system for a wireless communication system. The method comprises the stepsthat S100 slave equipment establishes a monitoring link for communication between master equipment and host equipment; S200 the slave equipment negotiates with the master equipment to enter a monitoring confirmation mode; the monitoring link enters a monitoring confirmation mode; the master equipment and the host equipment enter the monitoring confirmation mode; and S300 the communication link between the slave equipment and the master equipment exits the monitoring confirmation mode after information interaction is completed. The system comprises the master equipment carrying a Bluetooth communication protocol, the slave equipment and the host equipment. According to the invention, the power consumption of the master equipment and the slave equipment can be reduced by reducing one link, which is helpful for reducing the burden overhead of the equipment and improving the user experience.

The invention relates to a vehicle-mounted network system and a communication method thereof. The vehicle-mounted network system comprises a signal system device, a TCMS device, other vehicle-mountednetwork subsystem devices and two mutually independent subnetworks. The signal system equipment is directly connected to the first sub-network A and the second sub-network B respectively. The TCMS device and other vehicle-mounted network subsystem devices are classified into key subsystem equipments with high security level and common subsystem equipments with low security level according to security level, The key subsystem equipment is connected to the first subnetwork A and the second subnetwork B through two or more communication interfaces, and the common subsystem equipment is directly connected to the first subnetwork A or / and the second subnetwork B. The invention integrates the signal system network and the TCMS network into the same network, reduces the complexity of the vehicle-mounted network system and reduces the fault point of the system. The two sub-networks are hot-standby each other, which can ensure that the normal operation of on-board network equipment is not be affected when any one of them has an irrecoverable failure.

The invention discloses an intelligent gate level meter with a dual-bus communication redundancy and remote control function. The intelligent gate level meter comprises a data acquisition, data operation and communication module and an input-output control and data display module which are arranged in one shell. The intelligent gate level meter has a reasonable structure, and integrates multiple functions of gate openness detection, data processing, opening-closing control, communication and the like. A layered distributed gate automatic remote control system can be conveniently formed, therefore, gate descending and ascending control and various protection measure programs are embedded inside the intelligent gate level meter, control units such as a PLC can not be used, programming is not used, and a gate automatic remote control function can be realized. The gate automatic central control system has the advantages of simple structure, convenience for maintenance and lower investment.

The present invention relates to a display performance testing method, a system and a display performance testing device. The method comprises a step of receiving the testing instruction of testing display equipment display performance, wherein the testing instruction comprises the signal channel of the display equipment, a signal source and a testing process, a step of selecting the signal channel of the display equipment according to the testing instruction and controlling the display equipment to obtain a test image from a corresponding signal source through the signal channel, a step of shooting the displayed test image to obtain a first shooting image, and a step of carrying out display performance testing on the corresponding display equipment according to the testing process and the first shooting image and outputting the testing result of the display performance testing. According to the display performance testing method, the system and the display performance testing device, the automation of the display performance testing process can be realized, and the testing efficiency of the display equipment is improved.

The invention discloses a method for recovering networks in a ring network. Ethernet switch equipment enters a communication status after an initial configuration and precise time synchronization based on an IEEE 1588 protocol. Each equipment according to the configuration of the network sends out time-sharing equipment statement messages and link circuit checking messages. The link circuit checking messages are sent by a multicast address in two ways; if a port of equipment receives no link checking messages of a connected port after the time out, then a network trouble can be determined andlink circuit alarm messages are sent by the multicast address in two ways for alarming. The rest equipments in the ring network after receiving the link circuit alarm message, then empty an FDB list and utilize a backup link circuit to restart path learning. By adopting the method of the invention, any communication link circuit failure in the ring network can be quickly detected and correspondingly processed, thereby meeting the availability requirements of Ethernet communication by the industrial automatic field.

The invention discloses a method for interactively sharing an SPI communication bus through embedded system multiple processes. The method comprises the following steps: (1) a system is initialized and the processes are built; (2) all kinds of SPI information are marked one by one by the system; (3) the processes respectively register required SPI information for the system; and (4) SPI information is respectively sent to each corresponding process by the system according to marks of the received SPI information. The method for interactively sharing the SPI communication bus through the embedded system multiple processes has the advantages that each process of an application layer is respectivley provided with an independent SPI communication queue, can respectivley register SPI information focused by the process according to requirements, and does not need to process interaction of other SPI information. Single-process SPI communication is not limited by other processes any more, whether the SPI information needs processing or not is completely not affected by other processes, and building of a process and exiting of the process are not affected by other processes. If an SPI information queue of a process is blocked, communication of other processes is completely not affected, and therefore system stability is improved.
