Abstract: This present invention relates to a method for processing response messages, comprising a transmitter, first communication gateway, second communication gateway and a receiver, wherein the transmitter is connected with the first communication gateway, while the receiver is linked with the second communication gateway. When a message is transmitted by the transmitter via a mobile communication network to a remote receiver, the second communication gateway will transmit a response message to the transmitter after the transmitter receives the message. The first communication gateway will determine that the receiver does not receive the message successfully if it does not receive the response message within a given time period, and then transmit the message again or inform the administrator. In this way, it can help reduce the loss of property and life to enterprises and their employees caused by loss of messages.

Abstract: A method of detecting response time-out based on master-slave protocol architecture, which calculates the time required for a slave device to respond to a Modbus request sent by a detection device based on Modbus communication protocol. The method is to send a Modbus request to the slave device through a detection device, and to record the Modbus request sent time, and then to have the slave device provide to the detection device a response. The detection device calculates the response time-out based on the request sent time and the response received time By means of calculating the precise response time-out from the response time-outs which are gotten from the slave device respond to a predetermined number of Modbus requests, the user or manager can determine the response time-out required for the slave device precisely so as to give EXECUTE instruction or command at the accurate time point.

Abstract: The present invention relates to an auto-restore method for a power device by using a computer device to build a detecting/responding packet in an Ethernet exchanger, and the Ethernet exchange can mutually transmit the packet with the power device. If the Ethernet exchanger fails to receive a responding packet from the power device in the predetermined time and the predetermined value, the Ethernet exchanger will terminate power supply by the Ethernet and reset the power device, and the power device will be restored automatically accordingly. If the power device still cannot function normally after few times of reset, the Ethernet exchanger will shutdown the power supplied by the Ethernet and transmits an alarm signal to the computer device. Thus not only the consumption of the system and safety risk are reduced, but also promptly maintained, to increase the reliability, and save the supervision time of the operator and the cost of onsite maintenance.

Abstract: This specification discloses a transmission system, device and method that prevent data loss. The invention uses a first channel and a second channel to send same packet encapsulating same target data to a receiving end. After confirming the reception of the packet, the receiving end drops the duplicated packet. The receiving end only processes yet processed packet. This technique can reduce the chances of losing data.

Abstract: This specification provides a backup system that stores a boot data file of an embedded system in a different storage section and a method thereof By generating several file systems and after defining one of them as the backup file system, the backup boot data file is stored in the backup file system. When normally used boot data file cannot be used for booting, the backup boot data file is used. This solves the problem that the backup boot data file is stored in a file system that the user can freely access and thus may be damaged by the user. This achieves the technical feature that a specific embedded system can have several different file systems to store multiple boot data files.

Abstract: A heat-dissipating structure for the expansion board architecture is provided. A fixing element disposed on the heat-absorbing substrate fixes the motherboard and the first expansion board. The heat-generating elements on the motherboard or the first expansion board are directly in touch with the heat-absorbing surface of the heat-absorbing substrate to absorb their heat. The heat-dissipating board extended from the side of the heat-absorbing substrate then dissipates the heat absorbed by the heat-absorbing substrate. The structure thus solves the problems that existing heat-dissipating structures occupy larger space and therefore cannot be effectively used in an expansion board architecture to dissipate heat produced by the heat-generating elements between the motherboard and the expansion board and that it is likely to have assembly tolerance. Using the structure can reduce the space and the assembly tolerance, but effectively enhance heat dissipation in the expansion board architecture.

Abstract: The present invention relates to a method for disconnecting a transceiver from a bus in multipoint/multidrop architecture. A central processing unit (CPU) and a universal asynchronous receiver transmitter (UART) in a system are connected to a controller used for storing and transmitting data, and the controller is further connected with a bus through a transceiver that monitors/records data and a relay that connects or disconnects the transceiver from the bus. The controller comprises a signal comparator used to compare similarities and differences of data and a failure detection controller used to achieve connection or disconnection of the bus with the transceiver. In case of the transceiver's failure, the controller disconnects the transceiver from the bus to ensure that the bus does not fail to work due to breakdown of the transceiver.
