METHOD AND DEVICE FOR ADAPTING CAPACITY OF STORAGE DEVICE IN EMBEDDED SYSTEM

Номер: WO2012159478A1
Автор: WANG, Xuguang, XU, Yun, LIU, Jindong, WU, Qi
Принадлежит:

Disclosed are a method and device for adapting the capacity of a storage device in an embedded system, which are applied to a Linux system. The method comprises: mapping a virtual memory, and performing a primary detection on the storage device to obtain the actual capacity of the storage device; re-mapping the virtual memory according to the actual capacity of the storage device, and performing a secondary detection on the storage device; and adding a corresponding partition table and registering the table. Through the present invention, the drive of different Flash capacities can be realized in the Linux kernel, and in spite of the size of the Flash capacity, the Flash drive loading and the loading of the corresponding partition table can be automatically implemented, thereby reducing the maintenance cost of the product and improving the flexibility and reliability of the product.

Номер: WO2012126219A1
Автор: LIU, Jindong, XU, Yun, WU, Qi, WANG, Xuguang
Принадлежит:

A roadside identifier station and a method for a primary /a standby roadside unit (RSU) switching are provided by the present invention. The roadside identifier station includes a management central device, an optical transceiver, a primary inverter, a standby inverter, a primary RSU and a standby RSU. The management central device includes: a query module, configured to query the states of the primary RSU and the standby RSU; a switching module, configured to determine, according to the query result of the query module, whether the switching condition is satisfied and to carry out the primary/standby RSU switching if the condition is satisfied. The primary RSU includes a primary state-interactive module and a primary state-report module and the standby RSU includes a standby state-interactive module and a standby state-report module. Based on the method and device of the present invention, the problem that the roadside identifier station can not keep a normal state persistently is solved ...

RADIO FREQUENCY IDENTIFICATION SYSTEM BASED COMMUNICATION METHOD, APPARATUS AND SYSTEM

Номер: WO2012136019A1
Автор: WU, Qi, XU, Yun, LIU, Jindong, WANG, Xuguang
Принадлежит:

A radio frequency identification system based communication method, apparatus and system are disclosed, which are used for implementing bi-directional communication between an electronic tag and a reader in the radio frequency identification system, saving battery power consumption in an active electronic tag, and guaranteeing communication stability between the electronic tag and the reader. Wherein, the method includes: receiving data frames sent by the reader in the current checking period, analyzing the data frames and extracting frame sequence numbers from preset fields, calculating waiting time required for the current checking period to enter into a channel idle state based on the extracted frame sequence numbers, selecting one timeslot from timeslots included in the current checking period when determining the reader is in the channel idle state, and transmitting messages to the reader based on the selected timeslot.
