A data collecting apparatus sets types of target ECUs, and stores, in a storage unit, driving parameter data items, which are capable of being output by a plurality of ECUs, in association with IDs of the plurality of ECUs. Subsequently, for each of the aforementioned types, a query is made to a vehicle as to whether an installed ECU exists, and the installed ECU is identified as a target ECU. Thereafter, based on the ID of the installed ECU, driving parameter data items capable of being output by the installed ECU that was identified as the target ECU are set as collection items.

The invention discloses a data communication module of a motor protector. The data communication module comprises a central processing unit, a storage unit, a power supply unit, a configurable module, a local application interface, field control interfaces and a connector assembly, wherein the field control interfaces comprise a status input interface, a status output interface, a data acquisition module and a data uploading interface; the connector assembly is used for signal connection; the data acquisition interface of the field control interfaces is arranged on the communication module for acquiring current, voltage, startup time, operation and fault data of a motor; the data uploading interface is arranged on the communication module for packing the acquired data according to the requirements set by the user and then uploading the packed data to an upper communication device for an upper acquisition system. The data communication module of the motor protector disclosed by the invention is used for judging whether data acquisition is carried out to the motor protector or not by monitoring the operation status of an MCC (Motor Control Center) switch cabinet motor protector, so that system does not waste redundant communication time.

The present invention discloses a method and system for collecting data of amount of travelling vehicles, and the method includes: establishing a usage amount model based on car networking original data sent by three types of information bodies of "human, vehicle, and road," wherein the usage amount module includes travelling vehicle usage amount association rules corresponding to different items of the different information bodies; and performing associated collection on the car networking original data sent by the three types of information bodies of "human, vehicle, and road" based on the established usage amount module. Therefore, the method and system provided in the present invention collectively collect and analyze the data resources in the car networking and optimally use the analyzed data resources.

The present invention provides an anti-collision method and system for multi-channel digital quantity collection and processing of multiple sets of inertial navigation systems. The write-read switch of the first-level cache, when the first-level cache is unavailable, the collected data is stored in the second-level cache, and the data read from the first-level cache is framed, and the assembled The data frame is written to the third-level cache. The present invention overcomes the problem of data collection and processing task conflicts through the dynamic creation of multi-level caches, and at the same time creates multiple sets of caches that are independent of each other, and the caches of different groups adopt a parallel working mode to improve data processing speed and avoid multiple sets of inertial navigation systems. When the digital quantity is output, there is a conflict between data acquisition and processing tasks, which greatly improves the testing and production efficiency of the inertial navigation system.

The invention discloses an over-coverage cell determining method and device, relates to the field of communication technology, and can save a lot of human and material resources. The method comprises that a first distance, a first amount and the switching success frequency between a target cell and each adjacent cell are obtained; the dynamic coverage radius of the target cell is obtained according to the first distance, the first amount and the success frequency; a second distance and a second amount are obtained; an over-coverage proportion of the target cell is obtained according to the second distance, the dynamic coverage radius and the second amount; and when the over-coverage proportion is greater than or equivalent to a preset proportion, the target cell is determined to be an over-coverage cell. The method and system can be used to determine whether over coverage occurs in the cell.

The invention relates to the technical field of infrared positioning, and more particularly to a method and system for determining the sampling time of infrared data. The method comprises the following steps: calculating the rising slope of the signal received by the infrared receiving tube; calculating the virtual peak value of the signal received by the infrared receiving tube according to the rising slope and the actual peak moment of the signal received by the infrared receiving tube; combining the virtual peak value of the signal received by the infrared receiving tube with the Comparing the saturation value of the signal received by the preset infrared receiving tube to determine the data sampling time of the infrared receiving tube. The present invention can effectively prevent the infrared receiving tube from collecting data at the time of oversaturation of the received signal, thus effectively avoiding the situation that the received signal collected when the light emitted by the infrared receiving tube is still saturated, and at the same time ensures that it does not enter into oversaturation The receiving sensitivity of the infrared receiving tube in the state can improve the positioning accuracy and sensitivity of the infrared positioning device.
