Operational administration system enabling reduction in expense burden on user, and permitting manufacturer to comprehend accurately and timely operational status of machine tools on user end. Operational administration system (1) includes, interconnected via Internet (5): manufacturer-end administration device (20); operational data storage/transmission devices (10) connected to numerical controllers for NC machine tools (15); and user-end terminal device (30). The operational data storage/transmission devices (10) gather from the numerical controllers data pertaining to the operational status of the NC machine tools (15), store the data and, when specified transmission conditions are met, send the stored operational status data to administration device (20) in an e-mail data format. With the received operational status data, administration device (20) updates operational status data it stores, and sends to terminal device (30), in response to a request therefrom, machine-tool operational status data identified by user ID information appropriately input through terminal device (30).
摘要:
An operation management system 1 according to the present invention is configured so as to connect an operation data accumulation and transmission device 10 connected to an NC unit 16 to an operation management device via telecommunication circuits 20. The operation data collection and transmission device 10 collects data on an operating condition of a machine tool 15 to store the same in an operation data storage section 12, and based on the accumulated operating condition data, generates transmit data with a configuration for associating a data-element identifier which defines an item concerning operating condition with operating condition data corresponding to this item to transmit the same to the operation management device. The operation management device analyzes the data-element identifier of the received data, recognizes the operating condition item and updates the operating condition data in databases corresponding to the recognized item by the received operating condition data.

摘要:
The invention relates to a maintenance system for machine tool. In the maintenance, system 1, a user management apparatus 10 connected to a numerical control section of a machine tool 15, and a manufacturer management apparatus 20 disposed on a side of a manufacturer are connected to each other via Internet 5. The user management apparatus 10 collects data relating to an operating condition of each driving mechanism of the machine tool 15, and accumulates the data. When a predetermined transmission condition is satisfied, the user management apparatus 10 transmits the accumulated operating condition data to the manufacturer management apparatus 20 in the form of an electronic mail. The manufacturer management apparatus 20 evaluates the consumption degree of each driving mechanism based on the received operating condition data, and outputs an alarm when the consumption degree exceeds a reference value.

[Problem]Problem is to discard erroneous data more surely, and to receive correct data more surely.[Means to solve the problem]A receiving apparatus to receive data by use of a second protocol data unit, which stores a plurality of first protocol data units of a first layer set for each of plural radio bearers and which is based on a second layer corresponding to a lower layer of the first layer, includes a providing means for providing the first protocol data unit, which is stored in the second protocol data unit with specific information specifying the second protocol data unit in the second layer and a discarding means for discarding. another first protocol data unit, which is stored in the second protocol data unit storing the erroneous first protocol data unit with reference to the specific information in the case that a predetermined first protocol data unit includes an error in the first layer.
摘要:
This invention is to prevent deterioration in communication quality of closed loop transmission power control, which may occur when the change in transmission power cannot keep up with a sudden change in the state of a transmission path. Transmission power control command extractor 4 extracts a transmission power control command from the uplink signal that has been received by receiver 2. Mobile position predictor 7 predicts the future position of the mobile station from its present position as recognized by mobile position recognizer 5 and from its present rate of movement as recognized by mobile velocity recognizer 6. Database 8 records the state of the downlink transmission path as a function of mobile position. Transmission power controller 9 looks up database 8 on the basis of the predicted future position of the mobile station and controls the downlink transmission power of base station BS on the basis of (i) the result of this lookup, and (ii) the transmission power control command. Transmitter 11 transmits at the downlink transmission power that has been instructed by transmission power controller 9.
摘要:
An SIR measurement sections are provided for respective stages of an interference canceller section and SIR values of the respective stages of the interference canceller section is notified to a station of the other end of a communication link to allow the station to determine the number of operation stages of the interference canceller section. The determined number of operation stages is received from the station and the interference canceller section is operated by the determined number of operation stages. This reduces processing time and power consumption. Further, the reduction in processing time makes it possible to perform communication according to an adaptive transmission method in an error-free manner.
