Circuit diagram supplying apparatus, circuit diagram supplying method and circuit diagram supplying system

摘要

A circuit diagram supplying apparatus 10, for supplying a user with whole contents of an device system circuit diagram, then requests a server 30 for first-of-all transmission of part-connection-drawing overall circuit diagram data in which connection diagrams LSd are added to a part placement diagram included in the circuit diagram and having electrical component parts PSd arranged therein. Then, after displaying a part-connection-drawing overall circuit diagram based on the transmitted and received part-connection-drawing overall circuit diagram data, the circuit diagram supplying apparatus 10 requests the server 30 for sequential transmission of circuit-element-drawing divisional circuit diagram data (a)-(e).

主权项

1. A circuit diagram supplying apparatus that acquires, from a server, a circuit diagram for a device system including a plurality of electrical components and displays the circuit diagram on a display unit, the circuit diagram supplying apparatus comprising:
upon receiving specification of a device system as a supply object of the circuit diagram, a transmission requester configured to request the server for transmission of circuit diagram drawing data for displaying an image of the circuit diagram of the specified device system, wherein the circuit diagram drawing data includes part placement drawing data for displaying an image of a part placement diagram locating electrical component part diagram for each electrical component included in the specified device system, and remaining circuit-diagram-element drawing data for displaying an image of remaining circuit diagram elements other than the electrical component part diagram in association with a drawing position of the electrical component part diagram in the part placement diagram, and a display controller configured to display an image of the circuit diagram on the display unit based on the circuit diagram drawing data received from the server, wherein the transmission requester: requests the server for transmission of at least the part placement drawing data of the circuit diagram drawing data for the specified device system, and after request of transmission of the part placement drawing data, requests for transmission of the remaining circuit-diagram-element drawing data in transmission units of divided drawing data, the transmission units of divided drawing data being different portions of the remaining circuit-diagram-element drawing data that are individually received from the server and are a result of dividing the remaining circuit-diagram-element drawing data in units of a display area displayable on the display unit, and the display controller after displaying an image of, on the display unit, the part placement diagram based on the part placement drawing data received from the server, displays an image based on the divided drawing data divided-circuit-diagram drawing data received in the transmission units by superimposing on the part placement diagram being displayed on the display unit, and when sequentially receiving the remaining circuit-diagram-element drawing data in transmission units of the divided drawing data, receives data for calculating a ratio of the received divided drawing data to the whole remaining circuit-diagram-element drawing data to be sequentially received, and displaying an image of the calculated ratio on the display unit.
