Embodiment
[0044] Such as figure 1 As shown, the present embodiment provides a schematic diagram of a board and a chassis. The inside of the chassis is a chassis backplane 200, and there are multiple connectors (hereinafter also referred to as second connectors) on the chassis backplane. Each connector 210, 220, 230, 240 are arranged side by side, and each connector 210, 220, 230, 240 is respectively matched with the first connector 110 of a board 100; and preferably, the connector 110 of the board in this embodiment The length of the pins on the chassis is set to be the same, and the pins in each second connector on the chassis backplane are also set to be the same. It should be noted, figure 1 It is only a schematic diagram of the correspondence between the board and the preferred structure of the chassis in this embodiment, and this embodiment is not limited thereto. For example, only one second connector may be provided on the backplane of the chassis as required. If multiple second...

The invention belongs to the technical field of board card communication. For solving the technical problem that whether a board card corresponding to a multi-row-pin connector is reliably connected cannot be detected at a low cost in existing technical solutions of board card in-position detection, the invention provides a board card, a case, a board card communication system and a board card in-position detection method. The board card includes a first connector. The first connector includes at least two detected pins which are in mutual serial connection and are used for detecting whether the board card is in position. Only when the board card is correctly mounted to the case, at least one pin in detection pins is mutually coupled with at least one pin in the detected pins in a case backplane, a detection branch closed by the detection pins and the detected pins is enabled to be formed between the detection pins and the detected pins, and the detection branch includes at least threepairs of coupled pins.
Description
technical field [0001] The present invention relates to the technical field of board card communication, in particular to the technical field of board card in-position detection, and more specifically, to a board card, a chassis, a board card communication system and a board card in-position detection system applied in a DCS system. Detection method. Background technique [0002] In the control system, the communication between boards usually adopts a plug-in card structure, which is usually composed of a backplane (or chassis) and a data board, through the connector on the data board and the connector on the backboard. The connection between the data board and the backplane is realized. Due to the need to support live plugging and unplugging, some important boards must detect whether they are reliably connected to the connectors of the boards (that is, detect in-position signal detection) when they are powered on, so as to determine the connection with the backplane connec...
