Abstract
A data communication gateway for a construction machine communication system, the gateway comprising including a first, a second, and a third data interface arranged to be mutually interconnected, where the mutual interconnect is controlled by a gateway electronic control unit, ECU, wherein the first interface is arranged to be connected to a private network of a construction machine, the second interface is arranged to be connected to an attachment network, and the third interface is arranged to be connected to an auxiliary network, wherein the gateway ECU is arranged to receive a request for hydraulic pressure release on the second interface and to forward the request as a hydraulic pressure release signal on the first interface.
Claims19
A data communication gateway for a construction machine communication system, the construction machine using a hydraulic system to power an attachment via an intermediary attachment device, wherein to release the attachment from the intermediary attachment device, the pressure in the hydraulic feed must first be released, the data communication gateway comprising a first data interface, a second data interface, and a third data interface arranged to be mutually interconnected by a mutual interconnect, where the mutual interconnect is controlled by a gateway electronic control unit, ECU,
- wherein the first data interface is arranged to be connected to a private network of the construction machine, the second data interface is arranged to be connected to an attachment network, and the third data interface is arranged to be connected to an auxiliary network,
- wherein the gateway ECU is arranged to receive a request for hydraulic pressure release on the second data interface and to forward the request as a hydraulic pressure release signal on the first data interface, wherein, in response thereto, the construction machine controls the hydraulic feed pressure in response to the request in order to facilitate attachment assembly, wherein the gateway ECU is arranged to be connected to a hydraulic pressure sensor, wherein the gateway ECU is arranged to transmit an acknowledgement signal indicating hydraulic pressure release on the second data interface in response to detecting a pressure drop by the hydraulic pressure sensor.
A construction machine comprising a data communication gateway, the construction machine using a hydraulic system to power an attachment via an intermediary attachment device, wherein to release the attachment from the intermediary attachment device, the pressure in the hydraulic feed must first be released, the data communication gateway comprising a first data interface, a second data interface, and a third data interface arranged to be mutually interconnected by a mutual interconnect, where the mutual interconnect is controlled by a gateway electronic control unit, ECU,
- wherein the first data interface is arranged to be connected to a private network of the construction machine, the second data interface is arranged to be connected to an attachment network, and the third data interface is arranged to be connected to an auxiliary network, wherein the gateway ECU is arranged to receive a request for hydraulic pressure release on the second data interface and to forward the request as a hydraulic pressure release signal on the first data interface, wherein, in response thereto, the construction machine controls the hydraulic feed pressure in response to the request in order to facilitate attachment assembly, wherein the gateway ECU is arranged to be connected to a hydraulic pressure sensor, wherein the gateway ECU is arranged to transmit an acknowledgement signal indicating hydraulic pressure release on the second data interface in response to detecting a pressure drop by the hydraulic pressure sensor.
A method performed by a data communication gateway comprised in a construction machine communication system, the construction machine using a hydraulic system to power an attachment via an intermediary attachment device, wherein to release the attachment from the intermediary attachment device, the pressure in the hydraulic feed must first be released, the gateway comprising a first data interface, a second data interface, and a third data interface arranged to be mutually interconnected, wherein the gateway ECU is arranged to be connected to a hydraulic pressure sensor, where the mutual interconnect is controlled by a gateway electronic control unit, ECU, wherein the first data interface is arranged to be connected to a private network of the construction machine, the second data interface is arranged to be connected to an attachment network, and the third data interface is arranged to be connected to an auxiliary network, the method comprising
- receiving, by the gateway ECU, a request for hydraulic pressure release on the second data interface and
