An onboard equipment network system comprises a radar core device, a GPS core device, an echo sounder core device and a sonar core device and display devices which are connected to a network through a hub. Each core device includes a detecting section or a positioning section, as well as a control section, a power supply section and a data transmitter for transmitting detecting signals or positioning signals, while each display device includes a command section for transmitting command data to the individual core devices for setting their operating conditions and a display section for displaying image data received from the individual core devices. The command data is transmitted using Transmission Control Protocol (TCP) while the image data is transmitted using User Datagram Protocol (UDP).

1. Field of the Invention
The present invention relates to an onboard equipment network system including at least one detecting apparatus, such as a radar, a sonar or an echo sounder, and/or a positioning apparatus, such as a receiver for the Global Positioning System (GPS receiver), and a common display device, wherein image data obtained by the detecting apparatus and/or the positioning apparatus is transmitted through a network and displayed on the display device.
2. Description of the Background Art
FIG. 1 is a block diagram of an onboard equipment network system according to a first embodiment of the invention;
FIG. 2 is a block diagram of a radar of the onboard equipment network system according to the first embodiment;
FIG. 3A and FIG. 3B are flowcharts showing startup and shutdown sequences of a detecting section, respectively;
An onboard equipment network system according to a first embodiment of the invention is now described in detail with reference to FIGS. 1 through 13.
FIG. 1 is a block diagram of the onboard equipment network system according to the first embodiment of the invention, in which solid arrows indicate command data for controlling power on/off and operating conditions of individual system elements while broken arrows indicate detection signals and positioning signals as well as such image data as detection data and positioning data for ons-creen display. As shown in FIG. 1, the onboard equipment network system comprises a radar, a GPS receiver, an echo sounder, a display device 21 and a display device 24.
The radar includes a radar antenna 1 for transmitting and receiving radio detection signals and a radar core device 2. The core device 2 includes a radar detecting section 3 which generates detection data, or radar image data, from the detection signals, a control section 4 for controlling transmission of the radar image data, operating conditions of the detecting section 3 and on/off states of a power supply section 5, and the power supply section 5 for feeding electric power to the detecting section 3 and the control section 4.
