Detection device, physical quantity measuring device, detection system, and electronic device

Abstract

The invention provides a detection device, a physical quantity measuring device, a detection system, and an electronic device, and detection data of a proper acquisition timing can be obtained and output to an external device. The detection device includes: a detection circuit that performs detection processing based on a signal from a physical quantity transducer and outputs detection data; an interface that has communication connection with an external device and outputs the detection data to the external device; and a processing circuit. The processing circuit outputs the detection data acquired from the detection circuit at a common acquisition timing common to at least one other detection device and the own detection device, to the interface in a data transmitting order of own detection device.

Description

technical field [0001] The present invention relates to a detection device, a physical quantity measurement device, a detection system, electronic equipment, a mobile body, and the like. Background technique [0002] As a technique for communicating with a plurality of sensor devices (physical quantity measuring devices), there is a prior art disclosed in Patent Document 1, for example. This prior art proposes a method of storing device IDs, the number of connected sensor devices, and the output sequence of detection data in a storage unit of a detection device, and performing serial communication between a master device and a plurality of sensor devices. When the master device specifies a common address for multiple sensor devices and issues a read command, the detection data is transmitted in the order of output of each sensor device, so the connection with the master device can be simplified, the number of terminals can be reduced, and the command can be simplified.

Problems solved by technology

[0004] However, this prior art does not consider the timing when multiple sensor devices actually update the detection data, and does not propose at which timing the detection data should be sent to the master device
