[0031] First, based on Figure 1 ~ Figure 4 , the first embodiment of the measurement system of the present invention will be described. likefigure 1 As shown, the measurement system 10a according to the first embodiment is mainly composed of a system support panel 11, a CPU 20, a master device 30, a node 40, a slave device 50, a sensor unit 60, and the like.

[0032] The system support panel 11 is a device rack on which several units or circuit boards can be installed, and is sometimes called a system rack. The system support panel 11 is generally configured such that a metal plate is attached to a metal frame so as to cover the top, bottom, and side surfaces, and its front or rear access surface can be opened to the outside space. In the first embodiment, units such as the CPU 20 , the master device 30 , the node 40 , and the slave device 50 or circuit boards can be accommodated. In addition, the system support panel 11 corresponds to a "casing" described in the claims. A...

Abstract

The present invention provides a measurement system capable of reducing the size of a device or saving installation space. In the measurement system (10a) according to the first embodiment, data communication between a plurality of nodes (40a to 40n) and a CPU (20) is performed via a master device (30) and a slave device (50a to 50n) in a system support panel (11) by wireless connection without using a cable. Therefore, there is no need to provide cables for data communication between them, and there is no need to secure a space for accommodating cables in the housing. Therefore, the volume ofthe system support panel (11) can be reduced. Accordingly, it is possible to reduce the size of the device or save installation space.

Description

technical field [0001] The invention relates to a measurement system with several control units connected to several sensors. Background technique [0002] A measurement system including a plurality of control units connected to a plurality of sensors includes, for example, a "liquid level measurement system" disclosed in Patent Document 1 below. In this system, several detection control circuits connected to electrode pairs as sensors are provided, and these several detection control circuits are connected to a computing circuit constituted by a personal computer, for example (Patent Document 1: Paragraph 0021). [0003] 〔Patent Document〕 [0004] Patent Document 1: Japanese Patent Laid-Open No. 2013-205311 [0005] As in the "liquid level measuring system" disclosed in the above-mentioned Patent Document 1, in a measuring system including several control units, the several control units and the upper-level controller that processes the sensor data to be output from these...
