Description

This invention relates to a novel terminal block type unit combining a data input/output device (measuring instrument) and a terminal block, and to a monitoring system using the same. Generally, measurement systems employ a configuration where signal lines connected to numerous sensors are collected at a "signal input/output device" via a "terminal block." The terminal block also serves as a contact terminal (output port) for sending control signals to the controlled device (hereinafter referred to as "control device") based on data acquired by the sensors. In other words, numerous signal lines connected to sensors and control devices are collected at a terminal block equipped with numerous contact terminals, and these signal lines are then connected to the signal input/output device via the terminal block. The signal input/output device functions as a measuring instrument (data logger) that records data acquired by sensors, and is connected via an input/output interface to a small, dedicated terminal (measurement terminal) for recording measurement data and controlling the control device, or to a computer (such as a general-purpose computer with a data processing program installed) for processing the recorded data. In other words, if we simplify the physical connection configuration of a typical measurement system, with "sensors or control devices" on the lower end and a computer on the upper end, (a) [Sensor or control device] - [Terminal block] - [Signal input/output device] - [Measurement terminal] - [Computer], or (b) [Sensor or control device] - [Terminal block] - [Signal input/output device] - [Computer] It is expressed as follows. Figure 11(A) is a diagram (photograph) showing the external shape of a conventional signal input/output device 200. As shown in the figure, the signal input/output device 200 consists of a main body 202 and a plurality of terminal units 204 having a large number of contact terminals. Figure 11(B) schematically shows how a conventional signal input/output device 200 electrically connects the contact terminals of the terminal unit 204 and the terminal block 300 with physical signal lines. Each terminal of the terminal unit 204 connected to the signal input/output device 200 is sequentially connected to each upper terminal 302a of the terminal block 300 with an electric wire. On the other hand, each upper terminal 302a of the terminal block 300 is installed facing each lower terminal 302b, and each lower terminal 302b is electrically connected to each terminal of a sensor or control device (not shown). Figure 12(A) shows an example of an electrical wiring diagram inside a control panel. In actual connection work, it is necessary to connect each terminal with wires according to such a wiring diagram. A label is attached to each signal wire that connects to each terminal, and all signal wires must be connected to the correct terminal. Naturally, the more signal wires that are connected to the terminal block, the more complex the wiring becomes. Figure 12(B) is a photograph showing a terminal block with a label attached to each signal line connected to each terminal. In small-scale experiments in laboratories, it's sometimes possible to omit terminal blocks and directly connect "exposed signal lines" to signal input/output devices. However, for continuous operation, including maintenance, it's common practice to first connect the signal lines to the numerous terminals on a terminal block, and then wire each terminal of the terminal block to the input terminals of the signal input/output device. As mentioned above, numerous signal lines are connected to the terminal block and signal input/output devices, making the wiring very complex. These devices often include necessary equipment depending on the system configuration, such as power supplies, circuit breakers, surge protectors (SPDs), and AC adapters. Therefore, they are typically housed in a single enclosure called a control panel. Figure 5(B) is a diagram (photograph) showing the internal configuration of a 64-point measurement enclosure, illustrating an example configuration using a commercially available signal input/output device (M System R3 series). It shows how numerous wires are physically connected to terminals within the enclosure. International release 2020/203672 Figures 1(A) to 1(C) show the external shape of the housing of the terminal block type unit. (A) is a perspective view, (B) is a front view, and (C) is a rear view.Figures 2(A) and 2(B) both show how multiple terminal block-type units are connected together.Figures 3(A) and 3(B) both show how a host device is connected to the other end of a bus cable 24 connected to a terminal block type unit.Figure 4 shows the color changes of the indicator 20.Figure 5(A) shows an example of a conventional 64-point measurement distribution board (Figure 5(B)) consisting of a signal input/output device 200 and a terminal block 300, as explained with reference to Figure 11,
