Abstract

PURPOSE:To grasp aging or abnormality of the entire system easily by taking out various state signals from various objective machines through a plurality of monitors, collecting the state signals periodically on a transmission path and displaying them systematically. CONSTITUTION:State signals of objective machines 1 are fed on a digital signal line 2a, an analog signal line 2b and a pulse signal line 2c to a plurality of monitors 3 for monitoring various objective machines, e.g. objective machines 1 mounted on each car composing a train. A transmission controller 5 installed in a monitoring center remote from each car collects state signals from the monitors 3 on a transmission line 4 sequentially and periodically through operation of a console 8. Thus collected signals are then displayed on a display 6 is predetermined format for each car while furthermore printed on a printer 7. According to the system, aging or fault of the entire system including the transmission line 4 can be grasped easily and the cause of abnormality can be searched easily.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention is a method for collecting monitor information that is applied, for example, to monitoring the condition of each vehicle equipment during sacrificial work during a train completion inspection. Regarding the system.

(Conventional technology) During the sacrificial work performed during final train inspections, each vehicle equipment and monitor device are connected by approximately 100 signal lines, and various status signals (digital signals, analog signals, pulse signals, etc.) are connected to each vehicle equipment and monitoring device. (a mixture of formats) is collected by a monitor device, and becomes monitor information for diagnosing whether each vehicle device is operating normally.

(Problems to be Solved by the Invention) In the above-mentioned conventional technology, when there is a failure on the vehicle equipment side and the signal cannot be output to the monitor device, or when there is a problem on the signal line side and the signal is not output normally to the monitor device. In some cases, it may not be possible to import data, so it may be necessary to check whether each vehicle device is at fault.
It was not easy to determine whether the signal line was bad or the signal acquisition conditions of the monitor device were bad, but it took a considerable amount of time to find the fault. In particular, in order to check whether each vehicle device and the monitor device are correctly connected by signal lines, long cables are prepared and the conduction is checked using a tester, etc., which is inefficient and inefficient. there were.

This invention was made in view of the above-mentioned conventional problems, and its purpose is to collectively display on the screen the signals taken in from each target device (vehicle equipment in the above example) to the monitor device, and to The purpose of the present invention is to configure the system so that it can be easily confirmed whether or not signals are being received normally from the source.

[Structure of the invention]

(Means for Solving the Problem) The monitor information collection system of the present invention includes a plurality of monitor devices that capture various status signals from various target devices, and is connected to these monitor devices via a transmission line, so that each monitor device collects and a display device that periodically collects and systematically displays the acquired status signals.

(Function) By monitoring the display on the display device, it is possible to easily determine whether each monitor device is properly receiving the status signal from each target device.

(Embodiment) FIG. 1 shows the configuration of a monitor information collection system according to an embodiment of the present invention. There are various types of vehicle equipment 1 as target equipment, and each of the multiple monitor devices 3 has a plurality of vehicle devices 1, and each monitor device 3 has a digital signal line 2a, an analog signal line 2b, and a pulse signal line. 2c etc. to each vehicle equipment 1, and the vehicle equipment 1
Retrieve various status signals from.

Each monitor device 3 is coupled to a transmission control device 5 via a transmission path 4 . The transmission control device 5 is installed in a monitoring center separate from each vehicle, and is equipped with a display device 6, a printer 7, a console 8, and the like.

The transmission control device 5 sequentially collects monitor information (various status signals taken in from the vehicle equipment 1) from each monitor device 3 at a preset period, and transmits the monitor information for each vehicle as shown in FIG. Display systematically in format.

In the display format of the second country, 16 is an area for displaying the vehicle number, 17 is an area for displaying the name of the digital signal, 18 is an area for displaying the on/off status of the signal corresponding to the digital signal name 17, and 19 is Anna 17
20 is an area that corresponds to one analog signal name and the amplitude value of that signal is converted into a digital value and displayed as a numerical value. 21 is an area that displays the name of a pulse signal. 22 is a pulse This is an area where the frequency, period, etc. of the signal corresponding to the signal name 21 are digitally converted and displayed in numerical values.

In this way, a large number of status signals collected by the monitor device 3 are classified into signal formats such as digital, analog, pulse, etc., and are systematically displayed all at once.

Furthermore, since this display screen is sequentially switched at a constant cycle for each vehicle number, by monitoring the display contents, the overall signal collection status of each vehicle device 1 and each monitor device 3 can be grasped.

Note that the above-mentioned monitor information collection system can be applied and developed into the following system.

(1) A constant monitoring system that is incorporated into a monitor device to grasp the movement of each vehicle device and monitor any errors in the sequence of the device.

(2) A system that is combined with an expert system and indicates processing methods depending on the severity of the failure.

(3) Other equipment (VVVF inverter, S ■■ equipment, etc.)
A transmission line connects the device and a monitor device, and the status of the signal line of other equipment is sent to the display device via the monitor device and displayed.

〔Effect of the invention〕

As explained in detail above, in the monitor information collection system of the present invention, various status signals collected from target devices using a plurality of monitor devices are periodically collected on a display device and systematically displayed. Therefore, by monitoring the display, it is possible to grasp the overall status of each monitor device, each target device, and the numerous signal lines connecting them over time, making it extremely easy to find the cause when an abnormality occurs. It becomes easier.
