Claims (3)

1. 1. A device operation management system that manages operation of a device, the device operation management system comprising: A signal tower lighting detection unit that detects a lighting state of a signal tower that outputs a signal indicating at least whether the device is operating or not operating; a door opening/closing detection unit that detects opening/closing of a door of the device; a PC power supply detection section that detects ON or OFF states of a plurality of PCs used in the apparatus; A platform signal collection unit for collecting signals from the signal tower lighting detection unit, the door opening/closing detection unit, and the PC power detection unit; A monitoring state determination means for determining the operating state of the device with respect to the operation or non-operation and determining whether the device is normal or not, based on the signal from the platform signal collection unit; a monitoring state history storage means for storing the determination result of the monitoring state determination means as a monitoring state history, and And a notification means for notifying when it is determined that the device has changed to the predetermined monitoring state based on the monitoring state history.
2. 2. The device operation management system according to claim 1, wherein, The notification means notifies the device when it is determined that the operation of the device is completed and the device is abnormal.
3. 3. The device operation management system according to claim 1 or 2, wherein, The lighting detection signals of the signal tower are divided into a stop, an operation and a stop, and the stop is divided into an abnormal stop and an operation preparation stop, and the abnormal stop is determined when the operation is stopped and the operation preparation stop is determined when the operation is stopped.

Description

Equipment operation management system Technical Field The present invention relates to an apparatus operation management system that monitors and manages an operation status and the like of an apparatus. Background Efficient use of the system is required in various devices, and various proposals have been made for a system for grasping the operation condition. Patent document 1 discloses a system that acquires operation information of a plurality of test devices and detects the operation rate of the test devices. In this system, a more appropriate operation rate is obtained by taking the operation state of a specific machine in the equipment such as the rotation speed of the motor as a condition. Patent document 1 Japanese patent application laid-open No. 2019-200051 Disclosure of Invention Here, in the operating condition of the equipment, in addition to the condition that only the signal is monitored, there is a condition that an operator must go to a site for confirmation. In this case, a system capable of appropriately notifying the operator is desired. The device operation management system includes a tower lighting detection unit that detects a lighting state of a tower that outputs a signal indicating at least whether a device is operating or not, a door opening/closing detection unit that detects opening/closing of a door of the device, a PC power supply detection unit that detects opening/closing states of a plurality of PCs used in the device, a platform signal collection unit that collects signals from the tower lighting detection unit, the door opening/closing detection unit, and the PC power supply detection unit, a monitor state determination unit that determines an operating state of the device with respect to whether the device is operating or not based on the signals from the platform signal collection unit, and determines whether the device is normal, a monitor state history storage unit that stores a determination result of the monitor state determination unit as a monitor state history, and a notification unit that notifies when it is determined that the device is changed to a predetermined monitor state based on the monitor state history. The notification means can notify when it is determined that the operation of the device is completed or the device is abnormal. The lighting detection signals of the signal tower are divided into a stop, an operation and a stop, and the stop is divided into an abnormal stop and an operation preparation stop, and the abnormal stop can be determined when the operation is changed from the stop to the stop, and the operation preparation stop can be determined when the operation is changed from the stop to the stop. Effects of the invention According to the device operation management system of the present invention, the state can be determined based on the change in the monitored state, and thus, an appropriate device condition determination can be performed. In addition, in a predetermined situation, the notification means can notify the operator or the like. Drawings Fig. 1 is a block diagram showing a configuration of a device operation management system 100 according to the present invention. Fig. 2 is a diagram showing an example in which the platform signal aggregation unit is composed of a sub-platform signal transmission unit and a main platform signal aggregation unit. Fig. 3 is a flowchart illustrating an operation of the device operation management system according to the present embodiment. Detailed Description Hereinafter, embodiments of the present invention will be described with reference to the drawings. The following embodiments are not limited to the present invention, and a configuration in which a plurality of examples are selectively combined is also included in the present invention. "System configuration" Fig. 1 is a block diagram showing a configuration of a device operation management system 100 according to the present invention. In this example, the device is an automobile development device. The signal tower is arranged on the equipment. The signal tower displays the operating condition (operation or non-operation) of the equipment by lighting the lamp, and is turned "off" in the rest state in which the power supply is turned off, and is turned "red" when the equipment is abnormal or is ready (ready state at the start of operation)/is changed (ready state such as change of the model of the object), and is turned "orange" in the normal operation.
