Description

This invention generally relates to a technology for collecting data related to passenger conveyors. Escalators are equipped with numerous monitoring sensors to detect escalator malfunctions, including emergency stop buttons, step chain breakage detection devices, and handrail stop detection devices. These monitoring sensors are also installed inside the escalator, including in the drive components such as steps and chains. When obtaining measurement data from monitoring sensors via wired connections, there is a risk of the wiring becoming entangled in nearby moving parts such as chains. To address this, a method has been proposed in which measurement data is transmitted wirelessly from a wireless sensor terminal to a data acquisition device, and then via communication lines such as telephone lines and internet lines to a monitoring system located remotely (see Patent Document 1).

The following describes in detail one embodiment of the present invention. However, the present invention is not limited to this embodiment. This embodiment relates to a passenger conveyor system that collects data using the steps of a passenger conveyor. The passenger conveyor can be an escalator, an automated line, or the like. In this passenger conveyor system, data acquisition devices are installed on the steps of the passenger conveyor. The data acquisition devices collect data related to the passenger conveyor when the communication quality with various sensors installed on the passenger conveyor improves (for example, when it comes within a predetermined distance, or when the radio wave strength exceeds a predetermined value). Furthermore, the data acquisition devices provide measurement data to a communication device (which may also be an anomaly detection device) that notifies the monitoring system of the monitoring center of the data related to the passenger conveyor when the communication quality improves. According to the above configuration, data related to the passenger conveyor is transmitted and received with high communication quality, enabling remote monitoring by the monitoring system. In the following explanation, "interface device" may refer to one or more communication interface devices. These one or more communication interface devices may be one or more identical devices, or two or more different devices. Furthermore, in the following explanation, "memory" refers to one or more memory devices, which are typically main memory devices. At least one memory device in the memory may be a volatile memory device or a non-volatile memory device. Furthermore, in the following explanation, "persistent storage device" may refer to one or more persistent storage devices, which are examples of one or more storage devices. Persistent storage devices are typically non-volatile storage devices (e.g., auxiliary storage devices), such as HDDs (Hard Disk Drives), SSDs (Solid State Drives), NVME (Non-Volatile Memory Express) drives, or SCMs (Storage Class Memory). Furthermore, in the following explanation, "storage device" may refer to at least the persistent storage device among memory and persistent storage devices. Furthermore, in the following explanation, "processor" may refer to one or more processor devices. At least one processor device is typically a microprocessor device such as a CPU (Central Processing Unit), but may also be other types of processor devices such as a GPU (Graphics Processing Unit). At least one processor device may be single-core or multi-core. At least one processor device may be a processor core. At least one processor device may be a broadly defined processor device, such as a circuit that is a collection of gate arrays according to a hardware description language that performs some or all of the processing (e.g., FPGA (Field-Programmable Gate Array), CPLD (Complex Programmable Logic Device), or ASIC (Application Specific Integrated Circuit)).
