no. 1 Embodiment approach ＞

[0017] figure 1 It is a block diagram showing a configuration example of an elevator remote monitoring system having a program erasing device 10A according to the first embodiment. Such as figure 1 As shown, the elevator remote monitoring system has a program erasing device 10A, a remote monitoring device 20 , an elevator control panel 30 and a remote monitoring server 40 . The program erasing device 10A, the remote monitoring device 20 and the elevator control panel 30 are installed at the installation site of the elevator. The remote monitoring server 40 is set in the monitoring center. The remote monitoring device 20 installed in the elevator installation site and the remote monitoring server 40 installed in the monitoring center are connected via the communication line 50 so as to be able to communicate.

[0018] The remote monitoring device 20 stores a remote monitoring program 21 for executing processing necessary for remote monitoring of an elevator. The remote moni...

no. 2 Embodiment approach ＞

[0035] Next, a second embodiment will be described. In this embodiment, setting of the set time Ts and resetting of the counter 15 are performed using a maintenance terminal carried by a maintenance worker. In addition, in the above-mentioned first embodiment, the counter 15 counts the time based on the clock generated inside the program erasing device 10A, but in this embodiment, it is based on the time information acquired from the elevator control board 30. The time is counted. Hereinafter, common reference numerals are assigned to the same constituent elements as those of the above-mentioned first embodiment, and description thereof will be appropriately omitted, and only the characteristic parts of the present embodiment will be described.

Abstract

The present invention provides a program erasing device and a program erasing method, which can effectively prevent disadvantages such as technical information leakage caused by the analysis of the remote monitoring program even when the remote monitoring device cannot be recovered after the maintenance contract ends . The program erasing device of the embodiment includes a timer and a control unit. The timer sets a set time based on the intervals at which the maintenance work of the elevator is performed, and outputs a control signal when the counted time reaches the set time. The control unit erases the remote monitoring program stored in the remote monitoring device installed at the installation site of the elevator when the timer outputs the control signal.

Description

technical field [0001] Embodiments of the present invention relate to a program erasing device and a program erasing method. Background technique [0002] The maintenance of the elevator is carried out based on the maintenance contract. During the period of the maintenance contract, remote monitoring of the elevator and regular on-site maintenance work by maintenance operators are generally carried out. After signing the maintenance contract, in order to enable remote monitoring of the elevator, a remote monitoring device will be installed at the installation site of the elevator, and the remote monitoring device will be connected to the remote monitoring server installed in the monitoring center via a communication line. According to the pre-stored remote monitoring program, the remote monitoring device, for example, collects information for diagnosis from the elevator control panel and sends it to the remote monitoring server, uses the collected information to perform sel...
