Problems solved by technology

[0002] Depending on the user's operating conditions, the operation buttons of the elevator may damage the plastic parts or terminals and cause malfunctions.
In addition, the car door safety device mainly uses the reflection of light to operate, so it may malfunction due to the adhesion of dust or the existence of shielding objects. The car door safety device has a sensor installed at the end of the elevator door. And sensor components that detect passenger boarding and landing
In addition, in the operation button and car door safety device, the terminals or wiring may have poor contact due to vibration or aging
In the past, when there was no regular inspection by elevator maintenance personnel or notification from users, such malfunctions and poor contacts were not detected and were shelved.

Embodiment approach 1

[0032] In Embodiment 1, a method of detecting a failure of a button device will be described. figure 1 It is a figure which shows the structure of the surrounding area to which the elevator inspection apparatus and this elevator inspection apparatus are connected according to Embodiment 1 of this invention. In the following description, the "operating state" of the elevator refers to a state in which the elevator equipment is in operation and can respond to a passenger's car call. In addition, the "boarding and landing state" of the elevator refers to the fact that the passenger calls the car at the landing, the car moves to the landing where the passenger is waiting, the passenger rides in the car, the car moves to the destination floor, and the passenger gets off the car. The status up to the boarding point of the destination floor. figure 1 The elevator inspection device 1 shown has: a state collection unit 2, which collects and transmits the operating status information o...

Embodiment approach 2

[0052] In Embodiment 2, a method of detecting a malfunction of the car door safety device will be described. In the present embodiment 2, until the state recorder 3 records the passenger's boarding and disembarking state information (S5), the figure 2 are treated the same. The abnormality determination unit 5 calculates the number of operations of the car door safety device based on the passenger boarding and disembarking status information stored in the status storage unit 4 .

[0053] Figure 12 It is a diagram showing an example of the abnormality detection condition management table stored in the abnormality detection condition storage unit 6 . Car door safety device 14 in Figure 6 In the shown device management table is the device number "10". Therefore, calculate Figure 12 The device number of the abnormality detection condition management table shown is "10" and the operation frequency of the elevator state. according to Figure 12 In the abnormal detection co...

Embodiment approach 3

[0055] The elevator inspection device described in Embodiment 3 can not only detect failures as shown in Embodiments 1 and 2, but also can additionally record abnormality detection conditions in the abnormality detection condition storage unit according to the contents of the status storage unit. Conditions.

[0056] Figure 13 It is a flowchart explaining the operation|movement of the elevator inspection apparatus concerning Embodiment 3 of this invention. In Embodiment 3, until the state recording unit 3 records the boarding and disembarking state information (S5), the figure 2 are treated the same. After S5, the state recording unit 3 judges whether or not the number of recordings of the boarding and disembarking state information has reached a predetermined number of times of learning (S16). When the branch is "No" in S16, that is, when the recording times of boarding and disembarking state information has not reached the prescribed number of times of learning, the abn...

Abstract

This invention addresses the problem of providing an elevator inspecting device that allows a failure that affects elevator operations to be automatically detected. An elevator inspecting device (1), which detects abnormalities for an elevator that is raised and lowered by an elevator controlling device (11), is configured to comprise: a status collecting unit (2) to collect information on the operational status of the elevator from the elevator controlling device (11); and an abnormality reporting unit (7) to report abnormality information to be displayed on a landing display device (15) and a device number of a monitored device that is information identifying an elevator device determined to be abnormal from the operational status collected by the status collecting unit (2) to the landing display device (15) via the elevator controlling device (11).

Description

technical field [0001] The invention relates to an elevator point inspection device for automatically detecting elevator faults. Background technique [0002] The operating buttons of the elevator may damage the plastic parts or terminals depending on the operation status of the user, resulting in malfunction. In addition, the car door safety device mainly uses the reflection of light to operate, so it may cause malfunction due to the adhesion of dust or the existence of shielding objects. The car door safety device has a sensor installed at the end of the elevator door. And sensor components that detect passenger boarding and landing. In addition, in the operation buttons and car door safety devices, terminals or wiring may have poor contact due to vibration or aging. In the past, there were also cases where such malfunctions and contact failures were left undetected without periodic inspection by elevator maintenance personnel or reports from users. However, in recent y...
