Abstract

PROBLEM TO BE SOLVED: To find a cause of a failure at a working site without a service enginner taking a computer to the working site as well as to centralizedly control an overall parking area. SOLUTION: When abnormality occurs in a parking area, a data of a sensor, or the like at the time of a failure is transmitted to a host computer on the central side through a public line in a system to diagnose a large number of the failures of the parking area. Thereafter, in accordance with the data, a cause of the failure is assumed from the data of the sensor, or the like and question items and the cause of the failure are transmitted to the parking area where the failure occurs at a host computer 40.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parking lot failure diagnosis system capable of diagnosing an abnormality or a failure of a multistory parking lot in a remote control room.

[0002]

2. Description of the Related Art A remote failure monitoring system for a parking lot is
Although it has been actually used in various parking lots, there is no case where full-scale remote failure diagnosis is performed.

Normally, when a failure occurs, a service engineer of a parking lot manufacturer is contacted and a service engineer goes to the parking lot to identify the cause of the failure and repair it.

[0004]

However, in the case of a complicated parking system such as a large-scale mechanical parking lot, it is impossible to estimate the cause of the failure only by the abnormal message, and it is very long to identify the cause. There is a problem that it takes time.

As a failure diagnosis system for a small-scale parking lot, a service engineer may bring a personal computer to the site, or use a permanent personal computer to detect the presence / absence of abnormalities of various sensors. While checking, and diagnosing by identifying the failure location, since parking lots are scattered all over the country, each service center,
There is a problem that it is uneconomical to have a failure diagnosis computer according to the type of parking lot, and it is difficult to centrally manage diagnostic knowledge. Further, if there is no failure diagnosis computer, there is a problem that failure diagnosis cannot be performed.

[0006] Therefore, an object of the present invention is to solve the above-mentioned problems, to centrally manage all parking lots, and to let the service engineer know the cause of the failure without having to bring a computer to the parking lot. To provide a diagnostic system.

[0007]

In order to achieve the above object, the invention of claim 1 is a system for diagnosing a failure of a large number of parking lots, and when an abnormality occurs in the parking lot, a sensor or the like at the time of the failure. Data is sent to the host computer on the monitoring center side via the public line, and based on this, the host computer estimates the cause of failure from the data of the sensor, etc., and asks questions and the cause of failure to the parking lot where the failure occurred. It is a parking lot failure diagnosis system to be sent to.

A second aspect of the present invention is the parking lot failure diagnosis system according to the first aspect, wherein the transmission to the parking lot is output to a FAX receiver or printer in the parking lot.

According to the third aspect of the present invention, the failure diagnosis is performed by using an expert system, and the cause of the failure is created in a hierarchical hierarchy in the form of a question tree of YES and NO formats, and the question tree is transmitted to the parent machine in the parking lot. 3. The parking lot failure diagnosis system according to claim 1, wherein the parking lot failure diagnosis system outputs to a FAX or a printer device connected to the master unit.

According to a fourth aspect of the present invention, the parking lot has a slave unit monitoring a device sequencer for controlling the devices in the parking lot, a host computer connected to the host computer through a public line, and a failure occurs. Occasionally, the slave unit receives the operating status of the sensor or actuator of the device sequencer, and the master unit issues a message indicating that a failure has occurred, the parking lot number, the terminal number of the slave unit that detected the failure, and the device for each device controlled by the slave unit. The number, the alarm number for identifying the faulty device, and each sensor data corresponding thereto are transmitted together as one packet, and the host computer side uses the information of the parking lot registered in advance to identify the parking lot. The parking lot failure diagnosis system according to any one of claims 1 to 3, wherein a failure position and a device are determined and a failure diagnosis is performed from each sensor data.

According to the above configuration, when an abnormality occurs, the failure data is transmitted to the host computer on the monitoring center side, the host computer diagnoses the failure, and the result is transmitted to the parking lot by FAX or the like. As a result, the result of the failure diagnosis can be obtained on-site and the cause can be identified in a short time without bringing any equipment for failure diagnosis.

Further, the failure diagnosis computer can be integrated into one unit through all the parking lots, and the information can be centrally managed. Especially for diagnostic knowledge, since the expert system is used, it is possible to frequently update and upgrade the version by referring to the failure situation and countermeasures even after operation, and by centralizing it, immediately apply this to all parking lots. It becomes possible.
