BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a time recorder, and more particularly to a history information collecting device capable of storing fault information of the time recorder.

[0002]

2. Description of the Related Art In a conventional time clock, when a time card is inserted in an incorrect direction, or when a system initialization error occurs after a power failure is released, a failure occurrence and the content of the failure are displayed on a display unit to notify the user. ing.

[0003]

The conventional time clock displays the occurrence of a failure on the display unit. However, when the power is turned off or the user performs another operation, the displayed content may be erased. Depending on the nature of the failure, repair may be required by a service person. However, if the error message on the display is gone, failure information cannot be obtained, and it takes time to investigate the cause, leading to a reduction in work efficiency.

[0004] In addition, when the time setting is changed or the registered data is deleted due to a user's own erroneous operation, the user may mistakenly recognize that a failure has occurred. In some cases, it is difficult to respond appropriately. Therefore, there is a technical problem to be solved in order to be able to arbitrarily read history information such as trouble information of the time clock and setting operation and to improve the serviceability by enabling an appropriate response. The purpose is to solve the problem.

SUMMARY OF THE INVENTION This invention is proposed to achieve the above-mentioned object. The control unit of a time recorder detects a power failure detection unit and an abnormality of a peripheral unit such as a timer unit and a storage device. Means for monitoring operation information by the setting information input means,
Rewritable nonvolatile memory, control means for storing history information in which time information is combined with power failure information, abnormality information of peripheral devices and setting operation information in the nonvolatile memory, and a read command via an input means. It is an object of the present invention to provide a history information collecting apparatus in a time clock provided with control means for reading history information from the nonvolatile memory and displaying and transferring the history information.

[0006]

[Function] Power failure, peripheral device abnormality, control unit operation abnormality
Occurs, the history information storage control means of the control unit stores the failure data and the occurrence date and time data in a rewritable nonvolatile memory. Even when a setting operation such as a time is performed by an artificial operation, the operation information is stored in the nonvolatile memory.
When a history information read command is input by the input means,
The history information reading control means satisfies the condition specified by the command.
Therefore, the information is read from the non-volatile memory and is displayed on the display means.
Therefore, the information content can be displayed or the information can be displayed on another computer.
Transmit information.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a configuration of a history information collection device in a time clock, an abnormality detection means 3 for notifying a control unit 1 of an operation abnormality of peripheral devices 2, 2,... Such as a timer LSI, and monitoring a power supply voltage to notify when a power failure occurs. Power failure detection means 4 is connected.

When the abnormality is detected by the abnormality detecting means 3 and the power failure detecting means 4, the control section 1 displays the error in the form of an error message or an error code on a display means 5 such as an LED time display section of a time recorder. Then, information such as the date and time of the occurrence of the failure and the items are logged out to the nonvolatile memory 6 such as an EEP-ROM or an EA-ROM.
Further, the control unit 1 constantly monitors a time setting operation and the like performed through the input means 7 such as a key by a setting operation monitoring program, and stores information such as operation items and operation date and time when the operation is performed. Stored in the memory 6.

The causes of the abnormal operation of the time clock are as follows. Data backup error at power failure b. Abnormal system initialization and data recovery at power recovery c. There are abnormal operations of peripheral devices and destruction of stored data due to obstacles such as electromagnetic noise.

[0010] Also, d. The setting change of the time, the ID code, or the like due to an erroneous operation, or the disappearance of data can be given. Any of the fault information a, b, and c and the setting operation information that causes d can be read from the nonvolatile memory 6 by operating the input means 7 and displayed on the display means 5. Further, the display contents may be printed out by the printing means 8 using the print head of the time clock.

When maintenance is required, the input means 7 a. Display of all stored data b. Display of operation abnormality, error occurrence status, and setting operation information within the period specified by the period c. Item content display by item designation d. You can select to display the contents that specify the period and item.

The operation start date and the warranty period can be confirmed from the setting operation information stored in the nonvolatile memory 6 by the date setting operation at the start of use. Although not shown, a communication cable connector may be connected to the control unit 1 so that information stored in the nonvolatile memory 6 can be transmitted to another processing device via the communication cable.

[0013]

According to the present invention, as described in detail in the above embodiment, failure information such as operation abnormality and setting operation information such as setting change are stored in a non-volatile memory. The cause of abnormality occurrence can be confirmed.
Further, when an error occurs in the registration result, it is possible to determine from the stored data whether the cause is an error of the device or an error of the setting operation, etc., so that the time required for investigating the cause is saved, and the service efficiency is remarkably improved. This is a practically valuable device that also contributes to the improvement of reliability.
