Connected to.

  Next, an embodiment of the present invention configured as described above will be described. First, the manager inputs from the master management terminal 3 inspection information on which parts and parts are to be inspected in each process for each manufactured automobile. As a result, the inspection information is transmitted to the inspection master database 11 of the server 2.

  Thus, when inspection information in each process for each automobile manufactured in the inspection master database 11 of the server 2 is set, the inspection portable terminal 5a performs wireless communication with the server 2 in each process. The inspection portable terminal 5 a displays an inspection screen on the liquid crystal display 54 based on the inspection information transmitted from the server 2. And the inspection result of each process is inputted into the inspection screen.

  When a problem is found in the inspection process, a phenomenon input mode is set in which the phenomenon is input to the inspection portable terminal 5a by the operation of the operator. As a result, the phenomenon input mode screen is displayed on the liquid crystal display 54 of the inspection portable terminal 5a.

  On the screen of this phenomenon input mode, data such as the inspection object, the inspection content, the inspection site, the reference, and the measurement value are displayed. The first to fourth windows are displayed on this phenomenon input mode screen. For example, the first window is a failure phenomenon registration window for registering a phenomenon. In this first window, a phenomenon, a part, an occurrence state, a handwritten memo, and a point (points where the occurrence part is indicated by a point) are displayed. The specific contents of the phenomenon are listed in the second window as candidates for the phenomenon. For example, “-”, “large”, “small”, “adjustment failure”, and “not adjusted” are listed as phenomena. “−” Is a case that does not correspond to “many”, “small”, “adjustment poor”, and “not adjusted”. In the third window, site candidates are listed. Note that “-” means that no candidate site is listed.

  Furthermore, candidates for occurrence status are listed in the fourth window. For example, “-”, “secondary failure”, “E / G start-up”, etc. are listed.

  The operator registers the phenomenon by selecting contents corresponding to each item (phenomenon, part, occurrence state,...) Of the first window from the candidates displayed in the second to fourth windows. ing.

  An input button for inputting a handwritten memo and an input button for inputting a point are displayed at the center on the right side of the screen in this phenomenon input mode.

  This input button is operated when the operator manually inputs the part by operating this input button because the candidate for the part is not listed in the third window.

  For example, if a nut and a place where a problem has occurred are input by handwriting with “→”, they are displayed in the window.

  Then, when the “OK” button is clicked, the contents handwritten to the window are input.

  As a result, the screen of the phenomenon input mode is returned to the state displayed on the liquid crystal display 54.

  Here, when the registration button is clicked, the phenomenon set on the phenomenon input mode screen is transmitted to the server 2 (first transmission means).

  The server 2 performs the process shown in the flowchart of FIG. That is, the server 2 determines whether or not a handwritten memo has been input from the mobile terminal 5a (step S1). If it is determined “YES”, the handwritten memo is stored in the inspection result database 12 (step S2). Then, in the daily work, a process of listing up the input handwritten memo is performed (listing means) (step S3). Hereinafter, this is referred to as a handwritten memolist.

  The phenomenon data stored in the inspection result database 12 is appropriately called from the repairing portable terminal 5b carried by the operator in a subsequent process, for example, the repairing process, and transmitted to the portable terminal (second transmitting means) ). Then, it is displayed on the liquid crystal display 54. Thereby, the repair work in the repair process can be smoothly advanced.

  By the way, the handwritten memo list lists and stores the inspection date, inspection job, inspection object, inspection content, part, and handwritten memo for each line. Then, by selecting an arbitrary line, the handwritten memo can be displayed on the liquid crystal display 54 of the portable terminal as shown in FIG.

  Incidentally, the administrator can refer to the handwritten memo list stored in the server 2 from the management terminal 3. Then, by looking at the handwritten memo list, a process for setting an inspection code is performed for a part in which a problem frequently occurs.

  The new inspection code set in this way is detected by the process of step S4 of the server 2. That is, in step S4, it is determined whether the inspection item master has been updated. If it is determined “YES” in step S4, the inspection item master shown in FIG. 7 stored in the inspection master database 11 of the server 2 is updated (step S5).

  As described above, the handwritten memo information input from the inspection portable terminal 5a is automatically listed by the daily processing in the server 2, so that a portable terminal other than the inspection portable terminal 5a, for example, a mobile phone for reworking Handwritten memo information can be appropriately read from the terminal 5b and the shipping portable terminal 5c as necessary. For this reason, the management capability of the server 2 can be significantly improved.

  Furthermore, when a code is input from the master management terminal 3, the inspection item master provided in the master is updated, so that the update lead time for the inspection item master data can be shortened.

  Furthermore, in this embodiment, an inspection portable terminal is used as the inspection terminal, a correction portable terminal is used as the correction terminal, and communication is performed by the wireless communication method via the server 2 and the access point 4. Although described above, the present invention is not necessarily limited to this, and an installation type inspection terminal or rework terminal set by the server 2 and the LAN may be used.
