The data relating to each dryer is returned from the DTC in accordance with the priority order, and the data communication ends when the data end code (デ ー タ) is returned from the DTC in response to the next data request (a).

By the way, in Tables 10 and 11, the misfiring described above, and the misfiring which is determined to be abnormal when the misfiring and ignition during the drying operation are repeated or when the misfiring cannot be reignited, In the case of both abnormalities, five consecutive operations are set as a criterion for the occurrence of an abnormality in order to prevent accidents, but the ignition operation is unstable and is often not based on the abnormality of the device related to the ignition. . If the rotation speed of the drum motor is out of the proper range, it is determined that the rotation is abnormal. In some cases, it may not be based on device malfunction.

In the remote management system according to the present invention, as described later, when a trouble is detected in the dryer and a flag is set, a request for clearing the flag is transmitted from the central unit of the management company, and the drying is performed. The machine can be reset. Further, the type of the detected trouble is determined, and it is determined whether or not the flag can be cleared according to the determined type. Further, when the flag is set, the operation of the dryer is automatically stopped, and when the flag is cleared, the operation is automatically restarted. This allows you to reset the dryer without dispatching a clerk,
The occurrence of an accident related to resetting and restarting operation is avoided, the store is unmanned, and management costs are reduced.

On the other hand, by the DTC arranged in each store,
As described later, data is periodically collected and stored from the dryer, and data is collected from the dryer and transmitted to the central unit in response to a request from the central unit of the management company. In addition, when there is a request from the central unit, data from the dryer is transmitted to the central unit in preference to periodic data collection. As a result, a microcomputer having a small storage capacity can be used for the dryer, so that the cost of the apparatus is reduced and the state of the dryer can be managed in real time.

FIG. 17, FIG. 18, FIG. 19 and FIG. 20 are flowcharts showing the operation procedure in the central unit of the remote management system according to the present invention.

Will be displayed.

If the operation monitor screen is displayed in steps S13 and S16 described above, step S
The process proceeds to step S21, and it is determined whether or not the user has selected to cancel the trouble on the operation monitor screen (step S21). Then, when the cancellation of the trouble is selected, the type of the trouble related to the selection of the cancellation is the trouble type (for example, E1, E2, or E7 shown in Tables 10 and 11) stored in the canceled trouble type storage unit of the central device in advance. ) To determine whether or not release is possible (step S22). If both are of the same type, the line is connected to immediately transmit a release request to the DTC (step S25). If the types are not the same in step S22, that is, if it is determined that the release is not possible, a screen is displayed to prompt the attendant to input a release confirmation key, and the process waits until there is a key input (step S23). If there is a key input, it is determined whether or not the key is a release confirmation key (step S24). If it is a release confirmation key input, the flow proceeds to step S25, and if not, the flow returns to step S1.

When the line is connected in step S25, the central device sets the value of its own device counter to 1 (step S26), and the value of the device counter is the same as the dryer number for which trouble has been selected. It is determined whether there is any (Step S27), and if they are the same, the counter value is added to the trouble clearing request and transmitted to the DTC (Step S28), and after the clearing completion response is received, the value of the device counter is incremented by one. It increases (step S29). If they are not the same, the process skips to step S29 and increments the value of the device counter by one. Then, the value of the device counter is compared with the total number of dryers at the Landry store (step S30), and the operations from step S27 to step S29 are repeated until the values match, and when they match, the line is disconnected (step S31). And return to step S1.

Return to 0.

When these operations are completed, the connection state of the line is determined (step S291). If the line is disconnected by the central unit, the process returns to step S200, and if not, returns to step S220.

FIG. 33 and FIG. 34 are flowcharts showing the operation procedure in the dryer of the remote management system according to the present invention. The microcomputer of the dryer reads the value set by the dip switch and stores it (step S300). Then, it is determined whether there is a data transmission request from the DTC (step S301). If there is no request, control of the dryer operation and processing of data taken from each sensor are performed (step S302), and the process returns to step S301.

On the other hand, when a data transmission request is received from the DTC, it is determined whether or not its own address is included in the command related to the request (step S303). If the own address is included, the command is a trouble monitor request (step S304), a remaining operation time request (step S306), a sales amount request (step S308), or a device setting request (step S308). S310) is determined, transmission of each data of the presence / absence of trouble such as equipment abnormality and theft, and data of operation / stop (Step S305) is made in response to the trouble monitor request, and the current time is sent in response to the remaining operation time request. Of remaining operation time data (step S307)
In response to the sales amount request, the current sales amount data is transmitted (step S309), and in response to the device setting request, each setting data is transmitted (step S311), and the process proceeds to step S302.

It is determined whether the command including the own address is a trouble clearing request (step S312).
If so, the flag set as the trouble detection flag in the microcomputer is cleared (step S313), and the operation of the dryer is restarted (step S314).
). After restarting the operation, the process proceeds to step S302 to control the dryer operation and process the data taken from each sensor. If it is not a trouble clearing request in step S312, the process proceeds to step S302 through step S302.
Return to 301.
