FIG. 53 is a sequence diagram in which data communication is performed between the central device and the DTC using a public line, and FIG. 54 is a frame structure diagram of the trouble-solving request described above. As shown in Fig. 54, there is a trouble release request code (c) in the 1st byte, and the 10th and 1st places of the dryer number to release the trouble are written in the lower 4 bits of the 2nd and 3rd bytes, respectively. It is transmitted from the central device to the DTC together with the 4-byte data end code as shown in Fig. 53.

【0060】

On the other hand, if the trouble cancellation is not selected in step S21, the process proceeds to step S100, and it is determined whether the device setting change is selected and requested on the menu selection screen (step S100), and if there is no request, the menu is displayed. On the selection screen, fault diagnosis by the input / output port (I / O port) of the microcomputer is selected and it is determined whether it is requested (step S101). Then, when the request is made, the line is connected (step S102) and the I / O port monitoring process is performed (step S103).

【0061】

FIG. 28 is a flowchart showing the processing procedure of the I / O port monitor. The central unit sends an I / O port monitor request code to the DTC (step S1030) and waits for a response from the DTC (step S1031). When there is a response from the DTC, it is determined whether the response is an exit code (step S1032), and if it is not an exit code, the response data is stored together with the device number (step S1033) and the next data request code is transmitted. (Step S1034). The transmission of the next data request code and the storage of the response data are repeated, and when the response becomes the end code (step S1032), the I / O port monitor process is terminated and the response is returned.

【0062】

When the I / O port monitoring process is completed, the line is disconnected (step S104). The central device is preset with a pattern when the I / O port level of the microcomputer installed in the dryer is normal, and is set as the I / O port level pattern related to the data transmitted from each dryer. By comparing with the normal pattern, the abnormality of each device provided in the dryer is diagnosed (step S105). For example, if the command signal is output from the output port of the microcomputer to drive the device, but the signal from the sensor provided in the device is not input to the input port, the I / O port level pattern Is abnormal, and the device related to the abnormal pattern is diagnosed as abnormal. Then, the screen of the diagnosis result is displayed on the display device of the central device (step S106), and the process returns to step S1.

The DTC control unit sets the value of the equipment counter to 1 (step S271) and collects the data related to the dryer with the number corresponding to the value of the equipment counter (step S272). Then, the collected data is transmitted to the central device (step S273) and waits until the next data request from the central device is received (step S274). When the next data request is received, the value of the equipment counter is incremented by one (step S275), the value of the equipment counter is compared with the number of dryers (step S276), and the value of the equipment counter becomes the number of dryers. Repeat the data transmission until. When the value of the equipment counter and the number of dryers become the same, the DTC control unit transmits a data end code (step S277) and returns to step S220.

【0082】

42 and 43 are flowcharts showing the operation procedure of the DTC in response to the device setting request. It is determined whether the setting request from the central device is an individual setting request (step S281), and if it is an individual setting request, the setting value is transmitted to the corresponding device (step S282). If it is not an individual setting request, it is determined whether it is a model-specific setting request (step S283), and if it is not a model-specific setting request, it is determined that it is a request for batch setting of all devices, and the next operation is performed. I do.

【0083】

Set the value of the device counter to 1 (step S284), send the set value to the device with the number indicated by the device counter (step S285), and increase the value of the device counter by one (step S286). Then, the value of the device counter is compared with the number of devices (step S287), the transmission of the set value is repeated until the value of the device counter reaches the number of devices, and when the number of devices is reached, the process returns to step S200.

【0084】

If it is determined in step S283 that the request is for setting by model, the value of the device counter is set to 1 (step S288), and it is determined whether the device with the number indicated by the device counter is the model related to the request. (Step S289), if so, send the set value to the relevant device (step S290). After transmitting the set value, or if it is determined in step S289 that the model is not the model requested, increase the value of the device counter by one (step S291) and compare the value of the device counter with the number of devices (step S291). In step S292), the set value is repeatedly transmitted to the corresponding model until the value of the device counter reaches the number of devices, and when the number of devices is reached, the process returns to step S200.

【0086】

44 and 45 are flowcharts showing an operation procedure in the dryer of the remote management system according to the present invention. The dryer microcomputer reads the value set by the DIP switch and stores it (step S400). Then, it is determined whether or not there is a data transmission request from the DTC (step S401), and if there is no request, the dryer operation is controlled and the data captured from each sensor is processed (step S402), and the process returns to step S401.

【0087】

On the other hand, when a data transmission request from DTC is received, it is determined whether or not its own address is included in the command related to the request (step S403). If the command includes its own address, is the command a trouble monitor request (step S404), a remaining operation time request (step S406), a sales amount request (step S408), or a device setting value request (step S408)? Judging step S410), in response to the trouble monitor request, the presence / absence of troubles such as equipment abnormality and theft, transmission of each data during / stopped operation (step S405), and in response to the remaining operation time request.
