Abstract

PURPOSE:To ensure transit of equipment to a guard system and release and also to prevent waste power supply by information start and end of a prolonged running also to a prescribed destination. CONSTITUTION:When a release switch in a designation switch 8 is turned off, the presence of a new fault of equipment is discriminated based on an equipment state signal. When no new fault exists, the propriety of a characteristic value from a sensor is checked directly. When the characteristic value is within the permissible range, the presence of generation of new fault is discriminated immediately. When the fault is a new fault, the content of a fault memory is transmitted to an informing means 6 so as to start the informing operation. When no fault exists, the presence of a prolonged running start flag is checked, and when the flag exists, the prolonged running start is outputted to the informing means 6 so as to start the informing operation. When no flag exists, the presence of the prolonged running end flag is checked immediately, and if the flag exists, the end of prolonged running is outputted to the informing means so as to start the informing operation.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a monitoring and control device for factory equipment and the like having an automatic operation function.

[Prior Art] In recent years, there has been a strong desire for industrial rationalization, and the automation of various types of equipment is rapidly progressing. Because these facilities have automatic driving functions, they can operate not only during normal daytime operation, but also when unmanned, such as at night.
g! Continuous nighttime operation in which unmanned operation continues, extended operation in which operation continues after unmanned operation until certain conditions are met,
Before normal operation, a warm-up run-in or the like is performed as necessary to ensure that predetermined operating conditions are met.

However, even with such unmanned operation, there are problems such as the need to replenish raw materials when there is a limit to the storage capacity of the raw material supply section, and the need to respond appropriately when emergency measures are required for abnormalities. There are many problems such as the problem of not having enough equipment, and the problem of not being willing to stop the equipment.
1S1 It was difficult to operate completely unmanned.

Therefore, a device as shown in Fig. 1 has been proposed that attempts to solve the above problem by notifying a predetermined tracking light only when human processing or measures are required during unmanned operation. . The reporting device (1) according to this proposal is activated upon receiving an abnormality signal from, for example, equipment (2), and transmits the contents corresponding to the abnormal signal to a preset reporting destination (4) via a line (3). ).

However, such reporting devices also had drawbacks. That is, the device merely reports an abnormality, and even though there are other matters that need to be reported, the device does not report those matters, reducing the value of the device. For example, the start and end of extended operation were not reported because they were not abnormal.
This matter is worth reporting because it is related to the transition of the security system, etc. In addition, by notifying the start and end of extended operation, the power supply can be quickly turned on and turned off, so it has the value of reporting.

), if there is none, the process proceeds to the mode setting step (S300), and if there is, it is checked whether the reset key among the designated keys (10) is on or off (S202). When it is on, the memory contents of the data input canister that temporarily stores each digit number from the numeric keypad (8) are erased and the process proceeds to the mode setting step (S300), and when it is off, the memory contents of the data input canister that temporarily stores the numbers from the numeric keypad (8) are erased. On/off is determined (S204). When the numeric keypad (8) is on, the value pressed on the data entry key is memorized and the process proceeds to a mode setting step (S300), and when it is off, it is determined whether the designated key (10) is on or off (S205). When any of the specified keys (10) is on, the data in the data input canister is transferred to the storage area corresponding to the key, and the data in the data input canister is also erased, and the process proceeds to the mode setting step (5300), and when it is off, Proceed to direct mode setting step (S300).

The mode setting operation (S300) will be explained based on FIG. 6(d). First, determine whether the continuous operation designation switch in Sui-Sochi (8) is on or off (5301), and if it is on, set it to continuous operation mode and turn on the monitoring lamp in the lamp (13). (S302) The process proceeds to the above-mentioned step 400, and if it is off, it is determined whether the extended operation designation switch is on or off (s3o3). If the extended operation designation switch is on, set the extended operation start flag, set the extended operation mode, and turn on the monitoring lamp (S3
04) Proceed to two consecutive steps 400, and if it is off, check the end time of the extended operation or the resultant force (S305).

When the end time was reached, the extended operation mode was canceled, the extended operation end flag was set, and the monitoring lamp was turned off (930
B) After that, check whether there is an abnormality (S30?), and if there is an abnormality, store the extended operation abnormality in the abnormality memory (830?).
8) Proceed to step 400; if not, proceed directly to step 400. If it is not the end time, check whether the break-in switch is on or off (S301). Sui・
If Sochi is on, check 1-1 whether it is the start time of the break-in operation (S310), and if not, proceed to step 400, and when the time is reached, it is further determined whether there is an abnormality in the extended operation. 5311), in some cases step 40
0, and if it is 1,%, the break-in mode is set, a break-in start flag is set, and both the monitoring and break-in lamps are turned on, and the process proceeds to step 400 (S312).

When the break-in operation switch is off, it is determined whether the extended operation mode is set (53L3), and if it is set, the process proceeds to step 400, and if it is not set, all operation modes are canceled. (S314) Step 4001
Go forward.

Next, the abnormality detection and notification operation (95GO) performed when any of the operation modes is set will be explained based on FIG. 6(e). Determine whether the release switch in the designated switch (8) is on or off (S501), and if it is on, erase the contents of the abnormal memory (S502),
If it is off, it is determined whether there is a new equipment abnormality based on the equipment status signal (S503).

If a new abnormality has occurred, this fact is stored in the corresponding abnormality memory, and the abnormality lamp in the lamp (13) is lit (S504). If there is no new abnormality, the characteristic value directly from the sensor is accepted (S504). For example, whether the product thickness is within the standard is inspected (S505, 350B). If it is outside the allowable range, it is stored in the response error memory, the error lamp is lit (S
507), if it is within the allowable range, the process immediately proceeds to the step for determining whether a new abnormality has occurred (350B).

If there is a new abnormality, the contents of the abnormality memory are sent to the notification means (6) to start the notification operation (9509) and proceed to the operation control step (SfllQO), and if there is no abnormality, the above-mentioned extended operation start flag (93 ( 14) is set up (S510). If it is set up, the start of extended operation is output to the passbook means (6) to start a notification operation (S511), and then it is set up. If not, it is immediately determined whether the extended operation end flag (see saoe) is set (S512).

If the end flag is set, the end of extended operation is output to the notification means (6) and a notification operation is activated (S513), and the process proceeds to the operation control step (S800). If the end flag is not set, the operation control step (S800) is immediately executed. Proceed to S600).

The operation control operation (S600) will be explained in detail based on FIG. 6(f). It is determined again whether the extended operation end flag is set (Si2O3). Equipment (2)
5eo2), after which it is determined whether or not the break-in operation start flag (see S312) is set (SeO2).

If it is set up, it will send out a signal to turn on the power.5NO
B) After that, when a predetermined period of time has elapsed (S807), a break-in operation start signal is sent and the flag is cleared (9).
80B) Proceed to display operation step (S700).

The display operation ('S?00) will be explained in detail based on FIG. 6(g). Is it possible to determine whether the characteristic value display key is turned on or off by the sensor in the CR7 display content specification key (12)? 01),
If it is on, the characteristic value should be displayed on the CRT (11)57
02) If it is off, check whether the equipment status display key is on or off. 03), if it is on, display the status details, such as an abnormal condition, on the CRT (11) 5704),
If this key is also off, check whether there is data in the data input canister 5705), and if there is, display the data being input on the CRT (11) 870B).
, if not, display the current time on the CRT (11) (
S70? ). In either case, after the display, the process returns to the input signal reading operation step (S100) described above, and thereafter, the series of operations described above is repeated.

Through the above-described operations, a predetermined notification destination is notified at the start and end of the extended operation.
