In other instances, detailed descriptions of well-known systems, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
FIG. 1 is a flow chart of a method for maintaining an industrial device according to an embodiment of the present invention;
as shown in fig. 1, a method for maintaining an industrial device includes the following steps:
step S01: tracking and monitoring the running time of the industrial equipment, and sending maintenance reminding information to a specified client when the running time reaches a maintenance time node;
step S02: if the overhaul information fed back by the specified client is received within a preset reminding time period, updating the maintenance information of the industrial equipment, otherwise, sending the maintenance reminding information to the specified client again, and executing the step S03;
step S03: continuing to track and monitor the running time of the industrial equipment, updating the maintenance information of the industrial equipment if the overhaul information fed back by the specified client is received in the next preset reminding time period, and otherwise, executing the step S04;
step S04: and when the industrial equipment stops running, starting a protection mechanism to limit the starting of the industrial equipment.
Specifically, in the above embodiment, the time may be counted from the last time of the completion of the maintenance to the maintenance time node, for example, the time may be counted from the last time of the completion of the maintenance to the 30 th day, that is, the maintenance time node is reached, and a warning mechanism is entered;
specifically, in the reminding and early warning mechanism, a first preset reminding time period is set, timing can be started when a maintenance time node arrives, for example, the first preset reminding time period is 6 days, when the overhaul information fed back by the specified client is received within 6 days, the maintenance information of the industrial equipment is updated, otherwise, the maintenance reminding information is sent to the specified client again; if the overhauled information fed back by the specified client is not received within the first preset reminding time period (namely 6 days), entering the next preset reminding time period;
it should be understood that the next preset reminding time period may be specified as the same time period, that is, within 6 days, or may be different, and in this embodiment, specifically, the next preset reminding time period is set as 4 days, and when the overhauled information fed back by the specified client is received within 4 days, the maintenance information of the industrial equipment is updated, otherwise, the maintenance reminding information is sent to the specified client again;
it should be further understood that the preset reminding time period is set twice, and specifically, the number of times of reminding in the reminding early warning mechanism can be set according to actual situations, for example, the first reminding time period is 6 days, the second reminding time period is 4 days, the third reminding time period is 2 days, and the 4 th reminding time period is that maintenance reminding information is sent every day until the overhaul information fed back by the specified client is received.
In the above embodiment, the industrial equipment maintenance reminding process can be entered according to the set maintenance time node, after several times of reminding, the fed-back overhauled information is still not received, then the protection mechanism is started to limit the opening of the industrial equipment, the industrial equipment which is not overhauled regularly can be effectively prevented from being opened randomly, so that the use of the industrial equipment is limited, and the occurrence of production accidents caused by putting the overhauled industrial equipment into production is greatly avoided.
FIG. 2 is a flow chart of a method for maintaining industrial equipment according to another embodiment of the present invention;
on the basis of the embodiment of fig. 1, the embodiment specifically introduces the protection mechanism, as shown in fig. 2,
step S01: tracking and monitoring the running time of the industrial equipment, and sending maintenance reminding information to a specified client when the running time reaches a maintenance time node;
step S02: if the overhaul information fed back by the specified client is received within a preset reminding time period, updating the maintenance information of the industrial equipment, otherwise, sending the maintenance reminding information to the specified client again, and executing the step S03;
step S03: continuing to track and monitor the running time of the industrial equipment, updating the maintenance information of the industrial equipment if the overhaul information fed back by the specified client is received in the next preset reminding time period, and otherwise, executing the step S04;
step S04: when the industrial equipment stops running, starting a protection mechanism to limit the starting of the industrial equipment:
step S041: calculating the time difference between the stop time of the industrial equipment and the last maintenance information updating time of the industrial equipment;
in this step, for example, the stop time is 7 months and 5 days, and the last time of obtaining the maintenance information update time is 5 months and 15 days, the time difference value between the two is 50 days;
step S042: determining a response grade corresponding to the time difference value according to a preset protection mechanism response grade table;
in this step, a protection mechanism response level table is required to be preset, where the protection mechanism response level table includes each time difference value and a response level corresponding thereto, for example, the time difference value is 40-45 days, and corresponds to a response level 1; the time difference is 46-51 days, corresponding to the response level 2; the time difference is 52-57 days, corresponding to the response grade level 3; the time difference value is more than 58 days, and corresponds to a response level 4;
step S043: generating n corresponding random verification codes according to the level n of the response level, and sending the generated n random verification codes to the switch equipment arranged on the industrial equipment so that the switch equipment can start the industrial equipment through the n random verification codes when the industrial equipment needs to be started;
in this step, for example, if the calculated time difference is 50 days, the query protection mechanism response level table may determine that the corresponding response level is 2, and then 2 random verification codes are generated.
In the above embodiment, the response level is correspondingly started according to the length of the maintenance time interval so as to limit the starting of the industrial equipment, and different levels of response correspond to different numbers of managers to start the equipment together, that is, the higher the response level is, the more the number of manager clients which need to start the equipment is, so that the effect of restraining force is achieved.
The following introduces step S043, which specifically includes:
acquiring an equipment code from the maintenance information of the industrial equipment, and sending the generated n random verification codes to the switching equipment arranged on the corresponding industrial equipment according to the equipment code for pre-storing;
determining whether confirmation information fed back by the switch equipment of the corresponding industrial equipment is received or not within a preset time period, and if the confirmation information is not received, retransmitting the n random verification codes to the switch equipment;
if n is less than 2, when a request starting instruction sent by a first client is received, carrying out identity verification on the first client, and if the verification is successful, sending the random verification code to the first client so that the switching equipment can be checked by the pre-stored random verification code and the random verification code sent by the first client to start the industrial equipment when the industrial equipment needs to be started;
if n is more than or equal to 2, the n random verification codes are n different random verification codes, when a request starting instruction sent by a second client is received, the second client is subjected to identity verification, and if the verification is successful, one random verification code in the n random verification codes is sent to the second client; when a request starting instruction sent by a third client is received, carrying out identity verification on the third client, if the verification is successful, sending one random verification code in the remaining random verification codes to the third client until n random verification codes are correspondingly sent to n clients which verify successfully, so that the switching equipment is checked through n pre-stored random verification codes and n random verification codes sent by the n clients when the industrial equipment needs to be started, and starting the industrial equipment if the n random verification codes are checked successfully;
for example, if the calculated time difference is 53 days, the query protection mechanism response level table may determine that the corresponding response level is 3, and then 3 different random verification codes are generated, so that 3 specified clients are required to jointly turn on the switching device on the industrial device; it should be understood that each client has a unique ID identification, verifies whether ID101, i.e., the client verifying ID101 is previously set as an administrator client when the client numbered as ID101 transmits a "request for opening instruction", transmits 1 random authentication code of 3 different random authentication codes to the ID101 client if the verification is successful, verifies ID103 when the client numbered as ID103 transmits a "request for opening instruction", transmits 1 random authentication code of the remaining 2 random authentication codes to the ID103 client if the verification is successful, verifies ID108 when the client numbered as ID108 transmits a "request for opening instruction", transmits the last 1 random authentication code to the ID108 client if the verification is successful, and then, when the industrial apparatus is turned on, the switching apparatus checks by the 3 random authentication codes prestored and the 3 random authentication codes transmitted by the clients numbered as ID101, ID103, and ID108, and starting the industrial equipment if the verification is successful.
Specifically, in the above embodiment, a switch device is additionally installed on the industrial device, the switch device can start the industrial device only by verifying a random verification code, and the random verification code is sent to a client specified after verification succeeds, that is, when a protection mechanism is started, the industrial device cannot be started by any person, and must be started by a person in charge or a manager, that is, a user of the specified client, so that whether the industrial device is started or not is determined by the person in charge or the manager, thereby avoiding the risk that the industrial device which is not overhauled is started to operate at will, and greatly avoiding the occurrence of safety accidents.
In the above embodiment, to ensure safety, when the industrial device stops operating this time, that is, when the industrial device completes the work this time, the protection mechanism is started to generate the random verification code information.

step S01: tracking and monitoring the running time of the industrial equipment, and sending maintenance reminding information to a specified client when the running time reaches a maintenance time node;
step S02: if the overhaul information fed back by the specified client is received within a preset reminding time period, updating the maintenance information of the industrial equipment, otherwise, sending the maintenance reminding information to the specified client again, and executing the step S03;
step S03: continuing to track and monitor the running time of the industrial equipment, updating the maintenance information of the industrial equipment if the overhaul information fed back by the specified client is received in the next preset reminding time period, and otherwise, executing the step S04;
step S04: when the industrial equipment stops running, starting a protection mechanism to limit the starting of the industrial equipment:
step S041: calculating the time difference between the stop time of the industrial equipment and the last maintenance information updating time of the industrial equipment;
step S042: determining a response grade corresponding to the time difference value according to a preset protection mechanism response grade table;
step S043: generating n corresponding random verification codes according to the level n of the response level, and sending the generated n random verification codes to the switch equipment arranged on the industrial equipment so that the switch equipment can start the industrial equipment through the n random verification codes when the industrial equipment needs to be started;
the protection mechanism further comprises the steps of:
step S044: and when the overhauled information fed back by the client is received, canceling the protection mechanism, and updating the maintenance information of the industrial equipment.
In the above embodiment, if the maintenance of the industrial equipment is completed, that is, when the overhaul information fed back by the client is received, the protection mechanism is closed, and the industrial equipment can be normally used without limiting personnel to open the equipment. On the other hand, the switchgear is low in installation cost, good in effect and beneficial to popularization and implementation.
Specifically, in the several embodiments described above, the maintenance information includes: run time, equipment overhaul parameters, maintenance time, and maintainer information.
