Detailed Description
The invention will be described in further detail with reference to the drawings and the detailed description.
The conventional safety measure execution management method is to find out corresponding paper safety measure execution items after receiving the work ticket, wherein each execution item is arranged, and each execution item is confirmed by each executor, usually in a hooking way. However, some operators can break rules and operate, firstly, hook and then execute, or firstly execute and then hook, and cannot execute one item of confirmation, so that the problems of error or misoperation of an operation object and the like are easy to occur.
Aiming at the defect of the traditional safety measure execution management mode, the safety measure execution closed-loop management system and method for the thermal power plant disclosed by the scheme can realize the electronic confirmation of safety measure execution on the basis of the traditional two-ticket business, and through the implementation of the scheme, an executive can be confirmed only by the associated equipment for correctly executing each safety measure execution item, so that the problems of misoperation and execution omission are avoided. The specific scheme is as follows:
example 1
As shown in fig. 1 and 2, the system comprises an identity module 3, an identity information acquisition module 11, an execution item confirmation module 12, a memory 4 and a control module 2.
In particular, the identification module 3 is located at the respective field device for storing field device identity information.
The identification module 3 of this embodiment is an identification code, such as a two-dimensional code, a bar code, a three-dimensional code, or a small program code, which is attached to each field device. The identification code stores the identity information of the corresponding field device, and when the identification code is scanned, the scanner can acquire the identity information of the corresponding field device. The identification information refers to the code of the corresponding equipment, if one equipment possibly needs to execute a plurality of unassociated safety measures, a plurality of identification codes are preferably pasted on the corresponding equipment, each identification code is respectively pasted at the position where an executor needs to execute corresponding An Cuoxiang, each identification code has different identification information to distinguish An Cuoxiang, if the C1B belt conveyor needs to be executed to stop the C1B belt conveyor and pull the C1B belt conveyor to be powered off, two identification codes are pasted on the C1B belt conveyor, B-C and B-e are respectively stored in the two identification codes, the identification code stored in B-C is pasted at the start-stop switch of the C1B belt conveyor, the identification code stored in B-e is pasted at the power switch of the C1B belt conveyor, and then B is the code representing the C1B belt conveyor. B-C is a code indicating the C1B belt drive start-stop switch (or a code indicating the safety measure of performing the C1B shutdown operation); likewise, B-e represents the code at the C1B belt drive power switch (or code to indicate that the measure of pulling the C1B belt drive power off is being performed). The executor scans the B-e identification code to confirm that the C1B belt conveyor power supply is pulled open when operating the power switch; and when the start-stop switch is operated, the B-C identification code is scanned to confirm that the C1B belt conveyor is stopped.
An unassociated measure refers to one measure being performed, and another measure may or may not be performed. And after one An Cuoxiang of the associated safety measures is executed, the other safety measure is also executed simultaneously, for example, when the C1B belt conveyor and the C18B belt conveyor and the iron remover share the power supply, the power switch of the on-site control box of the C18B belt conveyor and the iron remover are pulled simultaneously when the power supply of the C1B belt conveyor is pulled. For the associated safety measure, the executor only needs to execute one item, the identification code only needs to identify one item, and the associated safety measure can be executed as one item An Cuoxiang.
The identity information acquisition module 11 is configured to acquire field device identity information from the identity module 3. Accordingly, the identity information acquiring module 11 of the present embodiment includes a camera for scanning the identification code. When the method is put into use, an executor scans the identification code before or after executing a field device, and because the execution identification is performed item by item, the execution omission problem cannot be caused even if the executor confirms before executing the security measure, the method preferably recommends the executor to perform the execution after the execution of the identification code, and thus the problem of misoperation on an error object can be avoided.
The execution item confirmation module 12 is used for being operated by a user to send a confirmation request of the corresponding safety measure execution item.
The control module 2 is connected with the memory 4, the execution item confirmation module 12 and the identity information acquisition module 11, and is used for extracting the associated equipment identity information of the corresponding execution item and acquiring the field equipment identity information when receiving the safety measure execution item confirmation request of the execution item confirmation module 12, then comparing the consistency of the field equipment identity information and the associated equipment identity information, giving a confirmation result according to the comparison result, and confirming success when the comparison is consistent, otherwise, confirming failure. Only when the executor arrives at the site equipment, the executor can confirm success, and when the executor arrives at the wrong equipment, the identity information of the site equipment is inconsistent with the identity information of the related equipment, the corresponding safety measure execution item cannot be confirmed, the executor can also know that the equipment in front of the executor is not the equipment to be executed by the executor in time, and the problem of misoperation of the executor can be avoided. And also because the execution can be confirmed only before the field device, the operator cannot operate illegally, i.e. cannot perform all the operations before unhooking or perform all the operations after unhooking, and must perform one confirmation.
Further, the identity information acquiring module 11, the execution item confirmation module 12, the memory 4 and the control module 2 of the present embodiment are all located in the mobile terminal 1, the mobile terminal 1 is connected to the server 5 through a 5G network, a 4G network or a wifi network, the mobile terminal 1 includes a touch display screen, the execution item confirmation module 12 includes an safety measure execution confirmation button located on the touch display screen, and the execution person can perform confirmation of the corresponding safety measure execution item by clicking the safety measure execution confirmation button at the corresponding position on the touch screen.
The server 5 may be an original ERP system server, and introduces a flow of an intrinsic safety measure execution list between a long approval working time of a conventional ERP work ticket flow value and a permission of a work licensor to start a working flow node, as shown in fig. 3, after a conventional work ticket task issuing step (i.e. after the work ticket approves the working time), the steps are further executed: extracting all safety measure execution items corresponding to the current work ticket, dividing all safety measure execution items into a plurality of Zhang Ancuo execution sheets according to the profession, and simultaneously locking the main flow of the work ticket until all safety measure execution items are successfully confirmed. Each safety measure execution list can be directly sent to the mobile terminal 1 of the corresponding professional, or can be sent to the responsible person of the corresponding professional, such as a class terminal, and then the responsible person is distributed to the mobile terminal 1 of the specific executor, the executor can see the safety measure execution list distributed to the executor through logging in the account of the executor, and the executor can carry out the confirmation work of each safety measure execution item under the account of the executor. Each execution form may be assigned to one or several executives, typically one execution form is executed by one executor, and one executor may be responsible for several execution forms.
The server 5 sends the safety measure execution list comprising safety measure executors and safety measure execution items to the mobile terminal 1 of the corresponding executor according to the distribution of the safety measure execution list, wherein the safety measure execution list comprises safety measure executors and safety measure execution items, safety measure execution time and safety measure execution confirmation buttons, the safety measure execution items are arranged in sequence according to the operation sequence, and the user sends a confirmation request of the corresponding safety measure execution items by clicking the safety measure execution confirmation buttons. Wherein the safety measure execution time is automatically filled by the mobile terminal 1 according to the confirmation success time of the corresponding safety measure execution item.
Specifically, the server 5 sends the safety measure execution list to the mobile terminal 1, and simultaneously sends the associated equipment identity information of each safety measure execution item in the safety measure execution list to the mobile terminal 1, and the memory 4 at the mobile terminal 1 stores the associated equipment identity information of each safety measure execution item.
Further, as shown in fig. 4, the safety measure execution list is confirmed by the executor or the responsible person of the corresponding professional, that is, the executor itself or the responsible person of the corresponding professional sends a safety measure execution confirmation request to the server 5, the server detects whether all safety measure execution items corresponding to the current safety measure execution list have been successfully confirmed after receiving the safety measure execution list confirmation request, if yes, the confirmation is successful, the mobile terminal 1 of the executor returns the safety measure execution list completed to the server 5, and the server 5 unlocks the work ticket main flow after all safety measure execution lists under the current work ticket have been successfully confirmed.
Further, according to different ticket types, the priority of different professional safety measure execution orders can be set, and the control of the execution sequence of the safety measure execution orders according to the priority can be performed on the safety measure execution orders of different professions. Specifically, the execution work of the subsequent priority safety measure execution list is started after the confirmation of the preceding priority safety measure execution list is successful, and each safety measure execution item can be confirmed only after the execution work of the corresponding safety measure execution list is started.
By the implementation scheme, the security measure execution single-electron method can realize security measure execution single-electron, execution confirmation mobile, record the executor and execution time of each security measure execution item and realize security measure execution responsibility to the person; in addition, the code scanning verification link is introduced when each item An Cuoxiang is executed, and the execution content can be confirmed and executed only when the field device information returned by the identification code is consistent with the associated device information of the safety measure execution item, so that the safety accident caused by violation can be effectively avoided; in addition, the work ticket and the safety measure execution list are interlocked, and the work ticket flow can be unlocked only after the safety measure execution list is completely executed, so that the starting condition can be effectively prevented from occurring when the safety measure is not executed.
