[0046] All terms (including technical terms or scientific terms) used in the present disclosure have the same meanings as those understood by ordinary technicians in the field to which the present disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0047] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0048] At present, in the batch production mode of silk thread making, its control system generally lacks the function of automatically judging whether the materials entering and leaving the storage cabinets, flavors and sugar materials are correct. It simply relies on manually marking the batch, brand, in and out information of the storage cabinet tobacco materials, and marking the brand of the sugar material tank for verification and judgment. The manual verification method is: before the storage cabinet and sugar material tank are in and out of the material operation, the central control operator and the on-site operator communicate and confirm through the intercom. If the verification is correct, the material can be passed. If there is an error, the operation will be stopped and the verification will continue. The manual verification method has the following disadvantages: when the workshop equipment is running, the intercom signal is easily interfered, the noise is large, the clarity is low, the reliability of effective communication is poor, and the timeliness is poor; the number of daily verifications is hundreds or thousands, the labor intensity and work pressure of the operators are high, and negligence and misoperation are prone to occur, affecting the batch production time, and even serious quality accidents.

[0049] like Figure 1 and Figure 2 As shown, the silk thread error prevention system provided in this embodiment includes: an error prevention module 1, an on-site confirmation module 3 and an information display module 2 which are arranged in sequence, wherein:

[0050] The error prevention module 1 is used to obtain the production scheduling plan and work order information, and generate trigger information when the central control terminal selects a storage cabinet or a material tank, and the trigger information is used to indicate the operation information of the central control terminal;

[0051] The on-site confirmation module 3 is used to compare the trigger information with the production scheduling plan at the on-site end according to the work order information to obtain confirmation information;

[0052] The error prevention module 1 is also used to read the confirmation information;

[0053] The information display module 2 is used to display the confirmation information.

[0054] Specifically, the error prevention module 1 includes a factory MES production scheduling unit, an MES database, a field MES terminal and a central control MES terminal, wherein:

[0059] The silk-making workshop production management system database is used to store the work order information.

[0060] The on-site MES terminal is also used to execute the production task according to the work order information.

[0061] Among them, the work order information includes at least one of process parameters, cabinet entry number, cabinet exit number, flavor and / or sugar entry number, tank exit number, brand, and production batch. It should be noted that the present invention does not specifically limit the specific content of the work order information.

[0062] Furthermore, the factory MES production scheduling unit can generate a production scheduling plan, and send it to the on-site operators and central control operators in the workshop through the on-site MES terminal and the central control MES terminal. They can obtain the production scheduling plan respectively. Whether they directly view the MES system or view the printed scheduling list, the scheduling information comes from the MES database. In one embodiment of the present invention, at the central control MES terminal, the central control operator generates a work order through the workshop production management system based on the MES scheduling list. When the central control worker selects a storage cabinet or a material tank, the corresponding information is triggered, and this information is transmitted to the on-site confirmation module 3 of the on-site operator. The on-site operator checks this information with the scheduling list of the on-site MES terminal, and confirms that it is correct in the on-site storage cabinet or the fragrant sugar material tank, and then confirms it on the on-site confirmation module 3. This method is not forcibly interlocked with the batches of the storage cabinet and the fragrant sugar material tank. The present invention can realize the error-proof function of the silk thread line entering and exiting the cabinet, and the essence and sugar material entering and exiting the tank.

[0065] In the specific implementation, when a batch is about to start production, at the central control MES terminal, after the central control operator issues a production task, the Wincc monitoring unit reads the work order information from the silk-making workshop production management system database, and then after executing the production task according to the work order information, the Wincc monitoring unit transmits the work order to the underlying PLC control unit, but the information of entering and exiting the cabinet and entering and exiting the tank is not involved in the transmission. The present invention is based on application layer software error prevention, is independent of the dependence on the bottom PLC or Wincc of the workshop, and also regards the system failure (PLC failure or Wincc failure) inside the workshop as part of error prevention.

[0066] Furthermore, the Wincc monitoring unit includes a Wincc control panel,

[0067] The central control MES terminal is also used to select an in-cabinet number or an out-cabinet number on the Wincc control panel to start the equipment for production, and at the same time, generate trigger information, which is used to indicate the operation information of the central control MES terminal;

[0068] The silk-making workshop production management system database is also used to store the trigger information;

[0069] In the specific implementation, at the central control MES terminal, the central control operator selects the combination of the cabinet entry number and the cabinet exit number on the Wincc control panel and starts the equipment for production. When selecting the cabinet entry number or the cabinet exit number, a trigger information will be generated. This trigger information is stored in the silk workshop production management system database.

[0070] Furthermore, the silk-making workshop production management system database is also used to store the confirmation information of the on-site confirmation module 3;

[0071] The Wincc monitoring unit is also used to read the confirmation information;

[0072] The Wincc monitoring unit is also used to send an early warning message to the central control terminal when the on-site confirmation module 3 fails to confirm.

[0073] In the specific implementation, the Wincc monitoring unit reads the confirmation information. If the confirmation is passed, the information display system database obtains the work order information, such as batch number, brand number, etc., from the silk-making workshop production management system database, and transmits this information to the information display module 2; if the confirmation is not passed, the Wincc monitoring unit will send an early warning message to the central control MES terminal to inform the central control operator. After receiving the early warning message, the central control operator will re-verify and re-operate until the confirmation is passed.

[0074] Furthermore, the signal source of the error prevention module 1 includes a Wincc script signal, and the data interface of the error prevention module is a Web Service. In one embodiment of the present invention, the control can be configured in Wincc.

[0075] Furthermore, the on-site confirmation module 3 includes a mobile tablet or a smart phone, and the movable confirmation device is convenient for on-site personnel to carry to the material site for verification, as a new error-proofing system confirmation method. The data transmission of the on-site confirmation module 3 adopts a wireless transmission method. In a specific implementation, the on-site operator can read the trigger information from the silk-making workshop production management system database through a mobile terminal such as a mobile tablet or a smart phone. The on-site operator can obtain the operation information (including in or out cabinet operations, storage cabinet number, etc.) performed by the central control operator at the central control MES terminal through the trigger information, and then the on-site operator compares it with the scheduling information previously obtained from the on-site MES terminal, and checks the equipment status on site at the same time. If the information is consistent and the equipment status is normal, it is confirmed to pass. If the information is inconsistent or the equipment status is abnormal, it is confirmed to fail. The confirmation information is stored in the silk-making workshop production management system database.

[0076] Furthermore, the data transmission of the information display module 2 adopts a wired transmission mode.
