Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0025] Figure 1 It is a schematic diagram of the system structure connection of the present invention. DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Reference Figure 1 As shown, the present invention provides a safety verification system for an industrial controller, comprising: an in-furnace parameter setting module, an out-furnace equipment monitoring module and a safety assessment control module.

[0028] It should be noted that the furnace parameter setting module is connected to the database, the external furnace equipment monitoring module is connected to the database, the safety assessment control module is connected to the database, the furnace parameter setting module is connected to the external furnace equipment monitoring module, and the external furnace equipment monitoring module is connected to the safety assessment control module.

[0029] It should also be noted that the database is used to store the reference liquid level of the equipment inside the furnace of the steel industry controller, the reference fuel flow and reference air flow of the equipment inside the furnace of the steel industry controller, the reference weighing of the furnace charge of the equipment outside the furnace of the steel industry controller in each area, the reference value of the furnace mouth cooling of the equipment outside the furnace of the steel industry controller in each area, the reference oxygen concentration outside the furnace and the reference content of harmful gases of the equipment outside the furnace of the steel industry controller in each area, the operating safety compliance index range of the equipment inside the furnace of the steel industry controller, and the operating safety compliance index range of the equipment outside the furnace of the steel industry controller.

[0031] It should be noted that the liquid level of the furnace equipment of the steel industry controller needs to be maintained at an appropriate level at each time period during the heating process to ensure that the fuel and air can be fully mixed and achieve the ideal combustion effect. If the liquid level is too low, it may cause incomplete combustion and affect the heating efficiency of the furnace equipment. If the liquid level is too high, it may cause the fuel controlled by the furnace equipment to overflow or produce too much smoke.

[0032] It should be noted that if the fuel flow and air flow of the furnace equipment of the steel industry controller are too sufficient in each time period during production, it will lead to incomplete combustion, reduce thermal efficiency, and may cause safety hazards. On the contrary, if there is too much air and insufficient fuel, although the generation of harmful gases can be reduced, it will reduce the temperature of the equipment in the furnace, prolong the heating time of the equipment in the furnace, and affect production efficiency.

[0033] In the above embodiment, the analysis of the operation safety compliance index of the furnace equipment of the steel industry controller is specifically performed by detecting the liquid level, fuel flow rate and air flow rate of the furnace equipment of the steel industry controller in each time period during production by a liquid level detector and a flow meter, analyzing the combustion quality compliance index Q of the furnace equipment of the steel industry controller and the combustion safety index W of the furnace equipment of the steel industry controller, and then analyzing the operation safety compliance index of the furnace equipment of the steel industry controller.

If the charge weighing is inaccurate, it may lead to incomplete reaction in the furnace or excessive by-products, thus affecting the regulation of the equipment in the furnace.

[0039] It should be noted that the control of the furnace mouth cooling value is very important to prevent overheating and protect the furnace mouth equipment. If the cooling is insufficient, it may cause the furnace mouth equipment to overheat, shorten the equipment life, and even cause safety accidents.

[0040] It should also be noted that the control of oxygen concentration and harmful gas content outside the furnace by external equipment is crucial to ensuring the safety of the working environment. Appropriate oxygen concentration can prevent the formation of oxygen-deficient or oxygen-rich environment and avoid threats to the health of workers.
