DETAILED DESCRIPTION

[0017] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0018] See attached Figure 1-8 As shown, a centralized control and management system for heat treatment of thick steel plates includes a centralized control center, an operation group and a workshop unit group; the workshop unit group is connected to the centralized control center signal through a switch, and the operation group is connected to the centralized control center signal through a switch.

[0019] The operation group includes an operation position that can control the workshop unit group through the centralized control center, and there are multiple operation positions, each of which is equipped with a staff member, and there are preferably three operation positions. The staff can monitor and manage the workshops in the workshop unit through the centralized control center.

[0020] The centralized control center includes a primary system HMI module, a secondary system HMI module, an out-of-limit parameter unit, a storage module capable of recording and saving information, a status module capable of detecting the status of workshop equipment, a signal communication module capable of sending and receiving signals, a control module capable of sending control signals to workshop units, and a display panel capable of displaying operations. The out-of-limit parameter unit includes a furnace temperature unit, a process unit, and a straightening roller gap unit; the workshop unit group includes a shot blasting machine unit, a heat treatment furnace unit, a cooling bed and transverse table unit, a straightening unit, a grinding table unit, and an exit roller table unit. There are two shot blasting units, and each unit in the workshop unit group includes a camera capable of observing the on-site conditions.

[0021] Through the display panel in the centralized control center, the staff can control and manage each unit in the workshop unit group through the primary system HMI module and the secondary system HMI module, and cooperate with the status module and the over-limit parameter unit to enable the staff to view the information of the working equipment. For example, when the furnace temperature of the heat treatment furnace is too high, the status module can collect the temperature and compare it with the preset high temperature limit in the over-limit parameter unit. When it exceeds the limit, the over-limit parameter unit sends a signal. After the display panel sends a prompt, the staff sends it to the alarm module inside the corresponding workshop unit through the display panel through the control module and the primary and secondary system modules and the communication module to issue an alarm to remind nearby staff to check. At the same time, the control module inside the corresponding workshop can be remotely controlled through the control module in the centralized control center to operate the corresponding equipment.

[0022] The display panel also includes an emergency stop button, an operation button, a joystick and a large monitoring screen. The settings of the emergency stop button, the operation button, the joystick and the large monitoring screen enable the display panel to have certain operating functions, so that the staff can perform quick emergency operations without arriving at the corresponding workshop.

[0023] Furthermore, the shot blasting unit also includes a shot blasting controller capable of sending and receiving signals, a shot blasting laser ranging module for measuring the thickness of the steel plate, a shot blasting image acquisition module for acquiring image information of the steel plate, a shot blasting control panel capable of locally controlling the shot blasting machine, a shot blasting alarm module for issuing a fault alarm, a shot blasting signal module capable of sending and receiving signals, and a shot blasting machine.

[0024] The controller in the shot blasting unit can send the information of the shot blasting laser ranging module and the shot blasting image acquisition module in the shot blasting unit to the centralized control center for processing. Afterwards, the staff can directly observe the working status of the shot blasting machine according to the display panel. When the working parameters of the shot blasting machine are abnormal, the staff can directly adjust the working parameters of the shot blasting machine through the shot blasting controller. For example, when there is a small problem with the conveying offset, the staff can also issue instructions through the centralized control center to perform remote control adjustments. There is no need for the staff to manage on-site all the time, which saves manpower. When the problem cannot be solved by adjustment, an alarm can be issued through the shot blasting alarm module.

[0025] Furthermore, the heat treatment furnace unit also includes a heat treatment furnace controller, a heat treatment furnace temperature detection module, a heat treatment furnace image acquisition module, a heat treatment furnace alarm module, a heat treatment furnace control panel, a heat treatment furnace communication module and a heat treatment furnace.

[0026] The heat treatment furnace controller can send the information collected by the heat treatment furnace temperature detection module of the heat treatment furnace unit and the images collected by the heat treatment furnace image acquisition module to the centralized control center for processing. Afterwards, the staff can directly observe the working status of the heat treatment furnace according to the display panel for real-time monitoring. When the working parameters of the heat treatment furnace are abnormal, the heat treatment furnace controller can also be used to control the work of the heat treatment furnace. For example, when the processing temperature is high or low, it can be adjusted through remote control. There is no need for staff to manage on-site all the time, which saves manpower. When the problem cannot be solved by adjustment, an alarm can be issued through the alarm module to remind nearby staff to come for emergency processing.

[0027] Furthermore, the cooling bed unit also includes a cooling bed controller, a cooling bed over-limit detection module, a cooling bed image acquisition module, a cooling bed alarm module, a cooling bed control panel, a cooling bed communication module, and a cooling bed and a transverse moving stage. The cooling bed over-limit detection module, the cooling bed image acquisition module, the cooling bed alarm module, the cooling bed control panel, the cooling bed communication module, and the cooling bed and the transverse moving stage are all connected to the cooling bed controller by signals through wires, and the cooling bed controller is connected to the signal communication module by signals through a switch.

[0028] When the cooling bed in the cooling bed unit effectively cools the product, if the temperature of the cooled product is greater than or less than the specified range, the cooling bed over-limit detection module will detect it and immediately send the abnormal data to the centralized control center through the cooling bed controller. After receiving the information, the centralized control center will display it on the display panel for the staff at the operating position to observe and adjust the equipment in the cooling bed unit through the centralized control center. If the problem cannot be solved by adjustment alone, the cooling bed alarm module can also sound an alarm to remind nearby staff to come for emergency processing.

[0029] Furthermore, the straightening unit includes a straightening controller, a straightening over-limit detection module, a straightening image acquisition module, a straightening control panel, a plate number recognition module, a straightening alarm module, a straightening communication module and a straightening machine.

[0030] When the steel plate in the straightening machine is offset, the straightening image acquisition module will capture the picture in real time, which is convenient for the staff to observe in real time. At the same time, in conjunction with the straightening over-limit detection module, when the steel plate offset angle is too large and cannot be straightened automatically, the straightening over-limit detection module will cooperate with the alarm module to sound an alarm to remind the staff.

[0031] The plate number recognition module includes at least one high-definition camera installed on the straightener, which can identify the model of the steel plate on the straightener. The plate number recognition module takes pictures with the high-definition camera to obtain the steel plate character picture, and accurately recognizes the steel plate number through the image character recognition (OCR) model algorithm. The plate number consists of Arabic numerals and English letters. The designed character recognition algorithm module can recognize the following characters: (1) Arabic numerals “0, 1, 2, 3, 4, 5, 6, 7, 8, 9”; (2) “A, B, C, D, E, F, C, H, I, J, K, L, M, N, O, P, 0, R, S, T, U, V, W, X, Y, Z” the twenty-six English letters.

[0033] By setting up the grinding table over-limit detection module in the grinding table unit, it can be used to detect whether the steel plate on the grinding table is offset during the transportation process and whether the grinding device is operating normally. When the offset angle does not meet the requirements of the over-limit detection module, the grinding table over-limit detection module will perform detection and send a signal to the operation position in the control center through the grinding table controller so that the staff at the operation position can perform remote control.

[0035] By setting up the exit roller image acquisition module in the exit roller unit to detect the position status of the steel plate at export, when the steel plate rubs against the side of the roller, the signal can be sent to the control center through the exit roller controller in time, and then the staff at the operating position can be reminded to make remote adjustments through the display panel.

[0036] The signals sent by all controllers in the workshop unit group are received by the communication module of the centralized control center and analyzed by the primary system module and the secondary system module.

[0037] The shot blasting control panel, heat treatment furnace control panel, cooling bed control panel, straightening control panel, grinding table control panel and exit roller table control panel are designed so that when a problem occurs in the corresponding workshop unit, the staff can perform local operations through the control panel of the corresponding workshop unit according to the actual environment, without the need for remote operation from the centralized control center.

When the steel plate arrives at the heat treatment furnace in the heat treatment unit, the temperature detection module of the heat treatment furnace detects the temperature in the furnace and sends the information to the centralized control center in real time through the heat treatment furnace controller. When an equipment abnormality occurs, causing the temperature to be too high or too low, the storage module records it and the alarm module of the heat treatment furnace sends out an alarm, which allows the staff at the operating position to remotely control the heat treatment furnace through the heat treatment furnace controller to adjust the equipment temperature.

The status module of the centralized control center analyzes it. The staff can send control information to the export roller controller through the display panel based on the analysis results, thereby controlling the start, stop and adjustment of the export roller.
