Description

Technical Field

[0001] The present invention belongs to the technical field of control of a formwork drying device, and in particular relates to a control method of a formwork drying device. Background Art

[0002] Before the mold drying process, the operator of the previous process will push the drying cart with the mold to the drying department to wait for drying. The existing drying method is to dry the mold on the cart directly through a fan, and the following disadvantages will occur in this drying process: 1. The operator of the previous process will place the carts that need to be dried at random, causing the site to be messy; 2. The carts are placed randomly and it is impossible to distinguish which carts arrived first and which carts arrived later, which will cause the molds on the carts that arrived first to not be dried first, resulting in the mold expanding and causing the mold to crack; 3. When the operator is busy, it is easy to ignore the mold that has been dried, and it is also easy to cause the failure to replace the cart in time, resulting in some molds drying in time, and some molds not drying in time or overtime. Therefore, it is urgently necessary to invent a control method for the mold drying device. Summary of the Invention

[0003] The purpose of the present invention is to provide a control method for a formwork drying device, which solves the above-mentioned problems of untimely or overtime drying of formwork, the availability of trolleys, and the inability to achieve first-come-first-served drying due to the clutter on site.

[0004] To solve the above technical problems, the present invention provides a control method for a formwork drying device, comprising a drying device used in the method and a control unit connected to the drying device, the control unit comprising a hardware database, an analyzer, a general DAO, an SQL database, and an execution engine, the hardware database being connected to the general DAO, the SQL database, and the execution engine, respectively, and the analyzer being connected to the general DAO and the SQL database, respectively;

[0005] The hardware database is used to load the SQL statements to be executed read by the general DAO;

[0006] The analyzer is used to execute the query data request issued by the general DAO and perform query analysis on the data in the SQL database;

[0007] The general DAO is used to query the data in the SQL database and insert it into the hardware database after analysis by the analyzer. It can also be used to delete the data in the SQL database and the hardware database.

[0008] The SQL database is used to store preset drying process-related SQL statements;

[0009] The execution engine is used to execute data in the hardware database;

[0010] The control unit is connected to a network relay, which is used to open and close the drying device and to change the indication state of the indicator light;

[0011] The drying device includes a frame, a sliding frame, a cylinder and several follower frames, the frame is provided with several parking spaces for placing trolleys, and a sensor detection device is provided on the frame above each parking space, the sensor detection device is used to detect the parking space, the sensor detection device is connected to the control unit through a signal, the sliding frame is slidably connected to the frame, and one end thereof is connected to the output end of the cylinder, the cylinder is arranged on the frame, and several follower frames are arranged at intervals between the two sliding frames, both ends of the follower frame are penetrated by a pin shaft, the pin shaft is arranged on the two sliding frames through a bearing and a bearing seat, the end of the pin shaft extends out of the bearing seat, and a shift rod is sleeved on the outer side thereof, the shift rod is penetrated in the sliding frame, and its end extends out of the sliding frame, and several fans are provided on the follower frame.

[0012] The specific steps of the method are as follows:

[0013] S1. After receiving the drying instruction, the control unit queries the SQL database through the general DAO and analyzes the query data through the analyzer. After the analysis is the preset drying process related SQL statement, the general DAO inserts the relevant SQL statement into the hardware database;

[0014] S2. When the SQL statements in the hardware database are output to the physical execution tree during the physical optimization phase, the physical execution tree is sent to the execution engine for execution. At the same time, the control unit sends instructions to the network relay. After receiving the instructions, the network relay supplies power to the cylinder in the forward direction, causing the cylinder's output shaft to retract to the shortest stroke.

[0015] S3: The sensor detection device on the rack detects whether there is a vacant parking space. The sensor detection device sends the retrieved parking space data signal to the control unit. The control unit receives the signal that the parking space is vacant and controls the physical execution tree to re-execute. When the control unit retrieves that the parking space is full, the control unit's execution engine sends an instruction to start the drying device to the network relay. The network relay energizes the drying device, and the network relay energizes the cylinder in forward and reverse directions. The output shaft of the cylinder drives the sliding frame to move, and the lever installed in the sliding frame swings accordingly, and the fan also swings accordingly. The fan reciprocates to dry the mold shell on the trolley in the parking space.

[0016] S4. After the drying is completed, the network relay receives the reminder instruction sent by the physical execution tree to the execution engine, and changes the indicator light to yellow. At the same time, the control unit starts the timer for timing;

[0017] S5. The control unit compares the timing data of the timer with the duration data specified in the physical execution tree. If the timer duration reaches the preset duration, the network relay receives a completion instruction sent by the physical execution tree to the execution engine, turns off the drying device, and changes the indicator light to red. If the timer duration exceeds the preset duration, the network relay receives a timeout instruction sent by the physical execution tree to the execution engine, and the network relay changes the indicator light to flashing red.

[0018] S6. After the sensor detection device on the rack detects that the trolley has been removed, it sends a signal to the control unit. After receiving the signal, the control unit deletes the parking space drying information collected in the hardware database through the general DAO. At the same time, after the network relay receives the waiting-to-run instruction sent to the execution engine by the physical execution tree, it turns the indicator light to green and returns to S1 to continue the above steps.

[0019] Furthermore, the execution steps of the method are repeatedly executed within a preset time.

[0020] Furthermore, the cylinder is connected to a solenoid valve, and the network relay is connected to the solenoid valve.

[0021] Beneficial effects of the present invention: The control method of the present invention adopts the universal DAO in the control unit to send a signal to the analyzer, the analyzer queries the SQL database, queries the relevant drying data, composes the relevant SQL statements of the data into an execution tree and sends it to the execution engine for execution. During the control process, the control unit sends an action instruction to the network relay, so that the drying device can realize automatic operation of the mold shell on the trolley, thereby solving the problems of uneven drying of the mold shell, resulting in depression, different internal and external shrinkage forces, expansion and cracking, etc., solving the problem that the operator needs to check the information of the trolley one by one before determining whether the next step can be carried out, solving the problem that the operator randomly selects the nearest trolley for drying during the process, causing the mold shell produced early to be unable to be dried, and solving the problem that the operator forgets to turn off the fan and causes increased power consumption, effectively improving production efficiency and saving production costs;

[0022] The parking space for the trolley is set inside the frame, which effectively solves the problem of operators placing the trolley at will. BRIEF DESCRIPTION OF THE DRAWINGS
