Hereinafter will be described in detail the operation of the automatic steam curing system and management method using the same according to the present invention having the configuration as described above.

Before performing steam curing, the manager executes a curing condition input step of inputting curing conditions through the management device 70. As shown in FIG. 3, the steam curing passes through a temperature pretreatment step (A), a temperature rise step (B), a temperature maintenance step (C), and a temperature decrease step (D). Therefore, the administrator can set the time and temperature for each step in the curing condition input step. However, in the case of the temperature lowering step (D), a natural cooling method is mainly used.

In the curing condition input step, it is possible to input a condition regarding a season in which steam curing is performed. If the administrator enters the summer mode into the management device, the temperature and humidity are high in summer, so the temperature is controlled to be lowered.

In addition, the curing condition input step may be set by limiting the maximum and minimum temperature and the maximum and minimum steam pressure. The manager may secure the stability of the steam generator 15, the valve 16, and the steam injection port 19 by limiting the highest and lowest temperatures and the highest and lowest steam pressures through the management device 70. In this case, the manager may individually control the operations of the steam generator 15 and the valve 16 through the management device 70.

When the curing condition is input by the curing condition input step, the curing preparation step is performed. In the curing preparation step, the management device 70 displays data on the remaining amount of water in the water tank and the remaining oil amount in the oil tank for steam curing. After checking the data through the management device 70, the manager may open valves connected to the water tank and the oil tank to replenish water and oil.

When steam curing is prepared by the curing preparation step, the manager inputs steam curing start through the management device 70. When steam curing is started, the steam generator 15 is operated by the central processing unit 50 and the device operating device 60.

When the steam generator 15 is operated to generate steam, steam is injected into the steam injection port 19 through the steam pipe 17 under the control of the valve 16. Steam curing is performed on the concrete object 10 by the steam injected through the steam injection port 19.

When steam curing is performed on the concrete object 10, a temperature raising step of gradually increasing an internal temperature of the concrete object 10 is first performed. The data measuring device 30 continuously increases the internal temperature of the concrete object 10 by operating the valve 16 according to a temperature and time input by an administrator for the first time.

When the internal temperature of the concrete object 10 reaches a temperature first input by the administrator, a temperature maintenance step is performed. In the temperature maintaining step, the central processing unit 50 controls the operation of the valve 16 so as not to exceed the maximum temperature and steam pressure input by the manager.

In other words, the CPU 50 is controlled to maintain the temperature required for steam curing because the CPU 50 controls the measured value for each unit time to follow the set value for each time in real time by calculating the set value for each time in real time. .

The CPU 50 calculates an average value of temperature data measured on the surface and the inside of the concrete object 11 and humidity data measured by the humidity measuring device 19 for each predetermined time, and then inputs the temperature and humidity input by the administrator. Continue to determine if it is within the scope.

According to the determination result of the CPU 50, the steam generator 15 may be started or stopped through the apparatus operating device 60. The control result of the central processing unit 50 is continuously recorded in the data storage unit 51.

The central processing unit 50 determines that the curing end condition is satisfied when the curing temperature, curing time, etc., which are first input by the manager, is satisfied, and the operation of the steam generator 15 and the valve 16 is stopped. When the operation of the steam generator 15 and the valve 16 is stopped, the concrete object 11 is subjected to a cooling process in a natural state.

Curing-related data is continuously measured and analyzed even while the concrete object 11 is cooled. The CPU 50 controls the set value of the temperature controller to follow the measured value for temperature recording.

If there is a risk of cracking due to insufficient humidity inside the concrete object 11 during the cooling process, the central processing unit 50 performs a water replenishment step.

In the water replenishment step, the water supply device 21 connected to the device operation device 60 is operated to supply water to the concrete object 11. When a predetermined moisture is supplied by the water supply device 21, the concrete object 11 is cooled to a natural dry state again.

When the steam curing is finished in this way, various data and control records measured in the steam curing process are stored in the management device 70. The management device 70 outputs measurement data and control records through the output device 80 under the control of an administrator. The manager may improve the problems in the steam curing process by reviewing the data on the steam curing process output through the output device 80.

In addition, the operation of the valve 16 may be stopped by the input of the manager during the steam curing process, and if a problem occurs in the steam generator 15 and other curing-related equipment may notify the manager through the alarm.

In the scope of the basic technical spirit of the present invention, many modifications are possible to those skilled in the art, and the scope of the present invention should be interpreted based on the claims which will be described later. .

According to the steam curing automatic management system and a management method using the same according to the present invention as described in detail above, the following effects can be obtained.

First, since the central control unit controls the curing-related equipment according to the curing conditions first input by the manager through the management equipment, the manager does not need to directly control the steam curing process, thereby increasing convenience in use.

In addition, since the manager can control the curing process immediately by monitoring the curing process through the management device, there is an advantage that it is possible to immediately respond to the environment change for steam curing and increase the efficiency of steam curing.

In addition, since the data on the steam curing process stored in the management device can be confirmed through the output device, problems derived from the steam curing process can be identified and fed back, thereby improving the effectiveness of steam curing.
