During the cooling process of the concrete, the maximum temperature control is required, that is, the maximum temperature that different pouring bins should reach after the concrete is poured; The properties, labels, different partitions, time periods and early water supply of hot and low-heat concrete are related to the morning and evening.

The purpose of controlling the maximum temperature of concrete is to avoid excessive temperature stress of mass concrete or concrete cracking due to the temperature difference between the foundation, the upper and lower layers, and the temperature difference between the inside and outside. The following factors are mainly considered in determining the maximum temperature of dam concrete construction:

①In order to control the basic temperature difference stress, the maximum temperature should not exceed the sum of the joint grouting temperature and the allowable temperature difference; ②In order to control the internal and external temperature difference stress, the maximum temperature should not exceed the maximum temperature determined by the internal and external temperature difference; ③The maximum temperature limit should be based on the constraint area It should be distinguished from the strength of the constraint of the unconstrained area of the concrete.

In a preferred embodiment, the data acquisition cabinet adopts the gradient closed-loop control learning method, as follows, as shown in Figure 3:

The gradient closed-loop intelligent control learning method utilizes a traditional PID controller and a deep learning-based controller. Traditional PID controllers require a lot of time and energy to adjust parameters. Combined with deep learning network technology, parameter adjustment can be greatly optimized.

(1) Proportional link: Instantly respond proportionally to the flow deviation signal of the control system: K _p e(t). In an analog G(s) controller for flow, the proportional link reacts instantaneously to flow deviations. The proportional coefficient K _p must be properly selected, so that the transition time is short, the static difference is small and stable technical effects can be achieved. In actual flow control, this ratio can be determined based on experience. Intelligent learning of concrete water supply characteristics in different seasons and cooling water stations.

只要存在偏差，它的控制作用就不断的增加，特别是控制的参数增加到一定量后，系统循环响应的量会导致系统运行负荷增加，必须根据实际不同智能控温阶段的具体要求来确定积分常数TI,。(2) Integral link: It is mainly used to eliminate static errors and improve the indifference of the system. The strength of the integral action depends on the integral time constant TI. The larger the TI, the larger the time interval for adjusting the flow, the weaker the integral action, and vice versa. The mathematical expression of the integral link is:

As long as there is a deviation, its control function will continue to increase, especially when the controlled parameters increase to a certain amount, the amount of system cyclic response will lead to an increase in the system operating load, and the integral must be determined according to the specific requirements of different stages of intelligent temperature control. The constant TI,.

偏差变化的越快，微分控制器的输出就越大，在偏差值变大之前进行修正。微分作用的引入，将有助于减小超调量，克服振荡，间接使温度控制系统趋于稳定，微分环节的作用由微分时间常数TD决定。TD越大时，则它抑制偏差e(t)变化的作用越强；TD越小时，则它反抗偏差e(t)变化的作用越弱。(3) Differential link: Differential link:

The faster the deviation changes, the greater the output of the differential controller, and the correction is made before the deviation becomes larger. The introduction of the differential action will help reduce the overshoot, overcome the oscillation, and indirectly stabilize the temperature control system. The action of the differential link is determined by the differential time constant TD. The larger the TD, the stronger the effect of suppressing the change of the deviation e(t); the smaller the TD, the weaker the effect of resisting the change of the deviation e(t).

(4) Deep learning link: According to the on-site working conditions and the accumulated experience of long-term intelligent temperature control work, the deep reinforcement learning-DRL method is used to construct the above controller. The specific implementation steps of the following method are as follows:

S1: Training set, collect temperature control information of mass concrete in past real scenes, including temperature control data of hydraulic dam, measured concrete temperature, water pipe pressure, flow rate, air temperature and water temperature, etc.

S2: Establish a DQN network, determine the reward and punishment value Reward and state state transition information, determine the action space of the strategy (flow of water pipes), and the value parameters of all water pipes corresponding to actions, and determine the best action according to the above metric values.

S3: Use the training set to train and learn the simulation model to obtain a typical data set.

S4: Use the above trained model to perform real-time traffic adjustment.
