Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tailing pond diversion and discharge, and particularly relates to an intelligent diversion channel system, method and device for tailing pond discharge. BACKGROUND

[0002] The tailing pond is a dangerous source of mud-rock flow with high potential energy, and once dam break occurs, it will cause serious casualties, property losses and adverse social impacts. In addition, the tailings and flood formed after the tailing pond dam break will cause different degrees of damage to life, property, resources and environment in the surrounding area due to the large amount of heavy metals and toxic and harmful substances. On the one hand, the traditional flood discharge method mainly relies on manual control of gate opening and closing for operation, which requires personnel on duty and a large amount of manpower and material resources. On the other hand, the difference between the target discharge capacity calculated and predicted by the existing intelligent control system and the actual required discharge capacity is large, which is not conducive to saving water resources and is easy to cause great impact on the downstream. Thirdly, some on-duty personnel of the tailing pond have no work qualifications, which is easy to cause adverse consequences, increases the operation cost of the tailing pond, and is not convenient for operation, has a long reaction time and low reliability.

[0005] The prior art three, a valley type tailings pond flood discharge system CN201610472483.4, including a preliminary dam arranged downstream of the tailings pond and a flood control dam arranged upstream of the tailings pond, a backwater pool and a stilling pool for collecting backwater of the tailings pond are arranged downstream of the preliminary dam; a main flood discharge tunnel is arranged between the preliminary dam and the flood control dam; a retaining wall is arranged in the main flood discharge tunnel, which separates the main flood discharge tunnel into a clear water side and a sewage side, the upstream of the clear water side of the main flood discharge tunnel is connected with the flood control dam, and the downstream is connected with the stilling pool in communication, and the sewage side is connected with the backwater pool; although the problem of flood pollution diversion of the valley type tailings pond can be effectively solved, the flood discharge mode is artificially controlled, which wastes a lot of manpower and material resources.

[0006] The prior art one, the prior art two and the prior art three have the problems of wasting a lot of manpower and material resources in personnel on duty, and the difference between the target flood discharge calculated and predicted and the actual required flood discharge is large, which is not conducive to saving water resources and is easy to cause great impact on the downstream, so the present application provides an intelligent diversion channel system, method and device for tailings pond discharge, which can monitor the water level in the tailings pond in real time and continuously through automatic water level monitoring, predict possible dangers, and transmit the data to the controlled system after processing to further take preventive or remedial flood discharge measures.

This gate can achieve efficient and automatic opening and closing, thereby enabling intelligent flood discharge from the tailings dam, ensuring the safety of people's lives and property, the production safety and economic security of enterprises, and protecting the environment, thus improving the reliability of tailings dam flood discharge.

[0077] Example 5

[0078] like Figure 5 As shown, based on Example 4, the calculation of the target flood discharge volume provided in this embodiment of the invention uses a radial basis function network, and the specific process includes:

[0079] S201: The input layer of the radial basis function network receives the current highest water level and warning water level of the tailings dam;

[0080] S202: The current highest water level and warning water level of the tailings dam are taken into the radial basis function, which exists in the hidden layer of the radial basis function network;

[0081] The expression for the radial basis functions is:

[0082]

[0083]

[0084] In the formula, N represents the input quantity as water level, and M... (k) (N) represents the k-th component of the radial basis function target discharge, N i φ represents the water level sample at time i. i (‖NN i ||) is represented as a basis function, η ik c represents the basis function weights of the k-th component corresponding to the target flood discharge volume; i The kernel width of the basis function at time i is represented by ||NN|. i ‖ represents the sample points N and N i The Euclidean distance between them; n represents the total number of water level samples;

[0085] In the training of radial basis functions, the matrix equation of the weight coefficient matrix η is expressed as:

[0086] η=φ -1 M

[0087] Where, φ -1 Let M represent the inverse function of the basis functions;

[0088] S203: The output layer of the radial basis function network outputs the target flood discharge volume under the input mode;

[0089] The working principle and beneficial effects of the above technical solution are as follows: In this embodiment, the input layer of the radial basis function network first receives the current highest water level and warning water level of the tailings dam; the current highest water level and warning water level of the tailings dam are then input into the radial basis function, which exists in the hidden layer of the radial basis function network; the output layer of the radial basis function network outputs the target flood discharge volume under the input mode; the flood discharge volume calculation module of the above solution uses the radial basis function network for calculation. The mapping from the input to the output space is nonlinear, while the output of the radial basis function network is linear with respect to the adjustable parameters. The weights of the radial basis function network are directly solved by the linear equation system, which greatly accelerates the learning speed and avoids the problem of local minima. It can learn from historical flood discharge volumes, reduce the difference between the predicted target flood discharge volume and the actual flood discharge volume, and effectively solve the nonlinearity of rainfall, minimizing the difference between the target flood discharge volume and the actual required flood discharge volume, reducing water resource waste and the impact on downstream areas.

[0090] Example 6

[0091] Based on Example 4, after the gate provided in this embodiment of the invention is opened, when the water level drops to the warning level, the water level monitoring module transmits the water level signal to the gate control module, which then automatically controls the gate of the diversion channel to close. The staff of the main control module can monitor the operation of the gate control module in real time through the intelligent control terminal main control system, and can also view the system's operating status through the network camera monitoring system. When the power system fails, the backup power supply can automatically switch on to provide power to the system. If the gate's lifting system and power system malfunction, the backup diesel engine and lifting system will come online to provide power for the opening and closing of the gate.

[0092] The working principle and beneficial effects of the above technical solution are as follows: After the gate is opened in this embodiment, when the water level drops to the warning level, the water level monitoring module transmits the water level signal to the gate control module, and then the gate control module automatically controls the gate of the diversion channel to close. The above solution achieves gate closure by monitoring changes in water level, which helps to improve the intelligent control capability of the intelligent diversion channel system, realizes the function of autonomous measurement and autonomous control, and reduces the cumbersome manual operation.
