The technical scheme adopted by the invention is as follows:
a method for controlling the graded drainage of the liquid level of an ore bin based on the peak-valley period comprises the steps of collecting the liquid level information of a water bin through a liquid level sensor by adopting an automatic control technology, integrating other related parameters, scheduling all water pumps to work in turn in real time, and determining the number of the water pumps to be started and stopped according to the actual situation on site. The running state of the water pump and the detection value of the sensor are transmitted back to the upper computer monitoring system on the ground through a communication network.
The automatic control system sets the limit value of the water level of the n-level water sump: lower limit value (H)0) Class 1 starting value (H)1) Class 2 starting value (H)2) … n class starting value (H)n) Upper limit value (V)m) And H is0<H1<H2…<Vn<Vm。
And the PLC receives the liquid level information H of the water sump of the liquid level sensor and determines the number of the water pumps which are started according to the peak-valley time period of the liquid level sensor. When the liquid level H of the water sump is equal to H0When the water level of the water sump is equal to H, all the water pumps stop workingmAnd (5) alarming. When the system is in the electricity utilization valley, the system is based on the level value H of the water sumpiStarting the set number niThe water pump of (1); when the system is in the peak of electricity utilization, the system calculates the rising speed of the liquid level from the current liquid level H to the upper-level liquid level H according to the liquid level value H of the water sump and by calculating the rising speed of the liquid leveli+1Time t of the limit valueiAnd compared with the time t of reaching the trough period when tiT, keeping the original water pump drainage, when ti<t, increasing the number of start-up settings to niThe water pump of (2) drains water.
The control method has simple flow, well utilizes the peak-valley time period, saves the drainage cost and has obvious economic benefit.

FIG. 1 is a flow chart of a method for controlling the graded drainage of the liquid level of an ore bin based on peak-valley time periods.
Detailed Description
As shown in fig. 1, a flow chart of a method for controlling graded drainage of liquid level in a mine bin based on peak-valley period, the method uses a control system which mainly comprises a ground monitoring center, an underground PLC control center and an Ethernet data communication network, the control system mainly adopts PLC control technology, carries out unattended automatic control on 4 underground drainage pumps through an industrial Ethernet communication interface, carries out real-time monitoring, control and alarm on the operation state of the drainage pumps by using a touch screen, and transmits related data to the ground control center in real time through the industrial Ethernet, thereby realizing on-line monitoring and scheduling of the drainage system.
The automatic control system collects the water level H of the water sump through the liquid level sensor, dispatches all the water pumps to work in turn in real time according to the peak-valley period of the water sump, and determines the starting number of the water pumps. The running state of the water pump and the detection value of the sensor are transmitted back to the upper computer monitoring system on the ground through a communication network.
The control method sets the limit value of the water level of the 5-level water sump: lower limit value (H)0) Class 1 starting value (H)1) Class 2 starting value (H)2) Class 3 starting value (H)3) Upper limit value (H)m) And H is0<H1<H2<H3<Hm。
When the liquid level H of the water sump is at a first-level starting value (H)1) When the power grid is in the peak-valley period, all the water pumps are not started, and drainage operation is not needed.
When the liquid level of the water sump H2>H≧H1And the power grid is in the valley period, starting a water pump to drain; when the liquid level of the water sump H2>H≧ H1And the power grid is in the peak period, the water pump is not started for draining water temporarily, the PLC reads the level value of the water sump, and calculates the rising speed of the liquid level to H by calculating the rising speed of the liquid level2Time t of1And compared with the time t of reaching the trough period when t1Not less than t, all water pumps are not started, and when t1<And t, starting a water pump to drain.
When the liquid level of the water sump H3>H≧H2And the electric network is in the valley period, start two water pumps to drain; when the liquid level of the water sump H3>H≧H2And the power grid is in the peak period, the PLC reads the level value of the water sump, and calculates the rising speed of the liquid level to H by calculating the rising speed of the liquid level3Time t of2And compared with the time t of reaching the trough period when t2≧t，Keeping one water pump to drain when t2<And t, additionally starting one water pump for draining, namely starting two water pumps for draining.
When the liquid level of the water sump Hm>H≧H3And the power grid is in the valley period, three water pumps are started to drain water; when the liquid level of the water sump H4>H ≧H3And the power grid is in the peak period, the PLC reads the level value of the water sump, and calculates the rising speed of the liquid level to H by calculating the rising speed of the liquid levelmTime t of3And compared with the time t of reaching the trough period when t3T, keeping two water pumps to drain when t is equal to3<And t, additionally starting one water pump for draining, namely starting three water pumps for draining.
When the liquid level decreases to the lower limit value (H)0) And when the water pump works, all the water pumps stop working.
When the drainage system starts three water pumps to drain, the liquid level of the water sump still continues to rise, or the liquid level of the water sump reaches an upper limit value HmAnd the system sends out an alarm signal.
