When the conveyor is operated, the start time of the conveyor in a certain process state is usually set to a fixed value, that is, the start time of the conveyor in the process state is fixed, and the time from stopping the conveyor to setting the transfer rate is a fixed value. However, different power losses can occur due to different climatic conditions in different seasons, resulting in different start times under different conditions. The start time in the standard state (non-severe state) range may be taken as the standard start time range. In a severe working state, the starting time of the conveyor is longer than the value in the standard starting time range, that is, the starting acceleration of the conveyor in the severe working state is smaller than that in the normal state. According to the running process of the conveyor, the starting process is not allowed to be loaded with materials, which results in waste of energy during the starting process. The standard state range refers to a condition range of the conveyor keeping a good working state, for example, the working environment temperature is 20-35 ℃, the working environment temperature of a severe working state is outside the temperature range, and specific parameters are determined by the design characteristics of the conveyor belt.

Detailed Description
The following will fully explain the driving control method of a belt conveyor provided by the present invention in detail with reference to the following embodiments. The following examples are illustrative only and are not to be construed as limiting the invention.
A belt conveyor drive control method defines a standard state range: the belt conveyor is started within the standard starting time t, the power required by the normal operation of the belt conveyor is P0, and P isLabel 2＜P0＜PLabel 1，t0＜t＜t1Wherein, t0、t1The values are fixed values and are respectively a lower limit value and an upper limit value of t; pLabel 2＜PLabel 1，PLabel 1、PLabel 2The values are fixed values and are respectively an upper limit value and a lower limit value of P0;
the belt conveyor is connected with three motors which drive the conveyor together, the three motors are connected with the PLC, and further, the three motors are respectively provided with a power detection device which is electrically connected with the PLC. The control method comprises the following steps:
step a: will Pn1、Pn2And Pn3Inputting the data into a PLC;
wherein, Pn1、Pn2And Pn3And the active power of the three motors in normal operation after the three motors are started for the nth time respectively.
Step b: PLC calls Pn1、Pn2And Pn3And calculating the value of P, wherein P ═ Pn1+Pn2+Pn3；
Step c: p and P areLabel 1、PLabel 2Determination of the starting time t' after the comparison: if P>PLabel 1Then, set t 'such that t' > t0(ii) a If P<PLabel 2If so, setting t 'to ensure that t' is less than t 1;
step d: when the three motors are started for the (n + 1) th time, the PLC controls the three motors to finish starting within the time t' so as to drive the conveyor to start.
The standard starting time t is the starting time from stopping to normally running of the belt conveyor at the ambient temperature of 20-35 ℃. The energy consumption of the conveyor changes with working environment parameters (such as environment temperature), and if the working environment becomes severe, the resistance of the belt conveyor, which needs to be overcome from stopping to normal operation, is increased, that is, the power loss of the conveyor is increased.
The conveyor comprises a conveying belt, and in order to ensure the conveying performance of the conveying belt, the conveying speed of the conveying belt is generally set to be a fixed value, namely the power consumed by the conveying belt is not changed. The normal operation of the belt conveyor means that the conveying speed of the conveying belt reaches a set value.
PLabel 1＝Pd+Ph1Wherein P isdThe power consumed by the conveyer belt is a fixed value; ph1Power loss when the upper limit value is set for P0.
PLabel 2＝Pd+Ph2Wherein P ish2Power loss when the lower limit is taken for P0;
P＝Pd+P(n)hwhere P is the actual power supplied to the conveyor, P (n)hAnd after the three motors are started for the nth time, the power is consumed when the conveyor normally runs.
If P>PLabel 1Then P (n)h>Ph1In comparison with the standard state range, when the power loss of the conveyor is increased when the conveyor is normally operated after the nth start of the three motors, the following adjustments may be made: when the conveyor is started for the (n + 1) th time, the start time of the conveyor is set to be longer, so that the start process becomes longer.
If P<PLabel 2Then P (n)h＜Ph2When the power loss is reduced after the n-th starting of the three motors and the normal operation of the conveyor, compared with the standard state range, the power loss is reducedThe following adjustments may be made: when the conveyor is started for the (n + 1) th time, the starting time of the conveyor is set to be shorter, so that the starting process is shortened, namely the no-load time of the conveyor belt is shortened, and the energy loss in the starting process is correspondingly reduced.
The adjustment of the starting time of the conveyor is realized by adjusting the starting time of the motor, the starting time of the motor is the time from the stop to the normal operation of the conveyor belt driven by the motor, the motor is connected with a frequency converter, a hydraulic device or a soft starter, and the starting time of the motor is controlled by the frequency converter, the hydraulic device or the soft starter.
The basic logic of the above derivation relationship is: when the P is larger than the upper limit value of P0 when the conveyor runs for the nth time, increasing the starting acceleration time when the conveyor runs for the (n + 1) th time; less than the lower limit of P0 reduces the start-up acceleration time.
Finally, it must be said here that: the above embodiments are only used for further detailed description of the technical solutions of the present invention, and should not be understood as limiting the scope of the present invention, and the insubstantial modifications and adaptations made by those skilled in the art according to the above descriptions of the present invention are within the scope of the present invention.
