As shown in fig. 3 and 4, the system for detecting material blockage in a production line of a coal preparation plant may further include an inductive switch sensor 104, which is disposed at a second type monitoring point of the production line, wherein the inductive switch sensor 104 detects a material transportation state of the second type monitoring point and generates a switching value digital signal; the probability of blockage of the second type of monitoring points is less than that of the first type of monitoring points; the main control server 103 receives the switching value digital signal sent by the inductive switch sensor 104, and judges whether the second type of monitoring point is blocked and the blocking degree of the second type of monitoring point according to the switching value digital signal; the main control server 103 is further configured to obtain a detection result of the blockage of the production line after merging the judgment result of whether the first type monitoring point is blocked, the blockage degree of the first type monitoring point, the judgment result of whether the second type monitoring point is blocked, and the blockage degree of the second type monitoring point. The setting manner and the jam detection principle of the inductive switch sensor 104 can be implemented by referring to the conventional manner of detecting the switching value, and are not described in detail in this embodiment. In some embodiments, multiple types of sensors may be disposed at the same blockage point to detect the blockage point, and the actual transportation state of the blockage point is determined after the detection results of the multiple types of sensors are fused.
The mode that the main control server 103 fuses the blockage judgment results and the blockage degree of each blockage point can adopt simple summarization, and can store in a data table mode, so that the detection results of each blockage point on the whole production line can be recorded and archived and collected, and the detection results can be conveniently called and checked by workers.
In the above solution, there are various types of the switch sensor 104, and an appropriate type may be selected according to the setting position, taking the chute 202 as an example: a blocking switch is arranged in the chute; the outer gate-type limit travel switch or hall switch of installation of chute, adorn inboard infrared detection switch etc. outward. In the scheme, a video detection sensor or a combination of a plurality of detection sensors is arranged at a position easy to block, only a conventional blocking switch is arranged at other positions, the switching value detected by the switching sensor 104 is a digital value, the digital value is one of physical quantities, the change of the digital value is discontinuous in time and always occurs in a series of discrete moments, so the digital value is also called discrete value, which means the digital value is dispersed and has no intermediate value, and the digital value is a '0' or '1' signal simply. The video image is an analog quantity, and the analog quantity refers to a quantity of which the variable changes continuously in a certain range; i.e. can take any value (within a range of values) within a certain range (domain of definition). Therefore, the processing difficulty of the digital quantity is far smaller than that of the analog quantity, the switching value is set at some conventional blocking points (or positions where blocking is not easy to occur), the state of the blocking points is judged through the processing of the digital quantity, and the pressure brought to the server processing data quantity by adopting video image detection is avoided.
In the above solutions, as shown in fig. 5 and fig. 6, the controlled device may include a frequency converter 105, an input end of which is connected to an output end of the main control server 103, and an output end of which is connected to a control end of the conveying equipment 106 at the blockage point. Among them, the Variable-frequency Drive (VFD) is a power control device that applies frequency conversion technology and microelectronic technology and controls an ac motor by changing the frequency of the operating power supply of the motor. The frequency converter 105 is configured to receive the control signal sent by the main control server 103, and reduce the lower frequency limit threshold from the reduced operating frequency of the transportation device 106 to the transportation device 106 according to the control signal. The main control server 103 may pre-store a mapping relationship between the control signal and the blockage detection result of the blockage point, for example, after it is determined that the blockage point is blocked, each large-flow transportation device may be controlled to reduce the operation rate, so as to reduce the amount of the material entering the blockage point. Taking fig. 6 as an example, when the chute 202 is blocked, the "n-1" frequency converter 1051 will reduce the operating frequency of the "n-1" conveyor to the minimum, and the "n" frequency converter 1052 will reduce the operating frequency of the "n" conveyor to the minimum, thereby reducing the amount of material entering the hopper 201, and thus reducing the amount of material entering the chute 202. That is, according to the scheme, when the production line is slightly blocked, the plurality of conveying devices 106 at the upstream of the blocking point can be controlled to reduce the operation frequency, so that the inflow material amount entering the current blocking point is reduced, the blockage is processed under the condition that the accumulated material amount is less, and the production accident caused by material accumulation is reduced. According to the scheme, the full-line large-flow conveying equipment before the blocking point can operate in a speed reduction mode, the material receiving amount of upstream equipment is greatly reduced, the processing time is prolonged for processing the blocking materials of the blocking point, the abrasion and the energy consumption of the equipment are reduced, and slight blocking faults of the blocking point in a production line are eliminated in an initial state.
Preferably, in some embodiments, the controlled device may further include a vibration component 108, and the vibration component 108 is connected to the output end of the master control server 103 through the power distribution control cabinet 107.

This scheme application is opened air bubble and is replaced indisputable pincers, iron hammer instrument, utilizes aerodynamic's mode to dredge the jam point. The method is the same as the air cannon in that a vibration motor is arranged outside a blocking point, the vibration of the blocking point is applied, the position of the coal blocks is changed, and the principle of vibration mechanics is applied to dredge the blocking point. Taking chute 202 as an example, vibrating motor 1081 sets up the outer wall at chute 202, air bubble 1082 sets up inside chute 202, after detecting that the chute blocks up, the mediation processing apparatus automatic start of main control server 103 control chute department, vibrating motor 1081 sends the vibrational force to the chute wall, air bubble 1082 dredges the jam material of jam point automatically, after the jam processing finishes, main control server 103 can receive the normal signal of system, main control server 103 can stop the operation of jam processing apparatus automatically, all production line equipment shift to normal production state.

Specifically, the alarm component can be speaker, warning light etc. and the form through broadcast pronunciation or scintillation warning light makes the site work personnel learn the position that takes place to block up, and the suggestion is patrolled to the material jam point and is patrolled nearby patrolled personnel, and the auxiliary treatment guarantees that to block up the chute and finishes fast.
In some embodiments, the system for detecting material blockage in a production line of a coal preparation plant further includes a conveying device 106, a control end of the conveying device 106 is connected to an output end of the main control server 103, the conveying device 106 receives a control signal sent by the main control server 103, and if the control signal indicates that a shutdown is required, the conveying device 106 stops working. The jam degree may be too high due to the shutdown, or a sensor detecting the jam may fail or the normal state may still not be recovered after the jam is processed, and the control signal corresponding to the mechanism under different conditions may be stored in the main control server 103 in advance.

Secondly, the processing mode after the blockage is detected, if the blockage trigger signal is detected, the controlled equipment is controlled in a linkage control mode, the running frequency of the conveying equipment is reduced, and a vibration part arranged at a blockage point can be started to process the materials causing the blockage. If the blockage is serious, the system automatically controls the stop and informs related personnel to process the production accident of the blockage.
