Embodiment Construction
[0022] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0023] The present invention provides a method for automatic control of equipment coordination based on belt conveyor load distribution, which includes the following steps:
[0024] 1) Calculate and obtain the full-line load distribution data of the belt conveyor;
[0025] 2) According to the basic control information of the belt conveyor and the upstream belt conveyor, determine the starting safety distance L of the belt conveyor safe _ st and stop safety distance L safe _ sp ;
[0026] 3) When the belt conveyor has no load within the safety distance interval for starting, the belt conveyor has the starting condition along the coal flow, oth...

The invention relates to a device coordinated automatic control method based on the load distribution of a belt conveyor, which comprises the following steps of: calculating and obtaining the full line load distribution data of the belt conveyor; according to the basic control information of the belt conveyor and an upstream belt conveyor, determining a starting safety distance Lsafe_st and stopping safety distance Lsafe_sp of the belt conveyor; wherein, when no load exists in a starting safe distance range of the belt conveyor, the belt conveyor is provided with a starting condition in a direct coal flow, otherwise, the belt conveyor is not provided with the starting condition in the direct coal flow; when the belt conveyor is started in the direct coal flow, if material arrives at the stopping safe distance range, and a downstream belt conveyor fails to start normally, the belt conveyor should be stopped immediately. The method has the functions of automatic control, unattended operation and the like, reduces manual intervention, ensures reliable operation of the system, can achieve energy conservation and consumption reduction and improves production efficiency.
Description
Technical field: [0001] The invention relates to the field of safety technology of a coal mine belt conveyor monitoring system, in particular to an equipment cooperative automatic control method based on the load distribution of a belt conveyor. Background technique: [0002] The belt conveyor has high coal transportation efficiency and is the main equipment for coal flow transportation in mines. As the automation of coal mine production becomes higher and higher, users have more and more demands on the technology and intelligence of the on-site coal flow control system. high demands. [0003] The belt conveyor transportation monitoring system currently on the market can perform simple start-stop control on the belt conveyor, but there are still disadvantages such as poor safety, high energy consumption, and easy-to-wear equipment on site. The reasons for these problems are relatively complicated, but a large part of the factor is due to the lack of sufficient understanding...
