Description

Technical Field

[0001] The utility model relates to the technical field of belt monitoring, in particular to a belt centralized control monitoring device. Background Art

[0002] The underground belt conveyor of a coal mine is the main artery for transporting raw coal in the mine. The stable operation of the belt conveyor is related to the output of the mine. During the production process, the coal flow underground in the coal mine is usually very long and consists of multiple transport belts. During the belt transportation process, if there are problems such as uneven coal discharge, jamming, reduced belt tension, and excessive hydraulic oil temperature, which affect the progress of belt transportation, it is necessary to stop the machine for inspection and maintenance in time. Most of the existing belt controllers can only control the start and stop of the belt, and cannot achieve all-round monitoring of the belt. Only a few belt controllers have the function of monitoring some performance indicators of the belt, but can only monitor the single controlled belt. Underground transportation in coal mines involves the coordinated work of multiple belt conveyors. If the coordinated belt conveyors cannot be monitored at the same time, once one of the belt conveyors fails, it will cause the other belt conveyor to be affected and fail. Therefore, the present application proposes a belt centralized control monitoring device to centrally monitor the belt and promptly discover the safety hazards in the belt transportation process.

[0018] The present invention is further described in detail below through the accompanying drawings and specific implementation methods.

[0019] like Figure 1 As shown, an embodiment of the utility model provides a belt centralized control monitoring device, including an Ethernet communication module 2 connected to the belt controller, a switch quantity acquisition interface 3, a main controller 1 and an alarm module 4;

[0020] The Ethernet communication module includes multiple network ports RJ45 and a switching circuit, and the switching circuit uses a DM9000A chip; the input end of each network port is connected to a belt controller, and the output end is connected to the input end of the switching circuit, and the output interface of the switching circuit is connected to the data acquisition interface of the main controller; the main control chip of the main controller of this application adopts the STM32F series. The main control chip is STM32F103ZET6, and an ARM embedded chip such as AT91RM9200 can also be used. Figure 2 As shown in the figure, the SD0-SD15 pins of the DM9000A chip correspond to the FSMC0-FSMC15 pins of the main control chip, and the network port is used to collect the data of each belt controller, such as the motor current, belt voltage, belt temperature and other parameters; through the preset threshold range, it is judged whether these data are normal. When some parameters are found to exceed the preset range, it indicates that the belt conveyor will fail. The data output end of the main controller is connected to the alarm module. The alarm module can be controlled to alarm.

[0021] On the other hand, for the detection quantities that cannot be obtained in the belt controller, multiple switch quantity acquisition interfaces are set up in this application, including 4-way DI interfaces, which can collect 0-5V voltage quantities; 4-way AI interfaces, which can collect 4-20mA current quantities. For data that cannot be collected through the belt controller, the sensor can be directly connected to the centralized control device of this application.

[0022] For example: the switch quantity acquisition interface connects the belt conveyor's tension meter, hydraulic oil temperature sensor, limit sensor, etc. to obtain tension data, temperature data, position data, etc.; monitors whether the belt conveyor has insufficient or excessive tension, excessive temperature, or deviation, and performs separate data collection for old belt conveyors that cannot use the controller for sensor data collection. It is compatible with most belt conveyors.

[0023] It also includes a CAN communication module and a serial communication module, and the CAN communication module and the serial communication module are respectively connected to the main controller. In this application, the CAN communication module and the serial communication module are reserved ports, and other equipment in the field of belt transportation or coal mine transportation, such as a transfer machine, etc., can communicate by setting the CAN communication module and the serial communication module.

[0024] like Figure 3 As shown, there are multiple alarm modules, each of which includes a solenoid valve and an alarm device. The solenoid valve is connected to the alarm device, and the alarm device includes an audible and visual alarm or an electric bell.

[0025] The data output end of the main controller is connected to the solenoid valve by connecting a delay relay. In the present application, since it involves centralized monitoring of multiple belt controllers, different alarm modes can be set for each belt controller to prompt the staff which one is faulty. Therefore, the main controller outputs a switch signal to control the on and off of the delay relay, and the delay relay controls the solenoid valve to be attracted or turned off according to the set delay time, so that different alarm modules can be alarmed at different frequencies. For example, when the P1 end of the main controller outputs a high level, the delay relay KM1 is turned on. At this time, the delay relay KM1 is set to be turned off after a delay of 1S, so the solenoid valve is disconnected after a delay of 1S, and the alarm bell output by the alarm module is a short ringtone lasting 1S. When the P2 end of the main controller outputs a high level, the delay relay KM2 is turned on. At this time, the delay relay KM2 is set to be turned off after a delay of 5S, so the solenoid valve is disconnected after a delay of 5S, and the alarm bell output by the alarm module is a long ringtone lasting 5S, which realizes the distinguishing alarms for different belt controllers or different faults in turn.

[0026] Obviously, the above embodiments are only examples for clear explanation, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention of the utility model.
