The term "comprises/comprising" and any derivatives thereof, as used in this application, are intended to cover a non-exclusive inclusion.
As shown in fig. 1, an embodiment of the present application provides a method for sending an analog data frame, including:
step S102, acquiring analog data frames of a plurality of substations, wherein the analog data frames comprise data for testing functions of the substations, and the substations comprise one or more devices to be tested;
and step S104, sending the analog data frame and the corresponding control instruction to the substation through the master station, wherein the master station is electrically connected with the substation.
It should be noted that the master station in the embodiment of the present application may be an electric control box, a Controller, and the like in a coal mining machine control system, and may be implemented in a mode of a single chip microcomputer and a Programmable Logic Controller (PLC), and respectively connected to a computer terminal and a CAN bus. The analog data frame CAN be generated by the computer end and then transmitted to the master station, and the master station distributes the analog data frame to each substation connected to the CAN bus.
There are many devices to be tested in the coal mining machine electrical system, such as sensors, frequency converters, motor protectors, ac contactors, remote controllers, etc., wherein there are hundreds of sensors, such as Temperature sensors, Positive Temperature Coefficient (PTC) sensors, pressure sensors, and flow sensors. And connecting the equipment to be tested to the CAN bus to exist in a substation form. A substation may include a frequency converter or an ac contactor, and may also include one or more sensors. The test function is completed through the operation of the master station on the substation, the packaging mode of the data frames of the devices to be tested is required to be embedded into software, and due to different data frame composition modes of various devices to be tested, if each device to be tested writes a data frame packaging program, code redundancy, system complexity and poor repeatability can be caused, and system maintenance such as adding and deleting the devices to be tested, modifying the position of the data frame, modifying COB-ID (node number) and the like is not facilitated for factory workers.
The length of a CAN data frame used for communication of a common coal mining machine is 13 bytes, the length of the first byte is the length of the data frame, the lengths of the four bytes are COB-ID, and the last 8 bytes are Process Data Object (PDO) areas. Taking a sensor as an example, a common data encapsulation mode is to store data according to data positions on a sensor specification, for example, a data frame of a liquid level sensor of a left pump and a right pump shown in fig. 2, the sensor is a 16-bit sensor, occupies exactly two bytes, and can be configured in a word size + high-low byte mode. The PDO is used for transmitting real-time data, and is the most important data transmission mode in CANopen. The transmission speed is high because the transmission of the PDO does not need to be answered and the length of the PDO can be less than 8 bytes. However, if the data frame of the same substation contains sensor data with 16 bits, such as 12-bit sensor, the data in one sensor spans two word sizes, and thus, the data encapsulation of all types of sensors cannot be satisfied by the word size. As shown in fig. 3, the number of turns spans two word sizes, and it appears that the values of the two parameters are not continuously mixed in one byte. If this special case cannot be solved, the data frame encapsulation program can only be written for such sensors or substations individually.
In one embodiment, the acquiring analog data frames of a plurality of outstations includes: acquiring an initial data frame of the equipment to be tested when the equipment to be tested leaves a factory, wherein the initial data frame is in a small-end format; an analog data frame is generated using the initial data frame, wherein the analog data frame has an offset relative to the initial data frame. Note that the offset amount here may be 0.
In an embodiment, the generating of the analog data frame by using the initial data frame may be implemented by:
s1, judging whether the initial data frame meets a preset system (for example, whether the initial data frame is a 16-bit sensor);
s2, determining the initial data frame as an analog data frame (corresponding to an offset of 0) when the initial data frame satisfies a predetermined scale;
and S3, under the condition that the initial data frame does not meet the preset system (for example, the initial data frame comprises a 12-bit sensor), shifting the initial data frame according to the offset to obtain the analog data frame.
In an embodiment, the shifting the initial data frame by the offset to obtain the analog data frame may be implemented by:
s1, converting the initial data frame into a middle data frame in a big-end format, and obtaining the offset of the middle data frame relative to the initial data frame;
s2, writing the offset of the equipment to be tested into a configuration file of the equipment to be tested;
s3, reading the configuration file, and carrying out data bit offset on the intermediate data frame according to the offset to obtain the offset data frame;
and S4, converting the shifted data frame into a small-end format to obtain an analog data frame.
Fig. 4 is a schematic diagram of optional substation data frame encapsulation based on offset according to an embodiment of the present application, and as shown in fig. 4, taking a sensor as an example, a data frame format (generally, a small-end format) of the sensor when leaving a factory is first obtained; then converting the data into a format of a large-end data frame to obtain offset; then filling and writing the offset of each sensor into a configuration file of a bottom layer; the data encapsulation program can automatically read the configuration information of all the sensors and carry out data bit offset; and finally, the converted small-end data frames are transmitted to a CAN-NET-2EU (a CAN-NET conversion module for converting the data frames generated by the computer into CAN data frame formats) in a byte stream mode, and the module CAN convert the byte stream into CAN data frames and transmit the CAN data frames to a master station (equivalent to a coal mining machine controller).
Fig. 5 is a flowchart of an alternative offset-based outstation data frame encapsulation process according to an embodiment of the present application, and as shown in fig. 5, the offset-based outstation data frame encapsulation process includes the following steps:
s501, acquiring a data frame format of the sensor when the sensor leaves the factory (the sensor is taken as an example for explanation here, and may be other devices to be tested);
s502, determining whether the factory data frame satisfies 16 bits (here, the preset scale is set to 16, or other scales are set), if yes, executing S503, and if no, executing S5021;
s5021, converting the factory data frame into a large-end data frame, calculating the offset, and executing S5022;
s5022, filling the offset into the bottom layer configuration file, and executing S5023;
s5023, reading the sensor configuration file information by a packaging program in the computer, carrying out data bit offset, and executing S5024;
s5024, converting the shifted data into small-end data frames, and executing S503;
s503, sending the data frame obtained in the last step to a CAN-NET-2EU to be converted into a CAN data frame;
and S504, sending the CAN data frame to a coal mining machine controller.
