Detailed Description
As shown in fig. 1, the present invention discloses a method for resolving the conflict and confusion of multiple sending parties sending the same port, which is implemented based on a system that includes a controlled device, a port module and a plurality of master control devices; and the master control equipment is in communication connection with the controlled equipment through the port module. The port module is internally provided with a transmitting and receiving unit, a window reading unit and a plurality of communication units, the transmitting and receiving unit is connected with controlled equipment through an RS485 bus, the transmitting and receiving unit is connected with the window reading unit, and the window reading unit is connected with the plurality of communication units through different channels and is in communication connection with the main control equipment.
The solution is as follows:
the master control equipment establishes connection with a corresponding communication unit in the port module and sends a control instruction to the communication unit;
the window reading unit establishes a sending queue, the reading communication unit obtains a control instruction sent by the main control equipment, and the control instruction and the sender information are added into the sending queue as a data packet; the data packet comprises a first attribute and a second attribute, wherein the first attribute represents a sender, and the second attribute represents a control instruction sent by the sender;
the sending and receiving unit establishes a sending thread, takes out a data packet from the sending queue and analyzes the data packet; then sending the analyzed attribute II, namely the control instruction, to controlled equipment through an RS485 bus;
the controlled device receives and processes the control instruction and returns processing result data to the sending and receiving unit through the RS485 bus;
after receiving the processing result data, the sending and receiving unit identifies a sending party according to the analyzed attribute I, then sends the processing result data to the main control equipment through a corresponding channel and a communication module, and the sending thread is finished;
