Description

Technical Field

[0001] The present invention relates to the field of rail transportation technology, and in particular to a rail locomotive dual-machine coupling method, system, equipment and medium. Background Art

[0002] In the existing underground metal mining system, locomotive rail transportation is an indispensable link in many mine transportation and a key factor in determining the output of the mine. Underground locomotive transportation is divided into double locomotive and single locomotive transportation. In the underground flat circular yard, locomotives generally operate in a single direction.

[0003] In a non-circular flat yard, rail locomotive transportation uses dual locomotive transportation. In dual locomotive transportation, each locomotive cockpit is driven by one driver, which requires communication and coordination between the two locomotives during operation. However, since the length of the locomotive is generally 40-60 meters, the drivers of both locomotives cannot grasp the specific situation of the other party. In this case, it is urgent to realize the dual-locomotive reconnection.

[0004] In a non-circular flat yard, multiple rail locomotives are required to work, and each rail locomotive uses dual locomotives for transportation. When the driver needs to stop or start, different whistles are used to warn. Therefore, the rail locomotives cannot exert the maximum efficiency of the two locomotives, and this method cannot complete the same frequency given operation of the dual-locomotive locomotives, as well as the dual-machine braking in an emergency, etc., resulting in poor results when multiple rail locomotives are working. Summary of the invention

[0005] The purpose of the present invention is to provide a method, system, equipment and medium for coupling two locomotives on a railroad in order to address the deficiencies of the above-mentioned prior art and solve the problem that the locomotives in the prior art cannot exert the maximum efficiency of the two locomotives, and this method cannot complete the same-frequency given operation of the dual-locomotive electric locomotives, as well as the dual-machine braking in an emergency, resulting in poor working effects of multiple railroad electric locomotives.

[0012] Preferably, the switch quantity input and output channels and the analog quantity input and output channels of the wireless remote module are electrically isolated from the module core control unit.

[0013] Preferably, among the switch value input and output channels, the number of switch value input channels and switch value output channels is consistent and corresponds one to one.

[0014] Preferably, in the analog input and output channels, the number of analog input channels is consistent with that of analog output channels, and supports 0V to 10V voltage signal input.

[0029] The following is a clear and complete description of the technical solutions of the embodiments of the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all examples. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0030] like Figure 5 As shown, the present invention provides a method for reconnecting two locomotives, which specifically includes the following steps:

[0031] Step S1: multiple electric locomotives are arranged on the underground plane.

[0032] Step S2: Install a wireless remote module on each locomotive, and pair the locomotives by matching any two locomotives through dialing frequencies.

[0033] like Figure 1 As shown, the wireless remote module has the wireless transmission of switch signals and analog signals, supports 3 switch inputs and 3 switch outputs for forward, reverse and brake, supports 1 0V~10V analog input and output; supports signal transmission between modules, supports one-to-one, and remote (within 100m of the locomotive) connection when the dip switch switches to the local effective mode.

[0034] A set of wireless remote module equipment is installed on each locomotive to complete the remote communication between locomotives. The wireless module is embedded with a high-speed single-chip microcomputer and adopts the latest high-performance radio frequency chip, reliable transmission mechanism, maximum transmission power of 500mw, working frequency band: 433MHz, or 470MHz, 868MHz, 915MHz optional, and the communication distance in a visible environment can reach 100m. The switch input and output channels and analog output channels are electrically isolated from the module core control unit and have strong anti-interference ability. Figure 2 and Figure 3 shown.

[0035] The switch quantity input and output channels and analog quantity input and output channels of the wireless remote module are electrically isolated from the module core control unit.

[0036] In the switch input and output channels, the number of switch input channels and switch output channels is consistent and corresponds one to one.

[0037] In one embodiment, there are 4 switch input channels, namely DI1, DI2, DI3, and DI4, and the common end is C1; there are 4 switch output channels, namely DO1, DO2, DO3, and DO4, and C2 is the common end.

[0038] In the analog input and output channels, the number of analog input channels and analog output channels is the same, and they support 0~10V voltage signal input.

[0039] In one embodiment, the analog input has one channel AI1, which supports 0V to 10V voltage signal input, and the analog output has one channel AO1, which supports 0V to 10V voltage signal input. The analog input channel and output channel are connected to the voltage signal in the following ways: differential input, where the two ends of the signal are connected to two differential input pins respectively. This method can effectively suppress common mode interference and is suitable for environments with long signal transmission distances or strong interference.

[0040] Step S3: After pairing is completed, the electric locomotives are reconnected and the locomotives in the group are synchronized and operated through remote control of both parties; the synchronization content includes: the front car forward input-the rear car forward output, the front car reverse input-the rear car reverse output, the front car brake input-the rear car brake output, the front car reset input-the rear car reset output, the front car speed input-the rear car speed output; when the rear car is valid, the front car is also valid. The grouping locomotive can select any electric locomotive in the system.

[0041] Each marshaling consists of two electric locomotives (one for the front and one for the rear). Each marshaling does not affect each other. Each marshaling has a different communication frequency band, such as Figure 4 shown.

[0042] In one embodiment, Figure 4 As shown, according to the above locomotive formation, the position synchronization and synchronous operation of each locomotive group (two locomotives) can be achieved. After the locomotives and the mine cars are connected, one locomotive can be operated by one person, while reducing the braking distance, improving the pass rate, reducing slippage, and improving system safety and transportation production efficiency.

[0045] The present invention also provides a computer device, including a memory and a processor, wherein a program is stored in the memory, and when the program is executed by the processor, the processor executes the steps of a method for reconnecting two locomotives.

[0046] In accordance with the disclosed embodiments, a computing device may communicate with one or more external devices (e.g., keyboards, pointing devices, Bluetooth communications, etc.), or with any device (e.g., routers, modems, etc.) that enables a computing device to communicate with one or more other computing devices.

[0047] The present invention also provides a storage medium on which a computer program is stored. When the computer program is executed by a processor, the steps of a method for reconnecting two locomotives of a railway locomotive are implemented.
