Utility model content
Technical problem to be solved in the utility model is, a kind of mine down-hole electric locomotive stringing segmentation automatic power control system is provided, and realize the sectional power supply control of mine down-hole electric locomotive stringing, and cost is low, dependable performance.
The technical solution adopted in the utility model is as follows:
A kind of mine down-hole electric locomotive stringing segmentation automatic power control system, it comprises electric locomotive track, run on the electric locomotive on electric locomotive track and be positioned at bus and the air wire of electric locomotive top, the power taking bow of electric locomotive is connected with described air wire, it is characterized in that: described air wire comprises some section leads, between adjacent wires, is connected by insulation rod; Each section lead section of living in is provided with a master controller and at least one localization machine; Described master controller is connected with described bus and is connected with the air wire wire of section of living in; Localization machine in same section is arranged on respectively in the wall of section of living in and is connected with the master controller in this section respectively; Also comprise the vehicle-mounted machine being arranged on electric locomotive, communication connection mutually between described vehicle-mounted machine and described localization machine.
Good effect of the present utility model is:
The first, the utility model utilizes wireless remote control transmitting and receives signal system, and signal is unimpeded, is not subject to the impact of bow, stringing, greatly reduces fault rate, has improved operating efficiency.And system is not affected by downhole powder dust, wet environment, the longer service life of electronic devices and components.
The second, the utility model has reduced the electrification time of stringing, not only save electric energy, ensure the reliable and stable disconnected transmission operation of each stringing section, and operating electrical machines car is time out of service, if while forgetting to draw electric locomotive bow, the native system delay adjustments time, by stringing power-off, has been guaranteed the safety of the person and equipment.
Three, the utlity model has investment little, be easy to promote the outstanding feature that operation expense is low.
Brief description of the drawings
Fig. 1 is structure of the present utility model and principle of work schematic diagram.
Detailed description of the invention
Further illustrate the utility model below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model comprises electric locomotive track 8, runs on the electric locomotive 6 on electric locomotive track and is positioned at bus 2 and the air wire 9 of electric locomotive 6 tops, and the power taking bow 5 of electric locomotive 6 is connected with described air wire 9.
Described air wire 9 comprises some section leads, between adjacent wires, is connected by insulation rod 7.Each section lead section of living in is provided with a master controller 1 and at least one localization machine 3.Described master controller 1 is connected with described bus 2 and is connected with the air wire wire of section of living in.Localization machine 3 in same section is arranged on respectively in the wall of section of living in and is connected with the master controller 1 in this section respectively.Also comprise the vehicle-mounted machine 4 being arranged on electric locomotive 6, described vehicle-mounted machine 4 is communicated by letter mutually by wireless signal with described localization machine 3.
Wherein main control system 1 major part: controller MCU, vacuum contactor, for the Hall current sensor of detecting motor car working current, for difference mode signal interface of being connected with localization machine 3 etc.Wherein vacuum contactor adopts large electric current (400A) contactless switch of hermetically sealed high pressure (450V), to adapt to downhole powder dust humidity and high-power working environment.Difference mode signal interface adopts power supply separately; when providing reliable and stable power supply for localization machine, be provided with overvoltage and overcurrent protection; prevent the impacts of error state on main frame such as cable short circuit, leakage; interface is with current forms checking system signal line states; in the time there is forward current path between two signal wire (SW)s, think that localization machine moves; by notification controller MCU after signal isolation, complete next step action by controller MCU.Difference mode signal interface provides power supply for wall hanging machine, and detection signal line states, when forward current appears in signal wire (SW), controller MCU transformation working pattern is to power supply state, closed vacuum contactor is that stringing powers on, testing stand line current simultaneously, when signal wire (SW) current signal disappears, main frame enters time delay state, and continue testing stand line current, electric current continues after disappearance setting-up time, and controller MCU controls vacuum contactor and disconnects, stringing power down.
Wherein vehicle-mounted machine 4 major parts: wireless transmitter module, magnetic induction sensor etc.Wherein wireless transmitter module is 315MHZ wireless transmitter module, have that transmitting frequency is stable, emissive power large, dormancy is from plurality of advantages such as power consumption are low, magnetic induction sensor is installed on power taking and bends 5 places, be combined with strong magnetic and can perception power taking bend 5 states, there is highly sensitive, the many advantages such as reliability is high, antidetonation, " zero-power ", be combined with wireless module, overcome in the past that similar products stand-by power consumption was high, speed of response slow or need many deficiencies such as manual activation.After the chaufeur of electric locomotive 6 is in place, according to driving code, power taking is bent to 5 set, trigger magnetic induction sensor, magnetic induction sensor is in conducting state, for wireless transmitter module provides current path, transmitter module is launched code signal according to preset frequency, receives for localization machine 3.
Wherein localization machine 3 major parts: 315MHZ superregeneration wireless receiver; the receiving sensitivity of can provide under the stand-by power consumption of 7mA-103dBm; and be provided with protection and optimized circuit for long apart from power supply and signal transmission, greatly degree has improved communication reliability.Localization machine 3 is fixedly installed in wall, by the power taking of host signal interface, receives by wireless receiver wireless signal the decoding that vehicle-mounted machine 4 is sent, and after coupling, beams back master controller 1 by signaling interface.
When electric locomotive 6 is wanted to travel, chaufeur enters operator's compartment, power taking is bent to 5 set, triggering is arranged on the magnetic induction sensor of power taking bow position, vehicle-mounted machine 4 will be transmitted into around space, electric locomotive place with wireless mode after Signal coding, the localization machine that is installed in wall place receives and decodes, identification rear drive signaling interface, complete the signal transmission from wireless to wired, wired segment signal terminal is controller MCU, and controller MCU drives vacuum contactor adhesive, closed bus and this section stringing, this section stringing successfully powers on, and electric locomotive 6 is wheeled.
In electric locomotive 6 driving process, master controller 1 detects the electric locomotive signal being transmitted by signaling interface and the electric locomotive working current detecting by Hall current sensor simultaneously, when disappearing simultaneously, both continue after setting-up time, main frame thinks that electric locomotive has sailed out of this section or stopped in this section, controller MCU discharges vacuum contactor, stringing power down, wait electric locomotive 6 is sent power on signal again.In the time running into two section stringing intersections in electric locomotive 6 driving process, wireless signal in the transmitting of this section tail place can be received by lower curtate localization machine, the pre-power transmission of lower curtate stringing waits for that electric locomotive 6 sails into, electric locomotive 6 is crossed after segmentation, front segmented current and blackout, power down after the delay adjustments time (such as 10 seconds).
