Abstract
A kind of adopt CAN communication technology realize Coal Transportation suddenly stop along the line protect CAN communication mining intrinsic safety type crashstop closedown switch.It is in intrinsic safety type housing, and one group of normally opened contact electrical connection of CAN communication circuit plate and microswitch, the side of slide block and the actuating strut Elastic Contact of microswitch, the opposite side of slide block contacts with latch buttons.When skid; pushing microswitch makes the normally opened contact of microswitch close to CAN communication circuit plate trigger pip; after microprocessor processes; current site information is sent to high-speed CAN transceiver module, and current site information is sent to peripheral protective device by CAN by high-speed CAN transceiver module.
Description
Technical field
The utility model relates to a kind of mining intrinsic safety type crashstop closedown switch utilizing CAN communication.Adopt CAN communication technology to replace 8421 yards and 485 communications, realize Coal Transportation and suddenly stop protection along the line.
Background technology
At present, information transmission is carried out in the conventional many employings of mining intrinsic safety type crashstop closedown switch 8421 yards or 485 communications.Adopt 8421 yards of urgency of carrying out transmitting close down lock-switch realize website quantity few, required cable is many and wiring complicated.The urgency adopting 485 communications to carry out transmitting lock-switch of closing down can only conduct interviews to each slave station in the mode of main website poll, and the real-time of system, poor reliability, communication distance is short, does not have fault tolerant mechanism.
Summary of the invention
In order to solve the short problem of existing mining intrinsic safety type crashstop closedown switch wiring complexity, poor real, poor reliability and communication distance, the utility model provides a kind of CAN communication mining intrinsic safety type crashstop closedown switch, and this mining intrinsic safety type crashstop closedown switch wiring is simple, real-time, reliability is high, communication distance is long.
The utility model solves the technical scheme that its technical matters adopts: in intrinsic safety type housing, one group of normally opened contact electrical connection of CAN communication circuit plate and microswitch, the side of slide block and the actuating strut Elastic Contact of microswitch, the opposite side of slide block contacts with latch buttons.When skid, pushing microswitch makes the normally opened contact of microswitch close to CAN communication circuit plate trigger pip, microprocessor is sent in the light-coupled isolation of trigger pip on CAN communication circuit plate, toggle switch is used for arranging current site information, microprocessor is to after the trigger pip process gathered, current site information is sent by high-speed CAN transceiver module, and communication speed reaches as high as 1Mbps, and communication distance is 10km farthest.CAN communication circuit plate is connected on protective device by CAN, and realize along the line parking and also show fault website on the protection device, staff can carry out problem inquiry and eliminating according to website display.When work is complete, rotation is pulled open latch buttons and can be resetted, and makes equipment control loop recover normal.
The beneficial effects of the utility model are, can show fault website accurately in real time, and wiring is simple, and communication distance is 10km farthest.

Embodiment
In FIG, one group of normally opened contact electrical connection of CAN communication circuit plate (2) and microswitch (3), the side of slide block (4) and the actuating strut Elastic Contact of microswitch (3), the opposite side of slide block (4) contacts with latch buttons (5).The wire rope (7) of housing (1) both sides is connected with slide block (4) by connector (9).Spring (8) is enclosed within wire rope (7), is between slide block (4) and housing (1) inwall.Pull wire rope (7), slide block (4) is to a Slideslip and extrude the spring (8) of homonymy, when the actuating strut of slide block (4) pushing microswitch (3), microswitch (3) action also gives CAN communication circuit plate (2) trigger pips, and signal lamp (6) lights simultaneously.Latch buttons (5) is pulled open in rotation can make slide block (4) reset, lock release, and synchronous signal pilot lamp (6) extinguishes.
In the embodiment depicted in figure 2, to CAN communication circuit plate (2) for direct current, after isolated from power reduction voltage circuit (11) step-down, give microprocessor (14) power supply.Trigger pip sends into microprocessor (14) through optocoupler (13) isolation; toggle switch (15) is used for arranging current site information; trigger pip sends microprocessor (14) to by signal input part (12); after microprocessor (14) process; current site information is sent to high-speed CAN transceiver module (16), and current site information is sent to peripheral protective device (17) by CAN by high-speed CAN transceiver module (16).
Claims (5)
1. a CAN communication mining intrinsic safety type crashstop closedown switch, there is intrinsic safety type housing, it is characterized in that: one group of normally opened contact electrical connection of CAN communication circuit plate and microswitch, the side of slide block and the actuating strut Elastic Contact of microswitch, the opposite side of slide block contacts with latch buttons.
