Specific embodiment
In being described below, for illustration and not for limitation, the tool of such as particular system structure, technology etc is proposed
Body details, to understand thoroughly the utility model embodiment.However, it will be clear to one skilled in the art that there is no these
The utility model also may be implemented in the other embodiments of detail.In other situations, omit to well-known system,
The detailed description of apparatus, circuit and method, in case unnecessary details interferes the description of the utility model.
In order to illustrate technical solution described in the utility model, the following is a description of specific embodiments.
It as depicted in figs. 1 and 2, is a kind of Generator Slip Ring temperature monitoring system provided by the embodiment of the utility model, packet
It includes: data sink 1, monitor terminal 2, and the temperature sensing being arranged on the carbon brush seat board 4 of 3 side of testing generator slip ring
The temp probe 9 of device 5, controller 6 and data transmission blocks 7, the temperature sensor 5 is close to 3 side of testing generator slip ring
8 surface of carbon brush, the temperature sensor 5 connects the controller 6, and the controller 6 connects the data transmission blocks 7,
The data transmission blocks 7 wirelessly connect the data sink 1, and the data sink 1 connects the monitoring
Terminal 2.
Specifically, fixed temperature sensor 5, controller 6 and data transmission blocks 7 on the carbon brush seat board 4 of isolation material,
Ensure temperature sensor 5 in addition to measured carbon brush, any other metal open circuit of getting along well, the temp probe 9 of temperature sensor 5 is close to
Carbon brush surface, since measurement position is close to carbon brush and slip ring contact surface, so the temperature value measured is closer to actual temperature value.
Since temperature rise is a slowly varying process, so carry out intermittent measurement can satisfy the mesh being monitored to temperature completely
, temperature measurement time interval is rationally set, it is preferred that temperature sensor 5 measured the temperature data of a carbon brush every 60 seconds,
After controller 6 receives temperature data, data transmission blocks 7 are sent to, data transmission blocks 7 are wirelessly sent to number
According to receiver 1, data sink 1 is shown temperature data is sent to monitor terminal, is checked for operator.By slip ring
While there is multiple groups carbon brush, every group of carbon brush is mounted on the same carbon brush seat board, and carbon brush seat board is mounted on beside slip ring, so each
Multiple temperature sensors are installed on carbon brush seat board, multiple temperature sensors connect a controller, meanwhile, the measurement of intermittent
