Detailed description of the invention
Fig. 1 is the temperature sensor location schematic diagram in the present invention.
Fig. 2 is closed loop feedback adjustment schematic diagram of the present invention.
In figure: 1- protective relaying device；2-DSP chip；3- temperature sensor.
Specific embodiment
Technical solution of the present invention is described in further detail below in conjunction with Figure of description.
As shown in Figs. 1-2, a kind of temperature monitoring method of site installation protective relaying device, comprising the following steps:
Step 1: the environment temperature T inside acquisition protective relaying device 1enviWith the work temperature of dsp chip 2chip；
Step 2: the environment temperature T of 1 pair of protective relaying device acquisitionenviAnd/or the work temperature of dsp chip 2chipWhether
Operating temperature range in bound is judged；
Step 3: being more than operating temperature range, then protective relaying device 1 is sent a warning message；
Step 4: protective relaying device 1, which carries out closed loop feedback adjustment according to temperature information and warning information, realizes work
Adjusting and optimizing send to port temperature and temperature warning information to reduce temperature.
For the ease of real-time temperature collection data, environment temperature environment temperature TenviWith the work temperature of dsp chip 2chip
It is acquired by the way that temperature sensor 3 is arranged on 1 inside of protective relaying device and dsp chip 2.It can by temperature sensor 3
With easily real-time temperature collection data.
