Description
Technical field
The present invention relates to power high voltage switch cabinet temperature to monitor field on-line.
Background technology
Dependence more and more higher of the modern society to electric power, the especially high area of electricity consumption density, for example, factory, shopping centre,
Large-scale capital construction etc..Electricity is have left, the life of people will sink into complete confusion, therefore requirement of the modern power systems to the quality of power supply
More and more higher, increasing requirement is correspondingly it is also proposed to electrical equipment, while the reliability of high-tension switch cabinet is also carried
Higher requirement is gone out.With the development of power network and updating for equipment, 10kV and 35kV high-tension switch cabinet are big
Amount use, and inside switch cabinet overheat the problem of turn into switch cubicle use during it is common the problem of, switch cubicle heating excessively will
Cause switch cubicle job failure or even trigger serious accident.The over-heat inside problem of switch cubicle is the mistake of a long term accumulation
Journey [34], if can find early, adopts an effective measure rapidly, will can greatly enhance insulating properties and to the extension of equipment life
It is very helpful.
Now, the switch cubicle used inside electric power, it is necessary to strictly observe the purchasing procedure technical indicator of equipment, ensure to network
Switch cubicle by type approval test, typically in the process of running electric load not over the design capacity of switch cubicle, switch cubicle
Temperature rise situation also will not be too prominent, but be also not all in actual applications so, current trolley type switch cabinet it is easy because
Switch cubicle causes switch cubicle to generate heat manufacturing, transport and install the problem of reason such as bad triggers contact resistance excessive.
The narrow space of high-tension switch cabinet, and once there is exposed high pressure interior, very strong electromagnetic interference be present, it is traditional
Temp measuring method can not all realize high-tension switch cabinet thermometric.Passive and wireless temperature monitoring system is that temperature sensor is installed into switch
On live contact in cabinet, real-time online measuring mother's board temperature, overtemperature alarm.
Device for detecting temperature is a very important part in passive and wireless temperature monitoring system, existing temperature monitoring dress
Device for detecting temperature can only be taken out by manually reaching high-tension switch cabinet scene from high-tension switch cabinet secondary chamber by putting software upgrading,
Restored to the original state again after provision for disengagement write-in program, one device for detecting temperature of installation in a high-tension switch cabinet, a general change
There is individual high-tension switch cabinet more than 30 in power station, completing the software upgrading of all device for detecting temperature will take a substantial amount of time and people
Power, and easily produce potential safety hazard in continuous dismounting and power down power up.
The content of the invention
It is a primary object of the present invention to provide a kind of on-line software updating method of device for detecting temperature, in Control Room
RS485 buses one end is that can be achieved to carry out software upgrading to the device for detecting temperature being serially connected in bus, is pressed off under removing to height
Cabinet scene dismounting terminal, electric cumbersome in power down is closed, while eliminates various unsafe factors.
In view of the shortcomings of the prior art, the present invention proposes that following technical scheme solves, and comprises the following steps：A kind of temperature prison
The on-line software updating method of device is surveyed, it comprises the following steps：
Step 1）, the ARM of device for detecting temperature carried into Flash be divided into bootloader program areas, application program
Area, backup application area and liquid crystal character library area；
Step 2）, device for detecting temperature software systems start, perform bootloader programs, if in 5s time window
It is intraoral to receive upgrade command, jump to step 3）, otherwise jump to step 4）；
Step 3）, by Xmodem FTPs receive file, if receive upgrade applications instruction,
Flash application areas are write, put application area flag bit, while copy to backup application area, put back-up application journey
Sequence distinctive emblem position, device for detecting temperature soft reboot, jumps to step 2）；If receiving the character library instruction of upgrading liquid crystal, write
Flash liquid crystal character libraries area, device for detecting temperature soft reboot, jumps to step 2）；
Step 4）, check the flag bit in application area and backup application area, if consistent and effectively, jump to
Step 5）If flag bit that is inconsistent and having a region is effective, by the data duplication of flag bit effective coverage to mark
The invalid region in position, if invalid, jumps to step 2）；
Step 5）, check whether application area is empty, if sky, then jump to step 2）, otherwise perform and apply journey
Sequence, in application program implementation procedure, if receiving instruction of restarting, device for detecting temperature soft reboot, jump to step 2）, otherwise should
Continued executing with program.
According to above-mentioned technical proposal as can be seen that advantages of the present invention is as follows：
It is simple to operate：It is that all temperature monitorings to being serially connected in bus can be achieved in RS485 buses one end of Control Room
Device carries out software upgrading, electric to high-tension switch cabinet scene dismounting terminal, in power down cumbersome under removing from, while weakens various
Unsafe factor；
High efficiency：General hundreds of K of liquid crystal character library, carrying out upgrading to liquid crystal character library by RS485 serial ports needs to expend largely
Time, and actually liquid crystal character library is very stable, general not have to upgrading, therefore application program and liquid crystal character library are upgraded respectively,
Both update time is shortened, and does not influence calling of the application program to liquid crystal character library；
High reliability：Transmit file using Xmodem FTPs, the agreement have good overtime retransmission mechanism and
Checking feature, it is ensured that the success rate and accuracy of file transmission；
High stability：Flag bit is put in application area and backup application area respectively, and is examined before application program performs
Survey the two flag bits, ensure device for detecting temperature once writing an application program, device for detecting temperature is at any time all
Newest application program can be performed.

Step 3）In 202, file is received by Xmodem FTPs, referred to if receiving upgrade applications
Order, then Flash application areas are write, put application area flag bit, while copy to backup application area, part of purchasing
Application area flag bit, device for detecting temperature soft reboot, jumps to step 2）201；If receive upgrading liquid crystal character library to refer to
Order, then write Flash liquid crystal character libraries area.Device for detecting temperature soft reboot, jumps to step 2）201；
Step 4）In 203, the flag bit in application area and backup application area is checked, if consistent and effective,
Jump to step 5）204, if flag bit that is inconsistent and having a region is effective, the data of flag bit effective coverage are answered
The invalid region of flag bit is made, if invalid, jumps to step 2）201；
Step 5）In 204, check whether application area is empty, if sky, then jumps to step 2）201, otherwise hold
Row application program, in application program implementation procedure, if receiving instruction of restarting, device for detecting temperature soft reboot, jump to step
2）201, otherwise application program continue executing with.
