Abstract
The invention discloses a temperature monitoring device for multi-contact temperature measurement. The temperature monitoring device is characterized in that a plurality of contacts are adopted and used for transmitting the acquired temperature information to a communication module; the communication module transmits converted digital signals to a state indicating instrument; and the signals in the state indicating instrument are converted by a communication manager and transmitted to a host computer. By adopting the structure, the monitoring device has the following advantages: 1, the plurality of contacts are adopted and used for measuring the temperature, and a high-voltage cabinet is monitored in an omnibearing way; 2, the serial communication is carried out, thus the online monitoring function is realized; 3, the temperature sensing is stable and reliable, and error display and reporting hardly occur; and 4, elements lower in price are adopted, so that the producing cost is relatively low.
Description
Technical field
The present invention relates to the temperature monitoring in the high-tension switch cabinet, particularly a kind of device for detecting temperature for the multiple contact thermometric.
Background technology
High-tension switch cabinet is in During Process of Long-term Operation, and part component thermal power can be very large, easily causes local pyrexia serious, can cause serious fault after developing into certain phase, destroys the safe and reliable of power supply.And the long-term humidity of the regional air at part switch cubicle place is serious or temperature contrast is larger sooner or later, and switch cubicle moves under this environment, and components and parts can be affected, and easily cause the generation of short circuit or shelf depreciation accident.In recent years, overheat accident, the shelf depreciation accident of a lot of switch cubicles occured in generating plant and transformer station, causes fire and large-area power failure.Be the generation of preapring for an unfavorable turn of events in advance, controller switching equipment and transmission line of electricity cause major accident because of problems of excessive heat.
It is the problem that prior art need to solve that temperature in the high-voltage board is carried out comprehensively accurate on-line monitoring.
Summary of the invention
Technical matters to be solved by this invention is, a kind of device for detecting temperature for the multiple contact thermometric is provided, and the temperature in the high-voltage board is carried out comprehensively accurate on-line monitoring is the problem that prior art need to solve to reach.
For solving the problems of the technologies described above, technical scheme of the present invention is, a kind of device for detecting temperature for the multiple contact thermometric, it is characterized in that: described monitoring device is that a plurality of contacts are delivered to communication module with the temperature information that collects, digital signal transfers after communication module will be changed is to state indicator, signal in the state indicator is by the communication manager conversion and flow to host computer, thereby has realized carrying out the function of multipoint temperature monitoring in the high-voltage board.
Described communication module is arranged on the pcb board of state indicator, and the model of communication chip is RSM485CT in the communication module.
Communication between described contact, communication module, state indicator, communication manager, the host computer is RS485 interface and Modbus communications protocol.
Control signal and the control liquid crystal display of the collection output signal of described state indicator while receiving key amount and illumination, heating, air draft show.
The model of the processor of described state indicator is STC12C5A60AD.
A kind of device for detecting temperature for the multiple contact thermometric, owing to adopting said structure, this monitoring device has the following advantages: 1, multichannel contact temperature measurement, carry out omnibearing monitoring to high-voltage board; 2, serial communication has the function of on-line monitoring; 3, temperature sense is reliable and stable, is difficult for the aobvious wrong report of mistake; 4, use the lower components and parts of price, production cost is lower.

In Fig. 1,1, state indicator; 2, contact; 3, communication module; 4, communication manager; 5, host computer.
Embodiment
As shown in Figure 1, the present invention is that a plurality of contacts 2 are delivered to communication module 3 with the temperature information that collects, digital signal transfers after communication module 3 will be changed is to state indicator 1, signal in the state indicator 1 is by communication manager 4 conversions and flow to host computer 5, thereby has realized carrying out the function of multipoint temperature monitoring in the high-voltage board.
Control signal and the control liquid crystal display of the collection output signal of 1 while of state indicator receiving key amount and illumination, heating, air draft show.And the model of the processor of state indicator 1 is STC12C5A60AD.
As shown in Figure 2, increased a pair of communication terminal TTA/485B1 and TTB/485A1 at state indicator 1 at back terminal place, increased communication module U4 at mainboard, guaranteed that thermometric data can transmit to advance in the state indicator 1.
The specific works process is as follows: when airborne temperature is A ℃, sensed by contact 2, contact 2 obtains a thermal signal, be transferred in the state indicator 1 by the RS485 interface, signal is transferred to chip by communication module 3 conversions on state indicator 1 mainboard, through the analysis conversion of chip STC12C5A60AD, be delivered on the liquid crystal display, it is A ℃ that the control liquid crystal display is read concrete temperature.Signal transfers to host computer 5 by communication manager 4 again, is convenient to background monitoring.
The present invention satisfies most customer demand by the multichannel contact temperature measurement, utilizes serial communication so that the temperature data transmission is more accurate, and the simultaneous temperature induction is reliable and stable, can not show wrong report by mistake.
The above has carried out exemplary description to the present invention by reference to the accompanying drawings; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted technical solution of the present invention to carry out, or directly apply to other occasion without improvement, all within protection scope of the present invention.
