Abstract
The invention provides a switch node temperature monitoring system of a distribution room, and belongs to the technical field of equipment detection and management in electric power industry. The system consists of a console and a detection device which is mounted in a distribution cabinet; a detection module in the detection device is connected to temperature probes under each distribution switch contact by virtue of a multi-mode optical fiber, wherein the main control chip central processing unit (CPU) of the detection module is a 8-bit singlechip; the CPU controls a circular scanning unit to detect the temperature of each distribution switch contact through an information collecting unit, and stores monitoring data into an information storage unit; and the CPU detects console instructions received by a signal transmitting and receiving unit at any time, and transmits the monitoring information of the information storage unit to the console through a signal modulation unit. The switch node temperature monitoring system of the distribution room provided by the invention has the beneficial effects that the good insulation characteristic of the multi-mode optical fiber and the convenience of wireless signal transmission and detection are combined, the manufacture cost is reduced by adopting the modular design of detection units, and the system can run more reliably and is more convenient to popularize and apply.
Description
Technical field
The invention belongs to power industry Equipment Inspection administrative skill field.
Background technology
In large-scale switchgear building, the dozens of power distribution cabinet is arranged usually, the panel switches that have quantity not wait again in each power distribution cabinet, only if certain switch breaks down, the operator on duty can not be checked through each switch under the normal condition.And the main cause that causes switch fault to be the switch contact loose contact make that node temperature rises, to a certain degree will burn out switch contact when temperature is elevated to, light power interruption then, heavy then cause bigger loss.Therefore, under normal situation on duty, grasp the variation of panel switches contact temperature at any time, just can prevent trouble before it happens, avoid the generation of this type of fault.And to solve the temperature of monitoring all panel switches nodes in a plurality of power distribution cabinets at any time, be necessary to develop targetedly a kind of checkout equipment.
Summary of the invention
The objective of the invention is to utilize panel switches contact temperature detection in wireless receiving instruction the carrying out power distribution cabinet, store.
Technical scheme of the present invention is: native system is made up of control desk and the pick-up unit that is installed in the power distribution cabinet; Pick-up unit is connected to the temp probe under each panel switches contact by a detection module through multimode optical fiber; The CPU Control Circulation scanning element of detection module detects each panel switches contact temperature through information acquisition unit, and Monitoring Data is stored into information memory cell; CPU detection at any time signal sends the console instruction that receiving element receives, and the monitoring information of information memory cell is sent it back control desk through the signal modulating unit; Also be provided with the address setting unit in the detection module.
Beneficial effect of the present invention: the present invention's insulation characterisitic that multimode optical fiber is good combines with the convenience of wireless transmission detection signal, adopts the detecting unit modular design to make cost of manufacture reduce, and moves more reliably, is more convenient for applying.
Description of drawings
Accompanying drawing 1 is circuit block diagram of the present invention.
Embodiment
Pick-up unit is made up of through the temp probe 3 that multimode optical fiber 2 is connected under each panel switches 4 contact a detection module 1.Detection module 1 has an external antenna interface and at least 32 optical fiber interfaces, and this apparatus main body can be fixed on the power distribution cabinet inwall.Each panel switches is close to the contact temperature probe 3 is installed, and is connected to the optical fiber interface of detection module 1 successively according to Position Number through multimode optical fiber 2.
The main control chip CPU of detection module 1 is 8 single-chip microcomputers, and CPU Control Circulation scanning element detects each panel switches 4 contact temperature through information acquisition unit successively, and Monitoring Data is stored into information memory cell; CPU detection at any time signal sends the console instruction that receiving element receives, and the monitoring information of information memory cell is sent it back control desk through the signal modulating unit.
Also be provided with the address setting unit in the detection module 1, before installation, unify numbering, make each panel switches of each power distribution cabinet that a unique encoding address all arranged.
Control desk is located at duty room, sends the temperature information that detects instruction and receive these panel switches through wireless channel, is aggregated into the computer Control Software and compares, and observes the real time data of the contact temperature of each panel switches 4 at any time.
The present invention's insulation characterisitic that multimode optical fiber is good combines with the convenience of wireless transmission detection signal, adopts the detecting unit modular design to make cost of manufacture reduce, and moves more reliably, is more convenient for applying.
