Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated: present embodiment provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment being to implement under the prerequisite with technical scheme of the present invention.
Embodiment:
Referring to Fig. 1; Intelligence thunderbolt monitoring device; It comprises Single-chip Controlling unit module (hereinafter to be referred as MCU); SPD remote signalling monitoring means module (hereinafter to be referred as RS), temperature detecting unit module (TS), thunderbolt detecting unit module (hereinafter to be referred as LT) and RS485 communication unit module (hereinafter to be referred as RS485) are formed.Wherein RS (Fig. 3) comprises capacitive device C16, C17, C18 and C19.TS comprises temperature sensor U10.LT (Fig. 2) comprises pressure limiting device RV1, filter capacitor C1, rectifying device BG1, signal amplifier spare Q1, current-limiting resistance R12, R13, R15, bypass biasing resistor R14 and filter capacitor C9, C10.RS485 (Fig. 5) comprises U1, pull-up resistor R1, R5, and pull down resistor R2, R3, R4, isolation resistance R6, R7, R8, pressure limiting diode D1, D2, D3, D4, and prevented that voltage device TVS1, TVS2, TVS3 and GAS1, GAS2, GAS3 formed.
TS is the digital real time device, and single-chip microcomputer is constantly monitored U10, when occurring limiting the requirement variation, will change requiring signal to be transferred to the RS485 module, the detection main frame is carried out Information Monitoring send.Single-chip microcomputer plays a part to detect lightning protection device remote signalling fault simultaneously; When lightning protection device remote signalling fault; Capacitive device C16, C17, C18 and the C19 of RS module will receive the influence of remote signalling fault, produce charge and discharge phenomena, when monolithic detects this phenomenon; Just can produce the remote signalling fault-signal, send to detecting main frame through the RS485 module.When lightning current passed through lightning protection device, the LT module will produce induction to the big electric current of releasing, and RV1 carries out pressure limiting through the pressure limiting device; And the clutter in the signal carried out filtering through C1, and after the BG1 rectification, the impact that module just can the various lightning currents of self-adaptation; And the influence of not receiving lightning current direction polarity; Signal after the rectification amplifies through Q1 through the further filtration of R12, R13 and C5, becomes the discernible signal of single-chip microcomputer; Supply single-chip microcomputer to judge, single-chip microcomputer is reported the monitoring main frame through the RS485 module after with signal Processing.

The monitor software control requires---the temperature control part branch
Product serviceability temperature :-40 ℃～120 ℃
Need the product of detected temperatures to be divided into:
1P、2P、3P、4P
Be under the normal condition, 1 voltage dependent resistor (VDR) of minimum detection detects 4 voltage dependent resistor (VDR)s at most,
If do not detect temperature sensor, then the closing temperature test item only provides the environment temperature test.
Temperature detection, during normality:
The curve map of voltage dependent resistor (VDR) temperature and power is as shown in Figure 6.
The fault alarm prompting:
If must " fault " report to the police so the voltage dependent resistor (VDR) surface temperature surpasses 120 degrees centigrade, otherwise can make the SPD damage.Temperature sampling cycle 0.5s.
When surface during at 80～120 degrees centigrade; If detect this switching value action (switching value is opened by normally closed often becoming) this moment; Then point out SPD " inefficacy " (changing immediately) alarm, if detect the switching value attonity, when temperature still surpasses 80 degrees centigrade behind the 5min; Prompting SPD " fault " alarm, and the preventative misfire fault of prompting SPD.
More than show and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the instructions just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
