Consult Fig. 1-2, the block scheme of the failure detector 100 of the electrical equipment 200 that present pre-ferred embodiments provides.Described failure detector 100 is connected with described electrical equipment 200, and described electrical equipment 200 comprises air switch 201 and load 202, and the input end of described air switch 201 is connected with external power source 300.
Electrical equipment 200 both can be watch-dog (as camera, monitor etc.) also can be other power equipment (as electric light, transformer etc.).Electrical equipment 200 comprises air switch 201 and load 202.Wherein air switch 201 is for protecting load 202, and when the situations such as short circuit, heavy overload or under-voltage appear in the circuit be connected with load 202, air switch 201 trips, and cuts off the connection of load 202 and external power source 300.Wherein, external power source 300 can be the commercial power interface of 220V, also can be other power supply facilitiess.
Described failure detector 100 and the port of other equipment connections comprise the first input test side 101, second and input test side 102, the 3rd and input test side 104 and output detections end 103.Described first input test side 101 connects the input end of described air switch 201, described second input test side 102 connects the output terminal of described air switch 201, described 3rd input test side 104 is connected with outside uninterrupted power source 400, and described output detections end 103 connects the input end of described load 202.Failure detector 100 also comprises: the first voltage detection module 111, second voltage detection module 112, load 202 detection module 113, tertiary voltage detection module 114, Temperature and Humidity module 115 and breakdown judge module 116.In the present embodiment, above-mentioned each detection module can be the circuit unit for realizing specific function be combined to form by one or more electron device, also can be the chip with specific function.Below each functional module that described failure detector 100 comprises is described in detail.
First voltage detection module 111, for detecting described first input test side 101 first detects voltage.
Second voltage detection module 112, for detecting described second input test side 102 second detects voltage.
First the magnitude of voltage at air switch 201 two ends is detected respectively.The input end of air switch 201 is connected with external power source 300.Under normal condition, detect at the first input test side 101 place of the input end connecting air switch 201 first detects voltage, should be identical with the output voltage of external power source 300.And air switch 201 itself is almost do not have resistance, when air switch 201 is normal, detect in the second input test side second detects voltage also should with first to detect voltage identical.If electrical equipment 200 breaks down, first detect voltage and second detect voltage may appear as 0 situation.For the commercial power interface that external power source 300 is 220V, the first detection voltage and second detects voltage and divides other testing result may have two kinds, 220V and 0.Namely the testing result that the first detection voltage and the second detection combinations of voltages get up has multiple, the different malfunction of electrical equipment 200 that difference is corresponding.

Such as, when first detect voltage be described external power source 300 output voltage values, second detect voltage be 0 time, failure judgement state is that air switch 201 trips.
Second detection voltage is 0, illustrate after air switch 201, the loss of voltage in circuit, namely occurred the state of open circuit, and first detects the output voltage values that voltage is described external power source 300, add and understand that the position that open circuit occurs is exactly at air switch 201 place.The function of air switch 201 is when the situations such as short circuit, heavy overload and under-voltage appear in the circuit be connected with load 202, trips, and cuts off the connection of load 202 and external power source 300.Therefore, when first detect voltage be described external power source 300 output voltage values, second detect voltage be 0 time, cause the out-of-work reason of electrical equipment 200 to be that air switch 201 trips.
When the first detection voltage is 0, failure judgement state is that external power source 300 has a power failure.
The input end of air switch 201 does not detect voltage, just illustrates that problem has appearred in the output of external power source 300.Therefore, when the first detection voltage is 0, the out-of-work reason of electrical equipment 200 is caused to be that external power source 300 has a power failure.
In this enforcement, also some special situations are considered, as when second detect voltage be as described in external power source 300 output voltage values, first detect voltage be 0 time, illustrate that electrical equipment 200 does not break down, the reason causing above-mentioned situation to occur is the loose contact of the second input test side 102 and electrical equipment 200.First detection voltage is 0, illustrate to input between test side 102 from external power source 300 to the second and occurred that open circuit or external power source 300 have a power failure, and the output voltage values that the second detection voltage is described external power source 300 illustrates that external power source 300 is normal, but the first detection voltage is 0, what outlet open circuit was described is between the second input test side 102 and electrical equipment 200, i.e. the loose contact of the second input test side 102 electrical equipment 200.
