Description
Technical field
The utility model relates to a kind of Domestic distributing box with parameter display, belongs to an electro-technical field.
Background technology
The distribution box that family uses can by the power supply in each room of family separately; separately by the power supply of various function simultaneously; such as powerful air-conditioning, electric consumption on lighting and with electrical socket etc., and arrange air switch, can protect overcurrent, under-voltage and electric leakage like this.But such distribution box can not allow user understand electricity consumption situation in each supply line, be unfavorable for when there is tripping operation, the root that tracing trouble occurs.
Summary of the invention
The purpose of this utility model is to overcome weak point of the prior art, a kind of Domestic distributing box with parameter display is provided, the program detects the electric parameter on each current supply circuit of distribution box, and show, user not only can be allowed intuitively to understand electricity consumption situation, also help under there are abnormal conditions and carry out failure diagnosis.
The utility model solves the technical scheme that its technical problem adopts:
There is the Domestic distributing box of parameter display; comprise the housing playing accommodation and protective effect; described housing is arranged at least one air switch; can cut off the electricity supply under under-voltage or overcurrent condition; arrange electronic-controlled installation in described housing, described electronic-controlled installation comprises power module, and described power module is for generation of the voltage be applicable to; use to other modules, also comprise:
---carry out central controlled processor, be responsible for parameter detecting and interface display;
---the display module be connected with described processor, can show electric current, voltage and temperature parameter;
---the flow measurement circuit be connected with described processor, for detecting the size of current by described air switch;
---the pressure measurement circuit be connected with described processor, for detecting the voltage swing of the air switch described in input;
---the temperature measurement circuit be connected with described processor, for detecting the temperature height of described enclosure interior.
The beneficial effects of the utility model are mainly manifested in: can detect the electric parameter on each current supply circuit of distribution box, such as electric current, voltage and temperature, and by these parameter displays out, be conducive to user and intuitively understand electricity consumption situation, and carry out failure diagnosis under being conducive to that abnormal conditions occur.
Accompanying drawing explanation
Fig. 1 is the outside drawing of the Domestic distributing box with parameter display;
Fig. 2 is the control principle drawing of the Domestic distributing box with parameter display;
The theory diagram of Fig. 3 voltage sampling circuit.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
With reference to Fig. 1-3; there is the Domestic distributing box of parameter display, comprise the housing 8 playing accommodation and protective effect, described housing is arranged at least one air switch 7; described air switch 7 can be cut off the electricity supply under under-voltage or overcurrent condition, thus avoids having an accident.Arrange electronic-controlled installation in described housing 8, described electronic-controlled installation comprises power module 2, and described power module 2, for generation of the voltage be applicable to, uses to other modules, also comprises:
---carry out central controlled processor 1, be responsible for the detection of electric current, voltage and temperature, and by these parameter displays out.Described processor 1 internal setting data memory, preserves the supplemental characteristic in a period of time, when tripping, for analysis of failure source provides analysis data, can adopt the AVR series monolithic of atmel corp.
---the display module 3 be connected with described processor 1, described display module 3 is set to LCD display, or light-emitting diode display, can show the temperature of input voltage and described housing 8 inside, and the size of current of each current supply circuit.
---be connected flow measurement circuit 5 with described processor 1, for detecting the size of current by described air switch 7.In order to detect current value, described flow measurement circuit 5 arranges current transformer and signal processing circuit, described current transformer is arranged on the current supply circuit of described air switch 7, convert alternating current value to magnitude of voltage, described signal processing circuit is carried out amplitude amplification and is exported to described processor 1, calculates and obtain current value after the 1 pair of magnitude of voltage sampling of described processor; Described signal processing circuit can adopt common scaling circuit, and arranges filter capacitor and remove some interference signals.
---be connected pressure measurement circuit 4 with described processor 1, for detecting the voltage swing of the air switch 7 described in input.The power input of the Domestic distributing box described in input connection of described pressure measurement circuit 5, is connected to described processor 1 after input voltage is carried out dividing potential drop, carries out calculating the magnitude of voltage obtaining input after described processor 1 detects.As shown in Figure 3, resistance R1 connects power input, the processor 1 described in resistance R1 is connected with resistance R2 dividing potential drop later, and resistance R2 two ends parallel diode D1, in input voltage negative half-cycle, diode D1 can by the voltage clamping on resistance R2 at-0.7V.
---be connected temperature measurement circuit 6 with described processor 1, for detecting the temperature height of described enclosure interior.Described temperature measurement circuit 6 adopts thermistor temperature detecting, and thermistor changes resistance by variations in temperature, thus affects circuit parameter, such as voltage, the impulse electricity time etc., and described processor 1 detects this Parameters variation and carries out accounting temperature value.
In sum, the utility model provides a kind of Domestic distributing box with parameter display, the program detects the electric parameter on each current supply circuit of distribution box, and show, comprise voltage, electric current and temperature, these information can allow user intuitively understand the electricity consumption situation of family, and when tripping, can be analyzing failure cause and providing analysis data.
