The beneficial effects of the utility model are: vehicle electric power system hit exception monitoring device of the present utility model comprises indication loop and current supply circuit, indicate back route indicator and relay the first contact in series, current supply circuit comprises the self-locking circuit that relay coil and the second contact serial connection thereof form, whether Control vehicle electric power system gives bulb powered, thereby it is abnormal by the bright of bulb or the indication vehicle that goes out, whether power supply hit to occur, the utility model has been realized on-site measurement does not need professional oscp and external source, only use the measurement of the simple and fast that the power supply of vehicle self just can complete.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of vehicle electric power system hit exception monitoring device of the present utility model;
Fig. 2 is the circuit diagram of vehicle electric power system hit exception monitoring device of the present utility model while entering monitoring state.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
The embodiment of a kind of electric power system hit exception monitoring device of the present utility model
As shown in Figure 1, electric power system hit exception monitoring device of the present utility model comprises indication loop and current supply circuit, indicate back route indicator and relay the first contact in series, current supply circuit comprises the self-locking circuit that relay coil and the second contact serial connection thereof form, after indication loop and current supply circuit parallel connection, electric power system to be measured is accessed in one end, other end ground connection, described current supply circuit repeat circuit the second two ends, contact are also connected to trigger switch, the first contact of relay is normally closed contact, the second contact is open contact, the indicating device here can adopt bulb, the annunciator of diode or other luminous class, also can adopt the voice guards such as buzzer phone, when electric power system VCC to be measured connects, bulb is lighted, when vehicle electric power system VCC disconnects, bulb extinguishes, relay is for controlling switching on and off between bulb and electric power system to be measured, trigger switch is used for making native system to enter monitoring state from initial condition.
The working process of electric power system hit exception monitoring device of the present utility model is as follows: when this monitoring device installs in initial condition in electric power system to be measured, trigger switch is in off-state, the coil of relay is not switched on, the normally closed contact of relay is connected, bulb and vehicle electric power system are connected, bulb is lighted, as shown in Figure 1; When this monitoring device need to carry out hit exception monitoring to electric power system, closure is trigger switch 1 once, now relay coil energising, its open contact adhesive, normally closed contact disconnects, and now bulb and electric power system disconnect, and bulb extinguishes, then break trigger switch, although trigger switch disconnects, relay coil still with electric power system in on-state, its normally closed contact is still in off-state, bulb still extinguishes, as shown in Figure 2.When electric power system is because certain fault causes moment to disconnect and moment adhesive abnormal, in this abnormal generating process, moment is when disconnect, coil moment of relay loses power supply, open contact disconnects, normally closed contact adhesive, bulb and vehicle electric power system are connected, and now do not light, this monitoring device returns to shown in Fig. 1, after moment adhesive, bulb is lit, when vehicle electric power system a kind of in stabilized conditions, there is not hit when abnormal, monitoring device is always in monitoring state, and as shown in Figure 2, bulb extinguishes always.
The embodiment of a kind of vehicle of the present utility model
As shown in Figure 1, vehicle of the present utility model comprises electric power system and electric power system hit exception monitoring device, electric power system hit exception monitoring device comprises indication loop and current supply circuit, indicate back route indicator and relay the first contact in series, current supply circuit comprises the self-locking circuit that relay coil and the second contact serial connection thereof form, access vehicle electric power system to be measured in one end after indication loop and current supply circuit parallel connection, other end ground connection, described current supply circuit repeat circuit the second two ends, contact are also connected to trigger switch, the first contact of relay is normally closed contact, the second contact is open contact, the indicating device here can adopt bulb, the annunciator of diode or other luminous class, also can adopt the voice guards such as buzzer phone, when vehicle electric power system VCC connects, bulb is lighted, when vehicle electric power system VCC disconnects, bulb extinguishes, relay is for controlling switching on and off between bulb and vehicle electric power system, trigger switch is used for making native system to enter monitoring state from initial condition.Its principle of work and process had been described in detail in last embodiment, no longer repeated here.
Therefore can to judge by the light on and off state of bulb whether the electric power system of vehicle hit occurred abnormal for monitoring device of the present utility model, and this device volume is little, low in energy consumption, structure order is firm, can be arranged in parallel by bike any electrical equipment side, the overall transient fault of monitor vehicle electric power system or local transient fault flexibly, can monitor accurately hit that concrete adaptor union mechanical connection causes or specifically the power supply input of certain module is abnormal, bring great convenience to quick judgement and the execute-in-place of vehicle electric power system hit fault.
