The specific embodiment

Below in conjunction with accompanying drawing the exploder that the utlity model has the battery status demonstration is further described:

Among Fig. 1, dc source 100, test signal input circuit 101, current-limiting resistance 102, light emitting diode display circuit 103 are formed the blasting network test circuit, its effect is to detect blasting network impedance situation before the bursting work for convenience, satisfy the regulation of " before each bursting work, the fireman must do the inspection of electric explosion network impedance " in " safety regulations in coal mine ".Dc source 100, voltage comparator circuit 201, under-voltage display circuit 202 formed the battery status display circuits, and its effect is to reduce to setting voltage value when following when cell voltage, makes tangible demonstration, more renews battery with the prompting user.Dc source 100, transistor DC converter 301, voltage doubling rectifing circuit 302, accumulator 303, controlling circuit of voltage regulation 304, display circuit 305, delay switching circuit 306, residual voltage leadage circuit 307 are formed the exploder circuit, its effect is the effect by foregoing circuit, the DC voltage (6V) of battery is risen to 1000 to 3000 volts (quantity according to the exploder detonating primer is different and different), be stored in the electric capacity, receive after the signal of blowing out, the electric energy that stores is sent in the discharge time of regulation.

Among Fig. 2, transistor BG1, resistance R 1, R2, capacitor C 1, high frequency oscillation converter T forms transistor DC converter 301 jointly, capacitor C 2, C3, diode D1, D2, D3, D4, form voltage doubling rectifing circuit 302, electrolytic capacitor C4, C5, C6, C7 forms accumulator 303, resistance R 3, R4, adjustable resistance W1, electrolytic capacitor C8, transistor BG2 and relay K J form controlling circuit of voltage regulation 304, resistance R 5, light emitting diode D5 forms display circuit 305, K switch 2 is formed delay switching circuit 306, bleeder resistance R11 forms residual voltage leadage circuit 307, resistance R 6 is formed current-limiting resistance 102, light emitting diode D6 forms light emitting diode display circuit 103, diode D7, electrolytic capacitor C9, resistance R 7, R8, R9, transistor BG3 forms voltage comparator circuit 201, resistance R 10, capacitor C 10, transistor BG4, light emitting diode D8 forms under-voltage display circuit 202.

Among Fig. 2, after K switch 1 closure, power supply and circuit are connected, and battery voltage signal enters voltage comparator circuit 201 through diode D7, electrochemical capacitor C9.Through preestablishing, when cell voltage was higher than setting value, triode BG3 ended voltage comparator circuit 201 by resistance R 7, R8, R9, transistor BG3, and triode BG4 does not end because of there being base current.Light emitting diode D8 because of BG4 by can not be luminous.When cell voltage less than when setting value, triode BG3 conducting, triode BG4 is because of obtaining the base current conducting, voltage is that light emitting diode is lighted after the R10 current limliting, reminds user's cell voltage to be lower than setting value, for normal use, battery should have been changed.The resistance that changes resistance R 7 can be set the height of the voltage that needs control easily.

Triode BG1, resistance R 1, R2, capacitor C 1, the transistor DC converter that high frequency oscillation transformer T forms must be established beginning work by cable because of K switch J-1 closure, with the conversion of the 6V voltage of dc source through this DC converter, the secondary square wave alternating-current voltage that produces at the high frequency oscillation transformer, this voltage is through capacitor C 2, C3, diode D1, D2, D3, the voltage doubling rectifing circuit that D4 forms is to storage capacitor C4, C5, C6, C7 charges, resistance R 3, R4, electrolytic capacitor C8, transistor BG2, with relay J K, the controlling circuit of voltage regulation of forming is connected to energy storage electrochemical capacitor C4, C5, C6, C7 "+;-" between the utmost point, it is to be noted that resistance R 3 is one group of resistance, its objective is the height of selecting the definite electrolytic capacitor group charging voltage that will control.When electrolytic capacitor group institute charging voltage reaches the voltage that will control, the voltage that comes out through resistance R 4 dividing potential drops makes triode BG2 conducting, the relay K J that is connected to the transistor collector loop has two groups of contacts, normally-closed contact KJ-1 and normally opened contact KJ-2, normally-closed contact KJ-1 is connected to the base loop of triode BG1, and normally opened contact KJ-2 is connected between display circuit and the positive source.When relay got electronic the work because of triode BG2 conducting, the normally-closed contact that is connected to triode BG1 base loop disconnected, and made triode lose base current and stopped concussion.The normally opened contact KJ-2 that is connected to display circuit and positive source connects, and makes display circuit get electroluminescent diode D5 and lights, and the expression charging is full, can blow out.Because the existence of electrochemical capacitor internal resistance, when external circuit no longer charges to the electrolytic capacitor group, the former electric energy that is stored in the electrolytic capacitor will reduce.When being lower than certain value, triode BG2 ends because of base voltage reduces, relay K J outage, and normally-closed contact KJ-1 closure, normally opened contact KJ-2 disconnects, and triode BG1 base stage is established the beginning concussion again by cable, light emitting diode D5 dead electricity and extinguishing.So go round and begin again, the charging voltage of electrolytic capacitor group just obtains control.
