Description

1 The invention relates to the field of electrical engineering, in particular to the field of combined secondary power sources. A power supply device is known that contains a galvanic power source and a measuring circuit for controlling the voltage of a galvanic source. However, this device-Evo is characterized by insufficient use of the life span of galvanic sources due to the fact that the meter on the circuit measures the voltage on the galvanic source at currents significantly different from the load current of the power supply unit. Closest to the invention is a semiautomatic test bench for chemical testing of current sources, which contains a programming unit, a switching unit, a load equivalent unit, a measuring unit, and a C 21 signaling unit. The known device does not provide real-time accuracy in the presence of interference. the formation of the result of the control of the galvanic source; The aim of the invention is to increase the reliability of the analysis of the voltage level of the galvanic source. The goal is achieved by the fact that a periodic galvanic source control device containing a start-up unit, a pulse generator, a key element whose input is intended to be connected to a galvanic source code, and an output is connected through a load equivalent unit to the threshold element, and a threshold fixation unit the element, the element OR is entered, and the fixation unit of the triggering of the threshold element is cotoit from a trigger and a differentiating circuit, and the input of the differentiating circuit is connected to the input of the element, the output of the threshold element with the trigger information input, the first input of the OR element is connected to the start unit, the second input is connected to the output of the pulse generator, and the output of the OR element is connected to the control input of the key element and the trigger input of the trigger 35 The pulses are connected to the inverse of the trigger input, the setup input of which is connected to the output of the differentiating circuit, and the direct output of the trigger is the signal output of the device. The drawing shows an block diagram of the device. The block diagram shows the power supply source 1, galvanic source 2, interface 3, start-up block 4, element OR 5, key element 6, load equivalent 7, threshold element 8, block 9 of triggering the trigger element, the load bus 11, the signal output of the control device 12, the trigger 13, and the differentiating circuit 14. In the presence of mains voltage, the external consumer is connected to the bus 11 by the voltage of the source 1 supplied to the bus 11 via the interface 3, When fail x failures n the mains supply voltage of the external consumer is provided from the galvanic source 2, the voltage of which is supplied to the bus 11 through the interface 3 to the bus 11. Due to the diode isolation to the node 3 of the interface of the source 1 and the galvanic source 2, the bus 11 is powered by only one of the indicated sources. To do this, it is necessary to ensure that the operating voltage of source 1 exceeds the possible maximum value of the voltage of the galvanic source 2, the command generated by the start-up unit 4 and entering the control input of the key element 6, analyzes the voltage level of the galvanic source 2. At the same time The action of the command key element 6 is unlocked on the control input and the galvanic source 2 is loaded with a load equivalent to the consumer connected to the bus 11. The threshold element 8 performs an analysis of the voltage level of the galvanic source 2 loaded on the load equivalent. If the voltage level of the galvanic source 2, measured at the load equivalent 7, is below the maximum permissible level, then at the output of the threshold

element 8, a single logic level is formed, indicating that the voltage of the galvanic source is. ka 2 is not normal.

On the falling edge of the start command, the analysis result is written to the memory element — the trigger 13 of the actuation block 9 of the threshold element 8,

Due to the connection of the trigger 13 with the control input of the pulse generator 10, the generated signal controls the operation of the pulse generator 10

In the case of recording in the fixation unit of the triggering of the threshold element of the 15 sign, the voltage of the galvanic source 2 is not normal, the corresponding pulse signal at the inverse output of the trigger 13 unlocks the pulse generator 10, generating an infra-low non-core pulse sequence inputted through the OR 5 element to the control input the key element 6 and the clock input of the trigger 13. Each of the pulses performs the role of a start command, similar to the start command generated by the start block 4. At each of the pulses, the key element 6 is unlocked, and the threshold element 8 measures the voltage level of the galvanic source 2 at the load equivalent 7. At the falling front of the corresponding pulse, the result of the analysis is recorded in the fixing unit of the triggering of the threshold element.

Thus, if the sign n

electroplating source; not normally generated due to an accidental disturbance, the next pulse of the generator 10 performs a repeated analysis process ypt on the voltage of the galvanic source 2 and, if it is normal, returns the state of the memory element of the trigger 13 to the normal state (

By selecting the appropriate transfer equivalent load equivalent 7 and / or threshold of the threshold element 8 (carried out once, when mounting the device), you can select the appropriate advance-reserve energy source galvanic source 2, which allows the operator to get some time (for example, a day, several days) to replace the source on duty. When the operator installs a new galvanic source 2 at the output of the differentiating circuit 14, a pulse arises that resets the trigger to the initial normal state. The use of the proposed offset allows the maximum use of the energy capacity of the galvanic source, combined with the automatic generation of the sign of the failure of this source.
