Description
Technical Field
The invention belongs to the field of monitoring of electric propulsion ship storage batteries, and particularly relates to a high-reliability ship storage battery voltage detection system and a detection method thereof.
Background
Vessels employing electric propulsion devices as the primary power source are typically loaded with a large number of batteries, as compared to conventional power vessels. The electric propulsion ship storage battery is characterized in that: the number of the storage batteries is large, and can reach hundreds; (2) The reliability of the storage battery state monitoring requirement is high, and damage caused by overdriving and overdischarging of the storage battery is prevented; (3) The accumulator is usually located at the bottom of the cabin, the maintenance space is extremely narrow and harmful gases are present.
The existing storage battery state monitoring system sends state information such as voltage, temperature and the like of each storage battery to the storage battery inspection device through a communication cable by a storage battery state detection device arranged on each storage battery monomer. It has the following disadvantages: (1) The total amount of the storage battery is large, the storage battery cabin is in a high-temperature and high-humidity environment for a long time, and part of storage battery state detection sensors of a storage battery monitoring system are often damaged; (2) A single storage battery is matched with a voltage detection sensor of the storage battery, and if the internal circuit of the storage battery state detection device is damaged, the state of the single storage battery cannot be measured; (3) The storage battery state detection sensor is difficult to replace and maintain in time after being damaged; (4) If the measurement of the storage battery state detection sensor has errors, the storage battery state monitoring system cannot judge and cannot correct the measurement.
For the reasons, a shipman often needs to enter the storage battery cabin to maintain the storage battery state detection sensor in the storage battery monitoring system in a narrow space, so that the labor intensity of the shipman is greatly improved.
For the above reasons, it is therefore necessary to design a battery condition monitoring system with high reliability.
Disclosure of Invention
In order to solve the problems existing in the existing storage battery state monitoring system, one of the purposes of the invention is to provide a high-reliability ship storage battery voltage detection system.
The technical scheme adopted for solving the technical problems is as follows: a high-reliability ship storage battery voltage detection system is used for detecting storage battery monomers arranged in multiple rows, and comprises a detection probe connected with each storage battery monomer, wherein each storage battery monomer is provided with one detection probe, and a storage battery voltage sensor arranged between two adjacent storage battery monomers.
The second object of the present invention is to provide a method for detecting a voltage of a marine storage battery with high reliability, comprising the steps of: let the voltage of the reference voltage source be U s The voltage difference between each row of adjacent two battery cells detected by the battery voltage sensor is DeltaU, and the voltage difference between a single battery cell and the adjacent battery cells in the left row and the right row is DeltaU a And DeltaU b If the voltage of a certain battery cell detected by the battery voltage sensor is U m =0 or U m ＝U s +△U+△U a Or U m =0 or U m ＝U s +△U+△U b And judging that the storage battery monomer has faults.
The beneficial effects of the invention are as follows: compared with the existing high-reliability storage battery voltage detection system, the high-reliability storage battery voltage detection system has the advantages that the voltage of each storage battery can be detected by different paths at the same time, and after a single storage battery voltage sensor fails, the high-reliability storage battery voltage detection system can detect the state of the storage battery by other paths, so that the high-reliability storage battery voltage detection system has higher reliability, reduces the times of maintenance and replacement of the storage battery voltage sensor for a shipman, and lightens the labor intensity of the shipman.

Detailed Description
In order to better understand the rotation speed control potentiometer device of the ship propulsion motor provided by the invention for those skilled in the art, the control potentiometer device is clearly and completely described below with reference to the embodiment and the embodiment drawings of the invention. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art without the inventive effort, shall fall within the scope of the present invention.
Example 1
Referring to fig. 1, the high-reliability ship battery voltage detection system disclosed by the invention is used for detecting multiple rows of arranged battery cells 4, and comprises a detection probe 5 connected with each battery cell 4, wherein each battery cell 4 is provided with one detection probe 5, and a battery voltage sensor 3 arranged between two adjacent battery cells 4, each battery voltage sensor 3 is connected with the detection probes 5 on the two adjacent battery cells 4 through a wire so as to measure the voltage difference of the two battery cells 4, namely, one row of battery voltage sensors 3 is arranged between the two adjacent battery cells 4, one end of each battery voltage sensor 3 of the first row of battery cells 4 is connected with a standard reference voltage source 2, one end of each battery voltage sensor 3 of the last row of battery cells 4 is connected with a reference ground 6, and the battery voltage sensor 3 is connected with a voltage monitoring device 1 through a wired or wireless network so as to send the voltage result of a battery through a battery communication network.
The detection result of the battery voltage sensor 3 is sent to the battery voltage monitoring device 1 through a communication network to calculate and display the voltage of each single battery. The voltage of one battery cell 4 is calculated by referring to the algebraic sum of the voltage differences detected by all the battery voltage sensors 3 between the power source 2 and the battery cell 4 and it is judged whether or not there is a fault.
Example 2
The invention discloses a detection method of a storage battery voltage detection system, which comprises the following steps: let the voltage of the reference voltage source 2 be U s The voltage difference between each row of adjacent two battery cells 4 detected by the battery voltage sensor 3 is DeltaU, and the voltage difference between a single battery cell 4 and the adjacent battery cells 4 in the left and right rows is DeltaU a And DeltaU b If the voltage of a certain battery cell 4 detected by the battery voltage sensor 3 is U m =0 or U m ＝U s +△U+△U a Or U m =0 or U m ＝U s +△U+△U b Then, it is determined that the battery cell 4 has a failure.
As shown in fig. 2, if it is necessary to measure the voltage U of the battery cell 4 denoted as a m Can be derived from a reference power supply U s Starting from the path 7, the path 8 and the path 9, respectively, and from the reference point 6 the path 10 is followed by calculating the algebraic sum of the potential differences measured by the voltage sensors on the path to obtain the voltage of the battery cell 4 denoted a. Taking path 8 as an example, U m ＝U s +△U 11 +△U 12 +△U a +△U 22 Therefore, when the battery voltage sensor 3 on a certain path, for example, deltaU 12 In the event of a failure, the battery voltage monitoring device 1 can still calculate the voltage U of the battery cell 4, which is designated a, via the further paths 7, 9 and 10 m 。
The detection method of the invention has the principle that: if a certain battery cell 4 fails, the voltage value sent by the battery voltage sensor 3 to the battery voltage monitoring device 1 is always 0 or the normal voltage of a single battery cell 4, rather than the difference value of two battery voltages, so that the battery cell 4 with the failure is easily found, and the found data can be switched to another path for continuous monitoring after no data is found.
The detection system of the present invention thus has a higher reliability than the existing battery voltage monitoring device 1.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the invention. Various modifications or additions to the described embodiments may be made by those skilled in the art to which the invention pertains or may be substituted in a similar manner without departing from the spirit of the invention or beyond the scope of the appended claims.
