It should be understood that the preferred embodiments are only for illustrating the present application, not for limiting the scope of protection of the present application.

[0035] Example 1

[0036] See also Figure 1 , Figure 1 It is a structural schematic block diagram of a detection distribution circuit provided in an embodiment of the present application.

[0037] The detection distribution circuit is used for an uninterruptible power supply system in a power distribution room. The uninterruptible power supply system includes a battery group consisting of a plurality of batteries. A sensor is provided on the battery of each battery group. The detection distribution circuit includes:

[0038] A timing signal distribution module, wherein the timing signal distribution module comprises N output terminals, activation of each of the output terminals is mutually exclusive, and N is an integer not less than 4.

[0039] The detector module includes a detection chip and a display screen. The detection chip is used to display corresponding sensing data on the display screen according to the sensing signal of the sensor; the sensing data is, for example, temperature data, current data, etc.

[0040] An execution module, the execution module includes N relays, the control end of the nth relay is connected to the nth output end of the timing signal distribution module; the nth relay also includes multiple groups of normally open contacts, one end of any group of normally open contacts is connected to the sensor, and the other end is connected to a signal input end of the detection chip of the detector module; when the nth output end of the timing signal distribution module is activated, the normally open contact is closed so that the signal input end of the detection chip is electrically connected to the sensor through the nth relay; n is a positive integer not greater than N. The nth relay is any one of the 1st to Nth relays.

[0041] The timing signal distribution module is responsible for controlling the timing of the detection process and has at least 4 output terminals. The activation of the output terminals is mutually exclusive, that is, only one output terminal is activated at any time, which can ensure the orderliness of the detection process. The detector module consists of a detection chip and a display screen. The detection chip is responsible for receiving signals from the sensor and displaying the corresponding sensor data on the display screen according to these signals, such as the temperature, voltage, current and other parameters of the battery. The execution module contains N relays, each of which corresponds to an output terminal of the timing signal distribution module. Each relay has multiple normally open contacts, one end of the normally open contact is connected to the sensor, and the other end is connected to the signal input terminal of the detection chip. When the nth output terminal of the timing signal distribution module is activated, the normally open contact of the corresponding nth relay is closed, so that the detection chip can be electrically connected to the sensor corresponding to each normally open contact through the relay, thereby reading the data of the sensor. It can be considered that the timing signal distribution module realizes the dot matrix control of the sensor model.

[0042] In specific applications, when the detection process starts, the timing signal distribution module activates the output terminals one by one in a preset order. When each output terminal is activated, the corresponding relay is closed, so that the detection chip can read the data of multiple sensors connected to the relay. The timing signal distribution module activates the next output terminal, and the relay corresponding to the next output terminal is closed to read the data of the next group of sensors. The above process is repeated.

[0043] The beneficial effect of this embodiment is that the orderliness of the detection process is ensured by the mutually exclusive activation mechanism of the timing signal distribution module. The display screen of the detector module can directly display the sensing data of the sensor, which is convenient for maintenance personnel to quickly understand the status of the battery pack and perform fault diagnosis and maintenance. Due to the modular design, the number of sensors and relays can be increased or decreased as needed, making the distribution circuit flexible and extensible. By real-time cyclic monitoring of the status of the battery pack, abnormal conditions of the battery can be discovered in time to avoid safety hazards caused by battery failures. By using a detector module and multiple relays, the number of detectors required is reduced, and point cycle detection can be achieved, thereby reducing hardware costs. Since the number of detector modules is reduced, the required space is also reduced accordingly, solving the problem of space congestion.

[0044] In an exemplary embodiment, the timing signal distribution module includes a clock unit, a first distribution chip and a second distribution chip; the clock unit is connected to the frequency input end of the first distribution chip for transmitting a clock signal; the output end of the first distribution chip is connected to the frequency input end of the second distribution chip for activating N output ends of the second distribution chip separately and in sequence.

[0045] The clock unit is responsible for generating a stable clock signal, which is the basis for subsequent signal distribution. The first distribution chip receives the clock signal from the clock unit, and the second distribution chip receives the output signal of the first distribution chip, and controls its N output terminals to achieve sequential detection of each battery sensor in the battery pack. Specifically, the N output terminals of the second distribution chip can be activated separately in sequence according to a period of not less than 3 seconds and not more than 10 seconds.

[0046] The beneficial effect of this embodiment is that, through the cascade connection of the clock unit and the two distribution chips, precise and selectable time interval timing control can be achieved to ensure that each battery sensor can be detected at the correct time. Sequential detection makes it easier for maintenance personnel to locate the problem battery, because each activation corresponds to the action of a relay, and the detection of a group of batteries corresponding to each relay is performed independently.

[0047] In an exemplary embodiment, the signal locking terminal of the second distribution chip is electrically connected to the locking output terminal of the detection chip, and is used to receive the locking signal output by the detection chip and lock the activation state of the currently activated output terminal.

[0048] After receiving the signal from the sensor, the detection chip will determine whether it is necessary to lock the current detection state according to the preset conditions. If necessary, the detection chip will send a lock signal through its lock output terminal. The signal lock terminal of the second distribution chip is used to receive the lock signal from the detection chip. When the lock signal is received, the second distribution chip will lock the activation state of the currently activated output terminal to ensure that the output terminal remains activated until the next valid unlock signal arrives, such as a reset signal.

[0049] The beneficial effect of this embodiment is that the locking mechanism allows the system to quickly lock the state when an abnormal situation is detected, which facilitates subsequent fault diagnosis and processing.

[0050] In an exemplary embodiment, the value of N is 6, and the nth relay includes 4 groups of normally open contacts, one end of each group of normally open contacts is connected to a sensor, and the other end is connected to a separate signal input terminal of the detection chip; the display screen is used to display the sensor data of each signal input terminal on the same screen, or to scroll and display the sensor data of each signal input terminal.

[0051] Each nth relay (n is a positive integer from 1 to 6) includes 4 groups of normally open contacts. One end of each group of normally open contacts is connected to a sensor, and the other end is connected to a separate signal input terminal of the detection chip. When a certain output terminal of the second distribution chip is activated, the corresponding relay closes its normally open contact, so that the signal input terminal of the detection chip is electrically connected to the sensor, thereby reading the data of the sensor. The display screen is used to display or scroll the sensor data of each signal input terminal on the same screen.

[0052] In an exemplary embodiment, a first transistor is further included between the control end of the nth relay and the nth output end of the timing signal distribution module, the emitter of the first transistor is grounded, the collector of the first transistor is connected to the control end of the nth relay, and the base of the first transistor is connected to the nth output end of the timing signal distribution module.

[0053] The first transistor is used as an electronic switch to control the activation of the relay. The emitter of the first transistor is grounded, the collector is connected to the control terminal of the nth relay, and the base is connected to the nth output terminal of the timing signal distribution module. The signal emitted by the nth output terminal of the timing signal distribution module is transmitted to the base of the first transistor. When the base of the first transistor receives the signal from the timing signal distribution module, the first transistor is turned on, and the collector and the emitter are connected, thereby activating the relay.

[0054] The beneficial effect of this embodiment is that the first transistor is used as the intermediate switch, which simplifies the circuit design directly from the timing signal distribution module to the relay and reduces the complexity of the circuit.

[0055] In an exemplary embodiment, the timing signal distribution module further includes a second triode and a fourth triode, the base of the second triode is used to access the first reset signal, the emitter of the second triode is grounded and connected to the reset end of the first distribution chip, and the collector of the second triode is connected to the power supply voltage;

[0056] The base of the fourth transistor is used to access the second reset signal, the emitter of the fourth transistor is grounded and connected to the reset end of the second distribution chip, and the collector of the fourth transistor is connected to the power supply voltage.

[0057] The second transistor is used to receive the first reset signal to reset or reset the state of the first distribution chip. After the second transistor is turned on, the circuit between its collector and emitter is closed, thereby triggering the reset process of the first distribution chip. After the first distribution chip is reset, its output can be reinitialized.

[0058] The fourth transistor is used to receive the second reset signal to reset or reset the state of the second distribution chip. When the base of the fourth transistor receives the signal, the circuit between the collector and the emitter is closed, triggering the reset process of the second distribution chip. After the second distribution chip is reset, its output can be reinitialized.

[0059] The beneficial effect of this embodiment is that using a transistor as a reset switch can simplify circuit design, reduce the number of components required, and reduce circuit complexity. The fast switching characteristics of the transistor increase the response speed, making the reset operation faster, thereby reducing the recovery time.

[0060] In an exemplary embodiment, the timing signal distribution module also includes a third transistor, the base of the third transistor is used to connect to the output end of the second distribution chip, the emitter of the third transistor is grounded and connected to the frequency input end of the second distribution chip, and the collector of the third transistor is connected to the power supply voltage.

[0061] In an exemplary embodiment, the models of the first distribution chip and the second distribution chip are CD4022, and the model of the relay is G6K-2F-Y.

[0063] An embodiment of the present application provides a detection distribution device for an uninterruptible power supply system in a power distribution room, wherein the detection distribution device includes the detection distribution circuit described in any one of Embodiment 1.

[0064] In an exemplary embodiment, a warning device is further included, and the warning device is connected to the detection chip of the detector module of the detection and distribution device, and is used to receive a warning signal sent by the detection chip.

[0065] As an example, a detection distribution device is provided for an uninterruptible power supply system in a power distribution room. The uninterruptible power supply system includes a battery pack consisting of a plurality of batteries, and a temperature sensor is provided on each battery pack. The detection distribution device includes a detection distribution circuit and a warning device, and the detection distribution circuit includes a timing signal distribution module, a detector module, and an execution module.

[0066] See also Figure 2 and Figure 3 , Figure 2 This is a circuit diagram of a clock unit and a first distribution chip provided in an embodiment of the present application. Figure 3 This is a circuit diagram of a second distribution chip provided in an embodiment of the present application.

[0067] The timing signal distribution module includes a clock unit, a first distribution chip and a second distribution chip. The clock unit is connected to the frequency input terminal (CL) of the first distribution chip for transmitting a clock signal; the output terminal of the first distribution chip is connected to the frequency input terminal of the second distribution chip for activating the eight output terminals of the second distribution chip in sequence. The eight output terminals of the second distribution chip serve as the output terminals of the timing signal distribution module, and the activation of each of the output terminals is mutually exclusive.

[0068] The first distribution chip and the second distribution chip are selected from the same CD4022, and the 1st to 16th ends thereof are Q1, Q0, Q2, Q5, Q6, Nc, Q3, Vss, Nc, Q7, Q4, C0, CL.INH, CL, R, and VDD ends respectively. The 1st to 5th ends, the 7th end, the 10th end, and the 11th end are output ends. The input end of the clock unit is connected to the power supply voltage VDD, and the output end is connected to the 14th end of the first distribution chip. The 15th end of the first distribution chip is used to reset through the first reset signal RT. Specifically, the first reset signal RT is connected to the base of the second transistor, the emitter of the second transistor is grounded and connected to the 15th end of the first distribution chip, and the collector of the second transistor is connected to the power supply voltage VDD.

[0069] The output signal Sin of the first distribution chip is connected to the base of the third transistor through a series diode and resistor. The emitter of the third transistor is grounded and connected to the 14th terminal of the second distribution chip. The collector of the third transistor is connected to the power supply voltage VDD.

[0070] The 15th terminal of the second distribution chip is used to reset by the second reset signal QR. Specifically, the second reset signal QR is connected to the base of the fourth transistor, the emitter of the fourth transistor is grounded and connected to the 15th terminal of the second distribution chip, and the collector of the fourth transistor is connected to the power supply voltage VDD.

[0071] The over-temperature lock (signal) is connected to the 13th terminal of the second distribution chip.

[0072] See also Figure 4 , Figure 4 It is a partial circuit diagram of an execution module provided in an embodiment of the present application. Take one of the relays for illustration. In actual application, there are multiple relays, preferably 6. The relay model is G6K-2F-Y, and the relay includes 4 groups of normally open contacts, namely T7-1, T6-1; T7-2, T6-2; T7-3, T6-3; T7-4, T6-4. One end of each group of normally open contacts is connected to a sensor, and the other end is connected to a signal input end of the detection chip. When the Q5 end of the second distribution chip is activated, one control end of the relay is grounded, and the other control end is connected to the power supply voltage VDD, so that the 4 groups of normally open contacts are closed. The corresponding sensing signals of the 4 sensors are transmitted to the detector module. The power supply voltage VDD in the present application is, for example, DC5V.

[0073] Example 3

[0074] This embodiment provides a detection allocation method, which uses the detection allocation device described in the second aspect to implement battery cycle detection of each battery pack. Its specific implementation method is consistent with the implementation method and technical effects recorded in the above system implementation method, and some contents are not repeated here.

[0075] See also Figure 5 , Figure 5 It is a flow chart of a detection allocation method provided in an embodiment of the present application.

[0076] The method comprises:

[0077] S1, obtaining sensing data of multiple sensors of the nth battery group through multiple groups of normally open contacts of the nth relay in a preset order;

[0078] S2, displaying multiple sensor data of the nth battery group, realizing cyclic display of sensor data of N battery groups; N is an integer not less than 4, n is a positive integer not greater than N, and the preset order is that the values ​​of n are cyclically sorted from 1 to N according to size. For example, the cyclic order is 1st, 2nd, 3rd, 4th, 1st, ...

[0079] In an exemplary embodiment, the method further comprises:

[0080] Acquire the data range of the sensor type corresponding to the sensor data; when at least one sensor data of the multiple sensors of the nth battery group is not within the data range of its corresponding sensor type, generate a locking signal and send it to the timing signal distribution module to lock the activation state of the currently activated output end of the timing signal distribution module.

[0081] In an exemplary embodiment, when at least one sensor data of multiple sensors of the nth battery group is not within the data range of its corresponding sensor type, the method further includes: generating a warning signal and sending it to a warning device, and using the warning device to warn the user of the detection abnormality.

[0082] First, obtain the data of multiple sensors of the nth battery pack. The sensors may monitor key parameters such as voltage, current, temperature, etc. Compare the sensing data of each sensor with its corresponding preset data range. The preset data range is set based on the sensor type and the conditions for normal operation of the battery pack. If the sensing data of any sensor exceeds the preset data range, identify the abnormality. Once the abnormality is detected, a warning signal is generated. The warning signal is then sent to a warning device, such as a buzzer or warning light set up on site. After receiving the warning signal, the warning device sends a warning to the on-site personnel (user) through sound, light or other means, indicating that an abnormality has been detected and attention or action is required.

[0083] In specific applications, the method can be applied to a detector module. The beneficial effect of this embodiment is that, through timely warnings, the safety risks caused by battery pack failures can be reduced, and the safety of personnel and equipment can be protected. Through accurate data range comparison, the possibility of false alarms is reduced and the accuracy of warnings is improved.

[0084] In an exemplary embodiment, when at least one sensing data of the multiple sensors of the nth battery group is not within the data range of the corresponding sensing type, a locking signal is generated and sent to the timing signal distribution module to lock the activation state of the currently activated output terminal of the timing signal distribution module, including:

[0085] When at least one of the sensing data of the multiple sensors of the nth battery group is not within the data range of the corresponding sensing type, timing is performed to obtain timing information;

[0086] When the timing information is greater than the first time threshold corresponding to the sensor data, a locking signal is generated and sent to the timing signal distribution module to lock the activation state of the currently activated output terminal of the timing signal distribution module. The first time threshold is, for example, 3 seconds, 5 seconds or 7 seconds.

[0087] When at least one of the sensing data of the multiple sensors of the nth battery group is obtained to be outside the data range of the corresponding sensing type, a warning signal is generated and sent to a warning device, and the warning device is used to warn a user of the abnormal detection, including:

[0088] When the timing information is greater than the second time threshold corresponding to the sensor data and less than the second time threshold, the count value of the nth battery pack corresponding to the sensor data is counted plus one; the value of the second time threshold is less than the first time threshold; the second time threshold is, for example, 2 seconds, 3 seconds or 4 seconds;

[0089] When the timing information of the nth battery group is less than the second time threshold corresponding to the sensor data for two consecutive times, the count value of the nth battery group is counted down to zero;

[0090] When the count value of the nth battery pack is greater than the count value threshold, a warning signal is generated and sent to the warning device, and the warning device is used to warn the user of the abnormal detection; an alarm message is generated and sent to the user device of the administrator. The warning device includes at least one of a buzzer and a warning light, and the user device includes at least one of a mobile phone and a tablet.

[0091] As an example, when the sensing data of any sensor of the third battery group exceeds its preset normal data range, a timer is started to obtain timing information. If the timing information exceeds a preset first time threshold (e.g., 3 seconds, 5 seconds, or 7 seconds), a locking signal is generated and sent to the timing signal distribution module to lock the activation state of the currently activated output terminal.

[0092] When the sensing data exceeds the normal range, if the timing information exceeds the preset second time threshold (the value is less than the first time threshold, such as 2 seconds, 3 seconds or 4 seconds) but does not reach the first time threshold, the count value of the third battery group is counted and added by one. If the timing information of the third battery group is less than the second time threshold twice in a row, the count value of the third battery group is reduced by one until it is reduced to zero. When the count value of the third battery group exceeds the count value threshold (for example, 4), a warning signal is generated and sent to a warning device, such as a buzzer and a warning light, to warn the user (on-site personnel) of the detection abnormality. At the same time, an alarm message is generated and sent to the user device of the management personnel, such as a mobile phone and a tablet.

[0093] The beneficial effect of this embodiment is that when the output end of the second distribution chip is locked due to sensor data at the distribution room, if the on-site personnel manually reset the second distribution chip, the problem is not really solved. In this case, through the timing and threshold judgment mechanism, it is possible to quickly respond to abnormal changes in sensor data, and lock and warn in time. By setting two different time thresholds, temporary fluctuations and real abnormal situations can be distinguished, reducing false alarms. Through intuitive warning devices such as buzzers and warning lights, users (on-site personnel) can quickly perceive abnormal situations, improving the efficiency of warnings. At the same time, the alarm information is sent to the user device of the manager, so that the manager can understand the situation in time even if he is not on site, improving the timeliness of handling abnormalities.

[0094] It should be noted that, in the embodiments of the present application, "at least one" refers to one or more, and "plurality" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.
