[0002] In an existing uninterruptible power supply system (UPS) of a power distribution room, the main function of the UPS is to provide temporary power supply when the main power supply fails. The state of the battery group directly affects whether the UPS can provide stable power at the critical moment, so the detection of the battery group is very important.

[0035] Embodiment 1

[0036] Reference Figure 1 , Figure 1 is a structural schematic block diagram of a detection distribution circuit provided by an embodiment of the present application.

[0037] The detection distribution circuit is used in an uninterrupted power supply system of a power distribution room, and the uninterrupted power supply system includes a battery group composed of a plurality of batteries, and each battery of the battery group is provided with a sensor. The detection distribution circuit includes:

[0038] a timing signal distribution module, the timing signal distribution module includes N output ends, the activation of each output end is mutually exclusive, and N is an integer not less than 4.

[0039] a detector module, 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 a 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, a control end of an nth relay is connected with an nth output end of the timing signal distribution module; the nth relay further includes a plurality of groups of normally open contacts, one end of any group of normally open contacts is connected with the sensor, and the other end is connected with 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 to enable the signal input end of the detection chip to be electrically connected with the sensor through the nth relay; n is a positive integer not greater than N. The nth relay is any one of the first relay to the Nth relay.

[0041] The timing signal distribution module is responsible for controlling the timing of the detection process, and has at least four output terminals. The activation of the output terminals is mutually exclusive, that is, only one output terminal is activated at any time, which ensures the orderliness of the detection process. The detector module is composed of a detection chip and a display screen. The detection chip is responsible for receiving signals from the sensors and displaying corresponding sensor data such as battery temperature, voltage, current, etc. on the display screen. The execution module includes N relays, each corresponding to an output terminal of the timing signal distribution module. Each relay has multiple normally open contacts, one end of which 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 contacts of the corresponding nth relay are closed, allowing the detection chip to electrically connect to each sensor through the relay, thereby reading the sensor data. It can be considered that the timing signal distribution module realizes the dot matrix control of the sensor model.

[0042] In a specific application, when the detection process starts, the timing signal distribution module activates the output terminals one by one in a predetermined order. When each output terminal is activated, the corresponding relay is closed, allowing the detection chip to 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 effects of the embodiment are that the mutual exclusion activation mechanism of the timing signal distribution module ensures the orderliness of the detection process. The display screen of the detector module can directly display the sensor data, making it easy 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 expandable. By monitoring the status of the battery pack in real time, abnormal conditions of the battery can be detected in a timely manner, avoiding safety hazards caused by battery failure. By using one detector module and multiple relays, the number of detectors required is reduced, enabling point cycle detection and reducing hardware costs. Since the number of detector modules is reduced, the required space is also reduced, 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 and the frequency input terminal of the first distribution chip are connected to transmit the clock signal; the output terminal of the first distribution chip and the frequency input terminal of the second distribution chip are connected to make the N output terminals of the second distribution chip activated one by one.

[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. According to the control of its N output terminals, the sequential detection of each battery sensor in the battery group is realized. Specifically, the N output terminals of the second distribution chip can be activated individually in a period of not less than 3 seconds and not more than 10 seconds.

[0046] The beneficial effects of the embodiment are that through the cascade of the clock unit and the two distribution chips, the timing control of precise and optional time intervals can be realized, ensuring that each battery sensor can be detected at the correct time. Sequential detection makes it easier for maintenance personnel to locate problem batteries, as each activation corresponds to the action of a relay, and the detection of each relay corresponding to a group of batteries is independent.

[0047] In an exemplary embodiment, the signal locking end of the second distribution chip and the locking output end of the detection chip are electrically connected, for receiving the locking signal output by the detection chip and locking the activation state of the currently activated output terminal.

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

[0049] The beneficial effects of the embodiment are that the locking mechanism allows the system to quickly lock the state when an abnormal situation is detected, facilitating subsequent fault diagnosis and handling.

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

[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 end of the detection chip. When a certain output terminal of the second distribution chip is activated, the corresponding relay closes its normally open contacts, allowing the signal input end of the detection chip to be electrically connected to the sensor, thereby reading the data of the sensor. The display screen is used to display the sensing data of each signal input end on the same screen or to scroll the sensing data of each signal input end.

[0052] In an exemplary embodiment, a first transistor is further included between the control terminal of the nth relay and the nth output terminal 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 terminal of the nth relay, and the base of the first transistor is connected to the nth output terminal 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 from 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 circuit between the collector and the emitter is turned on, thereby activating the relay.

[0054] The beneficial effect of this embodiment is that the first transistor is used as an intermediate switch, simplifying the circuit design from the timing signal distribution module to the relay, reducing the complexity of the circuit.

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

[0056] The base of the fourth transistor is used to input a second reset signal, the emitter of the fourth transistor is grounded and connected to the reset terminal 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 the use of transistors as reset switches can simplify circuit design, reduce the number of components required, and reduce the complexity of the circuit. The fast switching characteristics of the transistor improve the response speed, making the reset operation more rapid, thereby reducing the recovery time.

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

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

[0064] In an exemplary embodiment, the detection distribution device further comprises a warning device, the warning device being connected to a detection chip of a detector module of the detection distribution device and used for receiving a warning signal sent by the detection chip.

[0065] As an example, a detection distribution device for an uninterrupted power supply system in a power distribution room is provided. The uninterrupted power supply system comprises a battery group composed of a plurality of batteries, and each battery of the battery group is provided with a temperature sensor. The detection distribution device comprises a detection distribution circuit and a warning device, and the detection distribution circuit comprises a timing signal distribution module, a detector module and an execution module.

[0066] Referring to Figure 2 and Figure 3 , Figure 2 is a circuit schematic diagram of a clock unit and a first distribution chip provided by the embodiment of the present application. Figure 3 is a circuit schematic diagram of a second distribution chip provided by the embodiment of the present application.

[0067] The timing signal distribution module comprises a clock unit, a first distribution chip and a second distribution chip. The clock unit and a frequency input (CL) of the first distribution chip are connected to transmit a clock signal; an output of the first distribution chip and a frequency input of the second distribution chip are connected to make 8 output ends of the second distribution chip activated in turn and individually. The 8 output ends of the second distribution chip are output ends of the timing signal distribution module, and the activation of each output end is mutually exclusive.

[0068] The first distribution chip and the second distribution chip are CD4022, the first end to the sixteenth end of which are Q1, Q0, Q2, Q5, Q6, Nc, Q3, Vss, Nc, Q7, Q4, C0, CL.INH, CL, R, and VDD end, respectively. The first end to the fifth end, the seventh end, the tenth end, and the eleventh 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 fourteenth end of the first distribution chip. The fifteenth end of the first distribution chip is used for resetting by 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 fifteenth end of the first distribution chip, and the collector of the second transistor is connected to the power supply voltage VDD.

The sensing signals of the corresponding four sensors are transmitted to the detector module. The power supply voltage VDD in the application is, for example, DC 5V.

[0073] Embodiment 3

[0074] The embodiment provides a detection distribution method, which is applied to a detector module and uses the detection distribution device to realize battery cycle detection of each battery group. The specific implementation and the achieved technical effects are the same as those described in the system implementation, and part of the content will not be repeated.

[0075] Referring to Figure 5 , Figure 5 is a flowchart of a detection distribution method provided by the embodiment.

[0076] The method comprises:

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

[0078] S2, displaying the plurality of sensing data of the nth battery group, to realize cycle display of the sensing data of the N battery groups; N is an integer greater than or equal to 4, n is a positive integer less than or equal to N, and the preset order is a cycle order of n from 1 to N in size.

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

[0080] obtaining a data range of a sensing type corresponding to the sensing data; when at least one sensing data of the plurality of sensors of the nth battery group is not in the data range of the corresponding sensing type, generating a locking signal and sending it to a 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 sensing data of the plurality of sensors of the nth battery group is not in the data range of the corresponding sensing type, the method further comprises: generating an alarm signal and sending it to an alarm device, and using the alarm device to alarm the user of the detection abnormality.

[0082] First, the data of the plurality of sensors of the nth battery group is obtained. The sensors can monitor key parameters such as voltage, current, temperature, etc. The sensing data of each sensor is compared with its corresponding preset data range. The preset data range is set based on the sensor type and the normal operation condition of the battery group. If the sensing data of any sensor exceeds the preset data range, an abnormality is identified. Once an abnormality is detected, an alarm signal is generated. The alarm signal is then sent to an alarm device, such as a buzzer or an alarm light set on site. After receiving the alarm signal, the alarm device alarms the on-site personnel (user) through sound, light or other means, prompting that an abnormality is detected and needs to be paid attention to or actioned.

[0083] In a specific application, the method can be applied to a detector module, and the embodiment has the beneficial effect that, through timely warning, the safety risk caused by battery pack failure can be reduced, and the safety of personnel and equipment can be protected. Through accurate data range comparison, the possibility of false positives is reduced, and the accuracy of the warning is improved.

[0084] In an exemplary embodiment, when at least one sensor data of the plurality of sensors of the nth battery pack is not within the data range of its corresponding sensor type, a lock 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 sensor data of the plurality of sensors of the nth battery pack is not within the data range of its corresponding sensor 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 lock 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 sensor data of the plurality of sensors of the nth battery pack is not within the data range of its corresponding sensor type, a warning signal is generated and sent to a warning device, and the warning device is used to warn the user of the detection anomaly, including:

[0088] When the timing information is greater than the second time threshold corresponding to the sensor data, the nth battery pack count value 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 pack is less than the second time threshold corresponding to the sensor data for two consecutive times, the nth battery pack count value is counted minus one until it is zero.

[0090] When the nth battery pack count value is greater than the count value threshold, a warning signal is generated and sent to a warning device, and the warning device is used to warn the user of the detection anomaly; an alarm information is generated and sent to a user device of a management personnel. 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 (for example, 3 seconds, 5 seconds or 7 seconds), a lock signal is generated and sent to the time 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 a preset second time threshold (a value less than the first time threshold, for example, 2 seconds, 3 seconds or 4 seconds) but does not reach the first time threshold, the count value of the third battery group is incremented by one. If the timing information of the third battery group is less than the second time threshold for two consecutive times, the count value of the third battery group is decremented by one until it reaches zero. When the count value of the third battery group exceeds a count value threshold (for example, 4), an alarm signal is generated and sent to an alarm device, such as a buzzer and an alarm light, to alert the user (on-site personnel) of the detection of an 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 effects of the embodiment are that if the on-site personnel manually reset the second distribution chip when the output terminal of the second distribution chip is locked due to abnormal sensing data, the problem is not really solved. In this case, through the timing and threshold judgment mechanism, the abnormal change of the sensor data can be quickly responded to, and timely locking and alarming can be achieved. By setting two different time thresholds, temporary fluctuations and real abnormal situations can be distinguished, reducing false positives. Through intuitive alarm devices such as buzzers and alarm lights, the user (on-site personnel) can quickly detect abnormal situations, improving the efficiency of the alarm. At the same time, the alarm message is sent to the user device of the management personnel, so that the management personnel can timely understand the situation even if they are 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" means one or more, and "multiple" means two or more. The "and / or" describes the association relationship between the associated objects, which means that there can be three kinds of relationships, for example, A and / or B, which can represent the existence of A alone, the existence of A and B together, and the existence of B alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the front and rear associated objects. "At least one of the following" or similar expressions means any combination of these items, including any combination of single item or multiple items. For example, at least one of a, b or c can represent a, b, c, a and b, a and c, b and c, or a and b and c, where a, b and c can be single or multiple.
