For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are also within the scope of the application. In addition, the embodiments of the present application and the features of the embodiments may be combined with each other without collision. The application will be described in detail below with reference to the drawings in connection with embodiments.

Fig. 1 is a schematic diagram showing an overall structure of a rights distribution system of a device according to an embodiment of the present application. As shown in fig. 1, the system includes: a master device 1, a transmission control unit 2, and a slave device 3;

The transmission control unit 2 is connected between the master device 1 and the slave device 3 through a first connection mode, the master device 1 and the slave device 3 are also directly connected through a second connection mode, and the first connection mode is different from the second connection mode;

The transmission control unit 2 comprises a first controllable switch unit 4, and the master device 1 is configured to send a first signal to the first controllable switch unit 4, where the first signal is configured to instruct the first controllable switch unit 4 to be turned on;

The slave device 3 is configured to receive a second signal when the first controllable switch unit 4 is turned on, where the second signal is used to instruct the slave device 3 to obtain rights from the master device 1, and obtain, according to the second signal, the assigned rights from the master device 1 through the second connection mode.

The working process of the authority distribution system of the equipment is as follows:

the master device 1 sends a first signal to the first controllable switching unit 4 in the transmission control unit 2 via the first connection, which signal indicates that the first controllable switching unit 4 is on. The first controllable switch unit 4 is turned on when receiving the first signal, and the first controllable switch unit 4 transmits the second signal to the slave device 3 through the first connection mode when being turned on. The slave device 3 receives a second signal indicating that the slave device 3 obtains rights from the master device 1 when the first controllable switch unit 4 is turned on, and obtains the assigned rights from the master device 1 through a second connection mode according to the second signal. The corresponding rights operation is performed after the assigned rights are acquired from the device 3.

Wherein the master device 1 may be a server or a control center for controlling the issuance of the associated rights allocation by the slave device 3. For example, the master device 1 may control the charging or discharging of the slave device 3 (e.g. an energy storage device), or the master device 1 may control the reporting of data by the slave device 3.

Optionally, after the slave device 3 obtains the assigned rights from the master device 1, the slave device 3 sends the information of the received assigned rights to the master device 1 through the second connection mode, and the master device 1 does not need to send the assigned rights to the slave device 3 any more.

According to the permission distribution system of the equipment, the master equipment 1 sends the first signal to the first controllable switch unit 4 in the first connection mode, the first controllable switch unit 4 is conducted when receiving the first signal and sends the second signal to the slave equipment 3, and the slave equipment 3 receives the second signal and acquires the distributed permission from the master equipment 1 in the second connection mode. According to the application, the slave device 3 is informed of the need of acquiring the assigned rights through the first controllable switch unit 4 by adopting one connection mode by the master device 1, and the slave device 3 directly acquires the assigned rights from the master device 1 by adopting another connection mode; according to the permission distribution system of the equipment, different paths for triggering the acquisition permission and directly acquiring the permission are realized through the combination mode of the master equipment 1, the transmission control unit 2 and the slave equipment 3 and different connection modes, the slave equipment 3 is informed of the permission to acquire distribution through the first controllable switch unit 4, and flexible controllability of signal transmission is improved.

The first connection mode is set to be an electrical connection, and the transmission control unit 2 is connected with the master device 1 and the slave device 3 through the electrical connection, and accordingly, the first signal and the second signal are electrical signals, for example, the first signal and the second signal may be voltage signals or current signals. By the above-described different connection means, information exchange can be performed stably and efficiently between the master device 1, the transmission control unit 2, and the slave device 3.

Optionally, as shown in fig. 2, the transmission control unit 2 further comprises a second controllable switch unit 5, the second controllable switch unit 5 being connected between the first controllable switch unit 4 and the slave device 3; the first controllable switch unit 4 is used for sending a third signal to the second controllable switch unit 5 when being conducted, and the third signal is used for indicating the second controllable switch unit 5 to be conducted; the second controllable switching unit 5 is arranged to send a second signal to the slave device 3 when turned on.

In this embodiment, the transmission control unit 2 includes a first controllable switch unit 4 and a second controllable switch unit 5, where the second controllable switch unit 5 is connected between the first controllable switch unit 4 and the slave device 3, and the first controllable switch unit 4 sends a third signal to the second controllable switch unit 5 when turned on, indicating that the second controllable switch unit 5 is turned on, and sends a second signal to the slave device 3 when the second controllable switch unit 5 is turned on.

Since the first signal, the second signal and the third signal are voltage signals, the second signal can be sent to the slave device 3 by mistake in isolation through the second controllable switch unit 5 in the transmission control unit 2. In the actual use process, the circuit may generate a voltage signal identical to the first signal, so that the first controllable switch unit 4 is turned on, and the first controllable switch unit 4 transmits a second signal which is the voltage signal to the slave device 3, so that the slave device 3 obtains the assigned authority to the master device 1. Therefore, the present application provides for the second controllable switching unit 5, even if the first controllable switching unit 4 is turned on, the first controllable switching unit 4 delivers less voltage of the voltage signal to the second controllable switching unit 5 in case of misleading, which is insufficient to render the second controllable switching unit 5 conductive, and thus does not cause the second controllable switching unit 5 to send the second signal to the slave device 3.

Optionally, the first controllable switch unit 4 comprises a triode, the base electrode of which is electrically connected with the master device 1, the emitter electrode of which is grounded, and the collector electrode of which is electrically connected with the slave device 3.

When the master device 1 needs to send the right of charging or discharging to the slave device 3, the master device 1 applies a positive voltage to the base electrode of the triode in the first controllable switch unit 4, the triode is turned on, the triode sends a certain voltage signal (namely a third signal) to the second controllable switch unit 5, the second controllable switch unit 5 is turned on, and then the second controllable switch unit 5 sends the second signal to the slave device 3, so that the purpose of triggering the slave device 3 to acquire the distribution right to the master device 1 is achieved.

In addition, by effectively electrically connecting and disconnecting the transistor in the first controllable switch unit 4, the stability and reliability of the system are improved.

Alternatively, as shown in fig. 3, the number of the slave devices 3 and the transmission control units 2 is plural, and the plural slave devices 3 are connected to the plural transmission control units 2 in one-to-one correspondence; the plurality of transmission control units 2 are sequentially and electrically connected, the first transmission control unit 2 which is sequentially and electrically connected is directly connected with the main equipment 1, and the last transmission control unit 2 is grounded; the last transmission control unit 2 is arranged to send a first signal to the next transmission control unit 2 after the acquisition of the assigned rights from the device 3.

In this embodiment, the slave devices 3 are taken as energy storage devices, where each slave device 3 is an energy storage device for storing electric energy, the master device 1 is used for controlling the charging or discharging rights of each slave device 3, and each slave device 3 needs to obtain the assigned rights to perform the charging and discharging operation. Each transmission control unit 2 is correspondingly connected to one slave device 3 and is used for sending a signal for acquiring the authority allocation to the slave device 3. The present embodiment is described taking as an example voltage signals transmitted between each other electrically connected.

Further, the first slave device 3 performs the charging or discharging operation after acquiring the assigned rights from the master device 1, and the first transmission control unit 2 sends a first voltage signal 5 to the next transmission control unit 2, indicating that the next slave device 3 may acquire the assigned rights from the master device 1, performing the charging or discharging operation after acquiring the assigned rights from the next slave device 3, and so on, and the subsequent operations are similar and will not be repeated here. After the last transmission control unit receives the first voltage signal from the last transmission control unit, the last transmission control unit sends a second voltage signal to the last slave device 3 connected with the last transmission control unit, after the last slave device acquires the assigned permission from the master device 1 and performs charging or discharging operation, the last transmission control unit 2 continues to send the first voltage signal backwards, but because the last transmission control unit 2 is grounded, the first voltage signal is transmitted to the grounding terminal, so that stable operation of the whole circuit is ensured.

According to the system, each slave device 3 performs charging or discharging operation according to the order of receiving the allocation rights, so that overload or other safety problems of the system can be avoided, and the charging or discharging efficiency and safety of the system are improved. The application allows the authorized slave device to perform charging or discharging operation, thereby increasing the security and the management flexibility of the system.

Optionally, as shown in fig. 4, the transmission control unit 2 further includes a third controllable switch unit 6, where the third controllable switch unit 6 and the first controllable switch unit 4 in the same transmission control unit 2 are connected in parallel between the master device 1 and the slave device 3; the third controllable switch unit 6 in the previous transmission control unit 2 is electrically connected with the first controllable switch unit 4 in the next transmission control system; a third controllable switching unit 6 for receiving a fourth signal sent from the device 3, the fourth signal indicating that the assigned rights are acquired from the device 3, and for sending a first signal to the first controllable switching unit 4 of the next transmission control unit 2.

After the first voltage signal 5 indicates that the first controllable switch unit 4 is turned on, the first controllable switch unit 4 in the first transmission control unit 2 sends a third voltage signal 8 to the second controllable switch unit 5, after the third voltage signal 8 enables the second controllable switch unit 5 to be turned on, the second controllable switch unit 5 sends a second voltage signal 6 to the slave device 3, the second voltage signal 6 indicates that the slave device 3 obtains an allocation right from the master device 1, after the first slave device 3 obtains the right allocated by the master device 1, a fourth signal is sent to the third controllable switch unit 6, the third controllable switch unit 6 is turned on, and because the third controllable switch unit 6 in the same transmission control unit 2 and the first controllable switch unit 4 are connected in parallel between the master device 1 and the first slave device 3, one end of the third controllable switch unit 9 is also electrically connected with the master device 1, the first voltage signal sent by the master device 1 also sends a third voltage signal to the third controllable switch unit 6, and then the third controllable switch unit 6 receives the third voltage signal from the first controllable switch unit 6 and the first controllable switch unit 6 in the same transmission control unit 2, and the third controllable switch unit 6 is turned on. Since the third controllable switch unit 6 and the first controllable switch unit 4 in the same transmission control unit 2 are connected in parallel between the previous transmission control unit 2 and the second slave device 3, one end of the third controllable switch unit 6 is also electrically connected with the third controllable switch unit 6 in the previous transmission control unit, the first voltage signal sent by the third controllable switch unit 6 from the previous transmission control unit 2 is also transmitted to the third controllable switch unit 6, and at this time, the third controllable switch unit 6 can normally receive the first voltage signal after being turned on, and then the third controllable switch unit 6 sends the first voltage signal 5 to the first controllable switch 4 and the third controllable switch unit 6 in the third transmission control unit 2, and so on, the subsequent operations are similar, and are not repeated here.

After the first controllable switch unit 4 and the third controllable switch unit 6 of the last transmission control unit receive the first voltage signal 5 from the third controllable switch unit 6 of the last transmission control unit, a second voltage signal is sent to the last slave device 3 connected with the first controllable switch unit, after the last slave device 3 acquires the assigned permission from the master device 1 and performs the charging or discharging operation, the third controllable switch unit 6 of the last transmission control unit 2 continues to send the first voltage signal backwards, but since the third controllable switch unit 6 of the last transmission control unit 2 is grounded, the first voltage signal is transmitted to the ground terminal, so as to ensure the stable operation of the whole circuit.

When the main device 1 controls the switch to be turned on, the voltage signal generated by the second power supply 11 sends a first signal to the first controllable switch unit 4 through the switch, so that the first controllable switch unit 4 is turned on.

Optionally, as shown in fig. 6, the third controllable switch unit 6 of the last transmission control unit 2 is also directly connected with the master device 1; the third resistor 9 is electrically connected between the connection point of the third controllable switch unit 6 and the main device 1 and the ground; when the master device 1 detects the voltage jump of the connection point, it is determined that the rights allocation of the plurality of slave devices 3 is completed.

When the main device 1 controls the control switch to be turned on, a 12V voltage signal (first signal) generated by the second power supply 11 passes through the switch to reach the K0 (1) end of the light emitting diode of the third opto-coupler switch, the voltage signal passes through the light emitting diode of the third opto-coupler switch and then reaches the connection point K0 (2) of the light emitting diode of the third opto-coupler switch, then passes through the connection point K1 (1) and reaches the base of the triode, 12V voltage is generated at the collector of the triode, the first power supply 10 generates 24V voltage signal, the 24V voltage signal generated by the first power supply 10 and the 12V voltage signal generated by the collector of the triode form a voltage difference, so that current is generated between the first power supply 10 and the triode, meanwhile, the triode is turned on, the 24V voltage signal (second signal) output by the first power supply 10 enables the light emitting diode of the first opto-coupler switch to start to emit light, the phototriode of the first opto-coupler switch is conducted and outputs a 24V voltage signal (third signal), the voltage signal is transmitted to the slave device 3 through the voltage division of the first resistor 7, after the slave device 3 receives the corresponding voltage signal, the assigned authority is obtained to carry out charging or discharging operation, then a certain value of voltage is output to the light emitting diode of the second opto-coupler switch through the second resistor 8, because the voltage of one end of the light emitting diode of the second opto-coupler switch, which is grounded, is 0V, the voltage of the certain value is output through the light emitting diode of the second opto-coupler switch and the voltage of the grounded end generate a pressure difference, the light emitting diode of the second opto-coupler switch emits light, so that the phototriode of the second opto-coupler switch is conducted, when the phototriode of the second opto-coupler switch is conducted, the voltage signal generated by the second power supply 11 passes through the phototriode of the second opto-coupler switch and passes through the connection point K1 (2), then the voltage signal is sent to the base electrode of the next triode through the connection point K2 (1), the follow-up process is similar to the previous process, and the follow-up process is not repeated here, when the voltage signal reaches the last transmission control unit module 2, after the phototriode of the second opto-coupler switch is conducted, the voltage signal generated by the second power supply passes through the connection point Kn (2) and then passes through the third resistor 9 to flow to the ground terminal.

When the 24V voltage signal passes through the connection point Kn (2) and then flows to the grounding end through the third resistor 9, the light emitting diode of the third optical coupler switch starts to emit light, and the phototriode of the third optical coupler switch is conducted, so that the master device 1 can determine that the authority allocation of the plurality of slave devices 3 is completed when detecting the 12V voltage signal.
