Detailed Description
In one embodiment, a device address configuration system in a communication system is provided, as shown in fig. 1, including a monitoring master device 102, a slave device 104, and a bridge cable, where the monitoring master device and each level of slave devices are connected by the bridge cable in a star or daisy chain manner. The data bus in one embodiment may be an RS485 bus.
The monitoring master device 102 is configured to, when it is detected that a slave device accesses, assign an address to the accessed slave device, and send address information assigned to the accessed slave device.
The slave device 104 is configured to, when detecting that a next-stage slave device is accessed, allocate an address to the next-stage slave device according to the address of the slave device, send the allocated address information to the next-stage slave device, and report an access state and address information of the next-stage slave device to the monitoring master device 102.
As shown in fig. 1, the monitoring master has a cascade interface (Next), and the slave has a cascade interface (Next) and a resource interface (Source). The cascade interface of the monitoring master device is connected with the resource interface of the first-level slave device through a bus, and the cascade interface of the Nth-level slave device is connected with the resource interface of the (N + 1) th-level slave device through the bus. It should be understood that, in a communication system, the cascade interfaces and the resource interfaces of the monitoring master device and the slave devices at different levels are the same, that is, the interfaces of the monitoring master device and the slave devices in the communication system are uniform, and the slave devices can be alternatively used, thereby facilitating the device development and engineering maintenance.
Meanwhile, in view of the requirement of cable universality, in a specific implementation mode, a data bus can be realized by selecting the most common direct connection network cable, the engineering practicability is strong, and Ethernet interfaces are correspondingly selected as communication interfaces for all levels of connection interfaces and resource interfaces, so that the Ethernet interface without an isolation transformer is recommended to be selected because the communication speed of the monitoring bus is low and the communication distance between systems is not too far. The access mode of the monitoring master device and the monitoring slave device can be star-shaped or daisy-chained.
In one embodiment, the interfaces of the monitoring master and slave are unified, including address line pins ADDR1 and ADDR2, and bit detect pin DI. In a specific embodiment, the definition of the sequence of the buses for connecting the interfaces is shown in table 1.
TABLE 1 line order definition of the bus
| Line sequence | Definition of | Description of the |

| 8 | SLAVE_ADDR1 | |
The lines with the serial numbers of the bus correspond to the pins of the interface, and the line 1 and the line 2 can form a double-stranded wire to be used as an independent RS485 bus and be used as a master-slave device communication bus. Lines 3 and 6 are used as reservations, may be used for device telecommunication buses, or to extend slave address bits, etc. The connectors of the bridge cables corresponding to the bus line sequence are also required to be uniform. In one particular embodiment, the cable connector is an RJ-45 connector, i.e., a "crystal head". The cable can carry out length adjustment according to the actual engineering application of equipment, and engineering application convenient and fast, stability are high.
In one embodiment, a schematic structural diagram of a cascade interface of a monitoring master device is shown in fig. 2. And an address line pin of the cascade interface of the monitoring master device is connected with a pull-down resistor, and the default level is a low level. Specifically, this is achieved by a strong pull-down of the 56 ohm resistor. The on-line detection pin is defaulted to a high level through a pull-up resistor, and specifically is realized through weak pull-up of a 10K ohm resistor.
In one embodiment, a schematic structural diagram of a cascade interface of a slave device is shown in fig. 3. And an address line pin and an on-position detection pin of the cascade interface of the slave device are pulled up through resistors, and the default level is high level. In particular, the pull-up is realized by a weak pull-up of 10K ohm resistance.
In one embodiment, a schematic structural diagram of the resource interface of the slave device is shown in fig. 4, an address line pin and a bit detection pin of the resource interface of the slave device are pulled down through a resistor, and a default level is a low level. The address line pin is realized by weak pull-down of 10K ohm resistance, and the on-site detection pin is realized by strong pull-down of 56 ohm resistance.
When the slave device is connected to the monitoring master device, the low level 0 is given through the on-position detection pin of the resource interface, the level signal of the on-position detection pin of the cascade interface of the monitoring master device is converted from the default high level to the low level, and the monitoring master device judges whether the slave device is connected according to the change of the level signal of the on-position detection pin of the cascade interface of the monitoring master device. When the next-stage slave device is connected to the previous-stage slave device, the low level is given out through the on-position detection pin of the resource interface, the level signal of the on-position detection pin of the cascade interface of the previous-stage slave device is converted from the default high level to the low level, and the previous-stage slave device judges whether the slave device is connected according to the change of the level signal of the on-position detection pin of the cascade interface.
When the monitoring master detects that a slave device is accessed, the address assigned to the accessed slave device through the address line pin of the cascade interface is all zero, for example, the monitoring master directly controls the address line pins ADDR1 and ADDR2 of the cascade interface to be low level through a hardware circuit. And the slave equipment receives the corresponding level signal through the address line of the resource interface of the slave equipment and acquires the allocated address information.
It should be understood that when a slave device detects that the bit detection pin of its cascade interface is high, it is said to be the last stage of the link, and no next-stage slave device is connected behind it. When the slave device detects that the in-place detection pin of the cascade interface of the slave device is changed from low level to high level, the next-stage slave device is removed, the removal information is reported to the monitoring master device, the removal information comprises address information of the next-stage slave device, and the monitoring master device removes control over the slave device, so that the integrity of the system is guaranteed.
When the slave device detects that the next-stage slave device is accessed, the address allocated to the accessed next-stage slave device through the address line pin of the cascade interface is the self address + 1. For example, when the first-level slave device detects that the next-level slave device is accessed, the two address line pins ADDR1 and ADDR2 of the cascade interface are set to 0 and 1, respectively. When the second-level slave device detects that the next-level slave device is accessed, the two address line pins ADDR1 and ADDR2 of the cascade interface are respectively set to 1 and 0. And so on for the address line pins of the other interfaces.
In the device address configuration system in the communication system, since the address of the slave device is allocated by the monitoring master device after being accessed to the monitoring master device or the upper-level slave device, or is allocated according to the address of the upper-level slave device, the address can be automatically allocated to the slave device in the communication system without manual pre-configuration, and the efficiency is high. Meanwhile, the communication mode between the monitoring master device and the slave device and between the slave device and the next-level slave device is simple, the monitoring master device is only responsible for detecting the configuration condition of the first-level slave device, each level of slave device is also only responsible for detecting the configuration condition of the next-level slave device, the detection result is interacted with the monitoring master device through the communication of the master device and the slave device, the influence of environmental factors in the networking configuration process is small, and the stability is high.
In one embodiment, a device address configuration method in a communication system is provided, which is applied to the monitoring master device 102 or the slave device in fig. 5. As shown in fig. 6, the method comprises the steps of:
s502: and the current equipment detects whether equipment is accessed according to the on-site signal.
Specifically, the monitoring master device or the slave device judges whether a device is accessed according to a level signal of an in-place detection pin of the cascade interface. When the slave device is connected to the upper-level device, the low-level signal is sent to the on-position detection pin of the cascade interface of the monitoring main device through the on-position detection pin of the resource interface of the slave device, and the on-position detection pin of the upper-level device is converted from high level to low level. The upper level device may be a monitoring master device or a slave device.
S504: when the device is detected to be accessed, an address is allocated to the accessed device.
If the current device is the monitoring master device, when detecting that the device is accessed, the address allocated to the accessed device is all zero. Specifically, when a device access is detected, the address line pins ADDR1 and ADDR2 of the cascade interface are set to the initial level 0, 0, and the level signal is sent to the address line pin of the resource interface of the slave device 1 through the data bus. The specific address is associated with an address line pin of the interface. For example, when two address line pins are used, the address of the first-stage slave device is 0.0, and when four address line pins are used, the address of the first-stage slave device is 0.0.0.0.
If the current device is a slave device, when the access of the device is detected, an address is allocated to the accessed device according to the address of the current device, and specifically, when the access of the device is detected, an address line pin of the cascade interface is set to a corresponding level to allocate an address to the accessed slave device. Specifically, the address allocated to the accessed device is the address +1 of the current device. For example, if the address of the first level slave device is 0.0, the address allocated to the second level slave device is 0.1. For another example, if the address of the first level slave device is 0.0.0.0, then the address assigned to the second level slave device is 0.0.0.1, and so on for the other levels of slave devices.
S506: and sending the allocated address information to the accessed equipment, and reporting the access state and the address information of the accessed equipment to the monitoring main equipment. In this embodiment, when the slave device detects that the accessed next-stage slave device is removed, the removal information is reported to the monitoring master device, and the monitoring master device removes the control on the removed slave device, thereby ensuring the integrity of the system.
According to the device address configuration method in the communication system, the address of the slave device is allocated to the accessed device by the current device after the current device is accessed, so that the address can be automatically allocated to the slave device in the communication system without manual pre-configuration, and the efficiency is high. Meanwhile, the communication mode of the monitoring master device and the monitoring slave device is simple, the monitoring master device is only responsible for detecting the configuration condition of the first-stage slave device, each stage of slave device is also only responsible for detecting the configuration condition of the next-stage slave device, the detection result is interacted with the monitoring master device through the communication of the master device and the slave device, the influence of environmental factors on the networking configuration process is small, and the stability is high.

According to the device address configuration device in the communication system, the address of the slave device is allocated to the accessed device by the current device after the current device is accessed, so that the address can be automatically allocated to the slave device in the communication system without manual pre-configuration, and the efficiency is high. Meanwhile, the communication mode of the monitoring master device and the monitoring slave device is simple, the monitoring master device is only responsible for detecting the configuration condition of the first-stage slave device, each stage of slave device is also only responsible for detecting the configuration condition of the next-stage slave device, the detection result is interacted with the monitoring master device through the communication of the master device and the slave device, the influence of environmental factors on the networking configuration process is small, and the stability is high.

step 1: and the high level of an in-place detection pin of the cascade interface of the monitoring master device is converted into the low level, the address line pins ADDR1 and ADDR2 of the cascade interface are set to initial levels 0 and 0 when the access of the slave device 1 is detected.
Specifically, when the slave device 1 accesses the monitoring master device, the in-place detection pin of the resource interface thereof sends a low level signal to the in-place detection pin of the cascade interface of the monitoring master device, and the in-place detection pin of the monitoring master device is changed from a high level to a low level. At the same time, the monitoring master device sets the address line pins ADDR1 and ADDR2 of its cascade interface to initial level 0, 0, and sends the level signal to the address line pin of the resource interface of the slave device 1 through the bridge cable.
Step 2: the slave device 1 receives the assigned address information via the address line pins of its resource interface. The on-bit detection pin of the cascade interface of the slave 1 switches from high level to low level, detects that the slave 2 is accessed, and sets the address line pins ADDR1 and ADDR2 of the cascade interface to 0, 1.
And step 3: the slave device 2 receives the assigned address information via the address line pins of its resource interface.
