Further, the method according to the embodiment of the present invention is applied to different communication devices, and corresponding communication interfaces to be processed are also different, and in a specific embodiment of the present invention, the method is applied to an RRU device, and at this time, the communication interface may be, but is not limited to, an RS485 interface on the RRU device. That is to say, the RS485 interface is processed according to the method of the embodiment of the present invention, and the RS485 interface may be butted with the dry contact alarm device, so as to assist in implementing the dry contact function of the RRU device.
In one embodiment of the present invention, the communication interface is configured as an internal self loop by connecting a signal transmitting pin to a signal receiving pin within the communication interface. In this embodiment, in order to form two-way self-loop circuit, the communication interface should have a differential signal transmitting pin and a differential signal receiving pin.
When the communication interface has a differential signal transmitting pin and a differential signal receiving pin, the communication interface is configured as an internal self-loop, and specifically includes:
connecting the positive differential signal sending pin of the communication interface with the positive differential signal receiving pin of the communication interface;
and connecting the negative differential signal transmitting pin of the communication interface with the negative differential signal receiving pin of the communication interface.
In the embodiment of the invention, the connection between the pins can be carried out in the communication interface, and the connection between the pins can also be carried out outside the communication interface. In this embodiment, when the connection between the pins is performed outside the communication interface, the differential signal transmitting pin and the differential signal receiving pin are connected by an external cable. Specifically, the method comprises the following steps:
the positive differential signal transmitting pin and the positive differential signal receiving pin are connected through a first external cable;
the negative differential signal transmitting pin and the negative differential signal receiving pin are connected through a second external cable.
The external cable aims to realize connection between pins, so that the length of the external cable does not need to be too long, and only two pins need to be connected.
The following describes in detail how the RS485 interface is configured as a self-looping interface.
As shown in fig. 3, which is a schematic diagram of a four-wire RS485 interface, the RS485 interface includes a four-wire RS485 chip and an external socket connector (not shown in the figure), when the self-loop setting of the interface is performed, an external short cable is connected to the socket connector, and the RX + (i.e., the positive differential signal transmitting pin) and the TX + (i.e., the positive differential signal receiving pin) of the RS485 interface are reliably shorted, and the RX- (i.e., the negative differential signal transmitting pin) and the TX- (i.e., the negative differential signal receiving pin) of the RS485 interface are reliably shorted, and after the short-circuiting processing, the RS485 interface forms a self-loop, which is specifically shown in fig. 4.
Further, in an embodiment of the present invention, a manner of respectively setting access points on two self-loops includes: and setting access points on the first external cable and the second external cable respectively, wherein the set access points are suitable for being connected with the contact of the dry contact alarm device. As shown in fig. 5, a schematic diagram of two access points arranged on the external short-circuit cable of the self-loop of the RS485 interface is given.
In summary, the method of the embodiment of the invention is used for processing the existing communication interface, and the communication interface can be converted into the dry contact interface, so that the flexibility of the dry contact interface deployment is improved, and the deployment cost is reduced.
In a second embodiment of the present invention, a dry contact interface is provided, comprising: internally forming communication interfaces of two self-loop loops, wherein each self-loop is provided with an access point; wherein the access point is adapted to interface with a contact of a dry contact alarm device.
In the embodiment of the present invention, the communication interface is a communication interface capable of implementing a self-loop function, and may be, but is not limited to, an RS485 interface.
For a specific preparation method of the dry contact interface according to the embodiment of the present invention, reference may be made to the first embodiment, which is not described herein again.
The dry contact interface described in this embodiment is obtained by simply deforming a communication interface, and compared with a conventional dry contact interface, the dry contact interface has a small volume, low manufacturing cost, and is easy to implement.
In a third embodiment of the present invention, there is provided a communication apparatus, as shown in fig. 6, wherein: a communication interface 610 and means for implementing a dry contact alarm 620, wherein:
the communication interface 610 is processed to form two self-loop loops inside, and each self-loop is provided with an access point, and the access point is in butt joint with a contact of the dry contact alarm device;
the device 620 for realizing dry contact point alarm is used for sending a self-loop test signal to the communication interface 610, detecting whether the self-loop test signal sent back by the two self-loop circuits is received, and judging that the dry contact point alarm equipment gives an alarm when the self-loop test signal is not received.
The communication equipment of the embodiment of the invention can realize the butt joint with the dry contact point warning equipment by converting the communication interface into the dry contact point interface, and because the butt joint point with the dry contact point warning equipment is on the self-loop circuit, when the dry contact point is closed due to the alarm generated at the side of the dry contact point warning equipment, the self-loop circuit can not receive the self-loop test signal, and further, whether the dry contact point warning equipment generates the alarm can be monitored.
Further, in the embodiment of the present invention, the communication interface 610 interfaces with two contacts of the dry contact alarm device through a dry contact cable.
The selection of the dry contact cable is related to the alarm current of the dry contact alarm device, that is, the selected dry contact cable can bear the alarm current and is not fused. In one embodiment of the present invention, the dry contact cable is a category five network cable.
In an alternative embodiment of the present invention, as shown in fig. 7, the communication device further includes: a mode setting module 630 and a control module 640;
a mode setting module 630, configured to set an operating mode of the communication interface 610; the types of the working modes comprise: a dry contact alarm mode or a communication mode;
the communication interface 610 is processed to form two self-loop circuits inside in a dry contact point warning mode, and access points are respectively set on the two self-loop circuits, and the access points are in butt joint with contact points of dry contact point warning equipment;
and the control module 640 is configured to determine an operating mode of the communication interface 610, and turn on the apparatus 620 for implementing the dry contact alarm when the operating mode is the dry contact alarm mode.
That is to say, in this embodiment, the communication interface has two working modes, and when the communication interface is in the communication mode, the communication interface is used for communicating with other communication devices, that is, the communication interface functions normally; when the mode is the dry contact alarm mode, the communication interface is processed as a dry contact interface, and the detection of the dry contact alarm is realized. According to the embodiment, different mode settings are carried out on the communication interface, so that the use efficiency and the use flexibility of the communication interface are improved.
In a specific embodiment of the present invention, the communication device is a remote radio unit RRU, and at this time, the communication interface is a four-wire RS485 interface. In this embodiment, the external receptacle connector of the four-wire RS485 interface is connected to the external short cable, and the RS485 interface forms a self-loop. And an external dry contact cable with a proper length is connected with the dry contact alarm device after the external short cable is connected. When the alarm does not occur, the dry contact of the dry contact alarm equipment is disconnected, the self-loop test signal sent by the RS485 interface at the RX +/-interface can be correctly recovered at the TX +/-interface, when the alarm occurs, the dry contact of the dry contact alarm equipment is closed, the RX and TX interfaces of the RS485 interface are short-circuited, the self-loop test signal sent by the RX +/-interface cannot be correctly recovered at the TX +/-interface, and at the moment, the device test module for realizing the dry contact alarm can judge that the dry contact alarm exists.
Regarding the length of the external dry contact warning cable, as the RS485 communication length is generally limited to 120 meters, five types of network cables are adopted, the cable within 120 meters can be correctly warned after verification is carried out through experiments, and the warning can still be correctly realized after repeated experimental verification is carried out by increasing the length of the cable to 290 meters. It can be seen that the cable is only used for realizing short circuit of the RS485 communication transceiving port, and is not limited to the distance limit of 120 meters for RS485 communication.
In summary, the communication device provided in the embodiment of the present invention does not need to be specially equipped with a dry contact interface, and only needs to simply process the existing communication interface, so as to convert the communication interface into the dry contact interface, and when the dry contact interface is connected to the dry contact alarm device, the monitoring of the dry contact alarm can be implemented, thereby greatly improving the efficiency of the dry contact alarm monitoring.
In a fourth embodiment of the present invention, a method for implementing a dry contact alarm is provided, as shown in fig. 8, where the method includes:
step S801, sending a self-loop test signal to a communication interface; wherein the communication interface is a communication interface treated as a dry contact interface.
In this embodiment, the manner in which the communication interface is processed as the dry contact interface may refer to the first embodiment, and this embodiment is not described herein again. The communication interface processed by the method described in the first embodiment is a communication interface in which two self-loop circuits are formed inside the communication interface, and each self-loop circuit is provided with an access point which is in butt joint with a contact of the dry contact alarm device.
Step S802, detecting whether the self-loop test signals returned by the two self-loop circuits are received;
step S803, when it is detected that the data is not received, it is determined that the dry contact point alarm device connected with the communication interface gives an alarm.
Because the communication interface is processed as the dry contact interface, the butt joint with the dry contact alarm device can be realized, and the butt joint of the communication interface and the dry contact alarm device is considered to be on the self-loop circuit, when the dry contact is closed due to the alarm generated at the side of the dry contact alarm device, the self-loop circuit cannot receive the self-loop test signal.
In a fifth embodiment of the present invention, there is provided an apparatus for implementing a dry contact alarm, as shown in fig. 9, the apparatus comprising:
a signal sending module 910, configured to send a self-loop test signal to the communication interface; the communication interface is a communication interface internally forming two self-loop loops, and each self-loop is provided with an access point which is in butt joint with a contact of a dry contact alarm device;
and the alarm detection module 920 is configured to detect whether the self-loop test signal returned by the two self-loop circuits is received, and determine that the dry contact alarm device connected to the communication interface alarms when the self-loop test signal is not received.
In the embodiment of the present invention, the communication interface is a communication interface processed as a dry contact interface.
In this embodiment, the manner in which the communication interface is processed as the dry contact interface may refer to the first embodiment, and this embodiment is not described herein again. The communication interface processed by the method described in the first embodiment is a communication interface in which two self-loop circuits are formed inside the communication interface, and each self-loop circuit is provided with an access point which is in butt joint with a contact of the dry contact alarm device.
Because the communication interface is processed as the dry contact interface, the butt joint with the dry contact warning device can be realized, and the butt joint of the communication interface and the dry contact warning device is considered to be on the self-loop circuit, when the dry contact is closed due to the alarm generated on the side of the dry contact warning device, the self-loop circuit cannot receive the self-loop test signal, and then the device can carry out alarm monitoring on the dry contact warning device by sending the self-loop test signal to the communication interface.
In a sixth embodiment of the present invention, there is provided a communication apparatus, as shown in fig. 10, including: a communication interface 1010, a memory 1020, and a processor 1030;
the communication interface 1010 is processed to form two self-loop loops inside, each self-loop is provided with an access point, and the access points are in butt joint with the contact points of the dry contact point alarm device; that is, the communication interface 1010 may be treated as a dry contact interface and interface with two contacts of a dry contact. For a processing manner of the dry contact interface, reference may be made to the first embodiment, which is not described in detail in this embodiment.
The memory 1020 stores computer instructions that are executed by the processor 1030 to implement the method of:
sending a self-loop test signal to the communication interface;
detecting whether the self-loop test signals returned by the two self-loop circuits are received or not;
when the non-reception is detected, the dry contact point alarming equipment connected with the communication interface is judged to alarm.
The communication equipment of the embodiment of the invention can realize the butt joint with the dry contact of the alarm equipment by converting the communication interface into the dry contact interface, and because the butt joint with the dry contact is on the self-loop circuit, when the dry contact is closed due to the alarm of the alarm equipment side, the self-loop circuit can not receive the self-loop test signal, thereby monitoring the dry contact alarm.
In an optional embodiment of the invention, processor 1030 sets the operating mode of communication interface 1010 as needed; the working modes comprise: a dry contact alarm mode or a normal operating mode. And the processor 1030 performs sending of the self-loop test signal and detection of the dry contact alarm only when the working mode of the communication interface is set to be the dry contact alarm mode. The communication interface 1010 is also configured to be handled as a dry contact interface and interface with two contacts of a dry contact only if it is set to a dry contact alert mode.
That is to say, in this embodiment, the communication interface has two operation modes, when the operation mode is the normal operation mode, the communication interface is used for communicating with other communication devices, and when the operation mode is the dry contact alarm mode, the communication interface is processed as the dry contact interface, so as to implement the detection of the dry contact alarm. According to the embodiment, different mode settings are carried out on the communication interface, so that the use efficiency and the use flexibility of the communication interface are improved.
In a specific embodiment of the present invention, the communication device is a remote radio unit RRU, and at this time, the communication interface is a four-wire RS485 interface.
In summary, the communication device provided in the embodiment of the present invention does not need to be specially equipped with a dry contact interface, and only needs to simply process the existing communication interface, so as to convert the communication interface into the dry contact interface, and when the dry contact interface is connected to the dry contact alarm device, the monitoring of the dry contact alarm can be implemented, thereby greatly improving the efficiency of the dry contact alarm monitoring.
In a seventh embodiment of the present invention, a system for implementing a dry contact alarm is provided, as shown in fig. 11, including: the communication device 1110 and the dry contact alarm device 1120 according to the third or sixth embodiment, wherein:
the structure and function of the communication device 1110 are described in detail in the third or sixth embodiment, and are not described in detail here.
And a dry contact alarm device 1120, connected to the communication interface of the communication device 1110, for closing a dry contact in the device to trigger a dry contact alarm when an alarm is present.
That is, when the external dry contact alarm device 1120 alarms, the dry contact is closed, and the communication device 1110 may perform dry contact alarm detection by whether or not it receives the self-loop test signal.
The following describes the implementation process of the system according to this embodiment in more detail with reference to a specific application scenario.
The present embodiment provides a system for implementing a dry contact alarm, which is applied to an external site of a base station in a wireless communication system. The external site usually has a plurality of RRU devices, and each RRU device usually reserves an RS485 interface for external connection of devices such as a GPRS module.
When the RGPS function is required, one RRU device is usually selected from multiple RRU devices in one site and externally connected to an RGPS module. At the moment, if the station is required to be externally connected with dry contact point alarm equipment such as a lightning protection box and the like, the RRU equipment with an idle RS485 interface can be selected, the RS485 interface of the RRU equipment is processed and converted into a dry contact point interface, the dry contact point interface is in butt joint with a dry contact point of the lightning protection box, and the dry contact point alarm function is realized through a test module in the RRU equipment.
In the system of the embodiment, the RS485 interface is multiplexed into the dry contact interface, so that the dry contact alarm function is realized on the RRU under the condition of no need of hardware reprinting, the convenience of realizing the alarm function is improved, and the realization cost is reduced.
