Embodiment Construction
[0021] Multiple intranets of the cable TV signal monitoring network system are connected through routers and firewalls, such as figure 1 , one of the intranets is connected with a network management server and three monitors, the network management server is equipped with a registration server and a monitoring server, and the intranet is connected to the monitors in another intranet through a firewall and a router. If the monitor also has the function of controlling the monitoring point, it can also be called a monitor.
[0022] The network operates as figure 2 , detailed below.
[0023] When the monitor monitors the cable TV signal, it sends out the registration information continuously, and the interval between sending out the registration information twice is shorter than a set time length. The registration server receives the registration information sent by the monitor, and then records the working status of the monitor as online; if it does not receive the registratio...

The invention relates to an operation method of a CATV signal monitoring network and a CATV signal monitoring network system. The invention aims at solving the problem that the complex operation of procedure validation before transmitting information between two equipments in the CATV signal monitoring network causes low transmission efficiency. The invention provides the operation method of the CATV signal monitoring network, which is characterized in that a monitor uninterruptedly sends out registration information and the interval between twice sending of the registration information is shorter than a set duration; the registration information sent out by the monitor is received and the operating mode of the monitor is recorded as on-line; if the registration information of the monitor is not received in the set duration, the operating mode of the monitor is recorded as off-line; when the transmitting equipment requests to transmit information to one monitor, the operating mode of the monitor is inquired; if the operating mode is inquired to be off-line, the transmission is not conducted; if the operating mode is inquired to be on-line, the transmission is conducted. The invention also provides the CATV signal monitoring network system.
Description
technical field [0001] The invention relates to an operation method of a cable television signal monitoring network and a cable television signal monitoring network system. Background technique [0002] Patent document CN101365145 records a cable TV signal monitoring system, which includes monitors and system management equipment, used to monitor various signals in the cable TV network, the main function is to quickly determine the fault point and fault type in the cable TV network— - In this document, the monitor also has the function of controlling the monitoring point (such as cutting off or opening the monitored line or node), so the document is called a monitoring device. In practical applications, in order to facilitate data transmission, multiple monitors in the system need to be connected to the network. This network is called the cable TV signal monitoring network in this paper. The network can be constructed separately, or it can share the same transmission networ...
