Embodiment Construction

[0051] Fig. 1 is the flowchart of the first embodiment of the method for processing slave parameters in the distributed master-slave communication of the present invention. It is carried out when the system is working or when the system is reset. When the system is working normally, since the above S11-S12 settings have been completed, it only needs to be processed in step S13 according to the received command. The detailed description of the above steps is as follows:

[0052] S11 sets the start address, length and content of the slave device number table: set the start address and length of the slave device number table corresponding to the slave number on the host storage device, and set the slave device number Table; the slave device number table establishes the connection between the slave number and the slave address, so that the address of the slave can be obtained from the slave number or the number of the slave can be obtained from the address of the slave, see Figure...

Abstract

The invention relates to a processing method for parameters of a slave in a distributed master-slave communication, including the following steps: an initial address and length of the initial address of a slave device number table corresponding to a slave number are set, and the slave device number table is set; slave parameter types are set, the slave parameter length and the initial address of each type are set according to the slave device number table and the slave parameter types; an address of a parameter which is about to be operated is received according to a slave address, the parameter type and an operation type in a command or a request currently received by a master, thereby obtaining or updating the value of the parameter, the value of the parameter is transmitted or operated immediately or after traversing the slave according to the command or the request. The invention also relates to a device for achieving the method. The processing method and the device for parameters of the slave in the distributed master-slave communication for implementing the invention have the advantages of short processing period and high system efficiency.

Description

technical field [0001] The invention relates to the monitoring field in a network coverage system, and more specifically relates to a method and device for processing slave machine parameters in distributed master-slave machine communication. Background technique [0002] In the field of monitoring in the existing network coverage system, in order to realize the centralized management of related sites, low-cost operation of distributed monitoring applications has become quite common. The master and slave machines are scattered on the parallel network formed by the bus, and the master communicates with the slave machines through the parallel network formed by the bus; the master is usually connected to the upper-level management device or runs management software on the host. Usually, when receiving an order from the upper-level management device or management software, the master uses the broadcast communication method to be responsible for sending the query information of t...
