Equipment state management method

Abstract

The invention relates to an equipment state management method. The method comprises the steps as follows: when equipment starts operation, a manager builds a session, and uses a unique identifier of associated equipment as an ID for operating the session; each piece of equipment is corresponding to one session, and each session is corresponding to a plurality of states via a base class; the mangerreceives an external signal, the manager distributes the signal to the session of the corresponding equipment according to the session ID, and the session calls an entrance of the corresponding statefrom the base class according to the signal content, and performs corresponding state service processing. According to the method provided by the invention, the equipment is flexible in state management, good in function stability, and low in service processing logic coupling degree; each state does not need to concern what the previous state was, and does not need to concern which services needing to be processed by the other states, and only needs to concert what input signal is received by own state and process the corresponding service, or enter the next state.

Description

technical field [0001] The present invention relates to a device management method, in particular to a device state management method. Background technique [0002] In the prior art, there is generally a manager to manage the status of the equipment. There is an identifier used to represent the status in the manager, and the business corresponding to the status is processed according to the status identifier. Whenever the status of the equipment changes, the manager will The flag changes to the corresponding state. [0003] The existing equipment status management has the following shortcomings: 1. The code processing is not flexible enough. Before each business is processed, it is necessary to judge the current status through a conditional statement, and then decide what business to handle; 2. The business expansion is not flexible enough. If a new one is added state, you need to traverse all the business, and then add processing logic to the business that may need to be p...

[0003] The existing device status management has the following shortcomings: 1. The code processing is not flexible enough. Before processing each business, it is necessary to judge the current status through conditional statements, and then decide what business to process; 2. The business expansion is not flexible enough. If a new state, you need to traverse all the business, and then add processing logic to the business that may need to be processed, and the code changes are large, which may affect the original business logic, the risk is not easy to control, and the stability is poor

If a new device is added, the complexity of business processing will increase by far more than 1+1. High complexity will lead to poor management stability
