Problems solved by technology
[0003] 1. If the first storage unit is damaged or fails, although the data in the second storage unit is not damaged, the user will be unable to start the system due to the failure or damage of the first storage unit, resulting in multi-day downtime losses
[0004] 2. If the second storage unit fails or is damaged, although the first storage unit can be used for normal startup, the system still cannot work normally because the second storage unit has been damaged; and it is very difficult to rebuild after data loss
[0005] This shows that above-mentioned existing mode still has many defects, is not a good design, and urgently needs to be improved

Embodiment Construction
[0012] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.
[0013] see figure 1 As shown, it is a flow chart of the startup method applied in the controller provided by the present invention, and its step flow is:
[0014] Step 1: Set at least two startup units in the controller first, and store the system program and data in at least two startup units in advance or at the same time, and set one of the startup units as the main startup unit, and the other startup units are all It is a backup starting unit; in addition, the described starting unit is preferably two;
[0015] Step 2: During the startup process of the controller, the system program will first check whether the main startup unit exists (101), if not, it will automatically drive the backup startup unit to start the controller (102);
[0016] Step 3: If the system program detects that the main boot uni...

The invention relates to a starting method and system applied to a controller. At least two starting units are arranged in the controller, one of the starting units is set as a main starting unit, other starting units are set as back-up starting units, and a system program and data are stored in the main starting unit and the back-up starting units in advance or simultaneously; when the main starting unit generates damage or failure, the work and a task of the main starting unit are continued by the back-up starting units so as to enable the controller to be capable of continuously maintaining normal operation, therefore, the invention can ensure that a user or a manufacturer does not cause shutdown loss due to the failure or the damage generated in the main starting unit of the production machinery equipment. When the main starting unit is repaired, the back-up starting units can automatically backup the system program and the data to the main starting unit again and automatically replies that the main starting unit is in charge of the starting of the system program and the storage of the data of the controller again.
Description
technical field [0001] The present invention relates to a method and system for starting a device, in particular to a system program that can solve the problem that the controller cannot be started due to failure or damage of the starting unit, resulting in downtime losses, and can solve the problem of the system program when the starting unit is repaired. Application of the data reconstruction problem in a controller startup method and system. Background technique [0002] Existing controllers usually use two storage units, the first storage unit is used for system program startup, and the second startup unit is used for system program data storage. However, although the existing controller can perform normal startup and data storage through the application of two storage units, it still has the following defects in its composition: [0003] 1. If the first storage unit is damaged or malfunctioned, although the data in the second storage unit is not damaged, the user may n...
