Embodiment 1
[0030] figure 1 It is a flow chart of the data access method of the comprehensive collection and control system provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation that data access in the comprehensive collection and control system needs to deal with the congestion situation, and the method can be implemented by the comprehensive collection and control system. Execute by the central host in the system, specifically including steps 110 to 150 as follows:
[0031] Step 110, receiving a data access request;
[0032] Wherein, the request for data access includes the identification of the target fully mechanized mining equipment and the type of access data packet, and the type of the access data packet includes an operation control data packet or a working status monitoring data packet; the operation control data packet is used to read the device The current operating conditions (such as the current position of the equipment, the heigh...
