Detailed Description
The invention is described in further detail below with reference to the figures and specific examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1 to 5, the control communication method of the financial self-service device of the invention comprises the following steps,
1) establishing connection: the control side sends a handshake request packet to the financial self-service equipment, the financial self-service equipment replies a handshake response packet to the control side after receiving the handshake request packet, the communication connection between the control side and the financial self-service equipment is successfully established after the process is carried out twice, and the next handshake has the function of confirming the successful reception of the 'reply handshake response packet' sent in the front, so that the normal and smooth establishment of the connection is ensured; the communication medium for the communication between the control party and the financial self-service equipment can be in any form of RS-232 or USB and the like;
2) and idle time communication step: the control party sends a handshake request packet to the financial self-service equipment periodically, for example, every 150-250ms, and the equipment replies a handshake response packet to the control party after receiving the handshake request packet; the intermittent communication during idle can ensure that the controller can know the running state of the financial self-service equipment in real time,
3) a control command sending step, in which a control party sends a control command to the financial self-service equipment, the financial self-service equipment replies a confirmation packet to the financial self-service equipment after receiving the control command, the control party sends a handshake request packet to the financial self-service equipment, the financial self-service equipment replies a handshake response packet to the financial self-service equipment, and then the financial self-service equipment starts to execute the command; the purpose of multiple handshaking before the transmission of the control command is to ensure the success of communication certainty, prevent misoperation, command missending and the like; meanwhile, multiple handshakes require that communication contents are completely correct, so that actions such as wrong information or malicious attacks can be effectively avoided.
4) A step of obtaining the working state, during the execution of the control command by the financial self-service device, the control party periodically sends a handshake request packet to the financial self-service device, for example, every 150 plus 250ms, when:
(1) when the financial self-service equipment works normally, the financial self-service equipment returns a handshake response packet to the financial self-service equipment;
(2) when the financial self-service equipment is abnormal, the financial self-service equipment returns an equipment abnormal packet to the financial self-service equipment; the equipment exception packet comprises an exception error code, and a controller can respectively process the exception packet according to error information;
(3) when the financial self-service equipment finishes executing the command, the financial self-service equipment returns a command response packet to the financial self-service equipment;
after receiving the equipment exception packet or the command response packet sent by the financial self-service equipment, the control party sends a confirmation packet to the financial self-service equipment to indicate that the equipment exception packet or the command response packet is received, and the financial self-service equipment sends a handshake response packet to the control party after receiving the confirmation packet; meanwhile, the control party performs corresponding processing according to the error or abnormal information, such as information reporting, link disconnection, or operation of restarting the financial self-service equipment, and the like, wherein each packet has a fixed data format, so that personnel can be prevented from simulating communication according to the data format, and the circulating machine core is directly controlled;
5) and a disconnection step, namely when the financial self-service equipment is powered off or crashes, the control party does not receive a response after sending any message packet, and at the moment, the control party retransmits the message packet for multiple times at intervals, such as three times, four times or five times at intervals of 250ms, and if no response is received, the equipment is considered to be in failure, and the connection is disconnected.
The beneficial effects are that: under the communication method, the control party and the financial self-service equipment keep real-time communication, the control party can know the current state of the financial self-service equipment in real time, and the control party can know fault information at most 1 second after the equipment breaks down, so that clients and workers can be informed in time, and the waiting time of the users is reduced.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
