The protocol can standardize communication among various devices of different manufacturers in the bank safety door system, and technical parameter requirements of each communication way to facilitate efficient communication among various systems in a bank, avoid repeated installation and unnecessary waste of devices, reduce bank cost and increase working and management efficiency.
Description
Technical field
The present invention relates to a kind of communication protocol implementation method, a kind of implementation method of bank safety door system communication protocol particularly is mainly used in the implementation method of the communication between each equipment of bank safety door system.
Background technology
The safety door system that present most of bank adopts is the autonomous control system of non-networking, can only carry out execute-in-place in this site, and without any operation note, management to the related personnel can't be supervised, do not have record afterwards, can not carry out relevant inquiring, do not have real-time status to detect, for administrative staff, must be in the action and just can see state.
Some emergency exit equipment is with the local record hold function, can be afterwards at the local search record, and need to connect at the scene computer and read record and inquire about, operate more loaded down with trivial details.
The emergency exit product of some networking can carry out various operations in the administrative center of banking system in addition, is worthy to be popularized, but because the product of each producer does not have industry standard, from ordering, Comparison of Management is mixed and disorderly by producer for the communication protocol of each safety door system, is unfavorable for promoting.Under this situation, be badly in need of a kind of general bank safety door system communication protocol, the emergency exit communication system is carried out standard, make it easy to inquire about and various operation at host computer, improve fail safe, ease for operation and the versatility of bank safety door system.
Summary of the invention
In order to overcome the problem of above-mentioned prior art, the invention provides a kind of implementation method of bank safety door system communication protocol, but the communication in the standard bank safety door system between the various device of different manufacturers, and the technical parameter requirement of various communication modes, make that various systems can effectively communicate by letter, link up in the bank, avoid equipment repeat reduction bank cost, raising work and the efficiency of management are installed and unnecessary waste.
The present invention overcomes the above problems the technical scheme that adopts:
The implementation method of bank safety door system communication protocol, comprise general purpose controller, host computer, emergency exit equipment and bus network, described bus network comprises serial communication interface, router and network connection, described general purpose controller is connected with host computer by bus network, host computer can connect some controllers simultaneously, each controller is by emergency exit interface and emergency exit equipment connection, described general purpose controller is namely to establish communication protocol, order according to host computer, the state of emergency exit equipment is conducted interviews and controls, and the state information of emergency exit equipment transferred to host computer by bus network, the step of communication protocol implementation method is:
1) host computer sends query statement, the response format of corresponding controllers to the controller of certain address coding;
2) host computer sends the controller of certain address coding and instruction is set, the response format of corresponding controllers;
3) host computer sends control command, the response format of corresponding controllers to the controller of certain address coding.
Wherein, query statement is used for the various states of inquiry corresponding controllers, such as information such as time, temperature, alarm condition, voltages; The authority of opening the door, time and various parameter that instruction is used for arranging corresponding controllers are set; Control command is used for the control corresponding controllers and uploads various information, as open the door, warning etc., and the various operational orders that send of host computer.Host computer can connect the controller of a plurality of different geocodings, by each controller of various instruction access, shows and store the state of each controller.
16 system packet structures are all adopted in the various instructions that host computer sends, and the response format of controller response host computer instruction, and its content comprises initial symbol, length symbol, command characteristics code, numeric data code, check character and end mark, and is as shown in table 1:
Table 1
| Initial symbol | The length symbol | The command characteristics code | Numeric data code | Check character | End mark |
| 1 byte | 1 byte | 2 bytes | Variable-length | 1 byte | 1 byte |
Wherein, initial symbol is made of 1 byte, can be according to the device type adjustment that adds up, as shown in table 2:
Table 2
| Numerical value | The emergency exit type |
| 0x53 | Anti-prizing safety door |
| 0x54 | Anti-following linkage interlocking safety door |
But this theme is not limited to numerical value and the emergency exit type that illustrates.
The length symbol is the length sum of command characteristics code and numeric data code.
The command characteristics code is made of 2 bytes, represents concrete Content of Communication.
The numeric data code variable-length, the data message that expression is additional is such as card number, time, state etc., if no data content is then filled with four 0x00.
Check character is made of 1 byte, and expression is by length symbol, command characteristics code and each byte XOR income value of numeric data code.
End mark is made of 1 byte, and the end of presentation directives is fixed value 0x43.
This agreement can be carried out standard to common several communication modes, and the connection request between the distinct device is avoided communication failure.
As adopt the RS232 communication mode, and then requiring baud rate is 9600, the no parity check position, and numeric data code is 8, communication distance is not more than 15 meters;
As adopt the RS485 communication mode, and then requiring baud rate is 9600, the no parity check position, and numeric data code is 8, communication distance is not more than 1000 meters;
As adopt the tcp/ip communication mode, and then requiring to adopt UDP communication, communication port is defaulted as 50000, and it is 38183 that system arranges port.If need the across a network bridging router, then should set in advance, guarantee that communication is normal.
In addition, require between two communication datas at least interval 50ms, receive in time return information of data, so that the other side judges and processes.
The invention has the beneficial effects as follows, but the communication in this agreement standard bank safety door system between the various device of different manufacturers, and the technical parameter requirement of various communication modes, make that various systems can effectively communicate by letter, link up in the bank, avoid equipment repeat install and unnecessary waste, reduce bank's cost, raising work and the efficiency of management.
