Under the condition that system modules are limited or some modules are not required to be used by an owner, how to realize the control of the existing equipment by adopting other modules is a problem which needs to be solved urgently.
The control system and method are exemplified by the STC system, but the control method and system are not limited to be used in the STC system.
The invention provides a method for controlling turnout equipment and scattered equipment by adopting a general input/output module, which is characterized by limiting the use of turnout modules in an STC system, realizing the interface design between target controller logic and interlocking logic part by adopting a full electronic mode under the condition of not adopting the turnout modules, and concretely comprising the following two steps:

The second step: through adopting general input/output module, be connected communication with switch relay and scattered equipment relay, control and gather the state of relay, when realizing switch and scattered equipment control, can guarantee that the relay control logic of switch and scattered equipment is not modified.
The communication among the full electronic general module, the turnout module and the scattered equipment comprises the following steps: communication between the full electronic general output module and the full electronic general input module; the system comprises a full-electronic general input module, a turnout acquisition relay and a scattered equipment acquisition relay, wherein the full-electronic general input module is used for acquiring communication among the turnout acquisition relay and the scattered equipment acquisition relay; and the full-electronic general output module, the turnout driving relay and the scattered equipment driving relay are communicated with each other.
Aiming at the defects of the control mode of signal equipment in the traditional interlocking system, the invention provides a control method combining the advantages of relay control and full electronic module control, and different control modes are adopted according to different signal equipment and the type and the scale of a station.
The control system provided by the invention comprises a full electronic general module, a turnout module and scattered equipment, wherein the system adopts the full electronic general module to control the turnout module and the scattered equipment;
the full-electronic general input module acquires states of a turnout relay and a scattered equipment relay;
combining corresponding turnout position information according to the states of the turnout relays and combining corresponding scattered equipment state information according to the states of the scattered equipment relays;
and the full-electronic general output module outputs control information according to the turnout position information and the scattered state position information.
As shown in fig. 3, the STC system adopts a redundant communication network, and the human-computer operation display unit, the host, the full electronic signal module, the full electronic general input module, and the full electronic general output module are connected to the redundant communication network; wherein, the host computer adopts a two-by-two or two-by-two mode. The full electronic signal module, the full electronic general input module and the full electronic general output module jointly form a full electronic module. The full electronic signal module controls the annunciator, the full electronic general input module acquires states of the turnout acquisition relay and the scattered equipment acquisition relay, and the full electronic general output module outputs states of the turnout driving relay and the scattered equipment driving relay. Scattered equipment acquisition relay and scattered equipment drive relay are controlled by scattered equipment control system, switch acquisition relay and switch drive relay are controlled by switch control system, and scattered equipment control system and switch control system pass through outdoor relay circuit according to the state of gathering relay and drive relay promptly and act outdoor switch or scattered equipment, and the relay circuit this moment can adopt existing relay control logic.
When the STC logic part carries out calculation design, the lighting state of the annunciator is obtained from the annunciator module, and the states of the turnout acquisition relay and the scattered equipment relay are obtained from the all-electronic general input module. For single-opening switches, double-opening switches and related scattered equipment, the states of the switches generally exist in two types, for example, the switch states are set to be a positioning state and a reverse bit state, and in code logic operation, binary logic corresponding to 0 and 1 is adopted, 0 is positioning, and 1 is reverse bit.
The full-electronic general output module realizes the direct control of the turnout driving relay and the scattered equipment driving relay, and the driving voltage is adjustable. During design, judging the state or the driving command of the relay according to a data acquisition table of the relay, wherein the data acquisition table comprises a driving acquisition table and a state acquisition table; the driving acquisition table is provided with a driving data area and a driving relay number area, and each driving relay number corresponds to a unique bit of a unique byte of the driving data area; the state acquisition table is provided with an acquisition data area and an acquisition relay number area, and each acquisition relay number corresponds to a unique bit of a unique byte of the acquisition data area. In the logic design, a certain bit of a certain byte can be used to represent the state or driving command of a certain relay, 0 represents that the state of the relay is falling or the relay has no driving command, and 1 represents that the relay is in a sucking state or has a driving command. The data area and relay correspondence in the data acquisition table is shown in fig. 4(a) and 4 (b): fig. 4(a) shows a correspondence relationship between the drive data area and the drive relay, and fig. 4(b) shows a correspondence relationship between the acquisition data area and the acquisition relay.
In one embodiment of the invention, the bit3 of the byte 1 of the driving data area can be used to represent the driving command of the turnout positioning control relay (DCJ), and when the value of the bit is 1, the turnout positioning driving command is represented; when the value of the bit is 0, indicating a turnout-free positioning driving command; similarly, bit5 of byte 2 in the collected data area can be used to indicate the state of the switch location indicating relay (DBJ), when the value of bit is 1, the collected DBJ is in the suck-up state, otherwise, when it is 0, the relay is in the drop-down state.
When the relay circuit of the outdoor turnout changes, if the turnout equipment adopts three-way turnout, five-way turnout or multiple turnouts, the corresponding position is not only in two states of positioning and reverse, and the binary logic corresponding to the 0 and the 1 lacks the corresponding relationship.
Aiming at the problem, the invention provides a method, an STC system carries out logic operation according to the requirement of route selection and the related interlocking condition and outputs the operation result to a corresponding full-electronic general output module, the full-electronic general output module controls and drives a corresponding relay according to the output result, the output relay transmits the switching information of the turnout to a turnout control system and transmits the control information of related scattered equipment to the scattered equipment control system. The turnout control system completes the conversion of the turnout to a target position required by STC, performs mechanical locking after the conversion is completed, transmits the position indication information of the turnout to the STC system, transmits the indication information of multiple turnouts such as three turnouts through a plurality of indication relays, transmits the state of each position indication relay to the all-electronic general input module, and transmits the state to the STC system after the all-electronic general input module processes the information to perform interlocking logic operation.
When STC system code logic processing is performed, how to process the mapping relation between the relay working area and the full electronic module storage area directly influences whether the full electronic module can correctly control the output of the related relay and correctly acquire the state of the designated relay.
To solve the problem, the invention provides a mapping method between a relay working area and a full electronic module storage area, wherein the relay working area comprises a relay acquisition area and a relay driving area, and the full electronic module storage area comprises an equipment command sending area and an equipment state receiving area.
Firstly, configuring a mapping relation between a full electronic module and a relay
The STC application software writes the drive command into the command transmission area, and designs the command of each device to be 4 bytes, and at most supports the transmission of commands of 800 devices, and all the commands are sequentially arranged according to the configuration information, and the configuration information is shown in control command arrangement table 1:
TABLE 1 control Command arrangement Table
The STC application software stores the received device status in a device status receiving area, can receive the status of at most 800 devices, each device status has 4 bytes, and supports receiving the status of at most 800 devices, and all the device statuses are arranged in sequence, and the device status arrangement table is shown in table 2:
TABLE 2 Equipment status arrangement Table
And a remark column can be arranged in the control command arrangement table and the equipment state arrangement table to remark special conditions.
Secondly, acquiring and converting the equipment state according to the mapping relation
The following modes are mainly adopted for the state acquisition and conversion of each device:
acquiring a device state receiving area of each device;
calculating the offset corresponding to the equipment state receiving area according to the mapping relation between the equipment state receiving area and the relay acquisition area;
acquiring a numerical value corresponding to a state receiving area according to the offset;
and analyzing the relay acquisition area according to the numerical value and converting the relay acquisition area into an equipment state.
The above process is described by taking, as an example, a switch relay and a scattered equipment relay.
The collection and the conversion of the state of switch relay and scattered equipment relay:
acquiring state receiving areas of each turnout and scattered equipment from an STC system, storing the state receiving areas in a buffer1[ ], as described above, the state of each relay corresponds to a bit of a byte in an acquisition area, and if the equipment number corresponding to the relay is usDevID and the channel number of the byte in which the relay is located in the equipment is nChID (the channel number is as shown in FIG. 5 or FIG. 6, and the channel number of each byte is shown in FIG. 6), calculating to obtain the position offset usPosinEEUSta stored in the state information of the equipment, as follows:
usPosinEEUSta = (usDevID-1)*4+nChID-1;
the state value of the device is buffer1[ usPosinEEUSta ].
It should be noted that, like the collection and the conversion of the state of the device that need not pass through relay control, like the semaphore, only need to obtain the state receiving area of each electronic device from the STC system, and deposit in buffer1[ ], during the design, the device number signalNo of a certain semaphore is configured, a certain input unit is set as a device, and the serial number is inputNo, then if the state value of the semaphore needs to be obtained, only need to calculate the offset position that its device state corresponds according to the device number signalNo of the semaphore, then can obtain the numerical value of the corresponding position of the receiving area, according to the signal state that the corresponding numerical value corresponds, map the light color of the semaphore, the state offset usposinseuta that the semaphore corresponds is:
usPosinEEUSta = (signalNo-1)×4
the mapping relationship between the state receiving area of the all-electronic universal input module state device and the relay acquisition area is shown in fig. 5. Each device is designed according to 3 bytes which can be mapped, the state of the corresponding relay can be obtained on the basis of the configured relay position according to the mapping relation, and then the corresponding turnout state and scattered device state are formed in a combined mode according to different relay acquisition values of 0 or 1.
Fig. 6 is a schematic diagram illustrating mapping between a command sending area and a relay driving area of the all-electronic universal output module, where the following driving conversion is mainly adopted for each device:
driving a corresponding driving relay to act according to the formed driving command and setting a corresponding relay driving area;
determining the offset of the equipment in the equipment command sending area according to the mapping relation between the equipment state sending area and the relay driving area;
setting corresponding equipment command sending area data according to the offset;
and driving the corresponding turnout or scattered equipment to rotate to a corresponding state according to the equipment command sending area data.
Illustratively, the conversion of the driving commands of the switches and the scattered devices is taken as an example,
(1) the STC system forms a turnout driving command and a scattered equipment driving command according to the routing intention or the operation intention of a controller, drives a corresponding driving relay to suck up according to the formed equipment command and the logic of a turnout control circuit, namely, a bit of a corresponding byte of the relay in a relay driving area is set to be 1, and if no driving command exists, a bit of the corresponding byte of the relay is set to be 0;
(2) and the STC system application software sets a corresponding relay driving area according to the equipment command, then finds the offset corresponding to the equipment in the equipment command transmitting area according to the mapping relation between the configured equipment command transmitting area of the all-electronic general output module and the relay driving area, and further sets corresponding equipment command output data. And the STC system outputs the device command data to drive the corresponding full-electronic general output module, and then the corresponding turnout or scattered devices are controlled to rotate to the corresponding state by connecting the relay control circuit of the corresponding external device.
