The irrelevant state is determined by matching the state values in a certain order according to the relays whose states are sucking up "↓" or dropping down "↓" in table 3, and if the state values of the relays are consistent with those in table 3, the check is passed and the traffic signal is correctly opened. The other relays are not matched any more, and the state of the relay which is not matched any more is an irrelevant state, and the corresponding state value is '00'.

Taking the lamp color U in table 3 as an example, the corresponding state parameter is "0 x 0008046A", and if the states of the relays DJ, LXJ, ZXJ, TXJ, LUXJ, and DDJ can satisfy the requirements, the state values of the other relays are not considered any more, the states of the relays are irrelevant, and the corresponding state value is "00".

Table 4 semaphore state table example 2

The interlocking system can realize the self-adaptive light color control of the annunciator according to the annunciator command table and the annunciator state table.

Taking the UU lamp lighting as an example, the main program module 11 of the interlock system sends an interlock control command "0 x 0101" according to table 1, and the lighting logic module 12 of the interlock system receives the interlock control command, and then analyzes the command according to table 1, and drives the relays DDJ and LXJ to suck up, and drives other relays to fall down. The acquisition processing module 14 of the interlocking system forms a starting signal state parameter according to the state values of all relay states of the signal, the check module 15 of the interlocking system searches for the signal state parameter corresponding to the signal command parameter "0 x 0101" to be "0 x 0008001A" according to the table 3 to check and match, if the signal state parameter formed by the acquisition processing module 14 is not consistent with the value, the signal is considered to be not correctly opened, and if the signal state parameter is consistent with the value, the signal is correctly opened.

Further, the verification module 15 of the interlock system performs state value matching according to the relays in the table 3 except for irrelevant states, that is, the relays in the states of sucking up "↓" or dropping down "↓" perform state value matching in a certain sequence, and if the relays can be consistent with the table 3, the verification is passed, and the signaler is correctly opened.

And the signal machine command state mapping table is generated by the signal machine command parameters of the signal machine command table and the signal machine state parameters of the signal machine state table according to the one-to-one correspondence of different lamp colors.

Signal machine command state mapping: a mapping table is formed according to different lamp colors, namely a signal command table and a signal state table, the mapping table maintains the corresponding relation between the relay state of signal lighting and the control command, and the mapping relation is synchronous and dynamically variable because the command table and the state table are dynamically variable.

The interlocking system can realize the self-adaptive light color control of the annunciator according to the annunciator command state mapping table.

Table 5 is a traffic signal command status mapping table according to an embodiment of the present invention, which is a mapping table formed according to tables 1 and 3 of different lamp colors, and is not listed in table 5 according to the actions and statuses of the corresponding relays, which is limited by space, and can refer to tables 1 and 3.

Taking the UU lamp lighting as an example, the main program module 11 of the interlock system sends an interlock control command "0 x 0101" according to table 5, and the lighting logic module 12 of the interlock system receives the interlock control command, and then analyzes the command, and drives the relays DDJ and LXJ to suck up and drive other relays to fall down. The acquisition processing module 14 of the interlocking system forms a signal machine state parameter according to the state value combination of all relay states of the signal machine, the check module 15 searches for the signal machine state parameter corresponding to the signal machine command parameter "0 x 0101" to be "0 x 0008001A" according to the table 5 to perform check matching, if the signal machine state parameter formed by the acquisition processing module 14 is inconsistent with the value, the signal machine is not correctly opened, and if the signal machine state parameter is consistent with the value, the signal machine is correctly opened.

Further, the verification module 15 of the interlock system performs state value matching according to the relays in the table 5 except for irrelevant states, that is, the relays in the states of sucking up "↓" or dropping down "↓" perform state value matching in a certain sequence, and if the relays can be consistent with the table 5, the verification is passed, and the signaler is correctly opened.

Table 5 semaphore command status mapping table embodiment 1

Color of light	State parameter of signal machine	Signaler command parameters
			H	0x00080106	0x0100
UU	0x0008001A	0x0101
			USU	0x00A8001A	0x0301
U	0x0008046A	0x0103
			LU	0x0008086A	0x0113
L	0x000800AA	0x0143

In some embodiments, the semaphore state parameter, the semaphore command parameter, and the light color are in one-to-one correspondence, and at this time, the interlock system implements adaptive light color control of the semaphore according to the semaphore command table and the semaphore state table, respectively, and is not much different from implementing adaptive light color control of the semaphore through the semaphore command state mapping table. If the interlocking system realizes the adaptive light color control of the signal machine according to the tables 1 and 3, the difference from the interlocking system realizing the adaptive light color control of the signal machine according to the table 5 is not large.

In other embodiments, the plurality of traffic signal state parameters and the plurality of traffic signal command parameters correspond to one light color, and at this time, the interlocking system can quickly realize the correspondence between the traffic signal command parameters, the traffic signal state parameters, and the light color through the traffic signal command state mapping table.

Table 6 is a traffic signal command status mapping table embodiment 2, and as shown in table 6, for the same light color LU, two sets of traffic signal status parameters and traffic signal command parameters correspond, that is, the traffic signal status parameter "0 x 0008086A" corresponds to the traffic signal command parameter "0 x 0113", and the traffic signal status parameter "0 x000a 400A" corresponds to the traffic signal command parameter "0 x 0183". The annunciator state parameter corresponding to the annunciator command parameter of one light color can be quickly searched according to the table 6.

Table 6 semaphore command state mapping table embodiment 2

Color of light	State parameter of signal machine	Signaler command parameters
			LU	0x0008086A	0x0113
LU	0x000A400A	0x0183
			L	0x000800AA	0x0143
L	0x0008800A	0x0107

If the interlocking system searches for the annunciator state parameter corresponding to the annunciator command parameter of one light color according to the annunciator command table and the annunciator state table, two or more annunciator state parameters may exist, so that the workload is increased when matching verification is performed. If the interlock system searches for the corresponding semaphore state parameter according to the semaphore command parameter "0 x 0113" corresponding to the light color LU of table 2, and the light color LU of table 4 corresponds to two semaphore state parameters "0 x 0008086A" and "0 x000a 400A", both of the two semaphore state parameters need to be subjected to matching verification when performing matching verification, which obviously increases workload and complexity compared with directly passing through the semaphore command state mapping table.

And the interlocking system analyzes the command parameters of the annunciator according to the received interlocking control command and the annunciator command table, and drives the corresponding relay to suck or fall.

Fig. 4 discloses a signaling command parameter parsing flow chart according to an embodiment of the invention. In the embodiment shown in fig. 4, the format of the semaphore command parameter corresponds to the 16-bit parameter value in tables 1 and 2. The signal command analysis process is as follows:

the interlocking system receives a signal machine command parameter cmd;

initializing a cycle variable i, and setting i to be 0;

when i < 16;

sequentially detecting an ith data bit of a semaphore command parameter cmd;

if the data bit of the current position of the signal machine command parameter cmd is 1, driving the ith relay to suck according to a signal machine command table;

if the ith data bit of the current position of the command parameter cmd is 0, no action is taken;

adding 1 to the loop variable i, and continuously detecting the next data bit;

and the above steps are circulated until i is 16, each bit of data of the command parameter cmd of the signal machine is completely analyzed, and the process is ended.

The interlocking system collects state values fed back after all relays perform corresponding actions, and arranges and combines the state values according to a certain sequence to form signal machine state parameters, so that the state parameters are matched and verified with the signal machine state parameters in the signal machine state table.

Fig. 5 discloses a signaling machine state parameter generation flow chart according to an embodiment of the invention. In the embodiment shown in fig. 5, the format of the semaphore state parameter corresponds to the 32-bit parameter value in tables 3 and 4. The generation flow of the signal state parameters is as follows:

initializing a state parameter sta of a signal machine, initially setting two-bit data bits corresponding to each relay to be 01, initializing a cycle variable i, and setting i to be 0;

when i is less than 12;

sequentially detecting the ith relay of the signal machine according to the state table of the signal machine;

if the ith relay state of the annunciator is detected to be suction, setting the corresponding two-bit data bit as 10;

if the ith relay of the annunciator is detected to fall, the corresponding two-bit data is unchanged;

adding 1 to the cyclic variable i, and continuously detecting the state of the next relay;

and (5) the circulation is carried out until the states of 12 relays are all detected, the signal state parameter sta of the signal is output, and the process is ended.

The semaphore state parameter generated in the embodiment shown in fig. 5 does not include a relay whose state is irrelevant, and corresponds to a state value of "00". Therefore, when the interlocking system uses the semaphore state parameter generated in fig. 5 to perform state value matching verification, only the suck-up or drop state of the relevant relay that is in effect needs to be determined, and if the state values of the relevant relays can be matched with the semaphore state parameters in the semaphore state table in a certain order, the semaphore is correctly opened. The related relay is a relay which is sucked or dropped in a state table of the annunciator and influences the lighting of the lamp with the corresponding lamp color. The related relays are relays except for unrelated states.

In the embodiment shown in table 3, taking the lamp color U in table 3 as an example, the corresponding state parameter is "0 x 0008046A", and if the state values of the relays DJ, LXJ, ZXJ, TXJ, LUXJ, and DDJ are related relays and can be matched with the states of the relays in table 3, it is determined that the annunciator is correctly opened, and no further matching is required for other relays.

The method for controlling the annunciator by the interlocking system can be written by using C language or other computer languages and is realized in the interlocking system.

The interlocking system in the invention can be a computer interlocking based on a TECIS (time electric computer interlocking system) platform, and can also be a computer interlocking system of other platforms.

The interlocking System in the invention can be a computer interlocking System Based on a Communication Based Train Automatic Control System (CBTC), a point type interlocking System, an interlocking System Based on a Full Automatic Operation (FAO), a high-speed railway interlocking System or a high-speed railway interlocking System
