[0077] In one embodiment, the present invention provides a method for detecting the operating status of tunnel firefighting equipment. The tunnel firefighting equipment includes a tunnel firefighting pipe and a firefighting water pool of a target tunnel.

[0078] The target tunnel is the tunnel for which the running status is to be checked.

[0079] In this embodiment, several detection points are provided on the tunnel fire protection pipe, and each detection point is provided with a detection device. The detection device has a first positioning module for collecting the position information of the detection point and a detection device for detecting the operating status of the fire protection pipe. The detection device is installed at its corresponding detection point.

[0080] In this embodiment, a liquid level transmitter and a controller with a second positioning module are installed on the fire water tank. The controller is connected to the liquid level transmitter to collect liquid level information of the fire water tank.

[0081] Specifically, if Figure 1 As shown, method 100 includes step 110 and step 120 performed in parallel.

[0082] In step 110, the detection device at the detection point collects the position information of the detection point in real time through the first positioning module and collects the relevant detection information of the detection point through the detection equipment, and analyzes the operating status of the tunnel fire protection pipeline at the current detection point based on the collected detection information. When the analyzed operating status is abnormal, the position information of the detection point and the corresponding detection information are sent to the remote monitoring center.

[0083] In step 120, the controller provided with the fire water tank collects the liquid level information of the fire water tank through the liquid level transmitter and the position information of the fire water tank through the second positioning module in real time, and analyzes whether the liquid level status of the fire water tank is normal based on the collected liquid level information. If not, the position information of the fire water tank and the current liquid level information of the fire water tank are sent to the remote monitoring center.

[0084] The present invention installs detection equipment on the detection points of the tunnel fire protection pipeline and installs a liquid level transmitter on the tunnel fire protection water pool, which helps to monitor the operating status of the tunnel fire protection water system in multiple dimensions.

[0085] Optionally, the detection equipment includes an intelligent pressure gauge, a temperature transmitter and a pipeline flow meter.

[0086] The intelligent pressure gauge is used to collect the water pressure in the tunnel fire protection pipe at the detection point.

[0090] That is, the detection equipment installed at the detection point collects relevant detection information such as the water pressure in the tunnel fire protection pipe at the detection point, the water temperature in the tunnel fire protection pipe at the detection point, and the water flow in the tunnel fire protection pipe at the detection point.

[0091] In specific implementation, the liquid level transmitter can be replaced by a liquid level sensor in the prior art, and the temperature transmitter can be replaced by a temperature sensor in the prior art.

[0092] Optionally, the detection device includes a first controller and the above-mentioned detection equipment, the first controller includes a first communication module, a first control module and the first positioning module; the first control module is connected to the first positioning module and the first communication module, and the first communication module is used to realize communication and data transmission between the first control module and the outside world.

[0093] When in use, the first control module is used to control the detection device. Specifically, the first control module collects the position information of the detection point through the first positioning module, collects the relevant detection information of the detection point through the detection equipment, and analyzes the operating status of the tunnel fire protection pipeline at the current detection point based on the collected detection information. If the analyzed operating status is abnormal operation, the position information of the corresponding detection point and the detection information corresponding to the corresponding detection point are sent to the remote monitoring center through the first communication module to facilitate the monitoring personnel to understand the operating status of the tunnel fire protection pipeline in a timely manner.

[0094] In this embodiment, if any one of the following conditions is met: the water pressure in the tunnel fire-fighting pipe at the detection point is higher than the preset water pressure threshold of the corresponding detection point; the temperature of the water in the tunnel fire-fighting pipe at the detection point is higher than the preset temperature threshold of the water in the tunnel fire-fighting pipe at the detection point; and the water flow rate in the tunnel fire-fighting pipe at the detection point is higher than the preset water flow rate threshold of the corresponding detection point, the corresponding analyzed operating status is abnormal operation.

[0096] The first control module is the control of the first controller and also the control of the detection device.

[0097] The second control module is the control of the second controller.

[0098] Optionally, the detection device on the detection point and the remote monitoring center are both provided with an identification code for uniquely identifying the detection device on the detection point and the remote monitoring center.

[0099] The position information of the detection point and the corresponding detection information are sent to the remote monitoring center, comprising:

[0100] The identification code of the remote monitoring center and the identification code of the detection device on the detection point are obtained, and a random number is randomly generated, the obtained identification code of the remote monitoring center and the detection device on the detection point and the random number are spliced according to a pre-set first splicing rule to obtain a first splicing code;

[0101] The first information and the second information are spliced according to a pre-set second splicing rule to obtain first splicing information; the first information is the position information of the detection point, and the second information is the corresponding detection information;

[0102] The first splicing code is used as a first AES key to encrypt the first splicing information to obtain first ciphertext;

[0103] A first RSA public key is used to encrypt the first AES key to obtain second ciphertext;

[0104] The second ciphertext and the first ciphertext are spliced according to a pre-set third splicing rule to obtain first splicing ciphertext;

[0105] An MD5 algorithm is used to calculate a digital digest of the first splicing ciphertext;

[0106] The first splicing ciphertext and the digital digest are spliced according to a pre-set fourth splicing rule to obtain second splicing information;

[0107] The second splicing information is encrypted by using a pre-set second RSA public key to obtain third ciphertext;

[0108] The third ciphertext is sent to the remote monitoring center.

[0109] Correspondingly, the remote monitoring center receives the third ciphertext sent by the detection device on the detection point, and then:

[0110] The third ciphertext received is decrypted by using the RSA private key corresponding to the second RSA public key to obtain the decrypted second spliced information;

[0111] The decrypted second spliced information is split based on the fourth splicing rule to obtain the split first spliced ciphertext and the digital digest M;

[0112] The digital digest of the split first spliced ciphertext is calculated by using the pre-set MD5 algorithm to obtain the digital digest M' of the split first spliced ciphertext;

[0113] The calculated digital digest M' of the split first spliced ciphertext is compared with the split digital digest M for consistency. If they are consistent (if they are not consistent, a data retransmission instruction is fed back to the detection device on the detection point (i.e., a data retransmission instruction is fed back to the first control module) for the corresponding third ciphertext to be re-uploaded by the detection device on the detection point), the split first spliced ciphertext is split based on the third splicing rule to obtain the split second ciphertext and the first ciphertext;

[0114] The split second ciphertext is decrypted by using the RSA private key corresponding to the first RSA public key to obtain the first AES key;

[0115] The first ciphertext is decrypted by using the decrypted first AES key to obtain the decrypted first spliced information;

[0116] The decrypted first spliced information is split based on the second splicing rule to obtain the split first information and the second information, i.e., the position information of the detection point and the corresponding detection information sent by the detection device on the detection point.

[0117] The first control module can receive the data retransmission instruction fed back by the remote monitoring center through the first communication module, and can perform re-uploading of the corresponding third ciphertext after receiving the data retransmission instruction fed back by the remote monitoring center.

[0118] Optionally, the controller arranged for the fire pool is also provided with an identification code for uniquely identifying the controller arranged for the fire pool.

[0119] The position information of the fire pool and the current liquid level information of the fire pool are sent to the remote monitoring center, including:

[0120] The identification code of the remote monitoring center and the identification code of the controller arranged for the fire pool are obtained, and a random number is randomly generated. The obtained identification codes of the remote monitoring center and the detection device on the detection point and the randomly generated random number are spliced according to the first splicing rule to obtain a second splicing code.

[0121] splicing the third information and the fourth information according to the second splicing rule to obtain third spliced ​​information; the third information is the location information of the fire water tank, and the fourth information is the current liquid level information of the fire water tank;

[0122] Using the second concatenated code as a second AES key, encrypting the third concatenated information to obtain a fourth ciphertext;

[0123] Using the first RSA public key, encrypt the second AES key to obtain a fifth ciphertext;

[0124] splicing the fifth ciphertext and the fourth ciphertext according to the third splicing rule to obtain a second spliced ​​ciphertext;

[0125] Calculate the digital summary of the second concatenated ciphertext using the MD5 algorithm;

[0126] splicing the second spliced ​​ciphertext and the digital summary of the second spliced ​​ciphertext according to the fourth splicing rule to obtain fourth splicing information;

[0127] Encrypting the fourth concatenated information using the second RSA public key to obtain a sixth ciphertext;

[0128] The sixth ciphertext is sent to the remote monitoring center.

[0129] Correspondingly, after receiving the sixth ciphertext sent by the controller equipped with the fire water tank, the remote monitoring center performs the following steps:

[0130] Decrypting the received sixth ciphertext using the RSA private key corresponding to the second RSA public key to obtain decrypted fourth concatenated information;

[0131] Split the decrypted fourth splicing information based on the fourth splicing rule to obtain the split second splicing ciphertext and digital summary M".

[0132] Calculate the digital summary of the split second concatenated ciphertext using the MD5 algorithm to obtain the digital summary of the split second concatenated ciphertext;

[0133] The calculated digital summary of the split second concatenated ciphertext is compared with the split digital summary M″. If they are consistent (if not, a data retransmission instruction is fed back to the controller equipped with the fire water tank so that the controller equipped with the fire water tank can re-upload the sixth ciphertext), the split second concatenated ciphertext is split based on the third concatenation rule to obtain the split fifth ciphertext and the fourth ciphertext;

[0134] Use the RSA private key corresponding to the first RSA public key to decrypt the split fifth ciphertext to obtain the second AES key;

[0135] Decrypt the fourth ciphertext using the decrypted second AES key to obtain decrypted third concatenated information;

[0136] Based on the second splicing rule, the decrypted third splicing information is split to obtain the split third information and fourth information, that is, the location information of the fire water pool sent by the controller equipped with the fire water pool and the current liquid level information of the fire water pool are obtained.

[0137] The second control module may receive a data retransmission instruction fed back by the remote monitoring center through the second communication module, and may re-upload the corresponding sixth ciphertext after receiving the data retransmission instruction fed back by the remote monitoring center.

[0138] When in use, the second control module is used to control the second controller. Specifically, the second control module collects the liquid level information of the fire water tank through the liquid level transmitter in real time, collects the position information of the fire water tank through the second positioning module, and analyzes whether the liquid level status of the fire water tank is normal based on the collected liquid level information (in this embodiment, if the collected liquid level is lower than the preset liquid level threshold corresponding to the corresponding fire water tank, it is determined that the liquid level status of the corresponding fire water tank is abnormal, otherwise it is normal). If not, the position information of the fire water tank and the current liquid level information of the fire water tank are sent to the remote monitoring center through the second communication module.

[0139] It can be understood that the detection devices at the detection points, the remote monitoring center and the controllers installed in the fire water tank in this specification are respectively equipped with different identification codes.

[0140] It should be noted that the identification code involved in this specification can be a digital identification code, an alphabetic identification code, or an identification code composed of numbers and letters. In this embodiment, the identification code is a digital identification code.

[0141] Exemplarily, the method further includes:

[0142] The detection devices at the detection points regularly collect the detection information collected by the detection equipment installed at their respective detection points and upload it together with the location information of their respective detection points to a pre-set data concentrator;

[0143] The controller provided with the fire water tank regularly collects the liquid level information of the fire water tank collected by the liquid level transmitter provided with the fire water tank where it is located, and uploads the collected liquid level information together with the location information of the fire water tank where it is located to the data concentrator;

[0144] The data concentrator regularly uploads data from the detection devices at the detection points and the controllers installed in the fire water tanks to the remote monitoring center.

[0145] It can be understood that the information collection period of the detection device at the detection point and the information collection period of the controller of the fire water pool are both less than the period of uploading data to the remote monitoring center by the data concentrator.

[0146] In this embodiment, the information collection period of the detection device at the detection point is the same as the information collection period of the controller of the fire water pool.

[0147] In specific implementation, the information collection period of the detection device at the detection point, the information collection period of the controller of the fire water pool and the period of uploading data to the remote monitoring center by the data concentrator can be set by the person skilled in the art according to the actual situation.

[0148] Optionally, the data uploaded by the detection device at the detection point to the data concentrator is all encrypted data, and the data uploaded by the controller of the fire water pool to the data concentrator is all encrypted data.
